SUGGESTIONS FOR MITIGATION IN POSTDISASTER HOUSING
USING RECONSTRUCTION AS A TOOL FOR SUSTAINABLE DEVELOPMENT
BIBLIOGRAPHY AND LIST OF USEFUL CONTACTS
A major part of this research was based on the information and guidance provided by CECI's Housing and Social Project coordinators in Honduras, Mr. Francois Audet and Mr. Jorge Guerra, who took valuable time to inform and orient me, and to translate and clarify the information that I needed. Thanks also to Ans De Jayer, the United Nations Development Program (UNDP) coordinator in Tegucigalpa, for her information and help.
I also would like to extend my gratitude to the staff at McGill University's School of Architecture, and particularly to thank Professor Vikram Bhatt, my research project supervisor (director of the Minimum Cost Housing Program), for his continuous feedback, careful observations, and support in providing me with a much needed laptop to take on my research trip. Many thanks to Professor Avi Friedman (director, Affordable Homes Program) for putting up with my frequent consultations and for the valuable information imparted on technical writing through his class "Research Methods."
Many thanks to Mr. David Krawitz as well, for going through my work and offering constructive criticism.
I wish to thank Ms. Marcia King, graduate secretary for the School of Architecture, for performing the thousand and one duties beyond the line of duty that truly contributed to making my experience at McGill a memorable one. I wish also to thank Oxfam Quebec, particularly for the help extended by Mr. Arancibia Carlos for providing me with Oxfam's latest post-Mitch publication (May 1999), which has proved to be both a model and an inspiration to me in the writing of this report.
I owe much also to the Natural Hazards Center at the University of Colorado at Boulder, whose Web site and periodical Disaster Research I have researched and used extensively. Likewise I have also extensively used CINDI, the U.S. government's Geological Survey Center Web page for their images and maps of Hurricane Mitch. Thanks also to the Agency Espanola De Co-operation Internacional, the Spanish Consulate in Choluteca, and Atlas Logistics, a French nongovernmental organization (NGO), for providing me with details of their work in Nueva Choluteca. Lastly I wish to thank a dear friend, Amy Reiswig, whose editorial skills have greatly sharpened this piece of writing.
I hope that my observations on disaster reconstruction, in the context
of post-Mitch Honduras, can serve the greater purpose of allowing us
to question the consequences of international aid on a developing
country, particularly regarding the development of sustainable
solutions in the field of housing.
Previous researchers (Barraclough, 1999; Burby, 1998; Davis, 1978) have correctly pointed out that it is the poor who primarily bear postdisaster losses, tending as they do to live in areas most exposed to hazards and in fragile structures offering little protection.
Given this context, one can begin to understand the effect of natural disasters such as hurricanes, tornados, and earthquakes on vulnerable developing countries, the examples for the present study being the hurricane-prone Central American countries of Guatemala, Honduras, and Nicaragua.
The Honduran government in its National Plan for National Reconstruction following Hurricane Mitch's massive destruction emphasized that "the relation between global climatic changes and phenomena like hurricanes be recognized," and concluded by drawing attention to the importance of hurricane warning systems and other precautionary measures that will need to be taken if massive loss to life and property is to be avoided in the future.
Honduras, a nation of 6.3 million people in an area of roughly 112,087 square kilometers (Roy, 1999, pp. 1-3), is a country which, amidst its neighbours of Guatemala, El Salvador, Nicaragua, and Panama, faces extreme challenges in its efforts toward economic development. In 1995, Honduras' external debt surpassed US$4.1 billion (CNN Online, 1999). When coupled with a 20% rate of inflation, this debt poses an extremely challenging situation to a country already bogged down with economic problems such as poverty, low per-capita income, and unemployment.
The Honduran economy rests largely on banana and coffee production, as well as the harvesting of sugarcane, african palm, shrimp, and other seafood. For an economy that is so highly agricultural, its geographical location between the Atlantic and the Pacific oceans in the Central American isthmus makes it extremely vulnerable, particularly with respect to torandoes, tropical storms, and hurricanes, which have consistently and mercilessly battered its coastlines over the past few decades, destroying much agricultural production. These storms have caused widespread damage to agricultural land, infrastructure, and property, while rendering thousands homeless and setting the economic development of this country back several years.

A closer look at the above chart also shows the specific vulnerability of the northern Atlantic region - the Atlantic ocean being the point of origin for many of these hurricanes.
Because of its geology, much of Latin America is also prone to high volcanic risk. The steady subduction of the Pacific Ocean floor under the western margin of Central and South America has given rise to a chain of volcanoes on the overriding continental plate. The intense interaction of these lithospheric plates in Latin America is responsible for the generation of the almost 270 currently active volcanos (Sigurdsson, 1986, pp. 205) in this region as well as posing a signficant seismic hazard. These factors, when combined with Latin America's vulnerability to seasonal hurricanes, makes Honduras extremely vulnerable to natural disasters.
To obtain a clear understanding of the magnitude of the Mitch disaster when compared with previous hurricanes in the past, the chart below illustrates the wind speeds and destruction levels of different Central American hurricanes in the past ten years.

After an extensive nationwide survey, the Honduran Finance Ministry identified and declared that 73% of Honduran households could be classified as poor (using per capita income comparison) and 30% of these homes as extremely poor. It is this 30%, with their poor quality adobe and mud structures often located near riverbanks and other high-risk areas, that have borne the brunt of Mitch's damage. The United Nations Economic Commission of Latin American Countries (ECLAC) calculated Mitch's damage in Honduras as 80% of the gross domestic product (GDP), and it was the extremely poor 30% of the population that was least able to absorb this huge economic downturn.
Choluteca is characterized by a large number of rivers flowing through it: Rio Choluteca, Rio Texiguat, Rio Grande, Rio Negro, Rio Gaseously, Rio Nacaome, and Rio Vertigo, to name a few. Mitch passed through the state of Choluteca, rapidly creating, with its torrential rain, extreme water levels that found their outlets through the rivers, causing intense flash floods.
Importance of Choluteca's Urban Regional System: Since colonial times, Choluteca, home to almost 200,000 inhabitants, has been an active urban link of relative importance in the commercial and administrative circuit in the Republic of Guatemala. In the past few years it has undergone active developmental efforts that have resulted in the inward migration of people to this province. Yet Choluteca is limited by its poverty when compared to Tegucigalpa or the northern regions, and its rural areas, dispersed along riverbanks or on mountain terrain, are often the first to be hit during the onslaught of hurricanes in the monsoon period.
Again, in Honduras, a country of 6.3 million people, 73% of the population live in poverty and 30% in extreme poverty. Almost 60% of that 30% live in the state of Choluteca (CEPAL, 1999, pp. 178).
Social and Infrastructural Damage Associated with Mitch: Between October 25 and November 2, 1998, Choluteca was the victim of the biggest natural catastrophe in its history, suffering almost incalculable damage to its infrastructure and resources. Hurricane Mitch's impact on the various municipalities of Choluteca was an estimated US$800 million in lost agricultural production alone (Universidad Nacional Autonoma de Honduras, 1999, pp. 98); 10,043.852 quintals of basic grains such as maize, beans, and rice; a further 650.000 quintals of exportable items such as coffee; 20,872.407 quintals of bananas; 3600.000 quintals of sugarcane; and 4046.411 quintals of melon were completely destroyed.
In the educational sector, 25% of the educational centers in Choluteca were damaged; the building of the Central Ministry of Education was completely flooded, lost all of its equipment, goods (furniture), and archives. Numerous health centers were also damaged, with the Hospital of San Larynx being completely destroyed.
In infrastructural damage, 94 bridges were completely destroyed and 75 were severely damaged; in addition, 52 highways were completely destroyed, thereby seriously affecting north-south accessibility.
In the service sector, approximately 22 aqueducts between the cities of Tegucigalpa and Choluteca were damaged, affecting 70% of the potable water provided to Choluteca.

Another reason for the increased disaster vulnerability of this state is an ecological imbalance due to deforestation. The absence of root systems to hold soil in place makes it more vulnerable to landslides. It is estimated that 108,000 hectares in Honduras disappear annually due to continuous deforestation.
1) Bajareque or Wood Frame-Mud Plaster Houses: This type of housing is common amongst the poorest section. It consists of a basic frame of unfinished wooden poles or tree branches, finished using mud plaster (or cement, depending on the resources of the family) as an infilling material. Mitch greatly affected this type of construction, which, because of the poor quality of its material, was prone to collapse and disintegration with heavy rain.
2) Adobe and Tile Construction: This second type of rural house construction is found extensively in the eastern parts of the state, particularly along the mountain slopes of El Corpus, and in certain areas of Perspire, San Larynx, Choluteca, and El Triunfo. This type of construction uses adobe blocks, locally made using the area's clayish mud. As the clay content in the mud is high, these blocks are cohesively packed and are durable. Depending on the financial capacity of the family, either cement or a cement-clay mixture is used as mortar filling. These adobe walls are sometimes plastered using mud and a horse/cow dung paste. In certain cases, the exterior is plastered with cement plaster. Most foundations are set on a rubble platform3. The roof is made of timber log frames with smaller log or bamboo rafters that act as supports for clay tiles. Limited use of asbestos or zinc is found in traditional house construction, with most families preferring clay tiles because of topographical, cultural, economic, and accessibility factors.
3) Brick Walls with Tile/Zinc/Asbestos Sheet Roofing: This is the third, more expensive type of construction found in regions of Perspire and central Choluteca. The walls have a framework of concrete4 with brick infilling. Wooden roof frames are embedded into the brickwork, and the joints are set in cement mortar. Terra cotta tiles or sheeting make up the roofing5. For this type of housing, it has been difficult to collect data on the connections between the beam and the brick infill and to know if the use of lateral reinforcement is common.
4) Concrete Block and Tile/Sheet Roofing: This is the fourth type of house construction, with walls being made of 400 x 200 mm concrete blocks set using cement mortar. Vertical/horizontal reinforcements are placed in the hollows of these blocks, which are then filled with cement mortar. The wooden roof, door, and window frames are set into the structure and sealed using cement. This is the strongest type of construction and is found most often in semi-urban or urban areas. This form of house construction was little damaged during hurricane Mitch6.

The above findings show that the majority of dwelling units, that is, two out of every three, are self-owned (property with and property without title), the properties without titles representing the poorer segment's land-encroachment into rural areas and the preference towards self-ownership. The data below shows the type of construction that is popular on this type of land.

It is clear from the above data that the most common type of dwelling unit is the detached, independent, self-owned housing unit. Below are the results from a survey of 824 units within the state of Choluteca, demonstrating the most common types of wall material used and thus indicating local preferences and choices.

For example, the data below demonstrate that high wind resulted in less damage during Mitch compared to avalanches and flooding. Although one must consider seismic, hurricane, volcanic, and other factors before actually designing structures, the chart below can help one learn from the experience with Hurricane Mitch.

The above figures clearly show that most housing damage was due first to flooding and second to landslides.
Likewise, the figures shown below indicate the degree of damage to the dwelling units due to Mitch, also pointing out that a majority of houses were completely destroyed, thereby necessitating reconstruction7.

Finally, the urgent need for reconstruction is further confirmed when one notices that as of February 1999 over 700 families in Choluteca were identified as having completely lost their houses and as requiring urgent replacement housing8.
A survey conducted by students of the Postagrado Latino Americano En Trabajo Social further indentified where these families were staying, thereby confirming that for many, finding alternate accommodation was a impossible and living in shelters with minimal facilities was the only solution.

To take the example of the municipality of Perspire, evidence suggests that the central government there had very little involvement or interest (Audet, 1999) in the reconstruction efforts organized by the various nongovernmental organizations (NGOs) and international agencies during the initial planning stages following the disaster (January-February 1999). However there seemed to be greater involvement on the part of local municipalities, who, apart from playing an important role in the procurement and allotment of the land, also assisted the NGOs in their determination of those families who needed immediate attention. The "laid back" attitude of the government amidst of the flurry of reconstruction efforts by international NGOs in Nueva Choluteca seemed to indicate that corruption was prevalent amongst most political bodies in Honduras (Honduras This Week, 1999), inspite of (or due to) the millions of dollars of international investment9 since October 1998.
Most international reconstruction efforts in Honduras have centered around the following issues; participatory vs imposed solutions, traditional vs imported technology, rural vs urban space creation, and costs of construction vs costs of maintenance (Atlas Logistics, 1999, pp. 4). However, the solutions provided have been extremely diverse. This diversity reflects methods of conception, housing design, technological choices, costs, interior and exterior arrangement, issues of land ownership, and extent of aid offered.
In this context, it is interesting to note the approach to reconstruction of the Canadian NGO Centre d'Etude et de Cooperation Internationale (CECI). While some organizations have preferred to benevolently offer ready-made houses, CECI has focused on people's participation in their reconstruction - on enabling people to initiate their own development, thereby working towards long-term progress. Within this context it is necessary to mention the "Auto-Construction" system followed by CECI, which provided families with building materials, requiring them to become involved in the actual building process. The system is similar to a "sweat equity" program, imparting valuable construction skills to the people10. This method of "Auto-Construction" or "Participatory Development" has proved to be a successful tool in many cases, resulting in greater occupant involvement in reconstruction.
Still, researchers have always pointed out that the most important role external agencies interested in postdisaster reconstruction can play is to help build indigenous institutions, those that will be equipped to meet the communities' needs in the future. Examples of how international aid has totally missed this mark in the past reflect foreign policies and technology that often contrasted sharply with local needs and preferences (Dudley, 1989). However, with the growing number of natural disasters in the past few years and the consequent specialization of disaster- relief, more and more organizations are trying to integrate their reconstruction efforts into grassroot development, making use of local talents, techniques, and construction practices.
An earlier example is CAAP (Centro Andino de Accion Popular) in Equador, a South American volunteer organization, active following the March 1987 earthquake, that integrated into its reconstruction plan (in a country in which it did not have much previous experience) many grassroot development strategies, such as prioritizing building education, providing a construction tool kit for every family so that they could participate in their own reconstruction process, and allocating a salary for a local master builder for a period of six months (in order to increase local capacity for reconstruction work).
As Wijkman and Timberlake have observed, "In order for any reconstruction aid to be useful, it is essential that provision should start within 10-20 days of the disaster so that the support is according to the reconstruction timetable of the survivors, not of outside agencies (Wijkman, 1984)."
The experience in Equador proved that prefabricated, prefixed, imported technology from outside countries did not contribute anything to local building practices and skills, nor did it enhance a communities' long-term sustainable development. On the other hand, self-help solutions, i.e. providing materials and requiring the people themselves to provide the labor, resulted in increased participation and local responsibility.
To summarize, in the context of international aid, true development, following a disaster or not, should and will take place through the strengthening of indigenous skills, infrastructure, and organizations. The best hope for a community's recovery in a disaster situation lies in the availability of such strong organizations.
It is towards this end that local institutions must direct their efforts. Indeed, foreign aid agencies must support these institutions in developing their local understanding and organizational infrastructure before the disaster strikes, if true recovery is to be achieved.
UNICEF: A division of the United Nations officially concerned with the Childrens Education Fund, UNICEF in Nueva Choluteca has been involved in the reconstruction of three school buildings within the Nueva Choluteca premises (negotiations for two of which are underway).
Samaritan's Purse: A charity-based international organization, Bolsa de Samaritana (local translation) has been extensively involved in Nueva Choluteca not only in the provision of permanent housing but also in the provision of water purification filters, which it has widely distributed.
Atlas Logistics: A French NGO specializing in disaster relief, transportation, and logistics, Atlas Logistics has extensively contributed to the construction of over 250 housing units in Nueva Choluteca, apart from drilling borewells and arranging water for construction and community use.
CECI: Centre des Etudes et Cooperation International, a Canadian NGO involved in the provision of housing units, latrines, kitchen stoves, has also been involved in a social organization and orientation project in Nueva Choluteca.
MSF: Medicine Sans Frontiere is a Swiss NGO involved in the provision of immediate medical relief.
Action Contre El Hambre: Action against Hunger is an international NGO that has also contributed to permanent house construction by participating in the food-for-work program.
OIM: Organization de Immigration et Migration, a United Nations division involved with refugees and migrants, has been responsible for the provision of temporary shelters for over 2,000 families in Nueva Choluteca - families who are waiting for the completion of their permanent houses.
Consulidad Espanol: The Spanish Consulate in Honduras, which has not only contributed to house construction in Nueva Choluteca, has also opened a training school "Escuela Taller Especial De Choluteca (Funes, 1999)" through which it has begun training local people in carpentry, welding, and construction. The consulate has initiated many long-term training programs involving local youth.
Save the Children/Honduras: An NGO originally working exclusively with displaced, affected children, Save the Children has diversified in Nueva Choluteca, involving itself in the construction of housing units and many food-for-work programs.
Iglesia de Cristo: A local Catholic charity organization, Iglesia de Cristo has also contributed to the provision of housing units complete with water supply and sewage provision.
Again, while the work of external agencies in the resettlement process is commendable, one cannot overemphasize the real importance of "internal aid" in a country during a disaster. While relief is mostly mobilized from outside the stricken country, "planning" for recovery and mitigation must necessarily be undertaken from within each country, taking into account available indigenous resources.
Although CECI's initial goal was to build 800 homes, as of this writing over 990 houses have been completed in Honduras, together with 250 kitchen stoves and individual latrines in Nueva Choluteca, apart from sewage and potable water projects in Conception de Maria and Perspire. Below is a table listing all of CECI's projects in Choluteca, with the specific number of units built in each area.
In many cases, CECI worked in collaboration with other national and international NGOs. For example in Nueva Choluteca, Atlas Logistics took over the actual construction of the 52 CECI units, although the financial responsibility of these was CECI's.

The following summaries provide some idea of the financial partnerships between CECI and other organizations that made the realization of the 925 housing units in Choluteca possible. They describe the different projects and financial involvement of CECI in the diverse cities and towns of Choluteca, and provide details of collaboration with the other agencies (CECI, 1999).
Perspire (semi-rural): Located in the northern tip of the state of Choluteca and approximately 105 kilometers southwest of Tegucigalpa, the municipality of Perspire included many populations living in close proximity to the rivers of Perspire, St.Juan, and Tapaloca. This vulnerability, combined with the intense poverty in this region (mud and adobe houses are very common), made these communities extremely vulnerable to Mitch's onslaught. Many houses close to the river were completely destroyed by inundation, and entire village settlements were completely flooded. CECI is involved in nine different areas of Perspire, three of which the author had the opportunity to visit personally. These areas consist of many reconstructed houses and some relocated ones. Almost 65% of these reconstructed houses have been built at the same site as the original damaged houses, often on the existing foundation of the old buildings13.
CECI has extensively used concrete frame, brick infill construction, together with wooden frames and tiled roofs. However, as discussed in the next chapter, the primary issue of mitigating the effects of future flooding remains14 - i.e. site location has been under severe constraint in this area - first because of municipal limitations, second, because of the unavailability of purchasable land. Therefore it seems only a matter of time before another hurricane-induced flood will endanger these homes. Still, the new houses are well-constructed; they are concrete beam frame and brick infill structures replacing, in many cases, adobe and poor quality brick structures that easily collapsed during the three days of intense rain and flooding brought on by Mitch in October 1998.
A small percentage of the units here have been built anew, including a group of 15 houses that are the only ones that have been relocated. One can see how the siting of these houses (staggered alternately along the upper slopes of the mountains) has definitely lessened their vulnerability to flooding, should the adjoining river overflow. Given that this community represents the poorer segment of Perspire, with virtually no public facilities to boast of, CECI's project of building a 100-cubic-foot septic tank, using the natural slope of the site to drain recently laid pipes from these newly constructed units, definitely serves an important public need, apart from being an important step in promoting the community's self-sufficiency.
Conception de Maria (rural): The housing units provided by CECI in the El Corpus and Conception de Maria regions are different from those mentioned above and below because they have been built in a unique area with its own set of restraints. Located close to the Nicaraguan border, the El Corpus region is characterized by its high altitude, and it is not uncommon to find most shelters built into the mountain slopes. This region of Choluteca has a high population and is one of the poorer segments of Honduran society, most of the local structures being made of adobe and tiles. During Mitch, part of the loss of housing units in this region was due to landslides and flooding that often brought down entire structures. One of the biggest constraints in this extremely rural, inaccessible part of Choluteca involves the transport of building materials15, and the use of concrete blocks was not justified due to the high cost of transportation. Hence, after much consideration of local preferences, adobe has been extensively used in reconstruction. Almost 50% of the 533 units built here have been reconstructed in the same area as the damaged structures - over the previous building's foundation or close to the original building.
Again, an important issue in this project is mitigating the effects of future disasters through reconstruction. This region, due to its geographical location and the use of adobe construction locally, will continue to be vulnerable to disasters, and it is only a matter of time before history repeats itself. However, since relocation would be a difficult and complex alternative16, this problem remains and will require further careful analysis by professionals and housing specialists in this field.
El Triunfo (rural): Located southwest of the El Corpus region, El Triunfo is geographically similar to El Corpus, and most of the reconstructed houses are characterized by adobe and tile. CECI has undertaken a small project and has constructed twelve units here.
San Lorenzo (urban and semi-rural): In San Lorenzo CECI has been involved in the provision of 188 housing units, with the support of Save the Children/Honduras and the construction involvement of Atlas Logistics. The houses have been built using bricks and tiles, and close to 70% of these reconstructed houses have been relocated to a safer spot, often within a few meters of the original site, away from the path of possible landslides.
Nueva Choluteca (urban): The project in Nueva Choluteca (also called Limon de la Cerca) involves approximately 1,300 units built by various organizations on a site of 117 hectares, 15 kilometers away from the city of Choluteca. The land belonged to a bank, Bank Occidental, that allowed the residents involved in this project to purchase the land on a monthly installment basis. This project is the only one amongst the others previously described in which there is large-scale relocation of the units into new area, with the idea of initiating growth of the city (thus the name Nueva Choluteca). However, CECI has constructed only 52 units on this site, the site having 2,154 lots available with approximately 1,100 units built so far. An important factor in CECI's involvement in providing just 52 houses, but also in its involvement in providing over 250 latrines and kitchen stoves, is the organization's recognition that the most pressing need at this site is facilities that can make this community sustainable in the long run, and not in just the provision of more and more housing units.
For the 1,300 units constructed (and, potentially, for approximately 850 more), the provision of water supply systems, sewage, latrines, electricity, and potable water has not been adequate. CECI's recognition of this fact has resulted in its becoming involved in raising the general standard of life here by constructing latrines and kitchen stoves17, and in also promoting the environmental development of this area by supplying hundreds of tree saplings to be cared for by those occupying these new units.
One of the reasons why the Nueva Choluteca or Limon de La Cerca project
was specifically chosen as a case study is that it is the only
project in Choluteca wherein a postdisaster
community was actually planned in a new area on a large scale and with the ultimate goal of
relocating residents to a safer zone (the project is also the biggest, with
2,154 lots allocated). In order to examine and discuss a
sustainabile reconstruction project, it is important to choose
a community project wherein the reconstruction involved
mitigation and was initiated "from scratch" - particularly if one is keen on studying the sustainability of relocation.
Nueva Choluteca/Limon de la Cerca
Another important consideration was that this site includes approximately 1,300 units built by seven or eight different organizations, resulting in five different housing types within the same site area, all involving interesting variations in designs, materials, costs, and construction.
Lastly this site was chosen because these units represent typical "disaster reconstruction," i.e., houses specifically built for Mitch victims, without the limitation of having to adhere to the previous house profile. Following is a description of the present project in Nueva Choluteca.
The site plan includes two principal streets of 12 meters width, facade to facade, 3 meters on each side, green space inclusive, the houses on either side having to respect this setback. Within this total available area of 6,400 sq.m., eight blocks of 32 strips of 10 x 20 meters became possible. Therefore each nongovernmental organization involved in reconstruction has a 10 x 20 meter lot specification they must adhere to. Honduran code requires that 3 meters of setback from a main road. All the houses constructed respect these criteria and are also located on the right-hand side of the plot, thereby allowing 4 meters of space between each unit. The list of NGOs involved in Nueva Choluteca includes Atlas Logistique, Caritas, CDM, IHNFA, ALCALDIA Municipal, Cooperation Espanola, CECI, United Nations OIM, DGIC(Policia), Policia National, Adras Area Metropolitana de Salud, Iglesia de Cristo, Cuerpo de Bomberos, Cruz de Maltaiglesia Santidad, Bolsa Samaritana, Bebiendo Del Manantial, Escula Ricardo Sorano, Help Honduras, Finca Honduras, Auxilio Mundial, Fondacion Covelo, AID-UG, Medicos Sin Frontera, Gobernacion Politica and Action Contre El Hambre18. (Those in italics are involved in reconstruction.)
1) OIM-built Temporary Shelters: Since January 1999, when this 117 hectares of land in Nueva Choluteca was confirmed as the reconstruction site, OIM (Organization International of Migration, a division of the United Nations dealing with relief supplies to disaster/refugee populations) has built approximately 850 temporary shelters for families waiting for permanent houses. These temporary units consist of a basic wooden frame with plastic sheeting and gypsum panels (all materials being reusable). Zinc sheeting is used as the roofing material, and a meshed opening is provided in place of a window, which is covered with plastic sheeting (provided by the OIM) in case of rain. When a family is relocated into a permanent structure, it is common to see these materials being reused as extensions to the new housing unit, or for a small pulperia, a small common condiment store. Since the beginning of the year, 1,200 such shelters have been constructed and occupied by those awaiting permanent houses.
2) Concrete Block with Zinc Sheet Roofing: This type of house construction was used in a majority of the 1,300 existing units. The plinth is raised by 300 mm, resulting in a concrete floor. Exposed cement blocks with cement mortar joints form the four walls, with wooden window and door frames being embedded into the openings sealed with cement mortar. The roof frame is made of wooden planks, which in turn support the zinc roof. This type of construction was also used extensively for the houses provided by Bolsa Samaritana and Action Contre El Hambre.
The two disadvantages of this type of construction are first, that zinc as the roofing material is poorly suited for the extremely hot climate of Choluteca19, and second, that during the rainy season, zinc sheets produce a deafening noise as the rain lashes down.
3) Plastered Walls with Zinc Roofing: This type of housing unit has been provided by the Catholic Church in Choluteca; it consists of cement block walls, plastered and painted using cement plaster on the outside (left exposed on the inside), with zinc sheeting on a wooden framework. What distinguishes this unit from the others is the allocation of interior space. While most NGOs, after a careful study of local lifestyles and preferences, decided not to build the kitchen unit indoors, preferring instead to provide outdoor stoves, the builders in this case elected to include a kitchen unit as well as a bathroom complete with fixtures (bath space, washbasin, w/c unit) indoors, as well as to provide for water supply (a separate tank with supply pipes has been laid out exclusively for these units). The higher cost per unit involved with this type of construction raises two important questions: first, whether or not it is better to provide more housing units catering to more families, but with (few) basic facilities, or a fewer number of units with more facilities for fewer families; and second, whether or not imposed solutions (as opposed to vernacular solutions) are sustainable on a long-term basis. Indeed, it is interesting to note that even though these indoor facilities have been provided, families still cook and wash outside, using makeshift stoves and benches (see photographs, Annex B).
Another important drawback in the plastered-wall-and-zinc-roof type of construction is the unfinished roof/wall connection, which displays a lack of construction experience on the NGO's part20. Also, most families have added their own grill work in front, thereby demonstrating their own priorities and preferences.
4) Cement Block Units with Tiled Roofs: This fourth type of housing unit has been provided by the CECI and Caritas (accounting for 250 out of the 1100 units built) and constructed by Atlas Logistics21.
This type of construction involves exposed cement blocks and wooden window, door, and roof frames (similar to the elements used in the second category), but it uses terra cotta tiles instead of zinc laid on wooden rafters. The hipped edge of the roof as well as the edge tiles are fixed using cement plaster. The interior layout of these units includes four rooms, the fourth one being smaller in size (easily convertible into a future kitchen/bath area). All internal walls are 9 feet high.
5) Concrete Block, Tiled Units Provided by Consolidad Espaniol: These units, although they make use of materials similar to those just mentioned above, are different because the cost per unit is higher and they include a bathroom and a small kitchen, besides providing for two additional future bedrooms. This type of construction has been listed as a separate category, and it will be discussed comparatively further on in this report22.
Borewells with pumps and tap outlets exist in different locations throughout the site (see photogaphs, Annex B).
To conclude, regarding the provision of water, it can be said that one of the biggest problems is the lack of a centralized, organized solution to water supply23 in this community.
Sewage System: Again, there is no common, centralized sewage connection. The unpopularity of community latrines in the past24 has resulted in the construction of individual pit latrines, randomly located, totalling approximately 250 units, with the construction of another 500 units underway.
Each pit latrine is made using a two-meter-long, one-meter-wide plastic tube, buried into the ground. The bottom portion of this tube is finished with a 150 mm concrete base. Pit latrines are designed with a one year capacity, after which they require manual removal25. However, municipal sewage outlet pipes have been provided to these pits, and they can be easily be connected to the main sewer line. Common septic tanks have been provided by certain NGOs who have built toilets within their units, and all such units have been connected to this common septic tank. CECI has recently begun a 400 latrine project for those units currently lacking a sewage system.
Electricity: Currently none of the units have electricity. Although relief donations have resulted in the municipal government's erecting electric poles, and illegally tapped lines are in current use, legal supply has not yet been sanctioned. Thus electricity is another basic infrastructure element that is lacking but that has been promised in due time.
Social Infrastructure: Due to the combined efforts of Atlas Logistics and L'Order de Malte, it was possible to finance the construction of a health center for the use of the 1300 families in Nueva Choluteca, thereby making it unnecessary for them to travel 15 to 20 kilometers to the main city to find comparable services. The temporary office complex constructed by CECI and Atlas Logistics (see designs, Annex B) within the site complex serves as a common point for community meetings, discussions, and training sessions. Currently one of the CECI-designed houses is being used as a kindergarten, and four temporary cement-panel-zinc-roof units are being used as a primary school.
As this report was being prepared, UNICEF and CECI were negotiating for the construction of four more units to include the kindergarten within the primary school complex, and plans are underway for the construction of a 600-student school within an allotted acreage in Nueva Choluteca26 (see designs, Annex B).
Also at the time of this report, no centralized market existed, although an increasing number of small shops like pulperias had opened, with people still travelling to the main city market for major purchases. Also there was no church on this sites27, nor any other type of integral community infrastructure, the Catholic Church being integral to most Latin American cultures.
Basic Design: Each unit measures approximately 6.15 x 6.15 meters (exterior dimension) (see plans, drawings, photographs, Annex B). Each unit consists of four rooms: two bedrooms, one living room, and a smaller kitchen/store. Every house has two doors, one main door and another back door, keeping with local customs and preferences28. Every unit has a sloped tiled roof, made of terra cotta tiles on a wooden framework, the slope being appropriate for a region having a distinct rainy season (July-November). CECI has also provided a separate outdoor kitchen stove unit as well as an individual pit latrine for most of the 250 families involved.
Foundations: The foundation of these housing units is laid on a rubble and concrete platform, raised 150 mm to prevent seasonal flooding. The edges of this platform have a horizontal reinforced ring beam running alongside, connecting the corners (see photographs, Annex B). As Choluteca is an area prone to seismic activity, these horizontal beams serve to counter the shear stresses produced during earthquakes. Each corner of these houses has larger concrete blocks (20 x 20 xx 40 mm) fitted with three 10 mm diameter steel bars through their hollows, laterally braced every 150 mm c/c and compacted with cement concrete. The foundations go into the ground upto a depth of 1.5 meters.
Superstructure: The four corner reinforced cement block columns support the load of the roof above. Apart from these four columns, the intersection of the interior walls is reinforced, thereby resulting in an integrated and strong superstructure. The walls are built using 10 x 20 x 40 cm blocks, their hollows filled with rocks and cement mortar. These blocks are also laid using cement mortar. At the lintel level, again 20 x 20 x 40 cm blocks with a special provision for lateral reinforcement are used (see photographs, Annex B). This horizontal ring beam helps in distributing the roof load, apart from dispersing the shear stresses caused.
Roofing: The roof of every CECI unit is made up of approximately 1700 terra cotta tiles - an average of 34 tiles per meter square. Fabricated with a locally available clay, this type of roof has the additional advantages of encouraging a number of small-scale, local manufacturers, being relatively inexpensive, and being easily replaceable with unsupervised labor not requiring high-skilled technicians. Due to their increased thermal efficiency in hot climates and their overall adaptability, tiles were found to be a suitable choice for roofing material in this region.
Latrines and Kitchen Stove Units: Individual latrines have been provided outside of the CECI housing units. The latrines use cement panels attached to a wooden framework and have sloped zinc sheet roofing. One meter diameter plastic pipes are embedded into the ground and their bases sealed with 150 mm of cement concrete. A vent pipe is provided from this pit area to the outside for the emission of toxic gases, and a sewage outlet is provided for future connection into a municipal sewer line. The kitchen stoves are located outside of the house, often under an extended roofline. They are built at platform level and consist of a concrete mould with a specific area for burning wood.

What strikes one in Nueva Choluteca is not the different types or quality of housing provided, for indeed there are plenty of varieties and a high quality and standard of living has been attempted (Housing units provided by Espanol Consulidad - see drawings in Annex B). Rather, most noticeable is the visible shortage of adequate infrastructure for the 1300 odd families already occupying the newly built units. Water supply for this large community still relies on borewells, necessitating the use of pumps, which again need electricity that still has not been comprehensively provided. Most of the water supply system is still piecemeal; families need to carry water from wherever the outlet taps are located, and only a small percentage of homes have water pipes connected to an existing borewell and storage tank. Provision for sewage is limited to individualized pit latrines that are randomly located - all designed for a two year period, provided they are not used as a waste water system (i.e. for bathing etc., which they often are). Surprisingly there is no provision for bathing, either because the community previously lived in areas near the river, or simply because there was no easy solution to providing thie amenity.
This brings us to the important question for international aid organizations of where and how international reconstruction and aid should be focused. Is it in providing more housing or in improving infrastructure? Can the high standard of facilities provided within the constructed unit be offset or complemented by allocating resources for community infrastructure such as sewage outlets, stormwater drains, or municipal water supply?
When asked about the problems inhabitants of this new community face29, most families cite water supply and employment opportunities as burning issues, while they almost unanimously agree that the standard and quality of housing provided in this community is far better that what they previously had.
Clearly, in order for this project to result in a truly sustainable community, i.e. a community that will continue to grow and thrive with time, it is essential to focus on the all the needs of the community and to pursue the true objectives of international aid - to empower people locally and go beyond mere restoration of the status quo. International organizations must ask whether their aim is just providing houses as a replacement for those dislocated, or developing communities that are sustainable on a long-term basis - communities aware and equipped to mitigate and deal with future disasters.
Some of the factors that require careful attention include:
Additional examples of flooding in Vietnam, Orissa, Belgium, and France in 1999 all point to a single conclusion: it is those that occupy and live in risky areas - areas prone to floods and landslides when storms strike - that form the most vulnerable group. Waiting for a disaster that kills thousands of people and displaces millions of others to convince us of the importance of the issue of location is absurd. The huge losses in the countries cited and in the Central American countries of Guatemala, Honduras, El Salvador and Nicaragua during Mitch, could have been avoided to a great extent if only there had existed (on the part of the public, government, and local authorities) an increased awareness on the urgency of predisaster measures.
Thus the increased cost of disasters is due not only the fact that disasters are occurring more often in the world, but also that they are affecting increasing populations living in risky areas, in poor quality houses. Specifically, within the context of flood mitigation, it has often been found that often little regard is given to the placement of houses in relation to danger from hurricanes. Good site location or orientation taking into account local terrain and natural cover can be, but usually is not (at least as seen in previous case studies of governmental land allotment for affected people in developing countries such as the Philippines, Bangladesh, Turkey. etc.) determined from historical hurricane data. This data provides the frequency, velocity, and direction of prevailing hurricanes, especially in their extreme form. Most importantly, if this data were taken into account, flooding damage could be averted by siting people away from risky areas such as coastlines and mountain slopes. The importance of siting cannot be overemphasized. The concept of landscape and terrain as a factor in wind-resistant design has long been formally established long since (see Burby and Snarr), although its effective use in actual postdisaster recovery and development still remains grossly inadequate. While other research has previously pointed out the magnitude of this problem, local governments still often turn a blind eye to predisaster measures, waiting until a disaster actually strikes to take action.
The success or failure of postdisaster resettlements has been shown (A.O.Smith, 1992) to depend upon the four factors of siting, layout, construction, and owner participation (Oliver-Smith, 1992) (Nueva Guatemala, or the old city of Antigua, being an example to this effect). Somewhat similarly, Coburn et al., in discussing the successes and failures of resettlement in Bingol province in Turkey have suggested that three factors are crucial in determining the success or failure of a resettlement project; the physical environment of the new settlement, the relationship to the old village, and the capability of the community to develop itself (Coburn, 1992).
Coburn also maintains that viability can be assessed by examining the following factors; the number of houses still occupied, the modification of the form and internal layout of the housing provided, the degree of maintenance required and state of repair, the extent of buildings and the degree of investment, and the construction of private buildings on the reconstruction site.
Other factors highly conducive to the success of the displaced community are the proximity to gainful employment and the provision of basic social services.
Therefore it is imperative that a local government avoid hazardous areas when siting community facilities such as water, sewage, transportation, and other basic infrastructure, and that it establish a policy of issuing building permits only for buildings that are located in nonhazardous areas.
To conclude, appropriate siting can only be achieved when there is a comprehensive land-use planning approach, i.e. mitigation measures must be integrated with other community goals.
Housing design and construction are also often blamed for the rejection or failure of postdisaster resettlement projects. Faulty construction and inferior materials become quickly evident when housing units are occupied; they create difficult living conditions, particularly with respect to thermal protection in different seasons (Oliver-Smith, 1992; Razani, 1984; Coburn et al., 1984; Lamping, 1984). Disaster reconstruction in the same disaster-prone location using the same unsafe building techniques is not uncommon. Even if relocation takes place, the design of resettlement houses is often inappropriate for domestic activities that require different kinds of spaces for different uses according to the seasons. Failures often occur because the people for whom structures are built are not consulted, with the consequent lack of understanding of their socially and culturally derived needs and values, as well as of their intimate knowledge and long experience in the local environment.
Compounding this lack of understanding of local needs and values is the frequent importation of outside labor to construct the settlement itself, which not only robs the people of a sense of participation in their new village but also deprives them of the opportunity to gain new and relevant skills for jobs in a developing economy (Oliver-Smith, 1992).
Ultimately, successful postdisaster resettlement is far more than just the construction of stronger concrete block or cement housing. How reconstruction takes place is perhaps more important than what, or how much, is done. For post-Mitch Honduras it is clear that when reconstruction is seen largely as an economic and technological problem (i.e, when the principal concerns are the efficiency of the building system, either as a mitigation measure or as a construction technique), the chances of success of the project are reduced. On the other hand, when postdisaster reconstruction and resettlement are approached as sociocultural, as well as material, problems, and when the victim population participates in planning and implementation, the chances of success are greatly enhanced. Additionally, if the importance of viable employment for victims is recognized, the chances of successfully moving on to a post-resettlement stage are also improved. A close look at the resettlement community at Nueva Choluteca shows that well-constructed strong housing does not necessarily constitute sustainable architecture. There are at least two other prerequisites for this community to become sustainable. First, the 2,100 lot housing community must have public infrastructure that is designed to meet the needs of the 1,750 families that have already occupied their new houses. Stormwater drainage, an efficient sewage system, provision of electricity, and the supply of municipal water are all important prerequisites that go hand in hand with a growing community. Second, it is imperative that opportunities for gainful employment be created close to the new area as opportunities for those people who lost their previous source of income due to their displacement.
In conclusion, disaster recovery and relocation must embrace a a comprehensive approach if it is to result in a sustainable community; it should include not just house reconstruction but all other elements of individual and community development.
Design: It is possible to make buildings more storm resistant by improving their connection details. By learning more about the effects of wind on buildings and by avoiding certain shapes or groupings of buildings one can also avoid undesirable aerodynamic effects.
Obviously, one must consider possible inundation, particularly in areas that experience an intense rainy season. The nature of flood and landslide destruction can be understood by closely studying partially destroyed buildings immediately following a disaster.
Certain design elements can increase resistance to high wind and rain. Sharp edges, low-pitched roofs, large overhangs, and improper grouping of buildings can cause problems (see figures 1 - 9, Annex B). The aerodynamic behavior of buildings is often improved by providing rough surfaces or ribs on the exterior of the walls. Grass roofs have allegedly served to relieve pressures, as have smooth transitions between building surfaces. Unfortunately, internal pressures in buildings with openings are usually not sufficiently considered in design. Roof failures have been caused by wind that penetrates a structure and presses up on the roof from beneath.
Certain configurations (such as cylinders and igloo-type designs) are far more stable than box-like structures, but in the few places where they have been tried, local cultural attitudes have led to their rejection and abandonment. In most developing countries, it is often hard to separate design and construction, most houses being constructed by local masons and contractors.
Characteristics - Foundations, Walls, and Roofs:
Foundations: In low-rise buildings, load transmission to the soil becomes less critical since dwellings of one or two stories do not generate a high dead load. Where flooding is not common, rectangular footings of plain or reinforced concrete or gravel are commonly used. In flood-prone areas, houses may be built on poles or stilts (e.g., bamboo) (see Annex B, Figure #3) driven into the ground to the appropriate depth. Mat footings are sometimes used in unfavorable soils.
Walls: Walls can be either structural or nonstructural elements of a dwelling. Walls often serve as infill for a framed structure, and hence their contribution to the overall structural resistance of a building to wind pressure can be minimal. Structural walls of wood, concrete, burnt clay, or soil-cement composition are the most common in low-cost housing construction. Walls are either monolithic or small unit masonry type (where units are laid in staggered courses, usually in beds of mortar). Clay, brick, tile, adobe brick, and concrete block are the most commonly used masonry units. Quality control in making these units, as well as the mix used for the masonry mortar bed, can be critical to the structural strength of the total wall.
Wind stresses on walls are either out-of-plane bending or in-plane stresses. Out-of-plane pressures (when winds act directly at right angles to a wall) cause deflection and eventually failure. Tornadoes, for example, which are common in Bangladesh, create pressure drops so strong and sudden that walls are actually pulled outwards. In-plane stresses are developed in walls that act as shear resisting elements within a building, the plane being parallel to the wind direction. In this case, incorrectly planned wall openings may be critical, especially at corners. In any case, where two walls intersect, or where walls and foundations or walls and roof meet, special design is required due to the high stresses created at these joints.
Roofs: Roof pitch is an important consideration for good wind resistance. The magnitude of positive or negative wind pressure on roof surfaces is directly related to roof pitch. Wind affects roofs in two ways, direct and indirect. Direct local effects are made up of high positive or negative pressures over local areas of the roof. This pressure may lead to roofing damage to shingles, tiles, corrugated sheets, etc. Overhangs, common for sun protection, are especially liable to wind damage as they undergo positive pressure from below and suction from above.
Indirect effects occur when wind loads are transferred to lateral walls, causing stresses. If these pressures are strong enough, the capacity of connections will be exceeded and the roof will be lifted off. Since every roof has a structural role as a horizontal diaphragm, such pressures bring additional danger. This diaphragm behavior of a roof transmits windloads from the front to the side walls. If a roof is blown off, both frontal and lateral walls may collapse due to loss of diaphragm stiffening. Flat roofs with overhangs are more subject to damage than steep pitch roofs.
The Issue of Stormwater Drainage: An important problem in the reconstruction efforts in Nueva Choluteca is the lack of provision for adequate stormwater drainage. This observation is not to establish or direct blame (many complex issues limit NGO involvement), but it is imperative that careful attention be directed to this particular issue. Experience has shown that this community is vulnerable to heavy rains during the rainy season (August-December) in Choluteca. The soil here is not porous, thereby increasing the likelihood and incidence of flooding. Indeed, during the rainy season in 1999, this reconstruction site was flooded - a crucial indicator of things to come (see Annex B, photos 26 and 27). One and only wonder what another Mitch-scale hurricane may bring. Hopefully, local authorities will soon address this important issue, and an efficient and functional stormwater drainage system will be established.
Disasters clearly draw international funding supporting risk-analyses that incorporate estimates of the probability of various levels of injury and damage and provide a more complete description of the risk due to the full range of possible hazards affecting a given area. Disasters, as detailed below, also draw attention to the state and quality of low-income housing and can influence international as well as national reconstruction funding dealing with housing and disaster mitigation.
As observed by Godschalk, Kaiser, and Berke, sustainability in the predisaster period seeks to avoid "saddling future generations with sprawling wasteful land patterns that not only reduce the social livability and economical viability of the communities but also undermine the ability of the natural environment to absorb natural forces and expose people to significant hazard risks" (Godschalk, pp.85-86).
Mitigation, within this context, is defined as a statement of intent or a plan of action to reduce such significant hazard risks while incorporating sustainable values; this includes seeking opportunities to relocate inappropriate land uses out of hazard areas and to rebuild damaged homes and infrastructure in more resilient ways instead of replicating brittle, unsustainable development practices. Sustainable communities also recognize the interconnectedness of social, economic, and environmental goals, and strive to break down the defacto zoning of urban and rural living space, which has previously resulted in the poor occupying the more hazardous regions in frail dwelling units.
Also, as previously mentioned, during disasters, the frequency of transactions with outside systems often increases. Affected people perceive their value; linkages develop among various government departments and among official and voluntary agencies. This factor, coupled with the sense of urgency that disasters often generate, tends to foster a coordinated and efficient approach to addressing the problems of disaster-prone areas (Bhatlacharya, 1975; Fernandez, 1979 ).
Disasters also collectively motivate people, leading to cooperation for public good and, in some instances, institutionalizing newly experienced power. Another opportunity afforded by a disaster event is the chance to alter the physical development patterns to reduce future hazard vulnerability.
Finally, disasters often lead to a comprehensive survey of vulnerable areas that provides a more complete understanding of the dangers at large, thereby easing the initiation of long-term measures within the context of overall development plans for that area. Support for hazard mitigation is typically strongest in the immediate postdisaster period (Rubin, 1985; Berke, 1992); with appropriate construction, repair, and land-use standards, a rebuilt community can be at lower risk to future disasters, compared to predisaster conditions. Moreover disasters can promote the resolution of long-standing community problems through reconstruction.
Therefore, the conclusions are clear: for mitigation measures to result in sustainable development it is imperative that land-use planning promote the avoidance of high-risk areas, for land-use planning and hazard mitigation are concerned with anticipating tomorrow's needs rather than responding to yesterday's problem. Together they can be powerful tools for reducing the cost of disasters and increasing the sustainability of communities.
Again, although the circumstances can be tragic, disasters do often offer opportunities to develop social resources, and the goal of international agencies should be to strengthen the local capacity to recover and undertake sustainable economic, physical, and social development projects once the recovery is complete.
The Central American governments' treatment of the crisis brought about by Mitch as something new fails to recognize the strong relation between this crisis and the almost permanent internal crisis experienced by the poor in the less-developed regions of Honduras and other countries. Many internal, as well as external, agencies (international organizations, NGOs) have made the mistake of viewing Mitch aid as exclusively addressing hurricane damage and repair and not viewing it as indicating and dealing with the more basic causes of this ongoing social tragedy (Barraclough, 1999).
An important problem that Hurricane Mitch revealed was the weak links between outside NGOs and regional governments. It also showed NGOs the importance of building and strengthening local infrastructure, if their reconstruction was to make a long-term impact. Moreover, for international agencies interested in strengthening community organization, Mitch showed that it was wiser to identify and seek local partnerships, if solutions were to result in sustainable communities.
Below, the reconstruction efforts in Honduras are analyzed using an important set of questions basic to long-term sustainability and growth. These are fundamental questions that any international agency or NGO interested in offering reconstruction aid should address. Although there are no easy answers, the issues can serve as pointers to help an agency determine the consequences of aid on a developing country, particularly with respect to the development of sustainable solutions in the field of housing.
Has the hurricane reconstruction in Choluteca been seen as a vehicle for improving rural building techniques by the international agency involved in the provision of the postdisaster permanent housing?
A careful observation of the practices of the many international agencies and NGOs in Nueva Choluteca shows that, although many NGOs have provided substantially in the form of reconstructed housing, few have actually seen their reconstruction efforts as primarily for improving rural building techniques.
An exception and a noteworthy example is the Spanish Consulate in Choluteca, the Consulidad Espanol, whose reconstruction efforts in Nueva Choluteca began with the establishment of a training school on site that offers courses in carpentry, welding, and construction. This school was planned as a resource and training center for the work generated by the construction of the new housing units.
This center has not only generated local manpower for reconstruction but has also imparted valuable skills to the local people, skills that will hold them in good stead in the future and strengthen their capacity for future construction and reconstruction.
Was the international agency involved with the local framework; were solutions integrated with existing resources and talents?
A study of the construction methods used by Atlas Logistics, Consulidad Espanol, CECI, Bolsa Samaritana, and other NGOs in Nueva Choluteca points to the growing use of local resources and talents in present day relief and reconstruction measures - at least the ones in this region. Atlas Logistics in particular used concrete blocks, cement, wooden frames, and tiles that were locally made, thereby encouraging many small-scale enterprises in the process. CECI also particularly encouraged the use of tera cotta tiles manufactured locally for their reconstructed units, thereby providing business for a great number of small-scale tile manufacturing units.
Although there seems to be a strong emphasis on the use of local resources in present day relief aid, the important issue is not just the use of local resources, but how local manpower can be created. In most developing countries, the challenge is to organize and initiate measures that promote talent-building. With specific reference to Honduras (Choluteca in particular), the need to provide specialized training that mobilizes the youth is of a higher importance than, perhaps, in other countries such as Guatemala and Mexico, where highly trained local resources are more readily available.
How can international reconstruction direct the community toward greater autonomy and self-sufficiency as it struggles with disaster recovery?
Inferring from experiences in postdisaster reconstruction both in Central America and other parts of the world, one can see that the community can be geared towards greater self-sufficiency by:
How can disaster relief be geared toward assisting communities with "their" reconstruction processes?
Both external and internal agencies involved in relief should consider the long-term effects of the aid being offered and view their reconstruction aid as a vehicle that should be integrated with the developmental objectives of the community.
How were past construction techniques technically inadequate (to resist high-wind and other hazard conditions)? What mitigation measures could be incorporated into the disaster relief housing that would render them safe from the onslaughts of subsequent storms and hurricanes?
As discussed previously with regard to appropriate siting, relocation of poor settlements away from vulnerable areas is the most important consideration. Another is to reduce the incidence of poor quality structures close to high-risk areas by relocating sites and services away from vulnerable zones. A third consideration is the integration of special technical measures into house construction - for example, the inclusion of special hurricane fasteners for roof/wall connections, the addition of extra vertical and horizontal reinforcements to deal with lateral and shear stresses, the integration of roof and wall attachments, the raising of the floor level as a precaution against inundation, and the provision of an efficient stormwater drainage system to drain excess water during the monsoon season.
How can international disaster aid fill in the gap between where its reconstruction efforts end and the country's self development begins?
While much disaster relief originates outside the stricken country, planning for preparedness and mitigation must, necessarily, be undertaken within the country, taking into account available resources. This precautionary planning and mitigation should rely heavily on the indigenous resources of the country so that autonomy and self-sufficiency are encouraged.
Therefore, again, the most important goal of international aid agencies should be sustainable solutions within the community and the integration of the agencies' developmental measures with the goals of the local residents.
To sum up, in the words of Oliver-Smith, the success of postdisaster reconstruction is much more than a matter of delivering and constructing houses and towns (Smith, 1989). It is as much a matter of how that work is done. From the analysis of the reconstruction efforts in Nueva Choluteca, it is clear that victims do need significant material assistance, but when the problems are conceptualized as largely economic and technological (that is, in terms of efficiently building dwellings that get people minimally sheltered as quickly as possible), the chances of success are greatly reduced.
On the other hand, where postdisaster reconstruction and resettlement are approached not simply as logistical problems but as sociocultural processes integrating communal living and infrastructure, encouraging the victim populations' participation and involvement, the chances for success are greatly enhanced.
Successful reintegration of a community does not depend upon well-built housing alone. When reconstruction is not seen solely as house building, independent of the construction of related, necessary environmental systems for water, electricity, sewage, security, education, employment, greenery, and sociocommunal living, there is every reason to believe that reconstruction may begin to bridge the gap between where external aid ends and local sustainable development begins.
