Learning Objectives • Introduction to Shelters in Disaster Relief Situations • The need for Architects and Engineers to be involved in the early response to disasters • Explanation and Exploration of the Sphere Standards – Minimum Standards in Shelter and Settlement Developing World Disasters This presentation looks at shelters in a disaster from the perspective of the developing world. When Katrina hit, we looked to the US Government and FEMA to provide shelter. In the developing world, there is no FEMA. Current Concepts in Shelters The Classic Tent What are the Options? • Host Families • Rural Self-Settlement/Urban SelfSettlement • Collective Centers • Self-Settlement Camp • Planned Camp This graph was prepared by the Sheltre Center, Geneva, Switzerland Pakistan Relief Shelter – built by MRDS Tent City in El Salvador Metal Framed – Tarp Clad concept house Super Adobe Homes – Southern Iraq Photo by Reuters/Finbar O’Reilly Photo by AFP/Salah Omar Settlements in Darfur, Sudan eMi Designed Housing for Hurricane Stan Relief – Guatemala Concrete Canvas Concept House (house in a bag) Why do we need Architects and Engineers involved? • Impacts of Early Decisions • Providing Tools to Build Back Better • What steps can we take? From Rick Hill, CHF International Elements to Consider in Siting and Designing a Settlement • Community – Who is the community how does the community function? • Water and Wastewater - What are the advantages of the site? • Hazard Analysis – What caused the disaster and is the new site prone to the same or new hazards? Providing Tools to Build Back Better • “Few tools exist to support communities to ‘build back better’” – Dr. Tom Corsillis, Codirector of the Sheltre Center • The tragic result is that communities often build back worse Pakistan Home Construction Improvements for Earthquake Resistance Pakistan Home Construction Improvements for Earthquake Resistance Keys to Success • Know the Culture/Client • Understand the Building Material, Construction Techniques • Understand and Design to the Sphere Standards • Know the Funding Mechanisms As a design consultant – you have been trained to do this! Most major settlement and shelter decisions are made by country directors and heads of mission, not by technical specialists. What is wrong with Pre-Fabs? • “Pre-fabs are often imported into a disaster area from another country -- and the money needed … goes in the opposite direction. The local/regional economy affected by a disaster is robbed of important capital that could circulate within that economy, thereby aiding in the overall resurgence of that economy.” • “Use of pre-fab units negates an extremely important function of shelter: the need for family, community, social, and cultural expression.” • “When they are introduced into a disaster area, pre-fabs have the effect of undermining the shelter sector standard of output, which can lead to significant and time-consuming discussions among donors and NGOs even before the ‘have-have not’ effects of differential output reach the community level. Quotes from “PRE-FAB” SHELTER: SOME POINTS TO CONSIDER by Charles A. Setchell, USAID/OFDA Just like every design project is different, every disaster is different – different climates, different materials, different people. We need the professional design community to step up in disaster response to provide quality design solutions to the need for shelter. The Sphere Standards The information in the next section is taken from “The Sphere Project: Humanitarian Charter and Minimum Standards in Disaster Response, 2004 Edition” This information is copyright 2004 by The Sphere Project. The Sphere Project Humanitarian Charter and Minimum Standards in Disaster Response • www.sphereproject.org • Goal: ‘To improve the quality of assistance provided to people affected by disasters, and improve the accountability of states and humanitarian agencies to their constituents, their donors and their beneficiaries’ The Sphere Project • Overall handbook structure Sphere Vocabulary • Minimum standards: subjective, general statement that state the minimum level for a given area • Key Indicators: a more specific, often objective level used to provide guidance in meeting the Standard • Guidance Notes: additional information-advice on priority issues, common dilemmas, etc. Why do we need to know the Sphere Standards? • International Community has recognized the standards as a minimum baseline for humanitarian response. • If the organizations we work with desire USAID/OFDA funding, we will need to reference the sphere standards in our application. Shelter Standard 1: Strategic Planning Standard: Existing shelter and settlement solutions are prioritized through the return or hosting of disaster-affected households, and the security, health, safety and well-being of the affected population are ensured. Shelter Standard 1: Strategic Planning Key Indicators: Priority is given to settlements in the following order – site of original dwellings, host community or host family, mass shelters/camps. Risk Assessment – risk from both physical security and natural or man-made hazards is minimized Property Ownership or Land-Use Permission has been obtained before a camp is settled Water/Sanitation and Social Services are available or can be made available Transportation Infrastructure Access to household livelihoods is available (markets, land, etc.) This graph was prepared by the Sheltre Center, Geneva, Switzerland Shelter Standard 2: Physical Planning • Standard: Local physical planning practices are used where possible, enabling safe and secure access to and use of shelters and essential services and facilities, as well as ensuring appropriate privacy and separation between individual household shelters. Shelter Standard 2: Physical Planning Key Indicators: Space Planning takes into account the culture so that the camps are in sizes that can be self-managed Access to water, sanitation, solid waste disposal, and social facilities Self-settled camps are based on a minimum surface area of 45m2 per person. (This area includes household plots, paths, roads, social facilities, sanitation, administration, etc.) Roads and Pathways allow access and emergency evacuation while maintaining security Vector risks are minimized What does 45 m2 per person mean? 1 acre (210’ by 210’) is 4050 m2. Therefore, each acre could hold approximately 90 people. What are Vector Risks? Vectors risks are diseases that are associated with insects and other types of pests. Mostly avoided by limiting standing/stagnant water. Most vulnerable are pregnant or nursing mothers, infants and young children, the elderly, and those already weakened by other sickness or malnutrition. Shelter Standard 3: Covered Living Space • Standard: People have sufficient covered space to provide dignified accommodation. Essential household activities can be satisfactorily undertaken, and livelihood support activities can be pursued as required. Shelter Standard 3: Covered Living Space Key Indicators: The homes have a minimum of 3.5m2 covered area per person. The home allows for safe separation/privacy for males and females and different age groups. There is enough space for essential household activities Livelihood support activities are accomodated when possible What does 3.5 m2 per person mean? A 1000 ft.2 house (approximately 93 m2) could house 26 people! It is critical to know the average family size, types of activities in the house, and cultural implications of different designs in order to be effective. A family of 6 requires a 15ft x 15ft (4.6m x 4.6m) shelter Shelter Standard 4: Design • Standard: The design of the shelter is acceptable to the affected population and provides sufficient thermal comfort, fresh air and protection from the climate to ensure their dignity, health, safety and well-being. Shelter Standard 4: Design Key Indicators: Design is familiar and culturally and socially acceptable Repair of damaged structures or upgrading of initial shelters (emergency shelters) is prioritized If familiar/traditional materials are not to be used, alternative materials are accepted by local population and durable and practical Windows/Openings allow for venting and thermal comfort Access to water/sanitation is considered in the design Health risks are considered (including vector control and material choices) Transitional Shelters “Repair of damaged structures or upgrading of initial shelters (emergency shelters) is prioritized” Oxfam transitional shelter design in Tangalle, Sri Lanka • Something between a tent and a permanent home • Foundations/Slabs are placed with temporary structures on top. The slab can be re-used with a permanent structure • Other materials are used in a temporary fashion, but can be re-used in a permanent structure Shelter Standard 5: Construction • Standard: The construction approach is in accordance with safe local building practices and maximizes local livelihood opportunities. Shelter Standard 5: Construction Key Indicators: Local material and labor are used to the benefit of the local economy and environment Local standards are used in workmanship and materials New or Repaired Buildings are designed to resist future natural hazards Construction allows for easy maintenance of the finished building as well as the possibility of additions or upgrades using local labor and materials The financial side of the construction is ethical, transparent, and accountable “Local material and labor are used to the benefit of the local economy and environment” Re-call the “what’s wrong with Pre-Fabs” slide Using local materials and labor add money back into the economy at a time when it is critical to keep the economy going. Shelter Standard 6: Environmental Impact • Standard: The adverse impact on the environment is minimized by the settling of the disaster-affected households, the material sourcing and construction techniques used. Shelter Standard 6: Environmental Impact Key Indicators: Settlement Camps consider the natural resources available for the population The natural resources are managed to meet short term and long term needs Vegetation is protected where possible If a settlement camp is abandoned, the land is restored to previous state unless otherwise agreed Case Studies • Balakot Earthquake – Build Back Better Ideas in Poonch, India • Hurricane Stan – Permanent Housing in rural Guatemala Balakot Earthquake • Location: Poonch, Kashmir • Scope: Assess structural damage and propose simple reconstruction techniques for mud/stone and masonry buildings • Client: Millennium Relief & Development (Frontiers) • Timeline: ~6 weeks after 2005 Pakistan earthquake Balakot Earthquake, Pakistan Lessons Learned • Good job of having biggest impact (creating design guides as opposed to helping only a handful of home/business owners) • Cultural Understanding played a key role in the success of the team – Ability to interact with local leaders – Ability to get design ideas to the masses – Use of “build back better” diagram as an evangelical tool (including the correct word for the “One God” in Urdu) Hurricane Stan • House Design for Rural Guatemala • Training of locals in a new home construction technology Lessons Learned • Coordinated with local design professionals – originally had a shed roof which the locals said should be changed to gable. Also the design was modified in some places to match local customs and superstitions. • Design was modified – steel studs with insulation to panelized system to reinforced/confined masonry Lessons Learned – New Building Technology Comments • The new technology was used in order to lower costs and speed up construction • New technology can work well when you can control the construction • Local fears must be overcome or they will likely ridicule or sabotage the build Lessons Learned – New Building Technology Comments (cont’d) • The original design with steel studs was very easy for North American teams, but had too many pieces and parts for locals to quickly understand • The panelized system was better for locals, but had limited availability outside of major urban areas • Local materials/technologies made it easy to use local labor (and delegate work), as well as easier to involve the community Lessons Learned – Final Quotes • “I have learned the ‘best’ engineered design is not always the ‘best’ design for the community” • “Many in Guatemala did not accept the USAID shelter because it was temporary and they thought if they accepted it they would never get the permanent house the Government promised – which for most never came anyway.” Any Questions?
