1. Climate Change Mitigation (protecting the environment)2. Climate Change Adaptation (protection from the environment) Karen Walker, ProAct Network Martin Suvatne, Shelter Adviser, Norwegian Refugee Council (NRC)
EXAMPLE Burundi – NRC shelter solutions 1.Climate Change Mitigation (protecting the environment)
NRC Shelter Program Burundi • Reintegration of Burundian returnees from Tanzania, • Protection of Congolese refugees in camps since 1997 • > 13,000 Shelters focus on ownership and responsibility • > 200 permanent and 600 semi-permanent classrooms • Study on improvements or possible alternatives for the use of materials with limited adverse environmental impact
Typical solutions for returnees • NRC Shelter Policy: • Integrate environmentally friendly materials and appropriate technology
Temporary Schools Timber frame + plastic sheeting walls + corrugated iron roof Cost : USD 1,300 Lifespan : up to 5 yrs
Semi-permanent Schools Cement block windows Cost : USD 3,500 Lifespan: 15 to 20 years • Adobe structure on hardcore foundation • Reinforced concrete columns • Timber frame + corrugated iron roof
Permanent Schools Reinforced concrete structure completed with fired bricks Metallic frame and corrugated iron roof Cost USD 12,000
Environmental Impact • Key considerations : • Adobe bricks : where from? topsoil reuse? safety of pits? • Fired bricks : where from? type of kiln? efficiency and wood use? • Hardcore, gravel : source? sensitive area? • Timber : source? type of wood? certified? • Iron sheeting : source? transport? • Local purchase vs. import and transport • Environmental checklist
Conclusion • Knowledge of suppliers and material sources • Appropriate designs developed with local communities and • technicians • Awareness of key environmental impacts (simple checklist) • Simple, local measures can ensure that NRC reduces its • contribution to the global problem (a bit at least)
Wood Distribution, Use and Management Wood distribution
Wood Distribution, Use and Management Charcoal production
Cooking Practices and Stoves Traditional 3 stone fire Improved mud stove Locally made charcoal stove
Briquettes: “Tabarigiti” • Made in Bujumbura from • 50% coffee husk • 20% rice husk • 15% cotton husk • 10% cow dung • 5% wood chips • Common complaints: slow lighting • excessive smoke inefficient
Firewood Use – Main Issues • Evidence of excessive wood distribution - charcoal production • Supplier certificates may be fake • Low awareness and knowledge of fuel-efficient cooking techniques • Food types such as beans increase cooking time and wood consumption • Adding insulation to shelters would reduce wood consumption for heating • Lack of baselinedata on surrounding forestry resources and management
Risk Analysis and Cost-Benefit Analysis 2. Climate Change Adaptation (protection from the environment)
RISK ANALYSIS Source: GTZ, Toolkit Disaster Risk Management, Eschborn 2006
RISK ANALYSIS • Institutional characteristics: technical and financial capacities, responsibilities, roles, • Legal frameworks, norms, laws, human rights, • Politics, corruption, power and property structures, • Poverty, • Risk and protectionperception, local wisdom, • Education, social organizations (NGOs), access to information, • Gender aspects, minorities, old and young people, • Usable soil, soil stability • Usable water, • Vegetation, biodiversity, forests, resource degradation, • Stability of the ecosystems. Source: GTZ, Toolkit Disaster Risk Management, Eschborn 2006
RISK ANALYSIS • Technical construction method/quality of settlements and buildings, • Basic infrastructure (transport, energy, communications, water), • Population growth and density, age structure. • Socioeconomic status, income and economic structure, • Land use, technology and agricultural cultivation structure, • Access to resources and services (water, energy, health, transport) • Reserves and financing opportunities; • Incentive or enforcement systems for prevention and mitigation, Source: GTZ, Toolkit Disaster Risk Management, Eschborn 2006

COST-BENEFIT ANALYSIS Major weather-induced natural disasters, 1950 –2002 (source: Münchener Rück - Munich Re)
COST-BENEFIT ANALYSIS Encompasses calculation of the probability that a natural event will occur at a given location with a certain intensity; what can happen and how often? The degree of destruction – from the humanitarian, economic and ecological perspectives – as a function of the intensity of the event; how severe will it be? Source: GTZ, Toolkit Disaster Risk Management, Eschborn 2006
COST-BENEFIT ANALYSIS The combination of hazard and vulnerability functions yields the risk; the probability that damage will occur on a certain scale; how big will the damage be? The costs of risk reduction result from the construction and maintenance costs for an infrastructural measures and humanresources development; how much would it cost to prevent destruction? Source: GTZ, Toolkit Disaster Risk Management, Eschborn 2006
COST-BENEFIT ANALYSIS the originalloss-frequencycurve, generated without risk-reducing measures, is compared with the loss-frequency curvewith risk reduction. what seems cheaper, prevention or pay the damage? The total netbenefit of a project is determined by extrapolatingthe benefits calculated in step 5 onto the lifespan of the project. The total costs for preventive measures, and maintenance costs, are then subtracted from this value. what is cheaper in the long run? Source: GTZ, Toolkit Disaster Risk Management, Eschborn 2006
COST-BENEFIT ANALYSIS Methods to determine the net benefit of projects: • A probabilistic approach, which calculates the risk on the basis of a detailed analysis of hazard and vulnerability. • A damage-based approach, which takes damage caused by past events as a basis for calculating the present and future risk.

1.Climate Change Reduction (protecting the environment)2. Climate Change Adaptation (protection from the environment) • Discussion Points: • What do we know about the impact of the changed climate on shelter? • What do we have to do different with our shelter? • What does it cost to build different shelter and neigbourhoods? • What does climate change mitigation mean to us? • What does climate change adaptation mean to us?
