The Contribution of Rainwater Harvesting to Disaster Risk Reduction

1. The Contribution of Rainwater Harvesting to Disaster Risk Reduction Consultative Meeting on a “Global Network of NGOs” UN-ISDR Geneva 25-26 October 2006 IRHA International Environment House 2 Chemin de Balexert 7-9 1219 Geneva, Switzerland

2. Rainwater Harvesting is one of the most ancient activities in the history of mankind Human beings have always sought to settle near water Whether in dry or wet areas,theyhad to learn how tofind and save water as it is a limited resource Human beings learnt to meticulously harvest every raindrop Build simple constructions to store the collected rain and use it rationally

3. Practicing Rainwater Harvesting is valuable under different disaster conditions • In arid and semi-arid zones prone to droughts • In areas with heavy tropical rains and prone to floods • An appropriate rainwater management is necessary for the protection of the ecosystems

4. The two « hazards » - flood and drought should be integrated into a wider risk management system

5. Use of Rainwater Harvesting • for urban development and natural resources preservation • for rural development and food security • for disaster reduction

6. IRHA – The International Rainwater Harvesting Alliance consists of a network of NGOs with members in different continents • IRHA Members’ Focus areas : • Household and productive uses; 2.

8. A Community Based Initiative: Rainwater Harvesting in the Municipality of San Antonio de Lomerio, Bolivia Objectives: • Reduce the vulnerability of the population towards the shortage of water by improving the infrastructure • Capacity Building (Environmental Education and training of RWH managers) Duration: • September 2005 to October 2006 Funding Source: • Service de Solidarité et de Coopération du Canton de Genève Budget of the Project: • 16’000 USD Partners: • Green Cross International and American Peace Corps

9. Construction of Water Tanks The goal is to construct 25 water tanks of 10m3 each At the end of August 2006, 21 reservoirs had already been constructed

10. Capacity Building of 15 community members Along with the construction of the water tanks, 15 community members were trained on how to construct them. In this case sustainability could be reached after the project was finalised. This also contributed to the empowerment of community members Another result of that was to train 15 rainwater harvesting managers

11. Training Workshops • The resilience of community members was a result of: • Decreasing the number of skin and gastro-intestinal deseases; • Stressing the importance of hygiene to the health and well being of the population; • Focusing on the importance of environmental preservation; • Introducing the Swiss system of purification of water « SODIS » • All of these factors contributed to disaster risk reduction

12. Impact of RWH on Disaster Reduction: • In the case of a drought, assured access to drinking water and enlarged possibilities for yielding crops; • Avoids the danger of gastro-intestinal epidemies and diminishes child mortality because of improved hygiene; • Assures water reserves for fire protection; • In case it is practiced on a larger scale, it contributes to flood reduction; • In post-disaster conditions, offers the only clean water; • Benefits not only human beings but the environment in general.
