Title: The Contribution of Rainwater Harvesting to Disaster Risk Reduction
1The Contribution of Rainwater Harvesting to
Disaster Risk Reduction
Consultative Meeting on a Global Network of
NGOs UN-ISDR Geneva 25-26 October 2006

Balexert 7-9 1219 Geneva, Switzerland
2Rainwater 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, they had to learn
how to find 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
3Practicing Rainwater Harvesting is valuable under
different disaster conditions
- In areas with heavy tropical rains and prone to
floods
- In arid and semi-arid zones prone to droughts
- 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
5Use of Rainwater Harvesting
- for urban development and natural resources
preservation
- for rural development and food security
6 IRHA The International Rainwater Harvesting
Alliance consists of a network of NGOs with
members in different continents

8A 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
- 16000 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.
