Frequent droughts, heavier rainy seasons and climate change disrupt equilibriums among populations in the South. Many years of experience in different contexts in Africa, Asia and Latin America have demonstrated the effectiveness of rainwater harvesting and the impact of this resource as a vector of resilience.


Our action is based on the implementation of rainwater management projects in developing countries where access to drinking water and exposure to climate change are daily problems, impacting directly and negatively the lives of thousands of women and children.

Our intervention is articulated around 3 components: 1) project implementation, 2) capacity building and 3) support to the development of integrated natural resource management policies.

We offer our partners

> Expertise to plan, develop and build rainwater management systems and to demonstrate the benefits of this resource in an operational manner.

> Decision support tools to provide local decision-makers with the necessary tools for good infrastructure management and to ensure the sustainability of investments.

> Trainings to strengthen the technical and management capacities of local decision-makers, technical services and young professionals (students in civil engineering, architecture, etc.).

> Support for the development of local and regional policies/strategies for water resource conservation and management, in order to strengthen resilience and capacity to adapt to climate change.


Fragilization of ecosystems and people

The fragility of many ecosystems such as forests, hedgerows and mangroves, which act as barriers against the risk of major hazards, increases the vulnerability of communities to the effects of climate change. The loss of soil, the destruction of crops and livelihoods, combined with the accelerated occurrence of these extreme climatic events, impact the resilience and adaptive capacities of communities, fuelling mechanisms of impoverishment.

> Simple ecosystem-based answers exist to sustainably mitigate the effects of intense rainfall events or longer periods of drought.
