Support Development one drop at a time

IRHA's 16 years of experience in the complex, dynamic, socio-environmental settings of countries including Senegal, Ghana, Benin, Mexico, Bolivia, and Nepal have demonstrated the efficiency of rainwater harvesting to ensure community resilience in developing countries.


Our on-the-ground action involves implementing rainwater management systems in developing countries, where access to drinking water and vulnerability to extreme weather events are daily problems.

Our interventions adopt a three-pronged approach to improve people's security: running projects, capacity building, and developing integrated natural resources management practices.

We offer local governments and communities:

  • Expertise to plan, develop, and build rainwater harvesting systems
  • Tools for decision-makers, to ensure the proper management and durability of investments.
  • Training, to enhance the technical and management capacities of local decision-makers and technicians.
  • Support for the development of local and regional strategies for the conservation and management of water resources, community resilience and adaptation to climate change.
