The Challenge

The Food Sovereignty Platform (PSA) is a working group of 15 Geneva NGOs within the Fédération genevoise de coopération (FGC). Several of its members told IRHA that their projects suffer from a lack of water. Floods, droughts, soil loss and falling groundwater make this worse. Rainwater is a practical answer, but teams often lack know-how and contacts with specialists.

What We Do

  • We presented the idea to PSA members on 10 May 2023 and mapped their needs with a survey.
  • We connect PSA members with IRHA Alliance partners who work on similar themes or in the same regions.
  • With ASGEP, we held a knowledge-sharing workshop in Djilor Djidiack, Senegal, on 15–16 April 2024: theory, shared experience and field visits to calabash tanks and market gardens.
  • We hosted an FGC "café-débat" in Geneva in May 2024 on rainwater in project design.
  • We ran four capacity-building webinars in 2024, including "Beyond plastic tanks!" (June) and "900 students, 1 school, no water!" (September). Speakers came from Sri Lanka, Nepal, Uganda, South Korea and Madagascar.

Results

Progress so far: – After the Senegal workshop, the director of the Keur Yaakar hotel complex, a partner of the NGO Tereo, decided to install a rainwater storage tarp to secure drinking water for guests. – Two target projects were identified early: Graine de Baobab (Burkina Faso) and Tourism for Help (Senegal). – The second webinar reached participants from Bangladesh, Sri Lanka, Nepal, Malawi, Tanzania and other countries. – Other FGC members, such as Enfants du Monde and Terre des Hommes (Colombia), have asked IRHA for advice.

Expected results: – More PSA projects plan rainwater harvesting from the start. – Lasting links between Geneva NGOs and rainwater specialists.
