‘Few things motivate me more than to be able to help people solve the puzzle of rainwater in their direct environment. To me, the essence of this puzzle is the compensation of overabundance of water in one season and the shortage in the next. And while this is a fact of life for many people in the world, it mostly affects those who live at subsistence level. Rain is more than water, more than a resource, more than a basic need: it is the stuff that makes and breaks landscapes and people. I feel privileged to work with RAIN on rain.’
- Currently finishing a PhD on the history of water development technology and community development in the Kitui district of Kenya;
- Studied cultural anthropology and development sociology;
- Lectured on development anthropology, nature management, political ecology, and gender at several Dutch universities;
- Holds a college diploma in civil engineering and forestry with a specialization in nature management.

‘Spending months in a dry land area during one of my consultancy assignments was a first-hand encounter with the challenges communities face with regard to water availability, access and quality. Having to share a watering point with cattle because other water sources had dried due to drought -as is always the case- yet rains had flooded most of the valleys in the area during the wet season led me to better understand how inadequately rain has been utilized in the region. That provoked me to seek to participate in initiatives aimed at harnessing rain for livelihood improvement. An opportunity to join RAIN as a Project Officer through the YEP Water Programme was more than I could ask for!’

“Everywhere where it rains, we can create water points.”
Abdourahmane Ousmane, Secrétaire Exécutif at Association VDS Burkina Faso.
Abdourahmane Ousmane is Executive Secretary of the Burkinabe NGO VDS (Volontaires pour le Developpement du Sahel), which he established together with his close friend and fellow student Ali Badara Diallo in 2001, making their childhood dream a reality. Since almost 15 years they are successfully accompanying local initiatives to pilot and scale up innovative techniques for a sustainable management of natural resources in Northern Burkina Faso.
From his practical experience Ousmane raises awareness about the potential of RWH for food security in the drought affected Sahel Region of Burkina Faso through:
- articles in local or national newspapers about the environment, rainwater harvesting, food security and water buffer management in the Sahel;
- spreading good practices of RWH at local and regional level through local networks (Local farmers network, Groupe d’apprentissage mis en place avec WaterAid, PNGT – Programme National de la Gestion des Terrains, Cadre de Concertation Regional);
- teaching rural communities, NGOs and development actors about how to link RWH and food security for greatest impact;
- contributing to advocacy initiatives at local, regional and national level to support RWH for food security.

Banzoumana Coulibaly
Banzoumana Coulibaly

“Mali’s development depends on the access to water of the urban and rural population on a permanent basis. The Rain for Food programme provides specific knowledge and specific solutions on how to achieve this”.
Banzoumana Coulibaly is a Young Expert and working as technical advisor for Rainwater Harvesting Capacity Centre / Helvetas, Mali.
Banzoumana, beyond his daily work in the regional Rainwater Harvesting Capacity Centre in Mali, tries to explore engineering possibilities to increase crop production within his country by using the temporarily abundantly available rain. He especially will focus on connecting people and increasing awareness, by organising:
- Lectures for students at the national engineering school ENI.
- Information sessions with government bodies, to explain the importance of the collection of rain water in times of abundance, to provide drinking water for the population in times of scarcity. By giving sound and continuous argumentation to the public and state, he seeks to influence the national strategy for water supply and stimulate the required follow-up by the state.
- Awareness and experience exchange via the online platform rain4food.net and the ‘sharing docs’, ‘wiki’ and Community of Practice functions.

“Water is the source of life and our most precious resource. With its proper management and application through innovative models and technologies, we will create prosperity and a better quality of life for our future generations”.
Carlos is the Country Director of iDE (International Development Enterprise) in Honduras. While iDE focuses on creating income and livelihood opportunities for poor rural households, Carlos has integrated rainwater harvesting into the country office’s day-to-day work. He supports the idea that only with reliable water supply (via rain retention), water can be effectively used (with drip irrigation) to increase household level food, water supply and income (through surplus production).
As a Rain4Food ambassador, Carlos focuses on a variety of activities to scale up this cycle of water and food security – as every drop counts:
- Piloting: currently iDE is constructing a Pilot rainwater harvesting tank of 24m3 capacity in the southern, very dry and rural area of Honduras. The tank will be connected to a drip irrigation and pumping system for agricultural use. To maximize the chance of structurally scaling up, the project is supported and accompanied by the Ministry of Agriculture, large international donor programs and RAIN from the beginning.
- Lobby & advocacy: in front of donor/government agencies, to include the integrated approach.
- Fund raising: participate in calls for proposals, for increased RWH use for crop production, climate change adaptation, resilience building, etc.

“I am strongly convinced that rainwater harvesting is the best way to adapt to climate change and guarantee water and food security in the Andean countries”.
Edwin Rodriguez Valle is Programme Officer at the Andean Network for Rainwater Harvesting, CBC in Peru.
Edwin is setting up and strengthening regional multistakeholder rainwater harvesting networks in the Andean region, including Peru, Colombia, Bolivia and Ecuador. These networks range from implementing NGOs to policy defining institutions. His main goal is to set an enabling institutional and policy environment for rainwater harvesting in the Andean region. Main tasks include:
- Linking and learning; build the internal structure of a regional rainwater harvesting ‘hub’, by exploring connecting and strengthening existing networks/actors.
- Lobby and advocacy.
- Knowledge management and exchange on a global basis.
All of the above to strengthen a regional and trans-regional rainwater harvesting movement.

Alexander Tinti
Alexander Tinti

“Complex problems require complex solutions. RWH through permacultural design and combined with Soil Restoration and Education is the road to sustainable food security.”
Alexander lives in Sri Lanka and strongly supports the concept that:
Contourline Swales combined with the Restoration of Soil Biology is the most efficient way of rural RWH.
Together, these two low-cost-low-tech measurements:
- are applicable on any scale;
- maximize RWH and -storage;
- minimize leaching, evaporation and erosion;
- recharge groundwater;
- restore soil-fertility;
- eliminate the necessity for chemicals;
- and, over time, lead to year-round sustainable food- and crop production.
Alexander currently teaches the system to small-holders and plans to extend it to workshops for villages and larger farming communities.

When we started the www.rainwaterclub.org in circa 1991 we were sure that rainwater would be a huge part of the solution to the water crisis. We have learnt and seen it providing solutions for supplemental water , for safe water in areas of water quality problems, for agriculture as a supplement and the traditional history of water harvesting in india is seeing a renaissance in many modern avatars. Happy to be a part of the global knowledge network to share and learn from all over on rainwater for food.
Vishwanath S. is Advisor at Biome Environmental Trust Banglore in India
Vishwanath lives in India and actively supports the promotion of rainwater harvesting in general. For the Rain for Food programme, he contributes to:
- Promotion and lobbying: to integrate RWH into national water agendas.
- Promote RWH pilots and innovation projects.
- Knowledge Management: identify, create, promote and disperse valuable information and innovations in the sphere of RWH initiatives.
- Personal positioning: create a strong personal exposure and branding, as stepping stone towards creating intended global RWH movement.
