For the first time, women farmers in the rural villages of Bessassi and Dunkassa, in northern Benin, are able to grow vegetables and fruits during the six month dry season, improving food security and nutrition for themselves and their families. Farmers are also increasing their income by selling excess crops in the market. Now entering its third year, SELF's Solar Market Garden project has proved that solar energy can provide long term solutions to hunger, malnutrition and poverty in developing nations.

Achievements

At Stanford University, the Program on Food Security and the Enironment (FSE) conducted an economic and environmental assessment of our multi-sectoral intervention in Benin, beginning with the pilot phase. FSE published its findings in the Proceedings of the National Academy of Sciences in January 2010. Researchers found that income and nutrition have improved significantly for women and their families since SELF installed three solar irrigation systems in 2007. The study also concluded that SELF's Solar Market Garden is cost-effective and environmentally sustainable. The systems should pay for themselves in approximately 2.3 years; and they are durable, emissions-free, and more economical over time compared with gasoline- or diesel-powered water pumps.

Background

The Kalalé District of Benin is a poor, dry region in the northern part of the country with approximately 100,000 people - none of whom have access to the electric grid. The economy, as in most rural districts, is mainly based on agriculture with more than 95% of the population involved with farming. Despite its great potential, crop production in Kalalé remains weak and easily influenced by natural conditions. There is precious little rainfall during the six-month dry season that runs from November through April each year.

During the dry season, the land of Kalalé is parched and its people are hungry. Malnutrition is widespread, as evidenced by the many children with distended bellies - a telltale sign of kwashiorkor, a condition caused largely by a lack of protein and micronutrients. The most pressing challenge for all the people of Kalalé is having enough food to eat.

Objectives

SELF's involvement in Benin began in 2006 when we were first contacted by Dr. Mamoudou Setamou, a native of Kalalé who had received a Ph.D. in agricultural entomology from the University of Hanover in Germany. Mamoudou, now a Professor at Texas A&M University, had recently participated in a Kalalé district council meeting to explore options for electrifying the region's villages since the national grid would not be extended to this remote part of Benin anytime in the forseeable future.

Believing that solar might answer the needs of his people, Mamoudou turned to SELF for help. Over the next few months, we put together a plan to generate solar electricity for a wide range of end-uses - including schools, health clinics, water pumping systems, street lighting, and wireless Internet access - in each of the 44 villages that comprise Kalalé District.

In terms of priority, however, an on-the-ground needs assessment revealed that the first concern amoung the local communities was food security: to find a way to overcome the endemic lack of water and agricultural produce that comdemns the people of Kalalé to an endless cycle of poverty and poor health.

Solution

To address the problem, SELF approached Professor Dov Pasternak, at the time a leading drip irrigation expert with the International Crops Research Institute for the Semi-Arid Tropics (ICRASAT). Pasternak had developed the "Africa Market Garden" - a simple but highly effective method of using drip irrigation to grow high-value fruits and vegetables on small plots of arid land in the Sahel region of Africa.

Prior to working with SELF, Pasternak used diesel generators to power the water pumps used in his drip irrigation systems. We proposed solar as a more viable alternative, both economically and environmentally. (In a SELF white paper, it is shown that the payback period for solar pumping - as compared with diesel - can be less than two years, and that's at today's diesel prices which are going up , and solar prices which are going down.)

Finally, in November 2007 SELF partnered with Association pour le Developpement conomique Social et Culturel de Kalalé (ADESCA) to launch a remarkable pilot project, installing an innovative solar-powered drip irrigation system to pump water for food crops. SELF engineers developed a 1.2 kW solar electric power supply that provides 100% of the energy for the pump. SELF secured seed funding for the project by emerging as a winner in the 2006 Global Development Marketplace competition, sponsored by the World Bank.

Bob Freling, SELF's executive director, returned to Dunkassa and Bessassi with a French television crew in June 2009 to spend time with the people and film their progress. Bob immediately noticed a difference in the women, who have filled out since his last visit. Not only are the women better fed, but so are the children and the rest of the villagers who now have year-round access to a steady supply of highly nutritious fruits and vegetables.
