Seminar on food security on World Water Week, Stockholm

August 2008 | Sweden

Improve Food Security – Combine Productive Sanitation, Conservation Agriculture and Water Harvesting (Sunday 17 August - Afternoon Seminar)

(Content taken from the World Water Week website)

Convenors: Food and Agriculture Organization of the United Nations (FAO), German Agency for Technical Cooperation (GTZ), International Fund for Agricultural Development (IFAD), International Centre for Soil Fertility and Agricultural Development (IFDC), International Water Management Institute (IWMI), Stockholm Environment Institute (SEI), Swedish University of Agricultural Sciences (SLU), United Nations Convention to Combat Desertifi cation (UNCCD) and Sustainable Sanitation Alliance (SuSanA)


Event summary and Conclusions

All speakers presented arguments why combining productive sanitation with rain water harvesting and conservation agriculture will give large synergies. This combination of good management practices has not been tried at large scale yet, but many of us left the seminar with the intention of implementing this combination.

Honorary Jennipher Byakatonda, Minister of State for Water, Uganda, shared her experience from southwestern Uganda, where they know that the fertilizing effect of urine is large. Yield increase is three times. Director Maimbu Malesu continued that the World Agroforestry Centre, ICRAF, is working on rain water harvesting, productive sanitation and conservation agriculture in different projects. ICRAF now wants to combine these features. Laurent Stravato informed that IFAD, in cooperation with CREPA and SEI, will investigate the impact of productive sanitation on the agricultural productivity and livelihood of poor households in Niger.

Executive Secretary Luc Gnacadja, UNCCD, pointed out that the geography of hunger and poverty coincides with that of degraded lands and that degraded lands fixates less carbon. To improve livelihoods in Sub Saharan Africa we have to improve, not degrade, the land. Simultaneously this will counteract climate change. Professor Rattan Lal, State University of Ohio, continued by comparing soil to a bank account. If you take out more than you put in, the productivity goes down. The soil is degraded, and not even an elite variety crop will yield well. To improve the soil, you have to put more in than you take out.

Dr. Moussa Bonzi, CREPA, pointed at productive sanitation as a way of putting more into the soil. He shared with us the excellent yields which urine fertilized crops produced in their experiments. Often their yields were better than that of urea fertilized crops. The urine fertilized crops were also well accepted by the consumers, Dr. Bonzi responded to a direct question.
