Summary of project

Food legumes have a very important role in the lives of people in underdeveloped countries in sub-Saharan Africa and Asia.
The importance of legumes, both nutritious (high in protein) and ecological (regenerative capacity of degraded soils), is well established. In Niger, the most widespread and consumed legume is cowpea. However, with climate change and the advent of extreme climatic conditions cowpeas is no longer sufficient to meet the increasing population demand.

In order to contribute to populations resilience at climate change by increasing the supply of legumes, the researchers thought at alternative adaptation strategies, including crop diversification through the introduction and the evaluation of new cultivated species.
Diversification has the advantage of increasing the nutritional quality of human and animal food and increasing the chances of identifying species and varieties that are much more tolerant of extreme climatic conditions. At the National Institute of Agronomic Research of Niger (INRAN), 215 varieties of so-called orphan or even little known, legumes were tested at the research station in Maradi.

This activity focuses on the evaluation of these climate stress tolerant legumes for potential use in semi-arid production systems in Africa south of the Sahara.


Current Activities:

STOL project is at it’s second year of implementation in Niger. During the first year a trial was carried out with the aim of making an agro-morphological evaluation of some new legume species introduced from India, but are unknown in Niger.

At the end of the first year it was decided to repeat the legumes trial for confirmation of the results in the field. The second evaluation is with 6 legumes : Mung bean, Moth bean, Horse gram, Dolichos, Bambara groundnut and Cowpea.
