Summary of project 

This Trust programme focuses on legumes that are heat and drought tolerant, as may be needed to provide a resilient response to a changing climate. A number of food legumes are grown in arid regions, often on marginal land unsuitable for major crop species. Most are neglected by the major funding agencies. The Trust is exploring the following crops because of their heat and drought tolerant qualities, nutritional value and use by subsistence farmers: horsegram (Macrotyloma uniflorum); moth bean (Vigna aconitifolia); Dolichos (Lablab purpureus); marama bean (Tylosema esculentum); rice bean (Vigna umbellata); bambara groundnut (Vigna subterranea); tepary bean (Phaseolus acutifolius); pigeonpea (Cajanus cajan); lima bean (Phaseolus lunatus); mung bean (Vigna radiata), and cowpea (Vigna unguiculata) and common bean (Phaseolus vulgaris) as check crops.


The Trust’s research goals are to evaluate:

  • the potential benefits of these crops in hotter, drier climates,

  • existing germplasm collections and their accessibility,

  • the need to conserve the crop diversity, and

  • the need for genetic improvement

The intention of the STOL programme is to multiply between fifty and one hundred accessions of each of the crops listed above before providing them to trial sites throughout the hot, dry regions of Africa and India. The field trials in multiple hot / dry locations will then determine which crops have potential to combat the effects of climate change, to provide sources of food, animal feed and to stabilise land against degradation.
