Contribution to the Pan African Bean Research Alliance PABRA The greatest global challenge today is how to ensure food and nutrition security of a rapidly growing human population, considering climate change and without adversely affecting the natural base upon which the production is dependent. Beans, as the most important consumed grain legume, are a very good source of vitamins, minerals, and plant derived micronutrients. Significant yield increase of more than 60% are possible, following access to and use of improved varieties coupled with integrated crop management practices.
