LegumeSELECT: Science-driven Evaluation of LEgume Choice for Transformed livelihoods

点击翻译按钮获取中文摘要

Growth in agricultural productivity lags behind population growth in Sub-Saharan Africa (SSA) making the region increasingly food and nutrition insecure. Legumes have great potential to deal with many of the constraints to improve smallholder livelihoods and natural resource status, either in the form of grains for home consumption or sale, fodder for livestock feed, protein for health and nutrition, available soil nutrients, or fuel wood. Finding niches for multi-purpose legumes could help alleviate poverty, increase food security, improve nutrition and enhance natural resource status. However, despite several decades of agricultural research for development, so far there has been only limited uptake of legumes by poorest farming households. We will help redress this by developing an existing decision framework (LegumeCHOICE) aimed at increasing adoption of legumes in these systems. We will combine existing data with data we will generate here on relationships between legume performance (yield, ability to fix nitrogen, efficient use of nutrients and water) and interactions with their environment (such as influencing soil carbon and nitrogen stocks) under different conditions and managements, into an accessible database. This will form a robust LegumeCHOICE tool, that we will test for a range of specific contexts and will embed with ongoing development initiatives. It will help inform smallholder farmers as to which legumes to select based on desired purpose, anticipated performance for their own farm contexts, management and economics. This is an important step towards improving food and nutritional security, reducing poverty, and enhancing the production environment of smallholder farmers and rural populations, in particular women, in SSA.
