This evidence brief explains how Africa RISING is using an intercropping system known as ‘doubled-up’ legume technology using two complimentary grain legumes. Groundnut–pigeon pea intercropping is the most successful doubled-up system thanks to the two crops’ contrasting structures and maturity dates.
Through its research-in-development work on legume–cereal rotations in Tanzania and Malawi, Africa RISING has established that these rotations work better for larger farms, while intercropping targeted at smaller farms ensures crop diversity, while giving an opportunity for legumes to be grown, thereby bringing associated nitrogen-fixation ecological benefits.
Smallholder farmers in Malawi must cope with small farm size, low soil fertility and production risks associated with rainfed agriculture. Integration of legumes into maize-based cropping systems is advocated as a means to increase production of diverse nutrient-dense grains and improve soil fertility.
This newly published infographic which is largely based on Africa RISING program activities in central Malawi helps to visualize what sustainable intensification means in the context of the farming system in the region and how it differs from the typical farmer practice. It also illustrates how the doubled-up legume technology works to ensure a farmer gets “double” legume grain yields and “double” soil fertility benefits from biological nitrogen fixation.
Smallholder farming households in much of sub-Saharan Africa (SSA) are distinctly diverse within and across communities. This infographic seeks to visually explain the different ‘best bet: best fit’ pathways of intensification for contrasting farm categories (typologies).
