Project Description

The Global Yield Gap Atlas for targeting sustainable intensification options for smallholders in Sub-Saharan Africa

Providing food and water security for a population expected to exceed 9 billion by 2050 while conserving natural resources requires achieving high(er) and stable yields on every hectare of currently used arable land suitable for intensification. This is especially relevant for Sub-Saharan Africa (SSA), where 80% of the food is currently produced by smallholder farmers and production is not keeping pace with population growth. There are other aspects to food security than production alone (e.g. access, demand, waste,…); efficiently increasing production on existing farmland forms an essential component of the sustainable intensification paradigm. Production systems are extremely diverse in terms of agro-ecological and socio-economic conditions: no ‘silver bullet’ but rather ‘best fit’ approach from a basket of options. Degraded and poorly or non-responsive soils cover large parts of SSA and represent the majority of poor farmers’ fields. There is a need for a robust method to identify soils suitable for sustainable intensification. Suitable = soils that support resource-efficient and cost-effective responses to ‘interventions’ and not prone to degradation under intensified cropping. Improved targeting of climate x soil x cropping systems (including socio-economic) to take agronomic interventions to scale
