The influence of water, land, energy and soil-nutrient resource interactions on the food system in Uganda

Food Security continues to be elusive in Sub-Saharan Africa (SSA), several decades after the first World Food Summit in 1974. The causes of food insecurity in Sub-Saharan Africa include among others; poverty, economic constraints, agricultural and agronomical challenges, rapid population growth, and the effects of adverse climate change. These causes however, are linked to complex interactions, constraints and dependencies amongst the key physical resources in food systems, namely – Water, Land, Energy and Soil Nutrients (WLEN). There is limited insight on the combined impacts of the resource nexus, and how this may constrain the performance of food systems in Sub-Saharan Africa. This understanding is essential if the food challenges in the region are to be tackled sustainably.
