Uganda faces challenges in agricultural sustainability due to climate variability and increasing population pressure on limited arable land. A comprehensive review of peer-reviewed articles, conference proceedings, and grey literature focusing on case studies from various regions of Uganda. Integration of livestock with crops showed an average increase of 10% in crop yields in semi-arid areas compared to non-integrated systems. The reviewed evidence supports the potential of integrated livestock-cropping systems for improving farm sustainability and food security across different ecological settings in Uganda. Policy makers should promote agro-ecological zoning and extension services tailored to specific regional conditions to maximise benefits from these practices.
