Dr Barron undertook research in integrated resource management strategies actively incorporating on and off-farm water uses in field to meso-scale watersheds. Of particular interest to this research were the opportunities to enable desirable transformations of livelihoods and production landscapes for sustainable development, in view of uncertainty and complexity of global and local change. This research was in collaboration with project partnerships in Niger, Burkina Faso, Tanzania, Zambia and India. She also led two projects – Volta V1 and Limpopo L1 ‘Targeting and scaling out’ with partners through the CGIAR Challenge Programme Water and Food (2010-2013).
