“…To explore the role of increased agricultural productivity for food security in Africa, we use IFPRI’s IMPACT system of models (Robinson et al, 2015). IMPACT has been used extensively in projecting future agricultural production and demand and changes to food security globally and regionally (Delgado et al, 2001, Nelson et al, 2010, Rosegrant et al, 1999, Rosegrant et al, 2001, Sulser et al, 2011). It has been used to explore alternative agricultural productivity futures (Islam et al, 2016, Rosegrant et al, 2014), including the potential impacts of climate change on agriculture (Ignaciuk and Mason-D'Croz, 2014, Nelson et al, 2010, Sulser et al, 2015).…”
