Small Grants Programme: Analysing the economic development impact of semi-arid lands, and mitigation through food-trade water resource decoupling

What is the relationship between semi-arid lands and national economic development, and the potential of food/agricultural trade to buffer semi-arid land vulnerability and mitigate water scarcity? Should investments be targeted directly at semi-arid lands, or should wider national institutional and capacity considerations be given more attention as a means of mitigating vulnerability?
