African Water Footprints and the Challenge of Sustainable Agriculture
As outlined in my introductory post last week, water is a critical resource that is needed to facilitate agricultural production. However, there are significant environmental challenges facing African nations (and the rest of the world) in sustainably meeting its food and water needs, with 4 billion people globally facing severe water scarcity for at least a month each year ( Mekonnen, 2016 ). As many countries see rapid urbanisation and a resulting increased, concentrated demand for food supplies, intensive irrigated agriculture is often seen as a necessary alternative to small-scale subsistence farming. This post will explore the environmental challenges and opportunities in sustainable agriculture through the lens of Dr. Mesfin Mekonnen's work on sustainable agriculture in Kenya.
