Africa: Investing in People and Evidence for Sustainable Farming

Evaluation of farming systems, new ideas and learning with practitioners should be part of a transformed agriculture.
Food security is difficult to pin down. It can be explained simply as access to enough food. But behind that simplicity lies an interconnected web of factors – from food prices to agricultural practices, nutrition, natural resources, technology, trade and social development.
Breaking down such complexity to its component parts is artificial, but is often necessary to gain understanding. It is in that spirit that the collection of articles this week focuses on just one, but fundamental, aspect of food security: sustainable agriculture. We examine how science and technology (S&T) can increase agricultural productivity within environmental and resource limits. (Our next Spotlight will explore other aspects of food security.)
Although agricultural productivity has changed remarkably over the past 50 years or so, partly helped by advances in S&T, the limits to this growth are now clear.
