This paper takes as its starting point the mainstream projections that in future, global food production will need to increase by another 60–110% by 2050, to keep up with anticipated increases in human population and changes in diet (it should be noted, however, that the need and feasibility of such increases is contested (see), with many arguing that dietary change and waste reduction can reduce the need for production increases (see)).
As the climate changes, and food demand increases, crop varieties suited to these conditions need to be developed. The authors of this paper warn that crops yields around the world could fall within a decade unless action is taken to speed up the introduction of new varieties. They propose three ways to improve matching of maize varieties in Africa to a warmed climate: reduce the BDA (the process of breeding, delivery and adoption), breed under elevated temperatures and act to mitigate climate change.
In this paper, researchers from a range of research institutions investigate the likely ‘transformational adaptations’ that will be necessary over the next century to maintain agricultural yields in sub-Saharan Africa.
Some scientists have suggested that Africa's wet savannahs could be ideal for growing crops needed to meet the growing demand for food and bioenergy. In this paper however, researchers from Princeton University and the CGIAR Research Program on Climate Change, Agriculture and Food Security (CCAFS) warn that farmland conversion of these savannahs will come at a much higher cost than previously thought.
Yet another paper adding to the growing body of evidence that productionist approaches to addressing food security challenges are unlikely to be sufficient (at least not without unacceptable environmental cost). Shifts towards more plant based diets and measures to address food waste are also needed.
The Bioenergy Strategy commits the UK Government to further work to investigate the merits of temporarily flexing or otherwise relaxing biofuels mandates at times of agricultural price pressures. The current paper presents work by Defra analysts to explore some of the potential implications of this idea.
