Under a scenario of continuing high population growth and regional disparities in income, an additional 550 million people globally could be at risk of climate-related hunger by 2080, with 65 per cent of this increase occurring in Africa (Parry et al., 2009). There are key post-harvest elements of food availability, stability, access and utilisation. For example, maintaining high quality and sufficient stocks of stored grain enables a household (or a nation) to provide itself with a nutritional and safe supply of food until the next harvest. Given that the market value of grain typically increases up until the next harvest, grain stocks also provide a market-linked asset, part of which can be sold if needed to cover income shocks or emergencies.

Post-harvest impacts of climate change

Five key climate change trends affecting different parts of SSA were identified:

  • a general increase in temperature;
  • more frequent occurrence of dry spells and droughts;
  • more frequent occurrence of high winds, storms, heavy precipitation events and flooding;
  • more erratic rainfall;
