To increase capacity, both regions have a preference for hydropower. Most of the planned new plants will be dependent on areas with similar rainfall patterns and thus multiple plants will experience climate-related disruption concurrently, with considerable impacts for socioeconomic development.<\/p>\n<p>Using analysis of the spatial distribution of rainfall in the regions, as well as climate models and research into the impacts of the 2015\/16 El Ni&ntilde;o event, this policy brief explains the increasing risk of concurrent climate-related disruption to hydropower and provides policy recommendations for overcoming the challenges.<\/p>\n<h3><strong>Key messages<\/strong><\/h3>\n<ul>\n<li>The importance of hydropower is set to grow in many countries in eastern and southern Africa.<\/li>\n<li>An extra 31 GW of hydropower capacity is planned by 2030 to overcome electricity shortages, through 43 large-scale (more than 50 MW) projects.<\/li>\n<li>Around 82% of the new capacity in eastern Africa is planned for the Nile basin, and 89% of southern Africa&rsquo;s for the Zambezi basin.<\/li>\n<li>These concentrations mean that most plants will be subject to similar rainfall patterns and thus will be exposed to similar climate-related disruptions at the same time.<\/li>\n<li>Projected changes in the seasonal distribution and amount of rainfall due to climate change could result in even larger variations.<\/li>\n<li>The negative impacts on generation could have potentially significant knock-on effects through domestic and regional power systems.<\/li>\n<li>This could exacerbate other factors, such as governance challenges, that threaten reliable electricity supply and socioeconomic development in the two regions.<\/li>\n<\/ul>\n<h3><strong>Summary of policy recommendations<\/strong><\/h3>\n<ol>\n<li>Greater recognition of the increasing risk of climate-induced electricity supply disruption is required.<\/li>\n<li>Investment in regional electricity connections should take into account potential climate-related linkages and be designed to minimise the climate-related risks to electricity supply.<\/li>\n<li>Climate change-related rainfall disruptions must be addressed in conjunction with additional planning for climate resilience.<\/li>\n<\/ol>\n<p><strong>Get updates on the Institute&rsquo;s sustainable development work:<\/strong>&nbsp;Sign up via email for information on new publications and forthcoming events on this research theme&nbsp;<a href=\"https:\/\/lseapps.secure.force.com\/form?formid=217844\"><strong>here<\/strong><\/a>.<\/p>\n\n","protected":false},"excerpt":{"rendered":"<!DOCTYPE html PUBLIC \"-\/\/W3C\/\/DTD HTML 4.0 Transitional\/\/EN\" \"http:\/\/www.w3.org\/TR\/REC-html40\/loose.dtd\">\n<?xml encoding=\"UTF-8\"><p>With substantial new hydropower generation planned for eastern and southern Africa, how can risks from rainfall variations and climate change be overcome to ensure reliable supply and socioeconomic development?
