The concept of 'development corridors' is increasingly used to support economic growth in Africa, driven by international as well as national interests. Development corridors have tremendous development potential yet they face significant challenges. These include uneven development impacts, traversing so-called "underutilised" lands that are generally already populated and managed, and vulnerability to climate change. Such challenges result in a lack of appropriate research capacity in the region. This proposal aims to addresses these challenges through engagement with decision makers and by developing relevant capacity within research institutions and researchers in eastern Africa, China and the UK. The research is targeted to generate decision-relevant evidence and feed it into key decision making processes in order to improve the sustainable development outcomes of investments in development corridors. The proposal is focused on corridors in eastern Africa, particularly the Southern Agricultural Growth Corridor of Tanzania (SAGCOT) and the Lamu Port and Lamu-Southern Sudan-Ethiopia Transport Corridor (LAPSSET) in Kenya. The consortium is led by the United Nations Environment Programme-World Conservation Monitoring Centre (UNEP-WCMC), who would be contracted as 'WCMC', and comprises five universities (Cambridge, London School of Economics, Nairobi, Sokoine University of Agriculture and York) and three boundary agents (World-Wide Fund for Nature (Tanzania), African Conservation Centre (ACC) and the China National Centre for Climate Change Strategy and International Cooperation (NCSC) of the National Development and Reform Commission (NDRC). The work is structured around three outcomes and six Work Packages, fully integrating research and capacity development, and significant policy engagement and outreach.
