With countries revisiting their climate pledges agreed at the conference of parties (COP) in Paris in 2015, the discussion on the impact of changes in the long term climate has never been more relevant. Specifically, since the 2011 Bonn conference on the nexus between resource systems, the interlinkages between energy, water and land resource systems and their climatic connections are on the radar. Despite the excitement around the nexus between the climate, land, energy and water (CLEW) systems, they are still explored in isolation in many countries. This has resulted in lopsided policies, making long-term infrastructure investments vulnerable to climatic changes. This dissertation, taking the case of the Eastern African region, adds to this discussion on resource interactions, sectorial policy decisions and climate resilience.
