Adapting to the amplification of climate extremes through freshwater capture: evidence from the tropics

In low-income countries of the tropics undergoing rapid growth, global warming presents challenges to the expansion and sustainability of water supplies required to advance progress toward the United Nations’ Sustainable Development Goals. Substantial uncertainty persists in projections of precipitation under climate change. A widely observed impact, pronounced in the tropics, is the intensification of precipitation comprising a transition towards fewer but heavier rainfalls. How does this transition impact terrestrial water balances? How might these changes influence freshwater demand? I will interrogate these questions and review mounting empirical evidence from the tropics of the resilience to climate change of groundwater resources, which act as a natural inter-annual store of freshwater supporting adaptation to the amplification climate extremes. Presented evidence includes case studies and local-to-regional scale analyses from tropical Africa and South Asia. Outcomes emphasize the interconnected nature of surface water and groundwater as well as the value of groundwater as a natural, distributed store of freshwater. This insight provides a platform to explore more equitable and sustainable water development pathways resilient to climate change. Richard Taylor is a Professor of Hydrogeology at University College London in the UK and an Adjunct Professor of Hydrogeology at Makerere University, Uganda. For over two decades, he has worked with researchers, practitioners and stakeholders across tropical Africa and South Asia to inform strategies to expand and sustain equitable access to safe water for drinking and food production. Richard has led and leads large transdisciplinary consortia (GroFutures, AfriWatSan, CLARITY) engaged in needs-driven and solutions-oriented research that also seeks to strengthen individual and institutional capacities. He is the recipient of a Senior Fellowship from The Royal Society and a Contributing Author to two chapters of the 6th Assessment Report of the Inter-governmental Panel on Climate Change (IPCC), Changing Water Cycle (WGI) and Africa (WGII).
