The Intergovernmental Panel on Climate Change anticipates a global mean surface temperature increase of 2.0 - 4.5ºC by the year 2100, a consequence of rising atmospheric carbon dioxide levels. Climate variability is also expected to intensify, bringing with it unpredictable monsoon patterns and a greater frequency of extreme weather events, including more intense droughts and floods. These environmental shifts are understood to impact every facet of the hydrological cycle. Consequently, this could disrupt the equilibrium between food demand and supply across various regions of the globe, both temporally and spatially. South Asia and Africa are projected to be especially susceptible to these environmental shifts, given their substantial populations, reliance on agriculture, and constrained resource availability. To safeguard future water and food supplies, a heightened focus on climate change adaptations is essential. This necessitates, among other measures, increased investment in adaptation and mitigation research, the refinement of land use and natural resource management policies, and enhanced risk management strategies, including early warning systems and crop insurance programs.
