Droughts, Flooding, and Water Scarcity in a Changing Climate

Abstract:

Climate change is fundamentally altering global hydrological systems, intensifying the frequency and severity of droughts, floods, and water scarcity. This paper looks into the way these inter related phenomena are changing due to the increasing temperature in the world, change in the pattern of precipitation, and also on how atmospheric moisture increased. The study identifies the interactions between climate variability and water-related extremes through the use of history of climate data and hydrological records as well as case studies of vulnerable regions. The result indicates geographical differences in vulnerability causing the arid and semi-arid regions and low-lying coastal areas to bear the highest risk. These effects are also compounded by the fact that human activities like deforestation, urbanization, and mismanagement of water among other fundamental activities. With the emerging challenges, the paper highlights the necessity of combined water resource management, infrastructure robustness, and flexible policies to address those kinds of challenges. This research can be used to gain further insight on the concept on water security in the global warming world and in making appropriate decisions to adapt to climatic changes.
