A Review of the Impact of Climate Change on Water and Food Security Concepts
Keywords:
Climate Change; Food Security; Water Security; GCMs.Abstract
Water scarcity is now a major obstacle to social and economic progress and a threat to survival in more regions of the world, there has been an urgent need to study the effects of water shortages and their impact on human security, which is directly related to water and food security. This article deals with the basic concepts and dimensions of water and food security and highlights the most important findings through local and international research and reports. On the other hand, climate change is the main component of the index for assessing water and food security in the long term, and this is manifested through increasing annual temperatures and fluctuating amounts of precipitation. In addition, the increase in population numbers and the industrial sector reduce the quantity and quality of water in the region under complex climatic conditions. There is already ample evidence of the projected effects of climate change on important agricultural crops. Globally, positive outcomes are less common than negative outcomes. The results obtained about the effects of climate change on agricultural production indicate that climate change has a significant impact on wheat and maize crops in a number of locations. Water security is designed to safeguard all aspects of water, from our everyday water use to water in our ecosystems, to even political and transboundary conflicts that may arise over water. Water security is critical to achieving sustainable and comprehensive growth.
