Climate Change Impacts on Water Resources and Implications for Agricultural Management

Water supplies are severely impacted by climate change, providing serious problems for agricultural management and food security. Water availability is changing as a result of changed patterns of precipitation, more frequent droughts, and higher evaporation rates, which has an effect on crop growth and yield potential. Water shortage becomes greater by glacier retreat and sea level rise, particularly in coastal and glacier-fed areas. The sustainability of agricultural practices is at risk by these changes, which affect existing water supply channels. Adaptive agriculture management techniques need to be implemented for managing these issues. The concentration on water-efficient irrigation techniques, like drip and sprinkler systems, together with rainwater gathering improving the water use efficiency and improves crop water availability. A variety of cropping methods, enhanced soil health management, and the selection of climate- and drought-resistant crop types all contribute to increased climate resilience. Furthermore, stakeholders can effectively predict and respond to threats correlated to climate change according to integrated water resource management and advance alerting systems. To maintain sustainable water management in agriculture, this chapter highlights the need of implementing adaptive techniques into use. Stakeholders may reduce the effects of climate change, increase food production, and increase the resilience of agricultural systems in facing the challenges of a changing climate by adopting these practices.
