Water resources availability for agriculture use has decreased in recent past due to competition from various water sectors. Dryland agriculture contributes significantly to global food production. Climate change has impacted the availability and distribution of water resources, as well as the productivity and sustainability of dryland agriculture. In the current chapter, various aspects of water harvesting techniques, viz., in-situ and ex-situ, conventional and modern technique have been discussed. Furthermore, significance of supplemental irrigation in dryland agriculture to mitigate detrimental impact of climate change on land and water productivity has been described. Water harvesting and supplemental irrigation techniques have enormous potential to increase crop yield and could be critical measures for climate change-resilient agriculture. Hence, adoption of water conservation measures in dryland agriculture system is necessary to ensure sustainable development growth.
