Water scarcity impacts on global food production
2019
Dinar, Ariel | Tieu, Amanda | Huynh, Helen
In this review paper we focus on the dilemma of whether or not current fresh water supply will meet the demand/needs of agricultural crops despite the continuing impact of water scarcity. In addition, we evaluate whether an increase in future population, change in water demand and supply patterns, due to climate change, will allow sustainable food production. With increased scarcity of freshwater, new water conservation technologies and biotechnology were developed, as well as newly developed water sources such as recycled wastewater, and various water institutions, which may help ease water scarcity. With new advancements in farming practices and crop innovations global food supply is still challenged by climate change effects on both water and land resources used for food production.
