Mancosu, Noemi, Richard L. Snyder, Gavriill Kyriakakis, and Donatella Spano. “Water Scarcity and Future Challenges for Food Production.” Water 7.3(2015): 975-992. Print.
In this study, Mancosu, Synder, Kyriakakis, and Spano explore the magnitude of water shortage problem in the world and how it affects global agricultural systems. The main aim of the authors is to show the connection between water scarcity and food security in any country to understand how water resources can be conserved in order to improve agricultural production.
The authors document a number of findings. First, they use statistics from leading global organizations such as the United Nations (UN), the Food and Agricultural Organization (FAO), and others to prove water scarcity in the world. Second, they document the unraveling scenario where irrigation is becoming the mainstay method of food production and competing for water with other sectors of the economy. Lastly, the authors find that there is a close relationship between water possessions of a given country and the capacity to produce enough food for their population.
