In this book, major issues surrounding importance of water and energy for food security in the United States and India are described representing two extremes in yield, irrigation efficiency, and automation. The farming systems in these two countries face different risks in terms of climatic shifts and systems’ resiliency to handle the shocks. One may have comparative advantage over the other, but both are susceptible. Innovations in irrigation for food and fuel production, improvements in nitrogen and water use efficiency, and rural sociological issues are discussed here. We also look into some of the unintended consequences of high productivity agriculture in terms of surface and ground water quality and impacts on ecosystem services. Finally, we present ways to move forward to meet the food demands in the next half-century in both countries. As the current world population of 7 billion is expected to reach or exceed 10 billion in the next 40 years, there will be significant additional demand for food. A rising middle class and its preference for a meat-based diet also increases the demand for animal feed. This additional food and feed production needs special considerations in water and energy management besides the development of appropriate crop hybrids to withstand future climatic shifts and other environmental factors. A resilient agricultural landscapes will also be needed to withstand climatic fluctuations, disease pressures, etc. While the upper and many middle income countries have made significant improvements in crop yield due to pressurized irrigation and automation in farming systems, the lower income countries are struggling with yield enhancements due to such limitations. The rise in population is expected to be more in Sub-Sharan Africa and Middle East (Low to middle-income countries) where the crop yields are expected to be low.

Groundwater is an indispensable resource in many parts of the world, where it supports domestic water supply, irrigated agriculture and industry. Its increased, and often intensive, use during the last half century has created problems and raised concerns regarding the potential depletion of local aquifers, water quality degradation and various geologic hazards such as land subsidence and sinkholes. This volume includes contributions by experts from several countries who describe different groundwater management practices in their part of the world and discuss measures and actions in response to the challenges associated with the sustainability of groundwater use and the protection of the groundwater environment, as well as the evolution of legal and institutional framework needed for their implementation. It discusses past and present practices and various aspects of the regulatory and legal framework of groundwater management in Japan, China, India, Iran, Australia, the United States, Spain, Denmark, Switzerland and the European Union, and reviews recent efforts to improve the management of transboundary aquifer resources.

In the forty years since the invention of center pivot irrigation, the Nigh Plains aquifer system has been depleted at an astonishing rate. Is the region now in danger of becoming the Great American Desert? In this volume eleven of the most knowledgeable scholars and water professionals in the Great Plains insightfully examine the dilemmas of groundwater use. They address both the technical problems and the politics of water management, providing a badly needed analysis of the implications of large-scale irrigation.

While Kansas, and specifically western Kansas, are known by many to be the backbone of agriculture in our nation, much of that productivity has been built on the heels of the invention and efficiency of irrigation technology. Unfortunately, recharge and replenishment of the High Plains - Ogallala Aquifer has not kept pace with the demands of agricultural production, and current indications state that without the implementation of conservation or management practices that the aquifer in Kansas could be depleted by 2060 (Steward, et al. 2013). The producers of Kansas are committed to long-term solutions to preserve their way of life, espouse their commitment to natural resources and the environment, and ensure the viability of their operations for years to come. This study analyzed the economic impact of a proposed Local Enhanced Management Area (LEMA) for Groundwater Management District (GMD) #4. While there currently is a LEMA in a portion of GMD #4 known as the Sheridan 6 LEMA, the board of GMD #4 has initiated the process to institute a district-wide LEMA that would affect a large portion of the 10-county area of the groundwater management district (Cheyenne, Rawlins, Decatur, Sherman, Thomas, Sheridan, Graham, Wallace, Logan, and Gove Counties). To complete the analysis for the proposed policy change, multiple scenarios were derived using the IMPLAN software. The first model serves as the baseline scenario and provides status quo information on the current irrigated cropping economics of GMD #4. The second scenario assumes that a district-wide LEMA would require a 25% reduction in groundwater use, compared to current irrigation practices. To achieve this reduction in groundwater use, irrigated acreage was reduced by 25% and transitioned to dryland production. For the third and final scenario, an optimal irrigated crop-mix ratio is determined based on the current shift in production as reported by the producers in the Sheridan 6 LEMA. While this scenario does not reduce irrigated acres, it shows the economic gains that can be captured by using less water-intensive crops as part of the crop-mix ratio. The reduction in irrigation is also imbedded in that the acreage in which production is shifted away from is more water intensive towards acreage that is less water-intensive. Due to a reduction in groundwater use for irrigation, the study determined that there is a negative economic impact in relation to employment and total output in the GMD #4 area. There are 173 less individuals employed from the 25% reduction in groundwater use. Additionally, direct output is reduced by $44.6 million and total output is reduced by $60.0 million. This equates to a $194.49 reduction per acre on a per-acre basis. The study further showed that the economic impact could be lessened by the use of a crop-mix shift as evidenced in the current Sheridan 6 LEMA. The assessment of a crop-mix shift decreased the loss of direct output by $12.0 million to $265.0 million and total output by $16.5 million to $357.1 million. On a per-acre basis, this is a reduction of $140.97, or mitigation of $53.52 in loss per acre due to the use of an optimal crop-mix shift. While agricultural production is highly dependent on many factors, it can be universally agreed that the landscape of agriculture would be different if water was not an available resource. It is the hope that this research will provide a starting point for the producers of GMD #4 to have a conversation about the economic costs associated with the implementation of a LEMA, as well as discuss other options and opportunities to make educated, well-informed decisions that are impactful both now and for generations to come.

The depletion of groundwater stocks reduces the flow of economic value and the production of goods from the resource. This dissertation quantifies these effects in the context of the High Plains Aquifer in the central US. One particular challenge in estimating these effects that we overcome is that feedback effects from irrigation behavior affect resource conditions, which creates an endogeneity concern. We also provide new insights on the potential of collective efforts by irrigators to manage the resource. We study how heterogeneity in resource and user characteristics affect their individuals' willingness to support efforts to collectively reduce water use. The first chapter estimates how changes in groundwater stocks affect the returns to agricultural land. We avoid bias from feedback effects by exploiting hydrologic variation in pre-development saturated thickness that was determined by natural processes in previous geological eras. Simulation results reveal that the average annual present value of returns to land are expected to decrease in the High Plains region by $120.6 million in 2050, and by $250.5 million in 2100. The most severe decreases in returns to land are expected to occur in Texas, Kansas, and Colorado. When the initial saturated thickness is less than 70 feet, most of the economic impact (63%) of a decrease in the stock of groundwater occurs through an adjustment in irrigated acreage (extensive margin), while 37% occurs through reduced irrigated rental rates (intensive margin). When saturated thickness is larger, nearly all of the response is at the extensive margin. The second chapter examines how observed differences in the stock of groundwater affect corn production. To account for the endogeneity of groundwater stock, we exploit variation in current saturated thickness due to variation in pre-development saturated thickness. Simulation results reveal that the annual production of corn would decrease by 48.1 million bushels in the north portion of the High Plains Aquifer due to a uniform 10 ft decrease in saturated thickness, whereas the annual production of corn would decrease by 15.7 million bushels in the south. Further, we find that when initial saturated thickness is less than 70 ft, most of the impact on corn production of a decrease in the stock of groundwater occurs through an adjustment in irrigated acres in both the north and the south. When saturated thickness is larger than 70 ft, then the adjustment is mostly through a change in cropping patterns on irrigated land in the south but still through irrigated acres in the north. The third chapter uses unique data obtained from consequential stated preference surveys in Kansas to explore the factors that influence farmers preferred reductions in groundwater use through a water conservation program implemented by a Groundwater Management District. Our results reveal that farmers located in areas where the aquifer is more depleted support larger reductions in groundwater use. But we also find that characteristics of the users matter as much or more than the status of the aquifer in determining support. Opposition to reductions in water use are strongest among farmers who strongly agree that water rights are a private property, landlords and those who irrigate a larger proportion of their farm. Further, we evaluate farmers' preferences for the methods of assigning water allocations. We find that none of the options are preferred by a majority of farmers and there is no clear evidence that aquifer characteristics or observed farmer characteristics are the key factors affecting the probability that a farmer ranks a method as the best option. This makes it difficult for groundwater managers to identify which method is more likely to be considered fair by farmers. Our results are informative for managers of water throughout Kansas, the High Plains and other regions where conserving water resources is a high priority and localized and stakeholder-driven conservation plans could be a solution.
