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.

Prior to this appointment, he was a professor in the Department of Civil & Environmental Engineering and Interim Director of the Water Resources Research Center at the University of Hawaii in Honolulu, Hawaii. He received his Ph.D. in Civil Engineering from the University of Illinois at Urbana-Champaign and M.S. in Civil Engineering from Texas Tech University. He served as a staff engineer with the consulting firm Geraghty & Miller, Inc. (now part of Arcadis Geraghty & Miller) in Hackensack, New Jersey between his two graduate degrees. Additionally, he was employed as a research associate and associate scientist at the Illinois State Water Survey in Champaign, Illinois. His research interests are in the areas of water and chemical movement in soil and ground water system, water for food production, riverbank filtration for water supply, and general water quality. He is a registered Professional Civil Engineer in Illinois and fellow of the American Society of Civil Engineers. He has published/edited nine books, over 100 peer-reviewed journal papers, many technical reports. He has made dozens of presentations in the areas of water quality, contaminant transport, and riverbank filtration.
Sekhar Muddu, Ph.D. is a Professor with the Department of Civil Engineering, Indian Institute of Science, Bangalore, India. Currently, he is also adjunct professor at Nebraska Water Centre of the University of Nebraska Lincoln, USA. Additionally, he is the coordinator of the Indo-French Cell for Water Sciences at Indian Institute of Science. He received his Ph.D. degree from the Indian Institute of Science, Bangalore, India in the area of hydrology & water resources. His chief research interests are in the areas of groundwater systems, agro-hydrology and satellite hydrology. He has published over 100 peer-reviewed journal papers and several technical reports. His significant effort was pioneering installation of the Kabini Critical Zone Observatory in India for carrying out advances in multidisciplinary catchment hydrology science in tropical ecosystems of forested and agriculture dominated systems.
Sudhirendar Sharma, Ph.D., formerly with the Water & Sanitation Program of the World Bank and currently a Senior Consultant with the World Bank, Dr Sudhirendar Sharma has been a committed student of water science, a keen observer on climate change dynamics, and a critic of the contemporary development processes. With a masters degree in soil chemistry from Himachal Agriculture University and a doctorate in environment science from Jawaharlal Nehru University, Sharma has had decades of experience working with non-governmental organizations, media outfits and multilateral institutions. Given his varied but inter-connected experiences, his research aptitude in the field of strategic planning, knowledge management and project evaluation have been availed by leading development institutions like the World Bank, DFID, EU, IDRC, IFAD, GIS and the like. He has published extensively in national and international journals and magazines. Over the years, Sharma has diversified himself as a quasi-academic researcher, a development analyst and a specialized consultant. For him, this is a form of ‘evolving entrepreneurship’ that helps him keep growing with changing times. Sharma is based in New Delhi.
