Environmental Engineering for the 21st Century


Book Description

Environmental engineers support the well-being of people and the planet in areas where the two intersect. Over the decades the field has improved countless lives through innovative systems for delivering water, treating waste, and preventing and remediating pollution in air, water, and soil. These achievements are a testament to the multidisciplinary, pragmatic, systems-oriented approach that characterizes environmental engineering. Environmental Engineering for the 21st Century: Addressing Grand Challenges outlines the crucial role for environmental engineers in this period of dramatic growth and change. The report identifies five pressing challenges of the 21st century that environmental engineers are uniquely poised to help advance: sustainably supply food, water, and energy; curb climate change and adapt to its impacts; design a future without pollution and waste; create efficient, healthy, resilient cities; and foster informed decisions and actions.




Food, Energy, and Society


Book Description

Since the publication of the first edition of Food, Energy, and Society, the world's natural resources have become even more diminished due to the rapid expansion of the global human population. We are faced with dwindling food supplies in certain geographic areas, increasing pressure on energy resources, and the imminent extinction of many




The Politics of Global Resources


Book Description

Harf begins with a description of the historical patterns and the contemporary character of the international system and shows why it is difficult for the world community to address today's issues. He provides essential information on four specific issues used as case studies--food, actors, energy values, population policy and environment futures; and summarizes how far the global community has solved these issues and what tasks remain.

The Food-Energy-Water Nexus


Book Description

This will be the first textbook on the integration of food, energy and water systems (FEWS). In recent years, the world has seen a dramatic rise in interdisciplinary energy and environmental courses and degrees at the undergraduate and graduate levels. In the US for instance, the number and variety of such programs has increased significantly over the past decade, Simultaneously, national and international initiatives that integrate food, energy and water systems have been launched. This textbook provides a substantive introduction to the food-energy-water nexus suitable for use in higher level undergraduate and graduate level courses and for scholars moving into the field of nexus studies without a strong background in all three areas and the many aspects of nexus studies.




Nutrition and Human Health


Book Description

This book brings together innovative research that examines respectively climate change, agricultural production, environmental impacts, food security, nutrition and human health issues with regard to international policies as well as sustainable development goals. As sustainability continues to be a high concern in the scholarly community, food security has become a critical worldwide topic. Food supplies are challenged by factors such as toxicity, substandard food processes, difficulties in providing food to struggling populations and changes to the environment due to climate change egislation can protect public health, but law-makers must understand the current complications facing food security today. This book features a broad range of topics including ecotoxicology, smart food, and wastewater reuse impacts. The book aims to look at how we can protect and improve the health of vulnerable populations as well as innovative solutions to food insecurity. It is ideally designed for university students, from undergraduate to Ph.D. level, professors, researchers, professionals, environmentalists, physio-pathologists, medical doctors, epidemiologists, policies makers and sociologists.




Sustainable Food Waste-to-Energy Systems


Book Description

Sustainable Food Waste-to-Energy Systems assesses the utilization of food waste in sustainable energy conversion systems. It explores all sources of waste generated in the food supply chain (downstream from agriculture), with coverage of industrial, commercial, institutional and residential sources. It provides a detailed analysis of the conventional pathways for food waste disposal and utilization, including composting, incineration, landfilling and wastewater treatment. Next, users will find valuable sections on the chemical, biochemical and thermochemical waste-to-energy conversion processes applicable for food waste and an assessment of commercially available sustainable food waste-to-energy conversion technologies. Sustainability aspects, including consideration of environmental, economic and social impacts are also explored. The book concludes with an analysis of how deploying waste-to-energy systems is dependent on cross-cutting research methods, including geographical information systems and big data. It is a useful resource for professionals working in waste-to-energy technologies, as well as those in the food industry and food waste management sector planning and implementing these systems, but is also ideal for researchers, graduate students, energy policymakers and energy analysts interested in the most recent advances in the field. - Provides guidance on how specific food waste characteristics drive possible waste-to-energy conversion processes - Presents methodologies for selecting among different waste-to-energy options, based on waste volumes, distribution and properties, local energy demand (electrical/thermal/steam), opportunities for industrial symbiosis, regulations and incentives and social acceptance, etc. - Contains tools to assess potential environmental and economic performance of deployed systems - Links to publicly available resources on food waste data for energy conversion




Food, Energy, and Water Nexus


Book Description

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.
