Population Food Energy And The Environment

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.

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

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.

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.

Canadians are failing to balance reasonable food consumption with sufficient and sustainable production. The modern agricultural system is producing more and more food. Too much food. The cost is enormous: excess nutrients are contaminating the air and water; soil is being depleted; species loss is plunging us toward the sixth extinction; and farmers, racking up debt, are increasingly vulnerable to economic and climatic shifts. At the same time, people are consuming too much food. Two-thirds of health-care costs in Canada can be attributed to chronic diseases associated with unhealthy eating. And then there is the waste — householders, food processors, distributors, wholesalers, and retailers collectively waste 40 percent of the food produced. A radical rethink is required. We need to move from excess to enough.

Water, energy and food are key resources to sustain life, and are the fundamental to national, regional and global economies. These three resources are interlinked in multiple ways, and the term “nexus” captures the interconnections. The nexus has been discussed, debated, researched, and advocated widely but the focus is often on the pairings of “water-energy” or “water-food” or “energy-food”. To really benefit from the nexus approach in terms of resource use efficiency it is essential to understand, operationalize and practice the nexus of all three resources. As demand for these resources increases worldwide, using them sustainability is a critical concern for scientists and citizens, governments and policy makers. Volume highlights include: Contributions to the global debate on water-energy-food nexus Examples of the nexus approach in practice from different regions of the world Perspectives on the future of the nexus agenda Water-Energy-Food Nexus: Theories and Practices is a valuable resource for students, research scholars and professionals in academic institutions with strong interests in interdisciplinary research involving geography, earth science, environmental science, environmental management, sustainability science, international development, and ecological economics. The volume will also be useful for professionals, practitioners and consultants in /NGOs, government, and international agencies.
