This is a print on demand edition of a hard to find publication. Energy is an important input in growing, processing, packaging, distributing, storing, preparing, serving, and disposing of food. In the U.S., use of energy along the food chain for food purchases by or for U.S. households increased between 1997 and 2002 at more than six times the rate of increase in total domestic energy use. This increase in food-related energy flows is over 80% of energy flow increases nationwide over the period. The use of more energy-intensive technologies throughout the U.S. food system accounted for half of this increase, with the remainder attributed to population growth and higher real per capita food expenditures. Food-related energy use as a share of the national energy budget grew from 14.4% in 2002 to 15.7% in 2007. Illus.
In 2021, the United Nations Secretary-General will convene the Food Systems Summit to advance dialogue and action towards transforming the way the world produces, consumes and thinks about food guided by the overarching vision of a fairer, more sustainable world. The Secretary-General will also convene the High-Level Dialogue on Energy (HLDE) to promote the implementation of the energy-related goals and targets of the 2030 Agenda for Sustainable Development. Given the inextricable linkages between the energy and agriculture sectors, integrating the nexus perspective within the FSS and the HLDE is crucial to formulate a joint vision of actions to advance the 2030 Agenda for Sustainable Development and the Paris Agreement. In this context, IRENA and FAO have decided to jointly develop a report on the role of renewable energy used in food chain to advance energy and food security as well as climate action towards the achievement of Sustainable Development Goals and the Paris Agreement. While energy has a key enabling role in food system transformation and innovation in agriculture, its current use is unsustainable because of the high dependence on fossil fuels and frequent access to energy in developing countries. The challenge is to disconnect fossil fuel use from food system transformation without hampering food security. The use of renewable energy in food systems offers vast opportunities to address this challenge and help food systems meet their energy needs while advancing rural development while contributing to rural development and climate action.
How we produce and consume food has a bigger impact on Americans' well-being than any other human activity. The food industry is the largest sector of our economy; food touches everything from our health to the environment, climate change, economic inequality, and the federal budget. From the earliest developments of agriculture, a major goal has been to attain sufficient foods that provide the energy and the nutrients needed for a healthy, active life. Over time, food production, processing, marketing, and consumption have evolved and become highly complex. The challenges of improving the food system in the 21st century will require systemic approaches that take full account of social, economic, ecological, and evolutionary factors. Policy or business interventions involving a segment of the food system often have consequences beyond the original issue the intervention was meant to address. A Framework for Assessing Effects of the Food System develops an analytical framework for assessing effects associated with the ways in which food is grown, processed, distributed, marketed, retailed, and consumed in the United States. The framework will allow users to recognize effects across the full food system, consider all domains and dimensions of effects, account for systems dynamics and complexities, and choose appropriate methods for analysis. This report provides example applications of the framework based on complex questions that are currently under debate: consumption of a healthy and safe diet, food security, animal welfare, and preserving the environment and its resources. A Framework for Assessing Effects of the Food System describes the U.S. food system and provides a brief history of its evolution into the current system. This report identifies some of the real and potential implications of the current system in terms of its health, environmental, and socioeconomic effects along with a sense for the complexities of the system, potential metrics, and some of the data needs that are required to assess the effects. The overview of the food system and the framework described in this report will be an essential resource for decision makers, researchers, and others to examine the possible impacts of alternative policies or agricultural or food processing practices.
Food and Energy Resources provides an understanding of the influence of energy, land, and water resources on food production. Future supplies of energy resources will have a major impact on the ability of humans to provide themselves with food. A better understanding of these issues will help society make sound choices and enable government leaders to develop and organize the necessary programs for the effective use of energy and food resources. The book begins with a discussion of the energy flow in the food system. This is followed by chapters that examine alternatives for the use of the external solar energy; the role of energy in world agriculture and food supply; the energy, land, and labor inputs in several major crop systems in northeastern China; and energy and food relationships in developing countries. Subsequent chapters deal with issues such as the use of renewable energy sources and the extent to which agricultural resources are used to produce food or fuel. This book will provide engineers, economists, agriculturists, geographers, ecologists, nutritionists, sociologists, and natural resource specialists a perspective that will help solve the problem of providing food for people while protecting natural resources.
Sustainable Food Systems from Agriculture to Industry: Improving Production and Processing addresses the principle that food supply needs of the present must be met without compromising the ability of future generations to meet their needs. Responding to sustainability goals requires maximum utilization of all raw materials produced and integration of activities throughout all production-to-consumption stages. This book covers production stage activities to reduce postharvest losses and increase use of by-products streams (waste), food manufacturing and beyond, presenting insights to ensure energy, water and other resources are used efficiently and environmental impacts are minimized. The book presents the latest research and advancements in efficient, cost-effective, and environmentally friendly food production and ways they can be implemented within the food industry. Filling the knowledge gap between understanding and applying these advancements, this team of expert authors from around the globe offer both academic and industry perspectives and a real-world view of the challenges and potential solutions that exist for feeding the world in the future. The book will guide industry professionals and researchers in ways to improve the efficiency and sustainability of food systems. - Addresses why food waste recovery improves sustainability of food systems, how these issues can be adapted by the food industry, and the role of policy making in ensuring sustainable food production - Describes in detail the latest understanding of food processing, food production and waste reduction issues - Includes emerging topics, such as sustainable organic food production and computer aided process engineering - Analyzes the potential and sustainability of already commercialized processes and products
Farming for Our Future examines the policies and legal reforms necessary to accelerate the adoption of practices that can make agriculture in the United States climate-neutral or better. These proven practices will also make our food system more resilient to the impacts of climate change. Agriculture's contribution to climate change is substantial--much more so than official figures suggest--and we will not be able to achieve our overall mitigation goals unless agricultural emissions sharply decline. Fortunately, farms and ranches can be a major part of the climate solution, while protecting biodiversity, strengthening rural communities, and improving the lives of the workers who cultivate our crops and rear our animals. The importance of agricultural climate solutions can not be underestimated; it is a critical element both in ensuring our food security and limiting climate change. This book provides essential solutions to address the greatest crises of our time.
This book features a comprehensive foresight assessment, exploring the pressures — threats as well as opportunities — on the global agriculture & food systems between now and 2050. The overarching aim is to help readers understand the context, by analyzing global trends and anticipating change for better planning and constructing pathways from the present to the future by focusing on the right questions and problems. The book contextualizes the role of international agricultural research in addressing the complex challenges posed by UN 2030 Agenda and beyond, and identifies the decisions that scientific leaders, donors and policy makers need to take today, and in the years ahead, to ensure that a global population rising to nine billion or more combined with rising incomes and changing diets can be fed sustainably and equitably, in the face of the growing climate threats.
"Agriculture and agro-industry are important sectors in the economies of most developing countries, where they provide the main source of livelihoods for the majority of the poor. The lack of a sustainable supply of affordable energy is a major constraint to the development of these sectors in developing countries. Traditionally, geothermal energy has been utilized mainly to generate electricity; however, it can be harnessed for other important uses in agriculture and agro-industry. Developing countries endowed with this renewable energy source have ample potential to use it in advancing their agriculture and agro-industry sectors. This book reviews the use of geothermal energy in agriculture and agro-industry around the world. With a simple format and copious illustrations and models, the book is accessible to a wide range of interested readers, including those with no technical background. It shows that geothermal resources have the potential to provide long-term, secure energy for the agriculture and food industry in both developed and developing countries. Constraints and challenges that should be addressed before this potential can be fully achieved are also discussed."--Publisher's description.
