"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.

The agri-food chain consumes about one third of the world’s energy production with about 12% of it for crop production and nearly 80% for processing, distribution, retail, preparation and cooking. The agri-food chain also accounts for 80-90% of total global freshwater use where 70% alone is for irrigation. Additionally, on a global scale, freshwater production consumes nearly 15% of the entire energy production. It can therefore be argued that making agriculture and the agri-food supply chain independent from fossil fuel use has a huge potential to contribute to global food security and climate protection not only for the next decades but also for the coming century. Provision of secure, accessible and environmentally sustainable supplies of water, energy and food must thus be a priority. One of the major objectives of the world’s scientists, farmers, decisions makers and industrialists is to overcome the present dependence on fossil fuels in the agro-food sector. This dependency increases the volatility of food prices and affects economic access to sustenance. This book provides a critical review of recent developments in solar, wind and geothermal energy applications in agriculture and the agro-food sector such as processing, distribution, retail, preparation and cooking.

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.

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.

Geothermal energy refers to the heat contained within the Earth that generates geological phenomena on a planetary scale. Today, this term is often associated with man's efforts to tap into this vast energy source. Geothermal Energy: utilization and technology is a detailed reference text, describing the various methods and technologies used to exploit the earth's heat. Beginning with an overview of geothermal energy and the state of the art, leading international experts in the field cover the main applications of geothermal energy, including: electricity generation space and district heating space cooling greenhouse heating aquaculture industrial applications The final third of the book focuses upon environmental impact and economic, financial and legal considerations, providing a comprehensive review of these topics. Each chapter is written by a different author, but to a set style, beginning with aims and objectives and ending with references, self-assessment questions and answers. Case studies are included throughout. Whilst written primarily for professionals and students interested in learning more about geothermal energy, the book also offers those new to the field and the general geothermal community an opportunity to understand and review the potential of this exciting alternative energy source.

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.
