Book Description
"Viewing the subsistence farm as primarily a 'demographic enterprise' to create and support a family, this book offers an integrated view of the demography and ecology of preindustrial farming. Taking an interdisciplinary perspective, it examines how traditional farming practices interact with demographic processes such as childbearing, death, and family formation. It includes topics such as household nutrition, physiological work capacity, health and resistance to infectious diseases, as well as reproductive performance and mortality. The book argues that the farming household is the most informative scale at which to study the biodemography and physiological ecology of preindustrial, non-commercial agriculture. It offers a balanced appraisal of the farming system, considering its strengths and limitations, as well as the implications of viewing it as a 'demographic enterprise' rather than an economic one. A valuable resource for graduate students and researchers in biological and physical anthropology, cultural anthropology, natural resource management, agriculture and ecology"--

Book Description
For the past two decades, Integrated Water Resources Management (IWRM) has been the dominant paradigm in water resources. This book explores how ideas of IWRM are being translated and adapted in Mozambique, South Africa, Tanzania, Uganda and Zimbabwe. Grounded in social science theory and research, it highlights the importance of politics, history and culture in shaping water management practices and reform, and demonstrates how Africa has clearly been a laboratory for IWRM. While a new cadre of professionals made IWRM their mission, we show that poor women and men may not have always benefitted. In some cases IWRM has also offered a distraction from more critical issues such as water and land grabs, privatisation, the negative impacts of water permits, and a range of institutional ambiguities that prevent water allocations to small and poor water users. By critically examining the interpretations and challenges of IWRM, the book contributes to improving water policies and practices and making them more locally appropriate in Africa and beyond.

Book Description
Sustainability in agriculture and associated primary industries, which are both energy-intensive, is crucial for the development of any country. Increasing scarcity and resulting high fossil fuel prices combined with the need to significantly reduce greenhouse gas emissions, make the improvement of energy efficient farming and increased use of renewable energy essential. This book provides a technological and scientific endeavor to assist society and farming communities in different regions and scales to improve their productivity and sustainability. To fulfill future needs of a modern sustainable agriculture, this book addresses highly actual topics providing innovative, effective and more sustainable solutions for agriculture by using sustainable, environmentally friendly, renewable energy sources and modern energy efficient, cost-improved technologies. The book highlights new areas of research, and further R&D needs. It helps to improve food security for the rapidly growing world population and to reduce carbon dioxide emissions from fossil fuel use in agriculture, which presently contributes 22% of the global carbon dioxide emissions. This book provides a source of information, stimuli and incentives for what and how new and energy efficient technologies can be applied as effective tools and solutions in agricultural production to satisfy the continually increasing demand for food and fibre in an economically sustainable way, while contributing to global climate change mitigation. It will be useful and inspiring to decision makers working in different authorities, professionals, agricultural engineers, researchers, and students concerned with agriculture and related primay industries, sustainable energy development and climate change mitigation projects.

Book Description
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.

Book Description
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.

Book Description
This textbook explains the various aspects of sustainable agricultures to undergraduate and graduate students. The book first quantifies the components of the crop energy balance, i.e. the partitioning of net radiation, and their effect on the thermal environment of the canopy. The soil water balance and the quantification of its main component (evapotranspiration) are studied to determine the availability of water to rain fed crops and to calculate crop water requirements. Then it sets the limitations of crop production in relation to crop phenology, radiation interception and resource availability (e.g. nutrients). With that in mind the different agricultural techniques (sowing, tillage, irrigation, fertilization, harvest, application of pesticides, etc.) are analyzed with special emphasis in quantifying the inputs (sowing rates, fertilizer amounts, irrigation schedules, tillage plans) required for a given target yield under specific environmental conditions (soil & climate). For all techniques strategies are provided for improving the ratio productivity/resource use while ensuring sustainability. The book comes with online practical focusing on the key aspects of management in a crop rotation (collecting weather data, calculating productivity, sowing rates, irrigation programs, fertilizers rates etc).

Book Description
Ecological economics is a new transdisciplinary approach to understanding and managing the ecology and economics of our world for sustainability on local, regional, and global scales. The previous isolation of these two fields has led to economic and environmental policies that have been mutually destructive rather than reinforcing in the long term. This book brings together these two disciplines in chapters covering the basic worldview of ecological economics; accounting, modeling, and analysis of ecological economicl systems; and necessary institutional changes and case studies.
