Beyond the Biophysical provides a broad overview of agriculture and natural resource management (NRM) scholarship and practice that lies beyond the biophysical, emphasizing instead epistemological, cultural, and political foundations of NRM. The volume is oriented toward professionals with expertise in agriculture and natural resource management scholarship and practice, but who lack exposure to the conceptual and methodological underpinnings of critical theory, the anthropology of development, ecological anthropology, and other relevant scholarship. It therefore follows common standards of academic rigour, but minimizes the use of jargon, integrates detailed case studies with conceptual syntheses, and attempts to move from critique to concrete recommendations for scholarship and practice. The volume seeks to foster a more nuanced and responsible engagement with local communities and the natural world among NRM scholars and practitioners.

Soil enzymes are one of the vital key mediators involved in nutrient recycling and the decomposition of organic matter and thereby in maintaining soil quality and fertility. This Soil Biology volume covers the various facets of soil enzymes, such as their functions, biochemical and microbiological properties and the factors affecting their activities. Enzymes in the rhizosphere, in forest soils, and in volcanic ash-derived soils are described. Soil enzymes covered include phosphohydrolases, lignocellulose-degrading enzymes, phenol oxidases, fungal oxidoreductases, keratinases, pectinases, xylanases, lipases and pectinases. Several chapters treat the soil enzymatic activities in the bioremediation of soils contaminated with pesticides and pollutants such as oil, chlorinated compounds, synthetic dyes and aromatic hydrocarbons. The role of soil enzymes as bioindicators is a further important topic addressed.

Sir Richard Packer, former Permanent Secretary at MAFF, presided over Britain's most momentous political and public health crisis of the late twentieth century--BSE. In this frank account of events, Packer details the facts of the outbreak, how government responded to the crisis, and how the press contributed to widespread public panic. He reveals the awful truth about the lack of information about this new disease and how the decisions taken to protect public health were a combination of informed guesswork and sheer good fortune.

This volume discusses a broad range of vital issues encompassing the production and consumption of food in the current period of climate change. All of these add up to looming, momentous challenges to food security, especially for people in regions where malnutrition and famine have been the norm during numerous decades. Furthermore, threats to food security do not stop at the borders of more affluent countries - governance of food systems and changes in eating patterns will have worldwide consequences. The book is arranged in four broad sections. Part I, Combating Food Insecurity: A Global Responsibility opens with a chapter describing the urgent necessity for new paradigm and policy set to meet the food security challenges of climate change. Also in this section are chapters on meat and the dimensions of animal welfare, climate change and sustainability; on dietary options for mitigating climate change; and the linkage of forest and food production in the context of the REDD+ approach to valuation of forests. Part II, Managing Linkages Between Climate Change and Food Security offers a South Asian perspective on Gender, Climate Change and Household Food Security; a chapter on food crisis in sub-Saharan Africa; and separate chapters on critical issues of food supply and production in Nigeria, far-Western Nepal and the Sudano-Sahelian zone of Cameroon. Part III examines Food Security and patterns of production and consumption, with chapters focused on Morocco, Thailand, Bahrain, Kenya and elsewhere. The final section discusses successful, innovative practices, with chapters on Food Security in Knowledge-Based Economy; Biosaline Agriculture in the Gulf States; Rice production in a cotton zone of Benin; palm oil in the production of biofuel; and experiments in raised-bed wheat production. The editors argue that technical prescriptions are insufficient to manage the food security challenge. They propose and explain a holistic approach for adapting food systems to global environmental change, which demands the engagement of many disciplines - a new, sustainable food security paradigm.

Who controls what we eat? This book reveals how dominant corporations, from the supermarket to the seed industry, exert control over contemporary food systems. It analyzes the strategies these firms are using to reshape society in order to further increase their power, particularly in terms of their bearing upon the more vulnerable sections of society, such as recent immigrants, ethnic minorities and those of lower socioeconomic status. Yet this study also shows that these trends are not inevitable. Opposed by numerous efforts, from microbreweries to seed saving networks, it explores how opposition to this has encouraged even the most powerful firms to make small but positive changes. This revised edition has been updated to reflect recent developments in the food system, as well as the broad political economic forces that shape them. It also examines the rapidly changing technologies, such as Big Data and automation, which have the potential to reinforce, as well as to challenge, the power of the largest firms.

Agriculture was a major item on the agenda of the Uruguay Round of multilateral trade negotiations under the auspices of the General Agreement on Tariffs and Trade (GATT), launched in 1986. In this specially commissioned volume the national positions on agriculture taken up by the major players during the course of these negotiations are set out and analyzed, country by country, by a team of internationally renowned experts. The editors have selected and ordered the studies to provide a coherent assessment and synthesis of the main issues and areas of controversy raised by the negotiations. Examination of the reasons for the holding of different national perspectives on the issue of agricultural policy and trade reform helps to explain why reaching international agreement in this area of the GATT negotiations has been so elusive.

This specialist handbook is intended as a quick and easy reference guide to be used by individuals and organisations that are involved with the production of food, from both agriculture and horticulture. It is designed to be used as a reference book that answers basic questions about how food is produced from plants, and aims to demystify the subject of growing food as far as possible. The focus is firmly on the technical aspects of food crops; topics such as animal husbandry, agrochemicals and genetic engineering are only briefly mentioned. There is a strong international flavour to the book, with a view to making it user friendly throughout the English speaking community. In fact, the manual is designed to be also used by those who normally speak or read English as their second language, using simple English terminology and phrasing, with explanations and cross references of the terminology, acronyms and terms used.

In the past decade global change, mainly caused by climate change, and its effect on the society has been on the forefront of world news. Indeed, the issue has become a standard item on the agendas of political leaders, as it is feared that the economic costs caused by the predicted changes will be high, and mitigating measures consume scarce resources. Climate change is expected to impact heavily on human and animal health because of disturbance of ecological equilibriums and more favourable conditions for disease agents. Vector-borne diseases such as malaria, leishmaniasis and dengue will benefit particularly from the predicted changes by expansion of the geographic range of the vectors and accelerated development of the infectious parasites.

This book is the reflection of a workshop in which the potential impact of global change on malaria and other vector-borne diseases was discussed from different angles. The workshop brought together a series of leading scientists in the field of malaria and global change, to discuss the likelihood of changes in disease risk with respect to the scale of the predicted changes. Field research, laboratory studies and epidemiological modelling were presented and showed how combining theoretical modelling and field validations can be used to demonstrate the likely effects of global change on an infectious disease such as malaria. It was clear that environmental change, more than climate change, is the driving force behind the observed changes. The rapid spread of blue tongue, another highly infectious vector-borne disease, illustrates what might happen if the world looks on unguarded.

Globalization has become perhaps the most central--and one of the most contested--terms in the social sciences in the present day. If one wishes to understand the conditions in which different groups of people live today, it seems increasingly impossible to ignore the aspects of those conditions that are seen to be characterized, or influenced, by "global" forces, movements and phenomena. Regarding particular phenomena, no matter how apparently "local" or parochial in nature, as being located within "global" flows or systems or structures, seems today to be a very necessary component of any effective sort of social investigation. Many social scientific scholars in the last decade or so have engaged in a "global turn" in their thinking, investigating key areas and facets of human life--such as work, economy, cities, politics, and media--in terms of how these are being affected, influenced and changed by (what can be taken to be) "globalizing forces." Themes of inter-societal, trans-societal and cross-planetary connections, structures, processes and movements are increasingly central across the social sciences, including sociology, anthropology, geography, political science, economics, international relations, and many humanities disciplines too. Moreover, such themes--and the controversies and polemics often attached to them--have become common currency in many spheres outside the academy, with politicians, businesspeople, political activists and citizens of all varieties taking up ideas associated with "globalization," and deploying them both to make sense of, and also sometimes to try to change, the world around them. This book covers the issues of globalization as they relate to food. Contributors include Carole Counihan, Alan Warde, Pat Caplan, Alex McIntosh, Rick Wilk, Jeff Sobal, Marianne Lien and Krishnendu Ray.

The first premise of this book is that farmers need access to options for improving their situation. In agricultural terms, these options might be manage ment alternatives or different crops to grow, that can stabilize or increase household income, that reduce soil degradation and dependence on off-farm inputs, or that exploit local market opportunities. Farmers need a facilitating environment, in which affordable credit is available if needed, in which policies are conducive to judicious management of natural resources, and in which costs and prices of production are stable. Another key ingredient of this facilitating environment is information: an understanding of which options are viable, how these operate at the farm level, and what their impact may be on the things that farmers perceive as being important. The second premise is that systems analysis and simulation have an impor tant role to play in fostering this understanding of options, traditional field experimentation being time-consuming and costly. This book summarizes the activities of the International Benchmark Sites Network for Agrotechnology Transfer (IBSNAT) project, an international initiative funded by the United States Agency for International Development (USAID). IBSNAT was an attempt to demonstrate the effectiveness of understanding options through systems analysis and simulation for the ultimate benefit of farm households in the tropics and subtropics. The idea for the book was first suggested at one of the last IBSNAT group meetings held at the University of Hawaii in 1993."

Something is wrong with our agricultural and food systems. Despite great progress in increasing productivity in the last century, hundreds of millions of people remain hungry and malnourished. Can nothing be done or is it time for the expansion of another sort of agriculture, founded on more ecological principles, and in harmony with people, their societies and cultures?This book draws on many stories of successful transformation. A sustainable agriculture making the best of nature and people's knowledge and collective capacities has been showing increasingly good promise. Everyone is in favor of sustainability, yet few go seriously beyond the fine words. This book shows that there is no alternative to radical reform of national agricultural, rural and food policies, and institutions - the time has come for the next agricultural revolution.

Sustainable agriculture is a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. Sustainable agriculture is a discipline that addresses current issues such as climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control, and biodiversity depletion. Novel, environmentally-friendly solutions are proposed based on integrated knowledge from sciences as diverse as agronomy, soil science, molecular biology, chemistry, toxicology, ecology, economy, and social sciences. Indeed, sustainable agriculture decipher mechanisms of processes that occur from the molecular level to the farming system to the global level at time scales ranging from seconds to centuries. For that, scientists use the system approach that involves studying components and interactions of a whole system to address scientific, economic and social issues. In that respect, sustainable agriculture is not a classical, narrow science. Instead of solving problems using the classical painkiller approach that treats only negative impacts, sustainable agriculture treats problem sources. Because most actual society issues are now intertwined, global, and fast-developing, sustainable agriculture will bring solutions to build a safer world.
