Book Description
This book focuses on current food shortages and on the impact of pests in reducing world food supplies. At present, total worldwide food losses from pests are estimated to be about 45 percent. Preharvest losses alone, from insects, plant pathogens, and weeds, are estimated at about 30 percent. Additional postharvest losses from microorganisms, insects, and rodents range from about 10 to 20 percent. The contributors present data on the extent of these kinds of crop losses and analyze immediate and long-term pest management strategies. Emphasis is given to an evaluation of the effectiveness of integrated controls and the various new nonchemical pest controls used to reduce crop and livestock losses. The current worldwide environmental problems associated with both large-scale pesticide use and other pest control methods are also analyzed, including the impact that increased use of pesticides can be expected to have on the human environment. While the data included are technical, the presentation and analysis will be of interest to both the scientific community and the general public.

Book Description
Ecofriendly Pest Management for Food Security explores the broad range of opportunity and challenges afforded by Integrated Pest Management systems. The book focuses on the insect resistance that has developed as a result of pest control chemicals, and how new methods of environmentally complementary pest control can be used to suppress harmful organisms while protecting the soil, plants, and air around them. As the world's population continues its rapid increase, this book addresses the production of cereals, vegetables, fruits, and other foods and their subsequent demand increase. Traditional means of food crop production face proven limitations and increasing research is turning to alternative means of crop growth and protection. - Addresses environmentally focused pest control with specific attention to its role in food security and sustainability. - Includes a range of pest management methods, from natural enemies to biomolecules. - Written by experts with extensive real-world experience.

Book Description
Given the central role of the food and agriculture system in driving so many of the connected ecological, social and economic threats and challenges we currently face, Rethinking Food and Agriculture reviews, reassesses and reimagines the current food and agriculture system and the narrow paradigm in which it operates. Rethinking Food and Agriculture explores and uncovers some of the key historical, ethical, economic, social, cultural, political, and structural drivers and root causes of unsustainability, degradation of the agricultural environment, destruction of nature, short-comings in science and knowledge systems, inequality, hunger and food insecurity, and disharmony. It reviews efforts towards 'sustainable development', and reassesses whether these efforts have been implemented with adequate responsibility, acceptable societal and environmental costs and optimal engagement to secure sustainability, equity and justice. The book highlights the many ways that farmers and their communities, civil society groups, social movements, development experts, scientists and others have been raising awareness of these issues, implementing solutions and forging 'new ways forward', for example towards paradigms of agriculture, natural resource management and human nutrition which are more sustainable and just. Rethinking Food and Agriculture proposes ways to move beyond the current limited view of agro-ecological sustainability towards overall sustainability of the food and agriculture system based on the principle of 'inclusive responsibility'. Inclusive responsibility encourages ecosystem sustainability based on agro-ecological and planetary limits to sustainable resource use for production and livelihoods. Inclusive responsibility also places importance on quality of life, pluralism, equity and justice for all and emphasises the health, well-being, sovereignty, dignity and rights of producers, consumers and other stakeholders, as well as of nonhuman animals and the natural world. - Explores some of the key drivers and root causes of unsustainability , degradation of the agricultural environment and destruction of nature - Highlights the many ways that different stakeholders have been forging 'new ways forward' towards alternative paradigms of agriculture, human nutrition and political economy, which are more sustainable and just - Proposes ways to move beyong the current unsustainable exploitation of natural resources towards agroecological sustainability and overall sustainability of the food and agriculture system based on 'inclusive responsibility'

Book Description
Although chemical pesticides safeguard crops and improve farm productivity, they are increasingly feared for their potentially dangerous residues and their effects on ecosystems. The Future Role of Pesticides explores the role of chemical pesticides in the decade ahead and identifies the most promising opportunities for increasing the benefits and reducing the risks of pesticide use. The committee recommends R&D, program, and policy initiatives for federal agriculture authorities and other stakeholders in the public and private sectors. This book presents clear overviews of key factors in chemical pesticide use, including: Advances in genetic engineering not only of pest-resistant crops but also of pests themselves. Problems in pesticide useâ€"concerns about the health of agricultural workers, the ability of pests to develop resistance, issues of public perception, and more. Impending shifts in agricultureâ€"globalization of the economy, biological "invasions" of organisms, rising sensitivity toward cross-border environmental issues, and other trends. With a model and working examples, this book offers guidance on how to assess various pest control strategies available to today's agriculturist.

Book Description
New evidence this year corroborates the rise in world hunger observed in this report last year, sending a warning that more action is needed if we aspire to end world hunger and malnutrition in all its forms by 2030. Updated estimates show the number of people who suffer from hunger has been growing over the past three years, returning to prevailing levels from almost a decade ago. Although progress continues to be made in reducing child stunting, over 22 percent of children under five years of age are still affected. Other forms of malnutrition are also growing: adult obesity continues to increase in countries irrespective of their income levels, and many countries are coping with multiple forms of malnutrition at the same time – overweight and obesity, as well as anaemia in women, and child stunting and wasting.

As man's ability to disrupt the climate becomes increasingly apparent,evidence is mounting that human-activity-induced climate changes may well rival anything nature can produce. If the consensus of the international climatological community is correct, and if worldwide use of fossil fuel continues to increase atmospheric carbon dioxide, mankind is

Book Description
The Global 2000 Report to the President of the U.S.: Entering the 21st Century, Volume I: The Summary Report focuses on the Global 2000 Study, particularly noting the issues on the environment, population, and natural resources. The book first offers information on the findings and conclusions of the study and environment projections. Topics include water, energy, and forestry projections and the environment; climate changes and the environment; and gross national product (GNP) projections and the environment. The manuscript then examines the "Government's Global Model," including the analysis of the foundation, interpretation of projections, and strengthening the foundation. The text examines the elements of the ""Government's Global Model."" These include population, GNP, climate, technology, food, fisheries, forestry, water, energy, and fuel minerals. The book also surveys some of the studies and task forces whose findings might be helpful to those trying to provide methods and instructions in support of decision-making for international efforts in population, resources, and the environment. The manuscript will surely serve readers interested in the study of international efforts on population, resources, and the environment.
