The Future Role of Pesticides in US Agriculture


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.

Who Will Feed China?


Book Description

To feed its 1.2 billion people, China may soon have to import so much grain that this action could trigger unprecedented rises in world food prices. In Who Will Feed China: Wake-up Call for a Small Planet, Lester Brown shows that even as water becomes more scarce in a land where 80 percent of the grain crop is irrigated, as per-acre yield gains are erased by the loss of cropland to industrialization, and as food production stagnates, China still increases its population by the equivalent of a new Beijing each year. When Japan, a nation of just 125 million, began to import food, world grain markets rejoiced. But when China, a market ten times bigger, starts importing, there may not be enough grain in the world to meet that need - and food prices will rise steeply for everyone. Analysts foresaw that the recent four-year doubling of income for China's 1.2 billion consumers would increase food demand, especially for meat, eggs, and beer. But these analysts assumed that food production would rise to meet those demands. Brown shows that cropland losses are heavy in countries that are densely populated before industrialization, and that these countries quickly become net grain importers. We can see that process now in newspaper accounts from China as the government struggles with this problem.




Control of Water Pollution from Agriculture


Book Description

Agricultural operations can contribute to water quality deterioration through the release of several materials into water: sediments, pesticides, animal manures, fertilizers and other sources of inorganic and organic matter. This ''guidelines'' document on control and management of agricultural water pollution has the objectives of delineating the nature and consequences of agricultural impacts on water quality, and of providing a framework for practical measures to be undertaken by relevant professionals and decision-makers to control water pollution.




Pesticides


Book Description

Despite a history of several decades of pesticide regulation, continuous innovation, and considerable practical experience with using pesticides in agriculture, the environmental impact of pesticide use continues to be of serious concern.




Land Fragmentation and Rice Production


Book Description

Agricultural landholdings in China have an average size of only 0.53 hectares and are divided over six different plots on average. This very high degree of land fragmentation is likely to impose important constraints to current government policies aimed at supporting the incomes of rural households, raising domestic grain production, and promoting the overall production capacity of agricultural sector in order to meet the challenges posed by foreign competition. The purpose of this study is to examine the causes of this extremely high degree of land fragmentation and its consequences for food production in China. The analysis focuses in particular on rice smallholders in Jiangxi Province, a major rice production base of China.




Applied Soil Chemistry


Book Description

This book explores the state-of-the-art information regarding applied soil sciences. It covers the fundamentals, model concepts, principles, chemical reactions, functions, chemical recycling, chemical weathering, acid-base chemistry, carbon sequestration, and nutrient availability of soils. Also, it includes soil chemistry of heavy-metals, environment, clay, ion-exchange processes, analytical tools and applications. This book helps to understand the about soil characteristics targeting soil chemical reactions and interactions and its applications.




Sustainable Intensification


Book Description

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.
