Описание: In emerging East Asia, agricultural output has expanded dramatically over recent decades, primarily as a result of successful efforts to stimulate yield growth. This achievement has increased the availability of food and raw materials in the region, drastically diminished hunger, and more generally provided solid ground for economic development. The intensification of agriculture that has made this possible, however, has also led to serious pollution problems that have adversely affected human and ecosystem health, as well as the productivity of agriculture itself. In the region that currently owes the largest proportion of deaths to the environment, agriculture is often portrayed as a victim of industrial and urban pollution, and this is indeed the case. Yet agriculture is taking a growing toll on economic resources and sometimes becoming a victim of its own success. In parts of China, Vietnam, and the Philippines—the countries studied in The Challenge of Agricultural Pollution—this pattern of highly productive yet highly polluting agriculture has been unfolding with consequences that remain poorly understood. With large numbers of pollutants and sources, agricultural pollution is often undetected and unmeasured. When assessments do occur, they tend to take place within technical silos, and so the different ecological and socioeconomic risks are seldom considered as a whole, while some escape study entirely. However, when agricultural pollution is considered in its entirety, both the significance of its impacts and the relative neglect of them become clear. Meanwhile, growing recognition that a “pollute now, treat later” approach is unsustainable—from both a human health and an agroindustry perspective—has led public and private sector actors to seek solutions to this problem. Yet public intervention has tended to be more reactive than preventive and often inadequate in scale. In some instances, the implementation of sound pollution control programs has also been confronted with incentive structures that do not rank environmental outcomes prominently. Significant potential does exist, however, to reduce the footprint of farms through existing technical solutions, and with adequate and well-crafted government support, its realization is well within reach.

Описание: Agricultural pollution (with nitrates and pesticides) is one of the biggest threats to drinking water resources. Three national case studies (Germany, The Netherlands, and the United Kingdom) analyse these efforts within the context of problematical national agricultural policy and the need to implement EU directives on water quality.

Описание: Agri-environment schemes (AES) is frequently adopted for tricky environmental issues. One key concern for AES design is to optimize the cost-effectiveness. For issues of cost-effective prevention of agricultural soil erosion and non-point source water pollution, although models that assess both environmental effects and economic costs of land use measures have been developed, they typically adopt a planning perspective instead of designing AES with the role of farmers being considered. This book presents a spatially explicit novel integrated modelling approach that addresses the shortcoming by combining several components. The relevance of the modelling approach is demonstrated in this book by applying it to the Baishahe watershed in Shanxi province in China. The results show that the modelling approach is robust to design cost-effective AES, i.e. under given budget the maximum environmental effect in the study region could be attained with a set of designed payments for measures in AES. The developed modelling approach is generic and powerful for application in all kinds of agricultural watersheds with various sizes.

Описание: Stable isotope techniques can help identify the sources of water pollution associated with agricultural activities. Knowing the origin of nutrients or contaminants is essential to improve agricultural practices. To ensure the quality of stable isotope analysis, appropriate sampling and sample preparation are crucial. This publication presents methods for surface water sampling and sample processing through micro-diffusion and bacterial denitrification combined with laser spectroscopy. Information on such methods is often described in a very summarized and non-comprehensive way without proper illustration of every step. This publication aims to bridge this gap for scientists, technicians and students. It presents a selection of standard operating procedures providing guidance in water sampling and sample preparation that are mandatory when conducting reliable isotope analysis on water.

Описание: Nutrients are elements essential to plant and animal growth. In agricultural production, the focus generally rests on the three primary macronutrients -- nitrogen (N), phosphorus (P), and potassium (K) -- because of their relative abundance in plants. As crops grow and are harvested, they gradually remove the existing nutrients from the soil and over time will require additional nutrients to maintain or increase crop yield. When nutrients are added in excess of the plants ability to utilize them, there is an increased risk that the nutrients will enter the surrounding environment (water or air) and create environmental problems. The nutrients of primary environmental concern in agriculture are nitrogen and phosphorus. This book discusses the types and sources of nutrient pollution from agricultural production; possible environmental effects of nutrient pollution; examples of current control measures; the federal response to excess nutrients, including regulatory and incentive-based programs; and future considerations for nutrient management policy at the federal level.
