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.
Название: Sampling and Isotope Analysis of Agricultural Pollutants in Water ISBN: 9201050186 ISBN-13(EAN): 9789201050182 Издательство: Mare Nostrum (Eurospan) Рейтинг: Цена: 17550.00 T Наличие на складе: Невозможна поставка. 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.

Описание: The Philippine economy has grown rapidly since 2010, but despite this growth, poverty and inequality remain high. Two-thirds of the poor live in rural areas, and the weak performance of the agriculture sector has contributed to the slow improvement in livelihoods. The challenge for agriculture will further increase, with climate change posing a growing threat to the sector. But agricultural transformation to spur sustained growth and reduce poverty is still possible under climate change with aggressive institutional reforms and implementation of the right mix of policies and programmes. The identification of the suitable policy and programme combination requires an accurate assessment of the key drivers of agricultural growth and food security; the impacts of climate change on agriculture and the overall economy; and the effectiveness of policies for adaptation and growth. This book addresses these big issues, focusing on enhancing the adaptation capacity of the Philippine agriculture sector. It is designed to provide a much-needed base of knowledge and menu of policy options to support decision- and policymaking on agriculture, climate change, and food security. The volume uses newly generated data, modelling outputs, and innovative analyses to provide a scientific basis for a variety of adaptation measures under different sets of climate change scenarios to guide decision-makers in strategic planning and policy formulation.
The case studies presented provide an integrated picture of how increasing climate variability and extremes are negatively affecting agriculture, resulting in destructive secondary impacts on livelihoods, income, food prices and coping capacities. These in turn lead to increased food insecurity.
According to the study, the challenge is to scale up and accelerate actions that strengthen the resilience of food systems and livelihoods to climate variability and extremes. Integrated, rather than dissociated, disaster risk reduction and management, as well as climate adaptation policies, programmes and practices are critical.
