Or that some types of waste can be made into energy? Investigate what we can do to reduce agricultural pollution. As part of the Searchlight BooksTM collection, this series sheds light on an important question—What Can We Do about Pollution? Informative text, compelling photos, and engaging captions will help you find the answer!

This comprehensive volume covers recent studies into agricultural problems caused by soil and water contamination. Considering the importance of agricultural crops to human health, the editors have focused on chapters detailing the negative impact of heavy metals, excessive chemical fertilizer use, nutrients, pesticides, herbicides, insecticides, agricultural wastes and toxic pollutants, among others, on agricultural soil and crops. In addition, the chapters offer solutions to these negative impacts through various scientific approaches, including using biotechnology, nanotechnology, nutrient management strategies, biofertilizers, as well as potent PGRs and elicitors. This book serves as a key source of information on scientific and engineered approaches and challenges for the bioremediation of agricultural contamination worldwide. This book should be helpful for research students, teachers, agriculturalists, agronomists, botanists, and plant growers, as well as in the fields of agriculture, agronomy, plant science, plant biology, and biotechnology, among others. It serves as an excellent reference on the current research and future directions of contaminants in agriculture from laboratory research to field application.

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.

Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

This document presents key messages and the state-of-the-art of soil pollution, its implications on food safety and human health. It aims to set the basis for further discussion during the forthcoming Global Symposium on Soil Pollution (GSOP18), to be held at FAO HQ from May 2nd to 4th 2018. The publication has been reviewed by the Intergovernmental Technical Panel on Soil (ITPS) and contributing authors. It addresses scientific evidences on soil pollution and highlights the need to assess the extent of soil pollution globally in order to achieve food safety and sustainable development. This is linked to FAO’s strategic objectives, especially SO1, SO2, SO4 and SO5 because of the crucial role of soils to ensure effective nutrient cycling to produce nutritious and safe food, reduce atmospheric CO2 and N2O concentrations and thus mitigate climate change, develop sustainable soil management practices that enhance agricultural resilience to extreme climate events by reducing soil degradation processes. This document will be a reference material for those interested in learning more about sources and effects of soil pollution.

Diffuse (non-point source) pollution is increasingly being recognised as a major source of water quality problems in both surface and ground water. Indeed, as pollution resulting from point sources is reduced by the efforts of regulators, diffuse sources frequently remain as the dominant source of pollution. The book is an introductory text covering the nature, causes and the significance of diffuse pollution of both urban and rural origin. Best management practices to tackle the problems are examined as are the ways in which the adoption of such practices may be brought about. Use is made of case studies from several countries to examine the strengths and weaknesses of various approaches. Diffuse Pollution covers both urban and rural sources. Urban sources include run-off from impermeable surfaces of roads, industrial areas and housing which may be contaminated by hydrocarbons, heavy metals, organic chemicals and other undesirable substances. Rural sources include water containing pollutants arising from agriculture and forestry such as plant nutrients, pesticides, microbes and soil itself. This concise book will prove useful to practitioners in the field of pollution control both in an urban and a rural environment, to regulators, to researchers new to the field, and to academics and students. An extensive reference section aids the reader in exploring the subject further.

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.
