Fertilizers have been used extensively around the globe since the Green Revolution, due to the high subsidies. However, extensive fertilizer use exacerbates soil degradation and causes yield stagnation, and as a result threatens food security and soil sustainability, especially in developing countries. This means that sustainable soil and environmental management are vital to provide food and nutritional security for present and future generations. This has led to the International Union of Soil Science (IUSS) declaring 2015-2024 the International Decade of Soils. This book focuses on the impact of sustainable management of soil and environment on improving the functioning of soil-ecosystems and agronomic productivity, and also discusses food security, nutrient cycling, recent advances in INM technologies, eco-friendly cultivation, agricultural practices to reduce greenhouse gas (GHG) emissions, as well as conservation agriculture and its effects, and strategies for soil sustainability. Offering a comprehensive overview of management in the context of the sustainability of soil and the agroecosystems that it supports, it demonstrates the options available and provides insights into restoring soil health and matching soil nutrient supply with crop demand to ensure nutritional security in an eco-friendly environment.

Emission inventory is basic for the understanding of environmental behaviors and potential effects of compounds, however, current inventories are often associated with relatively high uncertainties. One important reason is the lack of emission factors (EFs), especially for the residential solid fuel combustion in developing countries. In the present study, emission factors of a group of pollutants including particulate matter, organic carbon, elemental carbon (sometimes known as black carbon) and polycyclic aromatic hydrocarbons were measured for a variety of residential solid fuels including coal, crop straw, wood, and biomass pellets in rural China. The study provided a large number of emission factors that can be further used in emission estimation. Composition profiles and isomer ratios were investigated and compared so as to be used in source apportionment. In addition, the present study identified and quantified the influence of factors like fuel moisture, volatile matter on emission performance. The publication of the study will be of interest and helpful to the readers in the field of air pollution, human health, fuel saving and energy consumption etc. Guofeng Shen works at the Institute of Atmospheric Sciences, Jiangsu Academy of Environmental Sciences, China.

Due to their unparalleled effectiveness and efficiency, polyfluorinated chemicals (PFC") "have become essential in numerous technical applications. However, many PFCs brought to market show limited biodegradability, and their environmental persistence combined with toxic and bioaccumulative potential have become a matter of concern in some instances. This volume highlights the synthesis of PFCs, focusing on substances with improved application and environmental properties, which are a challenge for synthetic chemists. Further, modern mass spectrometric techniques for the detection and identification of biotransformation products of PFCs are described. The sorption and leaching behavior of PFC in soil is also addressed in order to predict their fate in the environment. Several contributions discuss the monitoring of PFCs in European surface, ground and drinking waters, treatment options for PFC removal from drinking water, occurrence in food, and the human biomonitoring of PFCs.
This book addresses the synthesis of photosensitizers, the main emphasis being on the new methods of synthesis such as microwave, sonochemistry and the use of ionic liquids. It also addresses the photochemistry and photophysics of the photosensitizers alone and in combination with nanoparticles, the use of the photosensitizers in environmental control, safety and medicine. It discusses the common structures of the photosensitizers which are beneficial to these applications. "
Many large mathematical models, not only models arising and used in
environmental studies, are described by systems of partial
differential equations. The discretization of the spatial
derivatives in such models leads to the solution of very large
systems of ordinary differential equations. These systems contain
many millions of equations and have to be handled over large time
intervals by applying many time-steps (up to several hundred
thousand time-steps). Furthermore, many scenarios are as a rule to
be run. This explains the fact that the computational tasks in this
situation are enormous. Therefore, it is necessary to select fast
numerical methods; to develop parallel codes and, what is most
important when the problems solved are very large to organize the
computational process in a proper way.

The 5th volume of Green Chemical Processing considers sustainable chemistry in the context of governmental and corporate interests, explaining how "red tape" can help or hinder the "greening" of industry processes. The American Chemical Society's 12 Principles of Green Chemistry are woven throughout this text as well as the series to which this book belongs.
Freezing and thawing of soils is a common phenomenon in the winter-cold zone. The thesis titled "Material Cycling of Wetland Soils Driven by Freeze-Thaw Effects" systematically explores the freeze-thaw effects on the accumulation and release processes of carbon and nitrogen in wetland soils, which is a good step toward the investigation of biogeochemical processes in wetlands in seasonal freeze-thaw areas. It is also developing strategies aimed at global warming effects on the accumulation and release of carbon and nitrogen in wetlands.

sector. This ensured eventual transfer of the technology demonstrated at the wo- shops and Technical Meetings to marketable devices. BIOSET provided assistance for researchers from European laboratories to meet to exchange ideas, use equ- ment, and establish a basis for new joint projects. The secretariat of the Concerted Action BIOSET supported the Technical Meetings. There were three Technical Meetings held, two in Berlin in 1997 and 1998, and the third in Barcelona, in April 2000. The goal of these technical meetings was to join different research and industrial teams to evaluate the performance of their biosensor technology in field conditions with common and standardized surface and waste waters. As a result of these field experiments, the additional information that biosensors can offer to environmental monitoring was also evaluated. Thus, these three Technical Meetings were useful accompanying measures and practical additions to the currently organized yearly workshops. The concerted action BIOSET was f- lowed by the SENSPOL network. The 1st SENSPOL Workshop was held on the 9-11 May 2001 on Sensing Technologies for Contaminated Sites and Groundwater at the University of Alcala. There was one special Workshop on "Genotoxicity Biosensing (TECHNOTOX)" supported by the European Commission DG XII D-1 and BIOSET in the year 2000. The TECHNOTOX meeting at the Flemish Institute for Technological Research (VITO) in Mol was organized by Phillippe Corbisier (VITO), Peter-D. Hansen (TU Berlin) and Damia Barcelo (CSIC Barcelona).
This volume describes what is arguably the first and only valuation study to meet in full the reference study standards set by NOAA's Blue Ribbon Panel on Contingent Valuation. This book documents a contingent valuation study for a generic environmental good: preventing the likely injuries from oil spills on the coast of Central California. It provides a wealth of materials which will reduce the long lead time which characterizes most economic damage assessments. This is achieved by so richly documenting the design, administration, and analysis of such studies as to be effectively a 'how-to' guide for undertaking state-of-the-art contingent valuation studies. The book is supported by a CD-ROM containing a wealth of additional material, including data, questionnaires, and transcripts. Together, they constitute a unique and vital contribution to the literature concerning the valuation of non-market preferences.
Nitrous oxide gas is a long-lived relatively active greenhouse gas (GHG) with an atmospheric lifetime of approximately 120 years, and heat trapping effects about 310 times more powerful than carbon dioxide per molecule basis. It contributes about 6% of observed global warming. Nitrous oxide is not only a potent GHG, but it also plays a significant role in the depletion of stratospheric ozone. This book describes the anthropogenic sources of N2O with major emphasis on agricultural activities. It summarizes an overview of global cycling of N and the role of nitrous oxide on global warming and ozone depletion, and then focus on major source, soil borne nitrous oxide emissions. The spatial-temporal variation of soil nitrous oxide fluxes and underlying biogeochemical processes are described, as well as approaches to quantify fluxes of N2O from soils. Mitigation strategies to reduce the emissions, especially from agricultural soils, and fertilizer nitrogen sources are described in detail in the latter part of the book.

This second volume of Frontiers articles contains a broad array of
fascinating topics. The first four
Throughout the world's arid regions, and particularly in northern
and eastern Africa, formerly nomadic pastoralists are undergoing a
transition to settled life. Pastoral sedentarization represents a
response to multiple factors, including loss of livestock due to
drought and famine, increased competition for range land due to
growing populations, land privatization or appropriation for
commercial farms, ranches, and tourist game parks, and to fear of
increasing violence, ethnic conflict, and civil war. Although
pastoral settlement is often encouraged by international
development agencies and national governments as solutions to food
insecurity, poor health care and problems of governance, the
social, economic and health concomitants of sedentism are not
inevitably beneficial. Biosocial studies presented in this volume,
for example, point to greater nutritional and health benefits among
nomadic livestock keepers, but increased opportunities in
education, employment, and food security in towns.
Since the first symposium in 1984 the International Symposia on Spatial Data Handling (SDH) has become a major resource for recent advances in GIS research. The International Symposium on Spatial Data Handling is regarded as a premier international research forum for GIS. All papers are fully reviewed by an international program committee composed of experts in the field.

This book covers a range of topics including the exploration of modern resources, such as ore deposits, coal mines, shale gas and geothermal power, and the monitoring of geological disasters, including the rock-soil body, ground deformation, mines, specific rock-soil engineering disasters, desertification of land and environmental abnormalities. This book not only offers a valuable resource for geophysical researchers; it also demonstrates how geophysics theories and methods can be practically implemented to protect our environment and promote the development of human society.
This book presents the proceedings and the outcomes of the NATO Advanced Research Workshop (ARW) on Integrated Technologies for Environmental Monitoring and Information Production, which was held in Marmaris, Turkey, between September 10- 14, 200 I. With the contribution of 45 experts from 20 different countries, the ARW has provided the opportunity to resolve the basic conflicts that tend to arise between different disciplines associated with environmental data management and to promote understanding between experts on an international and multidisciplinary basis. The prevailing universal problem in environmental data management (EDM) systems is the significant incoherence between data collection procedures and the retrieval of information required by the users. This indicates the presence of problems still encountered in the realization of; (1) delineation of objectives, constraints, institutional aspects of EDM; (2) design of data collection networks; (3) statistical sampling; (4) physical sampling and presentation of data; (5) data processing and environmental databases; (6) reliability of data; (7) data analysis and transfer of data into information; and (8) data accessibility and data exchange at local, regional and global scales. Further problems stem from the lack of coherence between different disciplines involved in EDM, lack of coordination between responsible agencies on a country basis, and lack of coordination on an international level regarding the basic problems and relevant solutions that should be sought.
For the past 3.8 billion years, the geochemistry of the Earth's surface - its atmosphere, waters and exposed crust - has been determined by the presence of biota. Photosynthetic organisms exposed the Earth's surface to oxygen, denitrifying bacteria have maintained the nitrogen concentration in Earth's atmosphere, and land plants have determined the rate of chemical weathering. Life determines the global biogeochemical cycles of the elements of biochemistry, especially C, N, P and S. Volume 8 traces the origin and impact of life on the geochemistry of the Earth's surface, with special emphasis on the current human impact on global biogeochemical cycles.
Volume 9 focuses on natural and anthropogenic environmental contaminants and their implications for human health and the environment. Environmental impacts on soils, groundwater, freshwater, the oceans and atmosphere are examined in the context of both inorganic geochemistry (metals, metalloids, radioactive compounds, mineral dusts, dissolved salts, acidification) and organic geochemistry (halogenated and non-halogenated hydrocarbons, volatile organic compounds, fuel oxygenates, pesticides, nutrients). Issues of risk, toxicity and exposure assessment; contaminant fate and transport; remediation and disposal; and source identification are examined in this context.
