DOWNLOAD EBOOK →The aim of this book is to document for the first time the dimensions and requirements of effective integrated groundwater management (IGM). Groundwater management is a formidable challenge, one that remains one of humanity’s foremost priorities. It has become a largely non-renewable resource that is overexploited in many parts of the world. In the 21st century, the issue moves from how to simply obtain the water we need to how we manage it sustainably for future generations, future economies, and future ecosystems. The focus then becomes one of understanding the drivers and current state of the groundwater resource, and restoring equilibrium to at-risk aquifers. Many interrelated dimensions, however, come to bear when trying to manage groundwater effectively. An integrated approach to groundwater necessarily involves many factors beyond the aquifer itself, such as surface water, water use, water quality, and ecohydrology. Moreover, the science by itself can only define the fundamental bounds of what is possible; effective IGM must also engage the wider community of stakeholders to develop and support policy and other socioeconomic tools needed to realize effective IGM. In order to demonstrate IGM, this book covers theory and principles, embracing: 1) an overview of the dimensions and requirements of groundwater management from an international perspective; 2) the scale of groundwater issues internationally and its links with other sectors, principally energy and climate change; 3) groundwater governance with regard to principles, instruments and institutions available for IGM; 4) biophysical constraints and the capacity and role of hydroecological and hydrogeological science including water quality concerns; and 5) necessary tools including models, data infrastructures, decision support systems and the management of uncertainty. Examples of effective, and failed, IGM are given. Throughout, the importance of the socioeconomic context that connects all effective IGM is emphasized. Taken as a whole, this work relates the many facets of effective IGM, from the catchment to global perspective.

DOWNLOAD EBOOK →This book is about accomplishing change in how land is managed in agricultural watersheds. Wide-ranging case studies repeatedly document that plans, policies, and regulations are not adequate substitutes for the empowerment of people. Ultimately change on the land is managed and accomplished by the people that live on land within each watershed.

DOWNLOAD EBOOK →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.

DOWNLOAD EBOOK →Agriculture is strongly affected by changes in soil hydrology as well as changes in land use and management practices and the complex interactions between them. This book develops an understanding of these interactions on a watershed scale, using soil hydrology models and addresses the consequences of land use and management changes on agriculture from a research perspective. Case studies illustrate the impact of land use and management on various soil hydrological parameters under different climates and ecosystems.

The two watersheds provided a unique opportunity to compare potential impacts of change in similar physical and climatological regions, yet under different political settings related to agricultural policies as well as water quality management and protection. The objectives of the research were to develop agricultural land use scenarios to apply to a hydrological model simultaneously with climate change simulations. This modelling framework allowed quantifying these combined impacts on streamflow, sediment loads, nitrate-nitrogen loads and concentrations, as well as total phosphorus loads and concentrations to the 2050 time horizon. The impacts of climate change were evaluated alone and then with land use change. Overall, the quality of surface water simulated in both watersheds will be deteriorated according to environmental standards set by the ministries by 2050 due to higher mean annual nutrient loads transported into the rivers. Climate change impacts were greater than land use change impacts; however land use change can have an important influence on water quality, depending on the magnitude of crop changes taking place. Field-level adaptation strategies in the Pike River were simulated to determine the extent of reducing the combined impacts of land use and climate change. The strategies were able to mitigate the combined impacts, and also to improve the quality of surface water compared to the in-stream nutrient concentrations in the reference simulation.In both watersheds, it was determined that the combined interaction between climate change and land use change in the hydrological model are non-linear. Examining the combined impacts are necessary to determine potential alterations in water quality in a basin since the direction and the magnitude are not predictable from the individual changes alone." --
