Book Description
Environmental management is a wide, expanding, and rapidly evolving field, affecting everyone from individual citizens to businesses; governments to international agencies. Indisputably, it plays a crucial role in the quest for sustainable development. This comprehensively updated second edition explores the nature and role of environmental management, covering key principles, practices, tools, strategies and policies, offers a thorough yet understandable introduction, and points to further in-depth coverage. Among the key themes covered are: sustainable development proactive approaches the precautionary principle the ‘polluter pays’ principle the need for humans to be less vulnerable and more adaptable. Reflecting the expansion and evolution of the field, this revised edition focuses strongly on sustainable development. There has been extensive restructuring to ensure the book is accessible to those unfamiliar with environmental management and it now includes greater coverage of topics including key resources under stress, environmental management tools, climate change and urban environmental management. With rapid expansion and development of the subject it is easy for those embarking on a course of study to become disorientated, but with its well-structured coverage, effective illustrations, and foundation for further, more-focused interest, this book is easily accessible to all.

Book Description
This book deals with the ecology of rivers and streams in the Oriental Region, and describes the composition of their unique fauna - especially the diverse array of animals which live on and among the bottom sediments. Dichotomous keys are provided as an aid to the identification of these animals, and the book is illustrated by over 100 pages of line drawings and maps. Special emphasis is given to the impact of human activities on streams and rivers, and the book concludes with a discussion of conservation and management options for these endangered habitats.

Book Description
Human population is growing rapidly, disproportionate to food supply, which necessitate production of more volume of food in the near future. The reliance on insecticides for quick and dramatic results was not totally free from adverse effects. This book intends to fill the gap by providing a critical analysis of different management strategies that have a bearing on agriculture, sustainability, and environmental protection. This book emphasizes the management strategies with evaluation of each strategy in the bigger picture of ecologically driven pest management. This book includes 24 chapters, which cover ecological and biorational basis of pest management, integrated pest and disease management, crop breeding for resistance, use of entomopathogenic nematodes and other agents, remote sensing, biosecurity issues, risk to biodiversity by exotic species, new and emerging pests of horticultural crops, saffron and stored grains, the role of extension technologies in dissemination of IPM and, future challenges and strategies. The book is aimed to serve as reference book for teachers, researchers, extension officers, and policy makers associated with IPM. This book can also be used as supplementary reading material in undergraduate and postgraduate courses. This book provides a multidisciplinary IPM perspective to entomologists, plant pathologists, extension educationists, anthropologist and economists.

Book Description
These proceedings of a NATO Advanced Research Workshop on "Environmental Reconstruction in Headwater Areas" provide a landmark in the evolution of a distinctive movement, perhaps an emerging new philosophy, within the practice of headwater management. The Headwater Control movement traces its history back to the First International Conference on Headwater Control, Prague, 1989. Throughout this brief history, Headwater Control has remained a typical environment movement 'ad hocracy'. At its meetings, for every convert to the multidisciplinary, integrative, practical, interventionist, and above-all 'green' ideals of the group, there have been several delegates who have found the whole concept both new and slightly incomprehensible. One reason for this has been the Headwater Control practice of trying to bring together scientists, practitioners, policy-makers and non-government environmentalist organisations. The group's larger meetings have always been federal gatherings. Sponsorship has been shared with invited participation from associations representing hydrological science, soil conservation, erosion control, forestry, environmental activism and so forth. These delegations may have included fellow travellers in the work to protect headwater environments, but their main concerns have not necessarily coincided with the Headwater Control group's prescriptions for the environmental regeneration of headwater regions. The Liberec Workshop, whose proceedings are distilled into this volume, provided a first opportunity for the scattered supporters of Headwater Control to talk among themselves and fmd out to what degree there really is a shared vision of the way forward in headwater management, restoration and protection.

Book Description
This paper reviews perceived notions of the relationships between catchment land use and hydrology and explores whether much of the widely disseminated folklore, so often inextricably linked with issues of land use, is based on myth or reality. Gaps in our knowledge of the underlying processes in relation to land use and hydrology are identified. Our ability to apply this knowledge at different scales ranging from the plot to the catchment and regional scales are discussed and specific examples are drawn from Indian and African case studies. Methods for linking spatially distributed land-use hydrological models with economics and ecology through decision support systems are outlined and proposed as a framework for the integrated management of land and water developments at the catchment scale.

Book Description
Climate change is expected to modify the hydrological cycle and affect freshwater resources. Groundwater is a critical source of fresh drinking water for almost half of the world’s population and it also supplies irrigated agriculture. Groundwater is also important in sustaining streams, lakes, wetlands, and associated ecosystems. But despite this, knowledge about the impact of climate change on groundwater quantity and quality is limited. Direct impacts of climate change on natural processes (groundwater recharge, discharge, storage, saltwater intrusion, biogeochemical reactions, chemical fate and transport) may be exacerbated by human activities (indirect impacts). Increased groundwater abstraction, for example, may be needed in areas with unsustainable or contaminated surface water resources caused by droughts and floods. Climate change effects on groundwater resources are, therefore, closely linked to other global change drivers, including population growth, urbanization and land-use change, coupled with other socio-economic and political trends. Groundwater response to global changes is a complex function that depends on climate change and variability, topography, aquifer characteristics, vegetation dynamics, and human activities. This volume contains case studies from diverse aquifer systems, scientific methods, and climatic settings that have been conducted globally under the framework of the UNESCO-IHP project Groundwater Resources Assessment under the Pressures of Humanity and Climate Change (GRAPHIC). This book presents a current and global synthesis of scientific findings and policy recommendations for scientists, water managers and policy makers towards adaptive management of groundwater sustainability under future climate change and variability.
