Green Technologies For Sustainable Water Management

The 28 chapters in this collection describe science-based principles and technological advances behind green technologies that can be effective solutions to pressing problems in sustainable water management.

Our Earth is considered as a natural system which organizes and controls itself. However, the present scale of anthropogenic activity is unprecedented in the history of mankind compelling the intelligentia to ponder over the scientific causes of the problems, processes and sustainable and pragmatic solutions. The current rate of resource use and consumption pattern are depleting the planet’s finite resources and damaging life-supporting ecosystems. A large number of toxic substances are increasingly found in air, water, soil, and flora and fauna. We are in the midst of a period of increasing interconnected and complex global challenges that seek action across temporal and spatial scales, diverse sectors, and concerted efforts from global citizens. The environment on account of human’s action has been experiencing imbalances and ecological catastrophe. Environmental issues like global climate change, biodiversity loss, the rapid depletion of natural resources, degradation of global commons, stratospheric ozone depletion have been restricting the safe operating space and transgressing the planetary boundaries endangering the existence of human societies. The global environmental problems if not scientifically managed may end up in the civilizational collapse. Nevertheless, the underlying commonality among these environmental issues is interrelatedness, complexity, and difficulty in identifying and implementing solutions. The global environmental challenges can be managed by adopting sustainable green technologies which dovetails the principles of environmental sustainability with social and ecological sustainability. Green growth is construed as a new development paradigm that sustains economic growth while at the same time ensuring environmental sustainability.

Contributing to the growing debate on the need for sustainable water use and management, with concrete examples of new approaches, concepts, arguments, methods and findings which illustrate how this can be achieved, this book will be attractive for large groups of readers familiar with one or more of the themes it tackles, and to the general public. Within this context, the book makes use of many tables and graphics, which bring the many messages together. This approach is intended not only for those working on water matters (e.g. bureaucrats, water managers, policymakers, journalists, etc.) and interested in water management issues and sustainability at large, but also for students of water management, water politics, environmental policy, water economics, water engineering and sustainability studies. Located at the crossroads of two key phenomena: sustainability and water, this book brings forward academic research and discussions on water efficiency, new technologies, and the water-agriculture nexus. It also benefits readers by tackling matters related to trans-boundary cooperation on water (including rainwater) and river-basin management, pricing issues, participatory water management, and the role of women in sustainable water use, amongst others.

In the present scenario, green technologies are playing significant role in changing the course of nation’s economic growth towards sustainability and providing an alternative socio-economic model that will enable present and future generations to live in a clean and healthy environment, in harmony with nature. Green technology, which is also known as clean technology, refers to the development and extension of processes, practices, and applications that improve or replace the existing technologies facilitating society to meet their own needs while substantially decreasing the impact of human on the planet, and reducing environmental risks and ecological scarcities. The concepts of Green Technologies, if endorsed and pervaded into the lives of all societies, will facilitate the aim of the Millennium Development Goals of keeping the environment intact and improve it for the civilization to survive. Green Technologies and Environmental Sustainability is focused on the goals of green technologies which are becoming increasingly important for ensuring sustainability. This book provides different perspectives of green technology in sectors like energy, agriculture, waste management and economics and contains recent advancements made towards sustainable development in the field of bioenergy, nanotechnology, green chemistry, bioremediation, degraded land reclamation. This book is written for a large and broad readership, including researchers, scientists, academicians and readers from diverse backgrounds across various fields such as nanotechnology, chemistry, agriculture, environmental science, water engineering, waste management and energy. It could also serve as a reference book for graduates and post-graduate students, faculties, environmentalist and industrial personnel who are working in the area of green technologies.

This book focuses on green and innovative wastewater treatment technologies that promote sustainability. It discusses a variety of biological, physical, and chemical treatment technologies. It covers biological processes for recovery of value-added products from wastewater and gives an overview of enzymatic hydrolysis and bioremediation of wastewater using immobilized enzyme and fungus. It offers a case study and future trends of wastewater treatment through membrane bioreactor technologies, describes advanced chemical–physical processes for recalcitrant pollutant, and emphasizes the use of low-cost materials and cost-effective treatment methods.

Development of advanced technologies is a critical component in overcoming the looming water crisis. Stressing emerging technologies and strategies that facilitate water sustainability for future generations, the second volume in the two-volume set Sustainable Water Management and Technologies provides current and forthcoming technologies research, development, and applications to help ensure availability of water for all. The book emphasizes emerging nanotechnology, biotechnology, and information technology applications as well as sustainable processes and products to protect the environment and human health, save water and energy, and minimize material use. It also discusses such topics as groundwater transport, protection, and remediation, industrial and wastewater treatment, reuse, and disposal, membrane technology for water purification and desalination, treatment and disposal in unconventional oil and gas development, biodegradation, and bioremediation for soil and water. Stresses emerging technologies and strategies that facilitate water sustainability. Covers a wide array of topics including drinking water, wastewater, and groundwater treatment, protection, and remediation. Discusses oil and gas drilling impacts and pollution prevention, membrane technology for water desalination and purification, biodegradation, and bioremediation for soil and water. Details emerging nanotechnology, biotechnology, and information technology applications, as well as sustainable processes and products.

While the world’s population continues to grow, the availability of water remains constant. Facing the looming water crisis, society needs to tackle strategic management issues as an integrated part of the solution toward water sustainability. The first volume in the two-volume set Sustainable Water Management and Technologies offers readers a practical and comprehensive look at such key water management topics as water resource planning and governance, water infrastructure planning and adaption, proper regulations, and water scarcity and inequality. It discusses best management practices for water resource allocation, ground water protection, and water quality assurance, especially for rural, arid, and underdeveloped regions of the world. Timely topics such as drought, ecosystem sustainability, climate change, and water management for shale oil and gas development are presented. Discusses best practices for water resource allocation, ground water protection, and water quality assurance. Offers chapters on urban, rural, arid, and underdeveloped regions of the world. Describes timely topics such as drought, ecosystem sustainability, climate change, and water management for shale oil and gas development. Covers water resource planning and governance, water infrastructure planning and adaptation, proper regulations, and water scarcity and inequality Discusses water resource monitoring, efficiency, and quality management.
