Water In The Green Economy
Abstract
Water and its management is becoming not just a local but a global priority. The UN Rio+20 Declaration emphasises the need to establish a green economy as the means to achieving sustainable development while protecting and improving the world’s natural resources. Water is increasingly seen as a central plank of the green economy. It is embedded in all aspects of development – food security, health, and poverty reduction – and in sustaining economic growth in agriculture, industry, and energy generation.

Watershed Water Environment And Hydrology Under The Influence Of Anthropogenic And Natural Processes
The major aims of this book, “Watershed Water Environment and Hydrology under the Influence of Anthropogenic and Natural Processes”, are to focus on innovative/new ideas on the watershed water environment from different perspectives across the field; distinguish the evolution of watershed water ecological and environmental quality; clarify the biogeochemical cycling of elements or pollutants; identify and quantify the sources of pollutants; and assess the ecological risk and human health risk of pollutants in the water environment at different watershed scales. In particular, eight peer-reviewed articles were collected, mainly reporting the hydrochemistry-based watershed weathering processes and their environmental implications, trace elements and their risks, and the nutrients cycle in river–reservoir systems. Overall, these papers contribute to several aspects of the watershed water environment and are valuable for river water resource protection and management.

Climate Variability and Change in the 21st Century.
Water resources management should be assessed under climate change conditions, as historic data cannot replicate future climatic conditions. - Climate change impacts on water resources are bound to affect all water uses, i.e., irrigated agriculture, domestic and industrial water supply, hydropower generation, and environmental flow (of streams and rivers) and water level (of lakes). - Bottom-up approaches, i.e., the forcing of hydrologic simulation models with climate change models’ outputs, are the most common engineering practices and considered as climate-resilient water management approaches. - Hydrologic simulations forced by climate change scenarios derived from regional climate models (RCMs) can provide accurate assessments of the future water regime at basin scales.

Environmental Impact and Remediation of Heavy Metals
Heavy metals are a group of metals and metalloids that includes transition metals, lanthanides, and actinides. When released into water, these elements have toxic effects on water quality and surface sediments, affecting environmental parameters such as pH and temperature. Therefore, metals that are harmful to aquatic and terrestrial ecosystems pose a significant threat to plants, animals, and human health. As such, there is increased interest in mitigating the harmful environmental impacts of heavy metals. This book provides a comprehensive overview of heavy metals, their impacts on water, soil, food crops, and cosmetics, and techniques for their remediation. It is organized into three sections: “Heavy Metals and Their Effects on the Environment,” “Evaluation of Heavy Metals and Their Risks to Irrigation Water,” and “Remediation of Heavy Metals.

Moving Toward Sustainability: Sustainable And Effective Practices For Creating Your Water Utility Roadmap
Introduction:
Sustainable water and wastewater services are critical to providing the American public with clean and safe water and helping ensure the environmental, economic, and social sustainability of the communities that utilities serve. Utilities across the country face tremendous challenges, such as aging infrastructure, an aging workforce, increasing mandates, and competing priorities within the communities they serve.
The purpose of this document is to assist utility leaders with implementing proven and effective practices over time to improve their operations and move toward sustainability, at a pace consistent with their needs and the needs of their communities. It provides utility leaders with a cohesive structure to help them address various challenges proactively and with confidence. The practices described in this document reflect the lessons learned and the practical experience utilities have derived as they have improved their operations. A utility can use this document to identify specific opportunities for improvement and draw on the example practices to create an individualized “roadmap” to more sustainable operations.
