Salt marshes are vitally important coastal ecosystems that filter water, buffer against storm erosion, and provide essential nursery habitat for important fishery species. Long thought to be resistant to ecological perturbations, salt marshes are now known to be highly sensitive indicators of environmental change and impacts. This state-of-the-science volume details how humans have modified salt marshes around the world and why these critical habitats desperately need protection. It also offers clear recommendations about what should be done to re mediate current threats and restore the structure and function of salt marsh ecosystems.
With the increasing influence of science and technology (S&T) on socioeconomic life and public affairs, there has been a growing demand for S&T expertise in today's public decision-making.
The National High Technology Research and Development Program (863 Program), involving hundreds of S&T experts, marked the beginning of a new journey for China's high-tech development. This book discusses China's S&T decision-making mechanism, with the 863 Program as the central case and scientist' influence on public decision-making as the focus. More importantly, it extracts three key elements to analyze the determinative factors behind that influenceÂ - knowledge, value and institutions, and proposed a KIV framework of macro-analysis.
The KIV, being the first framework to generalize factors that could affect scientists' influence on public decision-making, is of both theoretical significance and innovative value. In addition, by finding out those factors, this book attempts to create a decision-making environment conducive to scientists' contribution of their knowledge.
This book entitled "Environmental Impact Assessment and Management," embodies 15 chapters covering a wide spectrum. Chapter 1 contains details of EIA, Basic elements and Methodologies. Further, important guidelines to be followed before establishing industries, water related projects and transport related projects are narrated in Chapter 2. Important case studies of EIA viz, second stage expansion of Malpe fishing harbour, Human impact on Himalayan Ecosystem, Konkan Railway Project, Heavy metal pollution in the Coovum river, an impact prediction for an irrigation project and impact of cement making on the air quality of Coimbatore, are dealt in Chapter 3. Once a project comes into existence, it results in side effects of the immediate environment which are evident on the consecutive 5-10 years of operation. Therefore, its efficiency and pollution abatement systems should be checked and corrected in a manner similar to financial auditing and this aspect has been incorporated in Chapter 4. Now-a-days due to the rapid process of urbanization, all the cities of India have accumulated a lot of filth leading to ghasty smell, loss of property value and the spread of diseases. In order to have a clean environment, we have to have a systematic refuse management package for Indian conditions. As illustrations of this view, the urban solid waste management in Hyderabad, Shimoga and Rourkee cities have been explained in the Chapter 5 and 6 respectively. The consecutive chapters deal on various other aspects such as coastal zone management, deforestation, impact of mining on fisheries, wild life management, termite pest control, bioremediation of wastes by hydrophytes, role of remote sensing in EIA, Kaiga environment and management of food protection.
