Please accept this brief foreword that aims to syn- thesize and shine light upon this important book: Coasts, estuaries, and lakes are critical zones globally where humans interact and often conflict with nature. These Earth features are complex in morphology and inherently dynamic as a result of a multitude of processes that shift their form and change their functioning. Communities depend on the water and shoreline for sus- tenance, revenue, and countless aspects of life. The challenges of living in coastal zones, of both lakes and marine areas, are ever increasing as shoreline populations continue to climb and demand for food and financial sustainability increases. Moreover, climate change is creating new threats and perturbations that require humanity and governments to react, often rapidly, to water surpluses or shortages or shifting land and seascapes. Research is required to advance our understanding of these complicated systems and human impacts, and around the world, people must strive to share insights and to learn from each other. Beyond research, communities need wise planning and smart public and private action that is rooted in and driven by science. In addition to reading and studying about Earth processes and systems, scientists and students are encouraged to engage with governments and communi- ties to help them understand our evolving world and guide careful decision-making. The book Coasts, Estuaries and Lakes: Implications to Sustainable Development is an excellent collection of 29 chapters in 7 parts that delve into critical science and related challenges. From processes to pollutants, the chapters examine fundamental aspects, but are too numerous and detailed to review or attempt to synthesize suc- cinctly here. Led by Dr. N. Jayaraju from the Department of Geology at Yogi Vemana University, the experienced editorial team includes Drs. Sreenivasulu, Madakka, and Manjulatha. Part I addresses two immediate and important topics, flooding and pollution. Water quality and sedimentary aspects are explored in Parts II and III, respectively. Parts IV and V address biodiversity and climate change which are key concerns for coasts, estuaries, and lakes, and Parts VI and VII exam- ine socioeconomic considerations and geospatial tools that are essential to and will vii viii Foreword inform sustainable development. The compilation of papers is truly impressive, cov- ering a wealth of information and including examples at varying scales – from local and national studies in India, Kuwait, and elsewhere to global insights from past and recent work. In summary, the book collection will provide an excellent resource for years to come, and the various chapters will serve as invaluable references for experts and students around the world. The unfortunate reality is that our coasts, estuaries, and lakes are facing unprecedented challenges. Science must be used in partnership with continuous stakeholder engagement and wise governance to allow our shores and seas to sustain society for future generations. Director, Coastal Resources Center & Professor J. P. Walsh Graduate School of Oceanography, URI-GSO Bay Campus, Narragansett, RI, USA Foreword Coasts, estuaries and brackish lakes support an important biodiversity and large human populations, and they deliver many ecosystem services from which society gains goods and benefits. However, at the same time, they are the sites of many hazards which give rise to risks and threats to natural and human populations. These threats have been summarised as a “triple whammy” – that the areas are subject to three major threats: an increasing urbanisation and industrialisation; an increasing use of resources such as fish, water and space; and a decreasing resistance and resil- ience to external, wide-ranging factors such as climate change. These threats and risks may be even greater in developing countries which may have a lesser capabil- ity to deal with them. Given the above features, there is the need to summarise the characteristics of all areas and to gain better information and data to help us manage the areas sustain- ably. In this way, both nature and society benefit from a healthy environment. This requires natural and social scientists to work together and to work with policymak- ers and policy implementers. It requires gathering knowledge and data at local, regional, national and global levels and summarising these for a greater benefit. It requires us to be clear about why we need information and how it can be used, often based on studying and monitoring the areas. Against this background, in its five parts, this book integrates the science and management and gives attention to various features for many Indian areas, includ- ing hot spots within those, although other geographical locations are also men- tioned. The editors and many authors have done an excellent job of bringing together information and data on local and regional processes and dynamics. These cover sediment contamination and its effects, and coastal flooding, thereby covering physico-chemical interactions, water quality and hydrological processes for the coastal and catchment areas. Using evidence from various regions, and as well as on different spatial scales, it covers temporal scales including long-term natural and anthropogenic forcing on marine, coastal and estuarine ecosystems and multi-year biogeochemical observations. ix x Foreword It is axiomatic that we cannot understand the ecological structure and function- ing of an area unless we understand the physical and chemical structure and interac- tions. Hence the book covers saline water intrusion, and sediment physical, chemical and geochemical features. The seasonal and spatial features of local beaches, the substratum and suspended sediment dynamics and mineral chemistry give a back- ground to a greater understanding. This in turn will enable environmental manage- ment which has to be based on fit-for-purpose science and good analytical techniques, which are also described. The physical and chemical background then allows an interrogation of the bio- logical and ecological features. As such, the contributors give the background with greater information on biodiversity and ecology. The chemical conditions then result in contamination of the biota, reflected here in studies on a range of taxa from foraminifera to molluscs and fishes. This contamination often leads to pollution effects, defined as a decline in the health of organisms, their populations and com- munities, and indeed a reduction in their fitness-for-survival. Understanding these aspects requires us to define and apply bioindicators and follow this with detailed monitoring. As shown here, chemical contamination can have biochemical effects in organisms and lead to the sequestration of the contaminants in shells and other hard structures of organisms. As shown in this book, the features of an area may be affected by pressures, defined as the mechanisms of change on the natural and human systems. These may relate to local factors and activities, such as industrial discharges, leading to what may be termed endogenic managed pressures, where the causes and consequences of environmental change both occur in a given area being managed. However, all areas are also exposed to what may be called exogenic unmanaged pressures, in which the causes of change are outside the area being managed but the consequences have to be managed locally. The most important example of this is global climate change which may be manifest as alterations in weather patterns, storminess, sea- level rise, flooding and erosion, all of which increase the vulnerability of our coasts, estuaries and brackish lakes. Hence, although the causes of climate change have to be managed on a global scale, the consequences have to be managed locally. The editors and contributors summarise these local, regional and global effects and look at the implications of climate change for the geographical regions covered by the book. These features are important and so have an interest beyond the local areas. In particular, it is important for all natural and social scientists and policy- makers to understand such changes in wider global areas. Because of this, the book will be of interest to coastal and estuarine scientists worldwide.
