Humans have had a long relationship with the ebb and flow of tides on river deltas around the world. The fertile soils of river deltas provided early human civilizations with a means of farming crops and obtaining seafood from the highly productive marshes and shallow coastal waters associated with deltas. However, this relationship has at times been both nurturing and tumultuous for the development of early civilizations. The vicissitudes of seasonal changes in river flooding events as well as frequently shifting deltaic soils made life for these early human settlements challenging. These natural transient processes that affect the supply of sediments to deltas today are in many ways very similar to what they have been over the millennia of human settlements. But something else has been altered in the natural rhythm of these cycles. The massive expansion of human populations around the world in both the lower and upper drainage basins of these large rivers have changed the manner in which sediments and water are delivered to deltas. Because of the high density of human populations found in these regions, humans have developed elaborate hydrological engineering schemes in an attempt to "tame" these deltas. The goal of this book is to provide information on the historical relationship between humans and deltas that will hopefully encourage immediate preparation for coastal management plans in response to the impending inundation of major cities, as a result of global change around the world.

There is increasing understanding, globally, that climate change will have profound and mostly harmful effects on human health. This authoritative book brings together international experts to describe both direct (such as heat waves) and indirect (such as vector-borne disease incidence) impacts of climate change, set in a broad, international, economic, political and environmental context. This unique book also expands on these issues to address a third category of potential longer-term impacts on global health: famine, population dislocation, and conflict. This lively yet scholarly resource explores these issues fully, linking them to health in urban and rural settings in developed and developing countries. The book finishes with a practical discussion of action that health professionals can yet take.

Biogeochemistry of Estuaries offers a comprehensive and interdisciplinary approach to understanding biogeochemical cycling in estuaries. Designed as a text for intermediate to advanced students, this book utilizes numerous illustrations and an extensive literature base to impart the current state-of-the-art knowledge in this field. While many of the existing books in estuarine science are comprised of edited volumes, typically focused on highly specific topics in estuaries,Biogeochemistry of Estuaries provides, for the first time, a unique foundation in the areas of geomorphology, geochemistry, biochemistry, aqueous chemistry, and ecology, while making strong linkages (trhoughout the text) to ecosystem-based processes in estuarine sciences. Estuaries, located at the interface between land and the coastal ocean are dynamic, highly productive systems that, in many cases, have been historically associated with development of many of the great centers of early human civilization. Consequentially, these systems have and continue to be highly impacted by anthropogenic inputs. This timely book takes the foundational basis of elemental cycling in estuarine and applies it to estuarine management issues. Biogeochemistry of Estuaries will be welcomed by estuarine/marine scientists, ecologists, biogeochemists, and environmentalists around the world.

On Shishmaref Island in Alaska, homes are being washed into the sea. In the South Pacific, small island nations face annihilation by encroaching waters. In coastal Louisiana, an area the size of a football field disappears every day. For these communities, sea level rise isn’t a distant, abstract fear: it’s happening now and it’s threatening their way of life. In The Rising Sea, Orrin H. Pilkey and Rob Young warn that many other coastal areas may be close behind. Prominent scientists predict that the oceans may rise by as much as seven feet in the next hundred years. That means coastal cities will be forced to construct dikes and seawalls or to move buildings, roads, pipelines, and railroads to avert inundation and destruction. The question is no longer whether climate change is causing the oceans to swell, but by how much and how quickly. Pilkey and Young deftly guide readers through the science, explaining the facts and debunking the claims of industry-sponsored “skeptics.” They also explore the consequences for fish, wildlife—and people. While rising seas are now inevitable, we are far from helpless. By making hard choices—including uprooting citizens, changing where and how we build, and developing a coordinated national response—we can save property, and ultimately lives. With unassailable research and practical insights, The Rising Sea is a critical first step in understanding the threat and keeping our heads above water.

The Mekong Delta of Vietnam is one of the most productive agricultural areas in the world. The Mekong River fans out over an area of about 40,000 sq kilometers and over the course of many millennia has produced a region of fertile alluvial soils and constant flows of energy. Today about a fourth of the Delta is under rice cultivation, making this area one of the premier rice granaries in the world. The Delta has always proven a difficult environment to manipulate, however, and because of population pressures, increasing acidification of soils, and changes in the Mekong’s flow, environmental problems have intensified. The changing way in which the region has been linked to larger flows of commodities and capital over time has also had an impact on the region: For example, its re-emergence in recent decades as a major rice-exporting area has linked it inextricably to global markets and their vicissitudes. And most recently, the potential for sea level increases because of global warming has added a new threat. Because most of the region is on average only a few meters above sea level and because any increase of sea level will change the complex relationship between tides and down-river water flow, the Mekong Delta is one of the areas in the world most vulnerable to the effects of climate change. How governmental policy and resident populations have in the past and will in coming decades adapt to climate change as well as several other emerging or ongoing environmental and economic problems is the focus of this collection.
