| Résumé : |
Increases in the human population over the past 50 years have had severe global effects on river systems through enhanced fertilizer usage, damming, deforestation, and many other land-use changes. Many countries in the world are experiencing potable and agricultural water shortages. The coastal ocean is a dynamic region where rivers, estuaries, ocean, land, and the atmosphere interact. Although relatively small in area, this region, having 30 percent of the total net oceanic productivity, supports as much as 90 percent of the global fish catch. By 2025 an estimated 75 percent of the world's population is expected to live in this coastal zone, with many of the remaining 25 percent living near major rivers. One of the mos challenging issues concerning large river fluxes is to better understand the major changes that they have undergone due to human influence as a result of land-use changes (agricultur and urbanization) and river basin and delta alterations, and the resultant impact of these changes on land-ocean material transfer, both quantitatively and qualitatively. River systems play an important role (via the carbon cycle) in the natural self-regulation of Earth's surface conditions by serving as a major sink for anthropogenic CO2. Approximately 90 percent of global carbon burial occurs in ocean margins, with the majority of this thought to be buried in large delta-front estuaries (LDEs).
This volume provides a state-of-the-art summary of biogeochemical dynamics at major river-coastal interfaces for advanced students and researchers. It provides information on how humans have altered carbon cycling, sediment dynamics, CO2 budgets, wetland dynamics, and nutrients and trace element cycling at the land-margin interface. Many of the globally important LDEs are discussed across western and eastern hemispheres from a perspective that addresses the fluxes and cycling of water and sediment dynamics, from source to sink. These systems span a range pf latitudes, elevations, and climates in the drainage basin, coastal oceanographic settings, and nature and degrees of human alteration. It is this breadth of examination that provides the reader with a comprehensive understanding of the overarching controls on major river biogeochemistry. |
