Economics of Estuaries. Estuaries, the transition zones where rivers meet the sea, provide the focal point around which coastal communities grow. The local bay or sound nurtures a high quality of life and maintains the health and traditions of our communities. An estuary is also a tremendous economic resource which provides jobs to coastal. Estuaries provide important environmental, social, cultural, and economic services. The provision of these services is often negatively impacted by urban development within the catchment and along shorelines, most notably through habitat loss and alteration of hydrological and sedimentation regimes influencing system structure and function. Despite the importance of this coastal protection service, very few economic studies have estimated a value for it. Those studies that do exist tend to use benefit transfer and replacement cost methods of valuation in an ad hoc manner, which undermine the reliability of the value estimates (see Chong and Barbier for further discussion).Cited by: Social value. Estuaries are one of the most important of the state's natural resources and are some of the most intensively used areas of NSW. Over 80% of the population live in the coastal zone and coastal and estuarine environments are of great cultural and economic importance to the general community. The protected coastal waters of.

  We integrated the emerging information of the ecological, economic and social importance of the coasts at a global scale. We defined coastal regions to range from the continental shelf (to a depth of m), the intertidal areas and adjacent land within km of the coastline. 5. MAXIMISING THE ECONOMIC VALUE OF ESTUARIES_____16 Introduction 16 Aligning the vision to economic importance 16 Identify values and their regional importance 16 Understand compatibility and trade-offs 16 Agree on a broad vision of the type of development on the estuary . Estuaries have an important commercial value. Their resources provide tourism, fisheries and recreational activities to have a greater economic benefit. The protected coastal waters of estuaries also support public infrastructure such as harbors and ports which are a . n the Atlantic coast, estuaries are among the most important coastal features, both ecologically and with respect to human settlement and use (Environment Canada, ). Estuaries are semi enclosed bodies of water formed when fresh water from rivers and coastal streams flows into and mixes with salt water of .

made by different types of estuaries; • To estimate the contribution that estuarine and estuary-dependent fishes make to the economic value of estuarine and marine catches. • To give rough estimates of the status of stocks of important estuarine fish species; and • To comment on the implications of the above findings for estuary management.   Estuarine Ecology, Second Edition, covers the physical and chemical aspects of estuaries, the biology and ecology of key organisms, the flow of organic matter through estuaries, and human interactions, such as the environmental impact of fisheries on estuaries and the effects of global climate change on these important ecosystems.   Estuaries have economic benefits for tourism and fisheries. In its protected form, an estuary acts as harbor-a vital place for shipping, transportation and industry. It facilitates healthy ocean environments as most of the pollutants, mud and sediments from the river streams are filtered out before the water join the sea providing clean water. • estuaries are important, highly productive habitats at the sea-land interface • estuarine populations and communities are structured both by strong abiotic influences (e.g., salinity gradients) and biotic interactions (e.g., competition, predation, facilitation).
