Learn estuaries ecosystems with free interactive flashcards. Unfortunately, in the past few hundred years, we have lost more than half of the wetlands in the United States. Estuaries are vital to both ecological health and the economy, as they provide habitat for many kinds of marine life and commercially important species such as oysters. Many estuaries, as is the case with the four TIDE estuaries, are of tremendous economic and social importance as they are the main trade hub for international shipping, attracting industrial production and transport companies, providing labor and economic growth. Today, estuaries are a tremendous economic resource which provides jobs and resources to coastal communities. For our regions to grow and reach their economic potential, we must also support good health of our estuaries. Estuaries transport and trap nutrients and sediment through the combined action of freshwater flow, wind, waves and tidal action. Editedby Linwood H. Pendleton. South Africa is well endowed with estuaries, having roughly 255 functioning estuaries along its ap-proximately 3 100 km of coastline. Ecosystem Services Estuaries can filter out sediments and pollutants from rivers and streams before they flow into the ocean, providing cleaner water for humans and marine life. The economic rationale underlying these concerns is not so much that there has been a deterioration in estuary service levels as that the services yielded by the estuaries have strong public good properties and that key relevant public policy makers have seemed Ecological- Climate moderation, nutrient cycling, waster treatment, and food control Economic- Food, drinking water, irrigation water, and hydroelectricity. Yet, the economic value of these ecosystem services is unknown. Economic benifits of estuary system 1. Many species of fish, crabs, and shellfish, which live in estuaries for part or all of their lives, provide essential food for humans. Producedby. TheEconomic and MarketValue of Coastsand Estuaries: What’sAt Stake? In collaboration with the National Institute of Water and Atmospheric Research (NIWA), we are exploring how to develop maps of ecosystem services in our estuaries. Estuaries provide critical services to the long-term wellbeing of all Western Australians, but their capacity to sustain these services is dependent on their physical condition and ecological health. Tourism Fisheries and other commercial activities thrive on the wealth of natural resources estuaries supply. 1. Estuary, partly enclosed coastal body of water in which river water is mixed with seawater.In a general sense, the estuarine environment is defined by salinity boundaries rather than by geographic boundaries. The natural functioning of coastal ecosystems is needed to produce and sustain the vital flow of various goods and services to humans. 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. The economic impact of this ecosystem is being explored in two phases, the first one providing an overview of the ecotourism and ... Ecosystem Services ..... 22 Table 3. The health of estuary ecosystems is threatened by: 1. increased nutrients and algal blooms 2. loss of habitat and biodiversity 3. contaminants and pollutants 4. accelerated rates of sedimentation 5. disturbance of acid sulfate soils 6. changes to freshwater and tidal flows 7. invasive species 8. climate change. Wetlands provide several ecosystem services such as reducing erosion, recharging aquifers and providing habitat for several wildlife species. Estuaries maintain water quality – benefiting people and marine life. Verloren Estuary: 1 895: Western Cape, north of Cape Town The protected coastal waters of estuaries also support important public infrastructure, serving as harbors and ports vital for shipping and transportation. Estuaries are productive systems which provide a valuable supply of goods and services, ranging from fisheries to recreational opportunities, but there have been no previous attempts to estimate the economic value of these ecosystem services, with the result that their contribution to the national economy has been under-appreciated. Photo Credit: Nanette O'Hara Estuaries have important commercial value and their resources provide economic benefits for tourism, fisheries and recreational activities. This article summarizes four integrated economic studies undertaken to contribute to resource preservation and restoration decisions for the Peconic Estuary System of Suffolk County, NY. Estuaries provide important environmental, social, cultural, and economic services. An estuary may also be called a bay, lagoon, sound, or slough. RestoreAmerica's Estuaries An estuary is an area where a freshwater river or stream meets the ocean. Professor Pauline Ross, who leads the research group in the School of Life and Environmental Sciences, said: "Estuaries provide services of immense ecological and economic value. Estuaries have an important commercial value. The river is approximately 294 km long with a catchment area of 7 715 km 2. In addition to their biological importance, estuaries also have significant cultural and economic values. They are ideal places for boats or ships to come in to land and so are used for transport. The Berg estuary (32° 46’ S; 18° 09’E) drains into the Atlantic Ocean, and is located in the Western Cape and is found on the west coast, north of the coastal city of Cape Town, in fact north of Saldanha Bay. Bays & Estuaries Texas has 367 miles of coastline within which 21 river basins terminate, bringing fresh water from surface run-off, rivers, and streams into individual bays. However, increasing threats from both human activities and environmental c… Healthy estuaries can absorb surges of water from storms, floods, and tides, protecting our homes and communities. Coasts and Estuaries: The Future provides valuable information on how we can protect and maintain natural ecological structures while also allowing estuaries to deliver services that produce societal goods and benefits. What major ecological and economic services do fresh-water systems provide? Cultural and economic aspects of estuaries. The Nueces Estuary is located on the Texas Coastal Bend in San Patricio and Nueces Counties, adjoining the city of Corpus Christi.It is fed by the Nueces River and Oso Creek and separated from the Gulf of Mexico by Mustang Island. The term estuary is derived from the Latin words aestus (“the tide”) and aestuo (“boil”), indicating the effect generated when tidal flow and river flow meet. MAPPING ECOSYSTEM SERVICES IN ESTUARIES The Waikato Regional Policy Statement (2016) identifies the importance of recognising and maintaining or enhancing ecosystem services. Most of the worlds largest cities have been build on estuaries. These early developing towns and cities took advantage of the food availability, effective waste disposal, and high quality of life that estuaries provided. 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. In general, the term ‘ecosystem services’ refers to the benefits people obtain from ecosystems. Their resources provide tourism, fisheries and recreational activities to have a greater economic benefit. Economic Benefits of Estuaries Jerico Paulo Lim 2. They have significant commercial value supporting industries such as tourism, fisheries and recreational facilities. In estuaries, the salty ocean mixes with a freshwater river, resulting in brackish water.Brackish water is somewhat salty, but not as salty as the ocean. Water continually circulates into and out of an estuary. It is intended that a more comprehensive study will be undertaken in the near future that will adopt more rigorous research techniques utilising the available scientific information about the environmental services provided by estuaries and will embark benefits of the Everglades Watershed and estuaries. Coastal marshes and wetlands provide ecosystem services that are critical to coastal communities and economies worldwide. Much of the local economy surrounding the Tillamook Bay estuary is provided by the coastal ecosystem: the area is a hotspot for coastal birding, home to a rich diversity of marine fish and wildlife, and a prized location for harvesting bay clams and culturing oysters. Here, bounded by barrier islands, the mixing of freshwater and seawater in these bays forms estuaries. These issues are addressed through chapters detailing case studies from estuaries and coastal waters worldwide, presenting a full range of natural variability and human pressures. Estuaries and bays form where rivers meet the ocean, mixing freshwater from far inland with saltwater from the Gulf of Mexico.. An estuary is defined as a partly enclosed body of water along the coast where one or more streams or rivers enter and mix freshwater with seawater. Industry is often set up near estuaries for ease of transportation of goods (for example, fisheries and timber). Estuaries exhibit a wide array of human impacts that can compromise their ecological integrity, because of rapid population growth and uncontrolled development in many coastal regions worldwide.
