why are coastal areas densely populated

The average population density in coastal areas is about 80 persons per square kilometer, twice the world’s average population density. National Geographic Headquarters In the United States, the National Oceanographic and Atmospheric Administration has developed the Coastal Assessment Framework, which uses census data and mapping programs to provide managers and analysts with a watershed-based system for collecting and organizing resource-use data and developing coastal management strategies.37 Many problems with water quality and ecosystems are best solved at the watershed level, which encompasses the full area that drains into a particular body of water. Point out the East Coast and West Coast. Many coastal areas are densely populated, but a large expanse of coastal areas are hardly populated at all. First, the project conducted an environmental site assessment to obtain data on coastal environmental conditions, resource management practices, population dynamics, and community attitudes toward both population and environmental issues. Kenya, Liberia, the Philippines, and Puerto Rico, have lost over 70 percent of their mangroves.14. Contaminants and activities that destroy coastal habitats and ecosystems also contribute to the loss of the marine fauna on which many people rely for food and income. Brian Voigt, “Glossary of Coastal Terminology” (March 1998), accessed online at www.csc.noaa.gov/text/glossary.html, on Aug. 15, 2003; Organization for Economic Cooperation and Development (OECD). Tide gauge stations from around the world have measured the daily high and low tides for more than a century, using a variety of manual and automatic sensors. Ask: Do more people live near the coasts or away from the coasts? Then explain to students how they can tell where many people live and where few people live. Some densely-populated areas in the Netherlands, England, Germany and Italy already lie below the mean high-water mark. Tourism, fishing, and aquaculture are industries with major economic influences on coastal ecosystems. More than 100 countries — many of them small islands — rely on the resources that coral reefs provide.1 But coral reefs are increasingly threatened by human activity, particularly in developing countries. Flood control is an important issue for the Netherlands, as due to its low elevation, approximately two thirds of its area is vulnerable to flooding, while the country is densely populated.Natural sand dunes and constructed dikes, dams, and floodgates provide defense against storm surges from the sea. Efforts to balance local interests with national legislation need to consider the socioeconomic context of coastal populations and what role demographic patterns play in the region. Most are based on an area within 60 to 200 kilometers of the shoreline and may include coastal floodplains, coastal forests called mangroves, marshes, and tideflats (coastal areas affected by the rise and fall of the tide), as well as beaches, dunes, and coral reefs.1 The term “coastal regions” also covers marine fisheries because the bulk of the world’s marine fish harvest is caught or reared in coastal waters.2 Coastal areas help prevent erosion; filter pollutants; and provide food, shelter, breeding areas, and nursery grounds for a wide variety of organisms. The United Nations Environment Programme estimates that South Asian waters are at the highest risk of pollution: 825 million people in the region do not have basic sanitation services.23 In Mumbai, India, for instance, almost half of the city’s 12 million residents are either slum dwellers or homeless with little access to sewage and sanitation facilities. Washington, DC 20036, National Geographic Society is a 501 (c)(3) organization. because many populated areas are located near the coasts. These challenges are particularly acute for island countries, where coasts often comprise the entire territory.6 Such countries may also be threatened by rising sea levels, a possible consequence of climate change. When concentrated in small, confined, and overcrowded areas such as coastal zones, pollution and other problems pose greater threats to human health.

Verlaan, “The Importance of Coastal Management to Human Health,” in, World Bank Group, “Sewage Disposal Project Transforming Urban Environment and Improving Quality of Life in Mumbai, India” (1999), accessed online at http:// lnweb18.worldbank.org/sar/sa.nsf/, FAO, “Coastal Zone Management and Equality Between Women and Men” (1998), accessed online at www.fao.org/sd/epdirect/. Students compare several maps to explore relationships between high and low population density, transportation corridors, climate, and land cover in the United States. By discharging ballast water near the islands, large vessels and smaller fishing boats have introduced nonindigenous plant and animal species to the islands’ coasts.9 The situation in the Galapagos Islands also highlights how migration can contribute to the depletion of natural resources. At least 107 of the world’s 134 coastal developing nations are involved in some type of ICM effort at the national or subnational level.33 In general, the most successful ICM efforts share several characteristics: Managing coastal areas requires concerted multisectoral efforts by government institutions at all levels, the private sector, and community groups, as well as sustained political support.
