The most serious concerns worldwide involve persistent organic pollutants (POPs), which can be transported in the atmosphere and have become common in the oceans. Phone: 800-877-9881 If no button appears, you cannot download or save the media. Damming rivers can also have negative environmental effects, such as soil erosion and destruction of ecosystems that support various fish and marine mammals. Baseline studies assessing the threats to coastal areas should include data on population and the environment, indigenous peoples’ concerns, applicable legislation and the agencies involved, gender concerns, and socioeconomic characteristics of the areas. Box 1 People who live in coastal regions may suffer the cumulative burden of environmental stress from the activities on and overcrowding of the coast and from upstream and inland development. The program focuses on understanding the structure and function of mangroves, seagrasses, and coral reefs, the primary coastal ecosystems in the Caribbean. https://www.answers.com/Q/Why_are_coastal_areas_so_densely_populated In the densely forested southern part of the region, which has historically been more difficult to develop, rural population densities are generally lower than in the open savanna. 3362 days since Next Geography Class!!! The population of the United States reached 300 million on October 17, 2006, said the U.S. Census Bureau. adapted from National Geographic Xpeditions lesson “Taking Care of Our Oceans”. As an example, point out the desert regions of the West and describe why few people live there. Using data from scores of stations around the world, scientists can calculate a global average and adjust it for seasonal differences. 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. Ask: Why do most people live near the coasts? Integrated coastal management (ICM), an internationally accepted approach to managing resources that is based on the United States’ 1972 Coastal Zone Management Act, allows policymakers and planners to take population issues into account when looking at the pressures, threats, and opportunities facing coastal areas. Code of Ethics. Demographic factors, especially migration, are major considerations in how people use coastal regions. Heavy population pressure on the coasts is causing more and more of the natural environment to be paved over or converted into ports, tourist beaches, and new communities. Several strategies can be used to incorporate population and gender dynamics in planning project activities: In the Philippines, for example, projects have used a combination of these models to build links across sectors. Terms of Service |  The most densely populated region is the Southeast (also called the Coastal Lowlands). Many species are overharvested because the world fishing fleet is larger than it needs to be. The average population density in coastal areas is about 80 persons per square kilometer, twice the world’s average population density. Not all urban areas are bastions of blue. The city statistics on this website use the urban centre boundaries 2015 from GHSL. How might global warming exacerbate coastal hazards? Without coastal defence mechanisms these would already be flooded today. Women were not consulted in this process and lost a vital source of household protein and income.30 Women usually have different access to and control over land and water in coastal zones: Fewer than 5 percent of beneficiaries of land reform in El Salvador and Honduras were women.31. The map shows that the most densely populated areas are along coastlines. Once they understood that population pressures were increasing sedimentation along the coast and threatening corals and fish, community members began reforestation projects on the coasts and inland and began to encourage the use of family planning services. Poor women depend especially heavily on fish and fishing. 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. In this 6 regions across India have been identified for measurements of population density. © 1996 - 2020 National Geographic Society. Washington, DC 20036, National Geographic Society is a 501 (c)(3) organization. Fishing or harvesting, the destruction of mangroves, and pollution and sedimentation from human activities all can affect the coastal environment. These fishermen sometimes unknowingly exacerbate a problem created by tankers and ocean liners. In spite of this widespread concern over sea level rise, no accurate worldwide estimate of the number of people likely to be affected by coastal inundation or flooding has been published. Videos and links. Ask: Do more people live near the coasts or away from the coasts? Sea level is measured by two main methods: tide gauges and satellite altimeters. Marine fisheries and aquaculture (the controlled cultivation and harvesting of freshwater and marine organisms) produce close to 100 million tons of fish, shellfish, and edible plants every year, providing a livelihood for about 35 million people, most of whom live in developing countries.18 Overharvesting to meet global consumers’ growing demand for seafood can deplete many species and alter the biological structure of coastal ecosystems. In addition, two-fifths of cities with populations of 1 million to 10 million people are located near coastlines.11 The urbanization of coasts brings with it coastal development (including demands for fresh water and sewage treatment) and damage to coastal ecosystems. 2. Population, density and education all play a role. It can lead to unsustainable coastal development as infrastructure is built on the shoreline to accommodate tourists. However, along the coast, population densities are driven up by a large number of coastal … Coral reefs worldwide are deteriorating at an alarming rate: As of late 2000, 27 percent were severely damaged, compared with 10 percent in 1992.2 More reefs are degraded and threatened by dynamite fishing, coral mining, and other human activities, as well as by bleaching caused by rising ocean temperatures. Population density tells us how many people live on one square kilometre of land.The world’s population is not spread evenly over the continents.Asia and Europe are the most densely populated continents.Many other areas of the world , like deserts, polar regions or high mountains are very sparsely ,or not at all populated .. About 90% of the earth’s people live on only 10% of the land. Students look at a map of population density in the United States, describe the pattern of settlement they see near the coasts, and brainstorm and draw possible reasons for it. CARICOMP is one example of a functioning international program for monitoring the coastal marine environment and can be used as a model for other countries or regions.38. Many of the world’s small island or isolated states have large populations for their size. Other problems include destructive harvesting methods such as trawling (dragging weighted nets across the sea floor to catch shrimp and bottom-dwelling fish), and bycatch (unintended catch of nontarget species).19 Modern trawling equipment scoops through sediment and rock and often kills the worms, sponges, and other species that live on the seafloor. Unless governments and users of coastal resources take action, population pressures and the associated levels of economic activity will further degrade many coastal habitats. Changes in the size, composition, and distribution of human populations affect coastal regions by changing land use and land cover. The NE of Brazil is sparsely populated inland but is densely populated at the coast. Main cities here include Recife and Fortaleza. The high concentration of people in coastal regions has produced many economic benefits, including improved transportation links, industrial and urban development, revenue from tourism, and food production. Tourism, fishing, and aquaculture are industries with major economic influences on coastal ecosystems. Help students locate the place where they live on the map. Check students’ drawings to make sure they understand why people live near coasts. }. The problem is particularly acute in developing countries. For example, Monaco, a principality located on France’s Mediterranean coast, is 2.02 square kilometers in size and has around 26,000 people per square kilometer. All three cities are densely populated and, while the nature's way of getting rid of pollution is through rains and long-lasting strong winds, the cities receive neither of the two. It is worked out by simply dividing the population by the area of the Federative Units.In 2014, Brazil had an overall population density of 24.66 inhabitants per square kilometer. Students should recognize that many more people live near the coasts than inland, although the Great Lakes and a few places in the interior, such as Atlanta, Georgia, are densely populated. They tend to fish close to the shore and use the catch to feed their families, whereas men typically engage in large-scale commercial fishing offshore or in major inland water bodies.28 Operating on a smaller scale, women who fish earn only 40 percent of what men earn for fishing in El Salvador.

Other articles where Coastal Plains is discussed: Texas: Relief: …the fertile and densely populated Coastal Plains in the southeast to the high plains and mountains in the west and northwest. Today, approximately 3 billion people — about half of the world’s population — live within 200 kilometers of a coastline. All Rights Reserved. As a result, the use of modern family planning methods among couples of reproductive age increased by 7 percent in less than two years, and communities decided to increase the size of protected marine areas from 12 to 203 hectares. The project used a three-stage approach to identify and address population changes that affect fishing in the area. 7 Up to 50 percent of the population in northern Africa and Bangladesh lives in coastal areas; along the Nile Delta, the population density reaches 500 to 1,000 people per square kilometer. At 824,292 km 2 (318,261 sq mi), Namibia is the world's thirty-fourth largest country. NG MapMaker Interactive: Population Density—United States, How People Affect Ocean Animals and Plants, identify patterns of human settlement on a United States population distribution map, brainstorm and draw possible reasons so many people live near the coast, Tech Setup: 1 computer per classroom, Projector. Coastal areas with high population densities are those with the most shoreline degradation or alteration. Waiyaki Way Cassia House, Ground Floor Join our community of educators and receive the latest information on National Geographic's resources for you and your students. After Mongolia, Namibia is the second least densely populated country in … Email: PRBKenya@prb.org, © 2020 Population Reference Bureau. In geography we are learning about people and population so this is a website to take people through the topic of people and population!!! With one birth every 7 seconds, a death every 13 seconds, and a migrant entering the country every 31 seconds, the United States’ population is growing at a rate of one person every 11 seconds. Coastal zone management Some 37 per cent of the world's population lives within 100 km of the coast, at a population density twice the global average. With a population of 48,003 people per square mile, Macau, a special administrative region of China, is the most densely populated region on … Breaking the marine food chain reduces vital supplies of protein for about 1 billion people, most of whom live in developing countries.27, Yet restricting fishing rights and access to coastal waters in order to project marine fauna may harm vulnerable groups of people. :) Display for students the United States on the NG Education interactive map, with the population density layer selected. Evidence links long-term, low-level exposure to certain POPs with reproductive, immunological, neurological, and other problems in marine organisms and humans.25 In Mozambique, for example, more than 100 factories in and around the capital city of Maputo do not have waste treatment plants; toxic wastes, poisons, nondegradable substances, and organic matter are drained into coastal waters.26 These toxins can kill or contaminate marine life; people who eat seafood from polluted areas or who swim in contaminated waters are vulnerable to gastric and other infections. Coastal regions, areas that are home to a large and growing proportion of the world’s population, are undergoing environmental decline. Photograph by Indumathi Govindasamy, My Shot.
