Maintaining a healthy coastal habitat is critical because most of the world’s fish produce their young inshore and feed on organisms in coastal waters. Regular collection of reliable data to measure the success of management initiatives. Have students locate where they live. Kenya, Liberia, the Philippines, and Puerto Rico, have lost over 70 percent of their mangroves.14. 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. Point out the East Coast and West Coast. 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. In a growing number of countries, coastal zone managers are adopting integrated, multidisciplinary approaches to resource management that incorporate the perspectives of all stakeholders, including governments, the private sector, nongovernmental organizations (NGOs), and individuals. Damming rivers can also have negative environmental effects, such as soil erosion and destruction of ecosystems that support various fish and marine mammals.

But the combined effects of booming population growth and economic and technological development are threatening the ecosystems that provide these economic benefits. Coastal regions also provide critical inputs for industry, including water and space for shipping and ports; opportunities for recreational activities such as fishing and diving; and other raw materials, including salt and sand. Without coastal defence mechanisms these would already be flooded today. However, along the coast, population densities are driven up by a large number of coastal … Coastal regions, areas that are home to a large and growing proportion of the world’s population, are undergoing environmental decline. 3362 days since Next Geography Class!!! Integrating Population, Health, and Environment Interventions in the Philippines: The People and Environment Coexistence Development Project. 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. These fishermen sometimes unknowingly exacerbate a problem created by tankers and ocean liners. After Mongolia, Namibia is the second least densely populated country in … Coastal resource managers and policymakers need to integrate health, population, gender, and nutrition considerations into ICM by determining the characteristics of beneficiaries and stakeholders, NGO capacity, and opportunities in specific areas. Reasons for densely and sparsely populated areas. Bénitez et al., “A Platform for Action for the Sustainable Management of Mangroves in the Gulf of Fonseca.”. Changes in the size, composition, and distribution of human populations affect coastal regions by changing land use and land cover. 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. 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. 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. 3. 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. Then explain to students how they can tell where many people live and where few people live. The reasons for environmental decline are complex, but population factors play a significant role. Email: PRBKenya@prb.org, © 2020 Population Reference Bureau. It can be used as a statistic to show how many people live in that specific area. the population distribution throughout the uk. Area: … In some areas, heavy use of fisheries has reduced endemic coastal fish stocks to 10 percent to 30 percent of the supply that existed 30 years ago.4 Half of the world’s wetlands disappeared in the 20th century, as did 50 percent of all mangroves, and nearly 60 percent of the world’s coral reefs are seriously degraded — in some cases beyond recovery — or threatened by development and other human activities.5 Pollution from industry, agriculture, and urban areas is degrading the quality of much of the world’s fresh water. Population Pyramids. More than 600 million people (around 10 per cent of the world’s population) live in coastal areas that are less than 10 meters above sea level. United Nations Development Programme (UNDP) et al.. United Nations Food and Agriculture Organization (FAO), Sara Curran et al., “Interactions Between Coastal and Marine Ecosystems and Human Population Systems: Perspectives on How Consumption Mediates This Interaction,”, United Nations System-Wide Earthwatch, “Oceans and Coastal Areas,” accessed online at http://earthwatch.unep.net/oceans/. 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. But tourism can also have harmful effects (see Box 1). Washington, DC 20009 At 824,292 km 2 (318,261 sq mi), Namibia is the world's thirty-fourth largest country. Population density is a ratio of the average number of inhabitants per square kilometre. Hence,many farmers prefer to settle here, people also settle here as it is the bestlandformto settle on and it has the most facilities like transportation, communication etc. Finally, people from local communities worked with PESCO-DEV to construct three-dimensional maps of their areas to highlight current land-use patterns and environmental resources. Manuel Benítez et al., “A Platform for Action for the Sustainable Management of Mangroves in the Gulf of Fonseca” (November 2000), accessed online at www.unesco.org/csi/wise/fonseca1.htm, on Aug. 14, 2003. R. Layng, “Strengthening Formative Environmental Research Through the Inclusion of Population Variables,”. A few cities actually top the chart of the most crowded urban areas in the US and the reasons for this demographic phenomenon are multiple. ICM projects developed out of separate single-sector programs, such as those introducing ecologically sound fishing practices and improving the quality and availability of couples counseling on family planning, and later evolved into integrated programs in which project staff worked with local communities and external experts to coordinate integrated population, health, and environment programs (see Box 2). Achieving a balance between top-down legislative authorities and bottom-up community involvement requires understanding issues and maintaining strong links with stakeholders in the area.

About 90% of the earth’s people live on only 10% of the land. Key Areas for Heavy Population Density. 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. The Northern Plains of India are densely populated due to the fine alluvium deposits which makes the plain very fertile. The reef is also threatened by inadequate treatment of sewage in the surrounding area. Population Reference Bureau The program focuses on understanding the structure and function of mangroves, seagrasses, and coral reefs, the primary coastal ecosystems in the Caribbean. If needed, have students explain what their drawings show. 4. Show students the NG Education interactive map. Coastal areas often offer good, arable land and the best land for easy transportation.

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. Tourism, fishing, and aquaculture are industries with major economic influences on coastal ecosystems. 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. 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. This policy brief looks at how population growth, urbanization, and other factors affect coastal resources; how environmental degradation influences people’s lives; and how policymakers can integrate population and resource management issues.
