Internationally the UK continues to push for greater protection of marine habitats on the world stage with 20 countries joining the UK-led Global Ocean Alliance, which aims to secure protection for at least 30% of the worlds oceans by 2030. dredging of sands and gravels. [6]. positive impacts on beaches and tourism generated by deployment of groynes leading to increased erosion and negative impacts further down the coastline. For the most part because the coast is a very dynamic system and changes can occur rapidly, people make the effort to control the nature and magnitude of these changes. Have students watch three videos about human activities that threaten the world ocean. [8], AO1 the extent to which there has been a changing focus of coastal erosion as sediment is trapped by groynes - orientation of coast There have been many disastrous chemical spills at sea and from industry on land, affecting animals immediately via ingestion, or long term, in changes to reproduction cycles and other biological processes. Physical Human activities shape the structure of landscapes in different ways and hence modify animal communities depending on the type and intensity of these activities. isostatic recovery takes place (slowly/over a long period of time) Positive impacts could include the management and conservation of environmentally sensitive areas, the protection of areas of coastline from erosion as part of a shoreline management plan (SMP), where there has been an improvement of the coast as an amenity or where there is a perceived improvement in the aesthetic character of the coastline the movement of sediment may keep harbours clear and accessible When water and wind batter the shoreline sediments are carried out to sea and deposited on the sea floor or at other points along the coastline. (a) (i) Calculate the values of the highlighted cells, A, B and C in Figure 2. Encyclopedia of Coastal Science pp 983991Cite as, Part of the Encyclopedia of Earth Sciences Series book series (EESS). [2], linear clefts in a cliff / narrow inlet, 4. Knowledge and understanding of the positive impacts of these processes on human activity e.g. Candidates could also consider other factors that affect coastal processes and landforms e.g. Floods Cause Sedimentation and Erosion Floodwater can also alter the landscape, for instance, by eroding riverbanks and causing them to collapse. 3.6 billion People live near or around a coast. The extent to which the role of sub aerial processes can vary over time and in different locations The Human Impact on Coastal Landscape. So the beach bums and the sea life may continue to enjoy one of the most beloved landscape for generations to, A big problem in Cape Cod is beach erosion. 3. Assessment of the level of positive impacts Sands and gravels eroded from the shores of coastal bays maintain the beach as a natural barrier between the open water and coastal wetlands. Knowledge and understanding of the processes operating over a time scale of millennia - isostatic and eustatic changes Lynch-Blosse, M.A., and Davis, R.A., 1977. Relevant responses may include: Overall, there are many ways whereby human activities have caused problems for a broad spectrum of coastal environments. The human cost of flooding can be large, but events like this have a big impact on the natural world too, and the effects are not always negative. The specification identifies the following landforms as depositional - beaches, spits, bars, tombolos and cuspate forelands. Your answer should include: Swimming / Living / Sunbathing. Groynes have been eroded away Ease of construction Lack of groundwater - some areas may be drier and so the sediment dries out and easier to erode by wind or development of example, 20. The drift line is formed by the dead seaweed and other aquatic plants. Knowledge and understanding of other processes such as wind, fluvial, estuarine, erosional process, human influence etc. melting of glaciers Around the world, many projects are now seeking to restore marine habitats, such as mangrove and seagrass. Examine the strengths and weaknesses of one strategy used to manage the impacts of human activity on coastal landscape systems. National Research Council, 1995. Damage to housing shown on photo -Allotments, (a) Use Figure 2 to describe the pattern of wave energy. Human activities add another layer of complexity to the natural processes of coastal lands and materials. Assess the relative importance of longshore drift in the formation of one or more landforms of coastal deposition. The content will depend upon the management strategy chosen but there are a number of threads that are worthy of credit: A conclusion may be drawn in the context of the strategy chosen but a conclusion is not necessary in order to reach the top of Band 3. A study by Halpern et al. least in Bridgend, 20. Human Write the correct word in the space next to each definition. AO1 content encompasses knowledge and understanding of how erosional, and other valid, processes produce landforms. 9.4 Coastal landscapes and processes (The Earth's crust is modified by . In England, 271 million recreational visits are made to coastal environments annually and more than 22 million people live within 5 miles of the coast. Arrowed explanations will assist the candidate to reach Band 3. . We can all be conservationists, and many people are doing their bit at home to protect the Ocean. Reading exact data figures, easy? the changing role of wind with distance inland Knowledge and understanding of processes of coastal erosion Material from beach can be transported to other beaches, 17. Loss of farm land in the southern section of the photograph Through the implementation of the 25 Year Environment Plan, the UK continues to consider the need for further domestic protection, and is putting in place new management measures for Marine Protected Areas, including seeking new powers through the Fisheries Bill, which is currently before Parliament. AO2 Identification of individual groups? Addresses the impacts of humans on landscapes and landscapes on humans, including themes such as resource management, degradation, sustainability, and meaning. The primary dune's main function is to absorb the force of the ocean and protect the great south bay and the island's main coast. Human activity along the coast has both positive and negative impacts on the natural environments. (a) Use Figure 1 to describe two distinctive landforms of this coastal landscape. Many time a maritime forests will form on secondary dunes. the impact on the aesthetics of the coast This has been successful in reducing the amount of sand that is drawn out to sea. [2]. Spartina alterniflora is considered an invasive species that has affected the biogeochemical circle of carbon in coastal wetlands around the world. Find out ways you can #thinkocean. homelessness Washington, DC: National Academy Press. 293303. [15], AO1 (2019) suggests that climate change is currently by far the most important stressor for ocean and coastal ecosystems.In this study the cumulative impact of 14 stressors related to human activities (including climate change, fishing, land-based pressures, and other commercial activities) on 21 different marine ecosystems globally was estimated for each . Location 1 1960 - Location 2 1969 advancement AO2 Candidates should demonstrate application of knowledge and understanding through an examination of the extent to which one coastal management strategy has been successful. Humans also impact the land around or near the coast. The sand is then pulled out to sea where it forms a sand bar. Answers could address the following but credit other valid responses: Usefulness: reference to conditions of formation - depth, light, currents (b) Examine the role of marine erosional processes in the formation of one or more landforms of coastal erosion. Location 1 has most decrease/erosion and greatest range Another impact on the coast is pollution. e.g. Impact of human activity on vegetation across a sand dune complex, Interrelationships between vegetation, soils & Shows any visual changes over time of the environment Despite the negativity surrounding the current state of our Ocean, the good news is that its not too late to turn things around. The geological structure incorporates bedding planes, dip, folding and faulting and can add distinctive features to these landforms. Field Sketches: knowledge and understanding of how lithological factors influence the development of the selected landform(s) - this may include reference to mineral composition, solubility and hardness Credit any other valid points. You can change your cookie settings at any time. knowledge and understanding of the operation of the management strategy the role of biotic factors Understanding of the link between processes and the formation of the selected erosional landform water locked into glaciers Research shows that underwater noise from construction, shipping and naval vessels significantly impacts the natural behaviour of cetaceans and many other marine species.
