The paper provides an insight into the chronological extinction of the Indo-Malayan mangroves along the South and Southeast Asian coast and categorizes several area-specific anthropogenic and climatic factors that triggered the annihilation of 1.9 million ha of diverse mangroves. In the VNRs, mangroves are likely to be implicit within SDG targets that vaguely describe marine and coastal ecosystems (Target 14.2) or coastal and marine areas (Target 14.5). Describe and explain how coral reefs offer opportunities for human activity. For mangroves, sea level rise is the biggest climate-related threat, with some tree species unable to tolerate the influx of saltwater or escape the surging tides. A sizable proportion of research also addressed questions about fish health (n=58), trophic ecology (n=38) and population biology (n=25). An important natural ecosystem, it is constantly threatened by human actions or conditions that are speed up by human activities. Visualizing the Human Impact on the Earth’s Surface. Another characteristic of polluted coasts is the presence of oil spills and disruption of the balance of coastal ecosystems. The role of mangroves in coastal risk reduction 13 2.1 Mangroves reduce wave damage 14 2.2 Mangroves reduce damage from large storms 16 2.3 Mangroves can help to reduce tsunami damage 18 2.4 Mangroves reduce erosion and bind soils together 20 2.5 Mangroves … With a population of over 41.7 million people, Bangladesh is a populous country, well known for experiencing annual floods that have impacted on the country in various ways. Mangroves can also contribute to regulating various geochemical cycles, and Mandal et al. Humans harvest fish, crabs, shellfish, reptile skins, and honey at subsistence and artisanal levels from most of the world's mangroves ( Nurkin 1994 ). You should be able to give several named example. Below are the most common harm to the reef by humans. Set against this is a growing realisation of the social and economic value of mangroves and a remarkable array of restoration efforts in many countries around the world.” Climate change will exacerbate existing pressures, the authors add. Bangladesh is located in Southern Asia in between Burma and India, bordering the Bay of Bengal. Mangroves are utilized in many parts of the world as a renewable resource. Harvested for durable, water-resistant wood, mangroves have been used in building houses, boats, pilings, and furniture. Mangroves are ecologically important and extensive in the Neotropics, but they are visibly threatened by selective logging and conversion to pastures in the Southern Caribbean. 2000). STB-3.E.1. As such, these ecosystems have well-developed strategies Furthermore, information on the impacts on wetland biogeochemical processes and the resulting ecosystem services together with their ultimate link to human well-being is absent. Some SDG targets and their indicators may indeed be positive for mangroves and others may not. of how human activity can result in positive impacts on a coastal landscape. Wetlands are constantly adjusting to disturbances occurring within them and within the surrounding landscape. Human Activity: Human activities which may lead to losses of coastal wetlands include urban and rural development, agriculture, and silviculture. The above conditions are generally caused by: Over-harvesting of wood from mangrove forests. Coastal wetlands, including mangrove forests, absorb a significant amount of greenhouse gas emissions. Impacts and causes of mangrove degradation/loss Degraded and loss of mangroves has caused coastal abrasion, sea water intrusion, flood, loss of settlements due to storm, loss of natural fishing areas, and opportunities to mitigate greenhouse gas emissions. Mangroves provide ideal breeding grounds for much of the world's fish, shrimp, crabs, and other shellfish. Most recently, mangroves have become recognized for their ability to regulate global climate through the sequestration and storage of ‘blue carbon’. Many fish species, such as barracuda, tarpon, and snook, find shelter among the mangrove roots as juveniles, head out to forage in the seagrass beds as they grow, and move into the open ocean as adults. 2017). Brings increase publicity and prestige for wetlands. Types of Wetland Impacts Human Impacts Wetlands provide a variety of ecological services, including water purification, flood protection, water filtration, and habitat STB-4.C.3. An unreported number of Rhizophora mangle L. … We first describe the various climate change impacts expected to affect the mangrove ecosystem, particularly sea level rise, storminess, precipitation, and temperature. Present an opportunity for a country to be heard in the principal intergovernmental forum on conservation and wise use of wetlands. The Great Barrier Reef is considered as a World Heritage Area located at the coast of Queensland. HUMAN IMPACTS ON MANGROVES Activity 3-F: Oil Spill Clean-up Summary Students will learn about the impact that oil spills, large or small, have on our waterways and wetlands. Not only sea pollution or ocean pollution, coastal pollution also has occurred on almost all beaches that become tourist attractions.Among the characteristics of coastal pollution that we can see immediately is the amount of garbage scattered along the coast. Describe and explain how the impacts of human activities on coral reefs can be minimised. Excessive harvesting – including kina, snails, bivalves, crabs and flounder used for either eating or bait. Here are the 20 Human Impacts on the Great Barrier Reef. You should be able to give several named example. ... many do not realise the harmful effects this activity has on these animals. STB-3.E. Fewer studies have examined the impacts of human activities on fish populations (n=21), the benefits of conservation for fish (n=15) or the effects of fish on ecological functions (n=12). Coastal mangroves and wetlands, which protect vulnerable coastlines from storm surge and flooding, are threatened by sea level rise. 3 4-5 marks Demonstrates accurate knowledge and understanding of human activity in a coastal landscape.
