Worked Solution & Example Answer:With reference to a coastal environment at a local scale, assess the predicted impact of climate change upon the landscape - AQA - A-Level Geography - Question 3 - 2020 - Paper 1
Step 1
Introduction to Coastal Environments and Climate Change
Answer
Coastal environments are dynamic ecosystems influenced by various factors, including climate change. Understanding how climate change affects coastal landscapes is crucial for assessing future impacts. In this context, we will refer specifically to Great Yarmouth in the UK as a case study.
Step 2
Impact of Rising Sea Levels
Answer
One of the primary impacts of climate change on coastal areas is the rise in sea levels. In Great Yarmouth, rising sea levels can lead to increased flooding, particularly in low-lying areas. This poses a threat to infrastructure and habitats, increasing the risk of erosion along the coastline.
Step 3
Increased Frequency of Extreme Weather Events
Answer
Climate change is predicted to increase the frequency and intensity of extreme weather events, such as storms. Great Yarmouth is prone to coastal erosion, and stronger storms can significantly expedite this process. Homes and businesses near the coastline are at a higher risk, leading to economic and social implications.
Step 4
Changing Ecosystems and Biodiversity
Answer
The shifting climate will also impact local ecosystems. Changes in temperature and salinity can affect marine life, disrupting the food chain and leading to shifts in species populations. For example, traditional fish species may decline, impacting local fisheries and economies.
Step 5
Human and Economic Impacts
Answer
The repercussions of these environmental changes extend to human communities. Increased flooding can lead to property damage and displacement of residents. Moreover, the economic impact can be severe, with potential losses in tourism and local businesses relying on a stable coastal environment.
Step 6
Mitigation and Adaptation Strategies
Answer
In response to these threats, Great Yarmouth is exploring various coastal management strategies. Measures include strengthening sea defences and developing sustainable practices to mitigate the impact of climate change. However, adapting to these changes requires substantial investment and community involvement.
Step 7
Conclusion and Evaluation
Answer
In summary, climate change poses significant threats to coastal environments like Great Yarmouth, impacting landscapes, ecosystems, and human communities. While the predicted impacts are severe, effective mitigation and adaptation strategies can help manage these challenges, ultimately influencing the long-term sustainability of the coastal landscape.
