Worked Solution & Example Answer:‘The fragile inter-relationship between climate, soils and vegetation in arid regions is becoming increasingly affected by human activity.’ How far do you agree with this view? - AQA - A-Level Geography - Question 2 - 2019 - Paper 1
Step 1
Introduction to the Fragile Inter-relationship
Answer
The inter-relationship between climate, soils, and vegetation in arid regions is critically delicate due to the harsh environmental conditions. Human activity, through urbanization, agriculture, and deforestation, has been increasingly disrupting these interactions, leading to degraded ecosystems. In this answer, I will evaluate the extent to which I agree with the statement regarding human influence on these fragile systems.
Step 2
Human Activity and Environmental Changes
Answer
Human activities significantly impact the environment by altering natural landscapes and ecosystems. For instance, the expansion of agricultural land into desert areas can result in soil degradation and loss of vegetation. This affects local climate patterns and water availability. The introduction of irrigation, while initially beneficial, can lead to salinization and further soil deterioration.
Step 3
Impacts of Climate Change
Answer
Climate change, exacerbated by human actions, has introduced unpredictable weather patterns, affecting arid environments adversely. Increased temperatures and altered rainfall patterns may lead to more extreme droughts, impacting the vegetation that has adapted to specific climatic conditions. These changes make the ecosystems more hostile and threaten the survival of endemic species, which are already vulnerable.
Step 4
Examples of Human Encroachment
Answer
Cases such as the degradation of desert regions due to urban expansion and mining demonstrate the rising impact of human activity. The removal of native vegetation for development projects not only disrupts the local climate but also leads to loss of biodiversity. Additionally, various desertification processes are accelerated by overgrazing and deforestation, intensifying soil erosion.
Step 5
Positive Human Interventions
Answer
However, it is also important to acknowledge positive human interventions aimed at preserving these ecosystems. Initiatives such as reforestation and sustainable land management practices can help mitigate some of the adverse effects of human activity. Implementing strategies like the Green Wall project can support the restoration of vegetation in desert margins, enhancing stability and productivity.
Step 6
Conclusion
Answer
In conclusion, I agree with the view that human activities are increasingly affecting the fragile inter-relationships between climate, soils, and vegetation in arid regions. While there are efforts to combat these challenges, the overall trend indicates a negative impact. Knowledge, understanding, and a commitment to sustainable practices are crucial for preserving these ecosystems in the face of ongoing human influence.
