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
Knowledge of the Inter-relationship
Answer
The inter-relationship between climate, soils, and vegetation in arid regions is complex and crucial for understanding ecosystem dynamics. In these environments, the climate plays a significant role, with low precipitation levels and extreme temperatures impacting both soil properties and vegetation types. Vegetation, in turn, influences soil stability and moisture retention, which are vital for sustaining desert ecosystems.
Step 2
Human Activity's Impact
Answer
Human activity, particularly through urbanization and agricultural practices, increasingly disrupts these delicate systems. For example, land conversion for agriculture can lead to soil degradation and loss of native vegetation. Over-extraction of water resources affects both soil moisture levels and the biodiversity within these arid environments. The effects of such activities are often irreversible, leading to desertification and habitat loss.
Step 3
Evidence Supporting the View
Answer
Research indicates that as human populations grow and industrial activities expand, the push for land and resource use intensifies. This encroachment leads to significant ecological shifts. Techniques like clear-cutting for farmland not only diminish vegetative cover but also change local microclimates, exacerbating soil erosion and further limiting vegetation growth. Therefore, I strongly agree that the inter-relationships are indeed becoming more fragile.
Step 4
Alternative Perspectives
Answer
It's essential to acknowledge that there are methods, such as sustainable agriculture and reforestation, aimed at mitigating these negative effects. Strategies like the construction of systems like the Green Wall can help balance human interests and ecological preservation, highlighting the potential for a sustainable coexistence.
Step 5
Conclusion
Answer
In conclusion, while human activity undoubtedly disrupts the fragile inter-relationships between climate, soils, and vegetation in arid regions, there remains hope through sustainable practices that could restore balance. Continued awareness and proactive measures are necessary to protect these ecosystems for future generations.
