Worked Solution & Example Answer:‘Climate change is on course to radically alter the role of water in deserts and their margins, affecting both human populations and the physical landscape.’ To what extent do you agree with this view? - AQA - A-Level Geography - Question 2 - 2018 - Paper 1
Step 1
Introduction
Answer
In examining the statement regarding the impact of climate change on deserts, it is vital to consider both the ecological and human dimensions. Climate change poses significant challenges, including increased temperatures and altered precipitation patterns that are likely to impact water availability in arid regions.
Step 2
Impact on Human Populations
Answer
The implications for human populations in deserts are profound. Higher temperatures and reduced water availability may exacerbate existing vulnerabilities, leading to food insecurity and displacement. Communities relying on agriculture will face challenges as the balance of water resources shifts, further endangering livelihoods.
Step 3
Impact on Physical Landscape
Answer
On the physical landscape front, climate change is expected to transform ecosystems. Alterations in water availability can lead to desertification—a process defined as land degradation due to various factors including climatic changes. Expanded dry areas may force natural vegetation to adapt or perish, encouraging erosion and altering habitat dynamics.
Step 4
Case Studies and Evidence
Answer
Evidence from regions such as the Sahel demonstrates the direct correlation between rising temperatures, reduced rainfall, and the challenges these pose to both ecology and human habitation. Studies indicate that ongoing shifts will lead to water scarcity, subsequently affecting agriculture and exacerbating socio-economic issues.
Step 5
Conclusion
Answer
In conclusion, I strongly agree with the view that climate change will profoundly alter the role of water in deserts. The consequences will extend beyond environmental degradation to include substantial impacts on human populations, necessitating urgent adaptive strategies and international cooperation.
