What is Climate Vulnerability?
Historical Background
The concept of climate vulnerability gained prominence in the late 20th century as scientific evidence of climate change accumulated. Early assessments focused on the physical impacts of climate change, such as sea-level rise and temperature increases. The Intergovernmental Panel on Climate Change (IPCC) played a crucial role in defining and assessing climate vulnerability.
The IPCC's reports highlighted the uneven distribution of climate impacts, with developing countries and vulnerable populations disproportionately affected. Over time, the understanding of climate vulnerability evolved to include social, economic, and political factors. The focus shifted from simply identifying vulnerable areas to understanding the underlying drivers of vulnerability and building adaptive capacity.
International agreements, such as the Paris Agreement, recognize the importance of addressing climate vulnerability and promoting adaptation measures. The concept continues to evolve as new research and data become available.
Key Points
12 points- 1.
Climate vulnerability is determined by three key factors: exposure (the degree to which a system is subjected to climate change), sensitivity (the degree to which a system is affected by climate change), and adaptive capacity (the ability of a system to adjust to climate change).
- 2.
Exposure can be measured by assessing changes in temperature, precipitation, sea level, and extreme weather events in a specific region.
- 3.
Sensitivity depends on the characteristics of the system, such as the reliance of a community on agriculture or the presence of vulnerable ecosystems.
- 4.
Adaptive capacity is influenced by factors such as access to resources, technology, education, and governance.
- 5.
Different sectors, such as agriculture, water resources, health, and infrastructure, have varying levels of climate vulnerability.

Climate vulnerability is highly relevant for the UPSC exam, particularly for GS Paper III (Environment & Ecology) and GS Paper I (Geography). It is frequently asked in both prelims and mains. Questions can focus on the factors influencing vulnerability, the impacts of climate change on vulnerable populations, and strategies for reducing vulnerability.
In prelims, expect factual questions about key concepts and international agreements. In mains, expect analytical questions requiring you to discuss the challenges and opportunities related to climate vulnerability in India. Essay topics related to climate change often require an understanding of vulnerability.
Recent years have seen an increase in questions related to climate change adaptation and resilience, which are directly linked to climate vulnerability. When answering questions, provide specific examples and case studies to illustrate your points.
Frequently Asked Questions
61. What is climate vulnerability, and what are its key determining factors as relevant for the UPSC exam?
Climate vulnerability refers to the degree to which a system is susceptible to, and unable to cope with, the adverse effects of climate change, including climate variability and extreme weather events. As per the concept, it is determined by three key factors: * Exposure: The degree to which a system is subjected to climate change. * Sensitivity: The degree to which a system is affected by climate change. * Adaptive Capacity: The ability of a system to adjust to climate change.
- •Exposure refers to the extent to which a system experiences climate-related stressors.
- •Sensitivity is the degree to which a system is affected by changes in climate conditions.
- •Adaptive capacity refers to the ability of a system to adjust to climate change impacts and moderate potential damages.
Exam Tip
Remember the acronym ESA (Exposure, Sensitivity, Adaptive Capacity) to easily recall the three key factors determining climate vulnerability.
