Climate Vulnerability

What is Climate Vulnerability?

Climate vulnerability refers to the degree to which a system is susceptible to, and unable to cope with, the adverse effects of climate change. This includes climate variability and extreme weather events. It is a function of the character, magnitude, and rate of climate change and variation to which a system is exposed. It also depends on its sensitivity and adaptive capacity. Vulnerability is high when exposure and sensitivity are high, and adaptive capacity is low. For example, coastal communities are highly vulnerable due to rising sea levels. Farmers relying on rain-fed agriculture are vulnerable to droughts. Understanding climate vulnerability is crucial for developing effective adaptation strategies and building resilience. It helps prioritize resources and actions to protect the most vulnerable populations and ecosystems. It is assessed using various indicators and models.

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

1. 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.

2. How does climate vulnerability manifest differently across various sectors, such as agriculture, water resources, and health?

Different sectors exhibit varying levels of climate vulnerability due to their unique characteristics and dependencies. As per the concept, different sectors, such as agriculture, water resources, health, and infrastructure, have varying levels of climate vulnerability. For example: * Agriculture: Highly vulnerable due to dependence on rainfall patterns and temperature, affecting crop yields and food security. * Water Resources: Vulnerable due to changes in precipitation patterns, leading to droughts or floods, impacting water availability and quality. * Health: Vulnerable due to increased frequency of heatwaves, spread of vector-borne diseases, and impacts on air quality.

  • Agriculture's vulnerability is linked to its direct reliance on climate-sensitive resources.
  • Water resources are vulnerable due to the hydrological cycle being directly impacted by climate change.
  • Health sector vulnerability is often exacerbated by socio-economic factors.

Exam Tip

When answering questions related to sectoral impacts, always link the impact back to the core drivers of climate vulnerability: exposure, sensitivity, and adaptive capacity.
