CDRA 4: Conduct Climate Change Vulnerability Assessment

Summary

This instructional video series, presented by the Department of the Interior and Local Government of Central Luzon, guides local government units (LGUs) in conducting a Climate Change Vulnerability Assessment (CCVA). The video covers the process of assessing vulnerabilities to climate-related stimuli, focusing on the interplay between exposure, sensitivity, and adaptive capacity. Key components include creating exposure databases for various sectors such as population, urban areas, and natural resources, followed by evaluating impacts, adaptive capacity, and calculating vulnerability indexes. The final goal is to identify decision areas needing intervention and propose effective policy solutions to address climate change vulnerabilities.

Takeaways

• 😀 CCVA (Climate Change Vulnerability Assessment) helps assess a locality's vulnerabilities to climate-related impacts like extreme weather and climate variability.
• 😀 Vulnerability refers to how susceptible a system is to the adverse effects of climate change and its ability to cope with these effects.
• 😀 CCVA uses a qualitative approach, involving non-numerical data collection methods like interviews, focus group discussions, and surveys to assess vulnerability.
• 😀 The assessment process involves identifying exposure units, conducting sensitivity analysis, and evaluating adaptive capacity to calculate the vulnerability index.
• 😀 The vulnerability index is determined by combining the degree of impact of climate stimuli with the system's adaptive capacity.
• 😀 The Exposure Database includes information on population sensitivity, urban uses, natural resource-based production areas, critical point facilities, and lifeline utilities.
• 😀 Sensitivity factors for population assessment include construction materials, disability rates, early warning systems, and income levels.
• 😀 Adaptive capacity is evaluated based on factors such as access to financial assistance, willingness to adapt, and government support programs.
• 😀 Vulnerability assessment maps visualize the most exposed areas, highlighting sectors like urban zones or agricultural areas facing climate risks.
• 😀 Key steps in CCVA include organizing climate exposure data, scoring the degree of impact and adaptive capacity, and summarizing findings for decision-making.
• 😀 The final output is a vulnerability assessment summary matrix, identifying decision areas in need of intervention and recommending policy actions for climate resilience.

Q & A

What is the purpose of conducting a Climate Change Vulnerability Assessment (CCVA)?

The purpose of conducting a CCVA is to assess the vulnerabilities of a locality to climate-related stimuli, identifying how susceptible various sectors or systems are to the adverse effects of climate change, including climate variability and extremes.

What is the difference between qualitative and quantitative research in CCVA?

Qualitative research in CCVA involves collecting and analyzing non-numerical data to understand concepts, opinions, or experiences, such as people's perceptions of climate impacts. In contrast, quantitative research involves the collection and analysis of numerical data for statistical purposes.

What are the key components of the exposure database in CCVA?

The key components of the exposure database in CCVA include exposure, sensitivity, and adaptive capacity data. These components help assess the potential impact of climate change on various sectors like population, urban areas, natural resources, critical facilities, and lifeline utilities.

How is the sensitivity of the population assessed in CCVA?

The sensitivity of the population is assessed by evaluating factors such as wall construction materials, access to early warning systems, percentage of informal settlers, vulnerability due to income levels, and education levels. Data for this can often be obtained from the CBMS (Community-Based Monitoring System) and local government units.

What is the role of adaptive capacity in the vulnerability assessment?

Adaptive capacity refers to the ability of a system or population to cope with and adjust to climate change impacts. In the vulnerability assessment, adaptive capacity is evaluated based on factors like access to financial assistance, government support, and willingness to take mitigation measures, such as retrofitting buildings or relocating.

What type of data is used to assess the adaptive capacity of urban areas?

The adaptive capacity of urban areas is assessed by analyzing data on government regulations, insurance coverage, capacity for retrofitting or relocation, and availability of alternative sites for relocation. These factors help determine how well urban areas can withstand and adapt to climate impacts.

What are the challenges in gathering data for the urban exposure database?

A key challenge in gathering data for the urban exposure database is the lack of an inventory of buildings, especially for commercial, industrial, and private establishments. In the absence of such data, local officials, such as building officers or barangay personnel, can assist in providing estimates based on their knowledge.

How is the degree of impact of each exposure unit determined in the vulnerability assessment?

The degree of impact for each exposure unit is determined by assessing the potential consequences of climate stimuli, such as flooding or sea-level rise. Each exposure unit is scored based on its level of impact, with ratings of 'high,' 'moderate,' or 'low' depending on how severe the effects are on that area.

What are decision areas in the context of the CCVA, and how are they identified?

Decision areas refer to the priority areas in need of intervention due to their high vulnerability to climate change. These areas are identified based on the results of the vulnerability assessment, specifically by analyzing the exposure, sensitivity, and adaptive capacity of different sectors, and noting areas most prone to climate risks.

What are the steps to prepare a vulnerability assessment map?

To prepare a vulnerability assessment map, the first step is to organize climate exposure maps and tables that include data on the areas exposed to various climate stimuli. Next, the degree of impact and adaptive capacity are assessed for each unit, and the vulnerability index is calculated. The resulting map visualizes areas most at risk from climate change hazards.
