CDRA 2: Scoping the Potential Impacts of Disasters and Climate Change
Summary
TLDRThis instructional video series guides local government units (LGUs) in Central Luzon through the process of incorporating climate change impacts into their comprehensive development plans. The video outlines how to identify and assess climate stimuli such as sea level rise, temperature, and extreme weather events. It explains how to develop impact chain diagrams that trace the effects of climate change on various sectors and communities, offering a comprehensive approach to understanding these challenges. The video emphasizes collaboration with stakeholders and utilizing data to identify vulnerabilities across ecosystems and exposure elements.
Takeaways
- 😀 The Department of the Interior and Local Government Central Luzon presents instructional videos on formulating and updating LGU Comprehensive Development Plans.
- 😀 The main outputs of the step include a summary of potential climate change impacts and exposed units, as well as impact chain diagrams.
- 😀 Four major climate variables (sea level rise, temperature, rainfall, and extreme daily events) trigger or affect natural hazards in a locality.
- 😀 Stakeholder workshops can group participants based on ecosystems or exposure elements to better understand climate change impacts.
- 😀 Climate change impact chain diagrams map the effects of climate stimuli, identifying primary, secondary, and tertiary impacts on communities and sectors.
- 😀 Examples of secondary impacts include coastal flooding, disease spread, loss of crops, and water pollution caused by extreme weather events.
- 😀 Drought leads to secondary impacts like marine heat waves, water scarcity, and higher prices for agricultural commodities.
- 😀 The impact chain diagram method can integrate multiple climate stimuli to show how different factors interrelate and affect various sectors.
- 😀 After creating the impact chain diagrams, a summary matrix can be used to show how each climate variable affects exposure elements like population and infrastructure.
- 😀 The summary matrix helps identify affected areas and sectors, such as barangays, critical facilities, and lifeline utilities.
Q & A
What are the two major outputs of Step 2 in the climate change impact assessment process?
-The two major outputs are: 1) A summary of potential climate change impacts and exposed units, and 2) Impact chain diagrams.
What are the four major climate variables that can trigger natural hazards?
-The four major climate variables are: Sea level rise, temperature, rainfall, and extreme daily events (such as hot days, dry days, droughts, and extreme heavy rainfall).
How can stakeholders be grouped during workshops to identify climate change impacts?
-Stakeholders can be grouped by ecosystems (e.g., coastal, urban, riverine, agricultural, upland forests), by exposure elements (e.g., population, urban areas, natural resources, critical facilities), or by climate variables present in the locality.
What is the basic method for creating a climate change impact chain diagram?
-The method involves identifying the climate stimulus, determining the primary impact, and then identifying the secondary and tertiary impacts, tracing the chronological effects of a particular climate variable on the community.
What example is given for the impacts of increased extreme daily rainfall?
-Increased extreme daily rainfall can cause primary impacts like frequent flooding, secondary impacts like coastal flooding, shoreline degradation, and disease spread, and tertiary impacts like loss of crops, livelihood, and pollution of water resources.
What are some secondary impacts of drought as described in the script?
-Secondary impacts of drought include ocean warming, marine heat waves affecting aquatic species, increased malnutrition and disease, water scarcity for agriculture, and reduced forest productivity due to insect pests and disease.
What is the advantage of combining multiple climate stimuli in an impact chain diagram?
-The advantage is that it allows the assessment of how different climate variables interrelate and affect multiple sectors in one diagram, providing a more comprehensive understanding of the impacts.
How are the findings from the climate change impact chain diagrams summarized?
-The findings are summarized in a matrix, which includes the effect of each climate variable on exposure elements like population, production areas, critical facilities, and infrastructure, along with the number of barangays (villages) affected.
Why is it important to group workshop participants by ecosystems or exposure elements?
-It is important because grouping by ecosystems or exposure elements allows for a more accurate assessment of the specific climate change impacts on different parts of the locality, considering their unique characteristics.
What potential impacts are associated with extreme rainfall events in coastal areas?
-Extreme rainfall can lead to coastal flooding, erosion, the degradation of shoreline features, disruption of businesses and activities along the beach, and increased morbidity from diseases, particularly among children.
