As many cities and counties hold conversations on how to build sustainability and resilience within their communities, it is important to understand how to start that journey. It all starts with a climate change vulnerability assessment (CVA). This assessment evaluates the susceptibility of systems, communities, or assets to the adverse impacts of climate change.
A comprehensive CVA reveals your exposure and sensitivity to climate hazards, and the capacity to adapt. which in turn informs the development of targeted adaptation strategies and plans to build resilience. It is the basis of most Sustainability Action Plans that you will execute as a City Sustainability Manager so it is important to get it right.
CVAs are vital for developing targeted adaptation strategies and plans. As a City Sustainability Official, ensuring the accuracy of this assessment is essential, as it forms the foundation of most Sustainability Action Plans.
Here are key steps to consider when undertaking your CVA:
Step 1: Define Objectives and Scope
Articulate the goals of the vulnerability assessment - what questions are you trying to answer? Common objectives include identifying your top climate risks, most vulnerable populations and assets, and priority areas for adaptation.
Determine the scope in terms of geography (citywide/countywide vs specific neighborhoods), timeframes (near-term, mid-century, end-of-century), climate hazards, and sectors/systems to be assessed.
Identify and engage key stakeholders across government, infrastructure operators, businesses, community organizations, academia, etc. Their input and support will validate and strengthen your study.
Step 2: Gather Data on Climate Hazards and Impacts
Work with local institutions like universities, government agencies, and climate scientists to obtain relevant climate projections. Focus on the hazards most relevant to your region such as sea level rise, extreme heat, drought, wildfires, and extreme precipitation.
Collect data on historical climate trends and impacts to understand existing vulnerabilities. Sources include local weather stations, insurance claims, disaster declarations, and government agencies like FEMA, CDC, NOAH, etc.
Use mapping tools to visualize spatial data on hazards, land use, demographics, natural resources, critical infrastructure, etc. Many free tools exist.
Step 3: Assess Vulnerability
Evaluate your city or county’s exposure and sensitivity to climate impacts, and its capacity to adapt. Vulnerability will vary from place to place, so focus on local conditions.
Identify areas exposed to climate hazards by overlaying spatial hazard data (e.g. flood maps) with the locations of people, assets, and ecosystems that could be adversely affected.
Evaluate sensitivity i.e. the degree to which exposed systems could be impacted. Consider both physical sensitivity (e.g. a road's susceptibility to being damaged by flooding) and social vulnerability (e.g. an elderly population's vulnerability to extreme heat)
Assess the adaptive capacity - the ability to adjust to potential impacts. Look at factors like the community's access to resources, social cohesion, and overall resilience.
Engage stakeholders to get local, on-the-ground perspectives on vulnerabilities. Supplement your data analysis with surveys, interviews, and workshops with community members.
Step 4: Assess Risk
Risk is the potential for negative consequences. This is a function of the probability of a climate impact occurring, and the magnitude or severity of the consequences if it does occur.
Characterize risk by level (low, medium, high, etc.) based on the probability and severity of potential impacts on people, property, infrastructure, and natural systems.
Prioritize adaptation planning based on the risk for injury, financial losses, disruption of critical services, and impacts on vulnerable populations.
Step 5: Identify Adaptation Options
For each major risk identified, brainstorm potential adaptation strategies to reduce vulnerability. Consider policy changes, infrastructure investments, nature-based solutions, outreach programs, etc.
Evaluate and prioritize options based on criteria like effectiveness, cost, feasibility, co-benefits, and equity considerations. Stakeholder and community input is key.
Step 6: Develop Implementation Plans
Incorporate priority adaptation strategies into your plans, policies, and budgets. Assign clear roles and responsibilities.
Establish a framework to monitor changing risks and evaluate the effectiveness of interventions over time. Course-correct as needed.
Communicate results to build public awareness and support for implementation.
6. Monitor, track and adjust
Track implementation progress and evaluate the effectiveness of adaptation actions.
Review and update the vulnerability assessment and adaptation plan regularly to reflect new information and priorities.
