How to Leverage Case Studies


An infographic for How to Leverage Diverse Case Studies. Infographic text is below.

Use

  • Co-benefit research approach.

How?

  • Expand research scope to include case studies with different theme/climate adaptation goals.

Why?

  • Transferable Strategies. Case studies in unrelated sectors often reveal adaptable processes.
  • Systemic Risk Reduction. Rarely an isolated issue-usually interacts with multiple sectors. Case studies addressing these root causes offer systemic solutions.
  • Indirect Impacts. Many case studies targeting other climate adaptation goals (e.g. urban heat reduction, flood resilience) may inadvertently address your problem.
  • Avoiding Unintended Consequences. Case studies highlighting trade-offs (e.g. coastal sand nourishment impacting ecosystems) underscore the need to evaluate how smoke mitigation measures might affect other sectors.
  • Involve Marginalized Communities. Case Studies that focus on harm reduction for marginalized communities may be limited. Utilizing an indirect approach to expand your research scope can help fill knowledge gaps and find crucial context about how to design equitable interventions.

EXAMPLE: WILDFIRE SMOKE & POLLUTION

  • Transferable Strategies. Stakeholder engagement frameworks from flood management or public health projects (e.g., participatory mapping, community engagement strategies, finding vulnerable populations) can be repurposed for smoke pollution planning.
  • Systemic Risk Reduction. Vehicle emissions testing reduced air pollution by targeting transport sector emissions, a strategy applicable to smoke from diesel engines.
  • Indirect Impacts. Exploring alternative mitigation strategies for issues like urban heat island (e.g., expanding green spaces) or flood resilience (e.g., installing green roofs) can introduce interdisciplinary solutions–such as the filtration of particulate matter from wildfire smoke.
  • Avoiding Unintended Consequences. Research shows that prescribed burns actively reduce wildfire prevalence, which in turn helps mitigate smoke pollution. However, prescribed burns themselves produce smoke which affects the surrounding environment, making the decision-making process more complex.
  • Involve Marginalized Communities. Case studies with census data on hospital visits, public health, and urban development trend can help contextualize the impacts of wildfire smoke on BIPOC communities.
