The first part of this question is developing a list of problems facing the community. This list should draw on your answers to question 2 (environmental hazards) in particular and should be tailored to the type of environmental disaster (fast, slow, or combo) your case study is addressing. This list of problems should be the same as (or very similar to) the list you develop for question 8 (extra-local actions).
The second part of answering this question is looking at how the problems you have identified have been addressed in other places. In particular, question 7 focuses on local actions, which are actions at the city or county level (or even smaller units, like school or neighborhood). Question 8 focuses on extra-local actions, which are actions at the state, national, or international level.
The final part of answering this question is adapting solutions that have been successful in other locations to the local context of the specific community you are focused on. In order to do this effectively, researchers should take into account the local demographics (do residents have disposable income or are they living paycheck-to-paycheck? What language(s) are dominant?), the specific hazards faced by the community (which chemicals do nearby RMPs store? What are the anticipated impacts of climate change?), and existing local organizations and work that could support these actions.
