Using citizen science to empower older adults to improve a food security initiative in Australia.

Food security is an increasing problem for older adults who are living longer and having to stretch their resources further. Initiatives such as subsidized community market days are increasingly important in bolstering food security amongst these groups but there have been few attempts to understand these initiatives from the perspective of community members. This exploratory study examined the utility of a novel citizen science approach to engage older adults in evaluating and improving a local food security initiative. Using the Our Voice methodology, citizen scientists recorded their perceptions of their local Market Day via photographs and audio narratives. Thirteen citizen scientists captured 127 photographs and 125 commentaries. Citizen scientists participated in workshops to discuss, code and synthesize their data, and used their findings to advocate for change. A number of improvements to the Market Day were made by key stakeholders on the basis of citizen scientist recommendations, including improving the processes for sourcing and storing food and changing the layout to improve access. This study demonstrates that citizen science is a useful and feasible approach to engaging community members in capturing data and advocating for change to ensure that local initiatives meet the needs of communities.
