A Community-Based Intervention Proposal for Municipal Solid Waste Management: Analyzing Willingness, Barriers and Spatial Strategies

Municipal Solid Waste (MSW) management programs can help to mitigate the triple planetary crises of climate change, biodiversity loss and pollution. However, their success largely depends on the public willingness to engage in the pro-environmental separation anddelivery of MSW,particularly for difficult-to-manage items such as electronics, batteries and appliances, which often contain toxic materials. Most existing research tends to focus on infrastructure improvements or behavioral interventions, with little integration of psychosocial and contextual analyses to develop evidence-based strategies for increasing community participation in the sustainable management of MSW. To address this gap, we conducted a study combining quantitative data from surveys with qualitative and geospatial data obtained through social mapping sessions and information obtained from local waste collectors in five municipalities in Norte de Santander, Colombia—a region marked by high socioeconomic vulnerability. Our study presents a novel integration of psychosocial and geospatial data to inform MSW interventions in low-resource settings. We identified that the awareness of the consequences of poorMSWmanagement,theawareness of environmental benefits of delivery and the subjective norm predicts the willingness to separate and deliver MSW. Nonetheless, various psychosocial and contextual barriers hinder these actions. Based on these insights, we propose a low-cost, community-tailored intervention to enhance the separation and delivery of difficult-to-manage MSW and foster civic engagement in similar socio-environmental contexts.
