This chapter examines the factors enabling community-based organizations (CBOs) to prioritize socio-ecological concerns despite operating within contexts dominated by unsustainable production-consumption systems. The analysis identifies key success factors including ethical coordination mechanisms, open organizational design, autonomy-supportive settings, and recognition of diverse values. Significant barriers include material constraints, legal-administrative challenges, financial pressures, capability gaps, and systemic forces. The chapter explores pathways for adapting and amplifying community-based approaches through context-sensitive implementation, acknowledging multiple valid organizational origins, and providing adequate time and knowledge resources. The findings offer implications for reorganizing economic activities, rethinking organizational management beyond surplus primacy, and catalyzing social change through cultural transformation. A research agenda is proposed to further explore how collective action can be organized to meet needs sustainably while respecting ecological boundaries.
