Abstract
Ecuadorian primates are a diverse and ecologically important group that is facing severe conservation problems. We present the experiences and lessons learned from two primate conservation projects in eastern and western Ecuador to foster an in-depth reflection of what could be improved to enhance their contribution to the delivery of the Sustainable Development Goals (SDGs). By combining research, education, and capacity building, both projects aim to empower and engage local communities in initiatives to protect primate habitats. These efforts to enhance local environmental sustainability contribute to SDGs 15 (Life on land), 4 (Quality of education), 2 (Zero hunger), 3 (Good health and well-being), 5 (Gender equality), 10 (Reduced inequalities), 12 (Responsible consumption and production), and 13 (Climate actions). One of our findings is that community involvement in conservation activities is not always directly related to an improvement of the conservation status of primate populations. Therefore, continuous monitoring of primate populations and of other relevant indicators is key to assessing the effectiveness of the interventions. We highlight the importance of sharing information between projects with similar scopes and the need to develop local indicators for a more objective assessment of the contribution of small-scale conservation projects to the delivery of the SDGs.
