Conservation units and sustainable development goals: the private natural heritage reserves of Brazil

Knowledge and application of the Sustainable Development Goals (SDG) in the Private Natural Heritage Reserve management can help guide the sustainable use of the reserve's resources, whatever their identity and economic vocation. In addition, they ensure development with a focus on social, economic, and environmental concerns, as proposed in the 2030 Agenda. This study aims to investigate the relationship between the SDGs and the Brazilian PNHR management proposals, identifying the relevance and role of the PNHR in meeting the proposed goals by the year 2030. The study surveyed 142 PNHRs using a structured questionnaire in which their representatives assessed the level of relevance of the 17 SDGs regarding environmental conditions and local reality. The analysis compared the data concerning biomes and geographic region; cluster analysis was performed to observe similar responses, and principal component analysis to verify the relative importance between the scores assigned to the SDGs. The study created graphs based on the motivations for creating and using the PNHR. The PNHR showed alignment with the fulfillment of SDG 6 (Clean Water and Sanitation), SDG 13 (Climate Action), SDG 15 (Life on Earth), and SDG 3 (Good Health and Well-being). All respondents recognize discussions about the environment and sustainable development allied to nature conservation as a priority for achieving the SDGs. It is possible to recognize the importance of strengthening a space for coexistence between the local population and the PNHR to implement regular and transformative actions in favor of conservation and sustainable development.
