The 2030 Agenda has influenced the design of public policies in Colombia and other countries in the region, but there are many gaps in the way a global policy can be interpreted and adapted to the territories. Thus, this article aims to critically evaluate the public policy of sustainability implemented in the Colombian Caribbean and to suggest contributions from an intercultural socioenvironmental justice perspective. For this purpose, the public policy of sustainability that orients the plans for the use of insular ecosystems in Cartagena de Indias has been examined and confronted with local evidence that shows significant changes in the forms of life and ecological degradation in multi-temporally analysed coverages. Methodologically, this research is based on three aspects: the theoretical discussion of the notions of sustainability and justice in public policies, spatial databases to analyse the transformation of landscapes and ethnographic work with Afro-descendant peoples to recognise their socioecological systems. We found that the public policy of territorial planning aligned with the 2030 Agenda nominally includes a rights approach, but management practices or governance structures do not consider the very high asymmetry in land tenure, the growing private and non-participatory regulation of coasts and the sea or the exclusion of Afro-descendant peoples who claim tenure and autonomy rights. Then, we propose integrated dimensions of sustainability that overcome the socioecological negativity observed and articulate criteria of intercultural justice in public, social and environmental policies.
