Traditionally, social intervention and environmental intervention have been conceptualized as distinct and independent fields of action, sharing certain points of intersection but characterized by separate and unconnected methodologies and strategic approaches. However, the notion of sustainability definitively integrates both dimensions as manifestations of a single, overarching issue.

From this perspective, the foundational premise of this programme is that individuals, communities, and their environments constitute an inseparable and interdependent global unit, wherein the various components are inextricably linked and mutually constitutive, giving rise to an integrated structure. Consequently, any environmental intervention must necessarily account for psychological and social dimensions, insofar as individuals, groups, and communities are ultimately the subjects affected by—and the beneficiaries of—transformations in the physical environment.

Similarly, all social interventions must incorporate the environmental factors inherent in the context, given that such actions are never undertaken in isolation but rather within a defined socio-physical setting. Within this framework, environmental education and awareness-raising emerge as key mechanisms for reconciling the relationship between environmental transformation and human development—both personal and collective—culminating in what may be broadly termed sustainable psycho-socio-environmental development.
