Strong sustainability, critical natural capital and the capability approach

- This paper aims to improve the implementation of strong sustainability (SS)
- It analyses the linkage between well-being and critical natural capital (CNC) through the capability approach (CA).
- The rapprochement between CNC and CA form both the normative basis and the informational basis for implementation of SS.
- This paper opens up avenues of research towards the practical implementation of human development from a SS perspective.

This article is an attempt to conceptually improve the notion of strong sustainability by creating a rapprochement between its core concept, critical natural capital, and the capability approach. We first demonstrate that the capability approach constitutes a relevant framework for analysing the multiple links between human well-being and critical natural capital. Second, we demonstrate that the rapprochement between critical natural capital and the capability approach can form both the normative basis and the informational basis for a deliberative approach to human development which embraces a strong sustainability perspective. This conceptual rapprochement, as illustrated in our case study, opens up avenues of research towards the practical implementation of human development projects from a strong sustainability perspective.
