Sustainable development implies a radical reconfiguration of patterns of production and consumption, and changes in the relationship between societies and the natural environment. It therefore requires the structural transformation of economies, especially in LDCs, which need to transition to high-productivity economic activities and sectors in order to tackle the traditional challenges of economic and social development in a new way that mainstreams environmental considerations. The concept of sustainable development links three dimensions of sustainability — economic, social and environmental — and the 2030 Agenda emphasizes the unity of, and mutual support between, these dimensions.
