5. Abstract

Sustainability in the context of regional development requires and implies that the population be provided with an adequate supply of nutrition produced on an ecoiogically sound basis and within a healthy
economic and social order.

The regional approach creates great potential for sustainable development to include poor sections of the popuiation. This applies particularly to marginal locations, where Sustainability can only be achieved through a package of measurcs. These include traditional strategies to secure livelihoods, interregional adjustrnent, subsidies and migration of population groups. And it is imperative that back-up measures be provided to ensure socially responsible land-use and utilisation of resources.
