Area development still lacks a firm theoretical basis. Sustainable area development means that the society the value of landscape determines by weighing of ecological, social and economic aspects.

The intention is that by adjusting the physical landscape it functions in an way that the intended value actually occurs. This principle is hardly applied in practice. Possible causes: the lack of an integral (physical-social) system concept, and the lack of methods for collective planning.

The aim of the EU project Green Infrastructure For Tomorrow - Together! (GIFT-T!) is to develop a method based on Green-blue veining, landscape services and collective action. This method provides insight into how local communities can make a plan for sustainable development of their landscape, and simultaneously contribute to regional scale connectivity between Natura 2000 areas. Together with local companies they make a business plan in which the financing is arranged.

The result of the project is the implementation of sustainable development in planning policy. We show how landscape can again play a functional role in society, as a physical system which create economic, social and ecological value in the interest of many parties.
