In May 1999, ministers of the EU Member States, responsible for spatial planning, have approved the European Development Perspective (E.S.D.P.). This document is a result of a new mode of European co-operation, although the documents in the field of spatial planning do not provide any new responsibilities at the Community level. This document has been built on the base of a set of the documents, such as CEMAT – Document, EUROPA 2000, EUROPA 2000+, European Spatial Planning Charter, etc. The E.S.D.P. and the other mentioned documents identify principles of spatial planning, policy objectives and options "for a balanced and polycentric system of towns and cities, interconnected transport and communications infrastructure and for development of the cultural and natural heritage" (and in this context for the cultural landscape, too). In these documents, the landscape planning has been mentioned as an integrated part of the spatial planning. They call for re-evaluation of the partnership between city and countryside with the aim of forming an integral view of urban, rural and landscape areas and for formulating of the principles for sustainable spatial development of landscape systems as a part of supraregional, regional and urban systems.
