Shared Environmental Information System and Single InformationSpace in Europe for the Environment: Antipodes or Associates?

This paper outlines the background of SEIS and SISE, and identifies similarities and disparities in their objectives. The paper stresses clearly that collaboration between SEIS and SISE in the sense of a partnership would be ecologically worthwhile. However, any parallel development, divergence or antagonism would mean a dissipation of valuable resources and a drawback for sustainable development.
