Abstract
The research investigates the link between environmental information and environmental policies, pointing out how, even now, complexity in creation, capture and analysis of first ones makes difficult building knowledge basis for decisions, in spite of variety of available tools with several analytical capabilities. Particularly, research introduces an analysis of criticisms related to environmental information, among which its fragmentary nature, high variety of sources, incompleteness, difficult accessibility, validation lack, multiple formats etc., and, considering policy cycle, it proposes some paths to strengthen the link between environmental information and policies. These paths have been defined in a context characterized by an increasing spread of information and communication technologies; these, moreover, now open also to new scenarios, where citizen science and volunteer geographic information become new and additional sources of information, even if not official, for environmental and not only environmental data, useful to fill potential incompleteness.
