But urban development poses a risk of losing urban ecosystems and their services to inhabitants. Hence, urban green spaces need to be integrated into urban planning and decision making in a systematic way. Urban ecosystem accounting (EA) provides a framework for quantifying changes in the extent and the condition of urban ecosystems and for assessing change in the ecosystem service supply and use over time. As a result, EA provides an information system that can support municipal planning and policy. This report describes a few pilots carried out in Finland and Norway and proposes a draft roadmap for future urban ecosystem accounting in Nordic cities.
Finland's special characteristics as a Nordic, non-aligned welfare state gave it the resources and motivation to support liberation movements - in spite of restrictions arising from trade interests and a reluctance to jeopardise the country's neutral image. The study shows that, although it is not an easy task, in a democracy ordinary, dedicated people can, over time, influence political decision making at its most closed and guarded area, foreign politics.
The indigenous cloud forests in the Taita Hills have suffered substantial degradation for several centuries due to agricultural expansion. Additionally, climate change imposes an imminent threat for local economy and environmental sustainability. In such circumstances, elaborating tools to conciliate socioeconomic growth and natural resources conservation is an enormous challenge. This chapter describes applications of remote sensing and geographic information systems for assessing land-cover changes in the Taita Hills and its surrounding lowlands. Furthermore, it provides an overall assessment on the consequences of land-cover changes to water resources, biodiversity and livelihoods. The analyses presented in this study were undertaken at multiple spatial scales, using field data, airborne digital images and satellite imagery. Furthermore, a modelling framework was designed to delineate agricultural expansion projections and evaluate the future impacts of agriculture on soil erosion and irrigation water demand.
