Elsevier is a world-leading provider of information solutions that enhance the performance of science, health, and technology professionals.
All knowledge begins as uncommon—unrecognized, undervalued, and sometimes unaccepted. But with the right perspective, the uncommon can become the exceptional.
That’s why Elsevier is dedicated to making uncommon knowledge, common—through validation, integration, and connection. Between our carefully-curated information databases, smart social networks, intelligent search tools, and thousands of scholarly books and journals, we have a great responsibility and relentless passion for making information actionable.

Displaying 96 - 100 of 1605Greenbelts in Germany's regional plansâAn effective growth management policy?
Greenbelts are the best-known growth management policies in Germany. As part of its regional plans, they attempt to keep undeveloped areas permanently open, thus avoiding sprawling, i.e., land consumptive forms of urban development. However, the effectiveness of such land use designations in terms of guiding and limiting urban growth has rarely been the subject of in-depth research. This is the first study to present a GIS-based analysis of the restrictiveness of greenbelt designations in Germany and their impact on urban spatial structure and land use.
Implications of land cover change on ecosystems services and peopleâs dependency: A case study from the Koshi Tappu Wildlife Reserve, Nepal
Protected areas, a corestone of biodiversity conservation, provide a vast array of ecosystem services to support livelihoods of people. However, protected areas, especially freshwater, are under threat with overexploitation of resources changing the land covers and degrading their capacity to supply services. Information on land cover changes and its implications on ecosystems, its services and people, especially in developing countries at a local scale, is largely absent.
Surface energy exchange in a tropical montane cloud forest environment: Flux partitioning, and seasonal and land cover-related variations
Relationships between seasonal climate, land cover and surface energy exchange in tropical montane cloud forest environments are poorly understood. The goal of this study was to investigate the seasonality of flux partitioning in lower montane cloud forest (LMCF), shaded coffee (CO) and sugarcane (SU) in central Veracruz, Mexico, as well as to evaluate the changes in surface energy exchange associated with the conversion of LMCF to CO or SU.
Trees, grass, and fire in humid savannasâThe importance of life history traits and spatial processes
We develop a model to investigate how trees can invade the grass stratum in humid savannas despite repeated fires. In the literature, it is clear that fire reduces tree canopy in savannas. However, fire alone may not be sufficient to prevent tree invasion because there are ecological mechanisms that hamper fire spread by undermining the continuity and density of the grass stratum, which is the means of fire propagation in savannas.
Participatory mapping to identify indigenous community use zones: Implications for conservation planning in southern Suriname
Large-scale development projects often overlap forest areas that support the livelihoods of indigenous peoples, threatening in situ conservation strategies for the protection of biological and cultural diversity. To address this problem, there is a need to integrate spatially-explicit information on ecosystem services into conservation planning. We present an approach for identifying conservation areas necessary to safeguard the provision of important ecosystem services for indigenous communities.
