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 1456 - 1460 of 1605Swedish forest commons — A matter of governance
Around 100years ago, when Crown land in the interior of northern Sweden was privatized, part of the forest land was set aside as forest commons. Today, there are 33 such forest commons jointly managed and owned in common mainly by private forest owners. The forest commons may be looked upon as a means by which the state controls the production of and returns from the forests belonging to small and less affluent forest owners. Further, an attempt has been made to use the forests as a tool to move the self-interests of these small forest owners closer to providing public goods.
Wood-to-energy expansion, forest ownership changes, and mill closure: Consequences for U.S. South's wood supply chain
The U.S. South's wood supply chain has undergone major changes over the past two decades in terms of forestland ownership and forest industry structure. Recent interest in producing energy from wood has raised questions about how a vibrant wood-energy market will impact the traditional southern wood supply chain. By using a survey of consulting foresters, this study examined how harvest tract size, forest ownership, and forest industry structure have changed within the U.S. South and how foresters expect the wood-energy market to impact the wood supply chain in the future.
Management strategies for maximizing carbon storage and tree species diversity in cocoa-growing landscapes
How do we manage the trade-offs between agricultural yields, biodiversity and ecosystem services? One option is to adopt high yield, intensive farming that allows land to be spared elsewhere for conservation (land sparing); another is to adopt low yield, extensive farming over a greater area that retains more biodiversity and protects ecosystem services (wildlife-friendly farming). We examine which is likely to be the best option to achieve high carbon storage and tree species richness in tropical cocoa-growing landscapes.
Impacts of extensive grazing and abandonment on grassland soils and productivity
Two long-term (16 year) experiments on intensively managed pastures compared extensive grazing, abandonment and continued intensive grazing and were assessed for impacts on soil parameters, plant nutrient content and ecological indicator values. There was a reduction in soil carbon and nitrogen in the abandoned treatment compared to the intensively managed treatment at the wetter site. At the drier site, extensive grazing resulted in a build up of soil carbon. There was a build up of dead organic matter and a reduction in the nutritive value of the vegetation as grazing was reduced.
Web-based system for vineyards management, relating inventory data, vectors and images
A Web-based system is presented, integrating spatial information from remote sensing images, GPS measurements and inventory data. Monitoring, research and management of the grape production at Rio Grande do Sul State, Brazil (624,000 metric tons in 2006) can be done through a system entirely based in open-source codes.
