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.

This study explores the factors that influence obtaining forest certification in the U.S. Pacific Northwest (PNW). A mail survey sent to certified and non-certified forest managing entities (public agencies, forest industry and non-industrial private forest owners) was conducted. The study hypothesized the importance of sixteen biogeographical and socio-economic factors in facilitating the adoption of forest certification. Three of these factors (market pressure, land ownership pattern and water-body abundance) were found to influence the decision to obtain forest certification in the U.S.
District-scale prioritization for A/R CDM project activities in Indonesia in line with sustainable development objectives
The promise of the Clean Development Mechanism (CDM) to deliver its dual objectives is currently under public scrutiny. In land-use, land-use change and forestry (LULUCF) activities through afforestation and reforestation projects, known as A/R CDM, the deliverables that demonstrate sustainable development remain unclear. While the methods to convincingly demonstrate carbon benefits are fine-tuned, there is growing concern on a lack of socio-economic benefits of the projects.
Forest restoration in an indigenous land considering a forest remnant influence (Avaí, São Paulo State, Brazil)
The expansion of agricultural and pasture areas over native forest areas has been broadly documented and represents the main cause of deforestation that has occurred for the last decades. Such reality is not different in indigenous lands, and has been considered as an important obstacle for individuals who directly depend upon the appropriate management of natural resources to maintain their traditions.
Carbon accumulation and storage in semi-arid sagebrush steppe: Effects of long-term grazing exclusion
The potential of grazing lands to sequester carbon has been investigated in different terrestrial environments but the results are often inconclusive. Our study examined the soil organic carbon (SOC) and soil microbial biomass carbon (MBC) contents inside and outside four grazing exclosures that had been established more than four decades ago in the semi-arid sagebrush steppe of Wyoming.
Changes over three decades in the floristic composition of fertile permanent grasslands in the Swiss Alps
This study investigates how the floristic composition and species richness of fertile grasslands in the Swiss Alps has changed over the last three decades. A total of 259 phytosociological relevés in four regions were resurveyed after periods of between 17 and 29 years. Analysis of the data revealed that floristic composition of the grasslands changed significantly during the study period, although the factor 'time' explained only a small proportion of the total variation (2.0-4.1%).
