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.

The ongoing forest biodiversity protection programme in Finland (METSO) relies on voluntary participation of family forest owners. Even though the programme has gained wide acceptability among owners, compared to traditional conservation such as land acquisition, more owners need to be engaged. In this study, we examined how the new protection measures have diffused among forest owners. This analysis will help find means to promote the protection among owners who could but have not yet participated. The theoretical background is innovation diffusion.
relevance of governance models for estuary management plans
The latest theories on the governance of water resources point to the need to adopt integrated approaches, allowing the mediation of conflict between public and private interests by building consensus to include the participation of stakeholders and civil society in formulating and implementing policies, thereby ensuring their legitimacy. Models of governance have particular relevance in the context of estuaries, because of the complexity associated with them.
Assessment of the biomass energy potentials and environmental benefits of Jatropha curcas L. in Southwest China
Jatropha curcas L. (JCL) is believed to be the most promising tree species used to produce biodiesel in China. Due to its abundant marginal land resource and good meteorological conditions, Southwest China is the major region to develop JCL. With Southwest China being taken as the study area in this paper, multi-factor comprehensive analysis is used to identify marginal land resources suitable to JCL plantation and make suitability assessment, thus obtaining their spatial distribution, suitability degree and total amount.
Landscape functionality in protected and unprotected areas: Case studies from the Czech Republic
Landscape structure not only reflects the natural settings of the landscape but also its history and the impact of human activity. Information about the characteristics of the landscape elements in terms of their structural functionality plays a central role in assessing their ecological quality. Statutory designation of sites plays a key role in conserving and maintaining valuable parts of the landscape. In this study, we investigated whether protection status influences functionality in case studies from the Czech Republic, representing three different landscape types.
Carbon sequestration and water use of a young hybrid poplar plantation in north-central Alberta
Hybrid poplar (HP) is an important fast-growing crop with the potential to provide a reliable supply of biomass for the pulp and bioenergy industries while also sequestering carbon (C) in the soil. We used the eddy-covariance technique to measure CO₂, water vapor and sensible heat fluxes above a three-year-old HP plantation on high productivity land near St Albert, Alberta. Measurements showed that the annual C balance of the plantation shifted from a C source of about 1.54 Mg C ha⁻¹ y⁻¹ in the 2nd year (2010) to a C sink of 0.80 Mg C ha⁻¹ y⁻¹ in the 3rd year (2011).
