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.

Accelerated soil erosion, high sediment yields, floods and debris flow are serious problems in many areas of Iran, and in particular in the Golestan dam watershed, which is the area that was investigated in this study. Accurate land use and land cover (LULC) maps can be effective tools to help soil erosion control efforts.
How and why forest managers adapt to socio-economic changes: A case study analysis in Swiss forest enterprises
Forestry is an important source of income for forest owners and those employed in rural areas. In recent years, this sector has had to tackle far-reaching changes taking place in the social, economic and political system. New demands are now being addressed and policies reformulated. As a response to this pressure, new decision-making structures and innovation activities are taking place in the forestry sector. The aim of this paper is to study learning processes on the management level of forest enterprises.
cloud mask methodology for high resolution remote sensing data combining information from high and medium resolution optical sensors
This study presents a novel cloud masking approach for high resolution remote sensing images in the context of land cover mapping. As an advantage to traditional methods, the approach does not rely on thermal bands and it is applicable to images from most high resolution earth observation remote sensing sensors. The methodology couples pixel-based seed identification and object-based region growing. The seed identification stage relies on pixel value comparison between high resolution images and cloud free composites at lower spatial resolution from almost simultaneously acquired dates.
REDD+, transparency, participation and resource rights: the role of law
One of the crucial questions which emerges in the context of REDD+ is how the rights of indigenous peoples and local communities will be protected. These rights include the rights of sharing in the financial benefits of REDD+, the rights to participate in decision-making around REDD+ schemes, and the rights to have their knowledge about forestry resources respected. Each of these issues depends on the extent to which they have some sort of claim to, or tenure over, tropical rainforests.
Adapting a global stratified random sample for regional estimation of forest cover change derived from satellite imagery
A desirable feature of a global sampling design for estimating forest cover change based on satellite imagery is the ability to adapt the design to obtain precise regional estimates, where a region may be a country, state, province, or conservation area. A sampling design stratified by an auxiliary variable correlated with forest cover change has this adaptability. A global stratified random sample can be augmented by additional sample units within a region selected by the same stratified protocol and the resulting sample constitutes a stratified random sample of the region.
