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.

Elandskloof was the first land restitution case in post-apartheid South Africa in which the government returned land to a community. The communal property association became dysfunctional, and the courts placed it under government administration. In its haste to return land to the community in the aftermath of the apartheid system the state did not set up comprehensive planning and consultative processes within government institutions, the beneficiary community and NGOs before returning the land.
Geomapping generalized eigenvalue frequency distributions for predicting prolific Aedes albopictus and Culex quinquefasciatus habitats based on spatiotemporal field-sampled count data
Marked spatiotemporal variabilities in mosquito infection of arboviruses require adaptive strategies for determining optimal field-sampling timeframes, pool screening, and data analyses. In particular, the error distribution and aggregation patterns of adult arboviral mosquitoes can vary significantly by species, which can statistically bias analyses of spatiotemporal-sampled predictor variables generating misinterpretation of prolific habitat surveillance locations.
Presence of Iberian wolf (Canis lupus signatus) in relation to land cover, livestock and human influence in Portugal
From June 2005 to March 2007, we investigated wolf presence in an area of 1000km² in central northern Portugal by scat surveys along line transects. We aimed at predicting wolf presence by developing a habitat model using land cover classes, livestock density and human influence (e.g. population and road density). We confirmed the presence of three wolf packs by kernel density distribution analysis of scat location data and detected their rendezvous sites by howling simulations. Wolf habitats were characterized by lower human presence and higher densities of livestock.
Managing urban growth in a transforming China: Evidence from Beijing
Managing urban growth in the current rapid urbanization process has become a key issue for land use policy in transformation China. This paper maps and assesses the performance of urban containment strategies in China, looking at the case of Beijing over a 19-year period (1990–2009). The analysis shows that to a large extent containment strategies perform well in terms of concentrating urban growth in planned suburban areas and promoting compact development.
Using the CENTURY model to assess the impact of land reclamation and management practices in oasis agriculture on the dynamics of soil organic carbon in the arid region of North-western China
Large-scale reclamation of arid land in North-western China over the past 50 years has converted the natural desert landscape into anthropogenic oasis, particularly in the lower part of watersheds. Drastic human activities may have caused the change of soil organic carbon (SOC) in anthropogenic oasis. This study employs the CENTURY model (Version 4.0) to investigate the effects of land reclamation and management practices in oasis agriculture on the dynamic of SOC at the lower part of Sangong river watershed, a typical anthropogenic oasis reclaimed at 50 years ago.
