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.

There has been renewed interest in the academic discourse on land reforms due to recent high profile works suggesting a positive correlation between reforms and poverty reduction. Land is held under different tenure regimes in different regions, countries and communities. These are often in the form of community tenure, state tenure, individual tenure or a mixture of two or three of them. However, land reformers are in constant debate as to which of the three offers the most appropriate pathway to poverty reduction.
Towards integration of 3D legal and physical objects in cadastral data models
Digital 3D cadastres are often envisaged as the visualisation of 3D property rights (legal objects) and to some extent, their physical counterparts (physical objects) such as buildings and utility networks on, above and under the surface. They facilitate registration and management of 3D properties and reduction of boundary disputes. They also enable a wide variety of applications that in turn identify detailed and integrated 3D legal and physical objects for property management and city space management (3D land use management).
Multivariate geostatistical methods for analysis of relationships between ecological indicators and environmental factors at multiple spatial scales
As all biodiversity-related variables, ecological indicators are influenced by environmental factors working at different spatial scales. However, assessing the relationship between environmental factors and ecological indicators is limited to a set of spatial scales determined a priori.
Hydrological response to climate variability at different time scales: A study in the Ebro basin
In this study we analyzed the response of monthly runoff to precedent climatic conditions at temporal scales of 1–48months in 88 catchments of the Ebro basin (northeast Spain). The standardized precipitation evapotranspiration index (SPEI) was used to summarize the climatic conditions at different time scales, and was correlated with the standardized streamflow index (SSI) calculated at the mouth of each catchment. The Ebro basin encompasses a gradient from Atlantic to Mediterranean climates, and has remarkable complexity in topography, geology and land cover.
Perception, demand and user contribution to ecosystem services in the Bilbao Metropolitan Greenbelt
Peri-urban ecosystems are often managed as recreation areas or to enhance aesthetic value on the urban fringe. Scholars and land-use practitioners lack a current understanding of the supply of and the demands for these peri-urban ecosystem services (ES). In this study, we analysed the perceptions of 500 users and interest groups regarding the ES provided by the Bilbao Metropolitan Greenbelt (BMG) ecosystems in northern Spain, and we compared these perceptions to the demands for ES. The objective of this study is to understand user preferences and to thereby better orient land use planning.
