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 European Union Rural Development Policy (RDP) for the period 2007–2013 seeks to establish a coherent and sustainable framework for the future of Europe's rural areas and is closely related to the improvement of living conditions in the countryside involving aspects of housing, the environment, infrastructure, communication, employment possibilities, land management, etc. Such interventions are very welcome in many Central and Eastern European countries where land reform after the collapse of the Soviet regime has resulted in a worrying drift towards rural depopulation.
Considering the multiple purposes of land in Zimbabwe's economic recovery
A preoccupation with the idea of land as a productive asset continues to dominate donor policy prescriptions imposed on poor nations of the world. The presumption is that a view of land as a productive asset implies security which then induces investment and improvements in agricultural productivity.
Mapping syndromes of land change in Spain with remote sensing time series, demographic and climatic data
The country of Spain is representative of land change processes in Mediterranean member states of the European Union (EU). These land change processes are often triggered by European, national and sub-national policies and include widespread land abandonment and urbanisation trends, as well as an increase in land use intensities accompanied by strong exploitation of water resources. The Mediterranean is part of the dryland ecoregion, which is particularly vulnerable to ecosystem degradation.
Modeling the response of within-storm runoff and erosion dynamics to climate change in two Mediterranean watersheds: A multi-model, multi-scale approach to scenario design and analysis
Climate change in the Mediterranean is expected to lead to lower total rainfall and soil moisture, together with higher storm intensities; different vegetation types are expected to react positively or negatively to these and other changes. Climate change could therefore have positive or negative impacts on runoff and soil erosion during storms, and previous research has indicated that the impacts could be different at the field, hillslope and catchment scales.
Comparing the relative contributions of biotic and abiotic factors as mediators of species’ distributions
Models to predict species’ ranges have chiefly been limited to abiotic variables. However, the full ecological niche depends on a myriad of factors, both biotic and abiotic, that often correspond to completely different data types. We applied a methodology based on data mining techniques to construct ecological niche models composed of biotic as well as abiotic variables using three quite different sets of variables: climatic layers, maps of land cover and point collections of Mexican mammals.
