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.

Displaying 621 - 625 of 1605Pan-European distribution modelling of stream riparian zones based on multi-source Earth Observation data
Freshwater ecosystems are among the most degraded and threatened globally. A need for systematic assessment of riverine habitats is thus well-documented. Riparian zones are especially important due to the large array of ecosystem and social services they can provide, while also recently gaining a major role in the new European biodiversity policy. In this context, the necessity to gather spatial information on extent, distribution and characteristics of the riparian zones is clear.
Yield and water consumption characteristics of wheat/maize intercropping with reduced tillage in an Oasis region
Higher irrigation quota for conventional farming causes substantial conflicts between water supply and demand in agriculture, and wind erosion near soil surface is one of the major causes of farmland degradation and desertification in arid areas. This research investigated the effect of the amounts of irrigation in combination with tillage practices on soil evaporation (E), water consumption (ET) characteristics, and grain yield performance and water use efficiency (WUE) for wheat (Triticum aestivum L.) intercropped with maize (Zea mays L.) in strip planting in an Oasis region.
tool for mapping and spatio-temporal analysis of hydrological data
There is a need in water sciences for computational tools to integrate large spatially distributed datasets to provide insight into the spatial and temporal domains of the data while allowing visualization, analysis in the spatial and temporal dimensions, data metrics, and pattern recognition in the same application. Spatial and temporal variability of hydrological processes as well as the associated phenomena transport is better represented in high spatio-temporal resolution datasets.
Rural development and challenges establishing sustainable land use in Eastern European countries
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.
