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.

In this paper, it is shown how a system can be created by using methods of Artificial Intelligence, designated (a) to provide the user with information about the transformations of Mediterranean-type landscapes in an interactive way, (b) to allow the modelling of causes and effects of landscape transformations (such as land degradation) and (c) to forecast future landscape changes. The system consists of programs, which run independently. Each module performs a certain task only and contributes to the modelling of landscape transformations in a different way.
Phenological dynamics of irrigated and natural drylands in Central Asia before and after the USSR collapse
Central Asia has experienced drastic socio-economic, geopolitical, and ecological transitions within the last few decades. The USSR collapse in 1991 has led to widespread changes in land cover and land use due to economic and political transformations within the region. Management practices during and after the Soviet era have intensified ecological problems and demands on resources.
Effect of land management on soil microbial N supply to crop N uptake in a dry tropical cropland in Tanzania
In Sub-Saharan Africa, conservation of available soil N during early crop growth, when N loss by leaching generally occurs, is important to improve crop productivity. In a dry tropical cropland in Tanzania, we assessed the potential role of soil microbes as a temporal N sink–source to conserve the available soil N until later crop growth, which generally requires substantial crop N uptake.
Rural–urban gradient analysis of ecosystem services supply and demand dynamics
Urban regions are important places of ecosystem service demands and, at the same time, are the primary source of global environmental impacts. Although there is broad agreement on the importance of incorporating the concept of ecosystem services into policy strategies and decision-making, the lack of a standardized approach to quantifying ecosystem services at the landscape scale has hindered progress in this direction. Moreover, tradeoffs between ecosystem services and the supply/demand ratio of ecosystem services in urban landscapes have rarely been investigated.
Capitalization by formalization? – Challenging the current paradigm of land reforms
Most of the land reforms in developing countries in recent decades follow a blueprint that is based on the property rights theory. This blueprint was supported by Western government-backed development aid institutions and the World Bank and intends to achieve a capitalization of property rights on land by formalization and individualization. Its supporters expect higher efficiency of the land markets and higher tenure security. The focus of the article is not so much on the formalization efforts themselves, but on the capitalization of the use rights.
