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.

Land degradation and poverty are problems that must be tackled together for environmental conservation to succeed. However, it is rarely possible to move a population from degraded land to another area where the people can be more easily sustained. To find a new strategy that achieves both conservation and economic gains without the need to relocate a population, we examined/investigated a sustainable combination of ecological and economic development suitable for the restoration of areas of China with collapsing gullies, where the frequent steep slopes make restoration difficult.
Stakeholder perceptions of recreational and management impacts on protected coastal dune systems: A comparison of three European countries
Coastal dune systems are particularly susceptible to destabilisation through recreational pressure and because of this, conflicts frequently arise between those who want to use the dunes for recreational purposes and those who wish to see these fragile ecosystems protected. In addition, a range of approaches to resolving this conflict are being used in different countries with differing levels of success. To study this conflict, an approach based on the Q-method was applied to three European Union Member States, i.e.
spectral gradient difference based approach for land cover change detection
Change detection with remotely sensed imagery plays an important role in land cover mapping, process analysis and dynamic information services. Euclidean distance, correlation and other mathematic metrics between spectral curves have been used to calculate change magnitude in most change detection methods. However, many pseudo changes would also be detected because of inter-class spectral variance, which remains a significant challenge for operational remote sensing applications.
role of seed provenance in the early development of Arbutus unedo seedlings under contrasting watering conditions
In the last decades, several studies have reported the increase of land degradation and desertification in the Mediterranean Basin. Depending on degradation severity, ecological restoration might be needed in order to promote ecosystem recovery. The ecology of the selected species and intra specific variability should be considered in order to improve restoration options, especially facing climate change. The present study tested the hypothesis that seedlings from drier provenances would be better adapted to low water content conditions.
Happiness is greater in natural environments
Links between wellbeing and environmental factors are of growing interest in psychology, health, conservation, economics, and more widely. There is limited evidence that green or natural environments are positive for physical and mental health and wellbeing. We present a new and unique primary research study exploring the relationship between momentary subjective wellbeing (SWB) and individuals’ immediate environment within the UK.
