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 356 - 360 of 1605Land institutions and supply chain configurations as determinants of soybean planted area and yields in Brazil
Soybean production has become a significant force for economic development in Brazil. It has also received considerable attention from environmental and social non-governmental organizations as a driver of deforestation and land consolidation. While many researchers have examined the impacts of soybean production on human and environmental landscapes, there has been little investigation into the economic and institutional context of Brazilian soybean production or the relationship between soy yields and planted area.
approach for characterizing the distribution of shrubland ecosystem components as continuous fields as part of NLCD
Characterizing and quantifying distributions of shrubland ecosystem components is one of the major challenges for monitoring shrubland vegetation cover change across the United States. A new approach has been developed to quantify shrubland components as fractional products within National Land Cover Database (NLCD). This approach uses remote sensing data and regression tree models to estimate the fractional cover of shrubland ecosystem components.
Landowners and conservation markets: Social benefits from two Australian government programs
Market-based approaches to conservation provide two novel policy outcomes. First, they secure public environmental benefits through incentive payments to private landowners to deliver those conservation outcomes that are unlikely to be achieved through regulation. Second, they provide opportunities to influence perceptions, motivations and values, and shift behaviors among landowners towards biodiversity conservation. Here we report on our experiences in engaging private landowners through two large market-based conservation programs funded by the Australian government.
assessment of long-term overtopping risk and optimal termination time of dam under climate change
Reservoir management faces a wide range of new challenges resulting from the impact of climate change. One set of challenges arises from the non-stationary nature of hydrological conditions. Another crucial issue is watershed sedimentation, which can significantly influence the sustainability and safety of reservoirs. To address these concerns, this study developed a framework for the management of reservoir risk. An analytical conceptual model coupling physical governing relationships and economic tools was proposed, which was then applied to the Shihmen Reservoir in Taiwan.
Regional impact assessment of land use scenarios in developing countries using the FoPIA approach: Findings from five case studies
The impact of land use changes on sustainable development is of increasing interest in many regions of the world. This study aimed to test the transferability of the Framework for Participatory Impact Assessment (FoPIA), which was originally developed in the European context, to developing countries, in which lack of data often prevents the use of data-driven impact assessment methods. The core aspect of FoPIA is the stakeholder-based assessment of alternative land use scenarios.
