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 global poor often prioritise immediate hazards of food insecurity over temporally more distant risks like global warming. Yet the influence of socio-economic factors, temporal and spatial distance on risk perception remains under-researched. Data on risk perception and response were collected from two sets of Indian villages. Participatory approaches were used to investigate variations by socio-economic status, food security, age and gender. Villagers’ risk priorities reflected clear spatial and temporal patterns depending on land ownership, community group and education levels.
review of the role of property rights and forest policies in the management of the Sundarbans Mangrove Forest in Bangladesh
The purpose of this paper is to critically evaluate past forest management policies and property rights regimes in achieving sustainability of the Sundarbans Mangrove Forest (SMF) in Bangladesh. The adequacy of forest policies to reflect regimes of property rights in their design and implementation is examined using content analysis. The analysis synthesises forest policies of four distinct historical time periods, and the embedding of property rights during those periods using Schlager and Ostrom's typology.
Effects of land management on CO₂ flux and soil C stock in two Tanzanian croplands with contrasting soil texture
Evaluation of carbon dynamics is of great concern worldwide in terms of climate change and soil fertility. However, the annual CO₂ flux and the effect of land management on the carbon budget are poorly understood in Sub-Saharan Africa, owing to the relative dearth of data for in situ CO₂ fluxes. Here, we evaluated seasonal variations in CO₂ efflux rate with hourly climate data in two dry tropical croplands in Tanzania at two sites with contrasting soil textures, viz. clayey or sandy, over four consecutive crop-cultivation periods of 40 months.
accidental outcome: Social capital and its implications for Landcare and the “status quo”
For 25 years the Australian Landcare program has encouraged rural land managers to work cooperatively to resolve natural resource management issues across the nation. Landcare has spread and the model is used internationally. Despite its successes, Landcare has come under criticism for not sufficiently directing land management practices towards environmental sustainability. This criticism sees it as having maintained the “status quo”.
Testing the effect of site selection and parameter setting on REVEALS-model estimates of plant abundance using the Czech Quaternary Palynological Database
REVEALS-based quantitative reconstruction of Holocene vegetation cover (expressed in plant functional types, PFTs) is used in the LANDCLIM project to assess the effect of human-induced land-cover change on past climate in NW Europe. Using the Czech Quaternary Pollen Database, this case study evaluates the extent to which selection of data and input parameters for the REVEALS model applications would affect reconstruction outcomes.
