Food security and food production systems
Many definitions of food security exist, and these have been the subject of much debate. As early as 1992, Maxwell and Smith (1992) reviewed more than 180 items discussing concepts and definitions,…
The performance and potential of protected areas
A step change involving increased recognition, funding, planning and enforcement is urgently needed if protected areas are going to fulfil their potential.
Conservation biogeography: assessment and prospect
The role played by biogeographical science in the emergence of conservation guidance is examined and the case for the recognition of Conservation Biogeography as a key subfield of conservation biology delimited as both a substantial body of theory and analysis is made.

A comprehensive summary of studies that simulate climate change impacts on agriculture are now reported in a meta-analysis. Findings suggest that, without measures to adapt to changing conditions,…
Assessing species' vulnerability to climate change
The effects of climate change on biodiversity are increasingly well documented, and many methods have been developed to assess species' vulnerability to climatic changes, both ongoing and projected…
Biodiversity: The ravages of guns, nets and bulldozers
An analysis of threat information gathered for more than 8,000 species revealed that overexploitation and agriculture are by far the biggest drivers of biodiversity decline.
From Publications to Public Actions: When Conservation Biologists Bridge the Gap between Research and Implementation
It is argued that a conceptual paradigm shift should take place in the academic conservation discipline toward more commitment on the part of researchers to turn conservation science into conservation action, and practical implementation should be regarded as an integrated part of scientific conservation activity.
The broad footprint of climate change from genes to biomes to people
The full range and scale of climate change effects on global biodiversity that have been observed in natural systems are described, and a set of core ecological processes that underpin ecosystem functioning and support services to people are identified.
One-third of global protected land is under intense human pressure
Use of the most comprehensive global map of human pressure shows that 6 million square kilometers (32.8%) of protected land is under intense human pressure, showing that they are potentially effective, at least in some nations.
Sixteen years of change in the global terrestrial human footprint and implications for biodiversity conservation

This work uses recently available data on infrastructure, land cover and human access into natural areas to construct a globally standardized measure of the cumulative human footprint on the terrestrial environment at 1 km2 resolution from 1993 to 2009.
