Biodiversity in rangelands is decreasing, due to intense utilization
for livestock production and conversion of rangeland into cropland;
yet the outlook of rangeland biodiversity has not been
considered in view of future global demand for food. Here we
assess the impact of future livestock production on the global
rangelands area and their biodiversity. First we formalized existing
knowledge about livestock grazing impacts on biodiversity,
expressed in mean species abundance (MSA) of the original

Land degradation and desertification are among the biggest environmental challenges of our time. In the last 40 years, we lost nearly a third of the world’s arable farmland due to erosion, just as the number of people to be fed from it almost doubled. That’s why the UN General Assembly declared 2015 as the International Year of Soils. And the good news is that this new report shows that while Africa remains the most severely a«ected region, the benefit of taking action across the continent outweighs the cost of implementing it: not just by a little, but by a factor of seven.

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species’ threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project – and avert – future declines.

Few regions present bigger development challenges than the African drylands – home to nearly 300 million people, and the vast majority of Africa’s poor. Food security and rural welfare in these areas are limited by a range of factors, biophysical, socio-economic and policy-related. And many of the biggest challenges – poverty, drought, land degradation, food insecurity – will be exacerbated by climate change.
