Recent strong commodity prices have led to rising demand for farmland and this is projected to continue for the medium term because of increasing populations and incomes and growing use of biofuels. Global analysis indicates that about 450 Mha of suitable land may be available to bring into...

Mining of energy resources and minerals is clearly the running down of a large but finite, and non-renewable, resource. It is important also to recognise the nonrenewable aspects of food production: in particular, net consumption of nutrients and soil as well as the direct and embodied...

Global rates of deforestation and forest degradation continue at persistently high levels, although annual net rates of forest loss have slowed to approximately 8 Mha as the extent of planted forests increases. Drivers of deforestation vary geographically. Conversion to both large- and...

The main drivers of tropical forest biodiversity loss are land clearing for agriculture, pasture and timber plantation development, followed by logging activities that degrade forests. Deforestation and forest degradation also significantly contribute to climate change, given that they...
