|Description=As a result of the growing world population and higher per capita consumption, production of food, feed, fibres and other products, such as bio-energy and timber will need to increase rapidly in the coming decades. Even with the expected improvements in agricultural yields and efficiency, there will be increasing demand for more agricultural land. However expansion of agricultural land will lead to increases in greenhouse gas emissions, loss of biodiversity and ecosystem services, and nutrient imbalances. To reduce these environmental impacts, action is needed urgently to increase agricultural yields further and to reduce deforestation requires political support. | |Description=As a result of the growing world population and higher per capita consumption, production of food, feed, fibres and other products, such as bio-energy and timber will need to increase rapidly in the coming decades.

Key policy issues
- What is the area of cropland and grassland required to support future food demand?
- What are the policy options to reduce agricultural land use and to safeguard global biodiversity, while ensuring food security?
- How can the implications of biofuels for land use and greenhouse gases be managed sustainably?
