Soil

Soil is a precious and scarce natural resource. More than 99 per cent of food world-wide comes from soil ecosystems. Land, of which soil is a key component, not only provides food, but plays a key role in regulating water and the global carbon budget, and is a valuable source of biodiversity. However soils around the world are degrading rapidly, threatening food and other securities and increasing vulnerability to climate change. We need sustainable land management practices, e.g. an integrated soil, land, and water management.
