Status of the world’s soil resources

This report proposes an inventory of the soils of the planet, through several components: food security, water, climate change, human health and biodiversity. The main message is that the majority of the world's soil resources are in poor or very poor conditions: 33% of the land is degraded due to erosion, salinization, compaction, acidification and pollution chemical. Threats to soil are presented and policy recommendations are made.
