Status of the World's Soil Resources. Technical Summary

This document presents a summary of the first Status of the World's Soil Resources report, the goal of which is to make clear the essential connections between human well-being and the soil. The report provides a benchmark against which our collective progress to conserve this essential resource can be measured. The report synthesizes the work of some 200 soil scientists from 60 countries. It provides a global perspective on the current state of the soil, its role in providing ecosystem services, and the threats to its continued contribution to these services. The specific threats considered in the report are soil erosion, compaction, acidification, contamination, sealing, salinization, waterlogging, nutrient imbalance (e.g. both nutrient deficiency and nutrient excess), and losses of soil organic carbon (SOC) and of biodiversity.
