Soil degradation impact on global food security

Entities: Nature Food · University of California, Irvine · Gloria Mark · Future Self · Institute for Geo‑Hydroinformatics (GHI)

Overview

Recent research published in *Nature Food* quantifies how human‑induced soil degradation affects worldwide crop yields. One study models the effect of erosion, dehydration, compaction and carbon loss across a 10 × 10 km grid and estimates that eliminating just 10 % of degradation could boost the productive capacity of arable land enough to feed roughly 70 million additional people while also storing more carbon and reducing deforestation pressure.

A related analysis by a multinational team from the Technical University of Hamburg examines current losses, finding that damaged soils cause an annual shortfall of about 20 million tonnes of major crops—representing roughly 52 trillion kilocalories, enough to feed approximately 71 million people for a year. The study highlights erosion, compaction and other degradation processes as primary drivers and notes data gaps for salinisation and nutrient imbalances.
