Welcome to part 2 of our mini series promoting the UN #WorldSoilDay on 5th December 2021 to raise awareness of salt-affected soils. In this piece we look at; economical losses, migration, and the worldwide land area affected by soil salinization. This is part of our series on Growing Sustainably.

In part 1 of this mini series we looked at Salt-Affected Soils: A Global Concern Reducing Agricultural Productivity. This time we’re taking a look at the effects of soil salinization.
Economical Losses from Soil Salinization
The global annual cost of salt-induced land degradation in irrigated areas is estimated to be $27.3 billion USD related to lost crop production.

Migration from Soil Salinization
As climate change and water scarcity increase, more soils become salt-affected, forcing people to leave their once productive land and migrate.

Worldwide Land Area Affected by Salinity
Do you know that 8.7% of the total land area worldwide is affected by salinity?
The global map on salt-affected Soils contains contributions from over 118 countries with 257,419 locations containing measured soil data.
