Severe land degradation is now affecting 168 countries across the world, according to new research released by the UN Desertification Convention (UNCCD).
The figure, based on submissions from countries to the UN, is a marked increase on the last analysis in the mid-1990s, which estimated 110 states were at risk.
In an economic analysis published last week the Convention also warns land degradation is now costing US$490 billion per year and wiping out an area three times the size of Switzerland on an annual basis. ...

The causes of land degradation are varied, but are widely attributed to drought, climate change, intensive farming practices and poor water management. ...
Efforts to boost agricultural production often lead to deforestation, a major contributor to global greenhouse gas emissions.
This has a knock on effect in terms of reducing the planet's store of natural carbon sinks and destroying the 'ecosystem services' trees provide such as water storage, exacerbating the problem.
