Unsustainable use of land around the world is threatening to degrade millions of hectares of natural land, nearly the size of Brazil, according to a new United Nations report.

The report by the UN Environment Programme (UNEP) titled “Assessing Global Land Use: Balancing Consumption with Sustainable Supply” was produced by the International Resource Panel.

The panel is a consortium of 27 internationally renowned resource scientists, 33 national Governments and other groups, hosted by UNEP.

To find out more about the report, Leda Letra spoke to UNEP's  Executive Director, Achim Steiner, on the line to Davos, Switzerland, where he is attending the World Economic Forum.
