Soil is so incredibly important for food security and essential ecosystem functions and so the United Nations General Assembly declared 2015 the International Year of Soils. The aim of this declaration is to increase awareness about and gain international support for the world's soil.
Globally only 15% of land is suitable for growing crops. Maintaining healthy soil on this land is essential if we are to feed an ever-increasing global population. Currently around a third of all soils in the world is degraded. Worse still, 75% of this degradation is severe.
