Soil Maps

2015 is the United Nations International Year of Soils

The 68th UN General Assembly declared 2015 the International Year of Soils (IYS 2015).  In honor of this, here are two soil maps from the Williams & Heintz Map Vault.

Why International Year of Soils?

Soils are a finite natural resource and are nonrenewable on a human time scale.  Soils are the foundation for food, animal feed, fuel and natural fiber production, the supply of clean water, nutrient cycling and a range of ecosystem functions.  The area of fertile soils covering the world’s surface is limited and increasingly subject to degradation, poor management and loss to urbanization.  Increased awareness of the life-supporting functions of soil is called for if this trend is to be reversed and so enable the levels of food production necessary to meet the demands of population levels predicted for 2050.  Soil Science Society of America

You can find interactive, digital soil maps on line at GlobalSoilMap.net and at the USDA’s Web Soil Survey.

The FAO/UNESCO Soil Map of the World  has published soil maps of continents and large regions at 1:5 000 000 scale. They would look great as print maps! 😉
