YEAR OF SOILS
Healthy soils are critical for global food production and provide a range of environmental services. Healthy soils are the foundation for food, fuel, fibre and even medicine said the United Nations Food and Agriculture Organization (FAO) today as it kicked off 2015 the International Year of Soils on the first-ever World Soil Day.
Soils are also essential to our ecosystems, playing a key role in the carbon cycle, storing and filtering water, and improving resilience to floods and droughts, and yet we are not paying enough attention to this important “silent ally,” the UN agency explained.
The International Year of Soils kicks off today at events in Rome, New York and Santiago de Chile, in an effort to raise awareness and promote more sustainable use of this critical resource.Soil is also the largest pool of organic carbon, which is essential for mitigating and adapting to climate change. In an era of water scarcity, soils are fundamental for its appropriate storage and distribution.
“Today, we have more than 805 million people facing hunger and malnutrition. Population growth will require an approximately increase of 60 per cent in food production,” FAO Director-General José Graziano da Silva warned today.
“Unfortunately, 33 per cent of our global soil resources are under degradation and human pressures on soils are reaching critical limits, reducing and sometimes eliminating essential soil functions,” he added. The UN General Assembly declared 5 December World Soil Dayin December 2013. The Day and Year kicks off today with events in Rome, New York and Santiago de Chile, in an effort to raise awareness and promote more sustainable use of this critical resource.
“I invite all of us to take an active role in promoting the cause of soils during 2015 as it is an important year for paving the road towards a real sustainable development for all and by all,” Mr. Graziano da Silva said.

FAO estimates that a third of all soils are degraded, due to erosion, compaction, soil sealing, salinization, soil organic matter and nutrient depletion, acidification, pollution and other processes caused by unsustainable land management practices.
Unless new approaches are adopted, the global amount of arable and productive land per person will in 2050 be only one-fourth of the level in 1960.
It can take up to 1,000 years to form one centimetre of soil, and with 33 per cent of all global soil resources degraded and human pressures increasing, critical limits are being reached that make stewardship an urgent matter, Mr. Graziano da Silva said.
Calling soils a “nearly forgotten resource,” he urged investment in sustainable soil management, saying that would be cheaper than restoration and “is needed for the achievement of food security and nutrition, climate change adaptation and mitigation and overall sustainable development.”
Echoing that call, UN Secretary-General Ban Ki-moon said that without healthy soils, “life on Earth would be unsustainable.” Indeed, soils are the foundation of agriculture. They provide vital ecosystem services and the basis for food, feed, fuel, fibre and medical products important for human well-being.
“Soil is also the largest pool of organic carbon, which is essential for mitigating and adapting to climate change. In an era of water scarcity, soils are fundamental for its appropriate storage and distribution,” said Mr. Ban, urging all States to pledge to do more to protect this important yet forgotten resource. “A healthy life is not possible without healthy soils,” he declared.
According to FAO, at least a quarter of the world’s biodiversity lives underground, where, for example, the earthworm is a giant alongside tiny organisms such as bacteria and fungi. Such organisms, including plant roots, act as the primary agents driving nutrient cycling and help plants by improving nutrient intake, in turn supporting above-ground biodiversity as well.
