Here are some reasons why we should appreciate the soil beneath our feet

Soil is where it all begins. Few people know that soils are a non-renewable resource. It takes over 1000 years to make 1 cm of soil. This means that in our lifetime, all the soil we see is all there is.

Soils do amazing things for us that we sometimes take for granted. They sustain food production, filter our water, are the source for our medicines and help us to combat and adapt to climate change, according to the U.N. food agency FAO.

The six reasons why the health of the soil is important:

1. Caring for soils = Increased Food security

95% of food is produced in our soils. We can’t hope to feed the growing population and produce the 50% more food we need by 2050 without considering and preserving the quality of our soils. The nutrient content of soils directly influences that of the plants grown within them. Soils exchange nutrients and water with the plant’s roots. The healthier the soil is, the better the crop will be. Soil is a non-renewable resource and its preservation is essential for food security.

2. Caring for soils = Greater biodiversity

Soils host a quarter of our planet’s biodiversity. There are more living organisms in a tablespoon of soil than there are people on Earth. Nowhere in nature are species so densely packed as in soils. Biodiversity is important to the well-being of our planet. It helps species survive and adapt to the changes in nature. Preserving biodiversity means that we are helping keep our planet resilient, adaptive and healthy. Organic farming, rotation grazing, crop rotations and conservation agriculture can preserve the biodiversity found in soils. These methods sustainably increase farm productivity without degrading soil and water resources.

3. Caring for soils = Fewer greenhouse gases

Soils help to combat and adapt to climate change. When managed sustainably, soils can play an important role in mitigating climate change by storing carbon (sequestering carbon) and decreasing greenhouse gas emissions to the atmosphere. Healthy soils with a high organic matter content can also store large amounts of water which help crops cope with drought and adapt to extreme precipitation.

4. Caring for soils = Better livelihoods

Healthy soils can ensure food security, provide better livelihoods and reduce forced migration. Degraded soils means loss of food sources and livelihoods. More than 10 million people have abandoned their homes due to environmental issues including soil erosion, desertification, deforestation and drought. Implementing sustainable soil management strategies that help farmers cope with long-term droughts and soil degradation can help to give people a choice of whether to migrate or stay home.

5. Caring for soils = Cleaner water

Soils are key to a supply of clean water. Soils capture, store and filter water, making it safe to drink. Forests in highland areas not only prevent soil erosion but also ensure good quality drinking water for downstream users. Soils also store water, making it available for crops.

6.Caring for soils = More medicines: 

Soils are important to human health. Most well-known antibiotics originated from soil bacteria, including penicillin.  Did you know that over 500 antibiotics derived from soil microbes!
