December 5th is World Soil Day. This day is to remind us how important healthy soil is in connection with “the good life”. Soil is the basis for our food. Biovision is committed to promoting healthy soils and has always called for the recognition of agroecology as a central approach to combating hunger.

Healthy soil has high biodiversity and can regenerate itself. A humus layer populated by different organisms and a soil traversed by roots stores water well and protects the ground from catastrophes such as landslides. And that's not all: healthy and sustainably managed soil also helps to curb climate change because it keeps CO2 where it belongs: in the soil.
Agroecology supports healthy soil
Healthy soil keeps organisms in balance because high biodiversity makes it more difficult for a single species to reproduce unchecked. Fewer pests reduce the use of pesticides drastically, and a natural, nutrient-rich soil needs less fertilizer. Agroecological methods make the use of synthetic pesticides and fertilizers virtually obsolete, helping the climate because the production and application of synthetic chemicals releases many climate-damaging emissions. We currently have too much carbon dioxide (CO2) in the air and too little carbon in the earth. Humus stores carbon, one of its main components, in the earth where it belongs. Conventional agriculture not only emits too much CO2, but has already damaged around a quarter of the world's soils. Furthermore, diversified production, as promoted by the holistic approach of agroecology, helps to reduce the particularly high stresses on the soil that result from current conventional agricultural methods.
In addition to ecological dimensions, agroecology also includes economic and social principles that increase resilience, especially resilience of people and soils in the face of climate change.
