Healthy soil provides the largest store of terrestrial carbon. When managed sustainably. soil can play an important role in climate change mitigation by storing carbon (carbon sequestration) and decreasing greenhouse gas emissions in the atmosphere.
Conversely. if soil is managed poorly or cultivated through unsustainable agricultural practices. soil carbon can be released into the atmosphere in the form of carbon dioxide (CO2). which can contribute to climate change.
By restoring degraded soils and adopting soil conservation practices. there is a major potential to decrease the emission of greenhouse gases from agriculture. enhance carbon sequestration and build resilience to climate change.
Key challenges
As reported by Agriculture Organization of the United Nations (FAO)`>.FAO. climate change represents a serious threat to global food security. not least because of its effects on soils. Changes in temperature and rainfall patterns can have a great impact on the organic matter and processes that take place in our soils. as well as the plants and crops that grow from them.
To meet the related challenges of global food security and climate change. agriculture and land management practices must undergo fundamental transformations.
FAO calls on its member countries to adopt improved agriculture and soil management practices that increase soil organic carbon. such as agro-ecology. organic farming. conservation agriculture and agroforestry. These practices produce fertile soil rich in organic matter (carbon) and less susceptible to erosion and desertification. and will maintain vital ecosystem services such as the hydrological and nutrient cycles. which are essential to maintaining and increasing food production.
As it is underlined in this year’s theme of World Soil Day. erosion as the greatest threat for soil quality. decreases soil’s capacity to mitigate the risks and effects of climate change. Agriculture Organization of the United Nations (FAO)`>.FAO calls people and stakeholders all around the world to take action to Stop Soil Erosion to Save Our Future.
