14. All states shall support improvements of soil health for resilient food production and carbon sequestration

Rapporteur: Joanna Santa Barbara

This plank is directed at two of the six items on the Platform for Global Survival — Global Warming and Famine. It is also relevant to another major threat to human survival — the biodiversity crisis.

Definitions

Soil health

A widely used definition is that of the US Department of Agriculture: the continued capacity of soil to function as a vital living ecosystem that sustains plants, animals, and humans.

Soil is composed of inorganic matter (ground up rock), organic matter (living and dead plants, animals, bacteria, protozoans, actinomycetes and fungi), air and water. Soil health depends on complex interactions between these components. These determine the physical structure of the soil, its chemical composition and its nutrient levels, all of which affect the capacity of the soil to sustain life of plants, animals and humans. In general, the higher the organic component of a soil (generally about 5%), the more life it can sustain. This component is variously referred to as ‘soil organic matter (SOM)’ or ‘soil organic carbon (SOC)’, as it comprises carbon-rich compounds.

We need healthy soils to eradicate hunger, mitigate and adapt to the climate crisis, reduce poverty, provide clean water, restore biodiversity, reduce pollution, provide livelihoods and reduce the harm from extreme weather.
