The problem

Healthy, fertile soils provide the basis for all life from nutrient cycling, purifying water, and growing plants.

Soil is renewable, but is also highly sensitive to over use and degradation as a result of industrial agriculture, pollution, fertilisers, and development.

Soil erosion is a major issue, with many areas suffering losses that put the future of agriculture at risk.

Loss of soil biodiversity as a result of the use of chemicals and fertilisers reduces the ability of soils to absorb essential nutrients (including carbon) and create micro-biomes that support higher plants (including trees).

Soil compaction in urban and rural areas can exacerbate flooding issues as soils do not absorb rainfall and instead water flows overland to flood places where people live.

How nature solves the problem

Natural vegetation mitigates issues including soil erosion.

Reducing/eliminating fertilisers and chemicals means that soils can rejuvenate so it can provide the functions to absorb carbon and other nutrients.

Biodiverse soils containing a large number of worms and insects can help to breakdown and recycle wastes in a more cost effective way than many municipal systems.
