Around 95% of the food we eat grows in the earth. However, more than one-third of the world’s soils are degraded; without rapid action, this figure could rise to 90% by 2050. Soil erosion decreases the water, nutrients and root-space available to plants. Healthy roots enable better use of nutrients and water.
South African farmers have a long history of resilience and survival when they maintain control over their land, operations, production decisions, and market access.
CO2 & plant biomass allocation patterns -Plant biomass allocation refers to the way in which plants distribute their resources, such as carbon and nutrients, between different organs. Elevated levels of atmospheric CO2 have been shown to impact plant biomass allocation, which in turn can affect ecosystem dynamics and carbon sequestration.
