SummaryHealthy soils contain millions of diverse living organisms, ranging from a myriad of invisible microbes, bacteria and fungi to macro-fauna such as earthworms and termites. Soils contain more living organisms in a tablespoon of soil than there are people on Earth with up to 90% of living organisms living or spend part of their lifecycle in soils. Soil is a living resource containing more than 25% of our plant's biodiversity. These diverse organisms interact with one another and with the various plants and animals in the ecosystem, forming a complex web of biological activity.

Maintaining soil biodiversity for good soil health is vital for soil fertility, agricultural production and providing global food security. Soils contain approximately twice the amount of carbon than is currently contained in the atmosphere. Managing soil health can lead to the conservation of soil carbon pools and in some cases increase soil carbon sequestration, which can help offset greenhouse gas emissions and contribute to climate change mitigation. Soil organisms have the ability to break down certain contaminants mitigating against some forms of soil pollution.

It is estimated that only 1% of soil microorganisms species are currently known compared to 80% of plant species. However, growing pressures from increasing global population, erosion and degradation and climate change are threatening soil biodiversity and soil health. In the Soil Ecology and Taxonomy course, we introduce you to soils and soil biodiversity in terms of the major participants involved in key soil processes, functions, fertility and overall soil health. In addition, the course discusses the challenges soils face in relation to degradation, pollution and intensification. The course will explore strategies to improve sustainable soil use to conserve soil biodiversity while maintaining functions and ecosystem services.
