Life on earth depends on healthy soil – and experts hope a new online community hub will inspire policymakers, researchers, farmers, planners and the public to take action to protect this precious but degrading resource.

Soils are essential for food production, biodiversity, clean water and also regulating climate due to their ability to store and capture carbon. However, a third of the world’s soils are degraded due to intensive agriculture, pollution and climate change - resulting in large amounts of carbon dioxide being released into the atmosphere and threatening long-term sustainable food production.

Therefore, uksoils – “a single source for all things soil” – has been launched by a partnership comprising the UK Centre for Ecology & Hydrology (UKCEH), the Sustainable Soils Alliance, Earthwatch, the University of Sheffield, the British Soil Science Society and Scotland's Rural College (SRUC).

Launched ahead of World Soils Day (5 December), the online hub will bring together the best available resources, including educational information and school activities, books and films, data and maps, plus guidance for farmers and land managers on how to support healthy soils. It will also provide a community forum to enable the sharing of knowledge and experiences, encouraging people to link up and carry out initiatives to improve soil health and share locations around the country where soil health pioneers are trying out new technologies and management practices.

The website – uksoils.org – is gradually being developed and will eventually host a series of online events targeted to different topics suggested by its users.

Professor Bridget Emmett, Head of Soils & Land Use at UKCEH, who is leading the initiative, says: “Soils are vital for humans and wildlife but, being hidden beneath our feet, they are often forgotten about and taken for granted. We are here to help change that.

uksoils will bring together information that is scientifically robust and independent to inspire us all to work with others to learn more about soil health and take action to improve it. It is not just the responsibility of governments and those managing our land to safeguard this scarce and non-renewable resource; it is up to all of us in our gardens, farms, woodlands, conservation areas, towns and cities to better understand our soil, care for it, protect it and enjoy it.”

A recent report by the EU’s Mission Board for Soil Health and Food – of which Professor Emmett is a member - identified the need to better link research and innovation with practice and policy to ensure a step change in soil health. It estimates 60-70 per cent of soils in Europe are unhealthy, and has set a target to reverse this, aiming for 75 per cent healthy or improving soils by 2030.

Although the UK is leaving the EU, Professor Emmett says the organisations involved in the hub hope it will encourage national and international collaborations, plus support accessing sources of funding for research and projects. She explains: “Many initiatives are emerging globally that promote the protection of soil health and we believe the UK should become a global leader in evidence-based policy community action to achieve this.”

Professor Emmett provides the voiceover for a new animation, entitled 'Why soil is one of the most amazing things on Earth', which has been produced by the BBC Ideas team in partnership with the Royal Society. To watch the film, visit the BBC website.

Factfile

  • It is estimated there are between 2500-3400 billion tonnes of soil organic carbon down to 1 metre depth - 4 to 8 times larger than the carbon stock in terrestrial vegetation
  • Around 33% of global soils are degraded, resulting in more than 4bn tonnes of global CO2 emissions a year
  • 24bn tons of fertile soil is annually lost from agricultural systems worldwide
  • It takes 100 years for 1cm of topsoil to be produced from bedrock but this can be lost in single rainstorm if no vegetation protects it
  • Soils provide a home to around one quarter of species on Earth
  • There are more microorganisms in one teaspoon of soil than there are people on our planet
