2. Background and reasoning for the projectMolecular Metrics for Assessing the Status of Peatlands
Background
Peatlands are vital to many
ecosystem services
80% of UK peatlands are damaged
2020 Million Hectare
Challenge/Peatland CodeRestoration: rewetting 
vegetation reappearance  C sink
Is our restoration efforts are
working?

12. NERC Soil KE Fellowship emphasis, Data and Apps
OUTCOME - IMPACT
NERC digital platforms become the defacto tools for the
dissemination of NERC soil science data and crowdsourcing of soil
data for industry, society and other stakeholders, in the UK,
Europe and potentially beyond, raising the public awareness of
soils.
