Current activities

Stephen Hallett haslong-standing expertise in the application of spatial decision-support systems, big data, GIS, remote sensing and informatics in environmental science, with particular reference to soil resource systems and the natural environment. His work involves modelling geohazards and the application of spatial, policy-oriented environmental decision-support systems. Stephen's research interests include agri-informatics; soil and land resource management; geohazards and urban infrastructure; and environmental risk mitigation and climate change impacts.He has worked on a wide range of public and private-sector projects in the UK and internationally.

Stephen was recently appointed one of NERC’s ‘Digital Environment Champions’, a role overseeing the ‘Constructing the Digital Environment’ Strategic Priorities Fund programme led by NERC, and supported by EPSRC and Defra.

Stephen is Director and Centre Champion of the NERC/ESRC 'DREAM' Centre for Doctoral Training in big data and environmental risk ( He is also the Cranfield manager and point of contact for the NERC 'CENTA2' Doctoral Training Partnership (

Stephen has a responsibility for Cranfield's national Land Information System (LandIS) [Defra SP1608], containing comprehensive soil and related near-earth environmental information for England and Wales (

Stephen sits on the governing board of the Data & Analytics Facility for National Infrastructure (DAFNI) ( within the UK Collaboratorium for Research on Infrastructure & Cities (UKCRIC).

Stephen is a Senior Fellow of the Higher Education Academy (SFHEA) founding the Cranfield 'Environmental Data Science' MSc, he teaches on the Cranfield MSc in ‘Geographical Information Management’ (GIM). He is the author of a wide range of academic papers and reports and supervises several doctoral studies ranging from infrastructure geohazard modelling to geo-biophysical land systems degradation.

Selected research projects across UK and EU funding agencies include: ‘CINITDIEN - Championing INnovation In The DIgital ENvironment’ [NE/S016287/1]; GCRF ‘Tackling precision nutrient management in developing countries using geospatial and in-field technology: Case study Kenya’; European Commission Joint Research Centre project ‘Collection of soil data in SOTER format from 14 Danube strategy countries, at scale 1:250 000’ [JRC/IPR/2017/D.3/0002/OC]; Satellites for Food Precision Soil Mapping [NERC NE/P008860/1]; FOWARIM (Fostering Water-Agriculture Research and Innovation in Malta) [H2020-TWINN-2 (692162)]; Optimising Big Data to Drive Sustainable Agricultural Intensification - Soil-for-Life [BBSRC BB/M011860/1]; Enhancing nutrient use efficiency from biosolids for a resilient crop production system [NERC NE/M012794/1]; Community Response to Extreme Weather Events (CREW) [EPSRC EP/F036795/1]; Development of a Horticultural Soil Management Information System (SMIS) [AHDB CP107d/3110107425]; Infrastructure Transitions Research Consortium [EPSRC EP/I01344X/1]; Irish Soil Information System [European Environmental Protection Agency STRIVE 2007-S-CD-S1]; Ecosystem Services Databank and Visualisation for Terrestrial Informatics [NERC NE/L012774/1]; Farming Truth [European Space Agency ESTEC A0/1- 6124/09/NL/US].

Stephen also runs Soil-Net ( - an environmental educational resource for school students and teachers, serving soils information to over a million users worldwide. He also leads Cranfield's 'World Soil Survey Archive and Catalogue' project (WOSSAC) ( - a unique global environmental archive pertaining to soils and soil resources. WOSSAC was instrumental in Cranfield being awarded the 2017 Queens Anniversary Award for Soil Science.
