Areas of expertise

  • Computing, Simulation & Modelling
  • Natural Capital
  • Sustainable Land Systems
  • Water Science and Engineering


Professor Holman joined Cranfield University in 1994, working at the northern regional office of the Soil Survey and Land Research Centre, formerly the Soil Survey of England and Wales, where he contributed to the development of groundwater quality protection strategies in Lithuania and the Philippines and soil mapping of the Isle of Man.

Professor Holman brings interdisciplinary hydrogeological, spatial pedology and agricultural expertise to sustainable land and water resource management and climate change impacts and adaptation research in the UK, Europe and internationally for a range of Governmental, non-governmental and commercial organisations.

He was the founding Co-Chairman of the International Association of Hydrogeologists' Commission on Climate Change and Groundwater (2003-11).

Current activities

Professor Holman leads the Catchment Management Community of Practice within the Cranfield Water Science Institute.  His research over the past 25 years has focussed on understanding and modelling how changes in current and future land use and land management at catchment to national scales affect natural capital and ecosystem services, including water regulation, water purification and food production.   He is the Cranfield Principal Investigator (PI) on a number of recent major projects relating to water and land resources, leading the:

    Development of the D-Risk online tools to support improved drought risk assessment within UK irrigated agriculture (NE/S013997/1; NE/N017471/1)

    Modelling of post-Brexit trade scenarios and future agricultural support policy on Welsh farming (ERRAMP)

    Agricultural research within two of the projects in the NERC Droughts and Water Scarcity programme (NE/L010186/1; NE/L010070/1)

    Water resources systems modelling within the NERC and Indian Ministry of Earth Sciences-funded project on "Sustaining Himalayan Water Resources in a Changing Climate " (NE/L010070/1)

    Development of an interactive web-based Integrated Assessment Platform (IAP) for the assessment of climate change impacts, adaptation and vulnerability within natural resource systems (water, agriculture, forest and biodiversity) across Europe (FP7 Contract No 244031 and 312848)


Recent clients have included:

  • Research Councils (NERC, BBSRC and EPSRC)
  • UK Government departments, including Defra and DFID
  • Welsh Government
  • European Commission (FP7 and DG Environment)
  • Environment Agency
  • Broads Authority
  • Royal Society for the Protection of Birds.
