Who we are

The GSNI is part of the Department for the Economy Northern Ireland (DfE). It is staffed by scientists of the British Geological Survey (BGS) under contract to DfE, which allows GSNI to call upon expertise from within other parts of the BGS. GSNI also advises other Northern Ireland government departments and liaises closely with the Geological Survey of Ireland (GSI).

Science Strategy and Stakeholder Workshop

GSNI is developing a science strategy which, subject to approval, aims to address particular challenges and opportunities for Northern Ireland.

An inclusive and holistic science strategy would enable GSNI to augment, adapt, focus and design its work programme and scope to benefit each citizen living in Northern Ireland. As part of our listening process, GSNI is carrying out a range of engagement activities to help steer and inform the content of the new Science Strategy. So we invite you to...

  1. Take our 8-minute survey by 10 February to help inform future decisions
  2. Share the survey link with your contacts and stakeholders to optimise the openness and accessibility of our survey.
  3. Register your interest in attending our stakeholder workshop which will explore key themes on the morning of 20 February by emailing gsni@economy-ni.gov.uk
  4. Book your free place at GSNI's Northern Ireland Science Festival public event featuring a series of nano-talks, hands-on activities, displays and mini-workshops - Geoscience Going Forward - Come Shape your Future
