Area of investment and support

Highlight topic funding rounds

The aim of the highlights programme is to support strategic research on a defined subject area.

• Budget: £159 million for rounds one to nine
• Duration: 2015 onwards
• Partners involved: Natural Environment Research Council (NERC)

The scope and what we're doing

A highlight topic focuses strategic research on a defined subject area. The size and duration of projects will be specified for each highlight topic every year.

Opportunities, support and resources available

Highlight Topics update February 2025

In 2024, NERC announced an evaluation of its Highlight Topics scheme, which is now in its 10th year. The evaluation is nearing completion and NERC is now considering the outcomes and appropriate next steps, which we hope to share later this year. As such, we will not run a Highlight Topic ideas call this year, as we develop a simpler and more responsive approach to idea solicitation.

The NERC Big Ideas pipeline remains available as a means of identifying larger scale, including interdisciplinary, challenges that require substantial environmental research to be addressed.

Applications to the 2024 Highlight Topic funding opportunity are currently being assessed and a funding decision is expected in June 2025 .

This webinar was delivered and recorded in early 2022 and does not include information on the most recent investments made through the Highlight Topics scheme.

There have also been a number of personnel changes within NERC and externally, so some contact details provided at the time may now be inaccurate.

If you have any questions regarding the Highlight Topics scheme, we recommend you contact highlighttopics@nerc.ukri.org so your query can be directed to the relevant person.
