OpenCLIM
The OpenCLIM project (Open Climate Impacts Modelling Framework) is designed to support UK assessment of climate risks and adaptation, including future Climate Change Risk Assessments and National Adaptation Programmes, by developing and applying an integrated impact assessment model.
Updated on December 10 2025
OpenCLIM (Open CLimate Impacts Modelling framework) is an integrated assessment framework that brings together existing models for highlighting the impacts of climate change and informing adaptation needs at national and place-based scales.
In its current form, the implications of climate change on agriculture, biodiversity, heat stress, flooding, drought and water supply are considered. It includes changes to urban building density and type, land surface material and biodiversity enhancement. Driving these future changes across these different sectors are the latest UK Shared Socioeconomic Pathways (SSPs) and UK climate scenarios.
The project is hosted by the Tyndall Centre at the University of East Anglia and Professor Robert Nicholls is the Principal Investigator. DAFNI is one of the project partners.

The role of DAFNI in the OpenCLIM project was first presented at the Roadshow with OpenCLIM partners in September 2020. The presentations are available below and a webinar was held in February 2024, which is available here.
