Pit stop of the cross-sectoral programme “NCCS-Impacts”: preliminary results, lessons learnt and the way forward

The currently running “NCCS-Impacts” programme of the Swiss National Centre for Climate Services (NCCS) is dedicated to the analysis of selected cross-sectoral climatic impacts under future climate change in Switzerland. Previous work within the NCCS network such as the climate change scenarios CH2018 and hydrological scenarios Hydro-CH2018 serve as central pillars to carry out projects on the following aspects: (1) socioeconomic scenarios, (2) human and animal health, (3) ecosystem services, (4) supply chains, and (5) economic costs. The different projects are inter-linked with each other, share manifold synergies and jointly elaborate the two cross-cutting themes ‘social justice’ and ‘extreme events’.In addition to the generation of new science-based insights on climatic impacts in Switzerland and their central challenges for the environment, economy and society, NCCS-Impacts also has a clear focus on the development and provision of actionable products for decision-makers in the field of climate adaptation and mitigation. To this end, the work in the five different projects follow a co-production approach with consortia composed of 17 partners from research and practice. The projects run from 2023 until 2025. 2026 will be devoted to a programme-wide synthesis.Serving as a pit stop of the programme, this presentation will cover the main achievements reached so far. This includes intermediate results regarding the newly elaborated Swiss Socioeconomic Pathways (SSP-CH) and future projections on heat mortality and heat vulnerability aspects. The presentation will also reflect on experiences and lessons learnt made in terms of governance of the programme and provide a framework on how the project results are consolidated into the joint programme synthesis.
