Quantifying and activating the potential of land-based climate change mitigation
This special issue presents research results on land-based climate change mitigation from the Finnish research flagship "Atmosphere and Climate Competence Center" (ACCC). The general aim of the interdisciplinary research flagship is to provide beyond state-of-the-art scientific knowledge on two of the most urgent global grand challenges, climate change and deteriorating air quality, and to co-create knowledge-based solutions to these challenges together with stakeholders. The work is divided into three research programs and this special issue is dedicated to Research Program 1 that is working towards improved estimates and verification of climate impacts of different natural ecosystems and built environments. The studied climate impacts include greenhouse gas balances, albedo effects, aerosol-cloud-climate effects and water cycle effects. It is also studied how climate feedbacks to ecosystems by measuring the ecosystem responses to climate changes and extreme weather events. This work promotes science-based development of carbon farming practices in agriculture and management practices to increase carbon sinks in forests as well as verifies carbon sequestration. The ultimate goal is to simultaneously optimize the value of carbon storage, biodiversity, and yield.
