Understanding carbon sequestration from nature-based solutions

Abstract

The International Union for the Conservation of Nature (IUCN) defines nature-based solutions (NBS) as “actions to protect, sustainably manage, and restore natural or modified ecosystems that address societal challenges effectively and adaptively, simultaneously providing human well-being and biodiversity benefits”. We assessed evidence for the greenhouse gas (GHG) mitigation potential of four nature-based solutions in Scotland (agroforestry, hedgerows, un-cultivated riparian buffer zones and the restoration of species-rich grasslands) and how these can help mitigate the impacts of climate change and reduce biodiversity loss. In addition, we provided a synthesis of the strength of evidence for including these as part of Net Zero policy objectives and carbon codes.
