Figure 5.10 | Synthesis of literature on the implementation of on-farm adaptation options across different cropping systems. Adaptation options that have been implemented by growers are considered ‘tested’, while those that have not are considered ‘untested’. Untested options are those that appear in studies as suggestions by stakeholder or experts but were not implemented within the study. The assessment draws on >200 articles published since AR5. The confidence is based on the evidence given in individual articles and on the number of articles. See SM5.2 for details.
