Purpose: Identifies a hierarchy of information and argues that professional knowledge has marginalized ‘local knowledge’.
Methodology/Approach: In a review of recent research, the paper offers examples of how ‘wicked problems’ (from obesity to climate change) impose different burdens on different communities, which foregrounds the value of residents’ experiences.
Findings: In an era of climate change, adaptive planning must incorporate ‘local knowledge’, which may return to older technologies and established practices.
Research Implication: The paper argues that ‘local knowledge’ can be ‘powerful knowledge’, as discussed within educational research, which has important implications for school and college curricula.
Originality/Value of paper: Amateur experts, citizen observatories and crowd sourced data can all play significant roles within communities facing new forms of risk and hazard.
