'Triple wins' or 'triple faults'? Analysing policy discourse on climate-smart agriculture (CSA) por Karlsson, Linus, Nightingale, Andrea, Naess, Lars Otto, Thompson, John

“…From this, we identify three important equity issues: First, distributive equity implies a need to acknowledge how CSA may transfer the burden of responsibility for climate change mitigation to marginalized producers and resource managers. Second, a procedural equity perspective reveals how CSA discourses generally fail to confront entrenched power relations that may constrain or block the emergence of more ‘pro-poor’ forms of agricultural development, adaptation to climate change, or carbon sequestration and storage. …”
