CTA Project Completion Report: Accelerating the Uptake of Climate-smart Agriculture in ACP countries (UPCSA)
Published 2020“…However, the science of delivery of CSA (actual field level adoption by farmers) has been far lower than the science of discovery (potential impact and technical advancement on CSA), as the mass adoption of these potentially game-changing climate-smart agricultural approaches is not happening at the expected rate. One of the reasons for this is because successful upscaling of these innovations does not depend exclusively on the technical characteristics of the practices, but also on enabling policy and institutional environment; i.e. favourable policies, institutional capacities, and user feedback to continuously refine the CSA. …”
