Climate-smart agriculture (CSA) challenges to create zero hunger world through sustainably increasing agricultural productivity and income, reducing greenhouse gas emission, and building resilience to climate change. This paper documents the existing CSA practices adopted by farmers in Jaintapur upazila of Sylhet district. Data were collected through personal interview as well as focus group discussion from 102 randomly selected farmers from three unions of Jaintapur upazila during July to December 2017. We identified nineteen CSA practices that were practiced by the farmers in the study area. Those practices were perching, high yielding varieties, adjusting planting time, farm yard manure, green manuring, crop rotation, vermicomposting, cover crop, fallowing, rain water harvesting, AWD, improved livestock breed, community seed bed, USG, IPM, sorjon method, floating bed fodder, zero tillage and raised bed planting which were categorized into six pools. Finally, we proposed a three-tier up-scaling approach for the dissemination of fifteen potential CSA practices as short, medium and long term strategy for the study site which would be also applicable for other areas of Sylhet region.
