The smallholder farmers living in the Bengal Delta around Khulna, Bangladesh are extremely vulnerable to recurrent hydroclimatic variability. They confront serious harms from recurrent hydroclimatic extreme events like a cyclone, storm surge, tidal flooding and salinity intrusion, etc. These events severely affect agricultural income, livelihood, and food security of, especially poor and marginal farming communities. Climate information services (CIS) can potentially help these farmers to manage hydroclimatic risks through informed decisions. This study aims to explore farmers’ current practices, information needs, and co-production of CIS with farmers. Finally, we study willingness to pay (WTP) for CIS of smallholders for wider application and CIS sustainability. This study confirms that co-production of CIS through capacity building and frequent interaction with farmers and local extension officers has better accessibility and uptake of climate information in agricultural decision-making and disaster risk reduction of smallholders in the Bengal Delta.
