The transition from traditional, subsistence based agronomy to commercialized, climate-smart horticulture represents a critical pathway for sustainable rural development and poverty alleviation across South Asia. This research represents a comprehensive synthesis of focusing on in-depth evaluation of six targeted case studies and success stories of farmers at Mirsarai and Sitakunda Upazila, Chattogram, Bangladesh for their socio-economic and agronomic impacts of adopting High-Value Fruits and Crops (HVFC) cultivation. Methodologically, the study employs a mixed methods framework encompassing a reference group (N=6,038), target intervention group (N=361) and a control group (N=72), utilizing participant observation, key informant interviews and structured surveys. The findings indicate a paradigm shift in rural microenterprises, characterized by the accelerated assimilation of climate-resilient practices, including drip and sprinkler irrigation, internet-of-things (IoT) based micro-climate monitoring and integrated pest management (IPM). The integration of Producers’ Marketing Groups (PMGs) effectively eliminated intermediary exploitation, facilitating direct export channels for safe vegetables at a 25% price premium. Ultimately, the RMTP-YPSA framework demonstrates that coupling technological innovation with localized mentorship through Farmer Field Schools (FFS) successfully disrupts cycles of rural vulnerability, offering a scalable blueprint for climate-smart horticultural commercialization and the empowerment of rural youth.
