Shyamnagar & Kaliganj, Satkhira: Overcoming Sundarbans Coastal Soil Salinity with Washed Cocopeat Container Farming
📊 Case Study Technical & Economic Profile
1. Regional Context & Agricultural Challenge
After Cyclones Aila and Amphan, topsoil EC in Shyamnagar and Kaliganj exceeded 8–12 dS/m due to saltwater intrusion, rendering homestead kitchen gardens completely barren during the dry season.
2. Technical Implementation & BARI Protocol Applied
Local women’s groups adopted BARI Chapter 6 Coir Dust technology: washing local coconut husk dust three times to leach out excess sodium/potassium, filling earthen bowls and plastic tubs, and irrigating with harvested monsoon rainwater mixed with BARI Stock A & B.
3. Harvest Results, Economic Impact & Grower Outcome
Families living alongside salty shrimp ghers now harvest fresh mint, coriander, chili, and leafy greens right on their courtyards 12 months a year.
This verified case study from Shyamnagar & Kaliganj, Satkhira demonstrates how adapting BARI Stock Solution A & B and localized soilless structures solves real regional climate and soil constraints while delivering strong commercial returns in Bangladesh.
