Climate SMART Agriculture Irrigation Channel Construction
Climate SMART Agriculture Irrigation Channel Construction
The Climate Smart Agriculture Irrigation Channel at Khameythang is a strategic infrastructure initiative under the Bhutan for Life Program, aimed at improving agricultural productivity, enhancing climate resilience, and securing sustainable livelihoods. The project spans approximately 1.4 km and is designed to supply irrigation to 253.5 acres of wetland, directly benefiting 87 households (67 male-headed and 20 female-headed).
Project Objectives:
Enhance agricultural productivity by ensuring consistent and adequate water supply.
Improve climate resilience of farmlands against erratic rainfall patterns and flash floods.
Promote climate-smart agriculture practices to optimize resource use and reduce environmental impact.
Strengthen rural livelihoods by increasing crop yields and improving food security.
The project was initiated by the Department of Agriculture under the Ministry of Agriculture and Livestock with technical support from the Irrigation Division, Department of Infrastructure Development with a total fund of Nu. 32.15 million from Bhutan for Life.
Addressing Challenges
For decades, Khameythang farmers have struggled with seasonal water shortages. During the monsoon, temporary water sources were often washed away by flash floods, leaving large portions of fertile paddy fields abandoned. This not only reduced crop yields but also threatened household food security and livelihoods.
Agricultural and Social Impacts
The channel will ensure a steady water supply to 253.5 acres of wetland, significantly boosting rice and vegetable yields and reducing losses caused by drought or inconsistent rainfall. This improved agricultural productivity will directly strengthen household incomes and food self-sufficiency. The project will also ease the labor burden for farmers, especially the 20 female-headed households, by reducing the need for manual irrigation. These benefits extend to improved quality of life, allowing more time for income-generating activities and community participation.
Summary
Environmental and Climate Resilience Benefits
The project incorporates features that promote environmental sustainability and climate resilience. Sedimentation chambers will help manage debris and maintain water quality, while flood control walls will mitigate the impact of flash floods. Controlled irrigation will prevent overwatering, reduce soil erosion, and promote more efficient use of water resources. By aligning with Climate Smart Agriculture principles, the initiative ensures long-term benefits for both the environment and the community.
Sustainability and Future Plans
To ensure the long-term success of the irrigation channel, a Community Water User Group will be established for operation and maintenance. Farmers will receive training in climate-smart agricultural techniques to maximize the benefits of the irrigation system. Continuous monitoring and evaluation will be carried out to track system efficiency, crop productivity, and community satisfaction.
By building both infrastructure and local capacity, the project serves as a sustainable model for future climate-resilient agricultural investments in Bhutan.
