Integrated Climate Adaptation Solutions for the Hindu Kush Himalaya (HI-CAS)-Nepal

The Integrated Climate Adaptation Solutions for the Hindu Kush Himalaya Region (HI-CAS) is a regional project implemented in Bangladesh, Bhutan, and Nepal funded by Global Affairs Canada (GAC) and implemented by the International Centre for Integrated Mountain Development (ICIMOD) in partnership with the Centre for Environmental and Agricultural Policy Research, Extension and Development (CEAPRED) in Nepal.  The project aims to improve climate-resilient, nature-positive livelihoods while strengthening the leadership and agency of rural women and Indigenous Peoples and Local Communities (IPLCs). The project will deliver locally tailored climate adaptation solutions grounded in feminist and human rights-based methodologies thus ensuring an inclusive approach that place the rights, agency, and leadership of IPLCs at the centre. These evidence-informed Integrated Adaptation Solution Packages (IASPs) will combine springshed management, renewable energy technologies for power irrigation systems, and agrobiodiversity practices. They will be complemented by capacity building and knowledge sharing to drive institutional policy and action and to attract sustainable investments in climate action and development, particularly in the water, energy, and agrobiodiversity sectors, with a strong focus on the leadership of women and IPLCs.

Description of the activities: 

These activities will be implemented in Ward 1 and 2 of Roshi Rural Municipality, Kavrepalanchowk District, and Ward 8 of Dhankuta Municipality, Dhankuta District, Nepal. Core activities focus on springshed management through nature-based interventions such as contour trenches, toe trenches and live check dams designed according to slope gradient. Solar powered irrigation system will be established, one in each site, utilizing spring water from Walung dhara (Dhankuta) and Andehri Khola (Roshi). In addition, seven small-scale gravity flow irrigation schemes will be constructed or rehabilitated. Agrobiodiversity interventions will encompass the establishment of nutritional gardens and community seed banks, promotion of local and indigenous crop species where feasible and construction of soil-cement rainwater storage tanks (dimension - 2 m × 2 m × 1 m), where required.

Description of the structures: 

The proposed project components include the construction of a solar lift irrigation system and gravity fed irrigation at both project sites. 

Solar lift irrigation systems

  • In Dhankuta, the key physical works include a 117 m² solar array, 3 m² control system building, 50 m3 intake reservoir, 50 m3 distribution reservoir, 472 m of transmission pipeline, and 692 m of distribution pipeline.
  • In Roshi, the key physical works include a 140 m² solar array, a 35 m² control system building, 75 m3 intake reservoir, 75 m3 distribution reservoir, 252 m of transmission pipeline, and 588 m of distribution pipeline.

Gravity flow irrigation schemes in Roshi Rural Municipality

  • In Kamero Kholsa, construction of 2 intake structures of 0.41 m3 each, maintenance of existing transmission pipeline of 200 m.
  • In Dur Kholsa, construction of intake structure of 0.41 m3, 210 m of transmission pipeline.
  • In Bhate Kholsa, construction of intake structure of 0.41 m3, reservoir of 20 m3, 369.3 m of transmission pipeline, 686 m of distribution pipeline.
  • In Thami Kholsa, construction of intake structure of 0.41 m3, reservoir of 20 m3, 567 m of transmission pipeline, 600 m of distribution pipeline.

 Gravity flow irrigation schemes in Dhankuta Municipality

  • In Lampate, construction of intake structure of 0.41 m3, 271.7 m of transmission pipeline, 233.2 m of distribution pipeline.
  • In Siboleni, construction of intake structure of 0.41 m3, reservoir of 4 m3, 1260 m of transmission pipeline.
  • In Tamungdang Hulake, construction of 2 intake structure of 0.41 m3 each, 1211 m of transmission pipeline.

Description of the environment / site characterization]

The project sites are located within the sub-tropical region of Nepal and are characterized by moderate to steep terrain, forested spring sheds, agricultural terraces and dispersed rural settlements. Two major rivers, Tamor in Dhankuta and Roshi in Roshi flow through the downhill areas. In both areas, springs are the primary source of water for drinking and agriculture purposes. The areas are predominantly inhabited by indigenous communities (Tamang in Roshi and Rai communities in Dhankuta) whose livelihood is largely dependent on agriculture. However, people are facing the problem of declining spring discharge, seasonal water scarcity, erratic rainfall, landslides, floods, and land degradation.
