Abstract

Nepal is rich in fresh water with more than 6,000 rivers, including that originated from the Himalaya. Being rich in water resources, it has the potential of producing more than 83,000 MW of energy. However, currently Nepal has only harnessed 1.2 % of its capacity. Besides, a Kulekhani (60 MW) all other hydropower plants in Nepal are of run of river type. Such plants are being exclusively used for producing electricity and undermining its potential of multiple use. We developed a prototype to demonstrate the multiple use of water resources. Our research methodology was based on extensive literature review and expert consultations. We found that Nepal has the potential for using hydropower plants in multiple ways. Its dam can be used for recreational activities, such as boating and swimming, and income generation activities like fish farming. Likewise, the most important secondary use of hydropower plant is irrigation. Although, Nepal has agricultural-based economy almost 70% agricultural lands are unirrigated. Hence, water from hydropower can be used for irrigation that increases agriculture production and productivity, contributing to food security. Likewise, the water can also be transferred to villages and cities for drinking purpose. The produced electricity can be used for modernizing agriculture practice. For instance, use of infrared red and blue lights inside the greenhouse to increase the production by increasing rate of photosynthesis. Hence, the multiple use of hydropower will contribute to local and national economy. In addition, it contributes to Goal 1 (No poverty), 2 (Zero hunger), and 7 (Affordable and clean energy) of Sustainable Development Goal (SDG). We suggest that policymakers and government of Nepal should implement this prototype for optimum use of water resource in Nepal.
