About this project
This project proposes the construction of a solar-powered submersible pump irrigation system to explore a more steady water source to be distributed to the rice field. Combining with solar or sun as main energy source for the technology, it allows us to introduce to wider farmer community of sustainable practices that can be incorporated and will lower operational cost. Solar panels will be installed attached to the borehole pump and can last for 20 years
With the proposed budget, this project will allow farmers to have one additional harvest season per year which will be projected to increase their income by IDR 200 million additional collective income annually for 25 farmers. The project also includes training and engagement of stakeholders in local, state, and provincial level. In summary, this program will double productivity of 25 Ha of land, provide additional income for at least 25 farmers, empowering 10 village leaders (youth, land owner, farmer community, farmer’s wife, village board etc as local heroes/ambassador that will represent the community in monitoring the project and maintaining the technology.
This program will be implemented for approximately 4-5 months starting from preparation and initial stakeholder engagement, location survey for submersible pump location, procurement, and implementation of technology and activities.
Analysis shows the project generates a first-year ROI of 408%, a 5-year NPV of +Rp 680 million, and a conservative SROI of ≈ 8.
Goals and Objectives
The village of Luwus, Tabanan, Bali, has been experiencing a water irrigation crisis since 2020 The community in this village depends on the subak (local cooperative water management system) irrigation to plant crops, which now has stopped flowing not long after the main water supply was diverted for domestic use. This has left 25 hectares of farmland unusable during the dry season. Farmers can only plant once a year instead of twice and losing up to 8 CAD per season in potential income which also equals to 150 tons of rice produce.
Main goals of this project would be to revitalize 25 Ha unproductive land during dry seasons, provide cost-effective and environmentally friendly irrigation system, increasing farmers income by at least in CAD Rp 4 million/person/year, and preparing human resources through inclusive training and participatory decision making process which will enhance sense of belonging towards the project and to build trust within the community itself
Our approach in engaging beneficiaries through training and technology construction will be done from the beginning, allowing them to make partial decisions regarding the project and therefore develop a sense of ownership towards the project. After the implementation period is finished, we have budgeted a small amount of maintenance cost that can be used by the local hero/ambassador to replace certain components that might need replacement.
Although the scale up of the project is predicted to be more in the direction of spreading awareness regarding good practices such as rotation crops and how it could save water and benefit the nutrient content in the soil, the possibilities of replication in other areas is high. Especially with rocketing water demand in south Bali, water sources in the north, and central part of Bali will most likely be affected either mildly or severely.
Expected result
This project is expected to generate significant impacts on the community, the environment, and the overall sustainability of the program. The anticipated outcomes include an improvement in knowledge and skills, particularly in the application of innovative solutions that support economic, social, and environmental aspects. Through the implementation of this initiative, communities are expected to gain direct benefits such as enhanced welfare, improved health, and increased awareness of the importance of sustainable resource management.
Furthermore, the project aims to establish a collaborative ecosystem that involves multiple stakeholders, including local communities, academia, the private sector, and government institutions. Such collaboration is expected to strengthen the long-term sustainability of the program by promoting energy efficiency, reducing emissions, and creating added economic value from available resources.
In essence, the expected results are not limited to short-term outputs but are also designed to generate lasting impacts that can be replicated and scaled in other regions. Thus, the project contributes meaningfully to advancing sustainable development goals while addressing existing social and environmental challenges.
