Sustainability of Solar-Powered Pump Irrigation System (SPIS) As an Alternative Irrigation Method

This study determines the sustainability of the Solar-Powered Pump Irrigation System (SPIS) as an alternative irrigation method, describes its implementation in Juban, Sorsogon, assesses its role in improving rice productivity, gathers farmer feedback, and proposes relevant policy outputs based on the findings. A descriptive qualitative research design was used to examine farmer experiences and system performance across two SPIS project phases. Data were collected through documentary material from NIA and interviews involving twelve purposively selected farmer-beneficiaries. Results indicated that SPIS supported more consistent water access, increased rice yield for several farmers, and enabled all respondents to plant twice annually. Many also reported higher net returns due to reduced fuel and labor costs. Despite these gains, challenges such as pump malfunctions, limited canal reach, and solar dependency during cloudy weather affected system efficiency. Farmers perceived SPIS as cost-saving, environmentally friendly, and generally easy to operate, but noted the need for better infrastructure and maintenance support. Based on the findings, the study developed a policy brief that recommended improvements in site assessment, infrastructure upgrades, technical services, and farmer capacity-building. Overall, SPIS demonstrates strong potential for sustainable, climate-resilient rice farming when paired with localized policy interventions and ongoing institutional support.
