Abstract

Disruptions to irrigation systems are among the key factors affecting farming sustainability by influencing water availability and farmers' cultivation decisions. This study aimed to analyze the impacts of disruptions to the Dam Klerek Irrigation System on farming activities, identify farmers' adaptation strategies, examine the factors influencing these strategies, and investigate the role of agricultural extension workers in supporting farming sustainability in Lumajang Regency, Indonesia. A descriptive qualitative approach was conducted in Gesang, Pulo, and Jatisari Villages, Tempeh District. The informants consisted of farmers, agricultural extension workers, and the coordinator of the Agricultural Extension Center (BPP), selected through purposive sampling. Data were collected through observations, in-depth interviews, and documentation, then analyzed using the Miles, Huberman, and Saldaña interactive model. The findings showed that irrigation system disruptions reduced the reliability of water distribution, affecting farming activities. In response, farmers modified cropping patterns, selected crops suited to water availability, adjusted planting schedules, and optimized available water resources. These strategies were influenced by water availability, economic considerations, farming experience, institutional support, and irrigation infrastructure conditions. Agricultural extension workers acted as facilitators, advisors, and intermediaries in strengthening farmers' adaptive capacity. This study concludes that sustaining farming systems under irrigation disruptions requires synergy among irrigation infrastructure rehabilitation, institutional strengthening, and agricultural extension services to enhance farmers' adaptive capacity.
