This study evaluates the suitability of wetlands in Jember Regency for cultivating the flood-tolerant 'Lusi' glutinous rice variety, aimed at enhancing food security amidst climate change-induced flooding. Using Geographical Information Systems (GIS) and spatial analysis, this research identifies land suitability classes and key limiting factors affecting the productivity of 'Lusi' rice. It addresses a critical knowledge gap on the adaptive potential of flood-tolerant rice varieties in wetland ecosystems, a topic that remains underexplored in Indonesia. The hypothesis posits that targeted interventions, such as soil pH adjustment and drainage enhancement, can optimize these wetlands for sustainable agriculture. The results indicate that 65.21% of the wetlands are moderately suitable (S2) but limited by suboptimal pH and drainage, while 24.64% are marginally suitable (S3) due to significant flooding and poor drainage. Approximately 9.25% are currently unsuitable (N) for cultivation. For the first time, this study offers a detailed spatial assessment of land suitability for 'Lusi' rice, providing novel insights into optimizing wetland use for climate-resilient agriculture. The scientific contribution lies in applying GIS-based mapping to assess the suitability of specific rice varieties under evolving climate conditions, thus opening new avenues for adaptive agricultural practices in flood-prone areas.
