Deli Serdang District is among the highest rice producer districts in North Sumatera Province. Unfortunately, climate change and improper cultivation management practices degrade riceland fertility and affect stagnant rice productivity over the years. This study aims to identify the spatial pattern of the limited-factors for riceland suitability and determine land degradation factors and the strategic actions to increase rice production. This study was conducted in 2019 in six districts and interviewed sixty farmers for getting information about riceland degradation issue. The field survey, soil analysis and household-based survey are some methods implemented in this study. The two tools, ArcGIS and SPSS, were used to gain the purposes of the research. The results show that the low status of nutrient availability, root condition and nutrient retention are the main factors of riceland degradation. Besides, this study found that climate change, lack of organic fertilizer implementation, water scarcity and excessive chemical fertilization implementation were significant factors of land degradation based on farmers perception. In addition, some of the strategic actions were frequently implemented to minimize the degradation rate are implementing the minimum tillage, using certified seed, giving a fallow season for riceland and recycling plant residue as organic fertilizer. The study suggests implementing the proper cultivation management practices like Integrated Crop Management (ICM) and Climate Smart Agriculture (CSA) to achieve the sustainability of rice production.
