Most of the peatland degradation was caused by land fires, water mismanagement, and mining activities. Indicators of degraded peatlands based on the kind of land cover in the field are characterized by (1) shrubs, and (2) barren lands (open areas of ex-mining land). This study aims to identify, distribute, and determine the dynamics and prediction of the existence of degraded peatlands in Kepulauan Meranti Regency, Riau Province, Indonesia. The methods used were spatial analysis and CA Markov analysis. The data used: Landsat imagery 1999–2018, Regional Spatial Planning (RTRW) map, map of landform and soil, hotspot data, and peatland data. The results of this study show that the maximum land degradation area of 280.366,8 ha occurred in 2000, and the smallest of 154.365,01 ha occurred in 2010. The increase in land degradation is due to an increase in forest and land fires in the area. The factor driving the increase in forest and land fires is the practice of clearing land by burning. The prediction analysis of land degradation in 2030 shows that degraded peatland has decreased by 2.471 ha which includes degraded peatland in protected areas and cultivated areas.
