Description The Beles River Basin is branded as a potential national economic growth corridor. As a result, tremendous developments took place in the basin. However, the effects of changes in land use and land cover (LULC) on ecosystem service values (ESV) have not been properly assessed. This study aimed to assess the ESV status in the Beles River Basin to provide relevant information to stakeholders and policymakers from 1986 to 2019. Satellite imagery and participatory assessments of community perceptions were used to evaluate changes in LULC over the years. All images were classified using the maximum likelihood algorithm (MLA), a supervised classification technique. The LULC types were classified with an overall accuracy ranging from 89.3 to 92.1%, with a kappa coefficient of 0.87 to 0.90. The results indicated a reduction in forests (71.0%), woodlands (11.2%), and grazing lands (1.8%), while there was an increase in croplands (3568.0%), water bodies (178.1%), and built-up areas (9.4%) over the past 33 years. The total ESV in the basin were estimated to be US$1.1 billion in 1986, US$909.4 million in 2002, and US$836.5 million in 2019. The ESV losses accounted for 22.9% (US$249.3 million) over the past three decades. The observed changes in LULC also affected individual ecosystem services. The decline in ESV highlights the effects of environmental degradation in the basin. Thus, sustainable land management is indispensable to ensure the sustainability of ecosystem services in the basin.
