Researcher from the Doctoral Program in Environmental Science, Graduate School, Universitas Padjadjaran, Moh Dede, have collaborated with institutions in Indonesia, Germany, and the UK to assess the impact of vegetation cover changes on runoff characteristics in the Cisangkuy Watershed, West Java. Utilizing Cook’s method and satellite imagery from Google Earth Engine spanning 30 years, the study found that while vegetation density decreased from 1990 to 2010, it significantly increased in the subsequent decade. Despite these changes, the runoff coefficient remained consistently high at 60–63%, indicating limited improvement in water retention capacity. The study also noted a shift from moderate to low vegetation cover, which may exacerbate flood risks and water scarcity.

This research contributes to several Sustainable Development Goals (SDGs):

SDG 6 (Clean Water and Sanitation): By highlighting the relationship between vegetation cover and runoff, the study informs strategies to enhance water quality and availability.

SDG 11 (Sustainable Cities and Communities): The findings support urban planning efforts to mitigate flood risks and promote sustainable land use in the Cisangkuy Watershed.

SDG 15 (Life on Land): The research underscores the importance of maintaining vegetation cover to preserve ecosystem services and biodiversity.

The study emphasizes the need for integrated watershed management that considers both vegetation dynamics and hydrological responses to ensure sustainable water resources and environmental resilience.
