Karst ecosystem services and land-covers dynamic: case study from Karst of Tuban and Tuban Regency, Jawa Timur, Indonesia

Abstract

Karst area provides numerous ecosystem services from the interaction among its components of water, soil, and vegetation. However, a threat from unsustainable practice and resource overuses could diminish those services. Therefore, it is critical to steadily monitor the karst dynamics, especially in high-activity karst like the Karst of Tuban. This study aims to capture the karst dynamic, particularly the land-use change and how its impact on ecosystem services (ES). To achieve the research objective, an artificial intelligence tool of ARtificial Intelligence for Ecosystem Services (ARIES) is employed. ARIES examines a dataset for 6 years intervals beginning in 2012 to 2018 consisting of land-use and ecosystem change and ES using 150 m spatial resolution data. During that period, Tuban Regency undergoes a heavy change in artificial surface and a significant decrease in the water body and cropland. From the result, ARIES as the ES estimation tool can be used for robust calculation and preliminary study due to its limitation. The results also show the urge to address the issue of carbon storage and sediment regulation in the karst area and the land-cover changes in the Tuban Regency.
