Abstract

Mangrove ecosystem health in the East Surabaya Coastal region continues to experience dynamics influenced by changes in land use and pond activities in the surrounding environment. This study aims to (1) analyse changes in the distribution of mangrove ecosystems using Sentinel 2A imagery in the East Surabaya Coastal Area in 2017 and 2023, (2) analyse changes in mangrove ecosystem density using Sentinel 2A imagery in the East Surabaya Coastal Area in 2017 and 2023, (3) analyse changes in the distribution of mangrove ecosystem health using Sentinel 2A imagery with Mangrove Health Index (MHI) techniques in the East Surabaya Coastal Area in 2017 and 2023. The results showed that mangrove ecosystems in the East Surabaya Coastal region experienced extensive changes between 2017 and 2023, with an increase of 115.87 ha. In detail, the dynamics of mangrove ecosystems showed that 182.33 ha decreased, and 298.20 ha increased, and 604.16 ha could maintain its area. The density of mangrove ecosystems in East Surabaya Coast in 2017 and 2023 was dominated by a density class that remained close to 674.66 ha with the largest density change occurring from the close class to the medium class of 77.32 ha. There is no significant change in the level of mangrove ecosystem health in East Surabaya Coast in 2017 and 2023. Mangrove ecosystem health remains dominated by poor health covering 782.53 ha in 2017 and 896.30 ha in 2023 with the most extensive health change occurring from moderate to poor health class covering 1.70 ha. The increase in mangrove ecosystem area is influenced by the availability of natural seedlings from existing mangroves and conservation activities from Wonorejo Mangrove Ecotourism and Surabaya Mangrove Botanical Garden, while the health of mangrove ecosystems is influenced by environmental conditions exposed to waste pollution from surrounding rivers and pollution from pond activities.
