| 英文摘要 | Groundwater resilience on small islands, especially low-lying carbonate islands like Tunda, is vulnerable to an expanding population, demand exceeding supply, contamination from human and animal waste, and climate change-related impacts. This study aims to evaluate the resilience of groundwater resources on Tunda Island, Banten, Indonesia, in response to anthropogenic activities and climate change-induced consequences. The data were compiled and collected from the official Indonesian government websites and direct field observations. Typically, the aquifer system of Tunda Island's Quaternary Reef limestone is formed through fissures, fractures, and dissolution, which has low productivity, low to high transmissivity, and a discharge rate of more than 10 L per second. Analysis of climate data reveals that January has the highest average monthly precipitation, with 283 mm, while August has the lowest, with 50 mm. This is proportional to monthly potential water recharge, with amounts of 156,386 m3 in January and only 27,706 m3 in August. The groundwater levels are higher than the mean sea level, ranging from 1.07 to 8.71 m, with flow directions from the inland (recharge) to the coast (discharge). The water quality is generally good, especially on higher terrain located some distance from the coast. However, overall coliform and E. coli levels were marginally elevated. Population growth from the last decade (2012-2022) and ten drought events caused by El Nino and a positive Indian Ocean Dipole (IOD) from 1979 to 2022 have not yet had a significant impact on Tunda Island's groundwater resilience. Similarly, the increase in the number of visitors between 2019 and 2021 has had no effect on the island's water security. However, these anthropogenic and natural stresses will inevitably deplete the island's water supply in the future. Hence, water management strategies, including rainwater harvesting, enhancing water-use efficiency, conserving water through an artificial recharge system, and protecting and restoring coastal ecosystems, were required to maintain the water supply and its sustainability. |
