This study presents how a cluster of tributary watersheds was evaluated for geomorphology and ecosystem service economic value baselines. Tributary watersheds, although small, were focused herein as they are practical for community-based conservation. Based on the Market-Price Method, the watersheds were estimated to be worth USD49.59 ha⁻¹ year⁻¹ at the time of this study and USD58.13 ha⁻¹ year⁻¹ in 2026. The watersheds were able to meet water demand of 20.94 megalitre day⁻¹ required by the 93,084 local populations during the worst-case scenario induced by a peak El Niño and Southern Oscillation event in 2016. Collectively, the watersheds were contributing 703.87 megalitre day⁻¹; thus, water shortages are not expected in near future, unless if they are compromised. The data acquired are also compared with studies elsewhere, and some insights on other baseline metrics, risk factors and humanizing watershed conservation are discussed.

这项研究介绍了如何评估支流集水区的地貌和生态系统服务经济价值基准。支流流域虽然很小，但由于在以社区为基础的保护中很实用，因此这里重点介绍。根据市场价格法，在本研究进行时，这些分水岭的价值估计为USD49.59 ha ^-1  year ^-1，到2026 年，价值为58.13 ha ^-1 year ^-1。在2016年厄尔尼诺现象高峰和南部涛动事件引发的最坏情况下，93,084名当地居民需要20.94兆升^-1天。这些流域合计贡献了703.87兆升^-1天; 因此，除非受到影响，否则在不久的将来不会出现水短缺。还将获得的数据与其他地方的研究进行比较，并讨论了对其他基准指标，风险因素和人性化流域保护的一些见解。
