摘要

东南亚很容易受到气候变化的影响,其一半以上的人口最近已经受到干旱、洪水和海平面上升的影响。本报告回顾了印度尼西亚目前面临的水资源挑战,这些挑战很容易受到气候变化日益加剧的影响。本文介绍了印尼与原始水源相关的水资源和饮用水资源基线评估。为回应人们对破坏全国供水的长期挑战的日益关注,本研究对饮用水安全监管进行了分析。为此,我们进行了一项文献调查(2000-2023 年间发表的 100 篇研究报告),以确定地区地下水资源的可持续性和水安全问题。本研究的主要发现包括:只有 10% 的降雨渗入地下水,而 70% 的河流受到生活垃圾的严重污染。在研究期间,2020 年的可用水量下降到每年 1200 立方米,只有 35% 的资源在经济上可以再利用。据估计,印度尼西亚的供水缺口为 5.5 立方米/年,到 2021 年将满足约 67% 的人口用水需求。虽然这一缺口可以通过私人供应商来弥补,但 2030 年的供水/需求预测表明,这一缺口无法通过增加供水来弥补。

Implications of climate change on water quality and sanitation in climate hotspot locations: a case study in Indonesia
Southeast Asia is vulnerable to climate change with over half of its population already being impacted by drought, flooding, rise in sea levels recently. This work reviews the current water resource challenges in Indonesia, prone to the rising impacts of climate change. A baseline assessment of Indonesia's water and drinking water resources related to its original sources is presented. In response to a growing concern over chronic challenges that undermine water supply nationwide, this study analyses drinking water safety supervision. To accomplish this, a literature survey (100 studies published during the 2000–2023 period) was performed to identify regional groundwater resources sustainability and water security issues. Among the main findings of this study, only 10% of rainfall infiltrates to the groundwater, while 70% of its rivers are heavily polluted by domestic waste. During the study period, water availability decreased to 1,200 m3/year in 2020, with only 35% of the resources being economically feasible for reuse. The water supply deficit in Indonesia was estimated to be 5.5 hm3/year with roughly 67% of the population's water demand satisfied in 2021. Although this deficit might be fulfilled with private vendors, water supply/demand forecasts in 2030 suggest that the gap could not be closed by increasing water supply.
