农村地下水供应基础设施（主要是配有手动泵的钻孔）的可持续性仍然是一个挑战。本研究评估千年发展目标 (MDG) 中规定的覆盖目标是否无意中增加了可持续管理供水基础设施的挑战。此外，分散服务的推动增加了供水资产的财务负担。从马拉维 68,984 个供水点的综合实时数据集中提取了 14,943 个 Afridev 手泵钻孔的样本，以调查重点转向 2030 年议程时的可持续性负担。结果表明，千年发展目标时代的覆盖范围的推动影响了资产的可持续性。缺乏积极主动的大修措施和不合标准的钻孔施工以及老化的基础设施导致分散供应的功能减少。此外，需要进行昂贵的修复才能使资产达到运营标准，而通常依赖外部支持。加速实现覆盖目标导致了基础设施的不可持续发展，这对未来产生了进一步的影响。这些发现支持可持续发展目标 (SDG) 投资规划需要从关注覆盖目标转向关注优质基础设施和主动监测方法，以减轻社区未来的负担。
The sustainability of rural groundwater supply infrastructure, primarily boreholes fitted with hand pumps, remains a challenge. This study evaluates whether coverage targets set out within the Millennium Development Goals (MDG) inadvertently increased the challenge to sustainably manage water supply infrastructure. Furthermore, the drive towards decentralised service delivery contributes to the financial burden of water supply assets. A sample size of 14,943 Afridev hand pump boreholes was extracted from a comprehensive live data set of 68,984 water points across Malawi to investigate the sustainability burden as emphasis shifts to the 2030 agenda. The results demonstrate that the push for coverage within the MDG era has impacted the sustainability of assets. A lack of proactive approaches towards major repairs and sub-standard borehole construction alongside aging infrastructure contributes to reduced functionality of decentralised supplies. Furthermore, costly rehabilitation is required to bring assets to operational standards, in which external support is commonly relied upon. Acceleration towards the coverage targets has contributed towards unsustainable infrastructure that has further implications moving forward. These findings support the need for Sustainable Development Goals (SDG) investment planning to move from a focus on coverage targets to a focus on quality infrastructure and proactive monitoring approaches to reduce the future burden placed on communities.
