作为全球城市供水一部分的地下水系统的迅速发展,引发了有关这一基本资源的可持续管理的关键问题。然而,在许多大城市,缺乏有效的政策制度意味着开采地下水的做法是由国内家庭和钻探承包商的行动推动的。了解是什么影响了这些行为者的决定和做法、他们对地下水资源的理解以及科学知识在多大程度上影响了这种理解,这是一个目前研究不足的至关重要的领域。本文采用混合方法,探讨了尼日利亚拉各斯地区地下水抽取的国内实践。它发现,正在积极影响日常开采地下水资源的家庭与科学和国家行为者之间存在脱节。这种脱节导致家庭决策受到普遍持有的、但可能过时的地下水资源看法的影响,而不是科学证据或政策工具。地下水资源的不可见性质实际上使家庭和国家看不到改变地下水条件的规模,增加了影响实践的挑战。解决这一脱节不仅需要更多的科学知识,而且还需要与非国家行为者以及非国家行为者之间积极建立接口,通过这些接口可以对峙、讨论和分享知识。
The rapid development of groundwater systems as part of urban water supplies around the globe is raising critical questions regarding the sustainable management of this essential resource. Yet, in many major cities, the absence of an effective policy regime means that the practice of groundwater exploitation is driven by the actions of domestic households and drilling contractors. Understanding what shapes the decisions and practices of these actors, their understandings of the groundwater resource and the extent to which scientific knowledge shapes this understanding, is an area of critical importance that is currently under-researched. Using a mixed-methods methodology, the paper explores domestic practices of groundwater abstraction in Lagos, Nigeria. It finds that there is a disjuncture between the households who are actively shaping exploitation of the groundwater resource on a day-to-day basis and science and state actors. This disjuncture results in household decisions that are influenced by commonly held, but potentially outdated, perceptions of the groundwater resource rather than scientific evidence or policy instruments. The unseen nature of groundwater resources effectively renders the scale of changing groundwater conditions invisible to households and the state, adding to the challenge of influencing practice. Addressing this disjuncture requires not just more scientific knowledge, but also the active construction of interfaces with, and between, non-state actors through which knowledge can be confronted, discussed and shared.
