“…Households account for some 70% of the demand for water supplies in Lagos (Balogun et al 2017). At present there is an acknowledged gap between the public demand for water and the amount the State is able to supply (Lagos Water Corporation 2017; Punch Nigeria 2017), with estimates of the proportion of the population served by piped municipal water supplies ranging from around 10% to around 30% (Aina and Oshunrinade 2016, Omole et al 2016, Healy et al 2018.…”

In the absence of reliable public water supplies, many households and businesses have turned to commissioning their own boreholes, via private contractors, in order to secure personal water supplies.…”

“…The Coastal Plains Sands Aquifer is the most significant in terms of water supply and is easily exploited by shallow hand dug wells or deeper manually drilled boreholes. Balogun et al (2017) note that public water supplies are usually obtained from aquifer depths of 40-200 m (see also Longe and Malomo 1987). A deeper aquifer, at around 450 m depth, is not widely exploited for water supply (Yusuf et al 2018).…”

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 This disjuncture results in household decisions that are influenced by commonly held, but potentially outdated, perceptions of the groundwater resource rather than scientific evidence or policy instruments.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.

“…With the projected increases, it is almost certain that public sector provisions will fail to meet future demands. General shortages of water are being met by private companies operating with tankers, wells, and boreholes [19,35]. A few recent studies that have investigated land cover changes in Lagos revealed a rapid a rapid increase in built-up area between 1965 and 2005, with dramatic hydrologic consequences for the city [36].…”

Integrating System Dynamics and Remote Sensing to Estimate Future Water Usage and Average Surface Runoff in Lagos, Nigeria

The goal of this study was twofold; first analyze the patterns of water consumption in Lagos, Nigeria and use them in a System Dynamics (SD) model to make projections about future demand. The second part used remote sensing to quantify the contribution of extensive land use/cover change to urban flooding. Land use/cover dynamics over the past decade was analyzed using satellite imagery provided by Landsat Thematic Mapping (TM). Unsupervised classification was performed with false color composite using the Iterative Self-Organizing Data Analysis (ISODATA) technique in a Geographic Information Systems (GIS). The study area was divided into four different land use types during image classification: bare land, built-up area, water bodies, and vegetation. For water demand, two different scenarios of population growth including 5.5% and 2.75 % annual increase were considered. The results showed that water demand dropped by 67% of its current value when losses in distribution were reduced by 20% and population annual growth rate kept at 2.75% over the study period. Bare land and water bodies lost 1.31% and 1.61% of their current area respectively while built-up area grew by 1.11%. These changes in land use/cover changes led to a 64% increase in average surface runoff, mostly attributable to increasing surface imperviousness and the absence of an adequate urban drainage system.

Water scarcity in the fast‐growing megacity of Lagos, Nigeria and opportunities for managed aquifer recharge

In the last three decades, the world has experienced a rapid emergence of megacities. The increasing demographics, urbanization, and water demand brought severe and undesired effects on the quantity and quality of their water resources. A prime example is Lagos (Nigeria, West Africa), which is projected to become the world's largest city by 2100, and faces water scarcity challenges common to other megacities of developing countries. A literature review reveals the vast gap between water demand and regulated supply, inadequate knowledge and information on the current state of water (re)sources, and major, yet unregulated, use of groundwater. It further highlights the impacts of uncontrolled wastewater discharge into surface waters and aquifers, the role of increasing paved surfaces and blocked drainages on flooding, the inadequate supply of potable water, and the unsustainable abstraction of groundwater. Here, we examine the potential of managed aquifer recharge (MAR) to address these recurrent challenges across the megacity. The analysis reveals the opportunities and potential risks associated with the capture of wastewater, storm water, and brackish surface water for MAR. These waters, after appropriate treatment and subsurface storage may bridge the growing water supply–demand gap and mitigate the effects of groundwater (over)exploitation, including aquifer depletion, saltwater intrusion and land subsidence. Immediate efforts should focus on improving the conceptual and quantitative knowledge of Lagos' hydrogeology and groundwater resources through comprehensive spatial–temporal groundwater monitoring and socio‐economic studies of groundwater access and use. The insights provided may inform other fast‐growing coastal megacities in Africa and the wider developing world.This article is categorized under: Science of Water > Water and Environmental Change Engineering Water > Water, Health, and Sanitation Human Water > Value of Water Science of Water > Hydrological Processes
