Urban Water Security and Resilience in Lagos, Nigeria

Le résumé fourni par la source

This dataset was produced as part of a broader academic research project examining household responses to precarious water in selected cities across Sub-Saharan Africa. The study provides insights into how inhabitants of water-stressed cities secure their water supplies and build resilience to shocks and stresses.This record includes data for the city of Lagos, Nigeria. Datasets provide the results of quantitative and qualitative research exploring the prevailing conditions for public water supplies in Lagos, experience of groundwater conditions in Lagos State, understandings of domestic boreholes for household water supplies, perceptions of water supply conditions and water use practices. The work complements a characterisation of the hydrogeology of Lagos State (published as: Holliday, L et al. (2025) Hydrogeological typologies of the aquifer systems underlying Lagos State, Nigeria. Nottingham, UK, British Geological Survey, 84pp. (OR/25/039) available at https://nora.nerc.ac.uk/id/eprint/539996).Three datasets are included. A description of each follows.1. A quantitative dataset of household perspectives was produced through a survey carried out via Computer-Assisted Telephonic Interviews (CATI). The survey was administered by IPSOS, an international survey company. The survey was administered in English. The target sample was 500 interviews, with 519 achieved. Seven respondents chose to withdraw their consent for the use of their data at the end of the survey, leaving a sample size of 512. Quota sampling was adopted to ensure a wide representation of the target population. This included a mix of gender, age, and socio-economic segments. All data was anonymised at source. All interviews were undertaken in January 2024.2. A short non-representative survey was carried out utilising googleforms and WhatsApp. The approach was not designed to gather a profile of borehole ownership, rather to get a snapshot of ownership perspectives and practices. Participants were self-selecting and informed of the survey via snowballing techniques. Participants were asked to pass the link to the survey on to others they knew who had a domestic borehole. Participants were provided with information regarding the purpose of the survey, how their data would be used and how the data would be stored. The survey was undertaken in November 2023. A total of 32 responses were received. The sample was random, owing to the snowball technique used, but likely to be skewed to those more literate and with knowledge of groundwater. All results were fully anonymised at source and no personal data was collected. The survey was undertaken in English. Respondents were asked to rank their perceived socio-economic status on a scale of 1 to 10, where 1 = lowest and 10 = highest.3. A small number of interviews were undertaken with six households who were known to have boreholes and lived in different parts of Lagos State. These households formed part of the initial survey on googleforms. Responses are intended to provide further insight into perceptions and values relating to groundwater use in Lagos State. The qualitative material is indicative only.Ethical approval for the research was provided by the Research Ethics Committee of Cardiff University’s School of Geography and Planning. All interviews have been anonymised. Participants were informed of the purpose of the research, how their data would be stored and how it would be used. Participation was voluntary and involved literate and healthy adults. All participants provided consent for their data to be used.
