Climate shock-related water insecurity has a significant impact on poverty, and vice versa, with poor people adversely impacted by different hazards. Many studies have focused on rural communities resulting in a lack of evidence on the vulnerability of urban dwellers. In this review, we explore the literature on the vulnerability of the urban poor to floods, droughts, and cholera in Sub-Saharan Africa. We particularly highlight the structural challenges and systemic inequalities that are increasing the vulnerability of the urban poor including the differential experiences of women and children. We conclude that poor people have: unequal opportunities to cope with shocks, being deprived from access to water services that wealthier households have; their needs are inequitably ignored; and cumulative vulnerability that reverberates climate shocks into smaller consequences that can have dramatic effects. Therefore, the pathways out of poverty are limited for the urban poor. This is not only due to factors of political economy such as the location and construction materials of houses, but also legacies of discrimination and their reproduction. Individual vulnerabilities are frequently increased due to the roles and responsibilities assigned to people of particular genders and/or ages. We find that these differential vulnerabilities are crucial yet poorly researched. There is also a lack of evidence for the manifold effects of drought on the urban poor. Building on the urban climate resilience literature we argue that policy makers and practitioners must consider who water security is for.

Access to water and sanitation as a basic human right is still limited within resource-poor rural settings of Africa, including Kitui, Kenya. This is exacerbated by prevailing gender inequalities which can be mediated when communities leverage on social capital. Qualitative methods were used to examine how values embedded in social capital enable women and vulnerable groups to cope with household water insecurity. How communities exploit the bonding and bridging dimensions of social capital to cope with water insecurities has gendered implications. Understanding the role of social capital is important in advancing public policy to reduce gender inequalities in water access.

Despite worldwide advances in urban water security, equitable access to safely managed drinking water remains a challenge in low- and middle-income countries (LMICs). Piped water on premises is widely considered the gold standard for drinking water provision and is expanding rapidly in small and medium urban centres in LMICs. However, intermittency in urban water supply can lead to unreliability and water quality issues, posing a key barrier to equitable water security. Leveraging mixed methods and multiple data sets, this study investigates to what extent urban water security is equitable in a small town in Northern Ethiopia with almost uniform access to piped water services. We demonstrate that, despite widespread access to piped water on premises, there is considerable heterogeneity in household water insecurity. Development of a household water insecurity index considering issues of quality, quantity, and reliability, demonstrated high spatial variability in water security between households connected to the piped water system. Reliability of piped water supply did not equate to high water security in every case, as accessibility of appropriate alternative supplies and storage mediated water security. Urban water planning in LMICs must go beyond the physical expansion of household water connections to consider the implications of spatiality, intermittency of supply, and gendered socio-economic vulnerability to deliver equitable urban water security.
