Climate resilient development has become the new paradigm for sustainable development influencing theory and practice across all sectors globally—gaining particular momentum in the water sector, since water security is intimately connected to climate change. Climate resilience is increasingly recognised as being inherently political, yet efforts often do not sufficiently engage with context-specific socio-ecological, cultural and political processes, including structural inequalities underlying historically produced vulnerabilities. Depoliticised approaches have been shown to pose barriers to concerted and meaningful change. In this article, world-leading water specialists from academic and practitioner communities reflect on, and share examples of, the importance of keeping people and politics at the centre of work on climate resilient water security. We propose a roadmap to meaningfully engage with the complex politics of climate resilient water security. It is critical to re-politicise climate resilience to enable efforts towards sustainable development goal 6—clean water and sanitation for all.

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 have developed a household water security index that considers issues of quality, quantity, and reliability. We demonstrate that there is high spatial variability in water security between households connected to the piped water system. Moreover, 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.

Urban water security is of critical global and local importance. Across many parts of low- and middle-income countries, urban water security either remains elusive or is becoming stressed. Rapid urbanisation and climate change are two key drivers of resource insecurity and at the forefront of urban water discourse. However, there are manifold and complex socio-political processes functioning alongside these megatrends that are often underemphasised. Drawing on three urban case studies in Ethiopia, we highlight these structural issues and the need for their continued consideration to fully understand and address urban water insecurity. Household water-use surveys, semi-structured interviews and participatory exercises with community residents, stakeholders and informal water vendors were used as part of a mixed-method approach in three urban areas. We found that government-managed urban water supplies were intermittent and unsafe, resulting in economic, health and time-use burdens for households, and that the socio-political dimensions reproducing urban water insecurity have historical roots. We argue that the uncertainty of climate change and unprecedented urbanisation do not offer sufficient explanation for why urban water insecurity persists. Moreover, we call for caution in only employing these narratives, to avoid obscuring deeply rooted challenges within socio-political systems. We call for socio-political processes to continue to be a central component of future interventions that seek to improve urban water insecurity.

We propose the concept of ‘agri-vector water’ (AVW) to refer to water allocated to towns to maintain urban-based agricultural services that support rainfed farming in surrounding areas. AVW captures the idea that highly scarce ‘blue water’ can be productively used in this way to support rainfed ‘green water’ rather than be applied as consumptive irrigation, especially when the latter exacerbates water shortages during drought and dry seasons in arid and semi-arid regions. To illustrate, we present two case studies from Ethiopia.

As populations grow and climate patterns change, difficult trade-offs in water security must be made. Re-allocation of water resources and re-distribution of water security outcomes will inevitably raise questions of equity. Equity is a central component of water security but often underemphasised, hence we still lack nuanced insights to how equity is understood and operationalised by water managers and users. The concept of risk is increasingly used in water security policy and practise but has been weakly integrated with equity considerations. We offer a contextual study that explicitly unpacks risk and inequity in water security across multiple scales; we have analysed lived water experiences and their hydrosocial drivers in a major river basin in Ethiopia. This is based on 61 interviews from seven rural kebeles, government organisations at woreda, zonal, regional and federal level and local and international NGOs as well as 17 industrial water user surveys. With our findings, and drawing on existing studies, we offer a theoretical framework for embedding water risk in equitable water security considerations. We find that when water risk is (re-)oriented from a biophysical framing, towards one centred on water-related values, it can be suitably embedded within hydrosocial framings of water security. This approach offers unique insights into how inequities are understood, within uneven power and political dynamics, which is critical for interventions that seek to deliver more equitable water security and meet social development targets.
