The semi-arid region of Brazil, marked by low human development indicators, has historically suffered from water scarcity, being the focus of public policies to reduce socioeconomic, water, and climatic vulnerabilities for more than a century. Among the recent initiatives, the Cisterns Program stands out as an attempt to guarantee water and food security for family farmers through the construction of social technologies for water storage, such as cisterns production. Thus, the research objective was to analyse the perception of farmers and institutional actors involved with the Program about the impact of the 2011-2018 drought on the functioning of cisterns and to discuss how water infrastructure programs can improve the adaptive capacity of farmers affected by climate change. Through semi-structured interviews with institutional actors at the regional/national level and with farmers in semi-arid Brazil in the years of 2017/2018, the results indicate that access to the social technology seems to strengthen the relationship between water and food security, and the specific capacity of farmers in dealing with climatic risks. We conclude with lessons and recommendations from the Brazilian experience that can be useful for actors from other semi-arid regions involved in water infrastructure programs.

We synthesize the interconnected impacts of Texas’ water and energy resources and infrastructure including the cascading effects due to Winter Storm Uri. The government’s preparedness, communication, policies, and response as well as storm impacts on vulnerable communities are evaluated using available information and data. Where knowledge gaps exist, we propose potential research to elucidate health, environmental, policy, and economic impacts of the extreme weather event. We expect that recommendations made here — while specific to the situation and outcomes of Winter Storm Uri — will increase Texas’ resilience to other extreme weather events not discussed in this paper. We found that out of 14 million residents who were on boil water notices, those who were served by very small water systems went, on average, a minimum of three days longer without potable water. Available county-level data do not indicate vulnerable communities went longer periods of time without power or water during the event. More resolved data are required to understand who was most heavily impacted at the community or neighborhood level. Gaps in government communication, response, and policy are discussed, including issues with identifying — and securing power to — critical infrastructure and the fact that the state’s Emergency Alert System was not used consistently to update Texans during the crisis. Finally, research recommendations are made to bolster weaknesses discovered during and after the storm including (1) reliable communication strategies, (2) reducing disproportionate impacts to vulnerable communities, (3) human health impacts, (4) increasing water infrastructure resilience, and (5) how climate change could impact infrastructure resilience into the future.

Abstract All water companies need to be able to provide safe, adequate and reliable water supplies to their customers and consumers. Yet some work under very daunting conditions. The civil war in Sierra Leone resulted in the destruction of much water supply infrastructure. It also had a devastating impact on the performance of water companies. Since the war ended in 2002 other changes continue, such as: population growth, unplanned urbanisation, environmental destruction and climate change, plus the Ebola outbreak. These pressures all have a massive impact on the natural environment and on demands for water. It is against this background that Guma Valley Water Company is trying to rebuild water infrastructure and strengthen utility arrangements for providing a reliable and affordable service on which people depend. This article describes ongoing efforts to improve water supply in Freetown. The case study highlights the multi-faceted nature of resilience building and the processes that must be undertaken if water companies are to become resilient. Long-term technical and financial support is required, however, programmes should be realistic in their expectations.

Substantial progress has been seen in the drinking water supply as per the Millennium Development Goals (MDG), but achieving the Sustainable Development Goals (SDG), particularly SGD 6.1 regarding safely managed drinking water with much more stringent targets, is considered as a development challenge. The problem is more acute in low-income water-scarce hard-to-reach areas such as the southwest coastal region of Bangladesh, where complex hydrogeological conditions and adverse water quality contribute to a highly vulnerable and insecure water environment. Following the background, this study investigated the challenges and potential solutions to drinking water insecurity in a water-scarce area of southwest coastal Bangladesh using a mixed-methods approach. The findings revealed that water insecurity arises from unimproved, deteriorated, unaffordable, and unreliable sources that have significant time and distance burdens. High rates of technical dysfunction of the existing water infrastructure contribute to water insecurity as well. Consequently, safely managed water services are accessible to only 12% of the population, whereas 64% of the population does not have basic water. To reach the SDG 6.1 target, this underserved community needs well-functioning readily accessible water infrastructure with formal institutional arrangement rather than self-governance, which seems unsuccessful in this low-income context. This study will help the government and its development partners in implementing SDG action plans around investments to a reliable supply of safe water to the people living in water-scarce hard-to-reach coastal areas.

AbstractThis chapter explores conflict and cooperation around water infrastructure in relation to contestations over water and land in peri-urban Khulna, Bangladesh. It analyses how these contestations, together with the effects of climate change and urbanization, contribute to water insecurity. These dynamics are explored by viewing the peri-urban space as a hydro-social system where physical infrastructure (a sluice gate), hydrological processes and various actors interact. Through participatory appraisal, stakeholder analysis and social power mapping, we analyse the emergence, manifestations and implications of conflicts, and how power relations influence the conflict dynamics. The chapter further presents the process and outcome of participatory actions for capacity-building of communities to facilitate their empowerment by elevating their knowledge level and negotiating capabilities toward securing water and resolving conflicts. We argue that conflicts and water insecurities of peri-urban communities largely emerge from the absence of their participation in the planning and management of water infrastructure, and their limited capacity to resist changes in the control of water and agricultural land. The chapter concludes that peri-urban communities lack the power and agency to mitigate the impacts of urbanization and climate change, while neither urban nor rural planning processes formally recognize the peri-urban and its specific water security problems and needs. This policy gap leads to increasingly complex conflicts and water insecurities. Success and sustainability of alternative livelihood choices and collective action by marginalized communities depend much on continued advocacy, cooperation among and between communities and government agencies, commitment of a trusted neutral actor, and mutual understanding and respect for each other’s positions.

Abstract. Drinking and wastewater infrastructure consists of both public and private usage. On each property parcel, drinking water can be privately provided by a well or publicly provided through a municipality. Wastewater can be a private septic tank or a public sewer. Property parcels can use all private, all public, or a combination of public and private solutions. It is important for planners and city officials to have knowledge of these systems, and it is also important to know the number of people using each type of infrastructure to prioritize resources and plan for future expansions. Visualizing the complexity of these data using separate univariate maps is aesthetically inferior involving back and forth comparisons. Further, the univariate maps represent land parcels only and do not capture the population that is using each type of water infrastructure. Our research develops a single bivariate map that facilitates the visualization of population using both public and private drinking and wastewater solutions simultaneously. The bivariate map is tended for use by planners, city officials, environmentalists, and others interested in the visualization of the spatial patterns of water infrastructure within one complete map.
