Special Issue Information

Dear Colleagues,

Throughout history, water networks have been used to develop and support human activity. As a result of our industrial activities, the water resources system has been degraded and altered. Understanding and conceptualizing water systems in modern and developed metropolitan regions will shed light on the future direction of our water–human interactions. Before we can manage and maintain water systems such as pluvial and coastal viewpoints, we must first identify human behavior and the significance of human spatial occupancy. Furthermore, now is the time to think rationally about people's values in regard to water management. As a result, numerous researchers have been invited to explore and address the following issues in this Special Issue: sustainable water resources planning, river restoration, socio-hydrology, flood mitigation, tourism in water resources management, water governance, virtual water dynamics, and island studies and humanities.

I look forward to receiving your contributions.

Calabar is a city in which 65 per cent of people live in poverty in informal settlements that have low and decreasing access to improved water. In the low-income informal areas of the city, residents are being made responsible for securing their own water supply through the use of several coping strategies. This paper explores the decreasing access to water and coping strategies for shortage in Calabar, Nigeria. It analyses two complementary pieces of data: (i) the households’ coping strategies and (ii) satisfaction with improved water services. A mixed method was introduced, and data were collected via fieldwork at three settlements in Calabar. A household survey of 360 respondents and 27 in-depth interviews were undertaken, and focus groups were conducted. The findings show that households engaged in different coping strategies with which to access water, including conservation (changing routine/reusing), purchasing (spending a significant proportion of their income on buying water) and pumping. The household’s tenure, socioeconomic status and water accessibility determine their decision to move if services are not provided. A crucial differentiation exists between a larger population being granted less access to water versus certain individuals receiving access to a greater quantity of water. The study suggests that improved access to water be secured by mainstreaming approaches and policy interventions that align with the needs of marginalized informal residents and by concerted efforts to effectively manage the water supply for sustainable development.

Wastewaters from household appliances, such as dishwashers and washing machines, are an untapped resource of recoverable water and/or nutrients. The Zero Mile system has been developed to reuse/upcycle dishwasher wastewaters through bioremediation activity carried out by an ad hoc engineered phototrophic/heterotrophic microbial consortium. The choice of both suitable microorganisms for engineering consortia and detailed knowledge on their structure, behaviour and interaction are essential to optimising consortium culture conditions and drive the biofilter container design (structure and topology). To these aims, the effect of abiotic conditions (i.e., irradiance, pH and organic load) on the microbial consortium growth and its capability to survive and thrive in different dishwasher wastewater dilutions have been evaluated. At the same time, the crucial interplay between biological and design research has allowed us to define the characteristics of the biofilter container and plan its development for the industrial application of the Zero Mile system, bringing sustainability benefits as it moves household wastewater from a traditional linear model to a more sustainable, circular approach.

Most industrialized nations have attempted to control floods through civil engineering technologies. However, these measures have failed in the face of immense natural forces. Through allomorph analysis and expert interviews, this study examined the situation of implementing urban flood rules in major Japanese cities. The river canal in the Tokyo region is mostly maintained through infrastructure, and Tokyo has a diverse network of systems linked by rivers, canals, and drainage channels, which demonstrates its dominance in structural and civil engineering flood management. In Osaka Prefecture, flood risk management is an ongoing process built on a structural engineering foundation, and local governments continue to examine and update new policies to handle the risks and difficulties produced by ever-changing flood catastrophes. To enhance public education and awareness, local administrations in the Toyama and Chiba Prefectures are implementing programs to educate locals about flood hazards and preparation. To summarize, public engagement is an important component of flood risk mitigation and management in Japanese communities. Governments may help communities become more resilient and prepared in the face of floods by involving local residents, institutionalizing public education and awareness, and building volunteer networks. This is the conclusion reached as a result of socio-hydrological intervention. Full article
