“…Based on the assessment of E.coli, pathogen reduction was considerable (Mohr et al, 2020). The project results on this technical innovation and its impacts on society and nature have been published elsewhere (Zimmermann and Neu, 2022) and did not form part of the present analysis. However, they underline the potential of developing capacity in water reuse at municipal levels for sustainable water governance.…”

In central northern Namibia, challenges in water governance related to scarcity meet needs in capacity development on municipal levels. Reuse of treated water in agriculture forms a technical innovation in urbanizing arid regions, because it potentially contributes to both improving water availability and reducing pollution from waste water in arid regions. Governing this transformative approach entails a complexity of processes and actors at different levels and in a range of sectors. The aim of this research is to assess the potential of an informal municipal partnership to (a) support capacity development in implementation of innovation in urban water systems (here: water reuse), and (b) compensate for lack of coordination in governance. Establishing a municipal partnership for wastewater treatment was part of a living lab approach analyzing the potential for water reuse, in collaboration of an interdisciplinary team of researchers, municipal decision-makers, engineers and farmers. Findings show the potential and limitations in capacity development in municipal water governance by means of an informal partnership. The lessons learnt on establishing an informal municipal partnership for learning and capacity development in water governance provide valuable insights for water governance in both research and practice, in particular but not limited to the field of water reuse as means of transforming socio-hydrological relations toward sustainability. The research thus contributes to research on water reuse governance, and to transformative research on water in social-ecological systems.

“…Water that has been recycled still needs to be widely accepted. Studies on the acceptability of treated wastewater have been carried out several times, including research conducted by Faria et al [4,[16][17][18][19]. Nonetheless, these studies only discussed the acceptance aspect of the treated wastewater but have yet to examine the quality of the treated wastewater.…”

The increased demand for water stimulates the use of treated wastewater as an alternative resource. However, there has been a constant concern from communities regarding the quality of the treated water. Thus, we present an investigation of community perception on reusing treated wastewater from ablution wastewater. This study aims to treat the ablution wastewater using the continuous electrocoagulation method and to investigate community perception of the treated wastewater. A laboratory experiment was conducted to observe the physical, chemical, and biological properties of the treated wastewater, while focus group discussions (FGD) with 10 respondents from two different mosques in Solo were carried out to understand the community perception if the treated wastewater to be reused for ablution water. The laboratory results showed that the electrocoagulation coupled with the chlorination process successfully diminished the wastewater's physical and chemical properties. the results meet the standards set by the Ministry of Health of the Republic of Indonesia through Regulation No. 32/2017 on Water Quality Standard for Sanitary Hygiene Purposes. On the other hand, the FGD results revealed two different perspectives regarding the application of treated wastewater. Over half of the respondents agreed to reuse the ablution wastewater, while the remaining declined. The decisions of those who agreed are highly affected by the Indonesian Ulema Council Fatwa regarding the status of the treated wastewater. Meanwhile, those who refused argued that currently, there is no urgency to use the treated wastewater since they are not aware of the seriousness of the issue. Furthermore, the respondents are also concerned about the possibility of virus contamination on the treated wastewater, making the water unsafe to be used.

“…Water resources are very vital for the local people in Sub-Saharan Africa (SSA) because these water body areas have wetlands that provide materials for handcrafts (Gopal et al, 2022), fishing (Onyena & Sam, 2020), and mulching (Milder et al, 2011;Yahaya et al, 2022). Freshwater resources are vulnerable to climate change and have the potential to be significantly altered, as evidenced by poor drinking and irrigation water quality, with significant implications for human societies and ecosystems (Abbasnia et al, 2019;Solangi et al, 2019;Zimmermann & Neu, 2022).…”

Variations in precipitation that affect water resources have drawn a lot of attention to climate change-related water quality issues in recent years. Point and non-point source contaminants have an impact on water quality due to seasonal rainfall variability, and rainfall events are crucial in spreading these pollutants. Sub-Saharan Africa has the least stable access to freshwater supplies. Numerous academics have undertaken extensive research on the connection between climate change and water resources, yielding significant research findings. However, there is a dearth of quantitative analysis and thorough evaluation of research accomplishments. The purpose of the study was to undertake an organized literature review on the topic of examining the relationship between Sub-Saharan Africa's water resources and climate change. In the first segment, Vos-Viewer was used to map, study the literature, and identify any gaps in order to evaluate the impact of rainfall variability on water quality. The adaptation and mitigation strategies for water availability were described in the second section. This report utilizes the VOS-Viewer bibliometric software to create a combative network and keyword co-occurrence map based on the pertinent literature on the topics of climate change and water resources in the core collection of the Web of Science database and dimension. According to the study's findings, cooperation networks are not as prominent as research networks between developed and developing nations. It was also shown that irregular rainfall affects water quality by giving the water a muddy, acidic, and turbid appearance. According to the assessment, the study's conclusions suggest that involving all significant parties and adopting strong rules can facilitate prudent water usage and management. This is crucial for the 884 million people whose survival depends on surface water resources.
