Navigating the path: regulatory readiness and stakeholder insights in Indonesia's citywide inclusive sanitation landscape

Inadequate sanitation has catastrophic consequences for public health, standard of living, and productivity, as well as gender equality and social inclusion. Urban sanitation programmes yield suboptimal outcomes regarding long-term impact, effectiveness, sustainability, and fairness. To ensure that all urban dwellers in Low- to Middle-Income Countries (LMICs) have access to sanitation facilities that are properly maintained and safe, it is crucial to bring about a fundamental change in the urban sanitation sector through the implementation of Citywide Inclusive Sanitation (CWIS). This research analyses the sanitation regulatory framework and stakeholders' perspectives in Bandung City, Indonesia. The goal is to determine the possible obstacles and advantages of implementing a comprehensive CWIS (Citywide Inclusive Sanitation) system in Indonesia. The CWIS idea has been recognised at the national level in Indonesia. While existing legislation and policies partially govern and deal with CWIS components, there is no official programme establishment yet and limited implementation at the local level. Some challenges that have been identified include conflicting priorities in serving marginalised populations, a lack of political commitment and capacity to provide comprehensive services for all types of domestic wastewater (including grey water) and throughout the entire sanitation service chain (from containment to treatment and/or reuse and recovery), inadequate knowledge management and data transparency, a lack of incentives and penalties for local governments to meet sanitation standards, and limited motivation for meaningful and institutionalised private sector involvement. This study also delineates four crucial domains for efficiently fostering the deployment of CWIS in Indonesia.

Does the Special Allocation Fund Reduce Rural Poverty?

This study aims to analyze the effect of special allocation funds for thematic poverty reduction assignments in the fields of water, sanitation, and the field of settlement and housing on poverty in rural areas. The data collected by secondary data is number of poor people in rural areas is accessed through the BPS website, and special allocation funds for thematic poverty reduction assignments in the fields of water, sanitation, and settlement and housing are collected by accessing the Simtrada website (Information System Transfer to Regions and Village Funds) https://djpk.kemenkeu.go.id//simtrada/. The population of 34 provinces and the sample of 25 provinces in Indonesia that experienced a decrease in rural poverty were analyzed in this research. The data were analyzed by multiple regression analysis techniques. The results showed that special allocation funds for thematic poverty reduction assignments in the water sectors, and in the field of sanitation sector, did not significantly affect poverty reduction, (sig p-value 0.461>0.05 and sig p-value 0.751 > 0.05 respectively). The value of special allocation funds for thematic poverty reduction assignments in the field of the housing sector had a significant effect on reducing rural poverty (sig p-value (0.007< 0.05). This study recommends that poverty reduction funds in rural areas, especially in the field of housing, continue to be distributed and managed appropriately, so that poverty in rural areas is alleviated.

Surface engineered novel cationic surfactants with enhanced surface adsorption for environmental applications

Gemini Cationic Surfactants (GCS) have garnered significant attention due to their distinctive molecular structure, featuring two hydrophilic head groups associated with a hydrophobic spacer. This distinctive configuration enables diverse applications across various fields. Hence, the current study introduces a novel series of GCSs, ethanediyl-1,2-bis[di(2-hydroxypropyl) alkylammonium] dibromide (Cn-C2-Cn[IsoPr(OH)2; n = 9, 12 and 14) and comprehensively explore their properties, highlighting their promising antimicrobial activity. The synthesis of GCSs was validated using 1H NMR and IR spectroscopy. Dynamic Light Scattering was employed to determine the dimensions of Gemini surfactant aggregates in aqueous solutions. Surface tension analysis determined critical concentrations of micelle (CMC), minimum surface area (Amin) and concentration of surface excess (Γmax). Physicochemical properties were assessed through conductivity and surface tension analyses in aqueous solutions. The CMC, Amin and Γmax values decrease as alkyl chain length extends. Surface tension data revealed strong adsorption of GCSs at interfaces. π values (mN/m) ranged from 36.7 (C14C2C14[Iso-Pr(OH)]2) to 45.3 (C9C2C9[Iso-Pr(OH)]2). Conductivity and surface tension measurements further characterized Gemini surfactants in aqueous environments at 298 K. The size of the micelle aggregates varied between C9C2C9[Iso-Pr(OH)]2 (1.2885 nm) and C14C2C14[Iso-Pr(OH)]2 (1.9210 nm), highlighting the impact of chain length on micelle size. Hence, the study highlights significant effect of the chain lengths on Gemini cationic surfactants’ self-assembly in dilute aqueous environments. Antimicrobial tests demonstrated significant activity of Cn-C2-Cn[IsoPr(OH)]2 GCSs at varying concentrations. Antimicrobial tests showed the significant antimicrobial potential of these GCS compounds, suggesting their potential and promising applications in medical, hygiene, environmental sanitation and advanced materials sectors.

Assessment of the Status and Characteristics of Faecal Sludge Management in populated unplanned settlements of Dar es Salaam, Tanzania

This study evaluates faecal sludge management in densely populated informal settlements of Dar es Salaam, Tanzania, using suitable standardized methods. The data indicates that latrines are built with less emphasis on quality compared to the construction of houses, resulting in the use of inferior materials and technology. Various techniques are employed for emptying pits, with vacuum trucks and manual pit emptying being the predominant methods. However, lack of access to households poses a significant obstacle to vacuum truck emptying, as 39.67% cannot be reached by transportation means. The pit emptying industry faces high costs and restricted technological accessibility. Semi-manual and semi-mechanized technology innovations for hygiene emptying in less accessible dwellings have not gained sufficient appeal among inhabitants in densely crowded unplanned settlements. DAWASA owns treatment plants for faecal sludge treatment, but these are located far away, increasing transportation expenses. Implementing decentralized faecal sludge treatment plants appears to be a more effective approach. The collection and handling of faecal sludge now overlook the potential for resource recovery and re-use, which might greatly enhance the sustainability of faecal sludge management. Two government ministries have partially incorporated the faecal sludge management or sanitation sector into their health and water policies and programs, but the separation of responsibility has hindered its growth and lack of emphasis on information diffusion in urban areas.

STRATEGI KOMUNIKASI KONTROL JEJARING KEBIJAKAN DALAM GERAKAN BERSAMA RAKYAT ATASI KAWASAN PADAT KUMUH DAN MISKIN (GEBRAK PAKUMIS) DI KABUPATEN TANGERANG

Housing and settlements have a very fundamental role in the life of the Indonesian people considering the problem that often occurs is the level of housing needs that is not balanced with the level of regional capacity in providing habitable housing. As a result, a residential area will receive a load that exceeds the carrying capacity of its environment and tends to become slum. The problem of settlements is a serious problem because it is feared that it will cause fatal pockets of poverty and then cause various social problems beyond the government's ability to handle and monitor them. The Tangerang Regency government tries to clean up uninhabitable houses through the GEBRAK PAKUMIS Program. The main focus of this program is to improve the water and sanitation sector with a focal point on improving the quality of houses because a poor sanitation system is a major factor in the formation of slum areas. This study aims to analyze and find theoretical answers to the principles of policy networks and obtain new concepts about policy networks. This research uses descriptive qualitative methods, data collection techniques by means of interviews, observation, and documentation. One of the problems that is the basis for the failure of this program is the long procedure. This is something that is feared by residents, because it is considered difficult to be realized. Based on the problems faced by residents as recipients of house renovation assistance, environmental development and community empowerment, the correct communication strategy is a solution to communicate the benefits of the program to the beneficiary residents. Therefore, the communication strategy solution offered in this study is as a stimulant for local government to provide populist socialization to residents in order to bring citizens to ease in taking procedures in this program.

Assessing regulatory governance for the water and sanitation Agencies in Brazil

This paper focuses on evaluating and benchmarking the governance of regulatory agencies in Brazil's water and sanitation sector. Using a unique database obtained through the application of a questionnaire, we developed an index of regulatory governance and ranked all the agencies in Brazil that participated in the study. The index is an aggregate number of the evaluation of four key governance characteristics: Autonomy, Transparency, Accountability, and Tools & Capacity, including not only formal aspects of regulation but also indicators related to actual implementation. Based on 18 different indices, we analyze the positions of agencies with regard to different aspects of their regulatory governance, considering not only performance in each variable but also scores in the different components of each category. This evaluation identifies particular agency shortcomings regarding governance and indicates needed improvements. Although Brazil has strived to consolidate the governance design of its regulatory agencies, implementing the independent regulator model still faces several challenges. Various aspects of governance can be improved to pursue greater efficiency and quality in providing services, particularly in Accountability and Political Autonomy, where the country shows the largest number of regulatory agencies with the lowest scores. Conversely, almost half of the participating agencies show optimal scores in the Regulatory Autonomy aspect of governance. The results, for the most part, corroborate the institutional theory, in which the role of institutions is paramount for greater efficiency in providing public services, as it reduces information asymmetries and transaction costs and maximizes economic incentives.

Expanding access to water quality monitoring with the open-source WaterScope testing platform

Increasing access to water quality tests in low-income communities is a crucial strategy toward achieving global water equality. Recent studies in the Water Sanitation and Hygiene (WASH) sector underscore the importance of addressing practical concerns in water testing, such as robustness and results communication. In response, we present the WaterScope testing kit; an open-source, validated platform for drinking water quality assessment. It modernises the testing process with the inclusion of a unique cartridge/slider mechanism, machine-learning-enhanced classification and full digitalisation of results. WaterScope’s equivalency to conventional methods for quantifying E. coli is established through extensive validation experiments in both laboratory and field environments. This versatile platform provides potential to expand its applications to test other bacteria, perform colorimetric assays, and analyse clinical samples such as blood/urine samples. We anticipate that the system’s ease-of-use, portability, affordability, robustness, and digital nature will accelerate progress toward global water equality.

Transformations in the sanitation sector in the State of Rio de Janeiro: neoliberalism and regulatory changes

This article analyzes the reconfiguration of water supply services provided to municipalities across the State of Rio de Janeiro. It seeks to examines how advancements in the neoliberalization of Brazil's basic sanitation sector have contributed to a fragmentation in the provision of services and to the emergence of uneven geographies on a regional scale. This will be conducted through the lens of policy experimentation, particularly after the approval of Law 14.026/2020. The study is based on an approach concerning the commodification of public services within the context of neoliberalism, marked by a complex reformulation of regulatory mechanisms. The methodology combines an analysis of secondary data, documentary research, and thematic mapping. The results reveal that the management of sanitation services is increasingly guided by market logic, with the experimentation of controversial regulatory mechanisms that have exacerbated fragmentation and deepened territorial inequality.

By the numbers and in their own words: A mixed methods study of unmet needs and humanitarian inclusion of older Syrian refugees in Lebanon.

Older people constitute an overlooked vulnerable population in humanitarian crises. Lebanon is a small country that hosts the largest number of refugees per capita in the world. With exacerbating socioeconomic conditions, exclusionary policies against refugees, and a fragmented humanitarian system, the status of older Syrian refugees (OSRs) requires special attention. This study aimed to explore OSRs' unmet needs, coping strategies, available humanitarian services, and some indicators of the humanitarian inclusion standards focusing on the shelter, health, nutrition and food security, and water, sanitation and hygiene sectors. We conducted a convergent mixed-methods study between December 2021 and March 2022 in the North and Bekaa, including a cross-sectional survey with 461 participants and 14 semi-structured interviews. Results show that OSRs lived in inappropriate shelters (cold, leaking rainwater), especially in informal tented settlements. High rent prices pushed refugee households with elderly to prioritize paying rent at the expense of other needs such as food and medication, particularly when food cash transfer is the sole source of income, jeopardizing food security and intake. Access to dignifying and accessible bathing facilities was compromised in ITSs with shared facilities. Substantial medical costs hindered OSRs access to healthcare such as surgeries. Due to the crisis, chronic medications are not always available in dispensaries for subsidized cost, pushing OSRs to non-compliance and selling food assistance to buy medications. Soaring fuel prices hindered OSRs access to heating and transportation to receive healthcare. No efforts were reported in collecting data on OSRs' needs, targeting them with information on services, or soliciting feedback for programming, especially in the absence of any age-tailored interventions. Findings shed light on the precarious living conditions of OSRs in Lebanon and add to the body of evidence documenting their invisibility to the humanitarian response. An age-inclusive response is needed through holistic, tailored, and sustainable interventions.

Relationship between Access to Clean Water and Child Growth and Development in Kenya

Purpose: The aim of the study was to analyze the relationship between access to clean water and child growth and development in Kenya. Methodology: This study adopted a desk methodology. A desk study research design is commonly known as secondary data collection. This is basically collecting data from existing resources preferably because of its low cost advantage as compared to a field research. Our current study looked into already published studies and reports as the data was easily accessed through online journals and libraries. Findings: Access to clean water significantly impacts child growth and development in Kenya by reducing waterborne diseases like diarrhea, improving hygiene practices, and ensuring adequate hydration. Children with reliable access to clean water experience better nutritional outcomes and enhanced immune function, crucial for their physical growth and cognitive development. Unique Contribution to Theory, Practice and Policy: Ecological systems theory (Bronfenbrenner), health belief model (Rosenstock) & social determinants of health (SDH) theory may be used to anchor future studies on relationship between access to clean water and child growth and development in Kenya. Expand the implementation of effective water purification technologies and community water supply projects in resource-constrained environments. Advocate for integrated policies that prioritize water security alongside nutrition-sensitive interventions. Policies should support multi-sectoral collaboration between health, water, and sanitation sectors to address the complex interplay between water access and child nutrition.

The biofactories: Quantifying environmental benefits of the wastewater circular economy in Chile using life cycle assessment

The wastewater circular economy promises improved environmental impacts within the food-water-energy nexus. This requires verification as the global sanitation sectors seek to improve environmental impacts and achieve integrated water management. Life cycle assessment (LCA) has been used to compare novel technologies for wastewater treatment and recovery, but research addressing plant-wide improvements of co-product resource recovery using real data from full-scale plants is still needed, particularly in a Latin American context. In Chile, two wastewater treatment plants (WWTPs) have embraced the circular economy configuration, recovering treated effluent, biosolids, and biogas, in addition to implementing advanced nitrogen removal using different technologies. The LCA of these two WWTPs demonstrated that Plant A improved 8 out of 10 impact categories compared to the baseline conventional scenario, while Plant B improved 5 categories out of 10. The analysis of the two plants showed the influence of influent quality on environmental impacts and the trade-off that occurs between the different technologies implemented. Plant B generated larger environmental credits through increased biogas and biosolids recovery due to thermal hydrolysis pre-treatment and anaerobic digestion, combined with cogeneration of heat and power. Plant A implemented water recovery, which provided benefits on a smaller magnitude but to more impact categories. Therefore, both plants improved environmental impacts through the wastewater circular economy, but further improvements in system configurations are recommended in each.

Inaccessible and Unaffordable? The State of Water and Sanitation Services in Nairobi, Kenya

As the limited water resources become increasingly stressed by factors such as rapid urbanization, population growth, and climate change, the need for sustainable urban water management is more important than in the past decades. A large part of the world’s population still lacks access to clean water and sanitation, making achieving Sustainable Development Goals a challenge. Water is an indispensable resource and plays an important role in ensuring the achievement of Sustainable Development Goals. Therefore, there is a need to prioritize research on the availability, affordability, and access of water resources to promote sustainable water resource management. In this study, we reviewed academic articles and published reports from various institutions and organizations to assess water sources, infrastructure, coverage, accessibility, and affordability of water and sanitation services in Nairobi County. The study identified Nairobi’s main water sources as municipal water, primarily from surface water and groundwater. However, the capacities of the water sources, treatment plants, and wastewater treatment plants were found to be insufficient, resulting in water shortages in most parts of the city.Most of the infrastructures were also found to be insufficient and old, contributing to water distribution inefficiencies, frequent leakages, and pipe bursts which hampers water reliability. The study suggests prioritizing the water and sanitation sector in government budgets to increase infrastructure development investments and funding. Appropriate wastewater treatment methods should also be adopted and implemented to enable wastewater to meet water consumption standards and be potentially integrated into supply systems.

Institutional change for the development of urban sanitation in the Global South: A social science review

This paper analyses knowledge in social sciences about the conditions for and the process of institutional change in the urban sanitation sector in the Global South. We conducted a literature review of 148 papers. This review is organised around the six steps of institutional change proposed by Greenwood et al. (2002). Most studies focus on conditions and barriers to change, on the “legitimacy” of social or technological innovations, and the actors promoting change. The change process is rarely analysed from a long-term perspective, nor at the city scale, calling for further research.

Gendered Disparities in Water and Sanitation through an Intersectional Lens: Emphasising Women’s Perspectives

The relationship between gender and water, sanitation, and hygiene (WASH) has been a widely accepted concern among academicians, activists, and social workers in India, but research and policies focusing on gender and sanitation often fail to address the issue of the intersectionality of identities. Analysing the complex intersection of caste, class, age and gender with water and sanitation in rural India extends new opportunities to explore the complex power dynamics prevalent in society. A focus group study with 54 female participants of seven discussions and in-depth interviews has been conducted in the Hardoi district of Uttar Pradesh to explore the social relations and differences in the physical world within the context of accessibility, affordability, and availability in the water and sanitation sector. Given gendered and other social divisions, we elaborate on how women play an essential role in water and sanitation management in the household. This study also offers evidence of rural women’s experiences of intra-personal, household, and social harassment and violence related to poor or absence of sanitation and water infrastructure due to intersectional social dynamics. We also demonstrate how theorising about a single dimension of social difference ignores the different groups’ access to power, leading to inequality and disparity.

Migrating injustices in the small city: drought-impacted interstate migrant workers’ experiences in Tiruppur’s sanitation sector

ABSTRACT Climate stresses like droughts amplify economic precarity, pushing low-income, caste-oppressed communities across India to pursue temporary rural-urban migration as an adaptation strategy. This paper develops an intersectional framework on ‘migrating injustices’ to examine how caste and regional identity mediate interstate rural-urban migrants’ experiences of vulnerabilities and injustices, particularly as these experiences move and endure with migration, shaping migrants’ adaptive abilities. The framework is applied to trace the injustices that a group of 800-odd drought-impacted, caste-oppressed, landless persons from central India experience through their adverse economic incorporation as sanitation workers in Tiruppur’s privatized sanitation sector in southern India. Findings reveal that a history of caste oppression and uneven development in their home region produced unequal drought impacts for our informants, pushing them to migrate. However, migrants’ caste and regional identity combine with their climate and economic precarity to direct their migration into precarious, unjust working conditions and employer-provided, environmentally risky accommodations—both removed from local socio-political networks, undermining migrants’ ability to contest injustices in Tiruppur. In highlighting the translocal and trans-sectoral intersections between the migrating environmental, economic, and caste-based injustices for circular migrants, the paper argues that eliminating migrating injustices is crucial for achieving transformative adaptation and urban climate justice.

Experiences of community-based water supply organizations partnerships in rural areas of Colombia

Abstract Clean water for human consumption in rural areas of Latin America and the Caribbean is usually provided by community-based water supply organizations (CBWSOs). Collaborative partnerships with community-based water supply organizations (CBWSOPs) are established to tackle technical and institutional challenges concerning safe water supply. This article analyses some features of the CBWSOs and their partnerships, based on the experience of ACUANARIÑO and ASDAL – Tres Esquinas, two CBWSOs located in Valle del Cauca – Colombia, following their participation at the local, municipal (ASOOCSAS Tuluá), subnational (Asociación de Organizaciones Comunitarias Prestadoras de Servicios Públicos de Agua y Saneamiento de Colombia (AQUACOL)), national (COCSASCOL), and transnational levels (CLOCSAS). The main findings of this work, after using a participatory approach, are that initial partnerships between CBWSOs emerge from informal agreements built on the neighbourhood logic typical of rurality; however, as moving towards higher scales, agreements become more formal to allow for dialogue and discussion with governmental organizations in the water and sanitation sector. This is also a strategy for the recognition of community water management. Thus, CBWSOPs are construed under a collaborative and non-profit approach, in the manner of water operator partnerships.

The influence of public perception on acceptance of potable water reclamation schemes. The case of Diepsloot township, Johannesburg

ABSTRACT While a considerable amount of research in several parts of the world has already demonstrated reclaimed water safety and reliability for various uses, its acceptance and use by communities and households in South Africa remains very low. In this article, we use quantitative and qualitative data from a community-level cross-sectional perception survey that was carried out from 2018 to 2019 to assess water users' willingness to accept reclaimed water as an alternative source of water for domestic purposes in Diepsloot township as well as the main factors influencing respondents' perceptions. Results of this study show that there is high acceptance of reclaimed water for domestic uses. Respondents with higher levels of education were more likely to accept reclaimed water than those with lower levels of education. The assumption that the water they were using was already mixed with wastewater also increased water user's acceptance levels. The results of the study suggest that governments, municipalities, and other key actors in the water and sanitation sector should first work towards building community trust and confidence when establishing water reclamation projects for domestic use, particularly through strategic communication and awareness-raising initiatives before they can expect widespread community acceptance.

Typhoid Fever and Non-typhoidal Salmonella Outbreaks: A Portrait of Regional Socioeconomic Inequalities in Brazil.

Typhoid fever occurs in an endemic form in Brazil and is a serious public health problem in some regions. In this scenario, further research is urgently needed to identify the associations between socioeconomic factors and typhoid fever, contributing to guiding policy decisions in the country. We aimed to investigate the influence of socioeconomic disparities on the prevalence of typhoid fever and non-typhoidal Salmonella (NTS) in Brazil. A search for data from 2010 to 2019 was carried out with the national health and human development agencies. As milk and derivatives are the fourth food incriminated in food outbreaks in Brazil, analyses for detecting Salmonella spp. in commercial dairy products allowed us to assess whether the outbreaks associated with these foods are due to inadequacies in sanitary control in dairy establishments or whether they are mainly home-based outbreaks. Predictive models validated by the bootstrapping method demonstrate an association of NTS prevalence reduction with improvements in the Sanitation Service Index (Rv ≥ -8 0.686; p ≤ 0.01) and Municipal Human Development Index - MHDI - (Rv = -0.789; p ≤ 0.02). In the North, typhoid fever prevalence had seasonal variability with the rainfall, while sanitation services (Rv ≥-0.684; p ≤ 0.04) and MHDI (Rv ≥-0.949; p ≤ 0.003) directly influenced Northeast and South Brazil. Thus, the unequal distribution of investments in the sanitation sector contributed to disparities in typhoid fever prevalence among Brazilian regions. The absence of Salmonella spp. in commercial samples ratified the collected data that the outbreaks of Salmonella spp. in the Brazilian population occur mainly at residences. These findings show that implementing public health education and increasing investments in sanitation in regions with poor service can control outbreaks of Salmonella spp. in Brazilian endemic areas.

Water Utility Service Quality Index: A customer-centred approach for assessing the quality of service in the water sector

This work delves into the crucial role of service quality in the water supply and sanitation sector. Despite extensive research and implementation of quality management practices in this sector, a universally accepted definition of quality is still lacking, resulting in various service quality assessment procedures that are difficult to compare. To address this issue, the World Bank launched the ‘Utility of the Future’ (UoF) programme, aiming to guide water service providers in their efforts to become future-focused utilities that offer reliable, safe, inclusive, transparent, and responsive services through best-fit practices. Building upon the framework provided by the UoF programme, this study proposes the Water Utility Service Quality Index (WUSQI) - a composite indicator that reflects the quality of service provided by water supply and sanitation utilities from a customer perspective. Based on Data Envelopment Analysis, the Benefit-of-the-Doubt approach is employed to assign weights for aggregating the indicators representing the diverse performance dimensions. The study operationalises the WUSQI to assess the quality of Portuguese wholesale water and wastewater companies using data collected by the national regulator of water and waste services. A Multiple Criteria Decision Analysis technique, the Deck of Cards method, is used to specify an indicator of transparency from the information made available by the regulated utilities. The results show the effectiveness of this tool for evaluating and measuring service quality at the company level. Additionally, the findings highlight areas for improvement in the utilities’ performance. By enabling companies and regulators to identify areas for improvement, the WUSQI can support the delivery of high-quality services to customers.

Mozambique public investment in the water and sanitation sector and the targets of SDG6.

Many developing countries may not reach the targets of providing access to safe water sources and sanitation services for all by 2030. Census data from Mozambique show that the country's population is one of fastest growing in the Sub-Saharan region. Between the 2007 and 2017 censuses more than seven million people were added to the total population. By 2030 about 11 million people will be added to Mozambique's population. This will pose a huge challenge for the water and sanitation services. Access to these services is a fundamental requirement for the wellbeing of individuals and the development of nations. The last data from a Survey on Mozambique Family Budgets (IOF 2019/20), show that 55.7% of a total population has access to safe water sources. In contrast, access to sanitation services (31% of the population), has not kept pace with the progress made in water access. In this study, based on data from the General State Account of Mozambique, which includes the description of the annual investment made by the government and using the results of the Family Budget Surveys, it can be seen that if the average percentage values of public investment of 2009 to 2021 are the same in the following years as regards the water and sanitation sector, Mozambique will not reach the Sustainable Development Goals 6 targets in 2030.
