IMPLICATIONS OF ADOPTING WATER POLICY AND CASTE ON MULTIDIMENSIONAL POVERTY: EVIDENCE FROM HOUSEHOLD-LEVEL DATA IN INDIA

This paper attempts to unravel the influence of caste on water poverty while examining the relationship between the multidimensional poverty index (MPI) and the modified water poverty index (MWPI). Additionally, considering the inevitable role of policies in combatting water woes, this paper analyses the impact of drinking water policies. The empirical results show that MWPI significantly impacts MPI, and caste significantly determines both MWPI and MPI. This study also found that drinking water policies significantly influence MWPI and indirectly impact MPI through MWPI.

‘They adopt, I also adopt’: The neighborhood effects and irrigator farmers’ conversion to adopt water-saving irrigation technology

Promoting water-saving irrigation technology (WSIT) has long been recognized as an effective measure to reduce irrigation water use and alleviate regional water poverty. Neighbours are the groups with the most interaction, the most intensive contact and the most frequent communication in agricultural production. In this paper, based on a field survey of irrigator farmers of China, experiments were conducted to evaluate the contribution of neighbour effect to farmers’ WSIT behaviour and its moderating mechanism between neighbour effect and technology adoption. The results show 26.7 % farmers adopt water-saving technology and these farmers often have strong neighborly relationships. In particular, neighbor effect significantly promote WSIT adoption by 42.1 % and farmers with strong neighborly effects apply significant higher technology compared to farmers with weak neighbourly effects. Furthermore, mechanism results indicated that neighbour effects indirectly influence farmers' adoption of water-saving irrigation technology through three pathways: reducing information search costs, mitigating agricultural production risks and benefiting from the demonstration effect. Moreover, the heterogeneous results report that higher-income, lower digital and lower training frequency farmers will benefit more from the NE in terms of WSIT. Overall, this research provides a micro foundation and policy implications for the promotion of WSIT, and sheds light upon how the government can formulate relevant policies to promote the sustainable development of agricultural water resources.

Water tariffs and social equity: Towards water service connections and pricing instruments for the poor

AbstractAside from operational sustainability and efficiency goals, water tariffs also need to address the requirements of affordability and equity, in most instances, by providing subsidies to poor households. Yet, poor households are unable to enjoy the benefits of such cross‐subsidization and linked conveniences as they are unable to get water service connections. Even with a well‐designed water tariff, the inability of poor households to get piped connections results in the payment of premiums for water that is difficult to access and, at times, of questionable quality. In this paper, we assess the pro‐poor projects of three Philippine municipal water systems and suggest that providing water service connections to poor households allows these households to avoid paying the water poverty premium, as well as experience the related public health and quality of life benefits accruing from such connections. We argue that designing the best tariff for existing socio‐economic, political, and environmental realities must go hand in hand with programs that provide water service connections to poor households as this will ensure not only operational viability but also equitable water provision.

THE WATER CRISIS LOOMS LARGE IN PAKISTAN WHICH MAY FACE ABSOLUTE SCARCITY

Pakistan has the fourth-highest rate of water use in the world, as reported by the IMF (International Monetary Fund), and is the 3rd greatest water-stress country in the world.Water can be scarce for many reasons: water supply is very low compared to demand, infrastructure is inadequate, and institutions fail to balance every person’s daily needs. Water scarcity is a global problem, with the most badly and worse affected communities. In this thesis we can measure Pakistan’s water scarcity with the four main indicators. The four main indicators can be measured in a country’s water scarcity: The Water Poverty Index, Water Resources Vulnerability Index, the Falkenmark indicator, and Physical and Economic Water Scarcity Indicators. Currently, Pakistan is one of the countries where demand of water exceeds over available water supply with the giving of these 4 indicators. There are many reasons for Pakistan’s water scarcity, being increased populace, citified and computerization, climate change, unsatisfactory warehouse, residues in the existing tank, corrupt system efficiency, irrigational problem and traditional methods of farming, and insufficient finance. The possible alternatives to overcome these issues are the construction of small and large dams where possible, the construction proper irrigation system, improving the surface water governance with suitable pricing, controlling the increase in population, improving transportation, changing the existing harvesting patterns by accepting low delta crops and using saline groundwater, in conjunction with independently with salt accepting crops. Nevertheless, a unified approach is required to optimally use water resources.

Experiences of water poverty in the metropolitan area of Barcelona: implications for the Global North

ABSTRACT Water poverty, primarily understood as a problem of affordability, is increasingly important in developed countries. It burdens vulnerable households with mounting debts or deprives them of this fundamental resource. Faced with this threat, households may modify their habits to reduce consumption and seek also assistance to reduce the amount of the water bill. Both strategies imply stressful efforts, often exacerbated by unexpected events like the COVID-19 pandemic. Using semi-structured interviews with 35 vulnerable households in a working-class town near Barcelona, in this paper we blend a quantitative assessment of home water habits with a qualitative analysis of strategies to reduce water bill costs. Results reveal a strong commitment to water savings but clashes with essential household needs, particularly for children. Respondents lament that despite intense water saving, bills remain high, given water's perceived expense and limited subsidy access. In sum, addressing the issue of water poverty from the subjective experience of those struggling against it in their daily lives allows to identify situations where basic physical and mental comfort of the more vulnerable is under severe stress. These experiences and perceptions are linked to sociopolitical and economic processes such as accumulation by dispossession or ecological modernization, contributing to water poverty.

Potable water boiling can induce havoc in the water quality management arena due to the presence of microplastics

Around 30 % of the world’s population lacks access to safe water despite being a critical factor that modulates the complex dynamics of ecosystems and societies. Efficient technologies to purify water to potable form are either inaccessible or economically not viable for the majority. Water poverty and scarcity can be potentially exacerbated by the recent, widespread detection of plastics in drinking water sources, tap water and groundwater. This can induce various emerging bottle necks in global drinking water quality management. One of the most affordable disinfection techniques practiced across the world is to boil the water. Plastic pollutants in potable water sources can pose emerging water quality management bottlenecks, including leaching additives and chemicals due to water boiling. Exposure to plastic leachates in drinking water can lead to potential health risks, including oxidative stress, cancers, endocrine disruption, cardiovascular diseases, and developmental effects. The current global drinking water scenario and the emerging impacts of plastic pollutants specifically micro- and nano-plastics in drinking water, are also enlisted. Further, evidence-based prospects for drinking water quality management and impacts on one health initiative in the wake of the presence of plastics are discussed. Monitoring and surveillance, improved water treatment, and infrastructure incorporating technological innovations explicitly focusing on plastic pollutants in drinking water can ensure sustainable management and mitigation of the ill effects to a satisfactory extent. The need for firm policy instruments, partnerships between various private and public stakeholders, and the judicious use and management of potable water are contented in this article, which will steer humanity and the earth system toward achieving one health mandate and a sustainable future.

Socio-Spatial Analysis of Water Affordability at Small Scales: A Needs-Based Approach

Water affordability as a dimension of water poverty is becoming an increasing source of concern in cities of the Global North. Studies on water affordability are either based on water wants and not needs or tend to use spatial scales too large for effective analyses of local inequities that can truly guide policy actions. In this contribution, we calculate and map a Water Affordability Index (WAI) based on the minimum water requirement of 100 litres/person/day at the scale of the census tract for the Metropolitan Area of Barcelona. We also apply global and local spatial autocorrelation analyses to investigate spatial relationships between the WAI and poverty-related sociodemographic variables. Results show that, even though average WAI values are moderate, the distribution pattern of higher and lower values tends to be clustered in some districts and neighbourhoods of the study area. Bivariate correlations indicate that water affordability is not only related to poverty variables but also to the diversity of water prices. Findings exemplify how the constructed index can complement existing affordability indicators, revealing and mapping important risk groups struggling to meet the costs of essential water needs. Water affordability could be mitigated by supportive water pricing policies for vulnerable households in water poverty hotspots.

Assessing water poverty in Eastern Nepal: A study of selected Palikas across different districts

ABSTRACT ‘Water poverty’ is a hidden crisis in selected Palika's of Nepal, arising from factors such as population growth, climate change, land use alterations, and erratic infrastructure development, significantly impacting water resource quantity and quality. Addressing this requires location-specific indicators like the Water Poverty Index (WPI) for effective water resource planning. This study investigates water poverty causes in the area, analyzing five WPI components: Access, Resource, Usage, Capacity, and Environment. Introducing 10 WPI indicators and 13 context-specific variables tailored to Nepal, the research assesses water poverty across different spatial scales (metropolitan, sub-metropolitan, municipality, and rural municipality). The results show WPI scores ranging from 62.96 to 72.77, highlighting the need for targeted policy interventions. While no clear trend emerges across scales, higher resource and access scores prevail in all areas, with use, environment, and capacity scores higher in metropolitan and sub-metropolitan regions. These disparities underscore the need for tailored policies and management plans across scales to improve water poverty in the studied regions.

Measuring water poverty based on SDG 6

AbstractThe United Nations' Sustainable Development Goal (SDG) 6 refers to ensuring access to water and sanitation for all. This study develops alternatives for calculating a water poverty measure based on SDG 6. We use ENEMDU, which is a quarterly labor market survey that only for March 2019 incorporates a Water, Sanitation, and Hygiene (WASH) module. An innovative feature of this survey is that it includes information about water quality at the point of use as well as information about quality at the point of collection. Water poverty is assessed based on four dimensions: (i) safety, (ii) sanitation, (iii) hygiene, and (iv) quality. We use three different approaches to calculate our water poverty measures; the first is a deprivation approach, and the other two incorporate different weighting methods. The results indicate that our water poverty measures are highly correlated with each other (above 0.95); moreover, they are correlated with other poverty measures and social and health variables. People in water poverty are mostly racial minorities, have lower educational attainment, and are more likely to belong to the lower quintiles of income distribution This indicates that our water poverty measures are signs of poverty and deprivation in a broader sense.

Nonlinear impact of unconventional water use on water resource sustainability in China: A perspective on water poverty

Unconventional water serves as a bridge to water sustainability. However, many developing nations still have a long way to go in terms of unconventional water utilization. Different regional characteristics lead to different consumption capacities for unconventional water. Consequently, more unconventional water use (UWU) may not necessarily be positive for alleviating water poverty. However, there is a significant research gap in this field. This paper aims to answer three key questions: “Whether UWU consistently alleviates water poverty?” “Is this effect spatially heterogeneous?” and “What role do economic factors play in addressing water poverty?” For that, this paper focused on 30 provinces in China, with the sample period spanning from 2006 to 2021. To identify the mechanisms through which UWU alleviates water poverty, this paper employed a panel fixed-effects model using the Water Poverty Index (WPI) as the dependent variable and the square of UWU amount as an independent variable. The results indicate a non-linear impact of UWU on WPI, with the significance of impact influenced by GDP per capita (PGDP). Furthermore, threshold regressions were conducted with PGDP as the threshold variable. The results revealed a double-threshold effect of PGDP in the impact of UWU on WPI, displaying “U” or inverted “U” shape as PGDP develops: When PGDP is less than or equal to RMB 13,574, UWU demonstrates a negative effect on WPI; when PGDP ranges from RMB 13,574 to RMB 53,653, the effect turns positive; however, when PGDP exceeds RMB 53,653, the effect turns back to negative. The findings confirm that more UWU is not always better. Sustainable utilization plans of water resources must be tailored to local conditions, especially considering the unique characteristics of the regional economy.

A temporal and spatial assessment of water stress with water poverty index: A case study of Rajasthan

AbstractThis paper examines the evolution of Rajasthan's water poverty status and identifies key areas where intervention is needed to address the state's water woes. For this, a modified water poverty index (MWPI) has been constructed using data from the National Sample Survey (NSS). To understand the spatial and temporal change, MWPI has been computed for all 33 districts for 2012 and 2018. Although the state's overall water poverty status has improved over the given period, descriptive data analysis reveals a decline in the resource component of the index. A deterioration in the index value of some of the districts' access, capacity, and secondary sources is also a concern. Given the dwindling access to safe, sufficient, and reliable water sources and an increase in the burden of water‐related disease, the study recommends policy initiatives that urgently and explicitly address these issues.

The Socioeconomic Dimensions of Water Scarcity in Urban and Rural Mexico: A Comprehensive Assessment of Sustainable Development

Mexico faces severe water scarcity due to population growth, industrial activities, and climate change. The arid and semidesert conditions prevalent in northern Mexico, particularly in Nuevo Leon, significantly accentuate the challenges associated with water scarcity. This region is vulnerable to water scarcity due to minimal rainfall, recurrent droughts, and the increasing pressure of water demand from the densely populated Monterrey. We examined the disparities that contribute to water poverty by comparing water scarcity between rural and urban populations in Nuevo Leon. The results revealed significant contrasts in water scarcity between the two populations, indicating that different factors contribute to water poverty based on regional, territorial, and cultural characteristics. We selected the water poverty index (WPI) as an evaluation metric due to its inherent compatibility with available data sources, which facilitates its application to stakeholders and ensures comparability with other regions. This study contributes to studies on water scarcity assessment by addressing a critical limitation of the WPI. We compared three weighting methods—equal weight, principal component analysis (PCA), and analytic hierarchy process (AHP)—and identified that PCA and AHP demonstrated a superior performance compared to the standard methodology. These findings underscore the importance of considering region-specific conditions, as well as socioeconomic disparities between rural and urban populations and their role in vulnerability to water scarcity in calculating water poverty. These insights provide valuable information for customized solutions to regional challenges, representing leading actions toward sustainable development.

Assessing the spatial variation of water poverty determinants in Maharashtra, India

Abstract Water scarcity is an emerging multidimensional issue concerning not only the physical availability of resources but also is linked with poverty. The existing literature has established a relationship between income poverty and water poverty. In the Indian context, various studies have explored such issues using the Water Poverty Index (WPI), but only a few have analyzed downscale spatial units. This paper constructs district-level water poverty measures and maps its spatial heterogeneity for Maharashtra, India. Using an indicator-based approach, we aggregate various dimensions of water poverty into a single index. This composite index is formulated by normalizing the indicators and assigning weights using principal component analysis. After rescaling, the aggregate WPI score varies from 0 to 1, denoting lower to higher water poverty. The overall WPI estimate of Maharashtra is 0.47, implying high water stress. The study presents district-wise WPI information by combining the results with Geographic Information System (GIS). Our findings suggest that along with the physical abundance and accessibility to water, improvement in the determinants of capacity and environment is essential to tackle water poverty. Results highlight the intra-district variations among components of water poverty, indicating the importance of local-scale policy-making for better water resource management.

Diagnosis of the Water Access Situation in the Neighborhood of Canudos, Belém – PA

Purpose: This work aims to develop a water indicator, using the IPH (Water Poverty Index) method that can evaluate the situation of access and use of water by inhabitants of urban areas in the North region, especially in the city of Belém – PA. Theoretical framework: Access to safe drinking water, despite being a basic human right, has not been extended to all individuals, as regions with high water availability suffer from problems with access and quality of the resource offered. The Northern region of Brazil concentrates 81% of the country's water availability, however, this region presents divergent scenarios regarding access to water resources. Method/design/approach: For the methodology used in this study, variables were selected that cover the dimensions: Capacity, Water Resources, Use, Access and Environment; the Delphi methodology was also used to develop the quantification of the data obtained to determine the IPH. Results and conclusion: As a result of the field visits, we came across several complaints from neighborhood residents about the quality of the water supply service. It was concluded that the water situation in the neighborhood, despite the great availability of resources, is uncomfortable, requiring improvements in management. Research implications: The research follows a line of importance for the management of water and health issues in the city of Belém, being carried out later in other neighborhoods of the capital. Originality: The study contributes to the knowledge of water realities in the city of Belém, and shows the contrast between availability and access to water resources.

Cooling Methods for Standard and Floating PV Panels

Energy and water poverty are two main challenges of the modern world. Most developing and underdeveloped countries need more efficient electricity-producing sources to overcome the problem of potable water evaporation. At the same time, the traditional way to produce energy/electricity is also responsible for polluting the environment and damaging the ecosystem. Notably, many techniques have been used around the globe, such as a photovoltaic (PV) cooling (active, passive, and combined) process to reduce the working temperature of the PV panels (up to 60 °C) to improve the system efficiency. For floating photovoltaic (FPV), water cooling is mainly responsible for reducing the panel temperature to enhance the production capacity of the PV panels, while the system efficiency can increase up to around 30%. At the same time, due to the water surface covering, the water loss due to evaporation is also minimized, and the water evaporation could be minimized by up to 60% depending on the total area covered by the water surfaces. Therefore, it could be the right choice for generating clean and green energy, with dual positive effects. The first is to improve the efficiency of the PV panels to harness more energy and minimize water evaporation. This review article focuses mainly on various PV and FPV cooling methods and the use and advantages of FPV plants, particularly covering efficiency augmentation and reduction of water evaporation due to the installation of PV systems on the water bodies.

A Framework for Assessment of Water Poverty in Iran

The water shortage crisis is one of the main concerns that is threatening the biological security in Iran. According to available data and information, providing a framework for the assessment of water poverty in Iran seems crucial. The land-dividing unit in Iran is the province, and most of the governmental information is gathered based on this unit. In this sense, Isfahan province, which is one of the central provinces in Iran that is suffering from water crises, has been selected. The water poverty index (WPI), which is adopted in accordance with Iran’s situation, including five components of resources, access, capacity, use, and environment, has been used for each of Isfahan’s cities. “Capacity” and “use” has the greatest correlation, and it seems any advancement in water utilization for economic purposes might result in increased capacity, and vice versa. Also, there is a positive correlation between WPI and components of access, capacity, use, and environment. It can be interpreted that the lack of access to water services may be due to a lack of income or education. Finally, access, capacity, and use showed the strongest relationships between WPI and its subcategories. Therefore, these three elements should be the main focus of any initiative to manage the water poverty in Isfahan province.
