Introduction
Water scarcity is a significant global health concern, affecting over one billion people worldwide [

8]. The contributing factors to water scarcity comprise economic growth and population growth which contribute to the increasing pressure on water sources [
2]. Water shortages threaten the livelihood of many communities around the world [
2]. In developing countries, inadequate access to safe drinking water and sanitation exacerbates the risk of waterborne and neglected tropical diseases [
9,
10,
11]. The risk to waterborne diseases is raised by the use of alternative water sources which in most cases are contaminated and unsafe for human consumption [
5]. In addition to the heightened risk exposure to illnesses, socio-economic development is also constrained immensely by water scarcity [
2]. For instance, water availability plays a critical role in various industries including agriculture which is dependent on water [
12]. The United Nations recognizes access to safe water and sanitation as human rights [
13], yet many countries, including South Africa, struggle to meet this basic need [
14]. South Africa's water, sanitation and hygiene (WASH) challenges are compounded by inadequate water infrastructure [
14] despite the constitutional guarantees of access to safe water [
15].
South African rural areas are disproportionately affected by limited access to improved water and sanitation services [
14,
16,
17,
18,
19,
20]. In South Africa, water scarcity is a political invention that excluded and marginalized black people from accessing improved water sources [
21,
22]. This invented limitation to access clean water for domestic use was integral to colonial and apartheid strategies [
21,
22]. Almost 20% of the rural communities in South Africa still lack access to reliable sources of clean water, and about 25% have no access to basic sanitation facilities [
23]. Post apartheid era in South Africa, different factors including climate change, agriculture, population growth and inadequate water infrastructure worsen the challenge of water scarcity particularly in rural South Africa [
24,
25]. An understanding of water scarcity plays a critical role in the formulation of policies at global to local levels [
2]. This study investigated factors that influenced water scarcity in rural communities of uMkhanyakude district, KwaZulu-Natal province, South Africa, with a focus on community engagement and locally driven development processes.
Results
The findings indicate that the water scarcity challenges in uMkhanyakude community were attributed to a trifecta of factors: inadequate infrastructure, political inaction, climate change and population growth.
Infrastructural Challenges
Almost all the participants from both the KII and the FGDs reported lack of water infrastructure as the main contributor to water scarcity in uMkhanyakude District. Out of ten participating villages, only Ndumo and Makhana had basic water infrastructure in place. Majority of villagers from these two villages had piped water in their yards with exemption to community members who had recently relocated to these two areas. Residents from the remaining eight villages reported extreme water scarcity which forced them to access water from contaminated alternative water sources for domestic use. The alternative sources of water used included rivers and community excavated well which were often shared with animals. Some participants reported:
We fetch water from the river, which is also used by cows and goats, resulting in dirty water. We must wait for the water to clear before drawing it for human use.

During the drought, we had to dig for water by the river, but it was hard to find and dirty, leaving red marks on the bucket.
A female aged 46, KII, Madeya
In addition to infrastructural challenges, lack of efficient tools for communities to construct safe water sources by themselves was a major obstacle. This deficiency rendered the task laborious, straining, and environmentally degrading. Participants reported relying on rudimentary tools, such as picks and shovels, for digging water sources. This approach resulted in prolonged construction periods, with villagers dedicating long hours per day to this task. The environmental degradation was likely due to the destructive nature of manual digging, which led to soil erosion, habitat destruction, and water source contamination:
We dig with picks and shovels, and it takes the whole day. Sometimes we get tired and try digging at another spot if the water does not surface.
A male religious leader aged 65, KII, Madeya
We walk long distances to collect water, about 3km away. We use donkeys because it's far, and even then, we have to dig for water.
A male religious leader aged 65, KII, Madeya
We depend on rain for water supply. During dry seasons, we hire vehicles to fetch water from other villages with water.
A male aged 65, KII, Madeya
These findings highlight the significance of adequate water infrastructure in ensuring access to clean water, improved sanitation and reduced risk of waterborne diseases. The findings further highlight the urgent need for alternative, more sustainable solutions to support water source construction in villages lacking infrastructure. The physical and the environmental burdens associated with manual digging methods underscore the importance of investing in efficient tools and technologies to support the development of safe and reliable water sources.
Political Gesturing
Political gesturing emerged as a significant factor to water scarcity during the interviews. The phenomenon was also perceived as a hinderance to effective service delivery, particularly in communities plagued by inequality and poverty. Politicians leveraged the water crisis for political gain, frequently making unfulfilled promises to address the issue. This was evident in the participants' narratives:
We engage with ward councillors, who promise to provide water, but these promises remain unfulfilled due to lack of budget allocation.
A male aged 50, KII, Mgedula
In 2019, we met with the mayor, who promised to deliver water, but we are still waiting; it's a waiting game, as promises are not kept.
A female aged 41, FGD Mbandleni
We complain to councillors, who promise assistance but fail to deliver.
A male aged 38, Mixed FGD Madeya
Ihave approached the Shemula Water Scheme authorities and municipalities, and they promised to address our water issues, but no action has been taken.
A female aged 68, KII, Madeya
Inconsistent local government interventions were reported during the interviews. Participants were aware that infrastructural development solutions for safe water access would take a long time to put in place. In the interim, government authorities had promised to provide clean water through truck tankers to communities struggling with access to safe water. However, water deliveries were reported erratic and unreliable. Majority of the villages reported infrequent and long waiting periods for water deliveries:
Promises of regular water deliveries via truck tankers were made, but nothing materialized.
A female aged 51, FGD Mbandleni
Water trucks have not arrived in our village for almost 10 months.
A male aged 50, KII, Mgedula
We are still waiting for water cans to be dispatched to our tanks as promised by the mayor.
A female aged 47, FGD Mbandleni
The communities expressed a need for alternative solutions, such as boreholes, to address the inconsistencies in water supply as expressed by one of the female KII participants from Mahlabeni: “Boreholes would be useful for accessing water during periods of tap water scarcity and delayed water truck arrivals”.
These findings highlight the need for reliable and consistent local government interventions to address the water crisis in these communities. The findings also show the negative consequences of poor accountability on officials which led to poor service delivery, exacerbating the water crisis in the affected villages. The findings also highlight the need for effective governance to address this critical issue.
Climate Change Impacts
The study findings revealed that drought, exacerbated by climate change, had far-reaching and devastating effects on the district's ecosystem and water resources. Participants consistently highlighted the struggles associated with drought:
We had to dig for water by the river due to drought and lack of rainfall.
A female aged 46, KII, Madeya
Water scarcity is alleviated by rainfall, but without it, accessing water becomes a significant challenge here.
A male aged 65, KII, Madeya
Drought forces us to fetch water from distant areas like Ndumo where they have piped water in their yards.
A male aged 35, FGD Mbandleni
Recent rainfall has temporarily alleviated water scarcity because we have collected water in our tanks.
A female aged 27, Mixed FGD Madeya
In South Africa, climate change manifests in increased temperatures, leading to rainfall unpredictability and droughts. These changes have compromised the already inadequate water supply and quality in the district, exacerbating the struggles faced by communities. The study's results underscore the urgent need for climate-resilient water management strategies to mitigate the impacts of drought and ensure sustainable water access in the district.
Population Growth
The villages with basic water infrastructure, namely Ndumo and Makhana, faced an additional challenge, population growth. As the population increased, so did the demand for water and other essential services, placing a significant pressure on existing supplies. This growth led to a surge in water demand, which outpaced the capacity of the current infrastructure. Qualitative data revealed that new community members, who migrated from other villages, did not have access to piped water in their yards yet. While waiting for their own water connection, they relied on fetching water from their neighbours’ residences:
Not all houses have taps in their yards. Some people have connected their own pipes, but newcomers do not have taps yet. They usually access water to use at their homes from their enamours.
A male aged 45, KII, Ndumo
Not everyone in our area has a tap in their home. We heard that the water reservoir has limited water supply and on the other side our village keep growing because of the other people coming to stay here. That means some people will not have water until the current problem of limited supply is sorted.
A male aged 47, KII, Ndumo
This finding suggests that population growth has exacerbated the water supply challenges in these villages, highlighting the need for infrastructure expansion and upgrading to meet the increasing demand. The authorities' concerns about the limited water supply reservoir capacity further emphasize the urgency of addressing this issue.
Challenges Caused by Water Scarcity
Use of Unsafe Water Sources
As their last resort, some community members in the study areas relied on unprotected and untreated water sources, thereby exposing themselves to significant health risks. Participants revealed that they struggled to access clean water, and those who could afford resorted to pay for water transportation from elsewhere:
“Water is generally not sold here. However, if we transport it to our village from other villages with water, then we have to pay for transport. It is difficult for the poorest who cannot afford to pay for water transport. Then they usually collect water from places shared with livestock. These rivers are also used to wash laundry and swimming”
A male aged 37, FGD Mbandleni
The findings highlight the urgent need for interventions aimed at improving access to safe and clean water, as well as promoting hygienic practices and water management strategies. The findings also highlight the need for leaders to ensure access to safe and protected water sources to mitigate health risks. The reliance on unprotected and untreated water sources has significant implications for community health, particularly in the context of waterborne illnesses.
Gender Inequality
Water scarcity exacerbates gendered divisions of domestic labour, with women and children disproportionately burdened with fetching water for household consumption. Participants revealed varied perspectives on gender roles in water collection.
Women and children typically fetch water, but it's challenging for children due to the river's location in the forest.
A female aged 47 in a FGD at Mbandleni
Another female aged 52 from a mixed FGD from Madeya explained a cultural dynamic regarding fetching water: “In Zulu culture, women traditionally fetch water, but now everyone contributes”. This was supported by one of the male participants aged 38 in the same mixed FGD: “I don't fetch water; it's not my department. I might help with fetching water from the river using a car”. A minority of male participants explicitly rejected traditional gender roles, opting out of water collection duties:
Fetching water is everyone's chore; we all use water, so we should all contribute.
A male aged 33 from a FGD from Makhana
The results contribute to the existing research related to gender and water, emphasizing on the importance of considering the complex social dynamics and the evolving gender roles in the context of water scarcity. Additionally, this finding underscores the critical need to address gender disparities in house chores.
Navigating Water Scarcity
Despite facing severe water scarcity, participants demonstrated remarkable resourcefulness and resilience through various coping mechanisms. They relied on alternative water sources comprising wells and travelled to collect water for domestic use from neighbouring villages with available water. Community members used multiple containers to store water to mitigate the intermittent water supply. Furthermore, participants reused water for multiple purposes, such as washing dishes and watering gardens. Multiple service delivery protests were also organized to express dissatisfaction with water supply services, although these often did not yield expected outcomes. Repeated disappointments led some community members to become disengaged, opting not to act despite the ongoing water scarcity in the study area. Protests and alternative strategies provided only temporary relief, highlighting the need for sustainable solutions to water scarcity. This study highlights the resourcefulness of communities in navigating water scarcity. However, it also emphasizes the urgent need for effective, sustainable solutions to address this critical issue.
Discussion
This study investigated the factors contributing to water scarcity in rural KwaZulu-Natal, South Africa. The findings revealed that infrastructural challenges, political gesturing, climate change, and population growth were major contributors to water scarcity in the region. Lack of access to clean water increased the risk of waterborne illnesses, highlighting the need for improved Water, Sanitation, and Hygiene (WASH) services [
33]. The scarcity of clean water compromises individuals' ability to practice good hygiene and sanitation [
11].
The study found that rural communities relied on unprotected wells, rivers, and dams as their sources of water for domestic use. Unfortunately, these water bodies are risk factors for contaminated water [
34]. Inadequate, and lack of water infrastructure forced residents to walk long distances to fetch water, leading to structural social problems and gendered division of labour [
11,
35,
36,
37,
38]. In many rural settings confronted with water scarcity, women and children often take the responsibility to fetch water from distant alternative water sources [
11,
37,
39,
40] thereby exposing them to multiple health and social risks. The South African government should invest better in adequate water infrastructure to ensure access to clean water for domestic use in both urban and rural settings.
Political gesturing and lack of government commitment to improved public service exacerbate poor service delivery outcomes [
41]. This phenomenon is consistent with existing literature, which highlights the negative impacts of political gesturing on service delivery and development outcomes [43,44]. The study's findings underscore the importance of addressing political gesturing to ensure effective service delivery and improve the lives of marginalized communities. Protests are a means for communities to communicate dissatisfaction, but complacency can lead to inaction [
42]. Politicians and community leaders should avoid creating unrealistic expectations to gain favour with communities [
43].
Climate change contributes to water scarcity, with anticipated negative impacts on equitable access to clean water [
20,
44,
45,
46]. Erratic rainfall and frequent droughts threaten water supply, agricultural sector, and food security [
47,
48]. It is critical that countries, including South Africa put in place climate-resilient water management strategies [
49] to ensure sustainable water access even in rural areas.
Rapid population growth increases demand for water, leading to severe shortages [
2,
18,
20,
50,
51]. The affected communities are usually forced to reuse greywater and store water to maximize limited resources [
47]. This phenomenon is consistent with existing literature, which highlights the impact of population growth on water resources and infrastructure [
52,
53]. The integration of population growth projections into water resource planning and management strategies is critical to ensure sustainable and equitable access to water. Additionally, South African government should implement sustainable solutions to address water scarcity, including improved WASH services, infrastructure development, and climate change mitigation strategies to mitigate water scarcity in rural areas.
