1. Introduction
The negative impacts of poor municipal solid waste management and the need to minimise the amounts of such a waste stream are of concern for environmental management in many countries. This is especially true in developing countries, where ineffective municipal solid waste management is leading to poor sanitation, increased public health risk, and other environmental challenges regarding its collection, storage, transportation, and final disposal through landfilling [
1,
2,
3,
4]. The composition of municipal waste is heterogenous and varies amongst countries and regions. The composition of this waste stream is largely a function of differences in cultures and lifestyles, levels of industrialisation, standards of living, degrees of recycling, and other options to reduce it [
5,
6,
7]. Internationally, municipal solid waste usually arises from educational, institutional, commercial, and residential community sources as well as open spaces and streets in a given municipal area, and includes a variety of throw-away items [
3,
8,
9]. These items entail all kinds of papers, garden wastes, discarded foods, plastics, packaging wastes, discarded furniture and clothes, bottles, appliances and batteries [
2,
10,
11].
In South Africa, municipal solid waste is classified as general waste and is comprised of business waste, building and demolition waste, inert waste, and domestic waste [
12]. This waste stream is increasing in both urban and rural areas due to accelerated population growth and economic activities [
13]. Whereas the amount of municipal solid waste in 1997 was 42,230,000 m
3 by volume, in 2010 it increased to 68,626,526 m
3 [
14]. Also, 97 million tons of municipal solid waste was disposed of in landfill facilities in 2011 without any form of recycling, inevitably placing large stresses on receiving waste disposal sites, apart from the negative environmental impacts associated with their daily operations [
14]. Although this waste is regarded as useless and not needed at the point of final disposal, if recycled effectively, its quantities can be substantially decreased if its usable fraction can be recovered from the waste stream for reuse [
5,
6,
7,
15]. Hence, local governments should not only ensure that municipal solid waste is collected and disposed of in landfill sites in a cost effective and sanitary manner, but also ascertain that recoverable components are reused and recycled efficiently [
16]. Effective municipal solid waste management and its minimization has proven to be a very complex function in many countries, however, and is dependent upon adequate institutional capacity, enforcement of environmental laws and regulations, cooperation and collaboration between municipal governments, as well as heightened public awareness amongst community residents [
2,
17,
18,
19].
Even so, in South Africa there are marked degrees of unevenness in the provision of waste management services amongst communities due to their geographical location and associated socio-economic characteristics [
12,
13]. Some of these discrepancies are ascribable to the impact of previous apartheid policies which enforced separate development priorities for different population groups based on race. In most cases, low income and rural areas are receiving poor waste management services that are inferior to high income areas [
14]. The existence of these spatial inequalities necessitates recognition of the fact that South African municipalities have differentiated capabilities in the delivery of waste management services, especially if some uniformity in the scope and quality of municipal waste management services is to be achieved [
20].
The political structure associated with municipalities in South Africa is organised into five different categories: (A) metropolitan municipalities (2%); (B1) municipalities with the largest budgets (9%); (B2) municipalities with larger populations and towns (12%); (B3) municipalities with relatively small populations (47%); and (B4) municipalities which are mainly rural (30%) [
14]. Whereas (A) metropolitan municipalities dispose of large amounts of municipal solid waste (14,514,400 tons/annum), others deal with relatively lower amounts, ranging from 3,269,364 tons per annum (B1—municipalities with larger populations and towns) to 1,162,490 tons per annum (B4—municipalities which are mainly rural) [
14]. Furthermore, most metropolitan municipalities in South Africa have better resource endowments in terms of revenues and staff with appropriate qualifications and skills and have an enabling infrastructure, therefore the proportion of households that receive waste management services within their jurisdiction tends to be very high (80%) [
14]. By contrast, communities located in rural municipalities have limited access (20%) to waste management services due to institutional and capacity constraints as well as socio-economic barriers [
14]. Regardless of these discrepancies, Section 24 of the South African constitution states that all citizens have a right to an environment that is not detrimental to their health and wellbeing and to have the environment protected for present and future generations [
21].
Therefore, providing adequate waste management services is the responsibility of all spheres of government so that all citizens have access to basic services. Two types of national legislation, namely the Local Government: Municipal Systems Act [
22] and the National Environmental Management: Waste Act [
14], are relevant towards the realisation of this constitutional mandate. The Local Government: Municipal Systems Act [
22] maintains that municipalities must involve all local communities, whether urban or rural, through appropriate mechanisms, processes, and procedures; the goal being to achieve adequate performance management levels. The Act also compels municipalities to provide equitable access of waste management services to local communities in a financially and environmentally supportable approach [
22]. Furthermore, the National Environmental Management: Waste Act [
12] seeks to give effect to Section 24 of the South African Constitution, which makes provision for measures that aim to reduce the amount of wastes produced by human activities and also to ensure that such wastes are recovered, reused, and recycled in an environmentally friendly manner. As a result, local municipalities have executive authority in delivering services such as the removal, storage, transportation, and final disposal of municipal solid waste and they must comply with national and provincial standards. Some of these standards require the separation or segregation of municipal solid waste prior to collection, the proper management of landfill sites, as well as the prevention and control of littering. Municipalities must also provide containers that are accessible to the public for the collection of waste, including recyclable components [
12]. Despite these legislative provisions, waste minimization through separation at source, recovery, and recycling are not yet accorded a top priority in line with the new regulatory and legal requirements in South Africa [
13]. This shortcoming undermines the long-term goals of the zero-waste strategy, pollution prevention, sustainable solid waste management and ultimately sustainable development [
15].
To date, there is very limited empirical research [
23] on how local municipalities and communities in South Africa are responding to the new legislative and regulatory framework, which calls for integrated waste management, along with more public participation and increased waste recycling rates. Adopting an integrated waste management strategy means “integrated planning, implementation, monitoring, and review of these waste management measures to ensure sustainability and to prevent detrimental impacts on human health and the environment” [
24]. Unlike the majority of previous waste management studies in South Africa, which focussed more on cities and urban district municipalities [
23,
25,
26,
27], this paper is based on local municipal performance from the perspective of households in predominantly rural areas.
According to Gopaul [
28], South African rural areas are some of the poorest human settlements in the world, and they have limited access to employment and educational opportunities. Many of their communities live in severe poverty, squalor, and have limited development activities in terms of modern infrastructure such as telecommunications, water supply, roads, schools, industries and health facilities [
28,
29]. Consequently, their population structures are frequently skewed towards more women, as a larger proportion of job-seeking men are migrant workers in the cities and nearby towns, and even in other provinces such as the Western Cape and the Gauteng.
Very few scientific investigations [
29] have been directed to the challenges of rural solid waste management and its minimization, although nearly 40% of South Africa’s inhabitants still live in rural areas. Despite major historical impediments in the provision of effective municipal solid waste management in many areas of South Africa including large metropolitan municipalities, deep rural areas and many jurisdictions under traditional and tribal authorities face enormous challenges. Payments of municipal waste services by local inhabitants remain limited because most indigent households in these areas cannot afford such services due to high unemployment levels and rampant poverty [
30]. Sources of income and livelihoods in such rural areas are mostly scarce and are derived mostly from government social grants and pensions for the elderly, cash remittances from migrant workers, farm jobs, as well as subsistence agriculture, especially the rearing of livestock. It is for this reason that, in 2001, a national policy on free basic services was introduced specifically to provide a range of services to vulnerable households, including the poorest communities in rural areas [
30]. The national policy on basic refuse removal services also promote measures intended to educate and raise awareness levels within all municipalities regarding the proper handling of domestic solid waste as well as the need to minimize the generation of such waste through its recovery and recycling before being disposed of in landfill sites. For example, the collection rates of recyclable wastes in rural areas is expected to be at least once a month [
30], even though, in most instances, these areas are often without the necessary infrastructure and logistical support.
Given the paucity of scientific literature in South Africa on rural municipal solid waste challenges, the main aim of this paper was to assess the status and effectiveness of waste management practices through an understanding of the opinions and perceptions of community residents within the rural local municipalities in Umkhanyakude and Zululand Municipal Districts, both located in the KwaZulu-Natal province of South Africa. Although such community feedback provides only one side of the performance indicators of this municipal waste management system, such information can yield key insights in locating operational barriers and challenges. The study also established the degree of willingness or unwillingness amongst community residents to pay for improved municipal waste management services, the extent of waste separation at source, and the benefits and barriers associated with their participation in recycling initiatives.
3. Materials and Methods
3.1. Study Area
The geographical location of the study area is in the KwaZulu-Natal province of South Africa and is comprised of two district municipalities, namely, Umkhanyakude and Zululand (
Figure 1). In terms of population size, KwaZulu-Natal is the second largest (11.1 million) province in South Africa after the Gauteng province (13.4 million) [
49]. KwaZulu-Natal province has one metropolitan municipality, 10 district municipalities, collectively subdivided into 43 local municipalities [
49]. Although, all district municipalities in the KwaZulu-Natal province have both urban and rural areas, both Umkhanyakude and Zululand District Municipalities are predominantly rural in their land use patterns [
50] and were therefore suitable for the present research goal. Whereas Umkhanyakude District Municipality (UDM) has four local municipalities (Big 5 Hlabisa, Jozini, Mtubatuba, and Umhlabuyalingana), Zululand has five (Ulundi, Nongoma, Pongola, Abaqulusi, and Edumbe). Previous research conducted in these areas has mapped the location of illegal dumpsites, and has shown that the proportion of unpermitted disposal facilities is extremely high, with Zululand District Municipality (ZDM) having 83% whilst UDM had 89% [
50].
Similar under-resourced district municipalities such as Umkhanyakude and Zululand are found in other provinces in South Africa such as the Eastern Cape, Free State, Limpopo, North West, and the Northern Cape, and most of their rural areas have scattered or densely settled villages [
51]. Most of these areas have a communal land tenure system and to a lesser or larger extent, they are under the jurisdiction of traditional tribal chieftaincies. Rural municipalities (B4) in these districts are invariably characterised by the highest number of backlogs in basic municipal services such as electricity, water, sanitation, and refuse removal [
52].
3.1.1. Geographical Characteristics of the Umkhanyakude District Municipality (UDM)
The Umkhanyakude District Municipality (UDM) is located in the far northern region of the KwaZulu-Natal province and shares a border with Mozambique and Swaziland. This district has an area of approximately 13,855 km
2 with a population totalling 625,846 and 128,195 households [
52,
53]. The UDM forms part of the Lubombo Trans-Frontier Conservation area and is the second largest district in KwaZulu-Natal in terms of size, behind the neighbouring Zululand District Municipality [
53]. The UDM has a relatively small economy, contributing just 2.7% to the economy of the province [
52]. The economic activities of the district are mainly concentrated in two economic (trade) sectors, namely, agriculture and tourism. These two sectors together contribute 55% of the total economy of this district [
54]. However, educational and functional literacy levels as well as occupational skills levels are inherently very low [
52]. Thus, the UDM is one of the poorest municipalities, not only in the KwaZulu-Natal province but also in South Africa [
54]. Hence, it is one of the four district municipalities that are receiving presidential public funding from the Integrated Sustainable Rural Development Programme (ISRDP) in the province; the prime objectives being poverty alleviation, infrastructural development, as well as support for institutional and capacity development [
52,
54].
According to the 2014 Integrated Development Plan [
53], waste management has been a challenge throughout the UDM, with poor solid waste disposal posing a threat to human health and environmental components such as freshwater resources and the quality of ambient air. The provision of regular refuse removal services is limited to larger residential centers within this district. Only 10% of households [
53] were provided with weekly household refuse removal services compared to the overall provincial figure of 52%. Furthermore, approximately 96,089 households in the same district made use of their own refuse dumps (74%), with a further 15,989 households (13%) that are without any form of rubbish disposal sites [
53].
3.1.2. Geographical Characteristics of the Zululand District Municipality (ZDM)
The Zululand District Municipality (ZDM is also located in the far north of the KwaZulu-Natal province and borders Swaziland. This district has five local municipalities. In terms of governance, approximately 50% of the district area is allocated to traditional tribal authorities, while commercially owned farms and nature conservation areas constitute other important land-uses. The district covers an area of approximately 14,799 km
2, with a population totalling 803,575 and has nearly 157,748 households [
55]. The total percentage of urban households is only 25.4% while rural households make up 74.6% of the total population [
55,
56]. Given such a predominantly rural setting, this district is characterised by a high unemployment rate of 41%, which is higher than the overall provincial rate of 28.5% [
49,
55]. The local municipalities of Uphongola, Ulundi and Nongoma have the highest unemployment rates compared to other local municipalities within the district [
55]. However, the Abaqulusi Local Municipality has the highest number of households with employed inhabitants working predominantly in the agricultural farms within this area.
The most important towns are Vryheid and Ulundi, while Pongola and Paul Pietersburg constitute small service centres [
55]. According to ZDM [
56], economic investments in this district are generally small, thus not enough to enhance local economic development. Up to the late 1990s, the most important economic activity was coal mining, although its sphere of influence has declined markedly. During the 2011–2012 period, only 20% of households in the ZDM received formal waste disposal support functions, and this was predominantly restricted to urban areas [
56].
3.2. Questionnaire Survey Design and Methods
Scientific surveys entail finding relevant information on one or several groups relevant to the research problem and then asking pertinent questions on their characteristics regarding a phenomenon of interest [
57]. Surveys are usually quantitative in nature and aim to give a broad overview of a representative sample of a large population [
57,
58]. Primary data required for such studies are collected by questionnaires and can be summarized by means of descriptive and inferential statistics. Several empirical studies which investigated the role and perceptions of different stakeholders in municipal solid waste management systems and associated recycling aspects have made use of both qualitative and quantitative surveys [
10,
42,
59]. These surveys were undertaken by means of closed- and open-ended questionnaires. There are also different means of undertaking household surveys: “telephone interviews, postal surveys, (and) web-based survey(s)” etc. [
60].
In the present research, household surveys were undertaken by means of questionnaires that were administered during face-to-face interviews. These questionnaires had close-ended questions as well as Likert-type questions. Many studies on household waste management or recycling behavior have employed face-to-face questionnaire interviews mainly because of their high response rate although they can be expensive and time consuming [
58,
59,
60]. For the present study area, each questionnaire was comprised of the following sections:
Section A: Demographic aspects (jurisdictions, gender, employment status, level of education, and waste management functions);
Section B: Aspects of waste management and recycling practices (including for example, municipal solid waste collection rates, collection of solid waste and recyclables, current recycling practices, waste separation practices at source, and storage of recyclables), as well as the barriers and benefits associated with waste recycling were included.
Additional primary data to supplement close-ended questions was obtained by means of open-ended questions which were asked during the latter part of interviews. The key outcomes of this data gathering activity were photographed by means of cell phone cameras (iPhone 6 and Samsung A3).
3.3. Survey Procedures and Sampling Framework
This study followed a random sampling approach, whereby households in the two study districts had an equal chance of being included in the survey. The interviews were targeting mainly heads of households and if not present, available adults were consulted. Thus, respondents aged 20 years and below were not involved in the interviews. The surveys began with a small pilot study (with ~50 interviews), of which the purpose was to establish the suitability of the questionnaires for data collection prior to the main surveys. The pilot testing also assessed the time taken by respondents to complete the questionnaires. This testing also determined the level of support sampled community residents would need to answer questions effectively, especially as illiteracy levels were very high in the study area. In fact, questions which dealt with technical aspects such as waste sorting or separation at source, waste reuse and waste recycling, and the differences between these terms, and the frequencies at which some services are provided were asked by means of the local native isiZulu language, and where respondents did not understand explanations were provided.
Another important aspect of survey procedures involved compliance with ethical considerations. To achieve such compliance, the purpose of the surveys was firstly explained to the respondents adequately, and interviews only proceeded when respondents provided prior informed consent to the interviewers. In this way, respondents were made aware that they were not compelled to participate in these interviews, and that at any stage they can withdraw without any adverse consequences for their wellbeing and welfare.
Out of 400 community households that were consulted in the various local municipalities during the data collection period (August and October 2015), 333 residents were successfully interviewed. Given one respondent per household, the total response rate was 83%. Most of the respondents (60.7%; n = 202) were from the Umkhanyakude District Municipality whilst 39.3% (n = 131) of them were from Zululand. This discrepancy in the proportions of respondents interviewed per district municipality did not distort the results because all households are provided with the same municipal waste management services.
3.4. Statistical Data Processing and Analysis
The validity and reliability of the investigations was undertaken by using Cronbach’s alpha to verify whether the questionnaires were credible and internally consistent. The general agreed lower limit that was used was 0.7, while 0.6 was used as an acceptable level in the case where agreed lower limit of 0.7 could not be achieved. The reliability of questionnaires is depicted in
Table 1. All the major aspects or sections of the questionnaire met the minimum agreed level of 0.7, as proposed by Revelle and Zinbarg [
61]. The reliability of the overall instrument was found to be 0.824.
The primary data obtained from responses provided by interviewed community residents were processed into the Microsoft Excel (2010) programme and statistical analyses were carried out by means of SPSS version 24. Descriptive statistics in the form of tables, frequencies, and percentages were used to describe the patterns and trends in the data set.
5. Conclusions and Recommendations
In this survey, the current situation and effectiveness of waste management practices as well as the potential for increased waste recycling efforts in the rural areas of Umkhanyakude and Zululand District Municipalities in the KwaZulu-Natal province of South Africa has been assessed. This assessment was conducted from the viewpoint of community resident’s opinions and perceptions, making it one of the few baseline researches in the South African rural landscape. Given deficient educational backgrounds, high unemployment rates and meagre incomes amongst the respondents, especially in the light of recurrent economic recessions, it is difficult for inhabitants to cater for their own living expenses and household needs, let alone paying for municipal waste management services. Inevitably, there are high levels of dissatisfaction with local municipalities because more is expected from these institutions in terms of providing basic services, including regular waste collections and improved sanitation in the neighbourhoods. Another important constraint against effective waste management lies in the application of the free basic services policy that is earmarked for poor or indigent households in South Africa. The main problem with the implementation of this policy, not only in the studied district municipalities but everywhere in the low-income residential areas of South Africa, is the lack of criteria for differentiating between households that must be exempted from paying for waste management services and those that must pay even if set at a reduced nominal fee.
Progress towards integrated waste management is very limited in the surveyed areas because municipalities are more preoccupied with the need to increase the accessibility of waste management services to under-serviced rural communities rather than investing in the infrastructure for successful waste recycling programmes. This state of affairs is clearly defined in the various integrated development plans of these district municipalities, which seem to prioritize the need to address service backlogs without establishing institutional arrangements for increased waste recycling in the affected rural areas [
54,
55]. It is therefore not surprising to find a large proportion (96.7%) of respondents who are without relevant knowledge on how waste recycling can be practised at household level, along with the lack of waste sorting facilities or buy-back centres in close proximity to their homes. Inevitably, communities are expecting increased waste collection rates from the municipalities and very little towards the adoption of waste recycling and all the related mechanisms (i.e., waste separation, recovery, sorting, and reuse) that accompany its implementation.
As long as this status quo remains in these districts and there are no facilities for waste separation, the mixing of household solid wastes will continue unabated and recyclable waste will continue to be directed towards landfill sites for final disposal, thus undermining long term environmental sustainability.
Given the challenges local municipalities and residents are facing in the district municipalities surveyed, a number of recommendations are made. Firstly, there is a need for increased environmental awareness programmes at the district and municipal level so that residents acquire relevant knowledge for pro-environmental behaviour. As pointed out by Vicente and Reis [
68] “citizens who are better informed about recycling have a greater propensity to participate in recycling than those who are not so well informed”. Also, in several studies, it has been established that the supply of waste segregation and storage facilities are positively linked to increased community participation rates in recycling programs [
10,
67,
68,
69,
70]. Secondly, research on the composition and volumes of municipal solid waste is recommended along with determining amounts of recyclable wastes from the municipal waste streams.
