1. Introduction
Housing encompasses several concepts such as to include comfort, protection, and identity; it is essential to everyone’s wellbeing and quality of life wellbeing, with substantial socio-economic implications. It is an important part of every country’s social and economic structure. No country has yet satisfied itself that the different economic classes that make up its population have received sufficient housing. More than 100 million people are projected to be homeless, with another one billion living in substandard housing around the world. Even though they make up a quarter of the world’s population, only a small percentage of them live in developed countries [
1,
2]. The most serious housing challenges and shortages are observed in developing countries where homelessness affects about a third of the population. The reasons and nature of these challenges differ from one country to another, depending on the socioeconomic and political climate. Low-income countries’ housing problems are somewhat different from those of developed countries; even more, urban and rural housing peculiarities also exhibit their challenges [
3].
In Zambia, most urban dwellers in major cities live in squatter and unplanned settlements. As a result, the majority of city dwellers lack access to adequate housing and basic services, as well as other critical infrastructure such as roads and drainages. The underlying reason for this state of affairs is, among other reasons, due to lack of clear allocation of responsibilities among various players involved in housing development [
4]. The roles of the private sector and individual developers are not well-defined in the overall development process. A lack of common strategy in the form of a framework to harmonize the input of various key players in the industry is evident [
4]. This study sought to establish the measurement model for stakeholders’ participation in urban housing development for Lusaka, Zambia. The model is significant in outlining the roles of various actors in achieving improved urban housing.
2. Urban Housing Development in Zambia
The current national population for Zambia is estimated at 17.3 million people, with the housing stock at about 3.382 million. The housing deficit is estimated to be over 2.8 million [
5] and projected to exceed 3 million units by 2030, if no major interventions are taken [
6,
7]. The average housing units in urban areas across Zambia are estimated at 43%. In 2015, 53.5% of Zambian households were either traditional huts or improved traditional huts, of which 82.5% were in rural areas. Further, of the total housing units in urban areas, 64.9% use pit latrines facilities, either their own or shared. Likewise, with regard to electricity connectivity, the national access to electricity averages at 31%, with 67% of the urban and 4% of the rural population having access to power [
8]. Charcoal is still the most common source of energy for cooking and heating at 59.1% in urban households [
9].
Within urban Zambia, as in many other African countries, there are two systems: the formal city, which has complete infrastructure, and the informal city, which has little or no infrastructure and people coping as best they can [
10]. In Zambia, the urban growth has been taking place mostly in informal settlements, with the current housing stock being dominated by the informal units. Rural-urban migration trends in Zambia have led to high population growth in urban areas without corresponding improvements in housing and infrastructure for the provision of services. Provisions of urban infrastructure, such as roads, water, electricity, and sanitation, are an important component in the construction of the urban built environment in any city [
11].
Historically, the government of Zambia has supported housing markets and development by providing urban infrastructure. By the 1980s, however, the state of infrastructure in many cities and towns had deteriorated to the point where local governments were no longer able to provide these essential services [
12]. The private and informal sector arose to fill the void, created by the absence of state and local government provisions of housing and urban infrastructure [
11].
The change of government in 1991 resulted in a shift in thinking about how the economy should be managed. The economy was liberalized and, in order to boost the housing sector, the government thought it was important to have a clear plan to look at the provisions of infrastructure, such as highways, water, street lighting, and sanitation, when formulating the National Housing Policy. Nonetheless, the condition did not significantly change over time. This was due to a lack of funds, repairs, and infrastructure refurbishment or replacement. Munshifwa [
11] noted that the country has seen the refurbishment of urban roads in recent years, especially in old municipal townships, with the help of borrowed funds. However, he argues that there has been little progress in opening up new residential areas or upgrading informal settlements. In 2016, the Committee on Local Governance attributed lack of access to housing finance, low number of public private partnerships (PPPs), as well as low government investment in housing development to be among the factors contributing to poor urban housing in Zambia.
3. Neo-Liberalism in Housing Development
Neo-liberalism is generally viewed as an economic ideology aimed at limiting the scope of government. It is a way of governing that is taken up in different ways by different regimes, that is, as a political economic practice which contends that allowing individuals to exercise their entrepreneur liberties and abilities within an established framework marked by strong private property rights and liberalized markets, as well as free trade, is the best way to advance human well-being [
13]. Garcia [
14], p. 3, adds that “the role of the state is to create and preserve an institutional framework appropriate to such practices. More so, that if markets do not exist (in areas such as land, water, education, health care, social security, or environmental pollution) then they must be created, by state action if necessary. But beyond these tasks the state should not venture”.
Since the 1980s, neo-liberalism has dominated policy development and implementation, and it has had a major effect on the reshaping of urban housing delivery in various countries improving on urban housing [
15]. Cognizance is taken of the fact that the state alone cannot manage to provide housing for all due to the limited financial resources against many conflicting needs, thereby, underscoring the need for private sector participation [
16]. However, this has not been without any challenges; for instance, according to Taruvinga and Mooya [
17], p. 136, “problems are likely to abound in adopting a neo-liberal housing policy in the low-income sector, chief amongst which is very low incomes among the targeted group to sustain mortgage finance. Volatile economies with high inflation, economic recessions and lack of primary mortgage instruments contribute towards hurdles in implementing a neo-liberal housing policy”. They added that, while neo-liberalism has progressed in making housing markets more functional, it also has the potential to alienate low-income earners from market participation if effective policy positions are not taken. Taruvinga and Mooya [
17] further pointed out that neo-liberalism is not uniform; therefore, its implementation must take into considerations the prevailing local, macro-economic, and environmental factors.
In Zambia, currently, the national policy direction on housing, among other thrusts, is aimed at ensuring inclusivity (participation) and partnerships among stakeholders in achieving affordable and decent housing for all. It is premised on the principles of a free market economy (neoliberalism).
4. Stakeholders Participation
The complexity and multidimensionality of urban areas require multi-sectorial development approach, according to Majale [
18], adding that single-sector interventions cannot sustainably improve the housing condition of the urban dwellers. Ochunga and Awiti [
19] established that there is a significant positive correlation between optimum participation among stakeholders and sustainability of development. Aigbavboa and Thwala [
20] posit that success of development is dependent upon the participation of beneficiaries and stakeholders. Participation of the state, private sector, and community have been identified to have positive impacts on housing delivery. Stakeholder participation is critical in attainment of desired urban housing development. Eisenbeiß [
21] and Connective Cities [
22] opined that in the creation and implementation of strategies for urban development, a diverse range of actors from the private sector, civil society organizations, and the government are required. Hence, in this study, stakeholder’s participation refers to the involvement and contribution of interested or concerned parties, which include the state either directly or through its institutions; the private sector, such as developers and financial institutions; non-governmental organizations; the community or individuals in urban housing development.
Selection of Indicator Variables for Stakeholder Participation
Literature review on housing studies revealed that most housing development models are in sync with the neo-liberal perspective of housing delivery, which postulates that housing provisions should not be left to the state alone, but rather require involvement of other stakeholders. Furthermore, it states that the state should participate by providing basic services as well as creating an enabling environment for housing development. Literature evidence revealed stakeholders’ participation as an essential recipe for housing development, among other variables.
The selection of indicator variable for the construct of stakeholders’ participation was informed by similar housing studies [
18,
23,
24,
25,
26,
27,
28,
29]. In a conceptual framework for urban housing for all, among the key determinant factors identified by Tiwari et al. [
28] were private and state participation. Similarly, Amado et al. [
29] outlined public sector participation, private sector participation, community participation, and stakeholder partnerships to be important factors in integrated urban regeneration strategy. Ramovha [
30] identified private sector participation, state participation, and community participation. Likewise, in a pluralistic conceptual model for affordable housing by Ogunnaike et al. [
26] key determinants were identified; these included private sector as well as state participation. Lastly, Majale [
18] identified critical factors in an integrated approach to urban housing development; these included private, state, community, and NGOs’ partnership, among other factors. The detailed breakdown of the indicator variables for the construct of stakeholders’ participation is as shown in
Table 1.
5. Materials and Methods
This study adopted a quantitative approach with data collected using a structured questionnaire, with a 5-point Likert scale. A structured questionnaire containing 25 indicator variables identified from literature was administered to a total of 214 respondents drawn from several key institutions involved in housing development and planning. These included government ministries, non-governmental organizations, private property developers, mortgage lending institutions, quasi-government institutions, and consultancy firms, as well as other housing-allied professions, as shown in
Table 2. Literature evidence generally suggests having a minimum of 200 respondents for a study employing structural equation modeling [
31,
32,
33,
34,
35].
The academic qualifications of the respondents were mainly in built environment programs and other housing-aligned fields. These included urban and regional planners (n = 39; 18.0%), architects (n = 40; 19.0%), quantity surveyors (n = 65; 30%), real estate/property valuers (n = 51; 24.0%), and other professionals (n = 18; 8.0%). However, one respondent did not indicate the professional qualification. Lusaka, which is the capital city of Zambia, was chosen because nearly 70 percent of all its housing stock is substandard and informal: a situation similar to many cities in the sub-Saharan African countries, hence making it more relevant for the study.
Collected data were analyzed in two stages; the first stage involved an exploratory factor analysis (EFA), while the second stage was a confirmatory factor analysis (CFA). EFA was used as a preliminary phase (first stage) to investigate the nature of the latent construct of stakeholders’ participation and gain an understanding of the relationships between the measured indicator variables and the corresponding latent factor (construct). Exploratory factor analysis is useful in the initial phases of development because it demonstrates how well items load on a non-hypothesized factor [
36]. Its aim is to determine the optimal number of factors and to reveal whether there are reasonable indicators for various potential aspects of measured items (variables) [
37,
38]. However, the main objective of confirmatory factor analysis was to investigate whether the data fit the hypothesized measurement model which is based on a certain theory [
39], in this case, the neo-liberal theoretical perspective.
7. Discussion
The results of the CFA displayed that the interfactor correlations and the standardized factor values for the latent factor, stakeholder’s participation, were significant statistically, indicating a high level of linear correlation between the indicator variables and the construct (stakeholders’ participation). The scores were equally significant when the total variances accounted for by the variable in each test were examined. Profoundly, the results of this study inform that the stakeholders’ participation model is defined by seven variables, namely: private sector participation in the provision of affordable housing finance; private sector participation through construction of rent-to-buy housing; private sector participation through partnering in the provision of basic services; community participation in the develop of housing programs; the state facilitating access to affordable housing finance; the state stimulating private sector involvement in affordable housing provision; NGOs’ participation by coordinating the communities. Moreover, the findings indicate that all the variables retained in the model have a substantial influence on the development of urban housing, and the results generally agree with previous studies [
17,
26,
62,
63,
64]. The consideration of the combined effect of the seven variables that define the construct, stakeholders’ participation, from the neoliberal perspective in this study, are peculiar relative to other housing studies.
Furthermore, among the seven variables, private sector participation in the provision of affordable housing finance is the leading variable contributing to the construct, stakeholders’ participation, having recorded a standardized coefficient value of 0.785. This result supports the assertion by the International Finance Corporation [
62] that the private sector should participate by offering solutions in financing and innovative tenure models. Additionally, with regard to private sector participation, Morakinyo et al. [
63] posit that the private sector has a role to play in the provision of housing by constructing houses for all classes of the population, either for renting out or for sales, as well as in the development of other critical infrastructure needed for human settlements. The International Finance Corporation [
62] further adds that the private sector should participates by providing essential services such as transport, telecommunications, and water, as well as power, adding that these services are important to growth and improving people’s lives. Another way in which the private sector should participate is through public-private partnerships (PPPs). Literature evidence points out that public-private partnership is needed to resolve urban housing shortages, with the government’s position in the partnership—consisting of providing land and basic services such as roads, power, and a regulatory system, as well as conducting the procedure of obtaining permits, authorizing housing development plans, and registering land titles—being simpler. On the other hand, the private sector should participate in the actual development, financing, and manning of housing projects [
26,
65,
66].
With regard to state participation, the results agree with literature, as well as the theory, that the state should play a significant role in facilitating housing development. As an enabler, the state should provide the necessary support base and stimulate optimum involvement of other actors in the housing development process. The state actualizes this by facilitating easier access to finance, as well as removal of restrictive legislation [
26], and thereby stimulating private sector involvement in affordable housing provision. This further agrees with Taruvinga and Mooya [
17], who posited that in order to encourage and stimulate private sector participation, the state needs to create an enabling environment and a suitable regulatory environment for housing development. A view is shared by other authors that it is the role of the state to protect and create prospects for the private sector involvement in the housing property market [
16,
64,
66]. Though, Harvey [
67] earlier argued that “whilst acknowledging the role of the state in enabling markets to work, it is important that state intervention be kept at a bare minimum because powerful interests can inevitably distort and bias state interventions for their own benefit”.
Similarly, on community participation in housing development, the results agree with literature evidence that as stakeholders in the housing sector, community members must participate in consultations and negotiations in order to make realistic decisions concerning their housing needs. The value of community engagement as consumers in the delivery of housing has been emphasized in many studies [
68,
69,
70]. Community participation is a critical ingredient to housing development. “Community participation is understood in terms of the role of the target group and local organisations in design, implementation, maintenance and evaluation” [
71,
72]. Community involvement in decision making on the design of housing, as well as allocation of construction sites, is valuable in the development process [
71,
73,
74,
75]. Khan, Haupt [
76], and Ellinger et al. [
77] reaffirmed it by positing that the right to adequate housing contains entitlements, which include participation in housing-related decision making at the national and community levels.
On the other hand, the variable of NGOs’ participation by coordinating the communities contributed least to the construct of stakeholders’ participation, having recorded a standardized coefficient value of 0.608. Similarly, the finding agrees with literature; Keivani and Werna [
78] posit that NGOs can aid squatter, as well as unplanned settlement dwellers, by assisting them in the establishment of appropriate community groups and mobilization, as well as providing technical and organizational expertise for self-help house construction. Pugh [
79] holds that NGOs provide valuable links between communities and the state. The World Economic Forum [
80] adds that NGOs “have a critical role in bridging the gap between governments and the private sector to improve the affordability of housing, as well as working with individuals to help them understand their options and make informed decisions”. Rahman [
81] posits that if the poor are able to decide about their own needs, affordability, and goals, they will be able to share responsibility. NGOs, they argue, foster pluralism by including them in consultation, planning, decision making, and housing program implementation. Satterthwaite [
82] shares the viewpoint by holding that “NGOs are significant because they partner with urban poor households and their community organisations and networks to increase their voice”.
8. Conclusions
Anchored on neoliberalism, this study identifies the factors which predict stakeholder participation in urban housing development from a developing country’s perspective. Using Lusaka as a case study, the results affirm that stakeholders’ participation in urban housing development can be measured and enhanced by ensuring stakeholders participation through: private sector participation in the provision of affordable housing finance; private sector participation through construction of rent-to-buy housing; private sector participation through partnering in the provision of basic services; community participation in the develop of housing programs; the state facilitating access to affordable housing finance; the state stimulating private sector involvement in affordable housing provision, as well as NGOs’ participation by coordinating the communities.
Further, this study highlights the roles of various actors, namely the state, private sector, and non-governmental organizations, as well as the community in urban housing development. Recognizing that it is difficult for the state to provide housing for all citizens, the neoliberal perspective as espoused in this study outlines how the state can bring in other actors, to participate in the provisioning of affordable urban housing by creating an enabling environment for investment/partnerships.
However, it is important to note that, though interesting and valuable findings have emerged from this study, it is not without limitations. The study targeted respondents who had academic qualifications mainly allied to the built environment, drawn from several institutions involved in housing development and planning. A study that includes other relevant stakeholders such as the community members could be conducted.
