Factors Influencing Intention to Adopt Solar Energy Solutions in Households in Zambia: Insights from the Theory of Planned Behaviour

Purpose – This study examined the factors that influence households' intention to adopt solar energy solutions in Zambia. This, in view of low adoption rates of solar energy solutions even in the wake of a widespread electricity power generation deficit across sub-Sahara Africa (SSA) has plagued the region with daily electricity load shedding lasting several hours at a time. Given the vast potential for solar energy generation in the region, solar energy solutions have become an attractive option to grid-based electricity, and many households have intentions of adopting these solutions. Methodology – Through the lens of the theory of planned behaviour (TPB), the study surveyed adult household members in Zambia who contributed towards the household's income. The participants were selected using the snowballing technique which yielded a sample of 961 respondents. The results were analysed using structural equation modelling. Results – The results show that attitude, trust, benefits and subjective norms influence the intention to adopt solar energy solutions. Trust and benefits also influence the intention to adopt solar energy solutions indirectly through attitude. Therefore, measures aimed at increasing the adoption of solar energy solutions should focus on improving the attitude, perceived benefits, trust in the solutions and consider subjective norms. Originality – The findings add to the understanding of the factors that influence the intention to adopt solar energy solutions in Zambia. Therefore, the findings can be used to inform measures aimed at improving solar energy uptake in Zambia. The study also reports on the previously unreported mediating role of attitude towards solar energy solution on the associations between perceived benefits and trust with solar energy solutions adoption intention

Sustainability awareness and practices in the Zambian construction industry

The construction industry makes a significant contribution to the global green-house gas emission. It is, therefore, critical that construction industry professionals should be aware of and practise sustainable construction. However, there is a paucity of studies on the awareness of sustainability and their practices in developing countries, with some results seemingly contradicting. This article explored the awareness and practices of sustainability in the Zambian construction industry. Data was collected from construction industry professionals through a questionnaire survey and a total of 112 responses were received. The relative importance index (RII) and a series of linear regression analyses were used to analyse the data. The participants’ perception of sustainability was primarily enviro-centric as opposed to the economic or social context. However, social and economic sustainability practices ranked highest, while environmental sustainability practices ranked in the bottom five of the 16 practices. While the participants perceived the environmental context as more critical in their understanding of sustainability, their practice reflected a focus on the social and economic sustainability context. The findings imply that merely increasing the level of knowledge and awareness of environmental sustainability may not lead to gross improvements in environmental sustainability practices. Therefore, studies that recommended increasing knowledge and awareness, in order to increase the implementation of environmentally sustainable construction, may have neglected the effect of the other barriers to sustainable construction which may be more critical. Studies with multivariate analyses such as structural equation modelling are needed to establish the contributory effect of the various barriers to environmental sustainability practices and so establish the extent to which knowledge and awareness alone, and other factors, can improve environmental sustainability practices

Drivers and barriers to Sustainability practices in the Zambian Construction Industry

Zambia, and Sub-Sahara Africa (SSA) generally, is lagging behind in the area of sustainable construction due to several barriers to the implementation of sustainable construction. This study therefore explored drivers and barriers to the adoption of sustainable construction practices in Zambia. The study could inform stakeholders on measures which could improve the implementation of sustainable construction. The study used an online quantitative questionnaire survey of construction professionals and clients. A total of 112 responses were received representing various stakeholder groups in the construction industry. The data were subjected to factor analysis and ranked using the relative importance index. The data show that drivers to sustainable construction cluster into three constructs namely, environment and health-related factors, regulatory and industry-related factors and, economy and firm related factors. Barriers clustered into three groups namely, awareness and knowledge related factors, regulatory and industry-related factors and, economy and cost-related factors. Therefore, measures aimed at improving sustainable construction in Zambia should focus attention on these broad clusters

Clinical and ultrasonographic features of abdominal tuberculosis in HIV positive adults in Zambia

Background: The diagnosis of abdominal tuberculosis (TB) is difficult, especially so in health care facilities in developing countries where laparoscopy and colonoscopy are rarely available. There is little information on abdominal TB in HIV infection. We estimated the prevalence and clinical features of abdominal (excluding genitourinary) TB in HIV infected adults attending the University Teaching Hospital, Zambia. Methods: We screened 5,609 medical inpatients, and those with fever, weight loss, and clinical features suggestive of abdominal pathology were evaluated further. A clinical algorithm was used to specify definitive investigations including laparoscopy or colonoscopy, with culture of biopsies and other samples. Results: Of 140 HIV seropositive patients with these features, 31 patients underwent full evaluation and 22 (71%) had definite or probable abdominal TB. The commonest presenting abdominal features were ascites and persistent tenderness. The commonest ultrasound findings were ascites, para-aortic lymphadenopathy (over 1 cm in size), and hepatomegaly. Abdominal TB was associated with CD4 cell counts over a wide range though 76% had CD4 counts <100 cells/μL. Conclusion: The clinical manifestations of abdominal TB in our HIV-infected patients resembled the well-established pattern in HIV-uninfected adults. Patients with fever, weight loss, abdominal tenderness, abdominal lymphadenopathy, ascites and/or hepatomegaly in Zambia have a high probability of abdominal TB, irrespective of CD4 cell count. © 2009 Sinkala et al; licensee BioMed Central Ltd

Infrastructure Design Stage Considerations for Environmental Sustainability in Zambia

While previous studies have highlighted the importance of incorporating environmental sustainability in building designs, there is a paucity of studies which assess the extent to which design teams in developing countries consider environmental sustainability at the building design stage. Therefore, using Zambia as a case study, this study examined the extent to which infrastructure design teams in a developing country consider environmental sustainability at the design stage. The study employed a qualitative research approach using structured interviews because there are hardly any studies which have explored the extent to which designers incorporate environmental sustainability in infrastructure designs in developing countries. The data were analysed thematically using the ATLAS.ti software. The results show that environmental sustainability is not an important design consideration because it is secondary to functional, technical and aesthetic considerations. Environmental considerations are also made in an ad-hoc manner and when it is cost effective for the project. Regulatory requirements pertaining to environmental protection are adhered to without any cost considerations. It was therefore theorised that building design teams in developing countries make technical, functional and aesthetic consideration during the infrastructure design stage ahead of environmental considerations. There is a paucity of studies that have investigated whether building infrastructure designers consider issues of environmental sustainability at the design stage in developing countries. The findings have practical implications on how developing countries can foster environmental sustainability at the design stage and avoid generating a building infrastructure stock that will require environmental resilience adaptation in the future

Challenges, drivers and incentives to private sector participation in public-private partnership projects in developing countries: evidence from Zambia

Purpose Governments in developing countries seeking to meet their infrastructure backlog are increasingly turning to public–private partnerships (PPP) due to a lack of public funds. However, while there are factors which drive the current uptake of projects, there are challenges with attracting private finance, and it is not clear what incentives can be used to attract more private participation, especially in sub-Saharan Africa (SSA). Therefore, this study aims to examine challenges, drivers and incentives that affect private participation in PPP projects in Zambia. Design/methodology/approach The study used a qualitative approach with semi-structured interviews with participants who had first-hand experience working on the administration of PPP projects. The participants were predominantly from the public sector, and so the results are largely a public sector perspective on the matter. Findings The findings show that bureaucracy and a poor business environment emanating from poor policies, long procedures and a poor economic environment are the main challenges affecting PPP projects. The current demand for the projects is being driven by a stable business and economic environment while incentives include enhancing the business environment by improving procedures and policies. Originality/value The study contributes to extant literature by proposing an overarching theory about the challenges affecting the implementation of PPP projects in Zambia, in particular, and in SSA, in general. The results show areas where governments and government agencies responsible for PPP projects can focus attention to promote private participation

Challenges and advocated solutions for environmental protection legislation for building infrastructure projects in developing countries: Evidence from Zambia

Environment protection legislation is often inadequate and poorly implemented in Africa even though literature shows that it is important for environmental protection. Furthermore, there is a paucity of studies which examine the catalytic role of legislation in the building infrastructure sustainability agenda. Therefore, to bridge that knowledge gap, this study examined the adequacy of environment protection legislation for building infrastructure projects in Zambia and their associated challenges and solutions. The study used an exploratory qualitative approach using semi-structured interviews with key stakeholders on environment protection. The study theorises that environment protection legislation in Zambia is fairly adequate but with inadequacies in its implementation, some with omitted content, and poor understanding of the importance of environment protection. Solutions include increasing the level of implementation of the legislation and championing awareness of the importance of protecting the environment. The findings have implications for sustainability transitioning in Africa

An appraisal of the indigenous chicken market in Tanzania and Zambia. Are the markets ready for improved outputs from village production systems?

Traditional or village poultry, consisting primarily of indigenous chickens, make up over 80% of poultry in Africa. Most are kept as small flocks in free-ranging, scavenging, low input production systems. They provide vital nutritional and financial needs especially for children, women of reproductive age, people with HIV/AIDS and the poor. Poultry meat and eggs provide animal source protein and essential micronutrients which improves growth and cognitive development in children. While productivity of indigenous chickens is low due to uncontrolled disease and an unreliable scavenging resource base, the minimal inputs result in a high benefit-cost ratio. By increasing supplementary feeding through improved crop yields and improving disease control through vaccination, a higher number of chickens of greater bodyweight will be available to market. An appraisal of the indigenous chicken market in Tanzania and Zambia was conducted to identify the key individuals (including gender imbalances), market channels, commercialisation margins, market trends and competition from exotic, commercial chickens (broilers and spent layers). Consumers preferred indigenous chickens and urban consumers paid their significantly higher price, which resulted from the accumulative costs of intermediary traders’ fees, transport costs and market fees. Commercial chickens in urban markets sold at a lower price but were vulnerable to fluctuating costs of high inputs. Indigenous chicken producers’ margins were favourable enough to suggest that some additional costs were sustainable, provided the off take channels and consumer confidence is sustained. Markets for indigenous chickens were informal and consequently, their response to increased production may be unpredictable

Sustainable Facilities Management Practices in Selected Universities in Ado-Odo/Ota Local Government Area, Ogun State, Nigeria

&nbsp;Sustainable development is being pursued at a global level and acknowledged across all sectors of the economy including universities. In order to apply sustainable measures, universities need to be vigilant in their management approaches. This study aimed at assessing the extent to which the selected universities in Ado-Oda/Ota Local Government Area of Ogun State have incorporated sustainability principles into their facility management practices. The study adopted a qualitative case study approach where interviews were conducted with experts from Covenant University (CU) and Bells University of Technology (BUT) who were purposefully sampled. The study population was comprised of facility managers from the physical planning and development units of the two universities who were chosen because of their expertise and responsibility. The interview guide contained questions about the types of buildings in the universities, sustainable facilities management (SFM) strategies being used by the universities, factors influencing the adoption of SFM strategies at the universities and challenges to the adoption of SFM practices. Data was analysed using conventional content approach. The study found that the universities have partially implemented SFM practices. The common practice adopted by the universities includes energy management. The universities have also done well in waste management. Legislation and cost savings were the drivers for the adoption of SFM practices. Despite such being the case, there are challenges to the adoption and implementation of SFM. These include resource constraints, design constraints, and lack of knowledge about SFM. Therefore, the study recommends development of a system that monitors and evaluates progress of sustainable facilities management practices in the Universities in Ado-Odo/Ota LGA, Ogun State
