    Constraints to the implementation of public private partnerships for hydropower generation : the case of Uganda
    (2007) Emmanuel, Akampurira; Root, Dave; Shakantu, Winston
    In an environment of constrained public budgets and poor service delivery, private sector participation through Public Private Partnerships is increasingly being utilised as a vehicle to deliver public infrastructure. However, implementation is often problematic with varying degrees of success in different countries and sectors. To overcome a crippling power supply deficit, the government of Uganda is implementing strategies to encourage and incentivise private sector participation in the development of hydropower generation facilities. Notwithstanding the sector reforms and government commitment, private sector investment is still limited and many proposed projects have not materialised.

    Construction and demolition waste management : assessment of demand and supply of recycled materials in the Western Cape
    (2003) Delaware, Kamil; Shakantu, Winston
    Concern for environmental degradation has been a motivating factor in the efforts to reuse or recycle construction and demolition waste. The intention is not only to reduce environmental desecration, but also to recycle the construction and demolition waste into potential building materials to be reused elsewhere. This study investigated the supply and demand of recycled construction materials in the Western Cape, and aimed to determine the perception held by important stakeholders about these materials. A qualitative analysis of the case study results revealed that poor waste management plans implemented on construction and demolition sites have affected the quality, supply and price of recycled materials. In addition to this it was also revealed that the negative perceptions regarding recycled materials were the major barriers to creating an established secondary market. Inadequate knowledge and experience were major contributors to resistance to change of perceptions. A case study was conducted on Malans Quarries Recyclers in order to determine the supply of raw materials (construction and demolition waste) reaching the recycling plant; the supply of recycled materials to the end user (consumer); and the recycling process that takes place. A sample of fifteen respondents from a variety of large, medium and small construction contractors, as well as consultants and civil engineering companies, completed a questionnaire to determine the demand for and perceptions about these materials. The qualitative analysis of the results of the questionnaires showed that the majority of respondents still preferred to use primary materials over recycled materials. However, it appears that the gap between respondents who prefer to use primary materials, and those who utilize recycled materials, has narrowed in comparison to results obtained in previous studies. It seems that there may be more usage of recycled materials in the future. The results also revealed that tax cuts, could be a good economic incentive to encourage the use of recycled material. The questionnaire results also revealed that the majority of the respondents believed that landfill taxes where not effective in discouraging the illegal dumping of waste, and that the lack advertisements, and difficulties in obtaining recycled materials played a crucial role in the under-use of recycled materials.
