    Performance Based Water Loss Management for Gweru, Zimbabwe
    (2017) Makaya, E.
    Different water utilities use different performance indicators to assess their performance. Although these indicators are peculiar to particular situations, it is paramount that each indicator is applied consistently among utilities as this is good for benchmarking purposes. Besides being well documented, performance indicators have not been well reviewed from the perspective of developing countries. Furthermore, there is limited understanding of the application of performance indicators among developing countries. Therefore this paper reviewed performance indicators for physical water loss management. The African Development Bank self-assessment matrix was applied to the City of Gweru, Zimbabwe. Furthermore, the infrastructure leakage index was used to assess the performance of the water utility. The self-assessment approach showed a 62% level of implementation of NRW strategies by the city. This means that the city was poorly managing its non-revenue water. The city had an infrastructure leakage index of 9.7. This index is in Category C of the International Water Association physical loss matrix meaning that the city was managing its non-revenue water poorly. Therefore the city must be proactive in the management of its physical water losses as well as maintain its infrastructure consistently.

    Research Funding Needs for African Engineers: Challenges and Perceptions
    (2017) Makaya, E.
    Africa and sub-Saharan Africa in particular, with the exception of South Africa, have lately lagged behind in postgraduate research, an issue attributed to lack of research funding for engineering sciences. This paper investigated the funding needs of engineering sciences in Africa. Specifically, it established the funding needs of African engineering sciences, factors affecting higher learning institutions in securing research funding and assessed the prevalent engineering research needs for Africa. Key informants to this paper were postdoctoral candidates drawn from Cameroon, Ethiopia, Ivory Coast, Kenya, Nigeria, Tanzania, Uganda and Zimbabwe. Through a questionnaire survey, the study found out that Africa has the capacity to carry out high profile engineering researches but the funding needs are not fully met resulting in frustration, whose ripple effects culminate in brain drain. Institutional frameworks in many African countries have been found not favouring engineering sciences. Although efforts are being made, as evidenced by increase in scientific publications, the growth of Engineering Sciences lags behind other disciplines. Thus, the international community of research funders should forge partnerships and collaborations with engineering institutions in Africa for availing and putting to good use research funding.
