Ronald Sungu Obtains a PhD In Environmental and Water Sciences

Dr. Ronald Sungu has graduated with a PhD in Environmental and Water Sciences from the University of the Western Cape – Cape Town, South Africa. Dr. Sungu holds a Masters Degree in Hydrology and Water Resources Engineering from Kenyatta University.

Dr. Sungu has been instrumental in both academics and other areas. He is remembered for initiating Certificate Programmes in Fire Engineering and Basic Draughtsmanship, Starting HIV and counselling programmes at the then Kenya Polytechnic, as well as ‘The Culture week’ (Culture for moral rearmament) activities.

Dr. Sungu served this institution as the chapter chairman of the Universities’ Academic Staff Union (UASU) from 2009 to 2016. He led the negotiations which culminated in signing of the first chapter CBA and is currently the chapter trustee. Dr. Sungu is currently finalising a research paper.

Here is his PhD thesis briefly outlined;

An assessment of the influence of water allocation on sustainable water resources management: a case study of the Nyando River Basin, Kenya

Several river basins in the sub-Saharan region experience water resources management problems. For example, water problems prevalent in the Nyando River Basin are due to an ineffective water allocation system and lack of adequate conditions for implementation of sustainable integrated water resources management (IWRM) strategies. The basin is bedevilled by poor water resources management, inequitable allocation of water among consumers, physical infrastructural deficiencies, inefficient water utilisation, illegal water abstractions, natural resource mismanagement, conflicting and weak institutional roles and lack of stakeholder involvement in water resource management. Water legislation in Kenya and elsewhere embraces integrated water resources management principles which should lead to elimination of these problems.

The results have further revealed sufficient per capita annual water availability with the potential to realise both Sustainable Development Goals (SDGs) and the Kenyan Vision 2030. However, analyses from flow duration curves (FDCs) and the water evaluation and planning (WEAP) model show that monthly water demands including environmental flow requirements (EFRs) are only partly met. While the Water Act (2002) upholds the principles of IWRM on equitable and sustainable water resources allocation, in practice the current water allocation system falls short of implementing these strategies due to lack of a water allocation plan (WAP), inadequate water demand management (WDM), low infrastructural development and lack of community participation in WRM. For example, the total revenue generated in water supply schemes is only about 25 to 30% of their operational costs, which means that in the absence of subsidies the schemes cannot operate. The goal of this study was to examine the influence of the current water allocation system on water resources management in the Nyando River Basin by comparing the various sectoral water demands in the basin with the available water resources in order to improve understanding of how water allocation systems work in practice. The analyses further revealed that irrigation uses up to 72% of the available water, which is mainly drawn from the regular low flow contrary to the permit order. For example, the Ahero National Irrigation Scheme is permitted to draw 47 m3/day of water from regular flow and 13,500 m3/day from flood flow, but draws the whole amount from the regular flow; hence irrigation is the main cause of water deficits in the basin. Projections show that the irrigation sector will experience 300% increase in an unmet demand of 92.4 Mm3 by 2030 up from the current annual deficit of 2.9 Mm3. In light of the above challenges, both improvement of WDM and infrastructural provision have complementary roles in contributing to sustainable water availability, socioeconomic growth and poverty eradication in the basin and help achieve SDGs at the local scale. The results of the study will facilitate an understanding of the influence of water allocation systems on regional hydrology and form the basis of improving water allocation systems, and inform policy formulations to ensure sustained water availability and environmental sustainability in river basins. In that regard, this study contributes to the on-going global debate on Sustainable Development Goals by exploring ways of realising and improving IWRM strategies and the National targets.
