Researcher probes into military presence in politics - Dr Hlengiwe Dlamini
Dr Hlengiwe Dlamini, a postdoctoral Fellow at the International Studies Group at UFS questions the nature of Zimbabwe’s leadership change in her research.

Was Zimbabwe’s leadership transition in 2017 a classical coup d’état, an unconstitutional change of government or a legal political process? Dr Hlengiwe Portia Dlamini, a postdoctoral Fellow at the University of the Free State’s International Studies Group (ISG), employed this contentious question as the backdrop to her paper titled: “The Paradoxes of Accepting/Rejecting and Constitutionalising/unconstitutionalising the 2017 Zimbabwe coup d’état through the Prism of the Organisation of African Unity and African Union Framework.” She presented her findings at the Stanley Trapido seminar held on 9 April 2018 at the Bloemfontein Campus.

Zimbabwe’s military facilitated the removal of former President Robert Mugabe from power after a 37-year rule. Dr Dlamini’s stance is that the events of 14 November 2017 were a trailblazer for a new form in coup across the globe. In veering from conventional coup elements and adapting alternative terminology in reference to overthrowing Mugabe, Zimbabwe’s military has set the pace for the rest of the world as far as the intertwining of military and politics is concerned.

Remembering 14 November

On the evening of 14 November 2017 the Zimbabwe defence force gathered around the country’s capital, Harare, and seized control of the Zimbabwe Broadcasting Corporation and other key areas of the city. A day later the situation escalated when military spokesman Major General Sibusiso Moyo addressed the citizens via television assuring them there was no military takeover of the government. 

Mugabe’s resignation was announced on 24 November 2017 following a motion of impeachment and a vote of no confidence reinforced by a joint session of parliament and the senate as well as the ruling Zanu–PF party. 

Military and politics intersections
According to Dr Dlamini, Zimbabwe High Court Judge, retired Brigadier General George Chiweshe, justified the military intervention in November 2017 as legal, thereby setting a dangerous precedent for political change in Africa.  

Prompted by the premise that the military overthrow of governments is no longer treated as a domestic issue in the post-cold war era, Dr Dlamini argues that it has become the business of the African Union and donor organisations to intervene and stop coups when they threaten. This explains why, according to Dr Dlamini, the Zimbabwe military establishment struggled to conceal the removal of Robert Mugabe from power as a coup for fear of attracting the wrath of the African Union and other organisations. 

Whether Zimbabwe’s crisis was merely a military response to a popular call by disgruntled citizens or a coup is left to contextual interpretation.

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
