According to Dr Munita Dunn-Coetzee, it is increasingly recognised that females with ADHD portray a different ‘picture’ in terms of behaviour, symptoms, and comorbidities when compared to males with ADHD.

I’m a failure as an adult. I’m a disappointment as a colleague. I’m a lousy friend. I’m a burden as a wife. I’m a bad mom and I’m constantly scrambling to try and hide it.

This is the secret interior reality of a group of neurodivergent adults who have been long overlooked by scientists and doctors alike. The Lost Generation. It is now recognised that there is an entire generation of women out there who have battled with ADHD (attention-deficit hyperactivity disorder) their entire lives – and don’t know it.

Women and girls living with ADHD

For decades, ADHD has been predominantly associated with hyperactive young boys bouncing off the walls. The reason for this widely-held misconception is due to the fact that studies originally focused on young European American boys – their symptoms becoming the benchmark for all. Women were not even included in ADHD studies until the late 1990s, and the first long-term study on girls was only conducted in 2002. The results? Girls’ ADHD symptoms bear little resemblance to those of boys. Dr Munita Dunn-Coetzee, Director of Student Counselling and Development at the UFS, agrees. “It is increasingly recognised that females with ADHD portray a different ‘picture’ in terms of behaviour, symptoms, and comorbidities when compared to males with ADHD. Females are less likely to be identified and referred for assessment, and their needs are less likely to be met.” Therefore, the majority of girls and women with ADHD remain un- or misdiagnosed.

But what does ADHD in women look like? First, let’s take a step back. There are three types of ADHD: the hyperactive type, the inattentive type, and the combined type – which includes both hyperactivity and inattention. Hyperactivity in females is much more likely to present internally, in the mind, and inattentiveness as daydreaming and disorganisation. This is much more than sitting still in class or having trouble with homework. Faced with behavioural and social pressures to perform, girls often learn to mask and overcompensate for their problems – making diagnosis even more difficult.

Carry the struggle to adulthood

When left untreated, girls with ADHD will most likely carry their struggle into adulthood. ADHD in adult women often results in chronic low self-esteem, self-loathing, feelings of inadequacy, sleeplessness, anxiety, depression, substance abuse, and eating disorders. Women with ADHD also typically present with tremendous time management challenges, chronic overwhelm, and exhaustion – exacerbated by societal pressures. The risk of self-harm and suicide attempts is also startlingly higher compared to their male counterparts.

There is tremendous hope, though. Drs Edward Hallowell and John Ratey – experts in the field who both have ADHD – describe ADHD as an array of traits specific to a unique kind of mind that can become a distinct advantage with appropriate treatment and support. ADHD is not a condemnation of character. Instead, it unveils a kaleidoscope of strengths and a unique constellation of traits deserving of celebration.

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.
