Data science interns tackle Cape Town water crisis

Cape Town’s Day Zero for running out of water may have been postponed for 2018, but for interns at the Explore Data Science Academy (EDSA) in the city, their project was an opportunity to take existing data and derive fresh insights into the City’s water crisis.  

The question posed to the students was: “What are the supply and demand factors affecting the Cape Town water crisis?

Using publicly available data, they showed that the blame cannot be attributed to any single cause, but that multiple factors in varying degrees each contributed to the water crunch.

The students concluded that a combination of low rainfall, population growth, shifting consumption levels as well as evaporation, were all factors affecting the City’s critical dam levels.

The project was the first to be set by the Academy, and was handed to the first intake of 100 students on their first day at the Academy in January this year. They were given two months to work on the problem, with the EDSA supporting them with the necessary skills to tackle the problem.

“In essence, data science is about taking real world problems and finding real world solutions,” said Aidan Helmbold, co-founder of the EDSA.

“The water project required our interns to make use of various available data sets and technology to analyse the City’s water consumption, and to make these insights available so that the City could better understand the underlying dynamics,” Helmbold added.

Students had to analyse the main supply and demand factors affecting the water crisis.  Demand side factors were drawn from water consumption data available on the City of Cape Town’s Open Data portal.

On the supply side, factors such as dam levels, and the impact of weather data, such as rainfall, temperature and windfall patterns on water evaporation, were considered.

Analysis of water demand also took into consideration population figures from the 2011 census, the impact of water leaks as well as usage from sources other than households, such as industries and farms.

“I think the most astounding aspect for us as education providers was to see how much 100 young minds can achieve with only three months of data science training behind them,” Helmbold said.

“We were also amazed at how quickly the students were able to adapt to the softer skills, such as teamwork and the realities of managing multiple project deliverables.”

“Many of these young people come from very humble circumstances and have only a matric to their name. Yet they have demonstrated through the project, their ability to get to grips with complex problems and to come up with life-ready solutions to them. ”

The EDSA will present the data finds to City of Cape Town officials early in June.

“Ideally, the EDSA would like to partner with the city to contribute to deepening the understanding of the role of data and the value its insights can bring to the decision making process,” Helmbold said.

CoCT and CiTi’s #newnormal – Cape Town Water Saving Design Sprint

In a separate but related endeavour, the Cape Innovation and Technology Initiative (CiTI) together with the City of Cape Town, recently held a weekend-long hackathon to come up with solutions that would engage and encourage Capetonians to continue to save water and remain conscious of their water habits.

In order to address this challenge, a two-day design sprint was held at the Woodstock Bandwidth Barn. Participants were given the challenge to ‘Design a digital campaign, tool, game or app which will help make water-saving the new normal’.

Drawing on the City’s Open Data portal, this event challenged teams to come up with ideas on how to use technology to motivate long-term behavioural change regarding water saving and to propose solutions that were relevant to the wider community.  Participants were also briefed by Green Cape and behavioural design professionals.

The aim of the user-centred design hackathon was to bring together people from diverse backgrounds, experiences and skill sets.  About 60 members of the public including 30 of the EDSA’s interns were involved in the design sprint.

The weekend-long event was facilitated by experienced design thinking professionals who took teams through a structured process.

“This allowed people to participate in the event without already having a solution in mind, focusing rather on getting teams to understand the problem from a user perspective first,” said Michelle Matthews, Head of Innovation at CiTi.

This user-centred approach included having participants’ interview members of the public, to help participants propose solutions, which citizens might actually need and adopt.

One of the EDSA teams came up with an idea for a Sims-like game that tracked an individual’s water consumption rates, rewarding them with points for saving water and connecting them with others with similar household set-ups to benchmark usage and share tips.  This team eventually came third in the event.

“We were delighted by the calibre of solutions that the teams demonstrated, which had the potential to be applied to one of the biggest issues facing the city,” Matthews said.

Mobile is the new branch

Standard Bank has launched an account for mobile devices that gives back 500MB of data a month

Standard Bank has introducd a R4.95p/m bank account called MyMo that customers can open on their mobile devices, loaded with data and airtime offerings and other benefits such as virtual and Gold physical card.

MyMo account holders will also enjoy the convenience of a cheque account through a Visa and Mastercard gold card. Once the account is open, users can choose to either receive R50 in airtime or 500MB of data a month, if their card is swiped more than four times a month. A further megabyte of data is loaded on the account for every R20 spent.

“MyMo is an account for everyone, whether you just landed your first job or have been around the block. With no documentation required it only takes a few minutes to open the account,” says Funeka Montjane, Chief Executive for Personal and Business Banking, South Africa, at Standard Bank Group. “For just R4.95 a month customer will be able to enjoy free swipes and ATM withdrawals at only R6.50 for amounts under R 1 000.

“Mobile is the new branch. This account is about bringing the mobile branch into customers hands, it is about convenience and security while banking.”

She says mobile offers low cost transactional banking which integrates people and businesses into the new connected economy, making mobile the new branch ecosystem that will drive and connect Africa’s growth. Physical connections to the economy are rapidly changing to digital where banks have to move from being financial institutions to service organisations.

“In the past people congregated in communities and eventually cities to maximise the advantages of connectivity. Today a simple hand-held device has the potential to open infinite doors, transforming individuals’ access to opportunities, regardless of where they are, and like never before in history. 

“Historically, a bank account represented access to economic citizenship. Today, having a simple device enabling digital access to a modern banking platform is a passport to global connectivity and vast human development potential.”

The bank says it is using technology, and mobile phones in particular, to deliver low-cost transactional channels accessible to all our customers. The evolution in mobile can be seen in transaction options like cash back at the retail checkout till rather than the ATM, free digital banking rather than using a branch, and the ability to transact using digital wallets, even without a bank account.

“Developing comprehensive connected ecosystems requires a mind-set change from Africa’s banks,” says Montjane. “Banks will evolve away from traditional financial service organisations, into service ecosystems enabling broad universal access to almost everything like enhanced purchasing experiences of vehicles and homes, online procurement of goods and services and lifestyle elements like rewards and travel. 

“These connectivity drivers will also act to future-proof evolving connectivity ecosystem by allowing us to offer untold future services while deriving income from as yet unrealised revenue streams,.   

From a customer perspective, the kind of ecosystems of knowledge, access and, ultimately, connectivity that banks will come to provide will radically transform the share of life that almost all individuals will be able to access.”

Two-thirds of SA staff hide social media from bosses

With 90% of people in employment going online several times a day, it can be hard for most workers to keep their private and work-life separate during the working day (and beyond). The recently published Global Privacy Report from Kaspersky Lab reveals that 64% of South African consumers choose to hide social media activity from their boss. This secretive stance at work also extends to their colleagues, with 60% of South Africans also preferring not to reveal online activities to their co-workers.

Globally, the average employee spends an astonishing 13 years and two months at work during their lifetime. Interestingly though, not all this time is directly related to solving work tasks or earning a promotion: almost two thirds (64%) of consumers admit visiting non-work-related websites every day from their desk.

Not surprisingly, 35% of South African employees are against their employer knowing which websites they visit. However, more interestingly, 60% of South African are even against their colleagues knowing about their online activities. This probably means that colleagues constitute an even greater threat to future perspectives of an office slouch or maybe the relationships with colleagues are more informal and therefore, more valuable.

On the contrary, social media activity appears to be a less private domain for many and therefore, more suitable for sharing with colleagues but not the boss. This is probably because workers fear harming the public image of a company or interest in decreased staff productivity motivates companies to monitor employees’ social networks and make career changing decisions based on that. Such policies have led to 64% of South Africans saying that they don’t want to reveal their social media activities to their boss and 53% even don’t want to disclose this information to their colleagues.

A further 29% are against showing the content of their messages and emails to their employer. In addition, 3% even said that their career was irrevocably damaged as a consequence of their personal information being leaked. Thus, people are worried about how to build a favourable internal reputation and how not to destroy existing workplace relationships.

“As going online is an integral part of our life nowadays, lines continue to blur between our digital existence at work and at home. And that’s neither good nor bad. That’s how we live in the digital age. Just keep remembering that as an employee you need to be increasingly cautious of what exactly you post on social media feeds or what websites you prefer using at work. One misconceived action on the internet could have an irrevocable long-term impact on even the most ambitious worker’s ability to climb the career ladder of their choice in the future,” comments Marina Titova, Head of Consumer Product Marketing at Kaspersky Lab.

To ensure workers don’t fall prey of the internet threats at a work, there are some core guidelines to adhere to in the digital age:

  • Don’t post anything that could be considered defamatory, obscene, proprietary or libellous. If in doubt, don’t post.
  • Be aware that system administrators may at least, in theory, be informed about your web browsing patterns.
  • Don’t harass, threaten, discriminate or disparage against any colleague, partner, competitor or customer. Neither on social networks or in messages, emails, nor by any other means.
  • Don’t post photographs of other employees, customers, vendors, suppliers or company products without prior written permission.
  • Start using Kaspersky Password Manager to ensure your social media and other personal accounts are not at risk of unauthorised access by someone else in an office. Install a reliable security solution such as Kaspersky Security Cloud to protect your personal devices.
