Bringing science to the people: The African story and the legacy of South Africa

The week ending 8th december, 2012, saw me attend a one week 'Adaptive Optics and Atmospheric Characterization summer school' in the town of Sutherland, South Africa. Adaptive Optics refers to a class of latest technological devises designed to eliminate degradation of star images generated when turbulent motions of air molecules in the Earth's atmosphere interfere with light coming from a star. The in-depth study and scientific modelling of the entire atmospheric layer is what is called atmospheric characterization. The main aim of the school was to bring together some of the world leading experts in adaptive optics technology, software development and atmospheric characterization, and, students from African countries and abroad, to share knowledge on the modern techniques required when choosing a site to locate an optical telescope. However, apart from enjoying the highly illuminating and mind-blowing lecturers delivered by the invited lecturers led by the outstanding South African Large Telescope (SALT) project scientist at the South African Astronomical Observatory (SAAO), Dr David Buckley, I also-as I often usually do- found some time to interact and learn from people in the local community. But, although during my helter-skelter walks, I was touched by the obvious signs of visible poverty and idleness amongst the people in this semi-desert Springbok invested area, where the main economic activity is sheep farming, two things stood out above the rest: (1) the impeccable Afrikaans language-accented english and the genuine hospitality of the people, and, (2) the impact of the SALT telescope on the local community's socio-economic status. SALT is the largest single optical telescope in the Southern Hemisphere and among the largest in the world, commissioned in 2005, and owned by South Africa (1/3) and 12 international partners. To crown it all, an outstanding public educational facility called “the Sutherland Community Development Center (SCDC)” founded under the innovative and visionary leadership of the International Office of Astronomy for Development (OAD)'s current director Kevin Govender, caught my ingenious attention. It is the positive change that this facility with a single sitting capacity of over 100 people and close to 30 modern computers connected to fast internet optical fibre, complete with a baby's toy corner, that motivated me to pen down this article. It's my sincere hope that by reading this article you will be as motivated as me, so that together we can work towards implementing a similar concept for the rural people in our home countries. Together we can transform Africa from a 'basket case' to 'the bread basket'!


Despite mild efforts to improve literacy levels across different countries in Africa, the road leading to the promised land of Canaan where the honey of “100% literacy” flows freely, still remains largely illusive. Access to good education, especially in rural areas and poor townships, remains a challenge, prompting many youth to engage in illegal and criminal activities such as prostitution, thuggery, mugging, drug and substance cartels among others, in order to put bread on their table.

The aging and the old are not left out. They are often frail, sick or both, with their sad grinned faces mirroring a written history of many years of suffering and hard life. Many will often be seen swallowing bitter saliva in anticipation of a better tomorrow. Their hope is that their sons and daughters would one day find decent jobs, that their half-naked, impoverished grandchildren would get a good education and have a better future than theirs. But how many of us of the privileged clout care? Has our leadership failed? Can anyone provide leadership out there?

Your answer to the above questions is as good as mine, but one thing is clear: that many of us have failed! I will tell you why. We have failed to think of how far we have come (for those of us who've surmounted difficulties to succeed-me included) or how privileged we are (for those who've never lacked or struggled in life). We have failed to remember who paid for our college education. Did I hear someone say a government/university bursary? Company bursary? Or my parents money? But where do governments, universities, companies or your parents monies come from? Doesn't it come from taxes levied on all cadres of people directly or indirectly? Doesn't it come from investments, mineral exploration and farming on the land that once belonged to the ancestors of the same poor and disadvantaged people? Aren't we then supposed to plough back to society that which it has given to us?

My late grandfather, a visionary, hardworking and typical African-styled man-may God rest his soul- always reminded me one thing. You see, during the time when I grew up (proudly close to 3 decades ago), in my rural home Kisii Kenya, it was a common phenomenon to pump into mushrooms in the forest while grazing my father's cows or while harvesting guavas in the bushes or during our “wild bees and termite-harvesting” errands. He always reminded me to cut the tip of the mushroom and return it to the hole from which I uprooted the mushroom. Why? He said that by doing so I could return the following day and harvest more mushrooms! And surely I often did-unless someone picked the mushrooms earlier than me- I thought.

But how many of us are willing to return the 'tip' of our mushroom to the 'hole' from which we uprooted the mushroom? We all seem to have locked our hopes in the safes of selfish political mandarins-the often pot bellied elites a majority of whom are merchants of impunity and the epitome of chagrinism- and thrown the keys to “hell”. Whatever that means. But what I'm I talking about? Or can we do better?

Well, my answer is YES. It has been done, it's being done and it can be done, the only question is how. This brings me to the main theme of this article; the story about the Sutherland Community Development Center (SCDC).

The inception:
Mr Kevin Govender, the brain behind the center's concept is a man who needs little introduction. His undying love for astronomy education, and the desire to foster interest in maths and science saw him propel the SALT Collateral Benefits Program-a program that was designed to tap into the investment in the SALT telescope for for the benefit of society- to greater heights. His legacy, while at the helm of leadership of the SALT Collateral Benefits Programme, played a key role in steering South Africa to winning the bid to host the International Astronomical Union's (IAU), International Office of Astronomy for Development (OAD), which he currently heads. It is after the establishment of this office, that astronomy has continued to blossom in Africa, and nothing best illustrates this fact other than the recent landmark victory that saw Africa win another bid to host three-quarters of what will be the world's largest radio telescope ever built; the Square Kilometer Array (SKA). More bids are on the way, and africa will win them. The impact of the SCDC project on the local community is one such a 'smaller' bid-and I know there may be other small ones elsewhere in africa- worthy mentioning.

The Objectives:
The SCDC was designed to be a place for the community to grow, to develop and gain life skills, before venturing to the outside world. It's aim was to provide free fast internet to the local community and offer a play and learning facility to small children, the youth and young parents for purposes of their self empowerment.

The Internet Connection:
Internet to the center is provided by two wireless radio links; one installed on a tower on top of the hill facing Sutherland and the other on top of the Community centre building. The former consists of a high-powered 5GHz antennae through which a signal from the SAAO's Sutherland plateau data center is sent and re-routed via the second radio link before being routed via a normal ethernet cable inside the center, and then to all computers. The wireless kits are all solar powered with batteries and continually monitored from the SAAO IT Center in Capetown, in order to send someone with a generator to boost the power supply, incase the battery power levels drop too low. This ensures that the centre is always connected and online.

The Benefits:
Apart from providing the local community with fast internet, providing online research opportunities and a quiet study environment for the youth and learners in the area, the centre also offers free mentorship, guidance and learning assistance to the learners. And according to the Sutherland SALT Collateral Benefits Program director, Mr Anthony Mietas, the number of visitors to the center remains high and it's services are already impacting positively on the lives of the community. The SAAO IT Center's director Hamish Whittal, further points out that phase two of the project will see the only two schools in the area; Roggeveld Intermediary School and Sutherland High School also receive internet connection.

The future of the youth in Sutherland therefore looks bright, or so I can say, and a similar model is worthy adopting across African countries in the quest of making Africa a technology and educational hub!

The Parting Shot:
One unique pillar underpinning success of the SCDC is the power of the volunteers. Indeed, the mentoring and guidance carried out at the centre is done by self-motivated and passionate volunteers who are 'ploughing' back to the society that which it has given to them. But, that is one way and there are many other ways-to skin the CAT. This then reinforces the slogan “It has been done, it's being done and it can be done.”
