High Technology and Appropriate Technology

Nakuru is not far from the equator and today we travelled to Mogotio, even closer to the equator. We were there to irrigate onions, peppers and other vegetables. The irrigation process for a small shamba (smallholding) is fiddly and time consuming. The field is beside a river. The pump is petrol operated. But the process of attaching bits of pipe so that the water reaches the farthest parts of the shamba takes several people and a lot of time.

In fact, it's a process of attaching, detaching and re-attaching bits of pipe until the whole job is done. While two people add and remove pipes, two others use hoes to make furrows for the water to flow through and block furrows where adequate water has entered. Why do people not use good lengths of flexible pipe or drip irrigation?

This is a one acre shamba, the kind and size that many Kenyans own. It's for growing small amounts of produce. It's labour intensive but labour is cheap, flexible pipe and other pieces of equipment are expensive. If the shamba was bigger and more productive, we could afford drip irrigation or some other form of irrigation, but this sort of technology is beyond the means of most people here.

So I was pretty annoyed to come across an article about some 'clever' people who have developed a device which allows a farmer to SMS or call a number to turn on their irrigation system. Great, but people who can afford an irrigation system that can be switched on and off don't have to do much work on the shamba themselves. They employ people to do it. It's not the first time I have seen articles about how brilliant mobile phones are. They have their uses but most of the problems poor people suffer don't go away just because they have a mobile phone.

I also came across an article about how Uganda is using mobile phones to spread the 'message' about HIV. Do they really think their unsuccessful and very expensive programmes over the last 20 years failed because of the medium that was used? How much evidence do they need that the problem was not just with the medium?. Many people there and in other countries know all sorts of things about HIV, not all of them true. But they still engage in the sort of behaviour that is thought to spread HIV. So why should spreading the 'message' by mobile phone change anything?

Anyhow, as well as hoeing and irrigating the shamba, we were in Mogotio to demonstrate the process of solar cooking to some people there. We cooked rice, ugali (boiled maize meal) and sukuma wiki (a popular collard green). Sounds a bit starchy but Kenyans like a fair bit of starch. The result was excellent. The area is so hot that things cooked quickly. So the workers in the field were impressed at the large amount of food they were provided with and even more impressed that no charcoal or wood had been used in the cooking process.

I had my worries about the ugali. It is almost worshiped here and getting it wrong could be fatal. But it turned out pretty solid and sticky. I have tried a few other things, stew, various vegetables, even soda bread. They are very good, as long as the sun lasts. So it's time to be more adventurous and do a bit of experimenting. I have no doubt that some 'genius' will be able to invent a device that pulls a screen across the solar cooker when the food is cooked. Until then, I'll just use the time honoured process of looking at the food.

How Many Mobile Phones Does it Take to Change a Bandage?

The media never tire of writing self-satisfied articles about how brilliant technology is and how so many things can be done now because of technological advances. No doubt, there have been remarkable advances and we can now do things that were never dreamed of a few decades or even a few years ago.

Despite this, there is an increasing number of poor and undernourished people. Most, if not all the Millennium Development Goals are going to be missed by most developing countries. People are dying of preventable and curable diseases. Yes, preventable and curable. They can be prevented and they can be cured but, for some reason, they are neither prevented nor cured.

There is a whole rash of articles on the use of mobile phones for HIV care and prevention, articles written with all the confidence you would expect of suit-wearing, job-holding academics and consultants. But all these articles appear to be based on anecdote rather than on comprehensive data. You can support adherence, send prevention and health messages, even diagnose diseases and perhaps issue prescriptions.

But that's only if there is some kind of infrastructure available. There's little point in issuing a prescription to people who can't afford the medicine or the trip to the pharmacy or where the pharmacy has run out of supplies or if there's no public transport or if there is no clean water to take pills or...etc, etc. Even where the infrastructure is in place, Kenya is not blessed with adequate numbers of trained health personnel.

I'm not running down technology, I agree mobile phones are great, as are handheld computers, laptops, mobile internet and anything else that can be dreamed up. But ultimately, people also need the basic things that the survival of the human race up till now has depended on.

That's what's missing, food, water, sanitation, basic health, basic education. Missing are the education, health and social service facilities and, more importantly, the trained, skilled and well equipped people who provide services.

All of the health care workers I've met recently have mobile phones. Notably, they are also all volunteers, with very little training. There are not too many people they can call, least of all skilled medical personnel, as they are in very short supply. And if someone calls them late at night, most of them don't even have a bicycle to get to the client. If the client needs to be moved, they might have a wheelbarrow or a cart to get the client to the nearest public transport vehicle. This is not a joke.

There is also a shortage of electricity here and a shortage of money for credit. Many handsets don't work or don't work very well because of the heat and dust or because they are cheap handsets that don't function for very long. True, people can use solar energy to charge their phones but most don't because this particular technology is too expensive.

Mobile services could even be paid for by the state. But the state doesn't provide the few pennies necessary to treat and prevent intestinal parasites that stunt the physical growth and mental development of vast numbers of children every year.

I'm sure people are very happy that we 'can' do all these marvelous things with technology but they'll be a whole lot happier if their immediate needs are attended to, whether they require technology or not.
