Resource Allocation and Sustainability

One of my favorite parts of work in Zambia are the trips to the field, installing or fixing hardware in rural clinics. We install a low power computer system for data entry, and train people how to use touchscreen computers that utilize the cell network to transmit data. Half of the sites that we work in are off the grid, and require a solar power installation. We also give community workers cell phones and a custom application, so that data can be passed between them and the clinic. Working with my hands, seeing tangible benefits from a days work, and the 'thank you's' make the job rewarding.

I've just come from one of the remotest of the sites in which we are working. There is no cell coverage. There is a small hill a half an hours walk away where you can get half a bar of service, sometimes, on some phones - but that isn't going to help our data connection at the clinic. Using the cell network to transfer information thus far has been relatively easy and affordable. However, this option wasn't available this time. After surveying a number of options, the time vs money vs schedule dilemma forced us down the path of satellite internet. This wasn't just the shotgun approach, but the golden-plated shotgun approach. Furthermore, the community health workers, without good cell coverage they can access, are given phones with a wifi connection which they can bring to the clinic and connect through the satellite internet to send data.

Think about this for a moment. Rural Africa. Mud huts with thatched roofs sparsely populate the only access to the clinic, a bumpy dirt road. Naked children running around barefoot. Water comes from a river a 45 minute walk away. No electricity. Most people here don't have a cell phone because the service is so poor. The Zambian team I'm working with jokes that the people here aren't even Zambian - they don't know who any of the last four presidents have been. If government services never reach a remote location, that location isn't given any say in the government, and not much has changed since 1) independence 50 years ago and 2) since the country was arbitrarily drawn by colonists a few centuries back, I don't know if I would consider myself a Zambian in that situation either.

But I digress.

Go back to the picture painted of rural Africa. Now add solar panels and a computer. Not too bad. We installed a few light bulbs as well. Now, add a satellite dish and a wifi hotspot. Is this sustainable? Is this the right use of resources? I went home after beginning the installation feeling that no, this wasn't quite right. Yes, the data arm of the project is a main support for the medical intervention that is aiming to drastically reduce mortality rates. A slightly inebriated local regaled me during a work break:

'We need help. we need water, cell coverage, medicine. Can you help?'
'I am trying to help'
'No, we need help. Can't you just send in an application?'
'Um, to who?'
'Just send in an application. We need help.'
Ah yes, just send an application to Bank Mzungu, and all your problems will be solved.

Most of the clinics I have been to have had solar power installations before. None of them work anymore. A cousin decided to plug in his TV and DVD player. Lightening struck the inverter. They ran out of light bulbs. They plugged DC items into AC circuits or vice versa, stole the batteries, abused the inverter, or threw rocks at the solar panels (haven't seen this one personally, but have heard LOTS of stories).

Upon returning to the clinic the next day to finish up, the in-charge was back to complain that we were only installing a few lights, and not lighting the entire clinic or providing electrical outlets. I tried to explain that the system we were installing was minimized for price and functionality. The wiring for lights and sockets had already been installed and at one time they worked - this was the DVD abuse case. After the inverter broke, the battery was stolen, and the system fell into disrepair. When taken to a dingy, dirty store room, there was a 6kVa UPS still in plastic, donated by an NGO. This is used to take AC input, clean it up and store it in a battery, and plug fancy electrical equipment into it, which can be powered for some time after the AC input dies. This was the biggest one I had ever seen, by far. There is no AC input and no fancy electrical equipment. This single piece of equipment is probably worth tens of thousands of dollars - and is sitting, unused, unable to be used, in its wrapping in a corner of the Zambian bush. The jungle will overtake it sooner or later. Then she showed me a large generator, also sitting in a room. She also mentioned that she had eight solar panels sitting at her house if we wanted to wire them for her. Ah yes, and when a woman came into the clinic in anaphylactic shock from a scorpion bite, they didn't have the proper medicine to treat her.

I wired the clinic to run off of the generator, taking the burden, and hopefully the temptation, off of our solar equipment. I was satisfied to see visible progress. The lights and the sockets will now all work - as long as the generator can be maintained and fuel provided (not too much of a hassle, actually). We parted ways, and as we left the clinic, I spied the egregious satellite dish. All I could do was sigh, and shake my head. On to the next clinic.
