Deep in Kariokor, a slum and a hub of Nairobi’s juakali leather industry, you can’t miss spotting Drogba hard at work at his home made leather press.

Drogba at work

Drogba’s leather press is an assembly of diverse components.

The fly wheels are made up of two used conveyor pulleys full of concrete. These are joined together by two used second hand vehicle half shafts.

The half shafts are connected to an old bench vice screw (hope you are singing along here)

The screw is connected to a press foot

(all together now) “Oh hear the world of the lord” (tune of the kids song Dry Bones)

The print plates are placed on the base of the press frame.

God is able - so is Drogba!

When Drogba spins the fly wheels, he sandwiches the leather between the press plate and press foot producing perfect permanent imprints in the leather

This method is used for most of Kenya’s printed leather products, a huge industry that includes Maasai beaded belts, menu covers, wallets, passport holders, belts, key holders, coasters, handbags, purses, and many fashion accessories and leather souvenir products.

Drogba is 18 years old and works a good 12 hours per day on a casual wage. He has just completed high school and is looking for a college placement.  As you can imagine, he’s a huge fan of his soccer celebrity lookalike and namesake.

Catwalk ready arc welder

This bizarre fabricated arc welding machine is the unique collaboration between jua kali and mitumba. Jua kali literally means hot sun in Kiswahili, and refers to the informal small traders who work outdoors in the sun fabricating mostly work metal and wood items, fixing cars and other household items. Unable to afford new tools they fabricate their own out of locally available materials. Mitumba refers to the second hand western clothing sold on the streets of many African cities. The arc welder uses stolen scrap and second hand wires that are coated for insulation using strips of cloth torn from unsellable mitumba clothes.  This is then wound into the welding machine coils.

God help James if it rains!

I’d gone to Limuru to get a welder for a job on a dairy where I met James Mutahi. He is a typical jua kali wrought iron artisan who operates on the sidewalk outside his street workshop using his own home made tools.  I’ve seen jua kali home made arc welding machines before but usually they are housed in a protective box. To save money James dispensed with the casing revealing the guts of his arc welder.

James was making security grill for a window. There’s a huge demand for arc welding in Limuru especially for gates and window bars which are essential in the high risk security zones of Nairobi and other urban centers.  Nairobi’s security is the result of the collaboration between mitumba and jua kali!

The picture speaks volumes about the Jua-Kali sector in Kenya– cost saving is paramount whilst safety is overlooked hence no housing box – look for welding goggles, fire extinguisher and other safety gear.

I have just spent a week in the field studying Masailand ecology and community conservation with Princeton University students. The location is not that remote (Kitengela and Olerai within 40 km of Nairobi) and the community are wonderfully resourceful when it comes to day to day tools for pastoralism.

Tractor tyre trough for water for goats and sheep

This old tractor or truck tyre was somehow cut, opened up and sealed at either end to make a perfectly good livestock watering trough. Even Joy Adamson noted that the Masai question using modern appliances if home made ones do the job anyway.

Tractor tyre cattle salt lick

Another way to make  a salt lick, Evelyn just cut a truck tyre in half and placed it  on the ground supported by stumps.

home made bucket works perfectly

Why buy a bucket when you can just make one with an old water container and a piece of metal?

Home made shovel

And if you don’t have a shovel for your manure, just straighten out some corrugated iron, cut it and nail to a stick  and Presto – probably more effective than anything you could  buy in Nairobi. Manure is one of the few products sold to passing trucks on these remote ranches.

Keeping land open for wildlife migrations in and out of Nairobi National Park can be costly to those living with wildlife. Those in The Wildilfe Foundations land lease scheme earn 4$ per  acre per year to keep the properties open (no fences)  and to supplement their income they make beautiful beaded artworks for sale on Olerai Conservancy.

It might look like a tough life for some of us, but the Masai out here seem perfectly satisfied and at peace

In Africa bicycle repair men can be found everywhere, from under a tree to in the local vegetable market, one of the best places to find African innovations.

At the Karen market I met the charismatic Mohammed Makokha who proudly showed me two of his home made gadgets that are critical for his business.

I’ve obviously been wasting my money in the bicycle stores.

It’s no secret that Kenya’s rivers are running dry as a result of forest destruction and environmental degradation which has led to a season of blackouts in the capital city Nairobi.

Typical of the ingenious people of Nairobi one street vendor has cashed in on the crisis with this wonderful gadget which he markets as

“Perfect for Nairobi black out”

As you can see I could actually read by the light of this lamp which is made from a used tin can, some pieces of wire to make the connections

And the battery compartment is ingeniously crafted from a circle cut from a retired flip flop.

I love my juakali lamp and everyone that I know  in Nairobi needs one of these lamps. Everything about it is so true to the juakali spirit – hand crafted using colourful recycled tins, and designed for a real purpose with a handle so you can move it around from room to room or hang it up. The vendor tried to sell it to me for Ksh 350 but we settled on Ksh 200 (about $2.50) though I’m sure he would have gone cheaper but the traffic was moving and I had to go.

If you want one visit the Nyayo stadium roundabout.  They stood out amongst the chinese junk that vendors are selling you could practically kit out your house from the junk on sale there. Here’s a short list of what I saw during my 30 minute traffic hold up:

Pens, hats, footballs, blow up spiderman (who needs one of these?), peanuts wrapped in newspaper cones,

smelly car things, driveres licence holding cases, scarves, giant maps, Kenya flags, apples, kits (spiderman kites),

Nike shorts, cowboy hats, socks, oanges, backpacks, cheap watches, key chains knives, olympic medals (yes I wanted one of those!),

knee length shorts for guys who sag, hazard ttriangles, cables to cack your car, name tags for meetings, torches, window wipers (!),

car mats, pears, plumbs, tiny folding chairs for children (or Chinese people?), vehicle number plates, fire extinguishers, stickers,

Enormous framed pictures of furry cats and snow leopards (I can just see one of these this in my house), bananas and bandanas, plastic lunch boxes, pillows and cussions, a huge variety of stuffed toys,

posters with Jesus’ sayings, polo shirts, stearing wheel covers, spanners, screw drivers and of course my favourite – juakali lamps.

Nairobi never fails to impress. I love it. What else have you seen on sale in the Nairobi streets?

I was in Lamu in June and came upon a metal workshop tucked away behind the front row of buildings on the main path from Lamu Town to Shela. Inside were two blacksmiths, Adam Marabu and Abdul Ahmed, working diligently at creating a new anchor. What caught my eye though, was the bellows. They had taken old cement bags and hooked them up to metal pipes in the floor that fed air into the make-shift furnace.

Here’s a short video with some footage of them at work:

One of my favorite stories on AfriGadget was the other unique bellows I found, this time in Nairobi, made out of an old bicycle. Both of these go examples go to show what can be done with very little. It’s about improvising what you have and overcoming a challenge.

Adam and Abdul make all types of items, but they told me that their main products are anchors, which range from small to large (2000-5000/= or $26-65) and, chisels and coconut shellers. They create a lot of the small metal pieces on the local dhows, and also make doors and window frames for the homes in the town. Really, they can make just about anything that you desire, like experienced metal workers anywhere in the world. What’s amazing is what they do it with.

Cement bag bellows and blacksmiths in Lamu Kenya

After all these fascinating AfriGadgets from Maker Faire Africa, here’s another invention as seen by our friend Cedric Kalonji, a Congolese journalist in Kinshasa (D.R.C.):

For the lack of a cheap power supply in the City of Kinshasa, smart mechanics came up with this little stove that speeds up combustion by adding a little electric fan (hidden inside this tube that looks like being part of a flat spring). The fan itself is powered by (Chinese!) batteries and with the burning of charcoal, this quick stove obviously isn’t the greenest solution. But it works and does the job for those who will otherwise have no alternative.

Cedric also mentions on his blog post that it’s difficult to identify the inventor of this device. A perfect example of how low-cost technology easily gets adopted and/or modified (and why intellectual property rights are still a major issue in many places).

Honey is one of the most valuable products of the drylands of Africa. It can be obtained by following a little bird called a honey guide to a bees nest in a tree, whereupon one raids the hive. Or bees can be farmed…in most places a bee keeper simply hollows out logs to make perfectly acceptable hives for local consumption. for commercial purposes however, Langstroth hives are universally thought to be superior to the traditional log hives found in Africa – the box shape make them easy to stack and move around,  and the movable frames guide bees to build combs in an organized manner making comb extraction easy. These hives also have a queen excluder, a mesh grid, usually made of wire or plastic, sized such that worker bees can pass through but the bigger queens cant. This keeps the queen from laying eggs in the honey combs called supers leading to cleaner honey. There are so many NGO’s, GOs and religious Orgs introducing these bright yellow langstroth hives across the Kenyan landscape.They don’t always catch on though – in rural areas people still prefer the logs…

Traditional hive

Traditional log hives are hollowed out logs usually cut from specific tree species with the permission of the local chief. They are hung high in trees and the inside is rubbed with leaves of plants that attract bees – a practice that has been going on for eons. The bees enter the hives through a tiny hole and build their combs willy nilly throughout the space, it’s inefficient and the honey is of a lower quality as the larvae are all mixed up with the honey combs. Not very good for a business approach… or should I say Beesness?.

Langstroth hive in Baringo Kenya

Logic would suggest that the Langstroth hives which produce cleaner honey and they save trees should be favoured right? Wrong! These modern hives are produced by experts in cities and cost a good $100 – far beyond the reach of anyone living in rural Kenya. It’s also rumoured that these hives are easily broken into by honey badgers, over heat in the dry climate of north Kenya driving bees away, and are expensive to maintain. On a personal note, I for one, find them extremely ugly too.

Modified traditional hive

One bee keeping cooperative in Bogoria has figured out a cunning way of modifying traditional log hives to produce more honey. A bee excluder is made using coffee mesh.

Symon demonstrated how beeswax tracks are laid down to guide the bees where to build their combs in neat lines. Cost? One third of the Langstroth hive.

Bucket of raw honey

The honey is collected at night by naked men (yes totally naked …) they say that this prevents one from getting bees stuck in your clothing… I asked about the possibility of getting stung in sensitive places, they said the bees were far too civilized for that…but yes, people had fallen from the trees and been found comatose and butt naked at the tree base…

Honey extractor

Raw honey with comb is sold to the local cooperative where wax is separated from honey. The machine is another jua kali item bought in a workshop in Nairobi.

Home made bee smoker

Bees are smoked out of the hive using a home made smoker.

Production by 40 bee keepers was 8 tons last year, each Kg of raw honey was bought by the cooperative for Ksh 80 ($1), and sold on raw at Ksh 100, or processed and honey sold at Ksh 600 per kg ($8).

8 tons of raw honey were collected in 2008 – this is valued at Ksh640,000 for the 40 bee keepers in the business.

The wax is not wasted but converted into candles which sell for Ksh 10 each ($ 0.12).

Candle making gadget

Using a jua kali gadget for making candles, comprising a string, a piece of conduit pipe and two beer caps….ingenious!

Bees wax candle

Producing the sweetest smelling cheapest candles I’ve ever used. They claim they burn much longer than paraffin candles. Besides they smell delicious

Some sweet facts

· The dry lands of Kenya are the important honey producing districts in Kenya – the semi arid climate, diversity of flowering plants and easy access to fresh water makes it perfect for bees. Kenya is the fourth largest producer of honey in Africa 22,000 tons, China is the worlds largest producer at 299,000 tons (USA produces 70,000 tons) (figures for 2005).

· The group in Baringo produced 8 tons of honey last year.

I love their motto for hard work - "never expect magic from no where".

· Kenya is a world center of bee diversity with over 3,000 species (about 10% of the worlds total number of species)

· Only 150 species or thereabouts produce honey in Kenya.

· Contrary to popular belief, most bee species are harmless… they have no stings

· The Kalenjin people immunize themselves to bees by purposely stinging babies with bees

· In many pats of Africa, honey is an important component of dowry or bride price – a kilogram being made as part payment for the bride – symbolic of the sweetness of sex – or so I’m told

· Bees pollinate most of the crops that we eat

· Bee keeping is most productive in natural habitats, and is a one of the few forms of resource extraction that does not destroy the environment.

The sour facts

· Bees in USA and Europe are disappearing fast – a condition described as colony collapse disorder (ie. Nobody knows why it’s happening). Africa is unaffected so far making honey production a very sweet deal.

Franco Mithika works in Gikomba, an industrial area in greater Nairobi. His job is to take scrap metal tin cans and a soldering iron to fabricate paraffin lamps. Paraffin lamps are used by millions of Kenyans, especially those who cannot afford or get electricity into their home for lighting.

It costs about 110/= Kenyan shillings to make, and it sells for around 150/= ($1.90). You can buy them wholesale for 1550/= ($20) for 24 pieces. It takes about a minute to make one (less for the truly gifted fabricators).

Here is a video of him making one:

Thinking about the unofficial recycling industry

What’s particularly interesting here, is that this scrapes the surface of a rather larger recycling industry that hums beneath the surface of the city. How it works is this. The youngest and poorest go around the city and collect scrap metal of all types. These are then taken to a buyer who sorts them into their different types. This is who people like Franco then buy from and create their wares.

The scrap metal picked up gets sold for just a few shillings per kilo. When sorted, the tin cans that Franco buys, are sold for 300/= ($4) per kilo.

So, there’s a rather efficient system at work. It’s run by entrepreneurs who figure out a way to make things work. A byproduct is that everything (metal) is used, and much less waste than there would be otherwise.
