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.

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

A sufuria is the aluminium pan that is used by virtually everyone in Kenya to make tea, ugali and for cooking vegetables. Like all pots that we use, energy is wasted around the sides of the pot. In Africa this is expensive as fuel be it gas, kerosene or charcoal  is expensive.

This is what it looks like when assembled

This is what it is comprised of – two sufurias to make one efficient one. Basically a hole is cut out of the bigger sufuria – and the piece cut out becomes the lid so nothing is wasted. To wash the sufuria you just dismantle the pieces by just slipping it out. The heat that otherwise escapes around the edge of the pan, is trapped between the cooking pot and  it’s sleeve.

Though it’s not in production, Dominic is using this sufuria at home and swears that it saves at least 50-75% energy on a kerosene stove (his estimate is based on how long it’ takes to boil water).

So if you put a fuel efficient sufuria on a Kinyanjui fuel efficient stove I wonder how much energy saving you could achieve?

Dominic Wanjihia has been previously on Afrigadget showcasing his flat parabolic mirror, container garden, wearable Solar Panel vest, Food dryer, and camel milk cooler.

Its only where Mama herself is there to put more of her good eats on your plate, that I really feel I’m getting a good meal. Why? Because I can see ever step of its preparation, talk with the chief personally, and share the transcending bond of food with my fellow man and woman.

Now I wouldn’t call myself a street food expert – I’m not discerning enough for that title, but I am observant in the different styles of edibles vendors. In West Africa, I’m particularly impressed by the stock street food cooking apparatus. Simple, cheap, and recycled, I present to you the “Rim Stove”.

. .

Using the steel rim off a car wheel as the basic starting point, three metal legs are wielded to the outside of the rim. Inside, a metal grate is added to the bottom to hold in the coals, and some form of pan or kettle stand is wielded to the top.

I’ve seen several variations on this theme, but the basics are always the same – the Rim Stove burns charcoal that’s been ignited in the middle of the rim, fed by air from the bottom and heating a cooking container sitting either on the pot stand or the coals themselves.

During on extending brainstorming session, I even tried to think of improvements to the Rim Stove – how it might burn hotter with less customization. My only solution? Make sure a Rim Stove is cooking chips for your fresh grilled fish.

This is a corn planter. It costs approximately $10 (15 Cedis) to make, and it significantly decreases the time that it would normally take to plant corn. This invention came about by taking a look a medical pill dispensing devices and transferring that knowledge to his communities needs.

Shamsudeen (“Sham”) Napara lives in the norther part of Ghana, which is a lot more rural and isolated than the southern part of the country where you find Accra, or the central part, where you find Kumasi. He has a metal fabrication shop where he builds tools, mostly for agricultural needs of those in the surrounding areas.

He was at Maker Faire Africa this weekend and I was completely amazed at both the ingenuity and the quality of his work.

Shea Nut Roaster

That’s not all that Sham has been up to though, in fact, he’s been busy with a couple other projects. Specifically, he’s been working with Amy Herman from the Univesity of Indiana to figure out how to enhance traditional processes familiar to those in Norther Ghana. This means he does a lot with Shea nuts and the processing of them. It is one of the few fields dominated by the women in the community, and a lucrative business, since the processing from raw to refined can net a good margin of profit.

Below is a shea nut roaster – a small version, since the large ones are the size of a table. It costs around $40 (60 Cedi), and it decreases the time and energy normally expended in the work of getting the nuts ready for processing.

Soap Cutter

Though he has many more inventions in his workshop in Northern Ghana, the last of the three items that he brought to Accra was a soap cutter. It’s a device that has a hinge on one end that opens and closes with piano wires and guitar screws to hold wire tight across the device. As it is closed, it slices the soap cleanly.

He’s been in Accra this last week working in the timber yards in Makola building a food dryer and a food cooler to show at the event. Both of them use air, and the dryer takes advantage of the heat from the sun. More detailed posts will be coming on them, but here’s a few shots of him and the carpenters building the devices.

Mama solar cooker

Made only of cardboard and tin foil this cooker fold up into a neat little package. It apparently cooks potatoes and cabbage in just 1 hour!

She told me that she got it as part of a study – one solar cooker was given to every manyatta. She couldn’t rememer which organization was handing them out but she has adapted hers by putting her pot into a plastic bag which she says retains the heat better. She says she’ll continue using the solar cooker after the study and will even buy one  at Ksh 1,000.

She still has a 3 stone wood fire to cook meat.

I wonder what happens to this device when it rains…does the cardboard become a sodden mess?

During my first week back in Liberia I had been invited to Hawa’s birthday party, on Sembehun Beach, not far for Robertsport, so I passed some time with the ladies while they were preparing western-style food for everyone: rice, beef stake, pasta and potato salad. Then they started stirring what would have to be two cakes for the dessert, and I started wondering how they’d be able to bake them, since the only cooking apparels in the big warehouse were these coal pits on the ground.

They showed me the oven, a big metal cabinet against the far wall; looks like a refrigerator on legs, to allow a coal pit to fit under the bottom, but when I get near it, I see it’s a Blockbuster Quick Drop Booth! The front, where the slit had been closed, faces the wall and the back door is to access the oven; inside are several fridge trays, on which they lay the pans. The door is then locked with a simple bolt and sealed all around with wet cloths.

The cake was fabulous.

[Editor's note: I'm find myself incredibly curious trying to figure out where they found this... How did a Blockbuster drop box get to Liberia?]

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.

It’s not obvious at all for cows to eat this thorny cactus, but Murry Roberts and his wife Elizabeth Meyerhoff told me about an amazing project that their organization, RAE (Rehabilitation of Arid Environments) has been working on. A few years ago they discovered that a local farmer had a bull that not only ate the nasty exotic thorny ugly, plant, but also taught other cows to go for it too.

This is very surprising because any self respecting cow, a sheep or a goat will not touch the nasty prickly pear. The farmer had aptly named his cow Mwalimu (Mwa-lee-moo  means Teacher in Kiswahili) because it taught other cows to eat the prickly pear .

Prickly pear

Prickly pear Tunas for sale in Morocco

Prickly pear (Opuntia ficus indica) is origninally from Mexico and is an economically important species of cactus – the red/purple fruit known as tuna’s are much sought after in many parts of the world. It has been cultivated in many parts of Africa as a hedge, but has become a serious pest because it spreads rapidly degrading ranch lands, and is very difficult to control. As a result, Opuntia eating cows are hugely important in the drylands of Kenya.

How did this farmer get his cow to eat Opuntia? During the drought of 1999 – 2000 grassy fields were reduced to bare earth and cows had nothing left to eat were dying of starvation leading to widespread famine. The story goes that one farmer persuaded his bull to eat the leaves after he had burned off the thorns. Opuntia are 80% water and if one can get past the thorns, the plant is quite nutritious . The other starving cows watched the bull and then followed suit thus saving the herd and the farmer who has never looked back. The thorns are burnt off using wood from another nasty invasive species, Prosopis juliflora – making this an eco-friendly project all round.

As part of RAE’s rehabilitation of Baringo’s drylands, and to make multiply the value of mwalimu bull to other farmers RAE bought the bull and during droughts, Mwalimu goes from one homestead to another teaching herds of cattle how to eat Opuntia, thereby saving hundreds of cattle and people from starvation. For Mwalimu it’s a job that saved his life – he is too valuable to be turned into beef burgers!

The cutting and use of Opuntia and Prosopis is also important in controlling these invasive species which have been planted as live fences, but which are fast becoming weeds in the degraded Baringo lowlands. Apart from prickly pear eating cows RAE also restore grasslands and eliminate soil erosion in an innovative project that has huge application across the drylands of Africa. We met women who were doubling their money by buying and fattening cows on restored grasslands in a 3 month period!
