Congratulations to all the individuals and organisations involved in organising the successful World Bee Day celebrations in Nairobi on May 20th 2019. The 1st World Bee Day in Kenya (2018) was celebrated in West Pokot County in Kapenguria town. The 2nd World Bee Day 20th May 2019 was held in Nairobi County at Railways Club grounds.
World bee day celebrations were organised by the Apiculture Platform of Kenya (APK) in collaboration with the National Government, FAO, Nairobi City and County Government. A whole range of beekeeping stakeholders were involved in organising the event (including ABRC). There were 32 exhibitors on the day including 2 exhibitors from Uganda. The celebrations included a walk through the streets of Nairobi to raise awareness of bees among the ordinary public and educative talks, in addition to the exhibit stands. Well done to all involved for raising awareness on the value of bees and beekeeping.
There are places where the Langstroth-type hive is suited to local conditions – where bees are fairly docile, where farmers can afford this type of hive (plus the extractors and other equipment needed to harvest the honey) and where yields of honey justify investment and management; but unless a few basics are recognised, beekeepers (and the organisations that support them) can get themselves into a bit of a gummy mess.
Beekeeping in Rwanda is a bit of a mixed bag. I met some excellent beekeepers in the country, especially in Nyaruguru district, near to Butare, in the south. Many cooperatives use a mix of traditional, top bar and Langstroth hives; and they manage their apiaries, and their hives and their bees. They keep everything clean and tidy, specialise in beekeeping and have made it their main occupation.
They are lucky. Like most parts of Rwanda, their bees are nice and gentle, there are commercial companies working with them (providing hives and bee-suits and support), and the local countryside can provide good yields of high-quality honey.
But not everyone in Rwanda is doing so well. Look at the photos. They were all taken in another district, in Rusizi. Picture 1 shows a yellow brood box on top of a blue brood box on a blue floor. This photo demonstrates one of the biggest practical problems for beekeepers using Langstroth-type hives in Africa. It illustrates a series of problems. The blue floor is too big for the blue brood box, so the brood box cannot fit properly on the floor. Therefore, the hive slopes, the entrance is narrower on one side, and there are gaps along the back. The yellow brood box on top is yet another size – it’s narrower than the blue one. Although it just-about fits on the blue box, look along the front. The yellow box is shorter so there’s a gap. Can you see where the bees are going in and out?
There are so many gaps in this beehive that I wonder how the bees manage to look after their brood-nest and honey. Imagine what happens in a rain storm. The rain will go straight into the blue brood box along the gap left by the yellow one, especially if the wind is blowing it sideways. And the rain will fall onto the floor, then run inside the hive.
Because the two brood boxes are different sizes, the frames cannot be taken from one part of the hive to the other. The frames in the blue box are too big to fit the yellow one. This is a common problem, and it means that frames from different hives cannot be easily swapped around. (Beekeepers swap frames from one hive to another quite often, sometimes when cleaning them and at other times when managing the bees.)
Now look at Pictures 2 and 3. The two brood boxes are the same size, but there are lots of gaps between the top one and the bottom one. The gaps are evenly spaced. Although the two brood boxes are the same, the frames must have been taken from a different sized box. They are too big. The result – the bottom of the top brood box is not resting on the top of the bottom box. In fact, it’s resting on the frames in the bottom brood box as these frames stick out over the edge. Because the frames are too big, the hive cannot fit together properly.
What is the problem with that? Is it just that the trainer is fussy about the hive looking nice?A Langstroth-type hive has lots of parts that need to fit together properly. More parts; more to go wrong! Holes and gaps allow bees to go in and out wherever they want; but the bees don’t LIKE to have lots of holes because other things can go in and out of the beehive as well – ants, mice, wax moths, robber bees, wasps and hornets; and the wind, dust and rain. Bees fill up the gaps to make their homes secure. They fill the gaps with propolis, which is like an insect glue. Sometimes propolis is crisp and hard, and at other times it’s gummy. Both types make a mess, and make it difficult for the beekeeper to open and close a hive. Look at the propolis in Picture 4 – the black stuff. There is loads of it.
Look at Picture 5 and work out what is wrong with this hive. The floor is too big, the yellow brood box is bigger than both the blue brood box and the roof (which doesn’t fit properly either).
Propolis doesn’t just make a sticky mess; it also reduces the honey crop. Bees use a lot of time, resources and energy to collect and process the materials that make propolis. When they are making propolis they are not making honey. If bees didn’t have to fill the holes created by clumsy beekeeping, they could spend more time foraging and making honey.
So, how do we solve this problem? There are some things that projects can do, and a few more things that beekeepers can do. Projects can
think about whether the complicated Langstroth-type hives are the right ones for the communities they are working with
try to help standardise the specifications of the Langstroth-type hives used in each area
provide groups and cooperatives with standardised Langstroth-type hives so the all the frames, brood boxes, floors, cover boards and roofs are interchangeable
provide training to beekeepers to manage the Langstroth-type hives effectively.
And beekeepers need to
make sure that different hive components are sorted out, so the right parts can be put together
clean hives regularly, removing all the propolis so that the frames and brood boxes fit together properly
make sure that any new Langstroth-type hives are the same specifications as the ones they already have (whether they are being bought by the beekeeper, or provided by a project).
I spent a lot of time in Rwanda trying to decide what sort of hives should be encouraged. Most beekeepers have traditional hives; some cooperatives have a mix of traditional, top bar and Langstroth-type hives; and the Ministry, NGOs and companies tend to favour the Langstroths.
But I think the final decision should be with the beekeepers. The Langstroth-type can work in Rwanda. The bees are fairly docile, so they can be managed quite easily; some farmers can buy or obtain this type of hive (plus the and other equipment needed to harvest the honey); and in many parts of the country the yields of honey do justify investment and management. Furthermore, there are some beekeepers (like those I met in the cooperatives in Nyaruguru district in the south) who do have the commitment and management skills to take advantage of the possibilities provided by the design of the Langstroth-type hive, on order to manage bees and maximise honey yields. None of the Nyaruguru beekeepers’ hives were a gummy mess of propolis.
Unless all these factors are in place (docile bees, good forage and good management skills) people working with beekeepers are irresponsible if they only promote expensive complicated Langstroth-type hives to people not adequately equipped, skilled and committed enough to use them.
Make sure that beekeepers can (and do) manage their beehives so their bees produce what they want. The management of beehives must make sure the bees are industrious, and processing lots of honey instead of steadily blocking up gaps and turning their beehives into propolis factories.
