Kayima Dam - Location, Weather and Ecology
|
Part of the Kayima dam watershed (click on image for full size view) |
Kayima is about 40km from Yengema airfield and 40 km from Mount Bintumani in the "Loma Mountains No Hunting Forest Reserve", which you can see in the background (above photo). The Kayima dam is situated near the top of a hill somewhere in a shallow valley between two summits, the ground rises on both sides, with the crest on the left (facing upstream) higher than the right. Rainfall no doubt drains from the forested areas on both crests, but the stream supplying it must be fed from a greater distance or from other water sources within the watershed, as it continues to flow throughout the dry season after months of zero rainfall. The surrounding area is forested with minimal farming activity, however there are numerous large patches of deforested areas nearby and in the wider region.
An in depth study into how deforestation and land use has affected local watersheds, micro-climates, soil health and disease vectors would make a valuable contribution to conservation, water, soil and food security, wildlife habitats and public health for the area and would contribute to local knowledge, sustainable practices and livelihoods. This would also make a great science, conservation and sustainable land management project for local schools and farmers cooperatives. It would also be interesting to find out how the nearby Loma mountains affect local climate and watersheds.

Farmers have reported changes in the patterns of precipitation in recent years. Kayima had a reputation for having no mosquitoes, completely incongruent with the norm in other parts of Kono, however during recent years and in the 3 months I was there between Jan-Apr, I noticed a significant increase from historical numbers of mosquitoes and plenty of cases of malaria. Kayima has a reputation for being very much cooler than nearby Koidu only 55km away. On some mornings I had to wear a fleece, and locals wore coats, temperatures can reach lows of 10-15 degrees C and it can feel colder to those acclimatised to tropical weather. As the dry season progressed, day and night temperatures became significantly higher and the flow and quality of water in the large stream through the town, Kaiso, drastically reduced. The characteristic reddish-yellow tint of river and stream water caused by coloured dissolved matter became much deeper in Kaiso during March and early April. Farmers reported that they expected several light pre-rains in March, not enough to saturate the ground and quickly burned off, followed by a dry period during which they expected to finish preparing their farms for the planting season, with the first rains of the rainy season starting around mid April. Their predictions were accurate in Kayima and the surrounding chiefdom, however in Koidu I observed a couple of quite heavy bouts of rain during the same period. Questions and theories were discussed during that time regarding this uneven weather pattern.

Kayima Dam Project Planning, Negotiations, Town Mobilisation
2nd to 5th February 2014
Back in town, we discussed what expenses there may be. This was to be a voluntary community initiative so no budget was set for labour. We did feel to be on the safe side we should offer to cook a picnic for the volunteers at the end of the second day as an added incentive. However, we needed buckets for bailing, shovels, cement, sand, gravel and the use of the local cooperatives' 'walking tractors' to carry them. A major task was to clear the road to enable vehicles to travel between the secondary school and the Turntable. Another advance task was to clean the alternative unused water source at the far end of the town not far from the primary health care clinic, a stream feeding a small cement-covered shallow well. This would provide emergency water for the days the reservoir would be out of commission. For washing and laundering, many used Kaiso, a stream at the entrance to the town.
Before the dam was dredged and we could examine it we didn't know the extent of the damage or the quantity of materials we would need, we decided to work on the assumption that based on the limited extent of the leak, damage would not be too extensive and would not require large amounts of materials. We undertook to do what was within our means. At the bare minimum dredging and excavating the area cleared a decade before by the town and the International Rescue Committee, with the possibility of introducing fencing to deter local wildlife, would ensure a larger water storage area for the town making supply more resilient, and would hopefully result in relatively cleaner water.
As an added incentive to encourage the towns cooperation I offered to contribute 10 bags of cement which Bondu Argue agreed to match as needed. We instructed key people to pass the message of the offer along and suggested it was time limited and contingent on the town coming together urgently to volunteer.
For the next few days we talked with the town chief, section chief, the locally based regent paramount chief, and local youth leaders who had meetings to discuss the dire water situation, its health risks to the town and what should be done about it. I visited and spoke to Mohamed Kamara who was visiting from Saudi Arabia where he lives, and building two mosques in Kayima and Wordu. He offered to match the contributions made by Bondu and I.
I spoke to Abu Jawara the Paramount Chief's aide de camp in Kayima and by phone to Paramount Chief Sheku Fasuluku, my younger uncle, who was in Freetown to see what he would do to assist the proposed project. From past experience he was sceptical the town would agree and mobilise, however he gave his support for the venture.
What was most remarkable was how the town overcame its many schisms. I discovered the town was split on many dimensions, geographically between old and new towns and into 12 sections each with its own youth head, hierarchically between young and old, chiefs and youths, politically on party lines, factionally on family loyalties and feuds especially between those loyal to the Fasuluku Sonsiama's and those who had been loyal to the Kaimondo's. The youth heads responsible for mobilising the men in their respective section, backed by the authority of the chiefs and other local authorities, succeeded in bringing the townspeople on board. All parties agreed the town would volunteer for two days work to start with, on the 6th and 7th of February, with the possibility of further days depending on how the work proceeded. An appeal was put out to the town for the loan of mining buckets to bail with, I also loaned out 10 shovels. We all reserved judgement until the date, as to whether the townspeople would turn up.
Clearing the Access Road - 3rd to 6th February 2014
While discussions were taking place in town I was negotiating with the transport company that usually delivered my building materials to Kayima. It seemed they were reluctant to take their truck up the road even if we cleared it. At first because it was too narrow and then because they were afraid the truck would get a puncture far away from any garage. I assigned several men to start brushing and widening the road, which took several days. Still the truck's head driver refused to use the road, citing sharp stumps and risk of punctures. When I inspected the road there were pointed stumps remaining but not strong enough to puncture a trucks tyres or even those of a normal four wheel drive (I tested this personally with my own vehicle). Most of the road was passable and had been widened but there were still bottle necks too narrow for a truck to pass. The truck was due to arrive from Koidu the day before the work was due to begin. It became a race to remove all stumbling blocks,
I decided to test out a petrol driven heavy duty multi-tool strimmer that I'd shipped from the UK and to lead by example on the road clearing. The strimmer was originally intended to assist with minor grounds maintenance and pruning of cocoa, coffee and cola trees. I also wanted to compare its output with traditional manual labour using cutlasses. This seemed like a good time to try it out. Using the lethal looking heavy duty metal rotary cutting attachment I started from the school. The original team were half a mile further up the road. While they had cut to widen the road, they had not cut right down to ground level, a special type of brushing which had its own name. The cutter dismissed smaller stumps with ease but had to work for a few seconds on anything above 40cm diameter, I had to concentrate to bring stumps to ground level while preventing the blade from digging in and sending earth flying. I made about 50 metres progress in the first hour before being joined by more volunteers.
As we progressed deeper, the number of stumps increased and in places overhanging branches had to be attacked to allow passage of a tall vehicle. Progress slowed down and it took several hours before we caught up with the two others working their way back from the Turntable end. An abandoned termite hill about a metre and a half wide and a couple of well developed trees that looked over 10 years old forced us to divert the road in a couple of places and expand the opposite side of the road. We eventually had 10 or more volunteers helping, I swapped the machine with one of them at their request and tried my hand at a cutlass. From childhood I remembered that the correct and skilful wielding of a cutlass for farm work was a matter of pride for men and women, I'm glad to say I didn't disgrace myself, although I realised I'd need to get a lot fitter if I ever wanted to clear an area of any size.
Despite having levelled all the spikes in the road and widening the road, the truck driver remained adamant. We were forced to consider a plan 'b' for delivery of building materials to the Turntable.
DAY 1 - 6th February 2014

The turnout was much better than we could have hoped for, in fact there was a shortage of tools and buckets to go around, teams took shifts bailing and shovelling out detritus.

Friendly jibes and a competitive spirit between the 12 sections ensued and motivated the rate of work. Over two days I found my self standing side by side conducting affairs with the head of the Kaimondo family, the two families had been hitherto sworn enemies, Kaimondo showed me a picture of my father when he was member of Parliament and the late PC Kaimondo sitting side by side just after the war. I figured if they could bury the hatchet enough to work together, so could we. I don't know how far they got or whether they actually did cooperate before they died, both in 2003, but here in 2014 with these dam works was tangible proof that it was possible and that good things could come from bouts of cooperation. I knew that the Kaimondo's could have tried to sabotage the whole initiative by not including themselves, thus deterring the other factions who may not have wanted to work if everybody didn't do their fair share. On the other hand they could have feared being left out. Perhaps they were motivated by the possibility of gaining prominence in the town, or losing face if they were not part of it. Of course the ideal motivation would be that they and everybody else genuinely felt both a sense of social responsibility and were worried about the state of the water they and their children were drinking.
---------------------------------------------------------------------
Summary: Project to mobilise local authorities and whole town of Kayima, to repair and renovate Kayima gravity fed water supply dam to correct heavily polluted water being drunk by towns people, reduce water borne disease, reduce annual soil incursion and increase water resilience through the dry season.
