On 14th March 2017 I left my home village-Kiaritha and headed to Kangaita Village from where my second visit to various water projects would start. This is a journey that started a while ago. See this link:
A look at the Kenya
National Water Development report 2005, prepared for the 2nd UN
World Water Development Report ‘Water: A
shared Responsibility’ (2006), Kenya is classified as a water scarce country
with only 647 cubic meters of renewable fresh water per capita. The same is
characterized by high spatial and temporal variability and extremes of droughts
and floods. Water resources contribute enormously to the economic productivity
and social well being of human populace as both social and economic activities
rely heavily on the quantity and quality of water.-Professor George O. Krhoda.

In our context and as
Professor George O. Krhoda noted, we have reached to a point where availability of water is a
limiting factor for development in Kirinyaga County. Whereas the prevailing
weather conditions have played a role in the existing problem, I would want to
look at Rivers whose source is Mt Kenya
Forest. Mt Kenya Forest as a water tower (199,558 Ha, 12.1%) is the second
largest water tower after the Mau Complex (400,000 Ha,24.5%)- Kenya National
Water Development report 2005,Pg 202. Mt Kenya Forest water catchment
area must be properly managed so as to retain it’s capacity to supply good
quality water all year round.
Effects of Human activity on this Catchment area.
A look at the human activities along Rivers
Thiba, Mukengeria, and Kiringa paints a grim picture of what our future will look like. The Fencing of Mt
Kenya Forest may have been a great move but what happens inside the forest
offers no much hope in the long run.
For a legal*/Illegal* fee, one
can get into the forest to collect firewood but there is more than collecting
this precious commodity. From my sources, i was informed that deep inside the forest, illegal logging, charcoal
burning and poaching still goes on but to my surprise, my guide told me
that the Kenya Forest Service officers are aware of such activities as this illicit trade adds some extra coins in their pockets. The target species in this illicit trade are
the hard wood trees that are used to make highly priced timber whereas others
are used for wooden posts that are smuggled out of the forest at night at the
cost of Ksh 120-150 but fetch Ksh 250 once successfully smuggled into the
timber yards. The Long term effect of cutting down these trees will
be that the rivers will start drying right from the source.
(The other sad thing
that I heard is that some women who come to fetch firewood here are often sexually harassed (sex for firewood) and even raped
but these cases are rarely reported. This is the same fate that befalls girls
who are arrested inside the same forest especially when schools are closed) Let me
leave it at that point as these allegations are unconfirmed.
Flow modifications.
The uncontrolled commissioning of water projects along the rivers has had a negative impact on the natural
flow of the rivers downstream. Dams alter the flow, temperature and sediment in river systems.
Reduced flow alters aquatic habitats – reducing or removing populations of
fish, invertebrates and plants that
depend on the flow to bring food. Reduced flow also decreases tributary stream flow, changing habitats and
altering the water table in the stream aquifer.
Consequently, riverside vegetation may be
affected and decline in numbers. This may affect animal biodiversity, for
example, bird species may leave the area if their habitat is lost or altered.- https://www.sciencelearn.org.nz/resources/440-human-impact-on-rivers
The above means that
there are Water projects downstream that are solely drawing water from
tributaries which mean that we have areas along the river that are completely dry as a result of such
projects-Case of Kiganjo project along River Rutui. This also means that other
people who were to benefit from natural flow of rivers end up suffering from
lack of water which is a possible source of conflict if the prevailing drought
situation persists. One of the affected farmers shared with me his pains where
he noted that that he is suffering yet the river flows right next to his shamba. Arrow roots that used to grow by the river banks are no more hence no food or source of revenue for people downstream and as a researcher notes:
Rivers are connected systems, and barriers such as dams, culverts and
floodgates disconnect one area from another,notes siencelearn.org.nz
Along the river banks the blue
gum tree has been planted in numbers despite an order by the authorities that such trees be cut down and the effect has been that the
river beds that used to ooze water are no more doing so.
Existing studies show that the blue gum tree
reduces water yield and depletes soil moisture
especially during dry weather compared to natural grass land that is fast
disappearing along the rivers beds. As if this is not enough the already
diminishing resource has been subjected to ever increasing water projects that
are not sustainable all year round as we even came across abandoned projects.
The remaining projects are running far below capacity as some of them are
relying on water from small ‘wells’ along the river banks. Remains of logs that
may have been ferried by water downstream are still visible which is a sure
sign that water volumes usually get high and the current situation may not be a
reflection of what these rivers are when the rainy season comes.
Another notable trend is
that more land is being reclaimed for farming along the river banks and the
long term effect will be disastrous. The clearing of forests to produce
farmland has led to on-going erosion,
with large quantities of sediment
deposited into rivers. Agricultural intensification (substantial increases in fertiliser application and increased stock
numbers) has resulted in nutrient and
chemical loss to nearby streams and rivers. Elevated nutrient concentrations
(especially nitrogen and phosphorus – key components of fertilisers) can result in the eutrophication of slow-moving waterways.- https://www.sciencelearn.org.nz/resources/440-human-impact-on-rivers
Our visit revealed that
there are opportunities for tourism that are yet to be exploited
especially inside the forest where these rivers offer scenic views,sport fishing opportunities, hiking
and general adventure if we prudently use this resource.
A look at
the Kirinyaga County Government website reveals that there exists a Ministry of Water, Environment and Natural resources- http://www.kirinyaga.go.ke/environment.html but did not see any water resources management master plan in here.
Human impact on rivers is large-scale process that leads to diverse negative consequences.
There are following ways of such impact:

We are constantly being bombarded by problems that we face and sometimes we can get completely overwhelmed.
The story of the hummingbird is about this huge forest being consumed by a fire. All the animals in the forest come out and they are transfixed as they watch the forest burning and they feel very overwhelmed, very powerless, except this little hummingbird. It says, ‘I’m going to do something about the fire!’ So it flies to the nearest stream and takes a drop of water. It puts it on the fire, and goes up and down, up and down, up and down, as fast as it can.
In the meantime all the other animals, much bigger animals like the elephant with a big trunk that could bring much more water, they are standing there helpless. And they are saying to the hummingbird, ‘What do you think you can do? You are too little. This fire is too big. Your wings are too little and your beak is so small that you can only bring a small drop of water at a time.’
But as they continue to discourage it, it turns to them without wasting any time and it tells them, ‘I am doing the best I can.’
And that to me is what all of us should do. We should always be like a hummingbird. I may be insignificant, but I certainly don’t want to be like the animals watching the planet goes down the drain. I will be a hummingbird, I will do the best I can.
