The size of the community
Kikuyu town has a high population density and the current figures are about 500 persons per kilometer square. Since land is a very important factor of production, it is divided into small portions on which permanent and semi-permanent residential houses are built.
What surrounds the swamp?
Local farmers who grow horticultural crops, livestock rearing, learning institutions, government department, and the civil society institutions surround Ondiri swamp.
Pollution in the swamp
There are extensive deforestation and destruction of the ecosystem, use of fertilizers and other inorganic manures by local farmers leading to the growth of algae in the swamp. Pesticides also find their way into the swamp causing pollution. The town lacks a sewer system and there is a likelihood of pollutants seepage from septic tanks. There is also the dumping of solid waste and uncontrolled water abstraction. The swamp is set on fire to generate new forage; a huge smoke is visible in the sky, which pollutes the air too.
Is the swamp being used in the wrong way?
There is an uncontrolled abstraction of water from the swamp for irrigation of farms and for domestic use. The water pumps around the swamp are not metered which makes it hard to predict the amount of water being abstracted. Some people also harvest macrophytes for livestock forage to be used domestically or commercially, this is done by setting up the fire in the swamp to generate new forage. This in return kills the important microorganisms in the swamp. A macrophyte is an aquatic plant that grows in or near water and is either emergent, submerging, or floating, and includes helophytes (a plant that grows in marsh, partly submerged in water, so that it regrows from buds below the water surface). Microorganism is an organism that can be seen only with the aid of a microscope and that typically consists of only a single cell. Microorganisms include bacteria, protozoans, and certain algae and fungi.
The swamp does not necessarily attract safaris but some people go there for bird watching and use it as a recreation site. Some people also flock the swamp because they believe the water has a healing and soothing power.
Projections about drying up of the swamp due to climate change if the community are not aware
Yes, too much water abstraction for greenhouse farmers and the presence of eucalyptus trees planted too close to the edge of the swamp threatens the existence of the swamp and may lead to drying up if something is not done. Recently during the world wetlands day, the friends of Ondiri swamp planted some indigenous tree species to conserve the swamp this was a great move.
