<A Special Report By Leo Odera Omolo
After almost a decade of efforts to rid Lake Victoria of water hyacinth, a report by the Kenya Marine Fisheries Research Institute now says the noxious weed offers enough production of handcrafts, furniture and households accessories.
The report based on a study conducted in the Nyanza Gulf shows that the weed covers about 1,400 hectares of the water mass on the Kenyan side of the Lake.
The weed has hampered the activities of fishermen using small home made canoes, motorized boats and the navigation of ships become a nightmare in some areas. It has blocked the access to many fish landing beaches and made life difficult for fishermen fish and trade more difficult in recent years.

Among the items proposed to be made from hyacinth fiber are lamp shades, picnic baskets, place mats, napkin holder and floor mats as well as waste bins, file folders, stack trays pen holders and desk organizers
Others are livestock feeds, fish food, fuel paper and building materials.
The institute also says the hyacinth can be put to agricultural uses such as making of mulch, fertilizer and weed control
The report notes that conventional methods of controlling the water hyacinth and other intrusive aquatic plants are expensive for development countries. This is to be able to convert the biomass of water hyacinth to useful purposes instead of accepting the costs of its destruction is importance for the economy of developing countries the report concluded.
In suggesting Industrial use of the weed, however the report also proposes that surveys should be conducted to identify potential markets such as stationery shops outlets, exhibitions and road side outlets among others.
Marketing challenges have in the past hampered attempts to harness the noxious weed. A number of self help groups around Lake Victoria have produced handcrafts and house hold accessories before but the enterprises could not be sustained.
The report says it will be necessary to train the local community on the production of the different items and also how to sustain production.
Another consideration is the establishment of production units near the Lake shore which should feature factories complete with show rooms.
The report also points out that availability and harvesting of the weed depends on seasons and wind direction. The scientists say that the mats of the water hyacinth are blown to various beaches in the gulf in different seasons creating two kinds of hyacinth population, the stationery one in sheltered bays and the mobile one that are blown around by the wind.
These would require development of different strategies for harvesting, for the mobile mats , the weed would be harvested manually using sickles and transported using canoes to the shore, while the stationery mats can be harvested from land , says the report.
The harvesters will nevertheless face danger from the crocodiles, snakes, and hippos that live in the Lake. They will need special body gear and gloves for protection against water borne diseases such as bilharzias and liver flukes organisms. Big Industrial harvesters will require excavators capable of harvesting up to one hectare per day.
The reports further says that harvesting of the weed for Industrial use will help reduce the amount of rotting weed that suck oxygen from the water starving aquatic life of dissolved oxygen.
Moreover the researcher argue, harvesting of the weed will contribute to the water purification process because once it is uprooted it takes away with it absorbed pollutants
The study was commissioned by the woman in fisheries project and the scientist visited eight bays in the Nyanza gulf to determine the distribution, quality, quantity, and reliability of the water hyacinth as a resource for Industrial production.
Using the global positioning system, they estimated that Asembo, Nyakach and Osodo bays had the largest mass of the weed for utilization, Kisumu and Mirunda bays had the least.
Other areas covered by the study was Homa-bay, Kendu-bay and Lambwe valley..
