| The Kenya Agricultural Research Institute imported 12,300 curculionid weevils (Neochetina spp.) from diverse sources, for biological control of water hyacinth in Lake Victoria, as part of the World Bank-funded Lake Victoria Environmental Management Project in East Africa. In addition to the rearing and quarantine facility at Muguga, a second rearing facility was established in 1996 at Kibos, near Lake Victoria. The Kibos rearing facility and two community rearing facilities at the lakeshores, have produced approximately 100,000 adult weevils and 42,000 weevil eggs over a three-year period. Since January 1997, some 73,500 Neochetina weevils have been released at 29 sites and an additional 10,000 redistributed at several sites. Visual observations and... |

| Previous studies by various agencies have shown that widespread erosion is occurring on the Nigerian shoreline and in some places, the rate of shoreline retreat is so rapid as to be alarming. Shoreline stabilisation methods adopted for combating erosion along our coasts have been counter-productive and, in many cases, aggravated the problem largely because such solutions had been, and are being, carried out without consideration or understanding of fundamental principles of shoreline dynamics and processes. Following a review of case histories, the Nigerian Institute for Oceanography and Marine Research initiated in September, 1981 a data acquisition programme aimed at making a scientific input into long term and large scale coastal management planing in... |

| The paper presents preliminary data collected in an assessment of the social, economic and environmental impacts of water hyacinth in the Lake Victoria Basin. A summary of the status of control and strategies for the future is given. The report draws on field observations made, studies through interviews of affected communities and organisations, personal communications and published reports by scientists in the region. Lake Victoria, the world’s second largest freshwater body, supports an estimated 25 million people living in the Basin, with an estimated gross economic product of US$3–4 billion annually, mainly from subsistence agriculture and fishing in Kenya, Uganda, Tanzania, and parts of Rwanda and Burundi. The multiple activities in the Lake Victoria... |
