“…We also note that for the 2008 data there are clear indications that households closer to the lake are better off than those far away from the lake, which is in line with a previous study. Geheb et al (2008) found substantially lower rates of child malnutrition in households within 25 km of the lake compared to those in the range 25-35 km from the lake. Salaam.…”

“…Geheb et al (2008) have a more micro level approach using health data on occurrence of malnutrition, and strongly reject the claim that there is a direct linear relationship between Nile perch export and the high frequency of malnutrition among population in lake regions of all three countries surrounding the lake. They also stress that exporting food does not imply taking away the food per se, "It is cash and the way this is distributed within households that matters…" (Geheb et al, 2008, p.88), further they found that fishermen unanimously held that factories had been beneficiary for their business and had led to higher prices.…”

“…Brown et al (2005b) also discuss how changing fishing patterns may have a strong gender effect as females are much more involved in catching and handling dagaa and haplochromis, compared with Nile perch fishing which primarily imply work for males. Geheb et al (2008) also focus on the gender issue and hold that it is a major reason for the high frequency of malnutrition around the lake, household income have increased but is more unequal within households. Smith et al (2003) is another study emphasizing the gender aspect, which claim that improving the status of women vis-à-vis men likely improves nutrition of children.…”

“…Recommending policies is beyond the scope of this study. Geheb et al (2008) provide an insightful discussion in favour of improving the status and income of women, while Béné et al (2010) primarily promote the development of regional trade (Africato-Africa) as a means of improvement.…”

“…Particular worry is given to the poorest part of the world, i.e. Sub-Saharan Africa, where there is an ongoing debate about whether liberalizing fish trade has pro-poor effect or leads to negative effects on local populations' food security and welfare development (see also Geheb et al, 2008;Abila, 2003;Jansen, 1997).…”

In this paper we examine the welfare implications of the Tanzanian fisheries boom following from the increase in quantities and prices of the Lake Victoria Nile perch export during [1993][1994][1995][1996][1997][1998][1999][2000][2001][2002][2003][2004][2005][2006][2007][2008]. We use the theoretical model by Brander and Taylor (1997) that we try to test empirically.We have a micro level perspective using data from a 1993 World Bank household survey and our own study from 2008, both containing data from about 520 households in the two regions Mwanza and Mara by the lake. Our results indicate that average income has increased in both rural and urban areas. For the poorest part of the population, rural areas experienced only modestly and non-significantly reductions in the fraction below basic needs, while urban areas had a substantial reduction. However, growth was modest and inequality seems to have increased during the period. Concerning human capital measured as education for the household head we found substantial improvements in educational level and a simple regression model confirmed the significant impact of education on household income. We also found that households on average are better off when situated close to the lake. Acknowledgement

Threats to aquatic biodiversity and possible management strategies in Lake Victoria

Lake Victoria is the second‐largest freshwater lake in the world, with a surface area of 68,800 km2. The lake is rich in natural resources that are essential to the local economy and livelihoods. However, International Union for Conservation of Nature (IUCN) ranks 76% of freshwater species endemic to the Lake Victoria Basin as threatened with extinction. The biodiversity richness of the lake is still diminishing, and the risk of species extinction is increasing. Many species are yet to be identified, and thus the number of species threatened with extinction exceeds what is currently known. Furthermore, the lake is home to species that are found nowhere else on the planet, but its protection is never given the attention it needs. Genetic diversity loss is harmful to future populations and influences sustainability of the ecosystem. The decline in Lake Victoria's biodiversity is primarily attributed to various pressing issues, including water pollution, invasive species, climate change, overexploitation and the challenges stemming from high human population density. These problems are exacerbated by inadequate regulatory enforcement and a lack of comprehensive data and information to inform and guide conservation efforts. If these factors are not addressed, they may have a detrimental impact on Lake Biodiversity. This article aims to document the main threats to aquatic biodiversity as well as potential management strategies for preventing further losses of the aquatic biodiversity in Lake Victoria. The study recommends reviewing, bolstering and reinforcing the rules and regulations governing the extraction, accessibility and discharge of nutrients into the lake. The national governments should work with local governments, non‐governmental organizations and local people to safeguard and conserve the lake's biodiversity. The national governments of the riparian nations should also reserve funds each fiscal year specifically for research that would inform effective management measures to prevent further losses of the lake's biodiversity.

Another potential disaster? On a proposal to introduce Nile perch, Lates niloticus, into Lake Kariba (Zambia/Zimbabwe)

The introduction of Nile perch, Lates niloticus, into Lake Victoria resulted in a massive increase in fish catches, but with significant ecological costs. These included the near extirpation of the 500+ endemic haplochromine species and the eutrophication of the lake. A proposal to introduce Nile perch into the artificial Lake Kariba (Zambia/Zimbabwe) is of concern, therefore, because of potentially adverse impacts on its fisheries and biodiversity. It is very unlikely that Nile perch would improve the fisheries in Lake Kariba, as it did in lakes Victoria and Kyoga, because this lake is oligotrophic and much less productive. The principal fishery in Lake Kariba is already in difficulty, owing to overfishing, and Nile perch could reduce catches further. The biomass of other native fish species is very low and would be unlikely to support a significant Nile perch population. Lake Kariba has already experienced a major loss of biodiversity as river‐adapted fish species have not been able to adapt to lacustrine conditions. The non‐native Nile tilapia, Oreochromis niloticus, has also replaced the endemic tilapia species in the middle Zambezi system and the Nile perch could bring about a further loss of biodiversity. The ecological costs of its introduction into Lake Kariba would not be justified by an increase in fishery productivity, and the possible introduction of Nile perch should be forcefully rejected.
