Based on the findings of this study, the following actions are proposed for consideration by the Government of Kenya: 1. Raise public investment in maize seed breeding and agronomic research to make it possible for improvements in smallholder crop productivity. Based on research evaluating the returns to alternative investments in agriculture, public expenditures in maize seed breeding and agronomy may constitute the single most important investment to promote broad-based productivity growth and poverty reduction in Kenya. 2. Explore options for improving public and private extension programs to enable farmers to adopt improved farm technologies generated from point 1. 3. Examine options for bringing more land in Kenya under potential cultivation by... |

An isolated pterosaurian caudal cervical (~ postcervical) vertebra was recovered from the Upper Cretaceous Lapurr sandstone ofWest Turkana, northwestern Kenya. The vertebral centrum is short, wide, and dorsoventrally compressed. Although the specimen is lightly built similar to most pterosaurs, it is here referred to Pterodactyloidea and tentatively to the Azhdarchidae in that it lacks pneumatic features on both the centrum and neural arch. This represents one of the few pterosaurs recovered from the entirety of Afro-Arabia, the first pterosaur recovered from the Cretaceous of East Africa, and, significantly, a specimen that was recovered from fluvial deposits rather than the near-shore marine setting typical of most pterosaur discoveries. |

Pearl oysters are an important marine resource within the Indo-Pacific oceans. They are widely cultured for the production of black pearls, their flesh is eaten, and their shell, known as mother-of-pearl (MOP) is used in the ornament and button industry. The blacklip pearl oyster, Pinctada argaritifera L., has been harvested from East Africa for MOP for decades. A survey within nearshore habitats in Kenya showed that Pinctada margaritifera is widely distributed in shallow lagoons, bays and channels. Other oyster species found during the survey were the wing oyster, Pteria penguin, occurring in deep channels in Shimoni and Mombasa, and Pt. chinensis, within lagoons and channels in Malindi, Mombasa and Shimoni. Pinctada margaritifera was most abundant in... |

Maize is the major food crop grown in the coastal region of Kenya and constitutes a major component of the diet of the population in the region. However, average yields are far below the potential for the region and low production levels create serious food deficits. Over the years, new technologies have been introduced but adoption has remained low, especially for fertilizer. This paper examined current maize-farming practices and technological and socioeconomic factors that influenced adoption in the Kilifi and Kwale Districts of the Coast Province, that together account for half of maize production in the region. The study found low adoption levels for improved maize varieties and technology, especially fertilizer, among farmers in the area. Farmers... |

A consensus exists that extension services, if functioning effectively, improve agricultural productivity through providing farmers with information that helps them to optimize their use of limited resources. Variations in management practices and husbandry skills among small farmers in Kenya are very great. Tremendous poverty-reducing benefits could be reaped by bringing the production costs of the most inefficient farmers to mean productivity levels. Achieving these gains in maize production efficiency will depend on many factors, but extension is likely to be among the most important. Therefore, the costs to the nation of having an underperforming extension service – in terms of smallholder productivity, incomes, and poverty reduction, and the ability... |

The paper has several specific objectives. First, it identifies how fertilizer marketing costs and the types of fertilizers used have changed over the course of the liberalization process in Kenya. A second objective is to examine the fertilizer subsector in Kenya with a view to identifying organizational and institutional changes that could improve its performance. Various types of fertilizer supply chains serving farmers in western Kenya are identified, examine the cost structure of these supply chains, identify potential sources of cost reduction in these supply chains, and last, estimate the impact of illustrative scenarios for reducing fertilizer marketing costs on the profitability of maize production in western Kenya. |

Kenyan horticultural exports are often cited as a success story in African agriculture. Fruit and vegetable exports from Côte d’Ivoire have received less attention, but the export value is similar to that of Kenya. This paper focuses on three questions. First, do the horticultural sectors of Kenya and Côte d’Ivoire constitute valid success stories? Second, what factors have contributed to the success (or lack thereof)? And third, to what degree can the success be replicated in other African countries? The paper finds that Kenyan horticultural exports are indeed a success story: horticulture has become the third largest earner of foreign exchange, more than half the exports are produced by smallholders, and smallholders gain from producing for the export... |

Market-based development efforts frequently create opportunities to generate income from goods previously produced and consumed within the household. Production within the household is often characterized by a gender and age division of labor. Market development efforts to improve well being may lead to unanticipated outcomes if household production decisions are non-cooperative. We develop and test models of household decision-making to investigate intra-household decision making in a nomadic pastoral setting from Kenya. Our results suggest that household decisions are contested, with husbands using migration decisions to resist wives ability to market milk. |
