| 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. |

| This paper considers vulnerability reduction in Sub-Saharan Africa (SSA) from a more aggregated macro viewpoint. We focus on risk related to agriculture, since vulnerability and agriculture are intimately linked in SSA due to the location of the poor, their dependence on agriculture and the inherent risks of an agricultural livelihood. We argue that agricultural growth is one of the most effective means for improving permanent incomes and reducing vulnerability. However, agriculture is not homogeneous, and the inherent risks vary across countries and regions. Therefore, we also discuss appropriate investment strategies and policy instruments for different sets of risks. |

| Smallholder farmers operate in vertical supply chains. Therefore, an understanding of key opportunities and constraints up through the value chain becomes necessary for sustaining smallholder growth. Yet market analysis is of little value unless key private and public sector stakeholders agree to implement necessary reforms. This paper advocates an approach which marries together value chain analysis with a stakeholder taskforce to ensure that analysis of opportunities and constraints gets translated into actions that will facilitate commercial growth. Using Zambia’s cassava task force as an example, the paper describes the value chain task force method and identifies elements critical to its effective implementation. |

| AGOA directs the President of the United States to convene an annual meeting between the U.S. government and representatives of eligible African countries and to prepare an annual report to Congress on U.S. trade and investment policies with sub-Saharan Africa (SSA). Currently, Angola, Gabon, Nigeria and South Africa- accounted for the bulk (84 percent) of U.S. total imports from SSA. Since the passage of AGOA, the business climate has improved for non-agricultural exports and growth in these sectors has made relatively low direct benefits to Africa’s poor. Consequently, expanding AGOA’s application to African agriculture would have a significant impact on reducing hunger and poverty and therefore, on improving overall conditions in SSA. As a result of... |

| The African Region consists of 48 countries and five island nations, most of which are practising some form of aquaculture, often at a very low level. Over half the countries report producing less than 100 mt annually. The largest producer is Nigeria (17 700 mt) followed by Madagascar (5 100 mt) and Zambia (4 700 mt). The 1997 combined aquaculture production of the region was 40 300 mt. Aquaculture is estimated to be 95 percent small scale, with fish ponds integrated into the mosaic of agricultural activities. Mean yield is approximated as 500 kg/ha/yr, although the range is wide, from less than a hundred to more than 10 000 kg/ha/yr. A typical scenario would be a 300 m2 pond producing 15 kg a year relying on family labour and on-farm inputs. There is... |

| During recent two decades the world has witnessed a drastic increase in global FDI inflows. Gradually more and more investment has been directed to the developing countries in the attempt to diversify portfolios and use finance in the most efficient way. Not all developing regions of the world perfectly succeeded in attracting FDI. Large by labor force and territory, abundant in natural resources Sub-Saharan Africa could perform much better in this aspect. This paper once again reviews the opportunities for FDI in Africa and suggests possible ways for authorities of African states to overcome the existing situation. |
