| Starting from a small base, aquaculture production in Africa registered annual growth rates equal to or above those in other regions. This expansion was due to signifi cant increases in a few African countries. Increasing demand coupled with rapidly dwindling catches from capture fi sheries, the implementation of novel participatory approaches to technology development and transfer, and the emergence of a few successful large-scale tilapia culture operations directed at the export market offer opportunities for further expansion in both the small-scale and large-scale commercial sectors. Existing biotechnical, economic and institutional challenges, which include lack of national policies to guide aquaculture development, unfriendly investment policies, the... |

| Even though much improvement has been made in plant transformation methods, the screening of transgenic plants is often a laborious work. Most approaches for detecting the transgene in transformed plants are still timeconsuming, and can be quite expensive. The objective of this study was to search for a simpler method to screen for transgenic plants. The infiltration of kanamycin (100 mg/mL) into tobacco leaves resulted in conspicuous chlorotic spots on the non-transgenic plant leaves, while no spots were seen on the leaves of transformed plants. This reaction occurred regardless of age of the tested plants, and the method has proven to be simple, fast, non-destructive, relatively cheap, and reliable. These results were comparable to those obtained by the... |

| Development of genetically modified crops is challenging the functions of the grain marketing system with many participants arguing for Identity Preservation systems prior to release of GM varieties. In this study, a stochastic optimization model was developed to determine optimal testing strategies. The model chooses the optimal testing strategy that maximizes utility (minimizes disutility) of additional system costs due to testing and rejection and allows estimation of the risk premium required for sellers to undertake a dual marketing system with GM/Non-GM segregations over the current Non-GM system. Elements of costs (testing costs, rejection costs, and risk premium) were estimated for a base model representing a grain export chain. The model... |

| This paper analyzes the current and proposed biosafety systems in Kenya, Tanzania, and Uganda using a set of components and characteristics common to functional and protective biosafety regulatory systems. It also assesses how those systems take into account the major international legal obligations that relate to biosafety, such the Cartagena Biosafety Protocol. The paper identifies certain areas in each country’s biosafety regulatory systems where further development and clarification would improve the biosafety system, making it more functional and protective. Those areas include: (1) the addition of procedures to ensure the food safety of genetically engineered organisms; (2) the inclusion of the standard and criteria for making an approval decision;... |
