The Uganda National Agricultural Research Organization has implemented conventional and biotechnology programs that seek improving bananas and address the crop’s most important pest and disease problems. A major thrust is the development of genetically modified (GM) bananas. The purpose of this paper is to examine potential social welfare impacts of adopting a GM banana in Uganda. The study has three objectives. First, suggest and apply an approach to calculate reversible and irreversible benefits and costs of introducing a GM banana. The study applies a real option approach to estimate, ex ante, the maximum incremental social tolerable irreversible costs (MISTICs) that would justify immediate introduction of the technology. Second, suggest an approach for assessing producer/consumer preferences and willingness to pay (WTP) for introducing a GM banana. Finally, the paper discusses main implications for biosafety decision making for GM crops in Uganda. Results of MISTICs estimation for different scenarios indicate that in delaying the approval of a GM banana, Uganda foregoes potential annual benefits ranging approximately from US$179 million to US$365 million. Average annual MISTICs per household vary between US$34 and US$ 69. Results indicate that only if the average household is willing to give up at least US$38 per year to avoid introduction of a GM banana, should postponing an immediate release be considered. Results imply that although GM bananas promise vast benefits, realization of those benefits depends on consumers’ perceptions and attitudes and the willingness to pay for the GM technology.

INTRODUCTION Banana is a staple crop in Uganda. Ugandans have the highest per capita consumption of cooking banana in the world (Clarke, 2003). However, banana production in Uganda is limited by several productivity constraints such as pests, diseases, soil depletion, and poor agronomic practices. To address those constraints, the country has invested significant resources in research and development and other publicly funded programs, pursuing approaches over both the short and long term. Uganda formally initiated its short-term approach in the early 1990s; it involves the collection of both local and foreign germ plasms for the evaluation and selection of cultivars tolerant to the productivity constraints. The long-term approach, launched in 1995, includes breeding for resistance to the productivity constraints using conventional breeding methods and genetic engineering. Genetic engineering projects in Uganda target the most popular and infertile cultivars that cannot be improved through conventional (cross) breeding. The main objective of genetic engineering in Uganda is to develop genetically modified (GM) cultivars that are resistant to local pests and diseases, have improved agronomic attributes, and are acceptable to consumers (Kikulwe et al., 2007). The introduction of a GM banana in Uganda is not without controversy. In Uganda, where the technology of genetic engineering is still in its infancy, it is likely to generate a wide portfolio of concerns, as it has in other African countries. According to the Uganda National Council of Science and Technology (UNCST) (2006), the main public concern is the safety of the technology for the environment and human health. Several countries have designed and implemented policies to address the safety concerns of consumers and producers (Beckmann, Soregaroli, and Wesseler, 2006a, 2006b). Such policies include assessment, management, and communication of the biosafety profiles of genetically modified organisms (GMOs) (Falck-Zepeda, 2006). As a consequence of its international obligations and the need to guarantee a socially accepted level of safety to its citizens, Uganda has taken significant steps to ensure the safety of GM biotechnology applications.

    Through the Zone of Nonbeing: A Reading of Black Skin, White Masks in Celebration of Fanon’s Eightieth Birthday* LEWIS R. GORDON Introduction anon was an ironic writer who was struggling with the complex question of paradoxical reason Fand paradoxical history. The modern collapse of “Reason” and “History” into all things European represented a failure of Reason and History that required self-deception regarding Europe’s scope. Put differently: Europe sought to become ontological; it sought to become what dialecticians call “Absolute Being.” Such Being stood in the way of human being or a human way of being. It thus presented itself as a theodicy. Theodicy is the branch of inquiry that attempts to account for the compatibility of God’s omnipotence, omniscience, and goodness in the face of injustice and evil. There are several formulations of the problem: If God has the power to do something about injustice and evil, why doesn’t He? If God has created everything, and God is perfect, how could God create imperfect (often evil) beings? If God has foreknowledge, how could we continue to insist on God’s goodness when He had advanced knowledge of the consequences of his creation? There have been many classical efforts to address this problem. The most influential has been St. Augustine’s insistence, in The City of God, that God’s love for humanity required human freedom, and freedom requires the ability to do right or wrong. The problem does not only emerge in the Western tradition. Among the Akan of Ghana, for instance, the problem emerges as well, and solutions similar to St.

  • History of the Banana
    History of the Banana Bananas: The Same The World Over Banana is the common name for the fruit and herbaceous plant that is part of the genus Musa. Bananas are one of the world’s oldest and most popular fruits. They are very nutritious, generally inexpensive, and readily available. The banana plant is a large flowering plant that grows 6–7 meters tall. Each plant produces a bunch of bananas from a flowering stem. Whether eating a ripe banana in the United States or in Europe, these store-bought bananas tend to taste the same. Part of the banana’s popularity is due to its predictably delicious flavor. However, the uniformity that makes the banana so popular could also lead to its demise. A bunch of bananas hangs from the main stem of the Banana History plant. As humans’ hunter-gatherer ancestors roamed the jungle collecting food, they ignored the bananas they found. Wild bananas, which flower and reproduce sexually, produce hard seed cases with inedible seeds inside. Occasionally, prehistoric humans found fruit on wild banana plants that did not contain seeds. These seedless bananas, when peeled, contained sweet, edible flesh. This is the edible banana that people know and enjoy today. Today’s edible banana is a genetic mutation. The mutation produces tasty fruit but prevents proper seed development. The dark lines sometimes seen after biting into a banana are the stunted seeds. Banana Sexual Reproduction In nature, bananas reproduce through sexual reproduction. Sexual reproduction in flowering plants is similar to sexual reproduction in animals. Sperm cells are produced inside pollen grains.

  • Musa Acuminata (Banana, Edible Banana) Size/Shape
    musa acuminata (Banana, Edible Banana) Banana is short lived herbaceous plants with large rhizomes. Banana recognized by its large, fleshy, upright stalks topped with soft, smooth, arching leaves. Ranging from 1 m for the dwarf species to over 5-6 m for the largest types, Banana ''trees'' are guaranteed to lend a tropical flavor to any landscape setting. The broad, tender leaves are easily torn by winds and plants should be located in a sheltered area to prevent this. The unusual reddish-purple flowers are followed by clusters of upwardly-pointing green fruit, maturing to a beautiful yellow. After the fruit appears the plant dies back. If we cut the trunk back until the ground new growth will appear. Growing best on fertile, moist soil, Bananas will thrive in full sun or partial shade and should be protected from both wind and cold. Plants respond well to regular fertilization. Many different species of Banana are available. Some ornamental types are grown for foliage or flowers. The best usages for Banana as a specimens or container plant.

    Article Accounts of injury as misappropriations of race: towards a critical black politics of vulnerability MICHEL, Noemi Vanessa Abstract Across contexts and time, subjects marked by racial difference have expressed public accounts of the multiple injuries of race. From the vantage point of critical race and black theory, this paper sheds light on both the heuristic and critical political values of such accounts. The first part critically reassesses conceptualizations of vulnerability as an ambivalent ontological condition within critical approaches to liberalism. A close reading of Fanon's account of injury in Black Skin, White Masks specifies how race exploits bodily and enunciative vulnerability and materializes subjects into a state of suspension and suspicion. The second part addresses the political promise of accounts of racialized injury. Departing from sceptical readings of “wounded attachment,” critical race and black analyses associate accounts of injury with citational practices that pertain to historically entrenched conventions of resistance to racial and colonial abusive power. Such accounts can be read as misappropriations of race which expand the horizon of the human. Reference MICHEL, Noemi Vanessa.

  • Evaluation and Utilization of Different Banana
    SCREENING FOR POTENTIAL UTILIZATION OF DIFFERENT BANANAS AND PLANTAINS FOR CHIPS PROCESSING Lydia P. De Leon and May P. Loquias Bureau of Plant Industry - Davao National Crop Research and Development Center, Bago Oshiro, Davao City ABSTRACT Screening for the potential utilization of bananas and plantains for chips processing was conducted on January – December 2009 at the Bureau of Plant Industry – Davao National Crop Research and Development Center, Bago Oshiro, Davao City. Seven dessert and fourteen cooking varieties were evaluated. Through sensory evaluation, the acceptability of the different varieties of bananas and plantains for chips processing was determined. Statistical analysis showed no significant differences among the varieties in terms of taste, color, crispiness and overall acceptability. But numerically, chips from FHIA 17 and FHIA 18 were the most acceptable among the dessert varieties and chips from “Inambak” were the most acceptable among the cooking varieties. Among the dessert varieties, Kluai Namwa Khom gave the highest chips recovery rate of 40.0 percent per kilogram of raw unripe fruits and among the cooking varieties, “Tindok” gave the highest chips recovery rate of 61.6 percent. Having bigger bunches and fruits, FHIA 17 gave the highest computed chips yield among the dessert varieties of 9.72 kgs per bunch. Among the cooking varieties the Check variety “Cardaba” gave the highest chips yield of 11.00 kgs per bunch. Small-bunched but big-fruited, “Tindok” also gave higher chips yield per bunch of 7.39 kgs. Having a shorter planting to harvest period, higher chips yield per bunch, higher overall acceptability and consumers’ preference, the use of the cooking plantain “Tindok” for chips processing, early return on investment could be realized.

Genetic improvement of these bananas for resistance to pests and diseases has been a priority breeding objective. However, there is insufficient information on fruit quality characteristics that different users prefer, resulting in sub-optimal adoption of new varieties. This study identified matooke characteris- tics preferred by farmers and traders, using survey data from 123 farmers, 14 focus group discussions and 40 traders. Gender differences were considered. The main characteristics that were found to drive variety preferences were agronomic (big bunch, big fruits) and quality (soft texture, good taste, good aroma, yel- low food).
