    Parables: applied economics literature about the impact of genetically engineered crop varieties in developing economies

    "A vast literature has accumulated since crop varieties with transgenic resistance to insects and herbicide tolerance were released to farmers in 1996 and 1997. A comparatively minor segment of this literature consists of studies conducted by agricultural economists to measure the farm-level impact of transgenic crop varieties, the size and distribution of the economic benefits from adopting them, consumer attitudes toward GE products, and implications for international trade. This paper focuses only on the applied economics literature about the impact of transgenic crop varieties in non-industrialized agricultural systems, with an emphasis on methods. A number of studies have surveyed the findings for both industrialized and non-industrialized agriculture, at various points in time, but surveys of methods are less frequent and have typically examined only one overall question or approach. Clearly, the methods used in research influence the findings that are presented and what they mean. Understanding the methods therefore enhances understanding of the findings. Four categories of impact analysis are considered: farmers, consumers, industry and trade. In part due to methodological limitations and the relatively brief time frame of most analyses, results are promising, but the balance sheet is mixed. Thus, findings of current case studies should not be generalized to other locations, crops, and traits. The aim of this review is to progress toward the defining a “best practices” methodology for national researchers who seek to produce relevant information about emerging crop biotechnologies for national policymakers.

    Acceptance of biotechnology and social-cultural implications in Ghana

    Despite major scientific progress in the application of biotechnology in agriculture, public attitudes towards biotechnology in general and genetically modified food (GM food) products in particular remain mixed in Africa. Examining responses on acceptance of GM food through a stakeholder survey in Ghana, it was established that half of the 100 people sample interviewed were not in favor of GM foods. To this group acceptance of GM foods would make farmers loose focus on the traditional ways of cultivation, putting the whole nation at the mercy of profit driven foreign companies who produce GM foods. In order to have clear and unbiased attitudes towards agricultural biotechnology in Africa, there is the need to substitute dominant ideologies in the way biotechnology research and dissemination are conducted in developed countries with tailor-made methodologies in developing countries. This paper emphasizes the social dynamic force of food focusing on the need for social shaping of biotechnologies to reflect local and regional needs. Respondents’ perceptions of GM foods suggest that food is seen as not just a commodity to be consumed but food has both cultural and national identities. Generally, people are identified by their consumption and nutrition lifestyles and therefore take pride in what they eat. A proposal is made to set biotechnology research agenda in the context of social choices; social scientific coalition of biotechnology with endogenous development pathways’ as opposed to ‘exogenous biotechnology research’. Also there is the need for adequate capacity building of the existing regulatory institutions to handle ethical and moral issues associated with biotechnology research since survey findings showed lacked of public confidence in them.Biotechnology; survey; acceptability; social shaping; Ghana

    Training them to catch fish? Farmer education and training programmes in Uganda’s organic agricultural subsector

    Get PDF
    This policy brief explores the nature of training and education activities of civil society organisations and tertiary institutions in Uganda. An internet search of the training and education activities in organic agriculture in Uganda shows overwhelming indications of the hard work that is being put into educating and training Ugandans. Critical questions therefore arise: ‘What is driving these training and education programmes?’ ‘Who is running these programmes and what are their focus areas?’ and, ‘Qualitatively speaking, how effective are these programmes?’ Using the analogy of ‘train them to catch fish’, the policy brief grapples with answering these complex questions. Recommendations are made to both civil society and the Ugandan government on strategies to carry forward the process of growing the sector

    Use of genetically improved and alien species for aquaculture and conservation of aquatic biodiversity in Africa

    Get PDF
    Aquaculture species are being domesticated and improved through genetic enhancement. Despite the benefits of improved fish in terms of increased production, there are risks associated with conservation of biodiversity when the introduced strains/species escape in natural waters. This is especially important in Africa which is one of the worldÆs repository of diverse freshwater fish fauna and home to native tilapias. This proceedings is a useful tool in bringing awareness among African institutions, agencies, planners of the issues involved in improving production through introductions of improved strains/alien species while sustaining the biodiversity.Aquaculture, Tilapia, Selective breeding, Brood stocks, Biodiversity, Quarantine regulations, Introduced species, Resource conservation, Africa,
