Sammendrag
Gene flow by means of pollen and seeds in maize influences local, regional and global maize biodiversity. Developing countries are centers of diversity for maize and preserve seeds also in informal seed systems. Particularly in poor communities, seed saving and sharing often co-occur with farming on small fields. We present preliminary investigations from a small-scale maize farming community, in Chongwe, Zambia, to illustrate the significance of seed saving and sharing for patterns of gene flow. The potential introduction of genetically modified (GM) plants brings in new dimensions of challenges for farmers e.g. related to: i) co-existence of GM and non-GM varieties; ii) potential infringement of intellectual property rights; and iii) trans-boundary movement of products to countries that do not accept certain GM products. Small-scale farming is vulnerable to cross-contamination due to limited separation between fields. If transgenes are introduced into small-scale agricultural contexts, uncontrolled diffusion and further spread seems unavoidable. Removal of transgenes as well as the regulatory implications of transgenes would require control of innumerable small informal seed stores kept by farmers.
