The relationship between crop genetic diversity, food security and farm household well-being has received extensive study from economists. Public investments in research and development of improved crop varieties under the green revolution resulted in increased agricultural production and capacity to feed the growing population, but the effects from increased research and development have not been uniform. There are still considerable areas in the world where low rates of agricultural productivity give rise to poverty and food insecurity. Bruinsma (2003) estimates that agricultural intensification will be the primary source of crop production growth globally over the next 25 years. The same report showed estimates of the potential attainable yield with existing technologies compared with actual yields for rainfed wheat production in Ethiopia and indicated the presence of a significant gap of approximately 2.8 tonnes/hectare. An important aspect of narrowing the gap involves improving the management of crop genetic resources. (Bruinsma 2003) Empirical evidence also indicates that in countries with high dependence on agriculture such as Ethiopia, giving priority to food production is a promising means of increasing nutritional levels and reducing food security.
