Crop diversity between 20 and 90 percent crop losses in the Congo. The FAO emergency relief and rehabilitation program is assisting vulnerable returnee populations in the African Great Lakes Region through mass propagation and distribution of CMD resistant or highly tolerant cassava. A well known occurrence of disease susceptibility in crops lacking diversity concerns the 'Gros Michel', a seedless banana that saw world marketing in the 1940s. As the market demand became high for this particular cultivar, growers and farmers began to use the Gros Michel banana almost exclusively. Genetically, these bananas are clones, and because of this lack of genetic diversity,
Agriculture in Panama made land titling more necessary. Moreover, insecure tenure has been a particularly severe constraint to improved techniques and to commercial crop production. The cost of titling a piece of land has been too high for most subsistence farmers. Between 1969 and 1977, the government attempted to redistribute land. In the late 1980s the distribution of land and farm incomes remained very unequal. In 1980, 58.9 percent of farms had an annual income below US$200. The issue of unequal land distribution has not been as explosive in Panama as in many other Latin American countries. This was because of the service-oriented
