The new policy has not been a success. The share of agriculture in GDP fell from about 60% at the beginning of the 1960s to 36% 20 years later. The food self-sufficiency target has not been reached. However, as the population outgrows food production, resort has been made to food imports. Finally, the production of export crops has been very mixed, with negative trends for some of the most important crops. The agricultural sector continues to provide most of the employment in the country largely due to the failure of the non-agricultural sectors to develop sufficiently rapidly.
