Wheat production was estimated at-just over 7 million tonnes, 10 per cent hiqher than in 1981. The increase chiefly reflects a reccvery in output in Morocco, where 1981 production was sharply reduced by drouqht. Total coarse grain output was estimated at nearly 45 million tonnes, 6 million tonne.s below the 1981 figure, mainly because of damaqe to harvests caused by drouqht in several southern African and Sahelian countries. In Eastern Africa another larqe coarse qrain crop 'v'Jas forecast in Kenya. Somalia and the United Republic of Tanzania harvested better crops than in 1981, but crops in Ethiopia and Rwanda were estir.1ated to be 1 ewer. 2. Food production 6. Accordinq to data provided by FAO, focu production in developing Africa rose by 2.7 per cent in 1981 compared to 4.0 
analysis: The text primarily discusses agricultural production and its growth rates in different regions of Africa, which suggests a strong connection to the agricultural sector. Additionally, it mentions food production, wheat and coarse grain output, and droughs that affect harvests, further supporting the idea that the text is related to agriculture. The mention of developing countries and ECA secretariat also indicates that the text may be related to economic development.
