GDP qrowth in the majority of the countries of this qroup was either weak or negative; exceptions, were countries like Ethiopia, with 20 E/ECA/CM.9/5 lower but still relatively high growth in agriculture, and Upper Volta which benefited from a bu.mper crop after several years of drought. Per capita income group of $200 to under $300 recorded no gains in-average per capita income growth, and country perfor­ wance ~as mixed: Countries like Cape Verde, Eaypt and Mauritius registered very high growth while others like Angola, Liberia, Morocco and Seneqal were in qreat difficulties. Less satisfac­ tory however \vas the performance of the qroup of countries with per capita income of$ 300 to under$ 400 where with the exception oi--'I'unisia all have either slipped or shewn medium growth. Per capita fnc·bme qroup of $100 to under$ 200, as always, continued Eo-snew,strong growth, this year mostly because of the exception­ al high growth in the southern African countries like Botswana and Zimbabwe. 11. Growth in North and viest Africa continued to be greatly in­ fluenced by developments in their agricultural a nt1 mining sec­ tors. Thus the fall in their respective GDP qrowth from 5.1 per cent and 1.1 per cent in 1980 to a negative of 0.6 per cent for each is a reflection of this fact. In North Africa mining production declined in 1980 but the doubling of oil prices in 1979-1980 more than making for the output 1 oss which reached 11 .1 per cent. In 1981 however, the saturation of the world oil market and the lower demand at prevaili£1g prices forced countries like the Libyan Arab Jamahiriya to reduce production drastically. In effect there was a drop of about 20 per cent in mining sec• tor's output in 1981 and the decline in 1982 is expected to be
