Q: One of the most successful agricultural production region is located where?, Context: Tea, coffee, sisal, pyrethrum, corn, and wheat are grown in the fertile highlands, one of the most successful agricultural production regions in Africa. Livestock predominates in the semi-arid savanna to the north and east. Coconuts, pineapples, cashew nuts, cotton, sugarcane, sisal, and corn are grown in the lower-lying areas. Unfortunately, the country has not attained the level of investment and efficiency in agriculture that can guarantee food security and coupled with resulting poverty (53% of the population lives below the poverty line), a significant portion of the population regularly starves and is heavily dependent on food aid. Poor roads, an inadequate railway network, under-used water transport and expensive air transport have isolated mostly arid and semi-arid areas and farmers in other regions often leave food to rot in the fields because they cannot access markets. This was last seen in August and September 2011 prompting the Kenyans for Kenya initiative by the Red Cross.
