“Guinea has a tropical climate with two alternating seasons, a November–March dry season and an April–October rainy season. In general, rainfall increases from north to south. Average annual rainfall is 1,988 mm. Rice is the staple crop, and other important food crops are corn, fonio groundnuts, and cassava. Most of the population is rural, and the agricultural sector is the major employer. The population is expected to double by 2040–2050. In addition to increasing demand for social services (health, education, water supply, electricity, and related infrastructure), growth will put pressure on agricultural land, which will result in a further reduction in the fallow period, decreasing yields, unless compensated for in some other way.”
