Ghana is the second largest producer of cocoa. The country produces a variety of crops in various climatic zones which range from dry savanna to wet forest and which run in eastwest bands across the country. However, despite its importance, sectoral growth has lagged behind other sectors of the economy and has been unpredictable, as most farming is reliant upon rainwater. The removal of subsidies on fertilizers and other agricultural inputs has also had an effect on several crops. Although most of the year-to-year trends are attributable to weather patterns, the longer term improvement in performance can be attributed to public policy changes. As part of the broader macroeconomic reforms the government has removed food price controls , raised cocoa prices paid to producers, and boosted extension services, which help increase farmer productivity. The lack of government financial support again put subsistence producers at a disadvantage.
