加纳的可可生产基本上依靠雨水，这使其容易受到气候变化和多变性的影响。本文是一项正在进行的研究的一部分，该研究正在调查加纳气候条件的变化如何影响可可业的生产水平。这项研究基本上使用了加纳可可营销公司和加纳气象局在夸梅恩克鲁玛科技大学、库马西和库马西机场的气象站1970年至2010年的二级数据。研究结果显示，1970年至1984年间，研究地区的可可产量下降了约100，000公吨，而降雨量则呈增加趋势。尽管如此，总降雨量与降雨开始时间和可可产量之间的直接关系无法确定。然而，研究发现，降雨开始和年降雨总量的气候变异对可可产量有非常显著的影响（p值0.01）。因此，该研究得出结论，气候变化和多变性对加纳的可可业产生了影响，需要采取有效的缓解措施。关键词：可可生产，气候变化和变异
Cocoa production in Ghana is basically rain fed and this makes it vulnerable to climate change and variability. This paper is part of an on-going research, which is investigating how changes in the climatic conditions in Ghana are affecting production levels of the cocoa industry. The study uses basically secondary data from the Ghana Cocoa Marketing Company and the Ghana Meteorological Service Weather stations at the Kwame Nkrumah University of Science and Technology, Kumasi and the Kumasi Airport between 1970 and 2010. Findings from the study reveal a decline in cocoa production of about 100,000 metric tonnes between 1970 and 1984 in the study region and increasing trend of rainfall totals. Notwithstanding, a direct correlation between rainfall totals and rainfall onsets; and cocoa yields could not be established. However, the study found a highly significant effect of climate variability in rainfall onset and annual rainfall totals on cocoa yield (p-value 0.01). The study thus concludes that climatic change and variability have influence on Ghana’s cocoa sector which calls for effective mitigation measures. Keywords: cocoa production, climate change and variability
