This study aims to examine the impact of (i) climate change and international market price volatility on cotton production in Cameroon, (ii) climate change and international market price volatility on the prices of cotton farmers, (iii) the purchase price of cotton farmers on cotton production, (iv) cotton production on the purchase price of cotton farmers. The statistics used mainly come from the SODECOTON database, the World Bank Group Climate Change Knowledge Portal and Trading Economics. Econometric estimates made using a VAR model reveal that (i) the purchase price of seed cotton tends to significantly boost production, (ii) production does not significantly influence the purchase price of seed cotton, and (iii) the increase in the world price of cotton and significant variations in temperature are conducive to a revaluation of the purchase price of seed cotton. To improve cotton production, it would be advisable, in particular, to (i) make the purchase price of seed cotton more attractive to cotton growers and (ii) adopt effective adaptation or mitigation techniques against variations in rainfall.

这项研究旨在研究（i）气候变化和国际市场价格波动对喀麦隆棉花生产的影响；（ii）气候变化和国际市场价格波动对棉花种植者价格的影响；（iii）棉花种植者的购买价格关于棉花生产，（四）棉花生产对棉农的购买价格。使用的统计数据主要来自SODECOTON数据库，世界银行集团气候变化知识门户网站和贸易经济学。使用VAR模型进行的计量经济学估算显示：（i）籽棉的购买价格往往会大大提高产量，（ii）产量不会显着影响籽棉的购买价格，（iii）世界棉花价格的上涨和温度的显着变化有利于重新评估种棉的购买价格。为了提高棉花产量，特别建议（i）使籽棉的购买价格对棉花种植者更具吸引力，并且（ii）采用有效的适应或减缓技术以应对降雨的变化。
