The historical development of capitalism created what Karl Marx called a rift in the social metabolism with nature, whereby soil nutrients were systematically siphoned into cities where they were discarded as waste and thus did not return to the land. An alternative mode of food production known as agroecology was developed by different scientists and activists partly to transcend this contradiction. Drawing on data from the United Nations and the World Bank, this work analyzes whether agroecology has contributed to mitigate the metabolic rift in agriculture in Cuba, the country where this approach to food production, adopted after the dissolution of the Soviet Union in 1991, is more widely developed. By means of a panel model, both an internal comparison through time within Cuba and a cross-national comparison of Cuba with the rest of Latin America and the Caribbean (LAC), were developed to determine whether the post-Soviet transition to agroecology in Cuba successfully decoupled industrial agricultural practices from productivity in comparison to other countries in LAC. Decoupling is understood as the removal of the positive correlation between fertilizer use and yield. Synthetic fertilizer use is utilized as an indicator of industrialized agriculture, and productivity of maize and beans as a proxy measure of soil improvement. The model shows a reversal of the fertilizer use and productivity positive correlation in Cuba, where crop productivity has increased while the use of inputs has diminished, which suggests that agroecology has indeed mitigated the metabolic rift produced by industrialized agriculture.

资本主义的历史发展创造了卡尔·马克思所谓的与自然的社会新陈代谢的裂痕，土壤养分被有系统地虹吸到城市中，在那里它们被当作废物丢弃，因此没有返回土地。不同科学家和激进主义者开发了另一种称为农业生态的粮食生产方式，以部分克服这一矛盾。这项工作利用联合国和世界银行的数据，分析了农业生态学是否有助于减轻古巴农业的新陈代谢裂痕。古巴是1991年苏联解体后采用的这种粮食生产方式。更广泛地发展。通过面板模型，既进行了古巴内部时间的内部比较，又进行了古巴与拉丁美洲和加勒比海其他地区（LAC）的跨国比较，以确定苏联在苏维埃向农业生态过渡后是否成功地将工业农业实践与生产力脱钩了与拉丁美洲和加勒比地区的其他国家相比。解耦被理解为消除了肥料使用与产量之间的正相关关系。合成肥料的使用被用作工业化农业的指标，玉米和豆类的生产力被用作土壤改良的替代指标。该模型显示了古巴肥料使用与生产力的正相关关系发生了逆转，古巴的生产力提高了，投入的使用却减少了，
