The cattle sector plays a pivotal role in the economies of numerous Latin American and Caribbean countries. However, it also exerts a significant impact on environmental degradation, including substantial contributions to greenhouse gas emissions (accounting for 23.5 % of global livestock emissions) and deforestation (70 % attributed to livestock in South America). This article aims to investigate the complex, long-term, and short-term relationships between population growth, pastureland expansion, deforestation, and the cattle sector in 15 countries across the region, focusing on their effects on greenhouse gas emissions as well as beef and dairy production. Utilizing data from FAOSTAT spanning the period from 1990 to 2019, a cointegrated panel model was developed using the Pooled Mean Group technique, resulting in the estimation of six models. The aggregate-level results for the region reveal the presence of relatively stable long-term relationships. This implies that over time, the influence of population growth, pastureland expansion, and deforestation on greenhouse gas emissions from cattle production tends to diminish in significance. This long-term behavior may be particularly pronounced in countries with more developed cattle sectors, where efforts to mitigate the environmental impacts of cattle production, such as promoting improved forage technologies, silvo-pastoral systems, grazing management practices, and the implementation of policies, regulatory frameworks, and incentives, have gained traction. These progressive countries can serve as regional benchmarks, and the lessons they have learned hold valuable insights for the sustainable intensification of cattle production in countries with less-developed cattle sectors.
畜牧业在众多拉丁美洲和加勒比国家的经济中发挥着关键作用。然而,它也对环境退化产生重大影响,包括对温室气体排放的大量贡献(占全球牲畜排放的23.5%)以及森林砍伐(南美洲70%的森林砍伐归因于畜牧业)。本文旨在研究该地区15个国家人口增长、牧场扩张、森林砍伐与畜牧业之间复杂的长期和短期关系,重点关注它们对温室气体排放以及牛肉和奶制品生产的影响。利用联合国粮食及农业组织统计数据库(FAOSTAT)1990年至2019年期间的数据,采用聚合平均组技术开发了一个协整面板模型,从而估计出六个模型。该地区的总体结果显示存在相对稳定的长期关系。这意味着随着时间的推移,人口增长、牧场扩张和森林砍伐对养牛业温室气体排放的影响在重要性上趋于减弱。这种长期行为在养牛业较为发达的国家可能尤为明显,在这些国家,为减轻养牛业对环境的影响所做的努力,如推广改良饲料技术、林牧系统、放牧管理做法以及实施政策、监管框架和激励措施,已经取得了成效。这些先进国家可以作为区域基准,它们所吸取的经验教训对于养牛业欠发达的国家实现可持续的畜牧业集约化具有宝贵的启示。
