A growing population with increasing consumption of milk and dairy require more agricultural output in the coming years, which potentially competes with forests and other natural habitats. This issue is particularly salient in the tropics, where deforestation has traditionally generated cattle pastures and other commodity crops such as corn and soy. The purpose of this article is to review the concepts and discussion associated with reconciling food production and conservation, and in particular with regards to cattle production, including the concepts of land-sparing and land-sharing. We then present these concepts in the specific context of Colombia, where there are efforts to increase both cattle production and protect tropical forests, in order to discuss the potential for landscape planning for sustainable cattle production. We outline a national planning approach, which includes disaggregating the diverse cattle sector and production types, identifying biophysical, and economic opportunities and barriers for sustainable intensification in cattle ranching, and analyzing areas suitable for habitat restoration and conservation, in order to plan for both land-sparing and land-sharing strategies. This approach can be used in other contexts across the world where there is a need to incorporate cattle production into national goals for carbon sequestration and habitat restoration and conservation.
随着人口增长以及牛奶和乳制品消费量的增加，未来几年需要更多的农业产出，这可能会与森林和其他自然栖息地形成竞争。这个问题在热带地区尤为突出，在那里，森林砍伐传统上用于开辟牧场以及种植玉米和大豆等其他经济作物。本文的目的是回顾与协调粮食生产和保护相关的概念及讨论，特别是关于养牛生产，包括土地节约和土地共享的概念。然后，我们将这些概念置于哥伦比亚的具体背景下进行阐述，该国正在努力增加养牛生产并保护热带森林，以便探讨可持续养牛生产的景观规划潜力。我们概述了一种国家规划方法，其中包括对多样化的养牛业和生产类型进行分类，确定肉牛养殖可持续集约化的生物物理和经济机遇与障碍，分析适合栖息地恢复和保护的区域，从而规划土地节约和土地共享战略。这种方法可用于世界上其他需要将养牛生产纳入国家碳固存以及栖息地恢复和保护目标的地区。
