在哥伦比亚，三分之一的土地用于养牛，这是森林砍伐、土地退化、生物多样性丧失和温室气体排放的主要原因之一。为了减轻养牛业对环境的影响，广泛推广农林业做法，但结果好坏参半。尽管在过去 20 年期间进行了研究和推广工作，农林业系统仍然涉及利益相关者之间复杂的知识过程，需要解决。为了了解养牛户采用农林业做法的行为驱动因素，我们对不同的社会、经济和生产信息应用双障碍回归，以捕获采用的决定和采用的强度，作为此类做法的联合决策。为此，我们使用了一项调查数据（作为国际项目的一部分实施），该调查对哥伦比亚五个农业生态区的 1605 名养牛户进行了调查。我们的因变量是通过采用四种农林业实践来定义的：分散的树木、用于饲料生产的树木和灌木、林业种植园以及原生森林的管理。农林业实践的采用决定受到信贷的获取和使用、地点和实施的畜牧系统的影响。畜群规模和参与涉及植树的开发项目对农林业实践的采用和强度产生积极影响，而与泉水存在相关的变量往往会提高采用的强度。这些技术在已经采用和潜在采用的农民中的传播可能会得到加强，社会资本和网络可以在传播农林业作为可持续实践方面发挥关键作用。
In Colombia, one-third of the land is devoted to cattle farming, which is one of the main drivers of deforestation, land degradation, loss of biodiversity, and emissions of greenhouses gases. To mitigate the environmental impacts of cattle farming, agroforestry practices have been extensively promoted with mixed results. Despite research and extension efforts over the last 20-year period, agroforestry systems still involve a complex knowledge process among stakeholders that needs to be addressed. To understand the drivers of cattle farmers' behavior with regard to adopting agroforestry practices, we apply a double hurdle regression for different social, economic and productive information to capture the decision to adopt and the intensity of the adoption as a joint decision of such practices. For this purpose, we use data from a survey (implemented as part of an international project) administered to 1605 cattle farmers located in five agro-ecological regions in Colombia. Our dependent variables are defined by the adoption of four agroforestry practices: scattered trees, trees and shrubs for forage production, forestry plantations, and management of native forest. The adoption decision of agroforestry practices was influenced by the access and use of credit, location, and the implemented livestock system. Herd size and participation in development projects that involved tree planting had a positive influence on the adoption and intensity of agroforestry practices, while the variable associated with presence of water springs tended to boost the intensity of adoption. The diffusion of these technologies might be increased among farmers who have adopted and who are potential adopters, and social capital and networking can play a crucial role in spreading agroforestry as sustainable practice.
