This paper analyzes household decisions to adopt varying degrees of agroforestry systems. A survey of farming practices and household characteristics were collected from a random sample of 435 households in Tabora, Tanzania (n = 386). Using multinomial logistic methods, we estimated models explaining adoption behavior with respect to multiple agroforestry systems, as well as partial adoption of agroforestry packages. We explored how household health and access to health services, credit access and mobile banking use, land tenure and firewood access, and extension services are associated with agroforestry adoption. Results indicated the importance of access to credit for tree planting, which is significantly associated to the adoption of the fertilizer tree Gliricidia sepium, and the combination of Gliricidia sepium and planted woodlots. We also found that acres farmed, education, and extension services are significantly associated to the adoption of the full agroforestry package (adoption of pigeonpea and cassava intercropping). Different household characteristics were associated with partial adoption of the intercropping package (pigeonpea or cassava with other food crops), including land tenure, health clinic access, and whether firewood is collected from the commons. Implications of these findings could be used by agencies promoting agroforestry systems to better understand what factors contribute to the likelihood of agroforestry adoption.

本文分析了采用不同程度的农林业系统的家庭决策。从坦桑尼亚塔博拉（n = 386）的435户家庭中随机抽取了一份有关农作方法和家庭特征的调查。使用多项逻辑方法，我们估算了解释多种农林业系统采用行为以及部分采用农林业组合的模型。我们探讨了家庭健康和获得卫生服务，信贷和手机银行使用，土地保有权和薪柴使用以及推广服务与农林业的采用之间的关系。结果表明获得信贷对植树的重要性，这与采用化肥树Gliricidia sepium以及虎杖和人工林。我们还发现，种植农田，提供教育和推广服务与采用完整的农林业配套（采用木豆和木薯间作）密切相关。不同的家庭特征与部分套种套种（木豆或木薯以及其他粮食作物）的采用有关，包括土地使用权，卫生诊所的通道以及是否从公地收集柴火。促进农林业系统的机构可以利用这些发现的含义，以更好地了解哪些因素促成了农林业采用的可能性。
