与作为生物多样性避难所的环境和保护价值相比，人们对遮荫咖啡系统的社会和经济价值知之甚少。农林系统可作为多种用途的非咖啡产品的来源。这项研究的重点是遮荫树在小农咖啡农场的作用，检查来自遮荫咖啡系统的木材产品。对秘鲁185名种植者和危地马拉153名种植者的调查提供的数据表明，所有非咖啡产品的消费和销售占农林系统实现的总价值的五分之一到三分之一。薪材和建筑材料占这一价值的大部分。各国之间的差异可以追溯到农业集约化----咖啡农林业系统“技术化”的程度（即，管理时减少遮荫树覆盖和多样性、高产品种、农用化学品投入等）- 以及对木材资源的相对需求和农民利用天然林系统的机会。
Compared to the environmental and conservation value as refuges for biodiversity, less is known about the social and economic value of shaded coffee systems. The agroforestry system can serve as a source of non-coffee products for diverse purposes. This study focuses on the role of shade trees in smallholder coffee farms, examining the wood products derived from the shaded coffee system. Data presented from surveys with 185 growers in Peru and 153 growers in Guatemala show that the consumption and sale of all non-coffee products account for a fifth to a third of the total value realized from the agroforestry system. Fuelwood and construction materials account for much of this value. Differences seen between countries can be traced to agricultural intensification – the degree to which the coffee agroforestry system is “technified” (i.e., managed with a reduced shade tree cover and diversity, high-yielding cultivars, agrochemical inputs, etc.) – as well as the relative demand for wood resources and farmers’ access to natural forest systems.
