文章历史接收：2020年7月3日接受日期：2020年7月28日在线发布日期：2020年7月31日旱地占全球土地的40%以上，特别容易受到气候变化的影响。在其中许多旱地，畜牧活动是土地使用的主要形式。在巴西，塞拉多和卡廷加这两个主要的旱地生物群落在该国的畜牧业活动中发挥着关键作用。这些活动虽然在经济上很重要，但也造成大量温室气体的排放。缓解气候变化影响的一个建议战略是采用森林牧场系统，即在同一块土地上同时将树木、牧场和动物联合收割机结合起来。巴西旱地的农民有着实行卫生和植物检疫措施的悠久历史。森林养护的做法与气候变化和经济有关，但不一定与生物多样性丧失和经济不平等问题有关。过去的农村农业发展项目，如与“绿色革命”有关的项目，缺乏跨学科性，导致经济不平等加剧和生物多样性丧失。目前的工作，侧重于巴西旱地，审查这些问题，以证明需要考虑到土壤质量，树木密度，生物多样性丰富，农民的看法等多个变量的跨学科项目。
Article history Received: 3 July 2020 Accepted: 28 July 2020 Published Online: 31 July 2020 Drylands constitute more than 40% of global land and are particularly vulnerable to the impacts of climate change. In many of these drylands, livestock activities are a major form of land-use. In Brazil, the two major dryland biomes, Cerrado and Caatinga, play a key role in the country’s livestock activities. While important economically, these activities also contribute to the emission of high amounts of greenhouse gases. One suggested strategy for mitigating the impacts of climate change is the adoption of silvopastoral systems (SPS) which combine trees, pasture, and animals simultaneously on the same unit of land. Farmers in the drylands of Brazil have a long history of practicing SPS. The practice of silvopasture is relevant to both climate change and the economy, but not necessarily to the issues of biodiversity loss and economic inequality. The lack of interdisciplinarity in rural agricultural development projects in the past, such as those related to the “Green Revolution”, resulted in the aggravation of economic inequalities and biodiversity loss. The present work, focusing on the Brazilian Drylands, reviews these issues to justify the need for interdisciplinary projects considering multiple variables like soil quality, tree density, biodiversity richness, and farmers’ perception.
