Resumo
With the growing demand for food production worldwide, natural landscapes are increasingly being replaced by
agricultural areas, which directly affects biodiversity and local ecosystem services. Agroforestry systems, which
are the intentional integration of trees and shrubs into crop and animal farming systems, are a more sustainable
production approach that has been increasing in several forested areas around the globe. Here, we examine the
trends of agroforestry in the Brazilian Legal Amazon and estimate the associated value of ecosystem services
mediated by pollinators. Using data from 2006 and 2017, we detected an increase in agroforestry activity in the
Amazon, both in the number (3.27%) and in the area (23.18%) of establishments. Crop production in forested
areas increased by 45.61% in the same period, and the main products cultivated in both years were native
products from the Amazon, such as açaí , Brazil nut and babassu. Although the crop data are from forested areas,
all the five crops with the highest production value are associated with agroforestry in the Amazon. Pollination
services also increased during the same period from US$73.3 to US$156.7 million (113.76%). In 2006, the value
of pollination services corresponded to 44% of the total crop production, and it jumped to 64.43% in 2017. Bees
and beetles were the two main groups of pollinators quoted for the analysed crops. Our estimates show the
important contribution of pollinators to crop production in the Amazon forest. However, a growing loss of
Amazon forest has been observed, and this can jeopardize pollinators and have detrimental consequences on food
production in the near future. Public policies are urgently needed to encourage crop production in harmony with
natural areas, combining the protection of forests and pollinators with food production.
