动物传粉者为人类的粮食生产和安全作出了贡献，从而确保了人类福祉的重要组成部分。这些传粉剂最近在欧洲和北美的下降引起了人们对潜在的全球传粉者危机的担忧。为了优先保护传粉者，我们评估了巴西的粮食生产对动物传粉者的依赖程度，巴西是世界农业领先者之一，我们通过比较依赖传粉者和不依赖传粉者的主要粮食作物的种植面积、产量和产值来评估粮食生产。此外，我们根据每种作物对传粉者的依赖程度以及粮食产量下降对巴西国内生产总值和巴西粮食安全的影响来评估授粉的生态系统服务。在巴西的53种主要粮食作物中，共有68%的作物在某种程度上依赖动物授粉。传粉者不依赖的作物产生更多的食物，主要是因为甘蔗产量高，但传粉者依赖的作物的种植面积和货币价值更高(占总耕种面积的59%和货币价值的68%)。29种主要粮食作物失去授粉服务将减产1655-5100万吨，相当于486-145.6亿美元/年，农业对巴西国内生产总值的贡献减少6.46%-19.36%。这些影响将主要由家庭农民吸收，他们占巴西农业劳动力的74.4%。巴西传粉者危机的主要影响将由较贫穷和更多的农村阶层感受到，因为他们的收入较低，直接或完全依赖这一生态系统服务。
Animal pollinators contribute to human food production and security thereby ensuring an important component of human well-being. The recent decline of these agents in Europe and North America has aroused the concern of a potential global pollinator crisis. In order to prioritize efforts for pollinator conservation, we evaluated the extent to which food production depends on animal pollinators in Brazil—one of the world’s agriculture leaders—by comparing cultivated area, produced volume and yield value of major food crops that are pollinator dependent with those that are pollinator non-dependent. In addition, we valued the ecosystem service of pollination based on the degree of pollinator dependence of each crop and the consequence of a decline in food production to the Brazilian Gross Domestic Product and Brazilian food security. A total of 68% of the 53 major food crops in Brazil depend to some degree on animals for pollination. Pollinator non-dependent crops produce a greater volume of food, mainly because of the high production of sugarcane, but the cultivated area and monetary value of pollinator dependent crops are higher (59% of total cultivated area and 68% of monetary value). The loss of pollination services for 29 of the major food crops would reduce production by 16.55–51 million tons, which would amount to 4.86–14.56 billion dollars/year, and reduce the agricultural contribution to the Brazilian GDP by 6.46%– 19.36%. These impacts would be largely absorbed by family farmers, which represent 74.4% of the agricultural labor force in Brazil. The main effects of a pollinator crisis in Brazil would be felt by the poorer and more rural classes due to their lower income and direct or exclusive dependence on this ecosystem service.
