A review of the effects of agricultural intensification and the use of pesticides on honey bees and their products and possible palliatives

Abstract

There is considerable scientific evidence revealing a decrease in pollinating insects in different ecosystems around the world. In this context, agricultural intensification and the use of phytosanitary products are likely the main causes. This problem is common to many pollinators but of particular ecosystemic, economic and bromatological significance for honey bees (Apis mellifera) since their presence in these landscapes is mainly due to the proximity of apiaries for human food production and because they are the most important biotic pollinators of agricultural crops. In this review, we present a synthesis of the results of several years of research on this topic, as well as potential solutions referenced in the bibliography that might help alleviate the effects of contamination on honey bees and their products. Additionally, we expose the possible limits of the real implementation of such solutions and conclude on the need to implement land-use planning strategies for agricultural systems. Without mitigating actions in the short term, the sustainability of agricultural ecosystems as bee-friendly habitats and the production of foods suitable for human consumption are uncertain.
