The Movement of Pollen:

Pollinators, People, and the Planet

In this perspective we introduce the human-crop-bee relationship through the movement of pollen. A broad overview of pollinators and pollination is provided, with an emphasis on bees. We describe, in part, the relationship between bees and people and the three-way reciprocity that exists in the human-bee-crop connection. We distinguish between conservation of wild bee populations and the management of honeybees by beekeepers. Even though honey bees have become a symbol for conservation and environmentalism more broadly, they are not found on any species-at-risk list. Instead, it is native, wild bee species that are endangered or of concern in Canada and beyond. The pollination services of honey bees in their constructed, mobile hives, have long been thought to be critical for conventional agriculture that relies on large swathes of monocultures requiring biotic pollination. However, increasingly, even in commercial systems, the important role of wild bumble bees, solitary bees and stingless bees in crop pollination is being recognized, in some cases as more important than honey bees. In plants, genetic material is passed through pollen and a diversity of plants is reflected in the diversity of animals that pollinate them. And yet, the very food systems that need bees may be putting them in peril in a variety of ways. True reciprocity requires adjustment but provides long term sustainability to the plant systems that humans and bees alike depend on for food.

A Socio-Ecology of Pollination:

A Case Study

Our case contribution examines a socio-ecology of pollination. We explore the themes of meaning and movement in several ways. We consider how food moves/migrates and how a parallel pollen movement via pollinators occurs. For example, cucurbita crops (pumpkin and squash) are human-domesticated crops, making them incapable of thriving in the wild. These crops were moved across North America via human seed-sharing and trade routes from the crop’s centre of origin in Meso America. The spread of the crop facilitated the spread of one of its most important pollinators, the wild hoary squash bee (Eucera (Peponapis) pruinosa) that co-evolved with the crop’s wild ancestors to become a cucurbita pollen specialist. The bee’s spread into regions, like Ontario, where there are no wild cucurbita, creates an important reciprocity where the bees, the crop, and humans depend on each other for success. These movements (movement of seeds, movement of pollen) help us to understand that food is more than what we put in our mouths, and that pollination is a natural process that links us to nature and to crops in the most intimate of ways via the foods (pollen or fruit) provided by the crop that is literally taken into the body of both bees and humans.

Chapter Title: How conserving insect biodiversity in agroecosystems underpins sustainable diets

Abstract: Biodiversity encompasses the variety of life, measured at the genetic, species, or ecosystem level. Insects create the foundation for all ecosystems and represent a large component of the biodiversity found within agroecosystems. Though insects interfere with the capacity of human societies to produce food by consuming crops and spreading plant diseases, insects also play numerous important roles in supporting production of food for sustainable diets. In this chapter, we begin with a high-level review of the important contributions of insects to biodiversity in agroecosystems. Then, using a series of short case-studies we share how insect biodiversity supports sustainable diets through influencing the social, economic, and environmental components of sustainability. In the first, we explore the human-pollinator nexus through our understanding, interaction, and management of bees. In the second, we share how insect biodiversity supports the economic sustainability of food production through biological control of pests. An exceptionally diverse guild of insects (parasitic wasps and flies) supports this important function. We share several examples explaining how these ‘natural enemies’ help farmers avoid economic losses to pests. In the third, spanning the global north and south, we share how dung beetles underpin the environmental sustainability of diets through building soil carbon, reducing greenhouse gas emissions, and suppressing pathogens and disease. We conclude by discussing some of the threats to insect biodiversity in agroecosystems, and overview the value that principles of organic production and contemporary agri-environmental policy have placed on conserving insect biodiversity now and into the future.
