Are you interested in why bees matter for cities?

---

Our summary today works with the article titled Why bees are critical for achieving sustainable development? from 2021 by Vidushi Patel, Natasha Pauli, Eloise Biggs, Liz Barbour, and Bryan Boruff, published in Ambio – A Journal of Environment and Society. This is a great preparation to our next interview with Simon Burt in episode 220 talking about bees and their connection to cities. Since we are investigating the future of cities, I thought it would be interesting to see how bees contribute to sustainable development. This article investigates the threats of bee population reductions and the broader importance of bees to sustainable development beyond their role in promoting food security and biodiversity.

Welcome to today’s What is The Future For Cities podcast and its Research episode; my name is Fanni, and today I will introduce a research paper by summarising it. The episode really is just a short summary of the original paper, and, in case it is interesting enough, I would encourage everyone to check out the whole paper. Stay tuned until because I will give you the 3 most important things and some questions which would be interesting to discuss.

In our quest for sustainable development, the decline of global bee populations emerges as a profound threat to the intricate dance between pollination, the planet, and people. This decline not only endangers the essential pollination benefits for food production and biodiversity but also points to a broader, often underappreciated spectrum of contributions that bees make towards sustainable human livelihoods and ecosystem health. Recognizing bees’ role transcends the act of pollination, drawing into focus their potential in supporting 15 of the United Nations’ Sustainable Development Goals (SDGs), addressing no less than 30 specific targets.

Bees play an indispensable role in the ecology of pollination, underpinning the survival and propagation of a myriad of flowering plant species, which are crucial for food production and biodiversity on our planet. With around 20,000 described species, bees’ ecological contributions extend far beyond their primary role in pollination, touching every aspect of the web of life that sustains the Earth’s diverse ecosystems. Their evolution alongside flowering plants has equipped them with unique adaptations, such as their ability to carry significant amounts of pollen, reliance on floral resources, and, in some species, sophisticated social structures, all of which enhance their pollination efficiency. While bees are the most dominant group of pollinators globally, only a small number are actively managed by humans for crop pollination. Yet, these managed bees are critical, contributing significantly to the pollination of many of the world’s crucial crops, thereby playing a vital economic role in global agriculture and food security.

The relationship between bees and humans is deeply rooted in history and culture, stretching back to ancient practices of honey hunting and beekeeping. This relationship is evidenced in archaeological findings, religious texts, and cultural traditions around the world, showcasing bees’ significance beyond their ecological roles. Bees have been revered in various cultures for their virtues of industriousness and community living, and have been integral to human livelihoods through the ages, providing honey, beeswax, and other products. However, this millennia-old symbiosis faces modern threats from habitat destruction, pesticide use, diseases, and climate change, leading to worrying declines in bee populations. These declines not only threaten the ecological benefits bees provide through pollination but also the cultural, economic, and social practices that have evolved alongside bees. This situation underscores the urgent need for concerted conservation efforts aimed at protecting and restoring bee populations to ensure the continuation of the vital services they provide to both the planet and its people.

The critical role of bees in sustainable development is far-reaching, encompassing not only their contributions to food security through the pollination of crops but also their broader impacts on ecological, economic, and social systems. Bees’ pollination services are fundamental to the production of a vast array of fruits, vegetables, and nuts, directly influencing food security and nutritional diversity. This is particularly vital in a world grappling with the challenges of feeding a growing population under the shadow of climate change. Beyond improving crop yields, bees also enhance the quality of food, contributing to the nutritional value and shelf life of produce. Their work supports the agricultural sector, not just by bolstering food production but also by sustaining the biodiversity of crops, which is crucial for resilient agricultural systems and ecosystems.

Moreover, bees play a significant role in biofuel production, urban ecology, and the preservation of genetic diversity within agricultural systems. By pollinating biofuel crops, bees contribute to the sustainability of energy sources, linking their ecological roles to broader energy and climate goals. In urban environments, bees support the health of green spaces, enhancing urban biodiversity and contributing to the well-being of urban communities. Their presence in cities can bolster urban agriculture initiatives, providing essential pollination services that can lead to more green spaces and improved urban air quality. Additionally, the genetic diversity promoted by bee pollination is vital for the adaptability and resilience of agricultural ecosystems, ensuring that crops can withstand pests, diseases, and environmental changes.

The decline in bee populations, however, poses a significant threat to these benefits, underscoring the urgency of integrating bee conservation into sustainable development strategies. The loss of bees could lead to reduced crop yields and quality, impacting food security and economic stability, particularly for communities reliant on agriculture. Therefore, protecting bee populations is not only an ecological imperative but also a critical component of sustainable development efforts aimed at ensuring food security, promoting sustainable agriculture, and maintaining biodiversity. It highlights the need for policies and practices that support bee health and habitat, including reducing pesticide use, promoting landscape diversity, and fostering practices that support both wild and managed bee populations.

The journey towards sustainable bee systems is fraught with challenges but illuminated by the potential for positive change. Addressing bee decline requires a concerted effort across research, policy-making, and public awareness. It calls for a holistic view that embraces both wild and managed bee populations, recognizing the integral role bees play in supporting not just pollination but also the wider goals of sustainable development. This narrative advocates for natural resource management practices that sustain bee health, ensuring that these critical pollinators can continue to support the balance of ecosystems, human well-being, and the resilience of our planet for generations to come.

Finally, as the most important things, I would like to highlight 3 aspects:

1. Bees play a crucial role in pollination, directly impacting food security, biodiversity, and sustainable agriculture by supporting the pollination of a wide array of crops and wild plants.
2. The decline in bee populations due to habitat loss, pesticides, and climate change poses a significant threat to their ecological benefits, highlighting the urgent need for conservation efforts to protect these vital pollinators.
3. Bees contribute to achieving 15 of the 17 United Nations’ Sustainable Development Goals (SDGs), underscoring their broad importance beyond pollination to include economic, environmental, and social dimensions of sustainable development.

Additionally, it would be great to talk about the following questions:

1. How can modern urban planning incorporate green spaces to support bee populations and biodiversity in cities?
2. How can the intersection of traditional beekeeping knowledge and scientific research forge new paths for bee conservation?
3. Considering the critical role of bees in our food system, what steps can individuals and communities take to promote bee-friendly environments?
