Pollinators as Indicators in Policy Affecting the Landscape and Environment

We recently participated in the Apimondia International Apicultural Congress. Now, we bring you a more detailed account of our presentation: "Using Pollinators as Indicators in Policy Affecting the Landscape and the Environment".

There is an increasing need to improve how we monitor the impact and efficiency of environmental or landscape policies. For this reason, BeeLife proposes that a Pollinator Index should be introduced as an impact indicator for policies. In need of more targeted measurements, authorities, conservation movements, researchers and citizens in general can find essential allies in pollinators. The index has the potential to help improve accountability, monitoring the effectiveness of public spending, and indicating when modifications are necessary. BeeLife insists on the importance of developing and applying a Pollinator Index in Europe.

Our planet faces significant challenges today. As a consequence, the decline in biodiversity in the last few decades has skyrocketed. The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) shared evidence of this earlier in 2019 [1]. The situation poses a challenge for nature and therefore for citizens, farmers, beekeepers, researchers and even legislators and policymakers. These last two are particularly in need of measuring the effectiveness of their laws and policies. Researchers have identified the intensification of land use, primarily by agriculture, as the main factor affecting the environment and leading to biodiversity loss, with up to 75 per cent decline in insect biomass [2]. Therefore, legislation and policies that have an impact on this are particularly influential for the future of wildlife, nature and ourselves.

Even though legislation and policy surrounding agriculture is the primary concern, it does not exclude others that also influence the landscape and the environment. In Europe, besides the Common Agricultural Policy [3], which largely shapes land use, there are also other legal acts such as the Habitat [4] or Water [5] directives. Other relevant legislation refers to Pesticide Authorisation and Use [6]. With a wide range of impact on the landscape, it is crucial to improve measuring the effects of legislation and policies.

There is an increasing need for accountability and to improve environmental conditions. It is not only in the best interest of decision-makers to get to know better the efficacy of their legislation and policies. Civil society is also demanding more transparency and better results. Convinced by the vulgarisation of scientific findings on the decline of environmental health and growing pollution, citizens are more and more preoccupied with the environment and the loss of biodiversity [7]. Evidence of this are the manifestations and the rise of green political parties that focus on environmental issues, particularly during this year's European elections [8].

Besides, several European Citizens Initiatives (ECI) have been registered in the last few years by the Commission. For example, by the initiative of citizens through several NGOs, they introduced the initiative to Ban Glyphosate and Protect People and the Environment from Toxic Pesticides in 2017 [9]. It collected over a million signatures and helped in banning the herbicide after researchers around the globe had questioned its safety [10]. Currently, other ECIs continue to advance conservation efforts. Another recently registered ECI, Save Bees and Farmers, of which BeeLife is a member, also shows the involvement of civil society [11].

The need for better accountability is clear, and there are several forms it can take. To better understand the impact of legislation and policies, authorities, researchers and other organisations have already proposed several tools. Among them, they introduced a butterfly index [12], a farm bird index and forest bird index. These indexes monitor the population of the species in question and serve as a method to measure other conditions in the environment.

Focusing on the value that pollinators have for the health of ecosystems, and the relation they have with the flora, BeeLife is now proposing also to include a Pollinator Index. The aim is for it to serve as an objective tool to monitor the real performance of public policies and their impact on the environment. As with other indexes, it would include the monitoring of populations, in this case of both managed honeybees as other wild pollinators. It can be a useful tool to monitor the real performance of different legislation and policies and their impact on the environment. It could allow the calibration of public spending towards improving public decisions that target or influence pollinators.

The Pollinator Index would include the following parameters:

  • Rate of winter and or summer honeybee colony losses. One of the primary sources of data for this is already available through the COLOSS Honeybee Research Association [13]. In collaboration with the association, along with projects that target beehive monitoring, comprehensive information can be recovered [14] [15] [16] [17] [18].

  • Wild pollinators abundance and richness. The data acquired by monitoring using traditional traps, or new technologies under development for pollinator count, would be valuable to understand the situation in the field better. The butterfly index would also be comprised here [19] [20].

  • Honeybee collected pollen pellets, analysed for their botanical origin and contaminant content. By examining pollen pellets, it is possible to associate the richness of resources and the potential toxicity from direct or indirect contact with plant protection products used in agriculture. It would also indicate possible links to land management practices in nearing areas to the apiaries [21] [22].

  • The location and period of complaints that beekeepers or naturalists present to authorities, which would require an institutional involvement of tracking and making the information available. The first-hand knowledge from fieldwork is valued and presents an indication which works in synergy with the other parameters of the Index.

  • Calculating the amount of honey or pollen produced per km2, including productivity per colony. By tracking these factors from beekeeping socioeconomics, in connection with previous parameters, the index benefits from trackings that might indicate problems with resource availability, toxicity or climatic events.

The implementation of the Pollinator Index has the potential to serve decision-makers in better establishing the goals and strategies. Thanks to a better understanding of the current challenges that pollinators face, they would be able to improve how legislation and policy shape land management. They would also be able to improve the design of tactics to achieve such objectives.

Another key feature of the Index would be enable authorities to calibrate public spending, taking into account a useful indicator of real conditions in the field. With the implementation of the Index as an impact indicator, it will be possible to modify, when necessary, the legislation and policies that target pollinators. Notably, it would enable authorities to identify the shortcomings or undesired effects and devise strategies to counter them.

Finally, the Index also comes as an answer to the pleads of civil society for transparency. It would allow citizens to understand the results of legislators and policymakers better, with a significant increase in transparency and accountability. Additionally, it would serve as a tool to verify that authorities are effectively spending public money for the preservation of public goods. With the growth of public concern for the environment and the protection of biodiversity, this Index would help civil society in ensuring their interests are seriously taken into account.

The European Commission is envisaging the creation of a Pollinator Index within the frame of the EU Pollinators Initiative. Nevertheless, it has still not seen the light, and it risks being left out of vital policies such as the CAP, which is currently under negotiation for reform. For this and its application to all other policies that impact pollinators, BeeLife requests and promotes a Pollination Index. BeeLife is at disposal to contribute to its creation, both with public institutions and researchers.

The Pollinator Index is a possible tool that promises to improve our understanding of our impact on the environment. BeeLife's motivation for supporting is to help improve conditions for pollinators in the long run. Pollinators are essential to not only the ecosystems they inhabit but also play an important role in our culture and identity. Therefore, having a tool to improve their conditions is in the best interest of nature in general and ourselves.
