Forging of joined-up approach at COP29 and COP16 vital for urgent action for climate and nature

TORONTO, July 23, 2024 鈥� World leaders must take advantage of a pivotal window of opportunity for forging a much-needed joined-up approach to tackle and biodiversity loss, say scientists from 91亚色 and ZSL. Without this, work on tackling either crisis could inadvertently harm progress on the other.

Published in the Journal of Applied Ecology, a paper from international conservation charity ZSL and researchers at 91亚色, Toronto, 鈥�,鈥� conceptualizes how a joint work program between the United Nations Framework Convention on Climate Change (UNFCCC) and the United Nations Convention on Biological Diversity (CBD) could be established.

Highlighting the issues the joint program must tackle, and recommendations for successful implementation, the paper argues that such a unified political tool is critical to meet international commitments under both the Paris Agreement and the .

鈥淭he world is currently at a crossroads. World leaders have signed international treaties that commit them to take action to address these two crises, but there is currently a massive gap in the tools available to ensure this action is unified,鈥� says Professor of 91亚色鈥檚 Faculty of Liberal Arts and Professional Studies.

Boran and , a researcher at who has long been calling for united solutions to tackle climate change and biodiversity loss, are co-authors of the paper.

鈥淲e urgently need a global approach that addresses the nature and climate crises together 鈥� because they are intrinsically connected,鈥� says Pettorelli. 鈥淭he UNFCCC and CBD are incredible platforms for providing the evidence to, and guiding the way through the changes we need, but higher levels of integration between the biodiversity and climate change agendas are needed to plug implementation gaps.

鈥淭he upcoming Conference of the Parties of the UNFCCC and CBD present a clear policy window for the two conventions to introduce a formal governance structure that brings together ideas, people, organizations and processes necessary for joining the dots on how to both stabilize our climate and recover our nature.鈥�

World leaders will come together later this year for two global conventions to separately tackle climate change and biodiversity loss. In October, the CBD will meet in Columbia for the 16th United Nations Biodiversity conference (COP16). A week after its close in November, the UNFCCC will meet in Azerbaijan for the 29th United Nations Climate Change conference (COP29).

Pettorelli adds: 鈥淲ith the closely related policy agendas of the upcoming UNFCCC and CBD's COPs, negotiators have a key opportunity to take coordinated, bold and transformative action to deliver a new, more integrated and coherent approach to addressing the entwined nature and climate crises. The urgency is such that both conventions need to work together now, and take advantage of the many potential synergies we highlighted between climate change and biodiversity policies to change humanity鈥檚 course towards a sustainable future".

Government representatives at CBD COP16 will be tasked with assessing the state of implementation of the Kunming-Montreal Global Biodiversity Framework, which was adopted in 2022 and outlines a path for humanity to live in harmony with nature by 2050. The goals include halting and reversing biodiversity loss by 2030. Discussions during COP29 will be key in progress towards the landmark international treaty to limit global temperature increases to 1.5掳C above pre-industrial levels, known as the Paris Agreement.

Climate change and biodiversity loss are ; rapidly changing conditions drive the loss of species and the subsequent breakdown of ecosystems across the world 鈥� however healthy, functioning ecosystems are absolutely key to tackling climate change and mitigating its impacts.

鈥淲e need a program that fills these gaps, identifies areas where climate actions may harm to biodiversity, provides clear recommendations and develops methods to monitor progress on shared goals,鈥� says Boran. 鈥淲ithout this, we risk action to tackle one crisis creating major setbacks for the other. For example, the replacement of natural grasslands with forests may help capture and store planet-warming carbon dioxide, but it does so at a cost of the ecosystems and wildlife that previously used the land.鈥�

Properly implemented Nature-based Solutions (see note below) 鈥� natural systems that help achieve societal goals 鈥� tackle climate change and biodiversity loss simultaneously, while also bringing benefits to people. For example, the restoration of not only helps with carbon storage, but also protects the homes of species such as endangered Bengal tigers and critically endangered Philippine cockatoo, and provides food and resources for local communities.

The paper also calls for the vital need for the reallocation of resources to address imbalances in funds and support available for action to address climate change in comparison with biodiversity loss.

鈥淭here is a wider need for world leaders to ensure they鈥檙e putting nature at the heart of their decision making. Functioning ecosystems aren鈥檛 just important for addressing rapid climate change 鈥� losing them impacts every aspect of our lives, from food security to access to clean water,鈥� says Pettorelli. 鈥淲e need these to be recognized and conservation to receive the resources needed for it to be part of the solution towards tackling climate change and championing human well-being.鈥�

From restoring in the Philippines equivalent to over 1,000 football pitches to calling for the to help protect city dwellers from the worst impacts of climate change, this call is part of ZSL鈥檚 wider global work pushing for and implementing urgent action to build a better future for people and planet.

Nature Based Solutions

Nature-based Solutions are environmental approaches that address societal challenges, such as climate change, through actions to protect, sustainably manage, and restore natural and modified ecosystems, benefiting people and nature at the same time. These approaches include restoring ecosystems and protecting landscapes. Professor Pettorelli鈥檚 past work has highlighted the importance of political support for nature-based solutions in order to turn the tide on climate change and biodiversity loss, alongside specific examples of how steps such as rewilding cities and the inclusion of nature nature-friendly spaces within new housing developments are key to building a better future for all.

• Researchers say air quality monitoring networks could enable biodiversity monitoring on an unprecedented scale 
• The findings could be a gamechanger for global efforts to protect and promote biodiversity 
• They found eDNA evidence for more than 180 plants and animals in just two locations 

TORONTO, June 5, 2023 鈥� An international team of researchers has discovered that thousands of ambient air quality monitoring stations around the world are unwittingly recording more than just atmospheric pollutants and dust: they are also likely collecting biodiversity data in the form of environmental DNA (eDNA). Until now it was thought that the infrastructure for monitoring biodiversity and national and global scales does not exist.

鈥淥ne of the single biggest issues facing the planet today is the accelerating loss of biodiversity,鈥� says 91亚色 Assistant Professor Elizabeth Clare of Toronto, an expert in airborne eDNA and corresponding author of the paper published today in Current Biology. 鈥淭his could be a treasure trove of biodiversity data. What we found by analyzing filters from these monitoring stations is astonishing. In just two locations, we found eDNA evidence for more than 180 different plants and animals.鈥�&苍产蝉辫;

鈥淭he potential of this cannot be overstated. It could be an absolute gamechanger for tracking and monitoring biodiversity,鈥� says Dr of Queen Mary University of London, United Kingdom and first author of the paper. 鈥淎lmost every country has some kind of air pollution monitoring system or network, either government owned or private, and in many cases both. This could solve a global problem of how to measure biodiversity at a massive scale.鈥�&苍产蝉辫;

Until now, no one had considered that these air quality monitoring stations could be collecting and storing eDNA data on birds, bees, ticks, fungi, insects, plants and mammals across the globe as a byproduct of their regular function. But it is exactly what鈥檚 needed to monitor biodiversity at a scale that鈥檚 never been possible before. 

According to the World Wildlife Fund鈥檚 Living Planet Report, there has been a 69 per cent decline in wildlife populations since 1970. These air quality stations could be exactly what is needed to not only track biodiversity across the planet, but also to potentially tap into the decades of historic eDNA biodiversity data on filters squirrelled away for years. 

Governments, scientists and environmental agencies around the world have called for large-scale, standard methods of tracking biodiversity in real time 鈥� but it has been an impossible task 鈥� with no standardized approach and no deployed infrastructure proposed, until now.  

The discovery that these air monitoring stations could be collecting eDNA is even more surprising because they may have been quietly doing this all along.  

It wasn鈥檛 until researchers, including Clare and Littlefair, proved it鈥檚 possible to determine which species are present using eDNA sampled from air, that scientists at the UK鈥檚 (NPL), who operate the national air quality sampling grids, realized the potential of what they already had. Dr James Allerton and Dr at NPL contacted Littlefair and Clare wondering if the national air quality monitoring networks in the UK was collecting eDNA during normal operation. Together, the unlikely new collaborators have their first answer: a resounding yes. 

鈥淲e were routinely collecting particulate matter looking to measure pollutants in air but when we saw the work of Clare and Littlefair, we realized maybe we were sitting on something much more valuable,鈥� says Allerton. 

The team set up a test at an air quality station in London outside a large urban park, collecting samples for an hour, a day and a week, and compared them to eight-month-old samples from a public station in Scotland. 

At Queen Mary University of London, Littlefair handled the samples, while Clare and grad student Nina Garrett analyzed the data at 91亚色.  

鈥淲e were surprised by the diversity of life we were able to survey with one approach, almost unheard in this field of science. In these two locations, we simultaneously detected the eDNA of 34 bird and 24 mammal species, a wide variety of insects, crops, pathogenic fungus, lovely wildflowers, ornamental garden plants and grasses,鈥� says Clare of the Faculty of Science.  

鈥淲e found species of interest, such as hedgehogs, along with badgers, deer, dormice, little owls, smooth newts, songbirds and 80 different kinds of woodland trees and plants 鈥� oak, linden, ash, pine 鈥� it was all there collected on these tiny filters. It鈥檚 unbelievably exciting.鈥�&苍产蝉辫;

It represents a mechanism to measure biodiversity on land in a standardized repeatable way across entire countries continually every day, every week at thousands of locations.  

鈥淭he beauty of the idea is we are making use of something that already exists,鈥� says Brown, who operates the network at NPL. 鈥淚f networks of air samplers around the world are all collecting similar material 鈥� just as a part of their regular functioning 鈥� it鈥檚 an incredible resource.鈥�&苍产蝉辫; 

The team is now trying to preserve as many samples as possible with eDNA in mind. 鈥淲e do not yet know the true value of these samples, but as they are collected, they could provide an unprecedented view of our natural world. The scale of repeated samples could give us the elusive biodiversity time series data and the ability to measure terrestrial species dynamics in a high-resolution form never considered for biodiversity monitoring before,鈥� says Clare.  

As Littlefair says: 鈥淚t will require a global effort to collect and evaluate these samples, but this is an extraordinary opportunity to take advantage of a pre-existing, global infrastructure that has been collecting standardized eDNA data for decades and until now, we simply haven鈥檛 realized the resource existed.鈥�&苍产蝉辫;

The paper, , will be published on June 5 in the journal Current Biology.

Two independent research groups detect presence of animals by collecting DNA from air

TORONTO, DENMARK, LONDON, Jan. 6, 2022 鈥� Two new studies published today in the journal Current Biology show that environmental DNA (eDNA) collected from air can be used to detect a wide range of animal species and offers a novel, non-invasive approach to monitoring biodiversity.

The findings were made by two independent groups of researchers, one based in Denmark, the other based in the United Kingdom and Canada. Both research groups set out to test whether airborne eDNA could be used to detect terrestrial animal species. To do this, the research teams collected air samples from two European zoos, Hamerton Zoo Park, UK, and Copenhagen Zoo, Denmark.

The UK study was led by Assistant Professor Elizabeth Clare from 91亚色, Canada, then senior lecturer at Queen Mary University of London, while the Danish study was led by Associate Professor from the Globe Institute, University of Copenhagen.

Each team used a different method of filtering airborne eDNA, but both succeeded in detecting the presence of numerous animal species within and beyond the confines of the two zoos.

Bohmann鈥檚 team collected air samples using three different air sampling devices; one commercial water-based vacuum and two blower fans with filters attached 鈥� the smallest one of these two was the size of a golf ball. They collected air samples in three locations: the okapi stable, the Rainforest House and outside between the outdoor enclosures.

Clare鈥檚 team used sensitive filters attached to vacuum pumps to collect more than 70 air samples from different locations around the zoo, both inside animal sleeping areas and outside in the general zoo environment.

The results from both studies exceeded their expectations.

鈥淲hen we analyzed the collected samples, we were able to identify DNA from 25 different species of animals, such as tigers, lemurs and dingoes, 17 of which were known zoo species. We were even able to collect eDNA from animals that were hundreds of metres away from where we were testing without a significant drop in the concentration, and even from outside sealed buildings. The animals were inside, but their DNA was escaping,鈥� says Clare.

鈥淲e were astonished when we saw the results,鈥� says Bohmann. 鈥淚n just 40 samples, we detected 49 species spanning mammal, bird, amphibian, reptile and fish. In the Rainforest House we even detected the guppies in the pond, the two-toed sloth and the boa. When sampling air in just one outdoor site, we detected many of the animals with access to an outdoor enclosure in that part of the zoo, for example kea, ostrich and rhino.鈥�

Many of the detected species were kept at the zoos, but remarkably both teams also detected species from areas surrounding the zoo. The Eurasian hedgehog, endangered in the UK, was detected from outside of Hamerton Zoo, UK, while the water vole and red squirrel were detected around the Copenhagen Zoo. Both teams also picked up the presence of food items for zoo animals, such as chicken, cow, horse and fish. The wide range of detected species shows the potential that airborne eDNA could be used to detect and monitor terrestrial animal species in the wild. This would ultimately support global conservation efforts.

鈥淭he non-invasive nature of this approach makes it particularly valuable for observing vulnerable or endangered species as well as those in hard-to-reach environments, such as caves and burrows They do not have to be visible for us to know they are in the area if we can pick up traces of their DNA, literally out of thin air,鈥� says Clare. 鈥淎ir sampling could revolutionise terrestrial biomonitoring and provide new opportunities to track the composition of animal communities as well as detect invasion of non-native species.鈥�

Living organisms shed DNA into their surrounding environments as they interact with them, and in recent years, eDNA has become an important tool for species detection in a wide range of habitats. For instance, eDNA analysis of water samples is routinely used to map species in aquatic environments. However, while air surrounds everything on land, it is only now that airborne eDNA has been explored for animal monitoring.

One of the main things when demonstrating a novel eDNA sample type is to ensure that results are reliable as eDNA analyses are very sensitive and prone to contamination.

鈥淎ir is a challenging substrate to work with as air surrounds everything, which means that contamination risk is high. We wanted to ensure that the species we detected were from the zoo and not for example from the lab. To ensure that we did not have any contaminant DNA floating in the air in the lab, we sampled air from within the lab and sequenced that too,鈥� says Dr. Christina Lynggaard, who is part of the Danish team.

For these early studies, being able to replicate the work is key. The teams had no knowledge of each other鈥檚 work until the studies were completed but were thrilled by the parallel nature of the experiments. Clare and Bohmann agree that having two research teams independently demonstrate that airborne eDNA can be used to monitor a range of animal species greatly enhances the strength of their work and clearly show the potential of the technique.

鈥淲e did not think that vacuuming animal DNA from air would work,鈥� Bohmann adds, 鈥淭his was high risk, high reward science with the potential to push the boundaries of vertebrate biomonitoring. Clearly the sky is not the limit.鈥�

The use of airborne eDNA sampling in natural environments will need further research to unlock its full potential, but both research teams believe it could transform the way researchers study and monitor animal biodiversity.

Both research papers, Measuring biodiversity from DNA in the air, led by Clare, and Airborne environmental DNA for terrestrial vertebrate community monitoring, led by Lynggaard, were published today in the journal Current Biology.
