How 'parachute science' is failing the world's tropical insects
Monash University scientists have developed a global framework to tackle a major blind spot in biodiversity conservation: Insects underpin ecosystems and food production but remain largely invisible to conservation efforts across the tropics.
The world's tropical insects, essential for ecosystems, food production and biodiversity, are currently failing in global conservation efforts due to a lack of scientific knowledge and resources. Despite insects comprising 80% of insect species globally, most conservation efforts are focused on temperate regions, leaving the tropical regions - which house the majority of insect diversity - underrepresented and inadequately studied. This knowledge gap poses significant risks to effective conservation strategies.
The study led by Dr. Shawan Chowdhury from Monash University's Global Change Ecology Lab identifies four major barriers to tropical insect conservation: limited global visibility of existing research, substantial data shortfalls, inadequate research infrastructure, and insufficient conservation action. These challenges highlight the urgent need for a comprehensive framework to address the gaps in understanding and protecting these crucial species.
The researchers propose a multi-faceted approach to bridge the information gap. This includes leveraging conventional scientific research, tapping into regional and non-English literature, museum collections, local expertise, citizen science initiatives, observations shared on social media, and emerging technologies. By integrating these diverse sources of information, the framework aims to strengthen scientific capacity and ensure that conservation evidence reaches policymakers.
A case study from Bangladesh demonstrates the effectiveness of this approach. Although Bangladesh hosts a significant portion of the world's butterfly diversity, only 34 out of 111 relevant studies were published in international journals, and only three focused specifically on conservation. Social media platforms, such as Facebook, revealed a wealth of biodiversity information, with 167 out of 169 threatened butterfly species already documented online.
This highlights the potential of unconventional data sources to fill critical gaps in conventional databases, especially in regions with limited formal biodiversity resources.
The framework emphasizes the importance of converting knowledge into concrete conservation actions. In Bangladesh, for instance, while only one butterfly species was adequately represented in the country's protected area system, the integration of local knowledge, citizen science, social media, scientific monitoring, and regional expertise can provide a clearer picture of where species are most at risk and where conservation efforts should be prioritized.
Moreover, the study underscores the importance of shifting from "parachute science," where researchers from tropical countries are primarily seen as data providers rather than equal partners. Instead, the framework advocates for locally led research, investment in regional collections and infrastructure, enhanced taxonomic expertise, long-term monitoring, equitable international collaborations, and stronger connections between researchers and policy-makers.
Ultimately, the biodiversity of tropical insects is not just an insect conservation issue; it is fundamental to global ecosystems, food security, and human well-being. By adopting this comprehensive framework, the global community can transition from merely documenting the problem to implementing measurable conservation outcomes, ensuring that local scientists and communities lead the charge in protecting these vital species.
