Global policy-makers must take a more ambitious approach to reversing biodiversity loss

University of Kent

A group of leading conservationists, including Dr Joseph W. Bull at the University of Kent, is urging governments across the globe to adopt a new approach to address the impact of economic development on our natural world.

In a new paper, published by Nature Ecology and Evolution, they call for a focus on 'net positive outcomes for nature'. The approach rejects the idea that loss of biodiversity is an inevitable consequence of economic development and instead calls for more ambitious, proactive measures to ensure greater benefits to our natural environment are achieved in concert with development activities.

This new net positive approach is underpinned by the concept of a Conservation Hierarchy, which provides a framework for structuring biodiversity conservation actions based on how they contribute to our shared overall vision for our natural world. The Hierarchy would allow for the proactive, strategic consideration of conservation actions - shifting our focus away from more reactive piecemeal actions to protect species or habitats. It seeks to extend the focus of conservation efforts beyond increasing the number of designated protected areas, to also focus on reducing the impact of development as it happens, retaining and restoring habitats proactively, and enhancing the prospects for nature everywhere.

The framework would allow the whole range of conservation efforts to be tracked at a global level, whether they are implemented by national governments, indigenous groups, businesses or private individuals. This then provides for more consistent, comprehensive and informative evaluation of the progress we are collectively making towards restoring nature.

The Conservation Hierarchy is more ambitious than current policy commitments, which typically relate only to location-specific impacts, particular species trends or certain sectors of the economy. It outlines how the global community can move to a position in which economic development activities would be integrated with, rather than in opposition to, positive biodiversity outcomes.

The conservationists are calling for a shift in the language and approach to global conservation policy discussions in advance of next year's UN Convention on Biological Diversity, which will be held in China and will set the strategic plan for biodiversity for the next decade and on to 2050. They argue that nations adopting a headline target of net positive outcomes for biodiversity would have major implications for the way that conservation is delivered and encourage greater engagement with nature conservation around the world.

The research was led by Dr Joseph W. Bull, Senior Lecturer in Conservation Science at Kent's Durrell Institute of Conservation and Ecology. He worked with professors EJ Milner-Gulland (University of Oxford) and James Watson (University of Queensland and Wildlife Conservation Society), as well as additional co-authors to produce the report, including collaborators from several major international conservation organisations, such as the World Wildlife Fund.

Dr Bull said: 'The loss of native species and habitats is a pattern that is being repeated in gardens, farmlands, wildlands, rivers and oceans across the planet. The current focus on protecting what nature remains is not nearly enough. We must find ways to not only halt, but also to reverse, biodiversity loss. We should be going above and beyond our current actions to seek conservation gains wherever possible.'

Professor Milner-Gulland said: 'The world must take the leap from a focus on actions that prevent biodiversity loss, and instead adopt a proactive approach to restoring nature. The Conservation Hierarchy provides the underpinning for the truly ambitious action which the public are demanding, to achieve a sustainable, wild and socially-just world.'

Professor Watson said: 'It is obvious that nature is running out of time, and nations have one last chance to get a bold target in place to halt the declines and extinctions that are now commonplace across the world. Only with a bold headline goal that calls for a net gain for nature, will it be possible for governments and industry to work hand in hand to avert the biodiversity crisis.'

Notes to Editors

The University of Kent is a leading UK university producing world-class research, rated internationally excellent and leading the way in many fields of study. Our 20,000 students are based at campuses and centres in Canterbury, Medway, Athens, Brussels, Paris, Rome and Tonbridge.

With 97% of our research judged to be of international quality in the most recent Research Assessment Framework (REF2014), our students study with some of the most influential thinkers in the world. Universities UK recently named research from the University as one of the UK's 100 Best Breakthroughs of the last century for its significant impact on people's everyday lives.

We are renowned for our inspirational teaching. Awarded a gold rating, the highest, in the UK Government's Teaching Excellence Framework (TEF), we were presented with the Outstanding Support for Students award at the 2018 Times Higher Education (THE) Awards for the second year running.

Our graduates are equipped for a successful future allowing them to compete effectively in the global job market. More than 95% of graduates find a job or study opportunity within six months.

Known as the 'UK's European university', our international outlook is a major focus and we believe in our students developing a global perspective. Many of our courses provide opportunities to study or work abroad; we have partnerships with more than 400 universities worldwide and are the only UK university to have postgraduate centres in Athens, Brussels, Paris and Rome.

The University is a truly international community with over 40% of our academics coming from outside the UK and our students representing over 150 nationalities.

We are a major economic force in south east England, supporting innovation and enterprise. We are worth £0.9 billion to the economy of the south east and support more than 9,400 jobs in the region.

In March 2018, the Government and Health Education England (HEE) announced that the joint bid by the University of Kent and Canterbury Christ Church University for funded places to establish a medical school has been successful. The first intake of undergraduates to the Kent and Medway Medical School will be in September 2020.

We are proud to be part of Canterbury, Medway and the county of Kent and, through collaboration with partners, work to ensure our global ambitions have a positive impact on the region's academic, cultural, social and economic landscape.
