Newswise — New data has found that natural habitats occupying an area larger than Greece have been created to offset economic developments. This data could eventually provide a basis to help improve our understanding of the benefits of protecting and preserving wildlife. Called 'biodiversity offsets', man-made conservation areas are created to compensate for economic developments and are a growing trend.

They include major industrial projects like the Oyu Tolgoi copper mine in Mongolia and the Bujagali hydropower project in Uganda and at the other end of the scale, grassland restoration offsets only one hectare in size to compensate for housing developments in the UK. Until now, no one has had enough information to assess whether they work on an international scale.

Dr Joseph W. Bull, a conservation scientist at University of Kent worked with Dr Niels Strange from the University of Copenhagen to collate data on over ten thousand examples of nature sites created specifically to compensate for industrial impacts. The researchers found that across the world businesses are offsetting their development at a 'rapid rate' - from international corporations to smallscale landowners. The researchers also found there were more offsets than they expected - 12,983 projects across 74 countries.

Dr Bull said: 'This is the start of something major. Biodiversity offsets are being implemented very quickly despite being quite a recent policy idea. More than 153,000 square kilometres is a big chunk of land and - for the first time - we now have a dataset that can and will be used by two hundred countries across the world to refine "no net loss" policies, seeking to protect our natural environment.'

'No Net loss' policies are the point at which the project-related impacts on biodiversity are balanced by measures taken to avoid and minimize their impacts.

Such a global dataset is the prerequisite for assessing how well offsets compensate for biodiversity impacts associated with economic development, adds Dr Strange.

The data also showed that emerging economies (particularly in South America) were more dominant in terms of global offsetting and most projects are very small. However, the researchers also note that the overwhelming majority (99.7%) of projects are implemented by law rather than on a voluntary basis.

The data is being made available to the Global Inventory on Biodiversity Offset Policies (GIBOP), currently being officially promoted at the thirteenth meeting of the international Convention on Biological Diversity, to be attended by up to 196 member countries in Egypt from the 17th-29th November 2018.

The global extent of biodiversity offset implementation under no net loss policies, by Joseph W. Bull and Niels Strange, is published in Nature Sustainability.

Gold for Kent in Teaching Excellence Framework (TEF)

Established in 1965, the University of Kent - the UK's European university - now has almost 20,000 students across campuses or study centres at Canterbury, Medway, Tonbridge, Brussels, Paris, Athens and Rome.

It was ranked 22nd in the Guardian University Guide 2018 and in June 2017 was awarded a gold rating, the highest, in the UK Government's Teaching Excellence Framework (TEF).

In 2018 it was also ranked in the top 500 of Shanghai Ranking's Academic Ranking of World Universities and 47th in the Times Higher Education's (THE) new European Teaching Rankings.

Kent is ranked 17th in the UK for research intensity (REF 2014). It has world-leading research in all subjects and 97% of its research is deemed by the REF to be of international quality.

Along with the universities of East Anglia and Essex, Kent is a member of the Eastern Arc Research Consortium (http://www.kent.ac.uk/about/partnerships/eastern-arc.html).

The University is worth £0.7 billion to the economy of the south east and supports more than 7,800 jobs in the region. Student off-campus spend contributes £293.3m and 2,532 full-time-equivalent jobs to those totals.

Kent has received two Queen's Anniversary prizes for Higher and Further Education.
