Incentivising biodiversity net gain with an offset market


A new policy has been put forward in the fight to preserve biodiversity, calling on the private sector and borrowing from market economics.

One of the main drivers of biodiversity loss is the habitat destruction due to changes in land use. According to the IPBES- Intergovernmental Science- Policy Platform on Biodiversity and Ecosystem Services’ report published in 2019, 75% of global land has in some way been altered by human development.

Even if the need for effective conservation policies is growing stronger, most biodiversity conservation programmes are financed only by the public purse. This is the case for habitat restoration policies in the UK, with an estimated cost of around £97 million per year.

In addition, it is no longer enough to simply reduce biodiversity loss in a given area; a global movement is now pushing for conservation policies aimed at producing a net gain in biodiversity. This means an actual increase in the biodiversity of the area.

This paper investigates the opportunities of involving the private sector in environmental conservation policies through an offset market strategy.

The biodiversity offset market works according to the economic model of marked operation based on supply and demand curves. Farmers who change their land management will earn credits that can be sold to housing developers.

Eight policy scenarios have been compared in the paper, from the complete lack of conservation policy to the request of a net gain up to 50%. The operations, costs and biodiversity impacts have been calculated using an ecological model that links the land management with the bird population.

We have used AlphaGalileo since its foundation but frankly we need it more than ever now to ensure our research news is heard across Europe, Asia and North America. As one of the UK’s leading research universities we want to continue to work with other outstanding researchers in Europe. AlphaGalileo helps us to continue to bring our research story to them and the rest of the world.

AlphaGalileo has helped us more than double our reach at SciDev.Net. The service has enabled our journalists around the world to reach the mainstream media with articles about the impact of science on people in low- and middle-income countries, leading to big increases in the number of SciDev.Net articles that have been republished.
