Symposium : Ensuring Net Gain for biodiversity and people

, 10
Lecture theatre: The Oxford Martin School, 34 Broad St, Oxford, OX1 3BD


On the 20th of November 2018, a symposium was held to launch a set of good practice principles “Ensuring No net Loss for people as well as biodiversity”.

Thank you to all those who participated!






lunchGovernments, businesses and lenders worldwide are increasingly adopting biodiversity targets of No Net Loss (NNL) and ‘Net Gain (NG) for development projects. While ecological challenges to achieve NNL/NG are debated, the associated gains and losses for people have received less attention. International best practice suggests that NNL/NG initiatives should make local people ‘no worse off’ and preferably ‘better off’. However, there is a lack of clarity concerning how to achieve this with regard to people’s use and non-use values for biodiversity, especially given the inevitable trade-offs when compensating biodiversity losses with gains elsewhere.




discussionsThe aims of this symposium were to:

• Increase our understanding of the negative and positive impacts on people from biodiversity NNL/NG

• Share experiences in efforts to ensure people are ‘no worse off and preferably better off’ from biodiversity NNL/NG

• Discuss ways forward for biodiversity NNL/NG projects to result in the best possible outcomes for both biodiversity and people

• Launch a new set of good practice principles for biodiversity NNL/NG projects to generate benefits for both biodiversity and people
