Biodiversity conservation is vital to sustainable development. Many development sectors currently impact biodiversity, but all are ultimately reliant on the ecosystem services it provides. The BirdLife Partnership therefore works with governments, businesses and financial institutions to help them avoid or minimise negative impacts on priority sites—such as IBAs—and to harness effectively the many benefits they deliver. IBA mainstreaming occurs when the value of IBAs are recognised within productive, financial or development sectors—such as agriculture, finance, or health—and their conservation is integrated into the goals, policies, strategies and practices of these sectors. Mainstreaming can lead to a range of positive outcomes, from influencing national budget decisions to changing the behaviour of corporates.
