This new grant scheme will enable local community volunteers to make a contribution to their village or parish.
Funding will be available for built environment or environmental projects.
It can be used towards the cost of tools or professional support.
Initially, £5,000 is available in the fund until April 2019, although it is hoped that the scheme will continue for further years.
Grants will normally be in the range of £750 to £1,000.
In general, the scheme will provide 100 per cent funding, although this is at the discretion of the advisory panel.
The grant scheme is open to those based in, or operating in, any parish within or adjacent to the AONB (which runs along the coast between Amble and Berwick).
The scheme complements the existing Sustainable Development Fund run by the AONB Partnership, which provides grants of up to £3,000 for projects that benefit the environment, communities and visitors to the AONB.
Gary Campbell, Coast Care project coordinator, said: “This exciting new funding opportunity will help to give volunteers the tools to make a real difference in our area.”
