An environmental project is set to almost double in size.
Galloway and Southern Ayrshire Biosphere has had its UNESCO status extended for another decade.
And part of that will see its boundary changed to cover the Rhins of Galloway, some of the Solway Firth and more of Ayrshire, extending its area from 5,200 square kilometres to nearly 9,800 sq km.
The news was confirmed by a UN delegation at a reception at Drumlanrig Castle, Thornhill.
Biosphere chairwoman, Melanie Allen, said: “I welcome the news of the revalidation of our precious designation. We are truly honoured to be recognised by UNESCO with an ambassadorial visit to mark the occasion.
“This is a significant milestone and excellent news for our communities, businesses and partners. Their continued dedication to the biosphere unites us with a shared vision and passion for sustainable rural economic development, through best practice and partnership working.”
She added: “The ground-breaking work that has already been delivered in partnership with our dedicated Biosphere team is absolutely astounding. We can’t wait to see what the next 10 years brings.”
UNESCO granted the area Scotland’s first biosphere status in 2012.
Achievements since then include the launch of the Biosphere Certification Mark, which recognises examples of sustainable enterprise, the creation of a learning for sustainability toolkit and a Blackface wool project.
Head of research and policy for UNESCO’s Biosphere programme, Meriem Bouamrane, said: “The Galloway and Southern Ayrshire Biosphere is an inspiring, internationally recognised place for living, which is reconciling conservation and sustainable use of biodiversity.
“We are absolutely delighted to announce that we will be renewing its designated status for a further 10 years, including an expansion of its geographical boundary.”
Earlier this year, Dumfries and Galloway Council agreed to grant the project £30,000 a year for the next five years, with the organisation working on a new base in Dalry.
“Our renewed and expanded UNESCO biosphere designation will allow us to build on this and do so much more to support our vision for a just and equitable approach to life where people and the environment are both given equal consideration.”
