U2 guitarist David Howell Evans, known as the Edge, has been announced as the co-founder of a new soil regeneration company called Oath, which uses artificial intelligence to find innovative methods to address the growing global problem of soil degradation.
Oath has regulatory approval for Ireland and the musician said the country is in a position to take a leading role on the issue, which poses a major risk to food security and biodiversity.
It is estimated by 2050, 90% of the world's soil will no longer be able to support agriculture in the way it does now.
Mr Evans, who helped form Irish rock band in 1976 in Dublin, said a friend approached him with the idea to invest in the project and when he heard about it, he said "wow".
He said he is "excited by what this could be", adding that "as a songwriter, you're trained to recognise a great melody, a great idea when you hear it".
The musician said Ireland is "doing pretty well compared to a lot of the European countries" in terms of soil quality.
However, he said: "There are parts of the world where it's a serious problem. Where Ireland could engage is more on a partnership basis. "We have regulatory approval for Ireland," he said.
"We could base ourselves here and we could scale up out of Ireland for the rest of Europe, which would be, I think a wonderful thing," he added.
In relation to his role in the project, Mr Evans said he is "fighting kind of a serious bout of imposter syndrome".

This, he said, is because he is a guitar player and "not a scientist" or farmer.
"I don't actually have any credentials here, but I'm so excited by what this could be," he said.
However, he said his "day job" in U2 is "still my priority".
"We are working on some new music that's in the pipeline," he added.
Dr Jack Gilbert, a professor of microbiology and member of Oath's Scientific Advisory Board, said "we've seen a significant increase in temperature and a significant decrease in the amount of rainfall in areas that are extremely important for agriculture" over the last 35-40 years.
"That's leading to soil drying out, becoming dead and it's compounded by over the last hundred years a significant increase in intensive agriculture," he said.
Dr Gilbert said that to help regenerate soils, Oath is developing "an artificial intelligence model that identifies all of the nuts and bolts that go on microbiologically inside the soil" and "how that interacts with the roots of the plant".
"Then we use that model to select exactly which microorganisms, bacteria and fungi are required in order to improve the health and resiliency of that soil," he said.
The company has conducted positive field trials in Rwanda in Africa, with plans to expand elsewhere.
Oath Chair Anne Finucane said they have "the ambition to be a solution for farms, grasslands and any kind of soil in the world".
"We have 200 tests to indicate that this has been effective and Rwanda is so impressed that the government there is partnering with us," Ms Finucane said, adding "they are scaling it throughout the country".
Ms Finucane said that each geographical area that Oath would be operating in "has to be bespoke".
"So we're looking at each geography separately, the manufacturing will be separate by country," she added.
The announcement was made this week at the Impact Ireland Convention in Dublin.
The annual event - hosted by Venturewave Capital - focuses on impact investment, which is a type of investment that tries to ensure financial success aligns with measurable benefits for society.
