That thinking runs through 51° 46 10.01 N 3° 59 05.93 W (Tan-y-Garn), a 2026 painting made using ochre collected from a former mine in the Welsh Valleys. Once famous for coal mining, the region still bears the marks of this history, from environmental damage to the wider afterlife of extraction. McCausland uses pollution as a tangible sign of a changing landscape, bringing mine water pigment and iron powder into the work as medium and record. Her paintings follow the same logic as the land itself: layers accumulate, sediments erode, something new appears and something older is buried, though never erased. Yianni points to this commitment to origin as what distinguishes the practice. “Many artists speak of landscape; Onya works with it,” she says.
“Many artists speak of landscape; Onya works with it.”
That balance between the poetic and the purposeful extends far beyond the studio. McCausland is about to open Tailings, a large-scale solo exhibition with Yianni at CLOSE Gallery in Somerset, while also working on a book project with Finnish writer and curator Mika Hannula, due for publication later this year. A forthcoming collaboration with chemical engineers at Witwatersrand University will focus on waste materials at a former gold mine near Johannesburg. Alongside this work, she leads Seeds of Feral Thought at the Slade School of Fine Art, a research group exploring alternative and experimental approaches to ecology and sustainability at the intersection of social, racial and environmental justice through artwork, writing, performance and film.
Asked about her biggest achievement to date, McCausland points to completing a doctorate, something she describes as entirely beyond the expectations of her younger self. It is a telling answer for an artist whose practice is built on inquiry and rigour. On Earth Day, her work offers a powerful reminder that landscape is never neutral: it holds the traces of what has been taken from it, what has been left behind, and what painting can still bring to the surface.
