Award-winning entomologist Dino Martins, known for his work on pollinators, shows in his latest book that even the most gruesome creatures have vital roles to play

Dino J Martins has never been able to resist the small things. The renowned entomologist and evolutionary biologist spent his formative years in biodiversity-rich western Kenya with his foster parents, Joe and Sarah Ellen, looking at birds, flowers and insects on Mt Elgon, and in Kakamega forest and Kerio valley.

He was especially transfixed by the miniature world beneath his feet – dung beetles rolling mounds of cattle dung; safari ants’ migrations across the plains; male butterflies that suck salt and other nutrients from the mud to produce “nuptial gifts” during mating; and bees pollinating the critically endangered African violet alongside crops in a farmer’s field.

Conserving the watershed of the Tana and improving farming methods is securing water supplies and livelihoods alike in a changing climate

When in 2017 David Nyoro became one of the first farmers to partner with Africa’s first water fund to conserve the watershed of Kenya’s biggest river, he received 180 high-value avocado seedlings. The 67-year-old’s farming methods had been dominated by annual crops that left large sections of his five-acre piece of land bare, increasing soil erosion and contributing to river sedimentation. “We used to lose a lot of topsoil to the river. Such loss of soil nutrients and poor farming practices meant we had less farm produce,” he says.

The avocado seedlings enabled him to grow his farm income to close to 2m Kenyan shillings (about £11,500 at today’s exchange rates), with each mature avocado tree yielding 70kg (154lbs) annually. He introduced cover crops to improve soil health and reduce soil erosion and sediment loads.
