North Devon and beyond Roaring deer and singing wrens, mossy scree and ferny oaks, the swish of the sea and other snapshots of a 100-mile walk

The sight and sound of sea accompanies half our 100-mile walk from Braunton Great Field almost to Taunton, south of the Quantocks. From the coastal path, distant views of Lundy give way to those of south Wales, sometimes catching light from the lowering sun, but more often masked in cloud. Low tide reveals shining sand at Saunton; a swimmer heads for flat water off Croyde to “bob around” on his afternoon off.

Next morning at Woolacombe, surfers ride big waves before dawn. That day, drizzle enhances the vividness of green grass and orange bracken between the slippery jagged slate of Morte and Bull Points, above vertiginous cliffs and tiny coves scattered with lumps of quartz. The zigzag descent to Ilfracombe was engineered for Victorian tourists, as were the resort’s tunnels, bored through cliffs towards tidal bathing pools.

Study also finds that converting conventionally farmed land would not overly harm crop yields or require huge amounts of additional land to feed rising populations

Converting land from conventional agriculture to organic production could reduce greenhouse gas emissions, the run-off of excess nitrogen from fertilisers, and cut pesticide use. It would also, according to a new report, be feasible to convert large amounts of currently conventionally farmed land without catastrophic harm to crop yields and without needing huge amounts of new land.

The study, published in the journal Nature Communications, found that by combining organic production with an increasingly vegetarian diet, ways of cutting food waste, and a return to traditional methods of fixing nitrogen in the soil instead of using fertiliser, the world’s projected 2050 population of more than 9 billion could be fed without vastly increasing the current amount of land under agricultural production.
