China’s straw grids are helping deserts shrink by over 1,000 sq km a year

Across the deserts of northern China, a quiet, repetitive movement has played out for nearly 50 years: People bending down, pressing long straw bundles into shifting sand, then planting tiny saplings in the empty squares they’ve created.
