In hyper-arid environments, resilience begins at the smallest scale – the seed. Saudi Arabia’s new seed-based restoration programmes signal a shift from reactive land management to proactive ecological renewal. They also offer lessons for how urban development, cultural investment, and ecological systems must grow together if sustainable cities are to take root.
Cities are shaped as much by light as they are by stone and steel. Yet in today’s urban environments, natural sunlight is rarely treated as a design priority.

Why Life Is Better with a Little More Green? As cities grow denser and hotter, science points to one clear remedy: green space. Here’s what science says about how greenery sustains our bodies and cities.
