The role of space technologies in integrated water resources management
On a sweltering summer day along the banks of the Mekong River, villagers in Laos watched nervously as water levels fell dramatically. Upstream, hydropower dams in China had altered the river’s flow, leaving communities downstream scrambling for water to irrigate crops, sustain fisheries, and meet drinking needs. This scene is far from unique. Across the world, transboundary rivers are flashpoints of tension, where one country’s energy or agricultural ambitions can ripple downstream, affecting millions of people (UNESCO 2023). Global water stress is escalating at an unprecedented pace.
