The Delicate Balance of Protecting River Deltas and Society

Hundreds of millions of people live on river deltas around the world, making them central to rich diversity in culture and thriving economies.

Hundreds of millions of people live on river deltas around the world, making them central to rich diversity in culture and thriving economies. As deltas face environmental degradation and ongoing climate change, governments have sought ever more drastic measures to prevent flooding and protect society and its infrastructure. But, these policies can harm the natural environment and lead to loss of precious land. Striking a balance between limiting deltaic land loss and maximizing cultural and economic benefit to society is a top priority in sustainability policy.

Researchers at The University of Texas at Austin and Texas Tech University created a novel analysis tool that seeks to protect the millions of people living on urban river deltas, while preserving the environmental and commercial viability of these landscapes. Their study, published today in Proceedings of the National Academy of Sciences, applies a cost-benefit model to the concept of delta management, for the first time, by examining how to balance the natural function of river deltas with societal desire for landscape stability.
