Your Life Depends on It

There is no life without phosphorus. It’s in your bones. It’s in your DNA. As a key fertilizer ingredient, phosphorus is essential for global food security.

As a burgeoning world population harvests more crops for food, energy, and materials, the demand for phosphorus increases. Yet our phosphate rock reserves are non-renewable, increasingly contaminated, and highly concentrated geographically, posing geopolitical vulnerability. Meanwhile, intensified phosphorus use has degraded water quality in rivers, lakes, and coastal oceans, creating toxic algal blooms and dead zones. Our global water security also depends on better phosphorus management.

Our Vision

We envision a food system that manages phosphorus more sustainably to provide abundant, nutritious food while protecting the health of rivers, lakes, and oceans.

Allies Addressing a Complex Problem

The Sustainable Phosphorus Alliance is a membership organization addressing the complex problem of phosphorus sustainability. We are North America’s central forum and advocate for the sustainable use, recovery, and recycling of phosphorus in the food system. We collaborate with our members and supporters to innovate and implement evidence-based solutions to the phosphorus sustainability challenge, to be shared and accessible to the community.

The Sustainable Phosphorus Alliance is a unit of the Julie Ann Wrigley Global Institute of Sustainability at Arizona State University. Our activities to advance phosphorus sustainability and benefit our members are funded by membership dues and contributions.
