The world’s population is expected to reach 9 billion by the year 2050. Producing enough food for our growing planet may be the single greatest challenge the world will face. To meet this huge demand, farmers, ranchers, and suppliers must find ways to produce more food in a sustainably, environmentally friendly way.

ARS is dedicated to helping farmers address the increasing global demand for food, feed, fiber, and fuel while also sustaining the environmental and economic viability of agriculture. As a multidisciplinary practice and philosophy, sustainable agriculture unites researchers from a diverse range of scientific studies — microbiology, animal nutrition, soil science, plant physiology, and more — to the common goal of overcoming challenges related to productivity, profitability, energy efficiency, and natural resource management.
