Agriculture is comprised of managed ecosystems, which can include forests, rangelands
and crops; these managed ecosystems are vital resources, providing a host
of economic and societal benefits. However, these systems face a multitude of
challenges: from climate change and limited natural resources; to exotic pests and
pathogens; to growing global populations and food demands. Responding to these
global challenges requires interdisciplinary innovation and strategic planning to
maintain production and sustainability while responsibly feeding the future. The U.S.
Department of Agriculture and its Research, Education, and Economics, and Forest
Service agencies plan to meet these challenges via research programs and initiatives.
