Agricultural Representation for the United States Territories Act This bill increases agricultural representation for U.S. territories on the National Agricultural Research, Extension, Education, and Economics (NAREEE) Advisory Board. Specifically, the bill increases the advisory board membership to 16 members (from the current 15). The additional member must represent the agricultural interests of Puerto Rico, the U.S. Virgin Islands, American Samoa, the Northern Mariana Islands, and Guam. The bill also extends the advisory board through FY2028. (The NAREEE Advisory Board advises the Department of Agriculture, land-grant colleges and universities, and Congress on top priorities and policies for food and agricultural research, education, extension, and economics.)
