Electronic theses at the Benson Institute deal with real-world application of advanced research sponsored by the Benson Institute. Most theses are written in Spanish with translated English titles and abstracts.

The Ezra Taft Benson Agriculture and Food Institute is a 501 (C3) Corporation owned by The Church of Jesus Christ of Latter-day Saints (LDS Church) and operated as a subdivision of the Church's Welfare Department that has as its goal the improvement of the nutrition and health of the rural poor.

The Institute was originally formed as part of the Brigham Young University (BYU) College of Biology and Agriculture in 1975. It was named for Ezra Taft Benson, a U.S. Secretary of Agriculture, president of the LDS Church, and an advocate for the well being of farmers. The institute still maintains ties to BYU but in January 2008 it separated organizationally from BYU and became part of the LDS Church's Welfare Program.

The Benson Institute has focused on Ecuador, Bolivia, Mexico, Guatemala, Morocco, and Ghana.
