Berkeley Rausser College of Natural Resources

Agriculture, natural resources sectors support California’s rank as world’s fourth-largest economy | ANR News Releases California landscapes are diverse, featuring conservation lands, productive farms and innovative renewable-energy projects. A new report from UC ANR quantifies their value.

Analysis by Cooperative Extension Professor Ali Hill and collaborators at @ucanr.edu indicates that California's working landscapes—the farms, ranches, mines, forests, renewable energy installations, and fisheries—generated $404 billion in sales income in 2024.

Assistant Professor @ornithoale.bsky.social and alum @beckyck.bsky.social join a @ucsantabarbara.bsky.social-led team of scientists who say Earth science information can do more than quantify the instrumental or monetary value of nature—it can also measure social good. news.ucsb.edu/2026/022371/...
