COOPESER is a Brazilian cooperative founded on November 7, 2007, focused on consulting, research, and services that support sustainable rural development. It brings together professionals and seeks to create opportunities for members to practice and improve their professional skills. The cooperative provides technical assistance and rural extension to family farmers, traditional peoples and communities—including quilombola, Indigenous, riverside, forest and artisanal fishing communities—as well as women, young people, older adults, and agrarian reform settlers.

Its mission includes delivering technical assistance, consulting, research, services, technology dissemination, and social advisory support through participatory methods. COOPESER’s work is guided by the principles of agroecology, solidarity economy, and fair and solidarity-based trade. The cooperative also pursues members’ professional development and cooperates with public and private specialist organizations to support technical training and cooperative education. Its website features information about the organization, documents, transparency, projects, partnerships, and services. COOPESER is based in Bahia, Brazil, and can be contacted by email or telephone.
