The Cooperativa Agroindustrial de Carlópolis (Coac) in Carlópolis, north of Paraná, Brazil, has seen a remarkable 580% increase in guava exports from 2020 to 2023, reaching 113,703 kg, thanks to the guava's Geographical Indication (GI) and Global G.A.P seal. This success is a result of collaborative efforts between Coac, Sebrae/PR, Carlópolis City Hall, and IDR-Paraná, highlighting the importance of joint work and certification in opening international markets and improving the livelihoods of local producers. Despite facing challenges such as climate effects and a need for more human capital, the initiative has not only boosted exports but also expanded Coac's presence in the domestic market, demonstrating the positive impact of organized production and certification on regional development and the economic well-being of small rural producers.
