At the Starbucks 2016 Annual Meeting of Shareholders this week, president and chief operating officer Kevin Johnson played a video of the company’s agricultural research center in Costa Rica to highlight the company’s emphasis on creating a sustainable supply of coffee for future generations.

Johnson announced that Starbucks in on track to donate 20 million rust-resistant coffee tree seedlings to farmers this year through its One tree for Every Bag commitment. He also talked about visiting coffee farms in Costa Rica earlier this year, including Hacienda Alsacia, Starbucks first coffee farm and a center for global agronomy research.

Starbucks efforts to create a sustainable supply of coffee is supported by the company’s open-sourced ethical sourcing program, C.A.F.E. Practices. The program offers agronomy information, tools and financing for farmers worldwide in collaboration with Conservation International.

C.A.F.E. Practices include guidelines for quality, economic accountability and transparency, social responsibility and environmental leadership that help farmers grow coffee in a way that’s better for people and the planet.

Over the last few years, The Costa Rica Star has been reporting on this Starbucks research center, which is located on the skirts of the Poas volcano in the province of Alajuela. Hacienda Alsacia has been operating as a coffee plantation since the 1970s; prior to becoming a research center, this farm was an important supplier of quality beans for Starbucks.

In the first year of operations, Starbucks harvested more than 300,000 pounds of coffee at Hacienda Alsacia. In a nursery at the farm, thousands of seedlings are being grown to test new coffee varietals that improve disease resistance, quality and yield.

Starbucks operates similar research centers in Colombia, Rwanda, Tanzania, and even China.
