    Researchers and students from CIRAD and CATIE, with funding from World Coffee Research, spent nearly a year taking exhaustive measurements of the movement of rust spores in a coffee agroforestry research site at CATIE in Turrialba, Costa Rica. Their findings were published in Crop Protection.

    Researchers have known for years that shade can have both positive and negative effects on coffee leaf rust—but this team wanted to understand what was behind some of those different impacts, so that better guidance can be provided to coffee farmers interested in agroforestry—an increasingly important approach for managing rising temperatu...

    In 2019, the Flor Amarilla F1 breeding program reached an exciting milestone: its first production harvest. While we have carefully monitored and measured each plants' growth since it arrived in the field, the production of cherries means that we can now gather two of the most important pieces of data on each cross: yield and cup quality.

    In fall 2017, Hurricanes Irma and Maria ripped across Puerto Rico and destroyed millions of coffee trees. It was a devastating blow: The island was on track to have the best harvest in 10 years, worth an estimated $100 million, after decades of steady decline. Across the island, not only farms were reduced to debris, but also the nurseries and seed lots that produce the baby plants the island’s farmers were going to need to rebuild.

    Which varieties are deeply affected by small changes in climate—for example, hotter, drier temperatures—and which have stable performance across a wide range of climates? How does climate impact yields, disease tolerance, or cup quality? Shockingly, there is almost nothing known about the effects of environment on coffee tree performance.
