Ethiopian coffee yields threatened by climate change
Climate change | Africa
July 13, 2020 – By 2030, coffee farmers in Ethiopia and corn producers in Mozambique will have a full percentage point higher chance than they do today of experiencing a 25 percent or greater drop in annual yield. Conversely, cotton yields in Mozambique would become more stable.

Bar Chart and Choropleth Map: African crop-yield risk comparison for Mozambique and Ethiopia.
Layout / body structure
The chart compares Mozambique and Ethiopia side by side. Each country has a map highlight, crop-specific bar comparisons, and climate-driver notes explaining why yield risk changes.
What is being compared
It compares the likelihood of extreme yield changes for selected African crops: cotton and corn in Mozambique, and wheat and coffee in Ethiopia. The bars compare today’s likelihood with the projected 2030 likelihood.
Measurement system
The bars measure likelihood of extreme yield changes as a percent. The thresholds distinguish at least 10 percent and at least 25 percent yield declines.
Visible structure inside the graphic
Mozambique’s cotton bar is visibly higher than the other crop bars, while Ethiopia’s coffee and wheat bars are smaller but rise by 2030. The notes below each country separate positive and negative climatological drivers.
Main takeaway from the visual
The chart shows that climate-change effects on African crop yields are uneven. Some crop-country combinations face substantially higher risk, while others show smaller changes or more stable outcomes.
Key standout values or extremes
Mozambique cotton has the highest visible risk, with a 17.5 percent likelihood at the 10 percent yield-decline threshold today. Ethiopia coffee rises from about 3.2 percent today to 4.2 percent by 2030 at the same threshold.
