Table 2. Calculation of earnings from coffee based on survey data, under three scenarios.

(1) Baseline scenario (non-specialty coffee, total harvest used to produce sundried coffee); (2) Improved scenario, where 75% of harvest is used to produce sundried coffee and 25% goes into specialty (via the washed coffee processing method), which represents the current mode for the five Yayu cooperatives; and 100% specialty scenario, where all the harvest goes to specialty/washed coffee. *Under all scenarios 351 kg of coffee is produced, from 2,106 kg of fresh cherry. Clean coffee produced via the sundried route, requires a twostep process Fresh cherry to sundried conversion is at ratio of c. 3:1 (i.e., 2,106 kg/3 = 702; and conversion of sundried cherry to clean coffee is at a ratio of 2:1 (i.e., 707/1 = 351 kg). The overall conversion rate (ratio), from fresh cherry to clean coffee is thus is 6:1. ETB, Ethiopian Birr; US$, US Dollar. Exchange rate of 1 US$ to 23 ETB. Bold indicates key total values.
