History
Most of the original coffee plants brought to the New World from European countries would burn in the sun, which made shade necessary for growth. However, over the past 30 years new sun tolerant trees/shrubs have been developed in response to fungal disease presence, especially coffee leaf rust (Hemileia vastatrix), and with the aim to yield higher production rates. As a result of modernization and a push for higher yielding crops, sun tolerant coffee plants were created to produce three times more coffee than a shade bush in a year, but the cultivation practices used for them are considered unsustainable and often have a negative impact on the environment. This has resulted in a new trend in support of shade-grown coffee.
