Coffee is Getting Less Green

April 16, 2014 1:13 pm | by The Univ. of Texas at Austin | News | Comments

The proportion of land used to cultivate shade grown coffee, relative to the total land area of coffee cultivation, has fallen by nearly 20 percent globally since 1996. Researchers say the global shift toward a more intensive style of coffee farming is probably having a negative effect on the environment, communities and individual farmers.
