Impact of frost

The best quality Arabica coffee is grown at higher altitudes, above 1,000 metres, but this makes the crop vulnerable to cold temperatures.  Coffee bushes are easily damaged or killed by frost, resulting in a loss of income for farmers.

Climate change is increasing the risk of extreme weather, and coffee farmers in the North of Laos have experienced frost twice in the past 5 years.  The amount of damage has been different from place to place, depending on where the crop is planted.  The experience in Keoset shows that coffee planted in natural forest is less vulnerable that coffee planted in the open.
