The total acreage of Vietnam's coffee crop must be reduced by 20-30% to between 420,000 and 462,000 ha in order to prevent a crisis of over production, according to the Vietnam Coffee and Cacao Association (VCCA). In response to the warning, the country's coffee acreage is now expected to fall by between 150,000 and 180,000 hectares with the central highlands provinces of Dac Lac and Lam Dong reducing crops by 70,000 ha and 40,000 ha respectively. Other coffee-growing provinces will slash production by 70,000 ha.
