The Central Highlands province of Dak Lak needs a proper land use strategy to mitigate soil erosion and develop existing land resources, scientists have recommended.

The rain had swept away a lot of nutrients in the arable land, resulting in soil degradation.
The volume of eroded soil on cultivated and uncultivated land is 7.7-33.6 tonnes and 51.8 tonnes, respectively, per hectare per year.
Intercropping could help improve land fertility and stimulate crops’ growth, Tu suggested.
Growing coffee and bean together, for example, is an effective combination, which could preserve land for the coffee cultivation. The initiative could safeguard 25 tonnes of land from erosion per hectare per year.
Tu also suggested Dak Lak and other Central Highlands provinces take measures to improve the organic matter in land, especially making use of available organic materials such as leaves and weed-trees.
Increasing forest coverage and reorganising plant structure are among solutions to that issue, he added.
