Academics in export agriculture highlighted that 50% of the land in the Central Highlands were marginal and degraded lands which were presently on the verge of desertification.

Lands formerly used by tea plantation and estate companies have been deserted as according to them, the lands could not be made to bear yield any longer even if fertilizer was used as the soil and soil structure had weakened to such an extent.
