Although the unproductive uplands ('dead lands') in Java are now reafforested or terraced, the crop productivity is still low in particular on volcanic soils. Sources of erosion are briefly discussed. It was concluded that the low productivity of upland farming systems was caused by low inputs and not by surface erosion and a redirection of soil conservation policy, planning and research is required.
