Upland farms which largely produce subsistence crops take the heaviest toll from increasing population pressure. Sloping areas in the Philippines have been shifted to a permanent and more intensive farming. Similarly, farmers' tendency to shift towards cash crops, cassava in particular, without the benefit of external soil nutrient usage has contributed to soil degradation. This study investigates the sustainability and productivity of intensive farming under unfavorable upland environment. The study was based on a two-part intensive household surveys in Claveria, Misamis Oriental i.e. 1992 survey and record keeping data from 1986. The paper investigates farm level changes in land use patterns, the profitability of cultivating alternative crops and cropping patterns, and the changes in productivity and resources use efficiency associated with changes in farming systems
