Climate change is the major threat to the stability of agricultural production particularly in marginal hilly areas. Marginal hillylands, being generally eroded, nutrient deficient, and of low water storage capacity, are highly vulnerable to abnormal weather-related risks. Thus, utilization of these areas for food production requires a science-based system of selecting crops that are highly suitable to the biophysical and socio-economic conditions in marginal hilly areas. The study was conducted at Brgy. [Village] Masalukot-4, Candelaria, Quezon from August 2013 to June 2014. The main objective of the study was to come up with science-based recommendations on the selection of alternative staple crops suitable to marginal hilly areas. Performance of the two crops, cassava and sweet potato, was evaluated in terms of their ability to conserve soil nutrient and water, soil organic matter accumulation, microbial population and activity, and yield. Initial evaluation showed the comparable effects of cassava and sweet potato on soil pH, NPK content, organic matter level, moisture content, microbial population and activity, and crop yield.
