Marginal uplands are hilly or mountainous lands having very low crop productivity due to poor soil quality (degraded soil), limited water availability, and unfavorable socio-economic conditions. They are widespread in Southeast Asia and other parts of the humid tropics (e.g., Agustin and Garrity 1995; Asio et al., 2009). Resource poor-farmers (~ 1.4 billion people) in the developing world are located on these risk-prone marginal environments (Altieri 2002).  Marginal uplands in Inopacan and Hindang, Leyte In the Philippines, the poorest households, who are also the most vulnerable and most food insecure, are living and farming on these marginal lands (Roa 2007). The agro-ecological conditions in these areas are typically not suited to intensive production systems due to low-quality soils, hilly slopes, limited access to inputs or markets and extremely diverse and site specific conditions (Asio et al., 2009; Tyler 2004). Crops that can be grown on these marginal lands are often restrict
