Farmers' decision making strategies on selecting rootcrop varieties in the Visayas Region, Philippines

In the Philippines, rootcrops play a significant role in providing livelihood and food security among the resource poor people living in fragile upland environment, which comprise about 65% of the total agricultural land in the country. This paper will present the factors which play into farmers' decision-making strategies for varietal adoption, particularly of sweetpotato and cassava in Visayas Region, Philippines. Relative importance of factors as they are considered in the farmers' decisionmaking process vary according to user-orientation (i.e. subsistent, semi-commercial and commercial) because such would have varietal trait specifications, scale of operations, and consequently, resource needs. In largely market or industry-oriented systems, the economic factor is observed to be more important. The market requirement of varieties is enough motivation to grow a variety subject to resource constraints. Further, the degree of intensity of factor or constraint could be location specific due to natural endowments (e.g. land quality), farming systems, and social relations. But in the absence of markets or profitable use, adoption of a new variety is a difficult choice. Overall, given the complexity of circumstances that are factored in the farmers' decision-making strategies to sustainably adopt varieties from the farmers' own sphere to that of the institutions (i.e. Research and Development policies), any research and development activity that hopes to eventually make the farmers' lives better through the adoption of technologies should be designed with a greater partnership between the natural-technical and social scientists, the local partners and communities.
