Relative importance of common bean attributes and variety demand in the drought areas of Kenya

Abstract

The analysis assessed the relative importance of production and consumption attributes to different wealth groups
of households and tested the effect of attribute preference and that of other factors on common bean variety demand
in the drought areas of Eastern Kenya. Variety demand was conceptualized within the agricultural household
framework and attributes were incorporated into the model according to the Lancaster (1966) consumer theory.
Empirical analysis was based on primary data collected from two districts of Eastern Kenya using the stated
preference and revealed preference methods. A factor analysis was used to cluster a set of common bean variety
attributes that are highly preferred by households into those related to consumption flavour and yield related
characteristics. The effect of consumption and production attributes and those of other factors were estimated
through applying ordinary least squares regression. The study findings reveal that varietal adaptation to
environmental stresses should also strive to reduce the cooking time as well as enhance the keeping quality and
grain colour for better benefits to the poor but trade-offs are feasible. Prioritizing the improvement of production
attributes as a short term goal seems an efficient strategy when multi-attribute based breeding is a long process.
