The impact of improvement research: the case of Bangladesh and Ethiopia.

Abstract

This chapter discusses the state of adoption of improved lentil cultivars in Bangladesh and Ethiopia using survey data, the factors constraining the diffusion of new lentil cultivars, the ex post economic impacts based on the adoption that has already taken place, and the costs of the time lag in new lentil cultivar adoption. The chapter is organized in 8 sections. The first section provides an overview of lentil research and development. The second section introduces the study areas and the third section describes the household surveys. The fourth section provides estimates of the profitability of new lentil technologies. The fifth section documents the adoption of new lentil cultivars. An analysis of the factors influencing the adoption of new lentil cultivars is presented in the sixth section. The economic impacts of lentil improvement research and the methods used in estimation are discussed in the seventh section. A discussion of results, their implications or lessons for research and extension are presented in the eighth section.
