Common bean is the second most important staple food grain consumed in Central America. Since 1980, the national research centers in the region, in collaboration with Zamorano, CIAT and the DGP/CRSP, have provided farmers with many improved bean varieties (IVs) to help increase yields, incomes and food security. In the past six years, many governments have implemented seed distribution programs to promote the use of IVs to increase food security. Therefore, it is important to know current country- and regional-levels of adoption of IVs and to determine the benefits of these initiatives at the regional level. This study is a step in that direction. The main objectives are to estimate adoption rates of IVs in five Central American countries and to evaluate the economic impact of adoption of IVs in the region. Bean experts (e.g. researchers, government officials) were interviewed in each country during 2010. In addition, secondary data were collected. Adoption rates were estimated using this information. To assess economic impact in the region, a consumer surplus analysis will be conducted. Preliminary results suggest that land area planted to IVs was highest in Nicaragua and lowest in Guatemala. However, the percentage share of total bean area was highest in Costa Rica and lowest in Guatemala. The IV most widely adopted in the region was Amadeus 77. Additional results and discussion will be provided.
