Investments over the past 35 years have created a system of national and international research centers that has revolutionized the supply of improved cereal varieties to developing country farmers. The newly created scientific ability to exploit genetic resources has been the engine of...

We used a disaggregate approach to examine investment efficiency of wheat breeding research in India. India's total research effort comprizes 20 research programs spread across 50 experiment stations. A technology spillover matrix was constructed for both potential and actual spillovers....

Tomato, cabbage and garden egg (African eggplant, or Solanum Aethiopicum) are important crops for small-scale farmers and migrants in the rural and peri-urban areas of Ghana. Genetic modification (GM) has the potential to alleviate poverty through combating yield losses from pests and diseases...

Sorghum is one of the world’s most important cereals in terms of total production. Grown largely as livestock feed in the US, sorghum is a primary food staple and source of cash for smallholder farming families in the West African savannah. The dominant type of sorghum produced in this region...

Land degradation cripples smallholder crop production in Sub-Saharan Africa, including those found in the densely populated, grain basket areas of Kenya. Research in the early nineties already documented and rated nutrient depletion to be very high in the east African Highlands. Whereas some of...

Since 2002, the United States Agency for International Development (USAID) has funded programs to promote maize, dairy, and horticulture enterprises among smallholder farmers in Kenya under the Strategic Objective 7 of Increased Rural Household Incomes. On behalf of USAID, Tegemeo Institute has...

The objective of this study is to evaluate pesticide use as an important factor affecting potential adoption and farm level impact of genetically modified (GM) vegetable varieties in Ghana. Tomato is the most consumed vegetable and a food security crop. Cabbage is a vegetable of growing...

Bt maize in Kenya is promising biotechnology innovation for poor households. Econometric prediction from a trait-based model of variety adoption indicates that the choice of host variety has equity and efficiency implications related to heterogeneity in maize growing environments and pest...
