There is a direct correlation between crop diversity and pest and disease control. When farmers grow varieties with uniform resistance to a pest or disease, crops can become more susceptible to attack by bacteria or viruses, and epidemics can result. The resulting food and economic losses also show how pests and diseases are continuously evolving [...]

Much of the 30% of the world’s annual harvest lost to pests and diseases occurs in developing countries. The resulting economic and food resource costs are, to a significant extent, a consequence of crops growing in monocultures and the continuing evolution of new races of pests and pathogens that are able to overcome resistance genes [...]

The effects of climate change on potential abiotic stresses are well known. Changes in CO2 concentration, increased temperature, increased drought, changing on rainfall patterns have all been documented in the IPCC reports (http://www.ipcc.ch/publications_and_data/publications_and_data_reports.shtml) and in several recent publications. The effects of climate change will be different in different parts of the world and there exist [...]

Our team in Uganda led by John Mulumba Waswa and Rose Nankya was prepared for interviewing 60 farmers in each of the three sites where beans are the target crop (Nakaseke, Kabwohe, and Rubaya). The team is composed of farmers that are directly involved in the project and were trained to conduct the interviews. The [...]
