Innovative haricot beans (Phaseolus vulgaris) seed system for smallholder farmers in Dale District, Southern Ethiopia: Experiences from IPMS by Yilma, Y., Berhe, Kahsay, Hoekstra, Dirk, Jaleta, Moti, Alemayehu, F., Gebrehawariat, K., Ayele, D.

“…The problem is furthermore aggravated by the fact that farmers in the southern region do not keep or preserve seed stock until the next season due to the vulnerability of haricot bean seed to storage pests. The project partners introduced/tested various interventions including variety testing, seed multiplication and market linkages using different approaches and tools. …”

Climate change and forest genetic resources - state of knowledge, risks, and opportunities by Loo J, Fady, B., Dawson, I., Vinceti, B., Baldinelli, G.

“…Adapting to climate change poses a greater problem for naturally regenerating populations where the potential for natural migration is hindered by forest fragmentation and agricultural expansion, and when confounding factors for adaption include pests and diseases, reduced population sizes, and simplified forest structures and species compositions. …”

Using climate information to support crop breeding decisions and adaptation in agriculture by Faloon, P, Bebber, D, Bushell, M, Challinor, Andrew J., Dessai, S., Gurr, S, Köhler, Ann-Kristin

“…Population growth in the next few decades will increase the need for food production, while the yields of major food crops could be impacted by the changing climate and changing threats from pests and pathogens. Crop breeding, both through conventional techniques, and GM assisted breeding could help meet these challenges, if adequately supported by appropriate information on the future climate. …”

Determinants of adoption of improved box hive in Atsbi Wemberta District of Eastern Zone, Tigray Region by Abebe, W.

“…Ranking revealed that drought; honeybee pests and disease; lack of beekeeping materials; death of colony; lack of extension support; marketing problem; shortage of bee forage; lack of beekeeping skill and reduction of honeybee colonies were found to be the major constraints in the beekeeping development of the district in their order of importance. …”

Honeybee production and marketing systems, constraints and opportunities in Burie District of Amhara Region, Ethiopia by Belie, T.

“…Data were collected from 120 beekeepers having three types of hives and living in three different agro-ecologies using single-visit-multiple-subject formal survey. The major pests and predators are ants, wax moth (Galleria mellonella), bee lice (Braula coecal), beetles (Aethina tumida), spiders, wasps, prey mantis, lizard, snake, birds and honey badger (Mellivora capensis). …”

DNA barcodes for pathogens of African food crops by Kumar, L., Sharma, K.

“…Studies were conducted to characterize pathogen populations and recognize unique stretches of sequences, known as DNA barcodes, that can be used as genetic markers for the rapid diagnosis of the pathogens and pests affecting the African food crops. The fungal pathogen causing anthracnose (Glomerella cingulata), the most destructive disease of yam and cassava in West Africa, were characterized. …”

Closing the cassava yield gap: an analysis from smallholder farms in East Africa by Fermont, A.M., Asten, Piet J.A. van, Tittonell, Pablo A., Wijk, Mark T. van, Giller, Kenneth E.

“…Poor soil fertility, early water stress and sub-optimal weed management limited cassava production by 6.7, 5.4 and 5.0 t ha−1, respectively, when improved crop establishment and genotypes were used. Pests and diseases were relatively unimportant, while weed management was particularly important in farmer fields during a dry year in Kenya (yield gap of 11.6 t ha−1). …”

Introduction and evaluation of improved varieties of Dioscorea rotundata, and D. cayenensis with high micronutrient content in Cameroon by Njukwe, E., Amah, D., Ndango, R., Tenkouano, A., Asiedu, Robert

“…Production is constrained by several factors including the limited availability and cost of planting material, as well as susceptibility to a range of pests and diseases that cause considerable pre- and post- harvest losses, translated into low yields and poor quality of tubers during storage. …”

Baseline study for impact assessment of high quality insect resistant cowpea in West Africa by Coulibaly, O., Aitchedji, C.C., Gbegbelegbe, Sika, Mignouna, H., Lowenberg-Deboer, J.

“…Grown on more than 12.5 million hectares, grain yields from improved varieties are higher than local varieties, but require 2 to 3 insecticide sprays to control major pests compared to local varieties. Losses due to Maruca alone reach 80% and so far resistance to Maruca has been limited. …”
