Informal value chain actors’ knowledge and perceptions about zoonotic diseases and biosecurity in Kenya and the importance for food safety and public health por Nyokabi, S., Birner, Regina, Bett, Bernard K., Isuyi, L., Grace, Delia, Güttler, D., Lindahl, Johanna F.

“…There was a gendered dimension, evidenced by markedly different participation in value chains and lower adoption rates and knowledge levels among female actors. Finally, cultural and religious practices were shown to play an important role in exposure and transmission of diseases, influencing perceptions and attitudes to risks and adoption of biosecurity measures.…”

Genetic differentiation analysis of African cassava (Manihot esculenta) landraces and elite germplasm using amplified fragment length polymorphism and simple sequence repeat marker... por Raji, A.A.J., Fawole, I., Gedil, Melaku A, Dixon, Alfred G.O.

“…Within-population diversity estimates obtained with both markerswere correlated, showing little variation in their fixation index. The amountof within-population variation was higher for landraces as illustrated by bothmarkers, allowing discrimination among accessions along their geographicalorigins, with some overlap indicating the pattern of germplasm movementbetween countries. …”

The geography of large-scale land acquisitions: Analysing socio-ecological patterns of target contexts in the global South por Messerli, P, Giger, M, Dwyer, M.B., Breu, T., Eckert, S.

“…Improving and enhancing large datasets of georeferenced land deals is an important next step; at the same time, careful choice of the spatial scale of analysis is crucial for ensuring compatibility between the spatial accuracy of land deal locations and the resolution of available geospatial data layers. Finally, we argue that new approaches and methods must be developed to empirically link socio-ecological patterns in target contexts to key determinants of land investment processes. …”

Characterizing Forest Change Using Community-Based Monitoring Data and Landsat Time Series por Vries, B. de, Pratihast, A.K., Verbesselt, Jan, Kooistra, L., Herold, Martin

“…By dividing the local expert data into training and operational phases corresponding to local monitoring activities, we found that forest change models improved as more local expert data were used. Finally, we produced maps of deforestation and degradation using the most important spectral bands. …”

Genetic diversity and population structure of Urochloa grass accessions from Tanzania using simple sequence repeat (SSR) markers por Kuwi, S.O., Kyallo, Martina M., Mutai Collins, K., Mwilawa, A., Hanson, Jean, Djikeng, Appolinaire, Ghimire, Sita R.

“…The analysis of molecular variance revealed high genetic variation within individual accessions in a species (92%), fixation index of 0.05 and gene flow estimate of 4.77 showed a low genetic differentiation and a high level of gene flow among populations. …”

Roots, Tubers and Bananas Contributions to Food Security Article por Kennedy, Gina, Raneri, Jessica Evelyn, Stoian, Dietmar, Attwood, Simon, Burgos, G., Ceballos, Hernán, Ekesa, Beatrice, Johnson, Vincent, Low, Jan W., Talsma, Elise F.

“…The impact of changing climate on resistance to disease/pest threats as well as yield and longer-term sustainability issues is also of concern. Finally, greater research and development on propagation and post-harvest storage and processing is needed for some of the lesser RTB crops.…”

Understanding the economic impact of BXW and its management practices in East and Central Africa por Cori, V. di, Kikulwe, Enoch Mutebi, Kozicka, M., Gotor, Elisabetta

“…Further, we review determinants of adoption of the BXW management practices and finally relate them to the estimates of costs of inaction (losses due to BXW spread). …”

Impact of climate change on future rice production in the Mekong River Delta por Nguyen Huu Quyen, Trinh Hoang Duong, Bui Tan Yen, Sebastian, Leocadio S.

“…The estimated rice yield was then deducted for the projected El Niño and La Niña years based on yield reduction ratios obtained from analyses of historical yield and climate data. Finally, seasonal rice production of provinces was calculated based on the estimated yield and the climate-related risk maps. …”

Copper induces a viable but nonculturable (VBNC) state in Erwinia amylovora por Ordax, Mónica, Marco-Noales, Ester, López, María M., Biosca, Elena G.

“…Dilution studies were also performed to demonstrate that the resuscitated cells came from a true resuscitation and not from the regrowth of any undetectable culturable cell. Finally, the pathogenicity of both VBNC and resuscitated cells was evaluated by inoculation on immature pear fruits. …”

Salt tolerance in Lycopersicon species .4. Efficiency of marker-assisted selection for salt tolerance improvement por Monforte, Antonio J., Asins, María J., Carbonell, Emilio A.

“…While F-3 variation was mainly due to the within-family component, in the F-4 the FN and FW between-family component was larger than the within-family one, indicating an efficient compartmentalization and fixation of QTLs into the F-4 families. Comparison of the yield of these families under control versus saline conditions showed that fruit weight is a key trait to success in tomato salt-tolerance improvement using wild Lycopersicon germplasm. …”
