Exploring basin scale salinity problems using a simplified water accounting model: the example of Zayandeh Rud Basin, Iran por Droogers, Peter, Salemi, H.R., Mamanpoush, A.R.

“…However, if salinity levels are not to exceed 2 dS m-1, mean annual water release requirements from the reservoir will increase from 52 to 64 m3 s-1, and peak requirements during the irrigation season will increase from 85 to 112 m3 s-1. Finally, it was concluded that the methodology and the model developed were useful for a swift and transparent analysis of past, current and future water and salt resources, and to perform scenario analyses.…”

Genetic diversity, inter-gene pool introgression and nutritional quality of common beans (Phaseolus vulgaris L.) from Central Africa por Blair, Matthew W., González Martínez, L.F., Kimani, P.M., Butare, L.

“…Observed heterozygosity was also high and may be explained by the common practice of maintaining seed and plant mixtures, a coping strategy practiced by Central African farmers to reduce the effects of abiotic and biotic stresses. Finally, nutritional quality differed between the gene pools with respect to seed iron and zinc concentration, while genotypes from the intermediate group were notably high in both minerals. …”

A simplified cost-effective method for area-wide testing of trypanocidal drug sensitivity of T. congolense in mice por Geerts, S., Ndung'u, J.M., Murilla, G., Mbwambo, H., Sinyangwe, L., Machila, N., Delespaux, V., Brandt, J., Peregrine, A.S., McDermott, John J., Holmes, P.H., Eisler, M.C.

“…The method showed clear differences in the level of drug sensitivity of T congolense populations from different areas of Kenya, Tanzania, and Zambia. Finally, an even more simplified protocol was developed on the basis of results obtained with the three-dose protocol, using just a single dose of each drug; 1.0 mg/kg b.w. for isometamidium, and 20 mg/kg b.w. for diminazene. …”

Where to Target Conservation Agriculture for African Smallholders? How to Overcome Challenges Associated with its Implementation? Experience from Eastern and Southern Africa por Baudron, Frédéric, Thierfelder, Christian L., Nyagumbo, Isaiah, Gerard, Bruno G.

“…We argue that most of these performance challenges can (and should) be addressed by agronomic and socio-economic research, and provide four examples where the International Maize and Wheat Improvement Center (CIMMYT) and its partners have been successfully alleviating four very different challenges through research and development (R&D) in Eastern and Southern Africa. Finally, we describe an iterative and multi-scale R&D approach currently used by CIMMYT in Eastern and Southern Africa to overcome challenges associated with the implementation of CA by African smallholders. …”
