Collective action for small-scale producers of agricultural biodiversity products por Kruijssen, Froukje, Keizer, Menno, Giuliani, Alessandra

“…This paper explores how the theory of collective action can provide a more synthetic understanding of how market chains operate and how changes in the market chain and market institutions can permit a more equitable distribution of welfare benefits. The case studies illustrate the need for improved trust, a mutual understanding of each actor’s involvement and the need for an agreed process of collective action that involves a high level of community participation to achieve an improved market chain organization benefiting the poor. …”

Agricultural trade liberalization under Doha: the risks facing African countries por Badiane, Ousmane

“…The present discussion paper 1) examines the vulnerability of Africa economies with respect to global agricultural trading policies and their induced changes in world agricultural markets, based on the above characteristics; 2) analyzes the efficiency effects within Africa’s agricultural sector of world market distortions resulting from agricultural trading policies; 3) illustrates the impact of global protectionism on poverty levels and distribution among rural households in Africa and the implication for the objective of poverty reduction; 4) reviews the options and risks facing African countries in their pursuit of opportunities for greater participation in the global trading system, in particular in connection with the Doha trade agenda; and 5) discusses options for global trade liberalization that would best benefit African economies. …”

Global food demand and the contribution of livestock as we enter the new millennium por Delgado, Christopher L., Courbois, Claude, Rosegrant, Mark W.

“…Sensitivity analysis of the impact of restrictions on China’s ability to produce more feedgrains illustrates that in a system of linked global markets for cereals and livestock products, such restrictions are not effective at lowering Chinese livestock consumption, which is driven by global trade in manufactures, although they do lower Chinese livestock production. …”

Unravelling yield and yield-related traits in soybean using GGE biplot and path analysis por Obua, T., Sserumaga, J.P., Tukamuhabwa, P., Namara, M., Awio, B., Mugarra, J., Tusiime, G., Chigeza, G.

“…The findings offer a framework for breeding programs in Uganda and similar agro-ecological regions, promoting more resilient and productive soybean varieties. This study also illustrated the potential advantages of employing more complex mathematical techniques like path analysis to uncover yield and yield-related traits in soybean breeding programs.…”

The effect of climate variability in the efficacy of the entomopathogenic fungus Metarhizium acridum against the desert locust Schistocerca gregaria por Kamga, Samuel F., Ndjomatchoua, Frank T., Guimapi, Ritter A., Klingen, Ingeborg, Tchawoua, Clément, Hjelkrem, Anne-Grete Roer, Thunes, Karl H., Kakmeni, Francois M.

“…Applications of M. acridum against desert locust in a few selected African countries including Morocco, Kenya, Mali, and Mauritania through monthly spatial projection of R0 maps for the prevailing climatic condition are illustrated. By combining mathematical modeling with a geographic information system in a spatiotemporal projection as we do in this study, the field implementation of microbial control against locust in an integrated pest management system may be improved. …”

Salt tolerance in rice: seedling and reproductive stage QTL mapping come of age por Singh, Rakesh Kumar, Kota, Suneetha, Flowers, Timothy J.

“…We have constructed an exhaustive list of the 935 reported QTLs for salinity tolerance in rice at the seedling and reproductive stages. We illustrate the chromosome locations of 63 meta-QTLs (with 95% confidence interval) that indicate the most important genomic regions for salt tolerance in rice. …”

Competitive interactions between weedy rice and cultivated rice as a function of added nitrogen and the level of competition por Chauhan, Bhagirath S., Johnson, David E.

“…In contrast, the PWR and VWR populations under competition produced a greater amount of shoot biomass with each additional unit of N, compared to the IR64 population. The results illustrate that N fertilizer management might affect the outcome of weedy rice competition. …”

Qualification of a plant disease simulation model: performance of the LATEBLIGHT model across a broad range of environments por Andrade-Piedra, Jorge L., Forbes, Gregory A., Shtienberg, Dani, Grünwald, Niklaus J., Chacón, María G., Taipe, Marco V., Hijmans, Robert J., Fry, William E.

“…The concept of model qualification, i.e., discovering the domain over which a validated model may be properly used, was illustrated with LATEBLIGHT, a mathematical model that simulates the effect of weather, host growth and resistance, and fungicide use on asexual development and growth of Phytophthora infestans on potato foliage. …”

Value of quality controlled citizen science data for rainfall-runoff characterization in a rapidly urbanizing catchment por Mengistie, G. K., Wondimagegnehu, Kirubel Demissie, Walker, D. W., Haile, Alemseged Tamiru

“…The citizen science data allowed comparison of runoff coefficient and base flow index for recent and historical periods where recent streamflow data is unavailable from a formal data source. This study illustrates the immense value of (i) multiple data quality assessment steps for building confidence on the quality of citizen science data, and (ii) citizen science for enhancing our understanding of rainfall-runoff relationships and change in a rapidly urbanizing catchment.…”

Decent work in global food value chains: Evidence from Senegal por Fabry, Anna, Van den Broeck, Goedele, Maertens, Miet

“…Results suggest that the agro-industry is inclusive towards migrant, female and young workers, but that discrimination in job quality occurs within and across companies. Results illustrate substantial gender and youth wage gaps, and a lower likelihood of having decent employment among migrant and young workers. …”
