Farmer participatory research in cassava technology transfer in India por Ramanathan, S., Anantharaman, M.

“…The concept and methodology used in the transfer of technology (TOT) have undergone changes over the years corresponding to farmers' needs, and as a result, farmer participatory TOT has become more relevant, especially in complex diversified risk-prone (CDR) farming systems. …”

Quantitative assessment of social and economic impact of African swine fever outbreaks in northern Uganda por Chenais, Erika, Boqvist, Sofia, Emanuelson, Ulf, Brömssen, C. von, Ouma, Emily A., Aliro, T., Masembe, Charles, Ståhl, Karl, Sternberg Lewerin, Susanna

“…The results indicate that causality of social and economic impact of ASF outbreaks in smallholder systems is complex. Pigs are mostly kept as passive investments rather than active working capital, complicating economic analyses and further disqualifying disease control arguments based only on standard economic models.…”

Regulatory considerations surrounding the deployment of Btexpressing cowpea in Africa: report of the deliberations of an expert panel por Huesing, J.E., Romeis, J., Ellstrand, N.C., Raybould, A., Hellmich, R.L., Wolt, J.D., Ehlers, J.D., Dabiré-Binso, L.C., Fatokun, C.A., Hokanson, K.E., Ishiyaku, M.F., Margam, V.M., Obokoh, N., Mignouna, J.D., Nang’ayo, F., Ouédraogo, J.T., Pasquet, R.S., Pittendrigh, Barry Robert, Schall, B.A., Stein, J., Tamo, Manuele, Murdock, L.L.

“…Insect predation – predominately from the legume pod borer (Maruca vitrata), flower thrips (Megalurothrips sjostedti) and a complex of pod-sucking bugs (e.g., Clavigralla spp) – is a major yield-limiting factor in West African cowpea production. …”

A Predictive Model for Time-to-Flowering in the Common Bean Based on QTL and Environmental Variables por Bhakta, Mehul S., Gezan, Salvador A., Clavijo Michelangeli, José A., Carvalho, Melissa, Zhang, Li, Jones, James W., Boote, Kenneth J., Correll, Melanie J., Beaver, James S., Osorno, Juan M., Colbert, Raphael, Rao, Idupulapati M., Beebe, Stephen E., González, Abiezer, Ricaurte Oyola, José Jaumer, Vallejos, C. Eduardo

“…The model provides the means to disentangle the environmental dependencies of complex traits, and presents an opportunity to identify in-silico QTL allele combinations that could yield desired phenotypes under different climatic conditions.…”

Quantitative variation and interrelationship between factors influencing cassava yield por Ntawuruhunga, Pheneas, Dixon, Alfred G.O.

“…Results from multiple regression and path analysis suggested, however, that the model does not fully explain the complex interrelationship of factors determining cassava yield and this will need additional research to understand better yield factors.…”

Pathways from research on improved staple crop germplasm to poverty reduction for smallholder farmers por Alwang, Jeffrey, Gotor, Elisabetta, Thiele, Graham, Hareau, Guy, Chamberlain, J.

“…Innovations to improve staple crop germplasm can reduce poverty and otherwise improve farmer livelihoods through complex and multiple pathways. This paper reviews the evidence for one prominent pathway—through increased incomes (in cash and kind) for poor farmers who adopt the technology. …”

300 years of hydrological records and societal responses to droughts and floods on the Pacific coast of Central America por Guevara Murua, Alvaro, Williams, Caroline A., Hendy, Erica J., Imbach, Pablo

“…The management of hydrological extremes and impacts on society is inadequately understood because of the combination of short-term hydrological records, an equally short-term assessment of societal responses and the complex multi-directional relationships between the two over longer timescales. …”

Systematic evaluation of scenario assessments supporting sustainable integrated natural resources management: evidence from four case studies in Africa por Reinhardt, J., Liersch, S., Abdeladhim, Mohamed Arbi, Diallo, M., Dickens, Chris, Fournet, S., Hattermann, F.F., Kabaseke, C., Muhumuza, M., Mul, Marloes L., Pilz, T., Otto, I.M., Walz, A.

“…The results show that all types of scenario assessments address many sustainability challenges, but that the more complex ones based on story and simulation and model coupling are the most comprehensive. …”

Envisioning REDD+ in a post-Paris era: between evolving expectations and current practice por Turnhout, Esther, Gupta, A.K., Weatherley-Singh, J., Vijge, M.J., Koning, J. de, Visseren-Hamakers, I.J., Herold, Martin, Lederer, M.

“…While there is growing recognition that co‐benefit generation is key, and that piece‐meal, forest‐carbon focused REDD+ interventions are unlikely to address the complex causes of tropical forest loss, forest carbon is still being foregrounded in measuring and reporting on REDD+ performance, and in generating results‐based payments (even as these aspects remain challenging). …”

Agricultural intensification exacerbates spillover effects on soil biogeochemistry in adjacent forest remnants por Didham, R.K., Barker, G.M., Bartlam, S., Deakin, E.L., Denmead, L.H., Flak, L.M., Peters, J.M.R., Tylianakis, Jason M., Wright, H.R., Schipper, L.A.

“…For seven variables, the magnitude of effects scaled significantly with magnitude of surrounding land-use intensity, through complex interactions with fencing and edge effects. …”

Genomic prediction for 25 agronomic and quality traits in alfalfa (Medicago sativa) por Jia, C., Zhao, F., Wang, X., Han Jianlin, Zhao, H., Liu, G., Wang, Z.

“…Genomic prediction based on genotyping-by-sequencing (GBS) data could shorten the breeding cycles and accelerate the genetic gains of these complex traits, if they display moderate to high prediction accuracies. …”

Large genetic diversity for fine-flavor traits unveiled in cacao (Theobroma cacao L.) with special attention to the native Chuncho variety in Cusco, Peru por Eskes, A., Rodríguez, C.A.C., Cruz Condori, D., Seguine, E., García Carrion, L., Lachenaud, P.

“…Stable expression of multi-trait Chuncho sensory profiles suggest pleiotropic dominant inheritance, favoring selection for quality traits, which is contrasting with the complex sensory trait determination in other fleshy fruit species. …”

Pedoenvironments driving the monodominance of Peltogyne gracilipes (Leguminosae) in the Northern Amazon, Brazil por Angulo Villacorta, Carlos Darwin, Da Silva Carvalho, Lidiany Camila, Trindade Nascimiento, Marcelo, Imbrozio Barbosa, Reinaldo

“…Initial research confirmed that P. gracilipes monodominance was associated with higher soil magnesium content, while recent studies have indicated a larger number of variables, suggesting a more complex hydro-edaphic habitat. As such, the present study aimed to describe the hydro-edaphic habitat (pedoenvironment) where P. gracilipes is monodominant. …”
