Farm level analysis of smallholder farmers implementing Sustainable Intensification technologies in Malawi por Cossu, Alessandra

“…This analysis also highlighted what previous studies already acknowledged: smallholder farmers are highly heterogeneous in their farm characteristics and endowments and if such variables are considered together with the local bio-physical conditions then it becomes clear that such technologies must be adapted to specific agroecological zones by supporting farmers in their decision process.…”

Evaluating the use of nitrogen and phosphorous fertilization as crop management options for maize adaptation to climate change in the Nigeria savannas por Tofa, A., Kamara, A., Babaji, B.A., Adnan, A.A., Ademulegun, T., Bebeley, J.F.

“…In this study, the already calibrated and validated CERES-maize model in DSSAT was used to simulate the response of maize varieties to N and P in three agroecological zones. Similarly, the model, coupled with data for representative concentration pathways (RCP4.5 and RCP8.5) scenarios, was applied to simulate maize yields for mid-century and end-of-century periods and to estimate the effect of use of N and P as a strategy for maize adaptation to climate change. …”

Landscape genomics reveals regions associated with adaptive phenotypic and genetic variation in Ethiopian indigenous chickens por Getachew, Fasil, Derks, M.F.L., Dessie, Tadelle, Hanotte, Olivier H., Barros, C.P., Crooijmans, R.P.M.A., Komen, H., Bastiaansen, J.W.M.

“…Average genetic differences measured by are low between gradients, but XP-EHH signals are the strongest between agroecologies. Genes in the calcium signalling pathway, those associated with the hypoxia-inducible factor (HIF) transcription factors, and sports performance (GALNTL6) are under selection in high-altitude populations. …”

Are the metrics that companies use effective for monitoring supply chain sustainability? A closer look at cocoa and rice por Jones, Sarah, Sanchez, Andrea, Wickramaratne, Chaturangi, Waakabu, Dirisa, Ivanova, Yovita, Thai, Minh, Mockshell, Jonathan, Sanchez Choy Sanchez, Jose, Steinke, Jonathan

“…It also creates a risk that certain locally important negative impacts (e.g. water depletion, soil degradation, forced labour, and farmer debt-levels) are under-reported, and that the indicators in use are poorly suited to the agroecological, multifunctional farms of the future (e.g. yield measured in tons/ha is a metric well-suited to monocultures and not to agroforestry systems, where whole system yields should be captured).…”
