Attribution of the record-breaking extreme precipitation events in July 2021 over central and eastern China to anthropogenic climate change por Wang, L., Gu, X., Slater, L. J., Lai, Y., Zheng, Y., Gong, J., Dembélé, Moctar, Tosunoglu, F., Liu, J., Zhang, X., Kong, D., Li, J.

“…The 2021 EPEs in central (eastern) China occurred in the context of no linear trend (a significantly increasing trend at a rate of 4.44%/decade) in the region-averaged Rx5day (summer maximum 5-day accumulated precipitation) percentage precipitation anomaly (PPA), indicating that global warming might have no impact on the 2021 EPE in central China but might have impacted the 2021 EPE in eastern China by increasing the long-term trend of EPEs. …”

Modeling genotype × environment × management interactions for a sustainable intensification under rainfed wheat cropping system in Morocco por Mamassi, Achraf, Balaghi, Riad, Devkota, Krishna, Bouras, Hamza, El‑Gharous, Mohamed, Tychon, Bernard

“…Under the conditions of Moroccan rainfed agricultural areas, wheat cropping systems—the population’s basic staple food—are subject to a set of limitations that seasonally impact crop production and farmers’ incomes, thus national food security. In the last decades, the major constraints were often related to the country’s Mediterranean-type climate, through the intense recurrence of drought events and high inter- and intra-annual rainfall fluctuations. …”

The input reduction principle of agroecology is wrong when it comes to mineral fertilizer use in sub-Saharan Africa por Falconnier, Gatien N., Cardinael, R., Corbeels, Marc, Baudron, Frederic, Chivenge, Pauline P., Couedel, A., Ripoche, A., Affholder, F., Naudin, K., Benaillon, E., Rusinamhodzi, Leonard, Leroux, L., Vanlauwe, Bernard, Giller, Kenneth E.

“…Proponents of the “yes” answer have put forward the “input reduction” principle of agroecology, i.e. by relying on agrobiodiversity, recycling and better efficiency, agroecological practices such as the use of legumes and manure can increase crop productivity without the need for more mineral fertilizer. We reviewed decades of scientific literature on nutrient balances in SSA, biological nitrogen fixation of tropical legumes, manure production and use in smallholder farming systems, and the environmental impact of mineral fertilizer. …”
