Nutritionally enhanced wheat for food and nutrition security por Velu, Govindan, Michaux, Kristina D., Pfeiffer, Wolfgang H.

“…Future challenges include accelerating and maintaining parallel rates of genetic gain for productivity and Zn traits and reversing the trend of declining nutrients in wheat that has been exacerbated by climate change. Application of modern empirical and analytical technologies and methods in wheat breeding will help to expedite genetic progress, shorten time-to-market, and achieve mainstreaming objectives. …”

Drivers of compositional turnover in narrow‐ranged and widespread dragonflies and damselflies in Africa por Basel, Ashleigh Megan, Simaika, John P., Samways, Michael J., Midgley, Guy F., Latombe, Guillaume, MacFadyen, Sandra, Hui, Cang

“…Our results therefore show that odonate turnover is largely driven by climate, although the limited dispersal capabilities of damselflies also influences community assembly. Climate change could cause major changes in composition of odonates, presenting a challenge for conservation planning in Africa as species assemblages that were previously conserved may no longer be protected if their ranges shift outside protected areas. …”

A systematic scoping review of irrigation development and agricultural water management in South Africa por Mabhaudhi, T., Dirwai, Tinashe Lindel, Taguta, C., Kanda, E. K., Nhamo, L., Cofie, Olufunke O.

“…Approximately 90% of sub-Saharan Africa’s agriculture is rain-fed, and the bulk of the farmers are classified as smallholder farmers, constituting 70% of the continent’s population. Climate change (CC) and climate variability (CV) have increasingly imposed yield penalties on Africa’s irrigated and non-irrigated farming sectors. …”

Trade-offs and synergies between pastoral activities and ecosystem services: Valuation of carbon emissions mitigation strategies in livestock systems por Florez, Fernando, Louhaichi, Mounir, Yigezu, Yigezu Atnafe, Gonzalez Quintero, Ricardo, Notenbaert, An, Wane, Abdrahmane, Burkart, Stefan

“…While humans, through consumption, put pressure on natural ecosystems, they also develop and introduce policy, institutional, and technological innovations, which have the potential to improve the carbon balance and mitigate climate change. While there is evidence for the technical efficacy of these interventions, the cost of inaction, the investment required for implementing them, their economic viability, and their impacts if implemented at a large scale have yet to be fully known, thereby limiting our ability to promote financing. …”
