Unravelling vicious circles of land use competition and food insecurity in agropastoral rangelands

People and Nature, EarlyView.
Abstract In many regions of the world, the adoption of new livelihood strategies that compete with traditional strategies is one driver of competition over land, resulting in unforeseen impacts on the livelihoods of land users and accelerating land degradation. One example is the Borana Zone in southern Ethiopia, where the expansion of crop cultivation

Recovering nutrients from urine – A golden opportunity for sustainable fertiliser production

PLANTS, PEOPLE, PLANET, EarlyView.
Agricultural industrialisation has led to levels of nutrients in the environment that are well above safe operating limits, yet fertiliser use is necessary to feed a growing population. The recovery of nutrients from human urine in large, developed cities may offset some of the ecological and economic impacts associated with fertiliser production, as ...

Crop genotypic richness enhances biomass production and phosphorus acquisition in maize‐mycorrhiza symbiosis

PLANTS, PEOPLE, PLANET, EarlyView.
Our study tests how soil and plant biodiversity can enhance sustainability of crop production in Kenya. We tested whether mixtures of maize varieties performed better than monocultures and tested their response to arbuscular mycorrhizal fungi. Mycorrhizal responsiveness differed significantly by maize variety, and genetic mixtures outperformed ...

Conned by the enemy: the entomopathogenic fungus Metarhizium anisopliae lures and kills Drosophila suzukii

Pest Management Science, EarlyView.
Highly pathogenic isolates of Metarhizium anisopliae attracted Drosophila suzukii. Identifying the responsible compounds for this attraction could help the development of these isolates for pest monitoring and overall pest management. Abstract BACKGROUND Drosophila suzukii, commonly known as spotted wing drosophila (SWD), is a highly invasive and ...

Advancing pharmacometrics in Africa—Transition from capacity development toward job creation

CPT: Pharmacometrics &Systems Pharmacology, Volume 14, Issue 3, Page 407-419, March 2025.
Abstract Trained pharmacometricians remain scarce in Africa due to limited training opportunities, lack of a pharmaceutical product development ecosystem, and emigration to high‐income countries. The Applied Pharmacometrics Training (APT) fellowship program was established to address these gaps and specifically foster job creation for talent retention.

On the compatibility of single‐scan terrestrial LiDAR with digital photogrammetry and field inventory metrics of vegetation structure in forest and agroforestry landscapes

Remote Sensing in Ecology and Conservation, EarlyView.
The single‐scan approach to terrestrial laser scanning (TLS) and the self‐terrain‐normalized form of drone‐based digital aerial photogrammetry (DAP) offer practical options for rapid assessment of the vegetation structure in tropical landscapes.
