African Twist of Circular Economy: Insights, Policies and Recommendations

Business Strategy and the Environment, EarlyView.
ABSTRACT While the circular economy (CE) has gained traction, this paper argues that mainstream CE approaches risk being misaligned in the African context. Drawing on a mixed‐methods synthesis of empirical studies, policy documents and cross‐country examples, the study shows that Africa's CE transition is fragmented and uneven, leaving the continent at

Generating Helical Polymorphic Beams Using Dielectric Metasurfaces

Laser &Photonics Reviews, EarlyView.
Helix‐shaped polymorphic beams are optical fields whose intensity maxima spiral around the propagation axis, enabling particle manipulation through attractive or repulsive forces. Traditionally requiring expensive spatial light modulators, metasurfaces now provide a compact, cost‐effective alternative. This work demonstrates general helical polymorphic

Machine Learning-Based Real-Time Axle Torque Prediction Model for Electric Tractors Using Field-Measured Data

Agriculture
Accurate estimation of axle torque is essential for performance evaluation and energy management of electric tractors. However, direct torque measurement and access to motor controller data are often limited in commercial platforms. This study proposes a

Human–wildlife coexistence and social context: Evidence from farmer communities in southern Sri Lanka

People and Nature, EarlyView.
Abstract Studies on human–wildlife interactions (HWI) often focus on conflict mitigation studies, thus overlooking underlying factors that influence community decisions to coexist with wildlife. To address this knowledge gap, we collected empirical evidence of how community interactions with wildlife are shaped by their social contexts.

Innovation in pest management: can the past inform the future?

Pest Management Science, EarlyView.
Progress in pest management occurred incrementally, but occasionally, transformative discoveries introduced disruptive technologies. Looking ahead, generative artificial intelligence is expected to accelerate agricultural discovery by integrating vast datasets from mechanization, genetics, and chemistry.
