A climate‐sensitive tropical urbanism under extreme heat†

Singapore Journal of Tropical Geography, EarlyView.
Tropical urban dwellers face twin climate challenges that impinge on their quality of life: climate overheating and the urban heat island (UHI). The latter superimposed on the former to lead to high levels of thermal discomfort, carbon and energy consequences.

Microplastic Dynamics in Sediment Layers of Two Ramsar‐Designated Wetlands

Water and Environment Journal, EarlyView.
ABSTRACT Little is known about the vertical and spatial dynamics of microplastics in relation to hydrology and land use, particularly in African context. This study aimed to assess the abundance, type, colour and vertical distribution of microplastics in sediment from two Ramsar‐designated wetlands, the Makuleke and Nylsvley. Sediment core samples were

Global beef production: Trends, challenges, and opportunities for sustainable development

Agricultural &Environmental Letters, Volume 11, Issue 2, December 2026.
Abstract Sustainable livestock systems require managing trade‐offs and synergies across productive, socioeconomic, and environmental dimensions to meet rising global beef demand. We present a biophysical framework to analyze how management‐driven energy allocation is manifested through herd size and total and per‐head beef productivity.

Effects of irrigated cover crop cultivation period on common bean and soybean yield

Crop, Forage &Turfgrass Management, Volume 12, Issue 2, December 2026.
Abstract Cover crop inclusion is essential for improving soil management in tropical no till systems; however, the optimal duration of irrigated off‐season cultivation remains uncertain. This 3‐year field study evaluated nine cover crop species or mixtures and four cultivation periods (60, 75, 90, and 105 days) on biomass production, soil chemical ...

Simulating Agroecology Policy Options for the Resilience of Smallholder Food Security to Climate Shocks

Climate Resilience and Sustainability, Volume 5, Issue 2, December 2026.
Climate shocks and the agroecology–resilience nexus of smallholders. Summary of key findings: Agroecology increases smallholder resilience capacity by 8.7% in the short term under a decreased rainfall scenario, a projected 11% decline in precipitation reduces resilience by 5.6% and 14.2% in the short and long terms, respectively, and a policy‐induced ...
