How “visible” is urban agriculture in Cameroon? Mapping urban agriculture practices by satellite imagery and field surveys

open access: yesCanadian Geographies / Géographies canadiennes, Volume 70, Issue 3, Autumn / automne 2026.
Abstract Urban agriculture (UA), although promoted in numerous sustainability agendas, has been ignored in public policies of many African countries. This study evaluates the effectiveness of interviews and mapping techniques for characterizing UA and facilitating informed decision making at the local level.

Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1155-1171, May 2026.
Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...

Changing Aerodynamic Roughness in WRF Reduces Bias and Improves Accuracy in Near‐Surface Wind Simulations

open access: yesGeophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Accurate simulation of near‐surface wind speed is crucial for applications in renewable energy, dust emission, and air quality modeling. However, the Weather Research and Forecasting (WRF) model systematically over‐estimates 10 m wind speed due to simplified representations of surface roughness and momentum exchange.

Time to burn: landscape drivers of fuel trait variability and fire regime in savanna ecosystems

open access: yesOikos, Volume 2026, Issue 3, March 2026.
Fuel traits are important determinants of fire behavior and regime in savannas and, thus, of how fire affects plant communities. However, whether these traits are correlated, predictable and how they are influenced by biotic and abiotic drivers remain to be rigorously evaluated.
