Unequal Land and Water Changes Between Nations Driven by International Boundary Rivers: Mapping and Temporal Analysis of Shared Borders Between China and Its Neighbors

Earth's Future, Volume 14, Issue 4, April 2026.
Abstract International Boundary Rivers (IBRs), as natural political frontiers, constitute one‐third of China's land borders. However, a lack of systematic monitoring has led to a limited understanding of the distribution of these politically significant rivers and the potential risks posed by their dynamic nature.

A light-weight model to generate NDWI from Sentinel-1

The use of Sentinel-2 images to compute Normalized Difference Water Index (NDWI) has many applications, including water body area detection. However, cloud cover poses significant challenges in this regard, which hampers the effectiveness of Sentinel-2 images in this context.

Towards Affordable Wetland Evapotranspiration Monitoring Using the Variance‐Bowen Ratio Method: Insights From Three Contrasting Wetlands

Water Resources Research, Volume 62, Issue 4, April 2026.
Abstract Accurate measurement of evapotranspiration (ET) is essential for sustainable water management. Standard methods such as eddy covariance (EC) are costly, while alternatives such as surface renewal are cheaper but require calibration and complex data processing.

Should you use data integration for your distribution model?

Journal of Animal Ecology, Volume 95, Issue 4, Page 591-604, April 2026.
This paper explores cases where data integration (the joint modelling of two or more observational datasets) is useful for species distribution models, and also highlights cases where it's actually not useful. This provides the first concrete guidance for deciding whether or not data integration is worth your time.
