Transformative changes of pastoral livestock production and its consequences on the Qinghai–Xizang Plateau

Grassland Research, Volume 5, Issue 1, Page 35-43, March 2026.
Grassland functional zoning and spatial optimization scheme on the Qinghai–Xizang Plateau. Based on multifunctionality assessment, the scheme proposes allocating 32% of regional grassland as nature reserve grasslands (biodiversity focus), 63% as livestock grazing grasslands (smart ecological–production management), and 5% as cultivated grasslands (high‐

Dramatic Decline in Organic Carbon Burial in Big Estuary Driven by Dam Construction: Insights From the Yellow River Estuary

Earth's Future, Volume 14, Issue 3, March 2026.
Abstract Estuaries and associated shelf deposits, which bury 70%–90% of global marine organic carbon, making them key sites for marine carbon burial. Variations in total organic carbon (TOC) content and the organic carbon burial rate (OCBR) in these sediments strongly influence carbon sequestration dynamics.
