Transitioning From Rice‐Wheat to Diversified Rice‐Based Rotations Enhances Rice Production and Mitigates Greenhouse Gas Emissions Across Asia

open access: yesEarth's Future, Volume 14, Issue 9, September 2026.
Abstract Rice‐wheat cropping systems underpin food security across Asia but also represent major sources of agricultural greenhouse gas (GHG) emissions. Replacing wheat with diversified crop species to create alternative rice‐based cropping systems may become an effective strategy for sustainable production.

Coastal Nitrogen, Phosphorus, and Silicon Sources: Integrating Land, Sea, and Human Inputs

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 9, September 2026.
Abstract Land‐based human activities have greatly increased inputs of nutrients (nitrogen [N] and phosphorus [P]) to the coastal zone, while also decreasing silicon (Si) export. Here we present a novel synthesis of N, P, and Si sources to coastal waters and use that data set to evaluate: (a) the amount, global spatial distribution, and proportion of N,

Uncovering the Underestimated Greenhouse Gas Emissions of Hydropower Reservoirs: A Global Synthesis

open access: yesGlobal Biogeochemical Cycles, Volume 40, Issue 9, September 2026.
Abstract Hydropower reservoirs, long considered as a clean energy solution, are increasingly recognized as major greenhouse gas (GHG) emissions hotspots. However, over 97% of these hydropower reservoirs remain unmonitored, creating major uncertainties in global GHG budgets.

Low Denitrification, Anammox, and Dissimilatory Nitrate Reduction to Ammonium Rates in a Low Disturbance Mangrove‐Saltmarsh System Using an in Situ Intact Chamber Method

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Mangroves and saltmarshes can remove anthropogenic nitrogen (N) moving from the land to the ocean, but many previous N cycling measurements used destructive sampling procedures that excluded important habitats such as crab burrows, pneumatophores, and saltmarsh vegetation.

Top‐Down and Bottom‐Up Drivers of Soil δ15N Spatial Patterns in a Tropical Savanna

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 9, September 2026.
Abstract Although stable nitrogen isotopes (δ15N) can provide a powerful integrative tracer of localized nutrient cycling across heterogeneous savannas, the relative influence of top‐down versus bottom‐up drivers in shaping these spatial patterns remains largely unresolved.
