Special Issue Information

Dear Colleagues,

Agricultural ecosystems are fundamental to global food security and play a complex role in Earth’s biogeochemical cycles. They act as both a source and a sink for atmospheric carbon dioxide (CO2), and practices for their management significantly influence regional water, energy, and climate balance. Cropping system, irrigation practice, soil health, phenological stage, and extreme weather events all impact the capacity of agroecosystems for carbon sequestration, coping with greenhouse gas emissions, and climate change adaptation and mitigation. This Special Issue aims to advance our understanding of the interactions between agricultural ecosystems and the atmosphere, as well as agriculture’s level of resilience to a changing climate. We welcome original research articles and reviews on the interactions between agricultural ecosystems and the atmosphere, including, but not limited to, crop productivity, evapotranspiration, agricultural greenhouse gas emissions, land use change, and agroecology, as well as their spatial and temporal variation.

We look forward to receiving your contributions to this Special Issue.

Vegetation physiological processes are critical regulators of terrestrial carbon–water cycles and local microclimate dynamics, with photosynthetically active radiation (PAR, 400–700 nm) serving as a primary driving force. However, most vegetation–climate process models simplify the fraction of PAR in global solar radiation as a constant 50%, potentially introducing diurnal simulation biases that propagate into cumulative annual errors in vegetation carbon–water coupling estimates. To address this limitation, we first evaluated the performance of three empirical models for simulating the dynamic PAR fraction and integrated the most accurate model into the Vegetation Microclimate Process (VMcP) model, and further used typical meteorological year (TMY) data of Beijing, Shanghai and Shenzhen as input to compare the differences in vegetation carbon–water processes before and after the improvement. The results show that the diurnal variation range of PAR fraction in global solar radiation is between 39% and 58%. The existing models that neglect the dynamic changes in PAR may overestimate vegetation transpiration cooling and photosynthetic carbon sequestration by 2.3% and 3.5%, respectively. Meanwhile, Shenzhen (64.3 W/m2; 1.59 g/m2·d), characterized by favorable light and thermal conditions, is more prone to large errors compared with Shanghai (47.6 W/m2; 1.21 g/m2·d) and Beijing (39.5 W/m2; 0.93 g/m2·d). This study provides a novel tool for the accurate assessment of vegetation-mediated microclimate improvement, and offers a new perspective for nature-based climate solutions. Full article

As a critical agroforestry crop in Southern China, Moso bamboo, maintains regional timber security and bamboo shoot production, with its net ecosystem productivity (NEP) directly determining dry matter accumulation and economic yield. This study integrates 2024 continuous flux observations with XGBoost and SHAP explanations to characterize the subtropical bamboo forest carbon budget and its nonlinear driving mechanisms. The results show a weak carbon sink in 2024 with an annual cumulative NEP of 120 g C m−2, as high respiration of 860 g C m−2 limited organic matter conversion by consuming nearly 88% of the 980 g C m−2 total primary production. The peak production period during May and June was offset by growth stagnation in August, caused by extreme heat and drought. Net radiation served as the primary driver, with a positive contribution threshold of 75.28 W m−2, whereas precipitation exceeding 1.85 mm or air temperatures over 17.85 °C hindered carbon accumulation through radiation attenuation and metabolic heat loss. Strong radiation–precipitation interactions confirm that water’s impacts on yield are deeply contingent upon radiation backgrounds. These nonlinear regulatory pathways provide a scientific foundation for stabilizing bamboo forest productivity through synergistic water-radiation management and structural optimization during extreme climate events.
