Matched topics: drought

Abstract Plants encounter various abiotic stresses under field conditions. Among them, drought stress adversely affects crop productivity and threatens global food security. Drought stress triggers downstream pathways such as phytohormone homeostasis and their signaling pathways. Consequently, this initiates the biosynthesis of different types of protective secondary metabolites (SMs). SMs provide multistress tolerance, including abiotic and biotic stresses. In drought conditions, soil become…

Abstract Gross primary productivity (GPP) is the largest flux in the global terrestrial carbon cycle. Drought has significantly impacted global terrestrial GPP in recent decades, and has been projected to occur with increasing frequency and intensity. However, the drought risk of global terrestrial GPP has not been well investigated. In this study, global terrestrial GPP during 1981–2016 was simulated with the process‐based Boreal Ecosystem Productivity Simulator model. Then, the drought risk…

Matched topics: river, streamflow, drought

Abstract While 1992 marked the first major dam – Manwan – on the main stem of the Mekong River, the post‐2010 era has seen the construction and operationalisation of mega dams such as Xiaowan (started operations in 2010) and Nuozhadu (started operations in 2014) that were much larger than any dams built before. The scale of these projects implies that their operations will likely have significant ecological and hydrological impacts from the Upper Mekong Basin to the Vietnamese Delta and beyon…

Journal: Earth System Dynamics · DOI: 10.5194/esd-12-601-2021 · Citations: 375

Matched topics: earth system model

Abstract. With progressing global warming, there is an increased risk that one or several tipping elements in the climate system might cross a critical threshold, resulting in severe consequences for the global climate, ecosystems and human societies. While the underlying processes are fairly well-understood, it is unclear how their interactions might impact the overall stability of the Earth’s climate system. As of yet, this cannot be fully analysed with state-of-the-art Earth system models …

Dryland vegetation productivity is strongly modulated by water availability. As precipitation patterns and variability are altered by climate change, there is a pressing need to better understand vegetation responses to precipitation variability in these ecologically fragile regions. Here we present a global analysis of dryland sensitivity to annual precipitation variations using long-term records of normalized difference vegetation index (NDVI). We show that while precipitation explains 66% …

Separating Physics and Dynamics Grids for Improved Computational Efficiency in Spectral Element Earth System Models

Abstract Previous studies have shown that atmospheric models with a spectral element grid can benefit from putting physics calculations on a relatively coarse finite volume grid. Here we demonstrate an alternative high‐order, element‐based mapping approach used to implement a quasi‐equal‐area, finite volume physics grid in E3SM. Unlike similar methods, the new method in E3SM requires topology data purely local to each spectral element, which trivially allows for regional mesh refinement. Simu…

Surge in global metal mining threatens vulnerable ecosystems

Authors: Sebastian Luckeneder, Stefan Giljum, Anke Schaffartzik, Victor Maus, Michael Tost

Journal: Global Environmental Change · DOI: 10.1016/j.gloenvcha.2021.102303 · Citations: 211

Matched topics: water management

Mining activities induce profound changes to societies and the environment they inhabit. With global extraction of metal ores doubling over the past two decades, pressures related to mining have dramatically increased. In this paper, we explore where growing global metal extraction has particularly taken effect. Using fine-grain data, we investigate the spatial and temporal distribution of mining of nine metal ores (bauxite, copper, gold, iron, lead, manganese, nickel, silver and zinc) across…

Matched topics: water management

The availability and use of fresh water are critical for human health and for economic and ecosystem stability. But the growing mismatch between human demands and natural freshwater availability is contributing to water scarcity, affecting industrial and agricultural production and a wide range of social, economic, and political problems, including poverty, deterioration of ecosystem health, and violent conflicts. Understanding and addressing different forms of water scarcity are vital for mo…

Assessment of physicochemical properties of water and their seasonal variation in an urban river in Bangladesh

Large historical carbon emissions from cultivated northern peatlands

Authors: Chunjing Qiu, Philippe Ciais, Dan Zhu, Bertrand Guenet, Shushi Peng, Ana Maria Roxana Petrescu et al.

Journal: Science Advances · DOI: 10.1126/sciadv.abf1332 · Citations: 133

Matched topics: land surface model

However, we lack temporally and spatially explicit estimates of carbon losses from cultivated peatlands. Using a process-based land surface model that explicitly includes representation of peatland processes, we estimate that northern peatlands converted to croplands emitted 72 Pg C over 850-2010, with 45% of this source having occurred before 1750. This source surpassed the carbon accumulation by high-latitude undisturbed peatlands (36 to 47 Pg C). Carbon losses from the cultivation of north…

Quantifying the Stable Water Isotopologue Exchange Between the Snow Surface and Lower Atmosphere by Direct Flux Measurements

Authors: Sonja Wahl, Hans Christian Steen‐Larsen, Joachim Reuder, Maria Hörhold

Journal: Journal of Geophysical Research Atmospheres · DOI: 10.1029/2020jd034400 · Citations: 103

Matched topics: surface water

Abstract Surface processes in high latitudes play an important role in global climate and thus understanding the physics of these systems is critical for improving climate projections. The characterization of the stable water isotopologue flux between the surface and the atmosphere offers the potential to constrain parameterizations of these physical surface exchange processes in numerical models. In addition, observations of isotopologue surface fluxes allow the evaluation of surface fluxes …
