indirect and direct human-induced effects on terrestrial carbon (C) sinks and sources. The attribution of C flux quantities to their underlying drivers is a prerequisite to understanding the influence of the terrestrial biosphere on future atmospheric CO2 growth, and the C fluxes that.
Human-induced changes in carbon fluxes across the land-ocean interface can influence the global carbon cycle, yet the impacts of rapid urbanization and establishment of wastewater treatment plants. Telecoupled natural-human systems are analyzed within an economy-wide framework.
• Each driver’s contributions to soy trade, land use and carbon fluxes are quantified. • China’s macroeconomic growth played the most important role in global soybean boom. Direct and indirect human contributions to terrestrial carbon fluxes book Crop productivity growth in Brazil contributed to its cropland expansion.
•Cited by: The capacity to partition natural, indirect, and direct human-induced effects on terrestrial carbon (C) sources and sinks is necessary to be able to predict future terrestrial C dynamics and thus their influence on atmospheric CO 2 growth.
However, it will take a number of years before we can better attribute quantitative estimates of the contribution of various C processes to the net C by: The capacity to partition natural, indirect, and direct human-induced effects on terrestrial carbon (C) sources and sinks is necessary to be able to predict future terrestrial C dynamics and thus.
Weixin Cheng, Alexander Gershenson, in The Rhizosphere, Publisher Summary. This chapter discusses carbon fluxes in the rhizosphere. Terrestrial ecosystems are intimately connected to atmospheric CO 2 levels through photosynthetic fixation of CO 2, sequestration of C in biomass and soils, and the subsequent release of CO 2 through respiration and decomposition of organic matter.

A synthesis of the available literature suggests that human Cited by: Effects of aerosol-induced radiation perturbation and hydrometeorological feedbacks on CO 2 concentrations are investigated. Current aerosol loading is estimated to enhance annual terrestrial carbon sink by Pg C yr −1 (21%) over China.
Aerosols reduce summer CO 2 concentrations by ppm, with the largest reduction being above 2 ppm. Diffuse fraction increment is the dominant Author: Xiaodong Xie, Tijian Wang, Xu Yue, Shu Li, Bingliang Zhuang, Minghuai Wang.
A New Approach for Satellite Monitoring of Pan-Arctic Terrestrial CO2 Exchange. We are developing a new satellite-based approach for regional assessment and monitoring of terrestrial net carbon exchange (NEE) for the pan-Arctic; NEE quantifies the magnitude and direction of land-atmosphere net CO2 exchange and is a fundamental measure of the balance between carbon uptake by vegetation net.

Some researchers claim that this is due to climate by: between direct and indirect effects of human activity on car-bon stocks.

Fluxes of Carbon. The global net flux of carbon from LULCC increased from about Pg C yr −1 in to a peak of nearly Pg C yr −1 in the s (and a spike of Pg C yr −1 in36% of which was from burning of Southeast Asia peatlands) before declining to ~ Pg C yr −1 during last 10 years, – (Figure 3).Cited by: Here we use a process-based model of the terrestrial biosphere 4,5 to evaluate the overall impact of anthropogenic nitrogen inputs on terrestrial ecosystem carbon and nitrous oxide fluxes Cited by: Baseline Carbon Storage, Carbon.

Introduction. There is a rising call to shift the focus of conservation from protecting single species to a broader focus on protecting species as members of biotic communities and ecosystems (Ray et al.Soule et al.Dobson et al.Sinclair and ByromEstes et al.
).This call stems from the recognition that species are functionally interdependent through direct and Cited by:
