Cashing in on climate change : political theory and global emissions trading [PDF]

open access: yes, 2011
Global climate change raises profound questions for social and political theorists. The human impacts of climate change are sufficiently broad, and generally adverse, to threaten the rights and freedoms of existing and future members of all countries ...

Returning Tea Pruning Residue and Its Biochar Had a Contrasting Effect on Soil N2O and CO2 Emissions from Tea Plantation Soil

open access: yesAtmosphere, 2018
A laboratory incubation experiment is conducted for 90 days under controlled conditions where either pruning residue or its biochar is applied to determine which application generates the lowest amount of greenhouse gas from tea plantation soil. To study

Unified models of molecular emission from Class 0 protostellar outflow sources [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2013
Low-mass star-forming regions are more complex than the simple spherically symmetric approximation that is often assumed. We apply a more realistic infall/outflow physical model to molecular/continuum observations of three late Class 0 protostellar sources with the aims of (a) proving the applicability of a single physical model for all three sources ...

Soil Bacteria Mediate Soil Organic Carbon Sequestration under Different Tillage and Straw Management in Rice-Wheat Cropping Systems

open access: yesAgriculture, 2022
Soil organic carbon (SOC) largely influences soil quality and sustainability. The effects of no-till (NT) and crop straw return practices (SR) on soil organic carbon sequestration have been well documented.

Soil Nitrous Oxide Emissions Following Crop Residues Management in Corn-Wheat Rotation Under Conventional and No-Tillage Systems

open access: yesAir, Soil and Water Research, 2022
Agricultural activity is the major anthropogenic source of nitrous oxide (N 2 O) emissions from terrestrial ecosystems. Conservation agriculture including crop residue management can play a key role in enhancing soil resilience to climate change and ...
