No-Till Soil Organic Carbon Sequestration Patterns as Affected by Climate and Soil Erosion in the Arable Land of Mediterranean Europe
2022
No-tillage (NT) has been considered an agronomic tool to sequester soil organic carbon (SOC) and match the 4p1000 initiative requirements of conservative soil management. Recently, some doubts have emerged about the NT effect on SOC sequestration, often because observations and experimental data vary widely depending on climate and geographic characteristics. Therefore, a suitable SOC accounting method is needed that considers climate and morphology interactions. In this study, the yearly ratio between SOC in NT and conventional tillage (CT) (RRNT/CT) collected in a previous study for flat (96 samples) and sloping (44 samples) paired sites was used to map the overestimation of SOC sequestra…
Opening the black box of accounting for Greenhouse Gas Emissions: The different views of institutional bodies and firms
2018
Abstract This paper highlights the current accounting approaches to greenhouse gas (GHG) emissions. In particular, it explores and critically discusses the treatment of emission rights (ER) under carbon trading schemes from two distinct angles. On the one hand, it reviews the domestic solutions adopted by accounting bodies and, on the other, it examines current practices followed by firms in the European Energy Exchange (EEX). Regarding the former group, there are substantial differences, which would suggest some potential difficulties in finding a common solution for the future. Not surprisingly, there is still a diversity of approaches with regard to how firms report ER. Although the most…
The carbon count of 2000 years of rice cultivation.
2013
More than 50% of the world's population feeds on rice. Soils used for rice production are mostly managed under submerged conditions (paddy soils). This management, which favors carbon sequestration, potentially decouples surface from subsurface carbon cycling. The objective of this study was to elucidate the long-term rates of carbon accrual in surface and subsurface soil horizons relative to those of soils under nonpaddy management. We assessed changes in total soil organic as well as of inorganic carbon stocks along a 2000-year chronosequence of soils under paddy and adjacent nonpaddy management in the Yangtze delta, China. The initial organic carbon accumulation phase lasts much longer a…
