CSIR was commissioned by DME to compile a report on the potential for sequestration of carbon dioxide in South Africa in 2004. This report was the first attempt to obtain a picture of this potential. In the paper the main findings of the 2004 report are summarized. In the introduction the background for the study is presented as well as the main goals of the project. The sources and quantities ...

We develop an integrated model to predict private land-use decisions in response to policy incentives designed to increase the provision of carbon sequestration and species conservation across heterogeneous landscapes. Using data from the Willamette Basin, Oregon, we compare the provision of carbon sequestration and species conservation under five simple policies that offer payments for conserv...

Climate change is one of the most important challenges in sustainable development which has negative effect on terrestrial and aquatic ecosystem. The lead factor of this phenomenon is Co2 accumulation in atmosphere. One of the suitable ways of facing the mentioned issue is carbon sequestration in plant biomass and soil as a simple as well as inexpensive refined way in rangelands. With respect t...

nanocomposites made of carbon nanotube (cnt) bundles have attracted researchers’ attention due to their unusual properties such as: light weight, flexibility and stiffness.  in this paper, the effects of straight and rope-shaped bundles on nanocomposite effective mechanical properties are investigated.  first, fea models are created consisting of cnts with different shapes of straight and rope-...

elevated CO2 (Allen et al., 2000) but no statistically significant differences in fine root production, microbial Soil C sequestration in predicted, future elevated CO2 environbiomass, or plant chemistry. Growth in elevated CO2 ments will be important to atmospheric CO2 levels, soil tilth, and fertility. An elevated CO2 study with ponderosa pines (Pinus poncan lead to changed plant species comp...

This paper analyzes how US presidential candidates should allocate resources across states to maximize the probability of winning the election, by developing and estimating a probabilisticvoting model of political competition under the Electoral College system. Actual campaigns act in close agreement with the model. There is a 0.9 correlation between equilibrium and actual presidential campaign...

Journal: :European Journal of Soil Science 2022

We have read with interest an opinion paper recently published in the European Journal of Soil Science (Berthelin et al., 2022). This presents some interesting considerations, at least one which is already well known to soil scientists working on organic carbon (SOC), that is, a large portion (80%–90%) fresh inputs subject rapid mineralization. The short-term mineralization kinetics well-known ...
