| Although it is common to alternate between till and no-till practices, past research has considered farmers’ tillage options to be limited to the dichotomous choice of whether or not to switch to a long-term no-till regime. This paper expands farmers’ options and models their choices of tillage frequency. Less frequent tilling sequesters more carbon but permits a greater accumulation of weeds, whereas more frequent tilling eliminates weeds but releases carbon (tillage emissions). The timing of tillage balances its marginal benefits and costs. Higher payments from industry or government for atmospheric greenhouse gas reductions will increase marginal cost and reduce tillage frequency. Other key parameters, such as higher rates of tillage emissions or... |

| This paper examines and predicts the effects of climate change and climate extremes on China’s land use conversion and soil carbon sequestration under two alternative climate change scenarios. It intends to investigate the following three questions. 1) How did climate factors affect land-use conversion in China from 1988 to 2000 and what was the relative importance of these factors? 2) How would the predicted future climate change pattern affect land-use choice under alternative climate change scenarios? 3) How would the predicted future climate pattern change the spatial distribution of soil organic carbon in China? The study makes two contributions to the literature. First, it integrates climate change, land use conversion, and soil carbon sequestration... |
