An increasing ecological awareness and greater efforts on a global scale to reverse processes of environmental degradation give rise to new forms of social and economic conflict-a "politics of resource stabilization"-which political ecology theorists have yet to fully explore. Blaikie and Brookfield (1987) argue that the long-term payback period of capital-intensive and natural reclamation proc...

Greenhouse gas emissions from the agricultural ecosystem account for 7%–20% of the world’s total greenhouse gas emissions, while approximately 17% of China’s carbon emissions are from agriculture. In this study, based on the scientific calculation system of carbon emissions in agriculture, we calculated the carbon emissions of agriculture in the Hotan prefecture between 1999 and 2013 and analyz...

I develop a reform evaluation method for evaluating labor supply in nonlinear budget sets which is both structural and quasi-experimental. The model only requires preferences to be convex on the budget frontier and results in a simple three-dimensional labor supply function. The estimation exploits only the between-individual variation provided by tax reforms. I apply the method to evaluate ear...

Temperature changes occur in nature faster than other stressors. Plants due to inability to move and change their position, are exposed to extensive variations in daily or seasonal temperature, and therefore, should quickly and effectively adapt to temperature stress. In order to study the effects of heat stress on physiological traits of forage maize hybrids, a factorial split plot experiment ...
