Simulating future wheat yield under climate change, carbon dioxide enrichment and technology improvement in Iran. Case study: Azarbaijan region

Estimating climate change, CO2 and technology development effects on wheat yield in northeast Iran.

Wheat is the main food for the majority of Iran's population. Precise estimation of wheat yield change in future is essential for any possible revision of management strategies. The main objective of this study was to evaluate the effects of climate change, CO2 concentration, technology development and their integrated effects on wheat production under future climate change. This study was perf...

Developing Area Yield Crop Insurance under Alternative Parametric Methods: Case study for Wheat in East Azarbaijan Province, Iran

In crop insurance design, the yield guarantee and the premium are very important parameters, both of which depend upon the yield distribution. Accordingly, the accurate modeling of yield distribution is essential for designing crop insurance contracts. This study employs historical county-level yield data for irrigated and dry wheat in East Azarbaijan Province, Iran for 1975-2013 to evaluate th...

Importance of carbon dioxide physiological forcing to future climate change.

An increase in atmospheric carbon dioxide (CO(2)) concentration influences climate both directly through its radiative effect (i.e., trapping longwave radiation) and indirectly through its physiological effect (i.e., reducing transpiration of land plants). Here we compare the climate response to radiative and physiological effects of increased CO(2) using the National Center for Atmospheric Res...

Terrestrial Carbon Cycle Dynamics under Recent and Future Climate Change

The behavior of the terrestrial carbon cycle under historical and future climate change is examined using the University of Victoria Earth System Climate Model, now coupled to a dynamic terrestrial vegetation and global carbon cycle model. When forced by historical emissions of CO2 from fossil fuels and land-use change, the coupled climate–carbon cycle model accurately reproduces historical atm...
