چکیده
The oilseed crop winter camelina (Camelina sativa) is attracting increasing interest for biofuel production. This study assessed the climate impacts of growing as an intermediate in northern Europe (Sweden) production vegetable oil and biofuel. Climate were analyzed using life cycle assessment (LCA), while on biodiversity eutrophication discussed. Three functional units considered: 1 ha land use, kg oil, MJ (hydrogenated HVO). results showed that dry matter yield over whole rotation was higher rotation, despite lower peas due to relay cropping with camelina. In fat more than doubled, protein fiber marginally increased, carbohydrates decreased. Higher related field operations fertilizer use associated N2O emissions, compensated by increased soil carbon accumulation return organic from additional rotation. total impact around 0.5 CO2 eq/kg when macronutrient allocation used. global warming potential 15 g eq/MJ HVO, or 27 HVO effects not included, representing 84% 71% reduction, respectively, compared fossil fuels.

Assessment and analysis of the sensitivity of different methods for estimating of the reference crop evapotranspiration in a cold and moderate climate (Case study: Saqez catchment)
The phenomenon of evapotranspiration causes water and moisture losses from water, soil and vegetation levels. Due to the small amount of atmospheric precipitation and water resource constraints in Iran, it is important to calculate it through a suitable method. The present research attempts to evaluate the evapotranspiration reference crop (ETo) and present it in the form of zoning map as a bas...

Climate change is the main phenomenon that directly affects the world environment, and changes in the environment affect economic sectors differently. The most important impacts of climate change would be on enhancing the average global temperature and the decrease in precipitation. The agricultural sector is the first and most affected sector in the climate change. We examined the impact of te...
