Climate change and agriculture influence each other. The effects of climate change on agriculture seem to be predominantly negative, although studies show a large variation in impacts between crops and regions. To compensate for these effects, agriculture can either intensify or expand in area; both of these options increase greenhouse gas emissions. It is therefore likely that such negative ef...

agriculture is one of the main sectors affected by climate change. although recently some studies about the nature and size climate change effect on the physical variables of water resources and agriculture have been done, however economic perspectives and the role of adaptation strategies have been less studied empirically. the contribution of this study is modeling real economic behavior of s...

population growth can greatly impact on greenhouse gas emission pattern in the future. considering the importance of population growth in climate change studies, the present research concentrates on the population growth of the middle east in the late 21th century based on the iiasa population scenarios. under the projections of a1-b1 scenario, the world’s population will grow up to 8.7 billion...

The manuscript ‘How will organic carbon stocks in mineral soils evolve under future climate? Global projections using RothC for a range of climate change scenarios’ by Gottschalk et al. describes the outcomes of an extensive modelling approach to predict global soil C stocks by end of this century. The authors used a variety of climate predictions and coupled these scenarios with projections of...

   In this essay, we investigated the effects of climate change on the rivers of selected basins of Guilan province, one of the northern provinces of Iran for the period 2020 to 2050 under three climate scenarios: RCP2.6, RCP4.5, RCP8.5. For this purpose, rainfall and temperature data from 45 climate data stations and 20 hydrometric stations from 1983 to 2013 were used. The average precipitatio...

. introduction global warming and its result, climate change is an important subject investigated especially in the recent decades by researchers throughout the world. in these studies, at first, climatic parameters changes are investigated. considering many uncertainties in the parameters estimation, it is better to choose a method in order to study and analyze the uncertainty band due to diff...

Currently, there is little information on the high mountain species' response to the climate change in Iran, and it seems that these species are significantly affected by the climate change. In the current research, the spatial vulnerability of Caspian snowcock (Tetraogallus caspius) to the  climate change in Chaharmahal and Bakhtiari province was predicted using the ensemble modelling approach...

Predicting the impact of land cover and climate change on hydrologic responses using modeling tools are essential in understanding the movement and pattern of hydrologic processes within the watershed. The paper provided potential implications of land conversions and climate change scenarios on the hydrologic processes of Muleta watershed using soil and water assessment tool model. Model inputs...
