| dc.description.abstract | Climate change has consequences on humans and nature worldwide. In recent years, human activities have increased CO2 concentrations. Increasing emissions of greenhouse gases affects changes in temperature, rainfall and other climatic parameters, which is predicted to have negative consequences on the agricultural system. In other words, climate is one of the most fundamental natural factors and its change is one of the most important challenges of this century. Due to the socio-economic importance of agriculture for food security, it seems necessary to assess risks of climate change on the agricultural system and provide adaptation strategies. but risk management cannot be properly implemented without identifying and evaluation of current risk assessments of climate change. In this thesis, I will try to compare current practice of climate risk assessment in different study samples with contemporary risk science based on inter alia the (A,C,U) scheme. Finally, I thoroughly evaluate a case study and determine the effect of changing climate parameters, i.e. temperature and rainfall, on crop yields and the amount of risk created. | |
