摘要

The agricultural sector plays a vital role in ensuring food security, but it also significantly contributes to pollution and has been permanently affected by climate change. The agricultural sector in the Haraz-Qarasu basin (Iran) is also affected by this principle, and there is an immediate need to restructure the production network in response to the consequences of climate change. The study presents a pristine multi-objective programming model within the nexus framework that addresses profit maximization with less emissions by considering the consequences of climate change, against the past studies, which have only focused on economic aspects. This research focused on quantifying the temperature and precipitation in the region for the future. The results indicate that the average temperature and precipitation trends in the pessimistic scenario (RCP 8.5) are increasing and decreasing, respectively. The water requirement for growing rice and barley is expected to rise in the future under the pessimistic scenario. The rice yield simulation results suggest a forthcoming 3% decline in yield, followed by a 6% rise in the foreseeable future and a substantial 21% increase in the distant future. During the next stage, a multi-objective mathematical programming model was implemented within the nexus framework. The study introduced a production network simulation scenario, with the main objectives of reducing pollution and maximizing profit, which would lead to a 7.2% decrease in the total cultivated area. Also, there will be a decline of 10.1% in water usage, 8.8% in emissions, and a decrease of 10.1% in profits within the basin, which highlighted the trade-off between the goals. The study investigated the future influence of climate change and claimed that in the pessimistic scenario (RCP 8.5), a substantial decrease of 42.1% in cultivated land is expected and a decrease of 45.2% in pollution between 2041 and 2050. Policies such as increasing irrigation efficiency by using modern technologies, modifying the cultivation pattern to suit the climate features of each region, increasing investment and upgrading infrastructure, promoting agricultural mechanization to minimize waste and boost productivity, and focusing on research and development can help improve conditions.
