Recently, global warming problems with rapid population growth and socio-economic development have intensified the demand for water and increased tensions on water supplies. This research evolves the Multi-Objective Coronavirus Optimization Algorithm (MOCVOA) to obtain operational optimum rules of Voshmgir Dam reservoir under the climate change conditions. The climatic variables downscaled and ...

Introduction and Background: The agricultural sector is one of the most important economic sectors due to extensive interaction with the environment, the greatest impact of climate change takes effect.  The agricultural sector affects climate change and affects climate change. Climate change, on the one hand, affects agricultural performance and, on the other hand, affects the price of produ...

Climate change caused the changes in earth surface temperature, precipitation, sea surface level, wind speeds, wave heights, coastlines, etc. Estimation of the effect of climate change is of great importance in long-term studies of such parameters. In this study, the effect of climate change on average wind speed near Chabahar, Gulf of Oman is assessed until the year 2100. For this purpose, win...

■ Abstract Variability of the atmospheric and oceanic circulations in the earth system gives rise to an array of naturally occurring dynamical modes. Instead of being spatially independent or spatially uniform, climate variability in different parts of the globe is orchestrated by one or a combination of several climate modes, and global changes take place with a distinctive spatial pattern res...

climate change around the world is now a reality that has adverse effects on the environment and human health. there is little information about the effect of climate change on food systems, especially seafood from the farm to the table. the aim of this study was to review the fundamental effects of climate change on seafood safety and human health. climate change is expected to increase chemic...

The purpose of this study is to determine and predict the effects of climate change on architecture using climate models. By clarifying the consequences of the impact of urban architecture on climate change while using the data of surrounding stations with library and field data methods. The climatic parameters of precipitation, temperature and relative humidity of the synoptic station of Miyan...

Food fish farming is regarded as one of the most important sectors of the aquaculture industry. Salmon farming is a major contributor to the growth of the aquaculture sector. Climate change is predicted to have a complex impact on aquatic ecosystems, including fisheries and aquaculture. Climate change can cause a fluctuation in water temperature of rivers, lakes, seas, and oceans. This can chan...

Strategies to enhance local adaptation capacity are needed to mitigate climate change impacts and to maintain regional stability of food production. The objectives of this study were to simulate the climate change effects on phenology stages, potato production in the future and to explore the possibilities of employing planting dates and various varieties (Agria, Arinda and Santeh) as mitigatin...
