Droughts can have a severe impact on the dynamics of animal populations, particularly in semi-arid and arid environments where herbivore populations are strongly limited by resource availability. Increased drought intensity under projected climate change scenarios can be expected to reduce the viability of such populations, yet this impact has seldom been quantified. In this study, we aim to fi...

In West Africa, the most extreme predicted effects of climate change are expected to occur in desert and grassland areas. It is crucial for local populations in this region to better understand what such projections signify to them to identify sound adaptation policies and interventions. We developed a game, called the “grazing game,” and conducted trials with local farmers at multiple study si...

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 ...

The impacts of climate change on forest community composition are still not well known. Although directional trends in climate change and community composition change were reported in recent years, further quantitative analyses are urgently needed. Previous studies focused on measuring population growth rates in a single time period, neglecting the development of the populations. Here we aimed ...

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...
