Evaluating and forecasting the changes in habitat quality (HQ) caused by land use/land cover (LULC) variations during urbanization is crucial for establishing a comprehensive ecological planning system and tackling the obstacles to global sustainable development. Over the last several decades, the biodiversity and environmental quality of the northern provinces have seen significant transformations as a result of population growth, urban development, climate change, and the rise in tourist activities. In this research, the LULC maps of Amol City were created for the years 2000 and 2020 using remote sensing data. Additionally, using the CA-Markov model, a simulation was conducted for the year 2035, considering two scenarios: Business-As-Usual (BAU) and Ecological Protection (EP). To assess the spatiotemporal changes occurring at HQ, we integrated the InVEST-HQ model with the CA-Markov model. The findings indicate a significant decline in overall HQ in the city of Amol between 2000 and 2020, mostly due to urbanization and agricultural expansion. Between 2020 and 2035, according to the BAU scenario, the landscape pattern and HQ will continue to deteriorate, following the previous trend of decline. The EP scenario, on the other hand, will be critical in stabilizing and supporting the area's HQ. This emphasizes the significance of preserving ecological spaces like forests and grasslands. The study's maps and findings may assist local managers and related organizations in implementing more efficient plans and solutions for the preservation of these ecosystems.

Objective: Iraq is one of the countries that has seen population growth and rapid urbanization. This growth may lead to increased energy needs in various sectors such as transportation, construction, industry and services. Investigating the effect of population growth on energy efficiency can improve energy consumption in the country. Because energy efficiency reduces energy waste, reduces costs and increases economic competitiveness. Considering the importance of this issue, the main goal of this study is to investigate the impact of urbanization on energy efficiency during the period from 1990 to 2022.
Methods: In this study, energy efficiency is estimated by data envelopment analysis (DEA) method, and then by ARDL method, the effect of urbanization rate on it is investigated.
Results: The results showed that urbanization had a positive and significant effect on energy efficiency in Iraq. Also, based on other results of this study, the impact of the variables of GDP growth, human capital index, gross fixed capital formation, foreign direct investment and industrial added value on energy efficiency is also positive and significant, and the trend of energy efficiency in Iraq, despite its fluctuation, It is somewhat bullish.
Conclusion: Urbanization can affect energy efficiency through various channels, so as to strengthen energy consumption patterns and the effectiveness of energy policies in order to improve efficiency.

From urbanization, the phenomenon of the urban temperature island follows which the city rises and increases from energy to cool. In this research, the role of local factors in the creation and development of heat islands in the city of Ahvaz during the hot period from 2000 to 2015 was investigated using Landsat 7 and 8 satellite data. In order to evaluate the biophysical changes of the land surface in Ahvaz city, the changes of vegetation difference indices were taken by Tokanga-Tag threshold method. By using the kriging method and the low speed zones of Ahvaz, the thresholds of the closest and maximum temperature of Ahvaz city, it appears that this change can cause a change in the local climate. The results of Moran's spatial autocorrelation are a confirmation of the lack of spatial correlation of ground surface temperature in Ahvaz. The evaluation of the northern maps showed that as we move from the southern regions to the northern regions, the temperature increases due to the increase of green space and the increase of barren lands. There is a sharp temperature difference between the central and suburban areas of the city, because of the establishment of industrial companies, District 8 has formed the most stable islands in this area of the city. Residential areas have had less impact on the creation and expansion of thermal islands than industrial and barren areas.
