Today, the absence of legitimate comprehension of the peculiarity of climate change and its ramifications on different areas in Iran, has caused different difficulties for residents, administrators and organizers; These challenges include agricultural decline, drought and floods, poverty, and increasing migration. Along these lines, this study means to explore the impacts of climate change on spatial-locational population changes in Iran, and furthermore, for the subsequent advance, a more itemized investigation of the examination region, i.e., climate migrants living in the city of Karaj. The method of this research is descriptive-analytical and its nature is causal (post-event). This research is cross-sectional in terms of time and covers the period of 1996-2016. The findings of the study, which is the product of data analysis and mapping, as well as 400 questionnaires filled out in 8 districts of Karaj, show that the cause of more than 10% of migration to Karaj is due to the climate change. The city of Karaj had climatic migrants from 9 territories of the country, a large portion of which were from Khuzestan territory. Additionally, the biggest number of climatic migrants live in two zones: Zone 2 and zone 5 of Karaj city. The greater part of the climate migrants has chosen Karaj as their home city because of open positions, the vicinity of Karaj to Tehran city and the low residing costs in this city contrasted with Tehran.

High temperature during seed set and seed filling can reduce yield and seed quality. In order to evaluate the effect of high temperature during planting date and also plant density on soybean seed quality, an experiment was conducted at two locations, namely, Seed and Plant Certification and Registration Institute in Karaj and Agricultural and Natural Resource Center of Moghan, in 2013. The studied factors were included planting date (5th of May, 5th of June and 5th of July), plant density (300, 400 and 500 thousand plant/ha) and soybean varieties (Williams and L17) were sown in the rate of 40 plants per m-2 at 5th May, 5th June and 5th July. The experiment was conducted as a factorial based on a randomized complete block design (RCBD) with three replications. The results of standard germination test showed that in Moghan area, the highest normal seedling percentage (92.1%) was obtained at fifth of June and in Karaj area, it (96.2%) was gained at fifth of July. In addition, it was noticed that cv. L17 in Moghan and cv. Williams in Karaj had the highest normal seedling percentage. The results of accelerated aging test was cleared that the normal seedling percentage in karaj was more than Moghan area and it showed that the quality of seed that were produced in Karaj was better than Moghan area. There was no significant difference between areas in 300 and 400 thousand of plant/ha and in these both density, the result of Karaj was better than Moghan area, but there was significant difference between normal seedling percentage after accelerated aging test in Karaj (77.6%) and Moghan (58%) in 500 thousand plant/ha. The highest seedling vigor index (11.75) was obtained in 400 thousand plants/ha at fifth of July in Karaj area and the lowest rate of it (5.41) was observed in 300 thousand plants/ha at fifth of June in Karaj area.

 This article studies and analyzes the role of Karaj prisons in political, social and cultural changes of this metropolis between 2006 and 2019. accordingly, the main question of the present research is: What is the role of Karaj metropolis prisons on the political, social and cultural changes of this metropolis between the years from 2006 to 2019?The temporary response to the main question is: Karaj city has slowed the political development process, also caused social challenges such as increasing crime and informal settlements and cultural challenges between 2006 and 2019 in Karaj metropolis.Alborz province is one of the most important and populated regions of the country. There are significant development differences between different regions of Alborz province. The most important development planning steps are setting development goals and reducing imbalance. To identify regional disparities and provide regional development indicators, we need to review the current situation and indicators of development in different economic, social and cultural sectors in Karaj. The present study, is an applied research which is conducted through survey and descriptive – analytical from the perspective of purpose.

 Informal housing and squatting is a problem that is not unique to Iran, but to many countriesThe countries of the world are facing it. Also, Iran is one of the developing countriesIt is considered that it suffers from the phenomenon of informal settlement like these countries. Unfortunately, this phenomenon quicklyIt is growing and expanding and there are many social, economic, cultural, security and environmental problemsIt has been created in most cities, especially the big cities of Iran, including the city of Karaj. So according toThe importance of the subject, this research is a case study on the pattern of spatial-spatial organization of informal settlementsMurad hill gives Karaj water.The formation of the informal settlement and biological center of Murad Ab Karaj Hill, which started in the late 50s, withMarginal location in Karaj city has special features. Moradab hill in the eastern part of Karaj cityIt is located in the lands of Islamabad and under the supervision of the 1st district of the 12 districts of Karaj municipalityIs. The disturbances and poverty prevailing in the area have caused the social and cultural relations to be appropriateIt should not be formed in this place in accordance with other parts of the city, which hinders the communication and connection of this space withOther urban complexes have been in the process of forming their historical period, hence this space (Tepe Murad(water) continued to live in a fragmented, isolated and introverted relationship with others, and this problem causedIt was decided that the said center does not have the necessary legitimacy as an urban biological space and the plansThere was no effective action taken in the area to solve the main problem and the problem is still in the arearemains Therefore, according to the importance of the subject, spatial-spatial organization of this space and planning for improvementThe current situation has been of great importance. Because the intensity of the development of the study area and speedIncreasing migrations and informal settlements on the one hand and the lack of ability of the municipality and related institutionsImproving informal contexts and organizing them, on the other hand, the necessity of research regarding pattern determinationSpatial-place organization in Moradab Hill has made Karaj inevitable. Based on this researchIt explains the pattern of spatial-spatial organization of informal settlements in Murad Ab Karaj.The current research was carried out with the aim of developing spatial-spatial organizing strategies of informal settlements. In this regard, data was analyzed using the descriptive-analytical method as a combination of quantitative and qualitative methods. The research sample includes 50 urban experts and specialists who were purposefully sampled. In order to achieve the objectives of the research, SWAT analysis was used first and then QSPM matrix was used. In the following, the T-test was used to evaluate the current situation of the informal settlement of Moradab Hill in Karaj. The results of the SWAT analysis led to the formation of 14 strengths, 26 weaknesses, 17 opportunities and 17 threats. Next, using quantitative strategic planning (QSPM), the spatial-spatial organization strategy of this settlement was developed. The results of the SWAT analysis led to the formation of 14 strengths, 26 weaknesses, 17 opportunities and 17 threats. Also, based on the results of quantitative strategic planning, 5 strategies were identified for the organization of informal settlements in Murad Ab Karaj hill, which include: preparation of a comprehensive study plan for organization related to sustainable urban regeneration in the form of a comprehensive joint action plan with regard to short-term time levels , mid-term, long-term and defining the role of each of the public, private and public participation organizations and institutions; facilitating the entry of the private sector into urban regeneration projects; organizing informal settlements; Using the capacities of the residents of informal settlements to recreate the target neighborhoods and create employment; Increasing security and preventing the occurrence of social harms through making available urban spaces in neighborhoods. In addition, the results of the t-test showed that none of the indicators mentioned in this settlement were in a favorable condition and the average scores obtained from the respondents were lower than the theoretical average at a significance level of 0.01.

Increase in urban population has led to the uncontrolled and unplanned expansion of cities, which has led to an increase in energy consumption, including electricity. The aim of this study is to analyze the impacts of Karaj’s form on electricity consumption and the length of power network lines as carriers. The required data of this applied and descriptive-analytical study was collected through the library resources and going to organizations. The statistical population is 173 neighborhoods of Karaj city. The geographic weight regression (GWR) tool was used to determine the spatial variation between the independent and dependent variables. The results showed that the form of Karaj city highly compacts the neighborhoods of Regions 5, 1, 7, and 2, but the neighborhoods of Regions 3 and 4 have a spiral state due to the villas and the high infrastructure of the villa gardens in part of the city. Based on the results obtained from local weight regression, the population density index as one of the important indicators of city form has the highest impact on electricity consumption in Karaj (R2 equals 78). That is, the city form index, according to this index at the 95% confidence level, justifies 78% of electricity consumption. Moreover, the entropy index as one of the indicators of the independent variable (city form) with (R2=0.66) has the highest impact on the length of Karaj electricity network lines. Therefore, the results showed that the form of the city of Karaj has a spatial relationship of more than 0.50% on the electricity consumption and the length of the lines of the power grid of the city.
