- The article tried to study the public transport role as one of the means that contribute to sustainable urban development by investigating the effect of the coverage rate for public transport on the number of those who use public transport in the neighbourhoods of Kut city. This article investigates the link between public transportation and supportive urban design trends. The research spatial and temporal limits are represented by the municipal boundaries Al-Kut city, which are shown in the master plan of the city for the period 2008–2012. The results showed a positive but weak relationship between public transport (variable factor) and the proportion of public transport coverage and population density (independent factors). These factors do not explain the apparent, which is confirmed by the high Bo value and its great reliability, and this result is inconsistent with the hypothesis that states a positive effect between public transport and the coverage rate. However, this relationship is abnormal and indicates an imbalance in the distribution of land uses and the provision of services in the structure of Kut city. Furthermore, it is a negative indicator of the city’s structure, where a good and efficient structure requires a strong relationship. As for public transport passengers, they seem to be restricted by this for poor services.

- Solid waste is one of the leading environmental problems affecting human lives. Selecting a landfill where waste is disposed of is a complicated issue that related to many factors and regulations. In this study, the optimal sanitary landfill site for An-Najaf city was assessed using the GIS and weight criteria method. Eight appropriate criteria were selected, which are: urban area, rivers, roads, soil types, elevation, wind, slope, and archaeological, historical and religious sites. Moreover, the weighting of the criteria by using experts’ opinion and previous similar literature. The “weighted overlay tool” is then applied to get a map of the significance index for selected landfill sites. Seven suitable sites with an area of 177,762,986 m2 and form 0.62% from the total city area can accommodate the solid waste generated for a period, not less than ten years10 years.

- Most rivers in developing countries are facing water contamination problem. Therefore, saving water quality by complying with the industrial, drinking, and agricultural allowable standard limits has been difficult. This study aims to assess Shatt Al-Kufa water quality as one branch of the Euphrates River by calculating three types of water quality indices in two cases, excluding and including the phosphate (PO4) consentration, as it was the parameter that most met the standard. The used water quality indices are the Weight Arithmetic Water Quality Index (WAWQI), the Canadian Council of Ministers of the Environment Water Quality Index (CCMEWQI) and the Oregon Water Quality Index (OWQI). Fifteen parameters were analyzed, including pH value, Biological Oxygen Demand, Turbidity, Total Hardness, Orthophosphate, Sulphate, Nitrate, Alkalinity, Potassium, Sodium, Magnesium, Chloride, Dissolved Oxygen, Calcium and Total Dissolved Solids. The results show that the average WAWQI for three stations, including PO4, were 33.79, 43.75 and 37.62, which is good water. However, in excluding PO4, the water quality was characterized as very poor depending on the resulting values (86.62, 88.86 and 91.91, respectively). The CCMEWQI values for three stations were 63.83, 60.40 and 55.69, including PO4, so the water quality was fair and marginal. According to OWQI, the water quality for three stations was very poor in two cases since the OWQI value less than 59. Pearson correlation shows a good link, especially total hardness and total dissolved solids with salt.

- The lack of analys is tools that respond to spatial heterogeneity and the failure to adopt them as tools to assess problems, and the low life quality of Iraqi c ities represent this study's problem. Hence, this study aims to analyze the relationship b etween public transportation and urban form patterns using spatial analys is and shed light on the contribution of spatial analysis as practical planning tools to increase the public transport contribution. The importance of the study can be summarised in the following two reasons; the first is the adoption of a new model for spatial analyzes, which is weighted geographical regression. The second reason is the attempt to activate public transport. Therefore, it should be known that makes public transportation more attractive to the user, both for new areas and future development. The study hypothesis includes that spatial analyzes are more appropriate tools for studying spatial phenomena and are compatible with postmodernity. Finally, the current study introduced a demographic and good urban design that fac ilitates the residents' access to public transport services.

Konferensbidrag (refereegranskat)abstract
- Maintaining natural processes and supporting social and economic growth depend heavily on water supplies. However, Future climate is predicted to bring higher temperatures, which will increase evapotranspiration; lower precipitation totals; and changes in the seasonal pattern of precipitation. Iraq is more vulnerable to climate change than other nations due to the underdeveloped and fragile water management systems there, as well as the country's desert and warmer environment and increasing sensitivity to extreme weather events. The present work aims to analyse the literature dealing with climate change's effects on water resources in Iraq. The Scopus database was searched using the keywords (Iraq, models of climate change, and water resources). Most models study the effect of high temperatures and evaporation on water resources using different tools, the most important of which are SWAT, LARS-WG, and HEC-HM. The analysis of previous studies shows that the results of all the literature concordant that Iraq is on the verge of severe water scarcity due to high temperatures and the resulting decrease in rainfall, increase in evaporation, decrease in vegetation cover and increase in desertification.

- Developing countries suffer from the effects of climate change on water resources more than other countries. This paper aims to specify the undergraduates’ knowledge about climate change effects on water resources. This study was conducted through a questionnaire distributed using Google form in May 2021. Descriptive analysis was used to display the level of awareness, and then the correlation between the respondents’ gender, stage, and scientific specialization were analyzed. The results showed that the general knowledge for all questionaries ranged between 40 and 50 %. Moreover, a weak positive correlation with the highest Spearman’s rho of 0.15 was shown for the students’ gender with their understanding of climate change main cause by 0.06 for the academic stage versus knowledge of climate change causes. Moreover, the results indicated a weak role for university education in exchange for a prominent role for television and social media in raising awareness. The research recommends integrating the Environmental Education (EE) programs into the Iraqi educational systems as it proposes a systematic educational method through which climate change and other environmental problems may be addressed holistically at all educational levels.

Tidskriftsartikel (refereegranskat)abstract
- This study intends to evaluate university students’ awareness regarding water pollution in Iraq to show the environmental education contribution in reducing water pollution. The study was conducted in Wasit university, Wasit province, Iraq by field questionnaire survey with 388 students from the civil engineering department and engineering college. The questionnaires were divided according to the pollution causes into industrial, agricultural and sewage water pollutants. The data were analyzed utilizing the thematic analysis to assess environmental knowledge and awareness of water pollution risks. The results show that most students have high interest in environmental conservation, yet, a lack of education in general environmental education, as the educational curriculum focuses on theoretical aspects more than the practical ones. The results also show that the media role is inactive concerning environmental awareness of water pollution. This study provides a scientific view of policymakers for potential future conditions to find solutions that achieve sustainability goals.

- This study aims to analyze the spatial distribution of the epidemic spread and the role of the physical, social, and economic characteristics in this spreading. A geographically weighted regression (GWR) model was built within a GIS environment using infection data monitored by the Iraqi Ministry of Health records for 10 months from March to December 2020. The factors adopted in this model are the size of urban interaction areas and human gatherings, movement level and accessibil-ity, and the volume of public services and facilities that attract people. The results show that it would be possible to deal with each administrative unit in proportion to its circumstances in light of the factors that appear in it. So, there will not be a single treatment for all areas with different urban characteristics, which sometimes helps not to stop social and economic life due to the imposition of a comprehensive ban on movement and activities. Therefore, there will be other supportive policies other than the ban, depending on the urban indicators for each region, such as reducing external movement from it or relying on preventing public activities only.
