Prediction Model of Air Temperature in Relation to Field and Remotely Sensed Data in Baghdad Greater Area

Remote Sensing and GIS Techniques offer significant potential as a quantitative approach for monitoring urban growth and environmental changes on landscape. This study assesses urban growth and drought monitoring in University of Baghdad campus from 1988 to 2022 by using Land Use/Land Cover (LU/LC) and spectral indices: Normalized Difference built up Index (NDBI) to detect and map built-up areas or urban developments and Normalized Difference Moisture Index (NDBI) used to detect areas experiencing water stress. The (LU/LC) and NDMI values were classified into five categories: High Vegetation, Built -up Area, Low Vegetation, Moist Soil and Barren Soil. Built -up Area of (LU/LC) recorded 6.578 km2 (19%) in 1988 which increased to 9.009 km2 (26%) in 2022 representing a 36% increase in the percentage, whereas Built -up Area of (NDBI) recorded 7.617 Km2 (22 %) in 1988 and decreased to 5.887 Km2 (17 %) in 2022 representing a 22% reduces in the percentage of built-up area relative to the total area. NDBI estimated values were (- 0.14 -0.58) and (- 0.4 - 0.01) for 1988, 2022 respectively. The estimated NDMI values were classified into five categories: Very low Moisture, low Moisture, Medium Moisture, High Moisture and Very High Moisture. NDMI values recorded (- 0.29 -0.29) and (- 0.06 - 0.25) for 1988, 2022 respectively. The study emphasized the importance of using remote sensing and geographic information systems (GIS) techniques in landscape design and management towards implementation of effective strategies for enhancing environmental sustainability.

This study aims to investigate changes in vegetation cover of the University of Baghdad campus by Normalized Difference Vegetation Index (NDVI) and Soil-Adjusted Vegetation Index (SAVI) as a tool to determine the changes in vegetation cover on the University landscape were used for the period 1988 and 2022 for two seasons (Winter and Summer). Land cover was divided into four categories: Barren & buildings, Low, Medium, and Dense vegetation. The results showed an increase in NDVI values in winter (-0.2-0.5), and (-0.1-0.9) in 1988, and 2022 respectively, and recorded in summer (-0.3-0.5) and (-0.04-0.4) in 1988, and 2022 respectively. The highest value was recorded in winter of 2022. Barren & buildings recorded the highest value 1470630 Km2 with 43% in summer of 1988 while in 2022 recorded 1411156 Km2 with 40%, for both seasons. The Low vegetation recorded the highest value 130031 Km2 with 377% in winter 1988 and the lowest was recorded at 941671 Km2 with 28% in summer 2022. Medium vegetation was recorded the highest 787580 Km2 with 22% in winter 2022 and lowest 667730 Km2 with 19 %. Dense vegetation was the highest 413614 Km2 with 12 % in summer 2022 while the lowest was recorded 211763 Km2 with 6 % in winter 1988. SAVI values were recorded in winter (-0.3-0.7), (-0.1-0.4) in 1988 and 2022 respectively and in summer (-0.4 - 0.7)(-0.06 - 0.6) in 1988 and 2022 respectively. The results showed slight differences from NDVI values of vegetation cover (Dense). The integration of remote sensing and geographic information systems is an effective and sustainable tool for studying land cover changes in order to obtain reliable and accurate rapid and economical results.

Riverbanks are one of the most effective places in connecting residents with the river, and neglecting their, especially from the vegetation aspect, leads to the natural and functional underutilization of the riverbank. Due to the lack of attention to urban green design in Baghdad and the scarcity of studies related to this aspect, the research problem of knowledge deficiency in the fundamentals of plant design for riverbank edges has emerged. Therefore, the research adopting the descriptive analysis method of the vocabulary discussed in previous studies related to the development of riverbanks to formulate a theoretical framework applicable to evaluate the local environment of the riverbank at the Al-Athamiyah site and study the impact of the location from both natural and cultural perspectives on the nature of plant design for the riverbank. The study included some indicators to develop a theoretical framework that can be applied to the current situation. The most important findings of the research are that use of local plant species contributed to supporting natural and environmental values, reinforcing the cultural aspect and local heritage and plants can be utilized to create activities that enhance the effectiveness and utilization of the riverbank.
