| Summary: | The city of Chelghoum El Aïd has experienced rapid urban growth, primarily
driven by a major urbanization event. This expansion has prioritized the
development of natural and undeveloped spaces, rather than investing in
urban infrastructure. As a result, there has been a significant
transformation of open areas, leading to a considerable reduction in green
and natural spaces. In addition to the environmental impact, the urban
expansion of Chelghoum El Aïd has become more pronounced from a
morphological perspective. This is characterized by the densification of
existing urban fabric and the gradual transformation of its original
structure. The city continues to expand beyond its initial boundaries,
gradually integrating previously undeveloped areas. This study analyzes the
urban growth of Chelghoum El Aïd (Wilaya of Mila, Algeria) from a
morphological perspective the city’s growth has predominantly followed a
linear and compact pattern along National Road No. 5 to highlight the role
of urban form in the emergence of urban heat islands. The research employs
across-evaluation of Land Surface Temperature (LST) and the Normalized
Difference Vegetation Index (NDVI), utilizing satellite imagery spanning
the period from 1984 to 2024. The analysis is based on data from Land sat
sensors 5, 8, and 9, processed using ArcGIS 3.2.0 software. The correlation
results indicate an inverse relationship between LST and NDVI indices. The
year 1984 showed the strongest negative correlation (R² = 0.3466) and the
steepest regression slope (-42.33) demonstrating that the decrease in
vegetation cover has significantly contributed to the rise in temperatures
within Chelghoum El Aïd, Since the beginning of the study period,
temperatures have risen by approximately three degrees Celsius. This study
benefits key stakeholders, including ministries (environment, agriculture,
energy), universities and research centers, municipalities, environmental
organizations, and the private sector. These entities use the findings to
enhance urban planning, resource management, and sustainable development. |
