Abstract :

The goal of this work was to determine the optimal locations for urban growth in Kabul city using an integrated GIS-AHP model and Land Suitability Analysis (LSA). The study’s findings demonstrated that GIS-AHP is a useful approach for urban planning and ecological management. Maps were normalized using the pairwise comparison matrix technique using the generated criteria. Each model’s weights were created by comparing them according to their relative importance. Weight Age Average (OWA) and Weighted Linear Combination (WLC) were used to combine criteria weights and maps. To assess if a piece of land is suitable for urban development to determine which area was suitable for urban development, six thematic layers—slope, road, land use, river, settlement, and elevation—were used. AHP calculated their weighted scores based on the pairwise comparison.

The linear combination approach was used to multiply each factor’s weight and score, and the outcome was then multiplied to make the urban development appropriate. 45.3 square kilometers of land were deemed highly suitable, 191.77 square kilometers were deemed fairly acceptable, 72.14 square kilometers were deemed marginally suitable, and 0.79 square kilometers were deemed unsuitable.
