SHAP-Driven Explainable Artificial Intelligence Framework for Wildfire Susceptibility Mapping Using MODIS Active Fire Pixels: An In-Depth Interpretation of Contributing Factors in Izmir, Türkiye Muzaffer Can Iban, Oktay Aksu Remote Sensing, 2024 Wildfire susceptibility maps play a crucial role in preemptively identifying regions at risk of future fires and informing decisions related to wildfire management, thereby aiding in mitigating the risks and potential damage posed by wildfires. This study employs eXplainable Artificial Intelligence (XAI) techniques, particularly SHapley Additive exPlanations (SHAP), to map wildfire susceptibility in Izmir Province, Türkiye. Incorporating fifteen conditioning factors spanning topography, climate, anthropogenic influences, and vegetation characteristics, machine learning (ML) models (Random Forest, XGBoost, LightGBM) were used to predict wildfire-prone areas using freely available active fire pixel data (MODIS Active Fire Collection 6 MCD14ML product). The evaluation of the trained ML models showed that the Random Forest (RF) model outperformed XGBoost and LightGBM, achieving the highest test accuracy (95.6%). All of the classifiers demonstrated a strong predictive performance, but RF excelled in sensitivity, specificity, precision, and F-1 score, making it the preferred model for generating a wildfire susceptibility map and conducting a SHAP analysis. Unlike prevailing approaches focusing solely on global feature importance, this study fills a critical gap by employing a SHAP summary and dependence plots to comprehensively assess each factor’s contribution, enhancing the explainability and reliability of the results. The analysis reveals clear associations between factors such as wind speed, temperature, NDVI, slope, and distance to villages with increased fire susceptibility, while rainfall and distance to streams exhibit nuanced effects. The spatial distribution of the wildfire susceptibility classes highlights critical areas, particularly in flat and coastal regions near settlements and agricultural lands, emphasizing the need for enhanced awareness and preventive measures. These insights inform targeted fire management strategies, highlighting the importance of tailored interventions like firebreaks and vegetation management. However, challenges remain, including ensuring the selected factors’ adequacy across diverse regions, addressing potential biases from resampling spatially varied data, and refining the model for broader applicability.
Earthquakes in Kahramanmaras; Assessment of Affected Areas and Recommendations for Settlement Regeneration Oktay AKSU, Agne KARLIKANOVAITE-BALIKCI Eurasia Proceedings of Science Technology Engineering and Mathematics, 2023 On February 6, 2023, two catastrophic earthquakes hit Turkey, causing significant damage and casualties. The main causes of these results are improper constructions and settlement placements. Regions where earthquake damage is typical are cities developed on fertile agricultural lands. Site selection for land suitability is one of the main application areas of the Geographical Information System (GIS). The Multi-Criteria Decision Approach (MCDA) has provided consistent and sufficient alternatives to decision-makers for land use planning activities for many years. This study focused on a large area covering five provinces with a total area of 36.409 km2 as the whole region represents 110.000 km2 and is challenging to manage in a single segment. Moreover, the heaviest damages were observed in the study area. Nine criteria were considered while using the weighted overlay function of the GIS via the Analytical Hierarchical Process (AHP). Agricultural and forest regions were excluded from the scope and the entire study area; 84.0% unsuitable, 0.4% low suitable, 1.5% moderately suitable, 11.3% suitable, and 3.2% highly suitable areas were identified for the post-disaster regeneration of settlements.
Considerations on the land management system approach in Turkey by the experiences of a case study Oktay Aksu, Muzaffer Can Iban Survey Review, 2019 In Turkey, applications and activities for the use, acquisition and arrangements of land tenure rights are executed under the authorisation and responsibilities of a variety of public institutions in terms of concerned legislative framework. In this paper, a case study has been implemented for Istanbul not only to evaluate the quality and usability of existing data from different institutions but also to get conclusions and recommendations for future land management works. In the context of this sample work of preparing an inventory for land management and land use in 1:25 000 scale and related synthesis and pre-feasibility analyses; the inventory praxis for urban and rural areas have been undertaken separately. Layer overlay and synthesis of the data in the database are the essential parts of analysing and extracting the outputs supporting land management activities for the purpose of taking correct decisions. In that manner, an overview map of Istanbul's natural and settlement areas has been extracted.
