Özet:

 Erosion is the process of soil degradation caused by water, wind, and human activities, leading to reduced agricultural productivity and significant environmental and economic challenges. In this study, the ICONA method was employed to assess erosion risk in the province of Malatya. ICONA is an effective approach for creating risk maps, taking into account parameters such as slope, lithology, land use, and vegetation density. Using Geographic Information Systems GIS and Remote Sensing RS techniques, it was determined that 20.17 of Malatya is at low erosion risk, 64.99 at moderate risk, and 14.19 at very high risk. Areas with steep slopes were found to exhibit very high erosion risks. The regions with the highest erosion risk are predominantly located in the northern and southern parts of Malatya on sloped terrains. Conversely, areas with no slope but high erodibility due to lithological properties were identified as having moderate erosion risk. The findings indicate that erosion risk reaches critical levels in the northern regions, characterized by steep slopes and insufficient vegetation cover. These results provide guidance for soil conservation and sustainable land management. This study contributes to understanding regional erosion risks and offers a replicable method for similar regions. Measures to preserve natural resources should be based on scientific evidence.

 Erozyon, toprağın su, rüzgâr ve insan faaliyetleriyle aşınması sürecidir ve tarım arazilerinin verimliliğini azaltarak çevresel ve ekonomik sorunlara yol açmaktadır. Bu çalışmada, Malatya ilinin erozyon riskini belirlemek için ICONA yöntemi kullanılmıştır. ICONA, arazinin eğimi, litolojisi, arazi kullanımı ve vejetasyon yoğunluğu gibi parametreleri dikkate alarak risk haritaları oluşturmada etkin bir yöntemdir. Çalışma kapsamında Coğrafi Bilgi Sistemleri CBS ve Uzaktan Algılama UA teknikleri kullanılarak, Malatyanın 20.17sinin düşük, 64.99unun orta ve 14.19unun çok yüksek erozyon riski taşıdığı belirlenmiştir. Malatyanın erozyon riski genellikle eğimin fazla olduğu alanlarda çok yüksek olarak çıkmıştır. Erozyon riskinin çok yüksek olduğu yerler ise Malatya ilinin kuzeyi ve güneyinde eğimli alanlarda yayılış göstermiştir. Ayrıca, eğimin olmadığı ancak litolojik özelliklere bağlı olarak aşınabilirliğin yüksek alanlar ise orta derecede erozyon riskinin olduğu alanlar olarak yayılış göstermiştir. Elde edilen bulgulara göre, erozyon riski, dik eğimler ve yetersiz bitki örtüsü ile karakterize edilen kuzey bölgelerinde yüksek seviyelere ulaşmaktadır. Bulgular, toprak koruma ve sürdürülebilir arazi yönetimi için rehber niteliğindedir. Bu çalışma, bölgesel erozyon riskinin anlaşılmasına katkı sağlamakta ve benzer bölgelerde uygulanabilir bir yöntem sunmaktadır. Doğal kaynakların korunması için alınacak önlemler bilimsel temellere dayandırılmalıdır.
