Lahan merupakan sumber daya yang sangat penting untuk memenuhi segala kebutuhan hidup sehingga dalam pengelolahannya harus sesuai dengan kemampuannya agar tidak menurunkan produktivitas lahan. Lahan kritis merupakan lahan atau tanah yang saat ini tidak produktif karena pengelolaan dan penggunaan tanah yang tidak atau kurang memperhatikan syarat-syarat konservasi tanah dan air, sehingga lahan mengalami kerusakan, kehilangan atau berkurang fungsinya sampai pada batas yang telah ditentukan. Tujuan dari penelitian ini (1) untuk mengetahui bobot masing-masing kriteria (2) sebaran lahan kritis di Sub DAS Amohalo dengan mengunakan metode Multi Criteria Evaluation (MCE) dengan teknik analisis Analisis Hirarky Proses (AHP) untuk menentukan bobot kriteria dari masing-masing parameter penentu lahan kritis. Pemetaan lahan kritis menghasilkan bobot masing-masing kriteria penentu lahan kritis dimana penutupan lahan bobot 45%, kemiringan lereng bobot 19%, tingkat bahaya erosi bobot 14%, produktivitas bobot 12%, dan manajemen lahan bobot 10% dengan total bobot 100%. Sebaran lahan kritis di Sub DAS Amohalo menghasilkan lima kelas kriteria yang didominasi kelas potensial kritis mencapai luas Wilayah 5656,96 ha dari hasil analisis tersebar di Wilayah Kota Kendari dan Wilayah Konawe Selatan, luasan terendahnya terdapat pada kelas sangat kritis dengan luasan 11,65 ha yang tersebar di Kecamatan Moramo Utara, Baruga dan Kambu.
