Abstract
Kabupaten Lamongan menyandang gelar “Lumbung Pangan Nasional” karena kekayaan akan hasil pertanian, perikanan, peternakan, dan kehutanan yang melimpah. Namun, pada tahun 2020 konversi lahan produktif yang terjadi sangat pesat dan merupakan yang tertinggi di Provinsi Jawa Timur. Seiring dengan meningkatnya jumlah penduduk dan kebutuhan konsumsi membuat Kabupaten Lamongan memerlukan arahan pemanfaaan lahan melalui pendekatan telapak ekologis. Analisis dilakukan melalui perhitungan biokapasitas, telapak ekologis, keseimbangan daya dukung lingkungan, dan arahan pemanfaatan lahan. Arahan pemanfaatan lahan membandingkan kondisi biokapasitas eksisting 2020, rencana pola ruang 2040, telapak ekologis eksisting 2020 dan 2040. Hasil arahan pemanfaatan lahan diolah menggunakan analisis delphi untuk mendapatkan konsensus dari expert judgment. Hasil penelitian menunjukkan bahwa Kabupaten Lamongan secara agregat mengalami surplus pada level 1 dengan nilai defisit ekologis sebesar 12133297,4`1 Gha atau sebesar 9,0186 Gha/kapita. Biokapasitas lahan lebih besar 1359 % dari 150% dari telapak ekologisnya (BK>150% TE). Kondisi biokapasitas wilayah masih bisa memenuhi kebutuhan penduduk dan lahan surplus dapat mensuplai kebutuhan wilayah lain yang mengalami defisit. Penelitian ini menghasilkan arahan pemanfaatan lahan berupa integrasi, konservasi, normalisasi, rehabilitasi, intensifikasi, dan ekstensifikasi lahan.
