Analisis Daya Dukung Gizi Hutan Kemasyarakatan di Kabupaten Lampung Barat

Abstract

Kelangsungan ketersediaan pangan dihadapkan pada tantangan dan masalah terutama produksi pangan yang semakin terbatas akibat adanya konversi lahan pertanian menjadi lahan non pertanian yang diakibatkan oleh semakin meningkatnya jumlah penduduk yang membutuhkan lahan untuk pemukiman dan untuk melakukan aktivitas perekonomian. Sebagian besar petani di pedesaan adalah petani berlahan sempit dan penggarap yang tidak memiliki lahan sendiri. Kendala yang sering dihadapi oleh para petani untuk melakukan proses usaha tani adalah karena keterbatasan modal yang dimiliki dan terbatasnya kemampuan berproduksi sehingga menyebabkan produktivitas usaha tani relatif stag nan.
