Tesis ini berupaya mendalami pola-pola adaptasi yang dikembangkan penduduk Pesisir Krui menanggapi tantangan/dilema dalam mempertahankan keserasian dengan lingkungan hidupnya dari perspektif ketahanan nasional. Penelitian ini adalah penelitian kualitatif dengan metode deskriptif. Hasil penelitian menunjukkan bahwa pola-pola adaptasi yang dikembangkan masyarakat dalam merespon keterbatasan lahan dan sumberdaya alam, intervensi ekonomi pasar, dan intervensi politik telah melemahkan kohesi sosial dan memicu munculnya gejala-gejala sosial yang mengarah pada konflik dan tindak kekerasan yang membahayakan stabilitas keamanan sehingga mengganggu ketahanan nasional. Penelitian menyarankan agar kebijakan-kebijakan pemerintah terkait kehutanan harus memperhatikan aspek ekologi, ekonomi, sosial, dan budaya masyarakat setempat serta tidak bersifat represif dan diskriminatif. Selain itu, perlu upaya penguatan kelembagaan adat dan penciptaan diversifikasi lapangan pekerjaan untuk mengurangi ketergantungan masyarakat terhadap sumberdaya hutan.
