Cagar Biosfer Bromo Tengger Semeru Arjuno (CB-BTSA) dan Cagar Biosfer Blambangan (CB- B) di Jawa Timur diharapkan dapat menjadi model pengelolaan kawasan secara berkelanjutan. Kendala dan tantangan dalam pengelolaan cagar biosfer tersebut adalah permasalahan tenurial yang dapat mengannggu kegiatan konservasi di kawasan inti dari cagar biosfer. Tujuan penelitian ini adalah mendeskripsikan cagar biofer di Jawa Timur dan mengetahui permasalahan tenurial yang terjadi di kawasan CB-BTSA dan CB-B yang menjadi kunci dalam keberhasilan pengelolaan cagar biofer. Penelitian ini menunjukkn bahwa CB- BTSA dan CB-B adalah kawasan strategis dalam program konservasi dan pembangunan berkelanjutan di JAwa Timur. Konfik tenurial masih terjadi, dan beberapa aspek yang melatar belakangi terjadinya konfik. Beberapa aspek tersebut antara lain adalah tuntutan ekonomi, tumpang tindih kebijakan, pemahaman yang salah akan status tanah, mis-informasi dan komunikasi, disharmonisasi hubungan komponen masyarakat,
