The Bajau are a seafaring people with an estimated population of 1.1 million who live on the seas and shores of the islands of Southeast Asia, the Suru Islands in the Philippines, the Malaysian state of Sabah, and eastern Indonesia. They are particularly vulnerable to displaced migration even among inhabitants of the maritime community of Southeast Asia. I would like to introduce the survival strategies that the Bajau, who use their high mobility and adaptability to secure marine resources, use to live on the sea.
