Aquaculture contributes substantially to global food and nutrition security and is projected to expand further in response to demand from an increasingly populous, affluent and urbanizing world. Globally, aquaculture has expanded faster than any other major food production system and about 80% of global aquaculture production takes place in Asia. Despite this, Asian aquaculture is generally assumed to be small scale, but the size and tenure of aquaculture farms is poorly documented, and the factors that drive and mediate aquaculture change are understudied; in particular, there are scarce publicly available data on the boundaries of aquaculture “ponds”, which is the fundamental unit of aquaculture practice. Research questions and associated hypotheses that characterize the typology of aquaculture spatio-temporal development in South and Southeast Asia and the drivers and constraints of aquaculture will be addressed. The analysis will be undertaken in four aquaculture hotspot areas in Myanmar, Bangladesh, Thailand and India, which are at different stages of aquaculture development and subject to different drivers and constraints. Aquaculture pond maps extracted for 2015-2024 from Sentinel-1/2 and commercial high-resolution imagery will be generated using refined algorithms based on ones we developed for automatic crop field extraction. Existing (Myanmar, Bangladesh) and new (Thailand, India) aquaculture survey information will complied and collected respectively. A preliminary focusing study to develop a Thailand aquaculture survey was already undertaken April 2023. This poster overviews the research questions and associated hypotheses, and presents prototype results of Sentinel-2 10m aquaculture pond extraction and Sentinel-1 SAR shrimp-farming annual-cycle estimation in central Thailand.
