“…As a consequence, ponds were highly connected to each other. They could be considered as nodes in a connected network of water, wildlife, pathogenic agents and other processes such as nutrients exchanges (Amundrud et al, 2009, Frazer, 2009Allen et al, 2016). In an epidemiological study, Tendencia et al (2011a) showed that sharing of water source with other farms, use of the same receiving water source, and water change dependent on the tide, as in the Perancak estuary, increased the risk of disease development.…”

From the 1980's, Indonesian shrimp production has continuously increased through a large expansion of cultured areas and an intensification of the production. As consequences of diseases and environmental degradations linked to this development, there are currently 250,000ha of abandoned ponds in Indonesia. To implement effective procedure to undertake appropriate aquaculture ecosystem assessment and monitoring, an integrated indicator based on four criteria using very high spatial optical satellite images, has been developed to discriminate active from abandoned ponds. These criteria were: presence of water, aerator, feeding bridge and vegetation. This indicator has then been applied to the Perancak estuary, a production area in decline, to highlight the abandonment dynamic between 2001 and 2015. Two risk factors that could contribute to explain dynamics of abandonment were identified: climate conditions and pond locations within the estuary, suggesting that a spatial approach should be integrated in planning processes to operationalize pond rehabilitation.
