As consequences of diseases and environmental degradations linked to this development, there are currently 250,000 ha 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. specialized Aquaculture Abandoned ponds VHSR images Indicator Supervised classification Spatial and temporal survey INDONESIE BALI 040 038 036 126 131 Part B No spécial 49-60 2018 0025-326X https://www.documentation.ird.fr/hor/fdi:010073617 10.1016/j.marpolbul.2017.03.059 0025-326X [F B010073617] https://www.documentation.ird.fr/hor/fdi:010073617 https://www.documentation.ird.fr/intranet/publi/2018/07/010073617.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2018-09-03 2023-07-11 fdi:010073617 fre
