Application of Earth Observation (EO) Data for Detection, Characterization and Management of Brackish water ponds: Case Studies from Indonesia

  2. 2. "Supporting Blue Growth with innovative applications based on EU e-infrastructures”, 14-15 February 2018, Brussels Background  Shrimp Farming in Indonesia is important for economic growth ( national food security & export), Potential area 2 million hectares.  But it faces many environmental challenges. Since earlier 1990s, there has been continues decrease in production due to disease outbreak.  Other major problems identified in small-scale brackish water aquaculture: • Environmental conditions are not well suited for aquaculture (mainly acid sulfate soils, peat soils and sandy sediments) • Farm management factors (insufficient water supply, ponds dug too deep and cannot be drained out, brackish water supply, algal blooms)
  3. 3. "Supporting Blue Growth with innovative applications based on EU e-infrastructures”, 14-15 February 2018, Brussels  Detail knowledge of environmental and farm management constraints is critical to solve production problems and how limitations can be managed.  FAO Expert Workshop in Rome, Italy 19–21 November 2008 has proposed the use of spatial planning tools including Geographic Information Systems (GIS), remote sensing and mapping as an essential element for data management, analysis, modelling and decision-making in aquaculture.  Practical implementation of the Spatial Planning Tools relating to aquaculture needs can be a big challenge The processes, methods, type of information and visualization?  Case studies : focused only on coastal land based/brackish water aquaculture (BA) Background

  5. 5. "Supporting Blue Growth with innovative applications based on EU e-infrastructures”, 14-15 February 2018, Brussels What is a brackishwater aquaculture system? - None to low agro inputs (fertilizers/pesticides) - Low stocking density (< 3 ind/m2) - Rely on tide for water supply - High agro inputs (artificial feed, fertilizer etc.) - High stocking density (> 15 ind/m2) - Rely on Pump for water supply Extensive IntensiveSemi-intensive

"Supporting Blue Growth with innovative applications based on EU e-infrastructures”, 14-15 February 2018, Brussels Summary • To ensure a maximum adoption of EO products and analysis by spatial environmental planners and aquaculture stakeholders, we must take into account : practicality, accuracy & simplicity • The successful application/adoption of EO data or products will very much depend on the stakeholders or potential beneficiary needs • Poor understanding of the technology (both strength and limitations) could be solved by providing of training to local coastal/marine spatial planners, scientists, NGOs etc. 15/02/2018 15
