In Bangladesh inland pond aquaculture supplies 45% of freshwater fish, an important protein source for its increasing population. To maintain the desired productivity growth of the aquaculture sector will mean bringing more water bodies into production. With the high potential areas already developed, increasing aquaculture productivity in the more challenging areas needs to be more strategic and well-supported with relevant information about the opportunities and limitations faced in these areas.
Global aquaculture production increased with an average rate of 10% per year since 1990 and 90% of aquaculture production comes from developing countries thus providing livelihood and income especially to marginal groups who have limited access to resources such as agricultural land and financial capital.
This study was an attempt to apply land-based GIS analysis for freshwater aquaculture planning in the Red River Delta of Vietnam. It was based on diverse data sources in order to help decision makers at the site and also to contribute to the modelling of selection processes for aquaculture development planning in the region.
This paper highlights Geographical Information System (GIS) applications in an on-going, three-year project to develop spatial decision-support tools for identifying recommendation domains (places and sets of conditions) that determine the potential and feasibility for adoption of smallholding pond-aquaculture systems to aid strategic aquaculture planning and development. Implemented at sub-national scale, the project is piloted in Bangladesh, Cameroon, China and Malawi.
An attempt was made to conduct spatial assessment of the pattern and extent of damage to coastal aquaculture ponds along the east coast of Aceh province in Sumatra, Indonesia, resulting from the tsunami event of 26 December 2004. High-resolution satellite imagery, i.e., SPOT-5 multispectral scenes covering the 700 km stretch of the coast, acquired before and after the tsunami, were digitally enhanced and visually interpreted to delineate pockets of aquaculture ponds that were discerned to be damaged and relatively intact.
