The purpose of this study was to identify the potential site for sustainable aquaculture development in Mymensingh district using GIS as a tool.
In this paper we describe the construction of an online GIS database system, hosted by WorldFish, which stores bio-physical, ecological and socio-economic data for the ‘Coral Triangle Area’ in South-east Asia and the Pacific. The database has been built in partnership with all six (Timor-Leste, Malaysia, Indonesia, The Philippines, Solomon Islands and Papua New Guinea) of the Coral Triangle countries, and represents a valuable source of information for natural resource managers at the regional scale.
Kolleru lake, India’s largest fresh water lake, and lone Ramsar site in Andhra Pradesh state have undergone tremendous changes due to development of aquaculture. Large-scale aquaculture practices, increased industrial activity, increased number of human settlements, etc. have exploited the lake’s resources which created an extensive ecological imbalance, hence instabilising the sustainability process. The present study highlights the assessment of aquaculture in Kolleru lake using multi-temporal satellite datasets.
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 is based on a first phase of a study in the Muthurajawela-Negombo wetland complex and aims to assess the overall spatial linkages between ecological and socioeonomic aspects of the wetland system using a geospatial model; incorporating biophysical and socioeconomic parameters for analysing and modelling the changes in the coastal wetland-agriculture-aquaculture complex.
A multiple purpose wetland inventory is being developed and promoted through partnerships and specific analyses at different scales in response to past uncertainties and gaps in inventory coverage. A partnership approach is being promoted through the Ramsar Convention on Wetlands to enable a global inventory database to be compiled from individual projects and analyses using remote sensing and GIS. Individual projects that are currently part of this global effort are described.
The Hindu Kush-Himalayan (HKH) region, home to the largest concentration of glaciers outside of the polar region, is the ‘water-tower’ of Asia. The HKH mountain ecosystem provides life support services to almost a third of humanity. Many mountain issues such as management of water resources, climate change, biodiversity conservation and hazard mitigation are interconnected in nature and, therefore, need to be considered holistically.
Fish museums across the world are a repository of historical data on fish abundance and occurrence. These occurrence points when mapped provide a picture of present-day and earlier fish distribution. The accuracy of the map will depend on how exhaustive the museum collection is for the area, and also on the museums’ collection practices (comprehensiveness and survey design).
The project 'Community-based Fish Culture in Seasonal Floodplains' (henceforward the community-based fish culture project), CGIAR Challenge Program on Water and Food, aims to enhance fish production in seasonal floodplains to improve and sustain rural livelihoods in Bangladesh, Cambodia, China, Mali and Vietnam.
Andaman and Nicobar Islands houses vivid ecological habitats with diverse set of ecosystems varying from low altitude sandy beach forest to high altitude dense humid evergreen forests. The islands on account of their isolation, harbors a phenomenal degree of endemic plants and animals species along with rich marine life. The present study, using the application of earth observation system and geospatial tools aims to compare and explore the intra variability of landscape structure as well as the diverse vegetation pattern in North Andaman and Baratang Islands of the Andaman group.
