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.
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.
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.
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.
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.
The present study investigates the potential of readily available and easily accessible global data sets to understand regional/local level interactions in wetland systems. The biogeographical zones of India were used a base-frame to select three sites. The study well fits the interests of National Wetland Committee of India to investigate and document fundamental information on wetland extent/distribution. The national partnership with SACON represents this interest.
The present study was carried out in the context of conservation biology research, focusing on the species diversity in the fragmented landscapes of island ecosystem. The study analyzed the levels of forest fragmentation and its effect on species diversity in the North Andaman Islands using satellite remote sensing data and a GIS-based fragmentation model in conjunction with phyto-sociological analysis. Results depict that the model performed well when the forest is considered as a single unit, compared to the scenario wherein the individual forest types are accounted.
This paper identifies and assesses potential brackishwater aquaculture areas on a regional/provincial perspective using geographic information systems (GIS) and multicriteria technique on three sites in the Philippines - Lingayen Gulf area, San Miguel Bay in Bicol region and Negros Occidental. Criteria used cover biogeophysical factors, i.e. soil texture, elevation, land use, physiography and socioeconomic components like settlements, ongoing economic activities other than aquaculture. Some limitations of the study with respect to the use of GIS and the study sites are discussed.
B:RUN is a low-level GIS software designed to help formulate options for the management of the coastal zone of Brunei Darussalam. This contribution presents the oil spill simulation module of B:RUN. This simple module, based largely on wind and sea surface current vector parameters, may be helpful in formulating relevant oil spill contingency plans. It can be easily adapted to other areas, as can the B:RUN software itself.
