Common waters and private lands: Distributional impacts of floodplain aquaculture in Bangladesh

Journal Articles & Books
December, 2008
Bangladesh

Aquaculture continues to diversify and develop rapidly in Bangladesh. A major change has taken place in parts of Bangladesh due to the growth of floodplain aquaculture (FPA) projects. FPA involves the enclosure by the landholders of parts of the floodplain through the creation of embankments and sluice gates. The enclosed water body is stocked with fish seed and the benefits are distributed amongst those who own land in the impounded area.

Effects of Land Use Changes on the Ecosystem Service Values of Coastal Wetlands

Mexico

Changes in the coastal landscape of Southern Sinaloa (Mexico), between 2000 and 2010, were analyzed to relate spatial variations in wetlands extent with the provision and economic value of the ecosystem services (ES). Remote sensing techniques applied to Landsat TM imagery were used to evaluate land use/land cover changes while the value transfer method was used to assess the value of ES by land cover category. Five wetland types and other four land covers were found as representative of the coastal landscape.

Reducing reservoir impacts and improving outcomes for dam‐forced resettlement: experiences in central Vietnam

Journal Articles & Books
December, 2014
Vietnam

The present study focuses on the growing problem of the impacts of human displacement resulting from hydropower dam construction, within the context of the integrated lake basin management of dam reservoirs. Dam‐forced displacement and resettlement can pose severe challenges to the environmental, economic and social sustainability of a reservoir basin.

Genetic improvement for the development of efficient global aquaculture: A personal opinion review

Journal Articles & Books

Norway

It has been exciting to follow the rapid development of aquaculture production in Norway, and internationally, since 1971. As an animal breeder I am particularly impressed with the genetic gain obtained for growth rate, and also for disease resistance in several aquatic species, which is five to six times higher than what has been achieved in terrestrial farm animals. This is illustrated in five selected projects I have been involved in. The sad story is, however, that only less than 10% of the world's aquaculture production is based on genetically improved stocks.

Land use, land cover changes and coastal lagoon surface reduction associated with urban growth in northwest Mexico

Journal Articles & Books
December, 2003
Mexico

Coastal land use and land cover changes, emphasizing the alterations of coastal lagoons, were assessed in northwest Mexico using satellite imagery processing. Supervised classifications of a Landsat series (1973–1997) and the coefficients Kappa (K) and Tau (τ), were used to assess the area and verify the accuracy of the classification of six informational classes (urban area, aquatic systems, mangrove, agriculture, natural vegetation, and aquaculture). Pixel-by-pixel change detection among dates was evaluated using the Kappa Index of Agreement (KIA).

Predicted impact of the sea-level rise at Vellar–Coleroon estuarine region of Tamil Nadu coast in India: Mainstreaming adaptation as a coastal zone management option

Journal Articles & Books
December, 2012
India

Low-lying coastal areas are more vulnerable to the impacts of climate change as they are highly prone for inundation to SLR (Sea-Level Rise). This study presents an appraisal of the impacts of SLR on the coastal natural resources and its dependent social communities in the low-lying area of Vellar–Coleroon estuarine region of the Tamil Nadu coast, India. Digital Elevation Model (DEM) derived from SRTM 90M (Shuttle Radar Topographic Mission) data, along with GIS (Geographic Information System) techniques are used to identify an area of inundation in the study site.

Implications of floodplain aquaculture enclosure

Journal Articles & Books
December, 2012
Bangladesh

In Bangladesh, extensive common pool fisheries exist in the wet season on private lands in the floodplains. This study investigated the trend in year-round enclosure of these seasonal commons for private aquaculture and the impacts of this practice. The floodplain area enclosed for aquaculture was found to be growing at 30–100% a year. Enclosures are organised by individual landowners, informal groups or companies that lease in land. Aquaculture in enclosures produces more fish than capture fisheries, but input costs are high.

Appraisal of land use/land cover of mangrove forest ecosystem using support vector machine

Journal Articles & Books
December, 2014
India

Human activities in many parts of the world have greatly changed the natural land cover. This study has been conducted on Pichavaram forest, south east coast of India, famous for its unique mangrove bio-diversity. The main objectives of this study were focused on monitoring land cover changes particularly for the mangrove forest in the Pichavaram area using multi-temporal Landsat images captured in the 1991, 2000, and 2009.

This report was prepared by the World Bank in partnership with the Livelihoods and Food Security Multi-Donor Trust Fund (LIFT). Both the World Bank and the LIFT are actively involved in supporting Myanmar’s agriculture sector given its significance in poverty reduction and food security, and they both consider the lack of reliable farm data to be a significant constraint to designing effective programs and policies. This report fills some of the data gaps. In addition to presenting the collected data, the report offers the first analysis of these data.

To meet carbon emissions targets, more than 30 countries have committed to boosting production of renewable resources from biological materials andconvert them into products such as food, animal feedand bioenergy. In a post-fossil-fuel world, an increasingproportion of chemicals, plastics, textiles, fuels and electricity will have to come from biomass, which takesup land. To maintain current consumption trends theworld will also need to produce 50–70 percent more foodby 2050, increasingly under drought conditions and onpoor soils.

To further develop and finalize the Fishery Performance Indicators (FPIs) for scaling up to the Bank's entire fisheries portfolio, a number of specific pilots and case studies have been conducted. This report provides an overview of the FPIs, and a summary of two case studies in its application, the blue swimming crab (BSC) fisheries in Indonesia and the Philippines. A comparative analysis with an Icelandic lobster fishery is conducted as a benchmark, as the Icelandic lobster fishery is also export oriented and has been recognized as a well-managed fishery.
