The Graeme Hall Swamp is linked to the St. Lawrence Lagoon and is the last remaining coastal wetland in Barbados. The wetland has been designated as a Natural Heritage Conservation Area and has also been established as one of two Caribbean Coastal Marine Productivity Programme (CARICOMP) monitoring sites in Barbados. The Graeme Hall Watershed, located in the south of Barbados, spans 1,156 acres. The most significant element of this watershed is the Graeme Hall Swamp.
The Upper Mur River is considered as one of the most ecologically valuable rivers of Austria due to the natural reproduction for the Danube salmon. The systematic regulation of the river began at the end of the 19th century, distributaries were cut off and large areas were drained in order to intensify agricultural land use. Restoration measures started in 1997 in the area of the Upper Mur and the “Grenzmur”. Various projects facilitated the renaturation of more than 22 km both in the upper course and the Slovenian border section of the river. A policy issue highlighted by the project is the importance to reconcile key needs for nature conservation with demands for renewable energy generation from small hydro power plants.
The Chilika Lagoon was subjected to environmental degradation. Action was taken by the Chilika Development Authority through the application of GIS and remote sensing tools for monitoring and assessment of the lagoon, resulting in significant improvement of the ecological health of the lagoon. The key lesson learnt is how a clear understanding of the coastal process and the river basin is essential for restoration of a coastal wetland.
In the Danube hydrographic basin, agricultural practices continue to be the main source of water pollution. A pilot project “Best Agricultural Practices” was initiated focusing on e.g. nutrient management, conservation tillage and manure management. Awareness campaigns were initiated, training and education of farmers were emphasised. The key lesson is that these projects should be complimented by other technical and investment measures.
China is faced with significant costs regarding floods and degradation of ecological conditions in the Yangtze River basin. As a response, the application of Ecosystem Function Conservation Areas approach has been initiated not only to increase water retention capacity and reduce sediment loads, but also to provide benefits in biodiversity, carbon sequestration and sustainable land management. The key lesson is that success is easier to achieve with positive natural and political conditions.
