  • Wastewater irrigation of Salix Plantations - Hedemora Energy

    Type: 
    Product
    Objective:

    The largest and northern most full-scale system for wastewater irrigation of Salix plantations in Sweden.
    The local community in Hedemora has long experience in producing biofuel from Salix plantations. The cooperation between Hedemora Energi AB and local farmers has resulted in irrigation of 75 acres of Salix Plantations. The local farmers in the project are guaranteed to sell their biofuel to the local municipal heating plant. As a result the project is contributing to the local production and consumption.

  • Artificial wetlands in Trosa

    Type: 
    Product
    Objective:
    Technology:

    Since 2003 the waste water from the town of Trosa (about 4500 citizens) has been treated in artificial wetlands, after the basic treatment in the sewage plant. Thanks to the wetlands the Trosa river and the town bay have been spared from eutrophicating substances (plant nutrients) as well as contagious substances (pathogenes). Besides the value of purifying the water, the wetlands are a popular recreation area. The wetlands are used for education and many study visits are made here.

  • Constructed wetlands for water treatment

    Type: 
    Technology
    Sectors:
    Objective:

    Description

    Constructed wetlands make use of the natural purification processes of vegetation, soils and microbes to remove contaminants from discharge. Uses of constructed wetlands for water purification include applications in industrial wastewater and municipal wastewater and storm water treatment. This relatively low-cost technology improves water security and access, making it important for climate change adaptation. Additionally, green spaces created by wetlands produce habitats for wildlife and may improve recreational value.

  • Floating agricultural systems

    Type: 
    Technology
    Sectors:
    Objective:
    Approach:

    Floating agriculture is a way of utilising areas which are waterlogged for long periods of time in the production of food. The technology is mainly aimed at adapting to more regular or prolonged flooding.

    The approach employs beds of rotting vegetation, which act as compost for crop growth. These beds are able to float on the surface of the water, thus creating areas of land suitable for agriculture within waterlogged regions. Scientifically, floating agriculture may be referred to as hydroponics. In Bangladesh, it has regional names such as baira, geto, dhap and bed.

  • Providing low-budget estimations of carbon sequestration and greenhouse gas emissions in agricultural wetlands.

    Type: 
    Publication
    Publication date:
    Objective:

    The conversion of wetlands to agriculture through drainage and flooding, and the burning of wetland areas for agriculture have important implications for greenhouse gas (GHG) production and changing carbon stocks. However, the estimation of net GHG changes from mitigation practices in agricultural wetlands is complex compared to dryland crops. Agricultural wetlands have more complicated carbon and nitrogen cycles with both above- and below-ground processes and export of carbon via vertical and horizontal movement of water through the wetland.
