Treasure troves of life on Earth, and the Lungs of the Earth

Wetlands are treasure troves of the ecosystem, with about 20% of the life on Earth inhabiting in it. As they also reserve 20% of the total carbon; they are also called "the Lungs of the Earth." . However, since 1900, 64% of the wetlands worldwide have been destroyed by fire, destructing the ecosystem; furthermore, the livelihood of 1 billion people in fishery, agriculture and handicraft industries that depend on the wetlands for survival is being threatened.

The Ramsar Convention, international treaty for conservation and protection of the wetlands

The international community has adopted the Ramsar Convention in order to conserve the fast-disappearing wetlands. In order to protect the ecosystem, the parties to the Convention designate as Ramsar sites the wetlands that are important for conservation. Furthermore, the governments around the world have designated February 2nd as the World Wetlands Day in order to celebrate the day that the Ramsar Convention was adopted, which was February 2, 1971.

Technology to create and restore wetland ecosystems using native waterside plants

Environmental R&D technology for wetland management and restoration (1)

Technical Overview

  • Developed a technology to both create and restore a wetland ecosystem using the ecological characteristics unique to endangered plants marsh trefoil and cowbane (Cicuta virosa). and native waterside plants, Oriental penthorum (Penthorum chinense pursh) and bur reed.

Strengths compared to the existing technologies

  • Easy to construct and maintain/repair; can restore ecological axes that have been severed by concrete revetment.
  • Can be used for local stream management by federal and local governments, for constructing a habitat for endangered plants and native plants, and for creating wetlands and developing the waterside areas

Company Information

Korea Urban Forestation Co., Ltd, www.biotope.co.kr, +82-2-414-1117

Key Performance

As the no. 1 company with a green rooftop technology in Korea, provides planning, designing and technology for planting and building the foundation for greenification.

Environmental R&D technology for wetland management and restoration (2)

Technical Overview

  • Invented a flow-shift module in the wetlands and yellow soil media, baked at 900℃, and developed an artificial wetland system equipped with flow-shift module using the yellow soil media as the main component.

Strengths compared to the existing technologies

  • Higher competency to remove contaminants than non-flow diverted wetlands
  • Can be applied directly to the contaminated streams

Company Information

Dong Ha Co., Ltd., www.dong-ha.com, +82-31-529-2026

Key Performance

As a leading company in natural stream water quality management technology, developed a flow-diverted bed system (FDB) and applied the system to streams in local communities in Korea.
