With growing expectations for economic cooperation between the two Koreas, there is much interest in participating in the construction of infrastructure in North Korea. In particular, water and sewage infrastructure is the four major social infrastructures in addition to housing, transportation, electricity and telecommunications. North Korea is known to have severe water pollution and ecosystem destruction in major rivers, water pollution and soil pollution in mining areas are serious, and water and sewage infrastructures in cities other than Pyongyang are known to be weak. Preemptive investment in water supply and drainage in North Korea is the foundation for securing the quality of life of the North Korean and is the foundation of public health and industry. It is a leading investment to reduce the cost of unification and is a new growth engine for the water reloded industry. In this study, we proposed a plan to exchange and cooperate in water environment for building water infrastructure of North Korea by examining the data related to water quality, water resources, water disaster, related legal system and human resources exchange situations in North Korea.

This study explains relationship of low-carbon green growth among China, ROK, and DPRK. How this and inter-Korean cooperation in energy & environment were interrelated will also analyzed here. Low-carbon green growth is indispensable to sustaining industrial and economic development of these three nations. It seems as if green growth was last on the list of concerns of Western politicians. But now China and South Korea as well as some Western countries were keen to tell the world that they have a strong interest in green growth. 'Green growth' and 'sustainability' are the words on the lips of people all over the world. ROK hosted the Group of 20 Summit and the government's strong drive for green growth reshaped Korea's position on the global map. With the help of President Lee Myung-bak and world leaders, the Global Green Growth Institute has recently turned into an official international organization. Furthermore, the president pledged to establish a Global Green Technology Award and raise government financial assistance to promote the green growth era and motivate talented minds. South Korea is willing to help DPRK with green industry, even for future unified Korea.

Scientific analysis and inter-Korean cooperation are needed to reduce North Korea’s environmental pollution and deforestation. Many efforts to reduce North Korea’s environmental issue have a fundamental weakness because they are generally influenced by internal and political conditions. To overcome such a weakness, two approaches may be effective; the first is to use new technology such as Google Earth and the second is to build collaborative governance that is invulnerable to political conditions. This study focuses on building collaborative governance models based on Google Earth data investigation, a previous research’s release of Google Earth database, and literature review of North Korea’s environmental issues. This research’s results are as follows. First, North Korea’s industrial regions suffer from environmental pollution and many other regions experience severe deforestation according to Google Earth-based spatial images. Second, we can discern environmental pollution such as air pollution, water pollution, soil pollution, and deforestation using Google Earth-based spatial image. In reality, we are able to identify deforestation and partially soil pollution with Google Earth-based spatial image. Third, there are different environmental problems among North Korea’s local regions. South Korea has to prepare and plan various collaborative governance models depending on North Korea’s local needs on environmental problems.
