The National Remote Sensing Center is implementing the project “Monitoring landfills by remote sensing technology”. The project is expected to provide useful solutions to strengthen the solid waste management capacity at central and local levels as well as update and improve the operational efficiency of the solid waste information system of the Vietnam Environment Administration.
1. Need an information system for landfill management
According to the report of the Vietnam Environment Administration, Vietnam currently has a very large amount of waste. Most landfills do not have compactors, gas collection systems, leachate treatment, or environmental monitoring systems and are poorly managed, mainly due to lack of funding. This has caused many environmental and health problems and risks, especially in regions with large waste generation and high population densities.
In addition, the number and location of landfills have not been adequately managed. The Vietnam Environment Administration has a database of landfills, but it has not been updated regularly and timely on the status of existing landfills as well as new generated landfills.
Therefore, it is necessary to have a unified management information system on solid waste in which information about landfills and environmentally sensitive areas must be continuously updated with a nationwide scale.
2. Providing completed, continuous and long-term information
According to Mr. Nguyen Quoc Khanh, Director of the National Remote Sensing Center, remote sensing technology with multi-time, wide coverage and good spatial resolution will be an effective tool to monitor landfills nationwide. With the characteristics of remote sensing technology, there is historical data, so information about landfills will be provided from the time of formation, the operation process in the past as well as the present.
Moreover, SPOT6/7 image data covering the whole country allows providing a lot of valuable information for waste management. Remote sensing technology also allows monitoring the progress and status of landfills, factories, and mining areas after they are closed to serve the management of the environmental reclamation and treatment process
In particular, the project is built on remote sensing technology whereby data from the remote sensing image receiving station of the National Remote Sensing Station – the National Remote Sensing Center is capable of providing long-term and continuous data; therefore, the operation of the system and updating information is long-term.
