Using Satellite Imagery to Combat weevil disease Outbreaks in Pine Forests

Using Satellite Imagery to Combat weevil disease Outbreaks in Pine Forests

Implemented by the International Cooperation and Development Fund (TaiwanICDF), the Capability Enhancement in Using Geographic Information Systems (GIS) in Central America project team in El Salvador provided high resolution satellite imagery to the El Salvadorian government on September 13 to assist our partner country in tracing and monitoring the spread of insect pests (weevil disease) in the pine forests, and to elaborate a pest control and prevention plan. Data analysis found that more than 300 hectares of forest were affected by the outbreak of weevil disease.

In 2009, the TaiwanICDF and Center for Space and Remote Sensing Research, National Central University collaborated on the use of GIS for environmental protection in Nicaragua. Witnessing the remarkable results of this project, Honduras requested to participate in 2011 and the project was expanded to cover the Central American region. As the weevil disease outbreaks spread to the borders of Honduras and El Salvador, the El Salvadorian government joined in 2013 in hopes that the technical assistance in using remote sensing imagery analysis can help the country control the spread of insect pests.

The objective of the Capability Enhancement in Using Geographic Information Systems (GIS) in Central America, a regional project, is to use GIS technology to monitor national land use and natural reserves. The project is designed to assist partner countries to respond more effectively to natural disasters and reduce the impacts and losses caused by environmental threats. Currently, the technical assistance in this project includes providing satellite imagery and technical advice on water quality monitoring in Nicaragua, environmental management in Honduras and national land use planning in El Salvador. In the future, the TaiwanICDF will continue to apply GIS technology in environmental protection and climate change to support our partner countries in Central America.
