Land cover in the Mekong Delta has changed dramatically since Vietnam was unified in 1975. Change has been particularly dramatic since the 1990s when government instructions led to the mass conversion of mangroves to shrimp ponds. Despite efforts to slow the loss of mangroves, the process continues. To support a range of projects on land and water use in the Mekong Delta, IUCN collaborated with Vietnam's Space Technology Institute to classify land cover change using SPOT multi-spectral images for 2004-05 and 2009-10. The results show significant changes over this 5-year period with important implications for land use planning and disaster risk reduction. The classified images will be posted online for public access.
