Shrimp Farms and Mangroves, Gulf of Fonseca
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
For decades, astronauts on space missions have documented land use changes around the world. In this pair of images, astronauts track the development of shrimp farming along the Honduran coastline of the Gulf of Fonseca between 1989 and 2001. Mariculture, primarily shrimp farming, has become a leading agricultural effort in Honduras. The regional transformation of large tracts of coastal swamps into shrimp farms blossomed throughout the 1990s. The top image was taken with color infrared film in 1989. Dense vegetation, like the coastal mangrove swamps and the forested slopes of Volcán Cosigüina show up as dark red. The bottom image, taken with color visible film by the crew of the most recent Space Shuttle mission in December 2001 shows that hundreds of square kilometers of coastal swamp, primarily in Honduras, have been converted to shrimp ponds. These appear as the light-colored, rectilinear land use pattern. The Honduras shrimp farms were hit hard by flooding after Hurricane Mitch in 1998, and a devastating virus in 1999-2000. It is not known how many of the ponds in this view are still functional. A vigorous debate continues about the sustainability of the shrimp farms and the impacts to the environment and coastal ecosystem due to mangrove clearing and mariculture waste production.
Apart from the shrimp farms, the other prominent feature on these images is the impressive volcano Cosigüina, which erupted explosively in 1859 (the largest recorded eruption in the Western Hemisphere).
