German scientists have developed a method for monitoring the state of wetlands

German scientists have developed a method for monitoring the status of wetlands based on satellite images, according to a press release from the University of Wurzburg Julius-Maximilian.

Wetlands (wetlands) or wetlands (wetland — the English damp earth) include wetlands, areas of sea and river shores and shallow lakes. In this case, wetlands play a key role in preserving the environment and biodiversity of the planet.

German scientists have chosen as a model to develop a methodology for the region wetlands Linyati in northern Botswana (Africa). Wetlands of forty square at sixty kilometers stretching from the river to the delta Linyati Okavango River, right in the center of the dry savanna.

"We wanted to develop a methodology for continuous measurement of the" pulse "of wetlands in order to in the event of adverse changes was the adoption of adequate measures," — said study leader Dr. Landman Tobias (Tobias Landmann), quoted in the release.

As detailed in the release, the German scientists analyzed the state Linyati according to Terra and Aqua for the period from 2001 to 2010 with a tool MODIS (Moderate Resolution Imaging Spectroradiometer), which detects changes in the area of the green cover of the planet. Based on these data, scientists were able to identify the annual change in the state of wetlands: drying or flooding.

"Pictures revealed that in some years Linyati region becomes drier, and other moisturizing. Overall, from 2001 to 2010, Linyati became more humid," — said in a release.

Meanwhile, according to Landman, which is set to release, to talk about any climatic changes by analyzing satellite images of ten years can not, and should apply the developed methodology for a longer period of time.
