Environmental impact of agriculture on the coastal region of Sierpe, Costa Rica
The impact of sewage and agricultural runoff on the water quality of the Térraba Sierpe National Wetlands, on the Pacific coast of Costa Rica, has been evaluated using data acquired by DESIS. In addition to the RGB image (the visible range of the electromagnetic spectrum; image 1), the evaluations for suspended matter (image 2), dissolved organic material (referred to as yellow matter or Colored Dissolved Organic Matter (CDOM); image 3) and phytoplankton (image 4) are shown. Since phytoplankton is the first stage of many food chains, it is important to know how this part of the local ecosystem is impacted by agricultural fertilisation.
