Connection between health of wetlands and humans in focus   The Creston Valley is located on the floodplain of the Kootenay River, at the south end of Kootenay Lake in the Province of British Columbia, and is managed by the Creston Valley Wildlife Management Authority (CVWMA) and the Canadian Wildlife Service (CWS).

Because more than 25% of the world’s wetlands are located in Canada, Earth Observation can play a vital role in fulfiling this objective.   Water quality parametres, Greater St Lucia Wetland Park, South Africa. Chlorophyll-a relative concentration values: the colour scale over the wetland ranges from the lower concentration values in dark blue to the maximum concentration values in red.   This change-detection map shows significant loss of forested areas over Lake Bogoria, Kenya.
