The water hyncinth problem in Uganda
Water hyacinth is native to countries in South America such as Brazil where it occurs in balance with nature controlled basically by natural enemies and seasonal fluctuation in water levels. The water weed has however been introduced to many countries throughout the tropics and sub-tropics, mainly by man in admiration of its beautiful flower. In the introduced range water hyacinth grows and spreads extremely rapidly to turn into one of the most noxious water weeds known. In Africa the water weed appears to have been introduced first in Egypt late in the 19th Century and later in South Africa. Water hyacinth has since gained entry into many countries in west, east and southern Africa.
