Abstract
This study examined the relationship between land-use practices near tributary rivers in South Lake Maracaibo and the appearance of duckweed (Lemna obscura) in the lake. Four rivers were studied: The Mucujepe, Capaz, Guamo and Frio. Eight factors were assessed: rivers, sediments, erosion, soils, fertilizers, water quality, land use activities and vegetation corridors. Satellite images, official cartography, field visits and observations, water samples and personal communication with organizations involved were held to get an accurate and current assessment of the conditions. The study revealed the land-use practices surrounding the Pan-American Zone Rivers contribute to the duckweed blooming in Lake Maracaibo.
