PROXIMITY TO WATER SOURCES

Over the past decades, there has been an increasing nutrient enrichment and greening in northern Lake Victoria. Population upsurge is also associated with the unethical discharge of domestic and industrial wastes and consequently increased nutrient loads that enhance proliferation of harmful cyanobacterial blooms. Cyanobacterial harmful algal blooms (CyanoHABs) in eutrophic aquatic systems such as Lake Victoria have environmental, social, and economic impacts. These effects range from acute morbidity and mortality of biota to economic impacts across the world..

IN-SITU MESOCOSMS EXPERIMENTATIONS

Mesocosm experiments in the Napoleon Gulf northern Lake Victoria (Jinja) have tested the feasibility of such approaches on the lake, with the operational facilities of NaFIRRI. These allowed for the monitoring of nutrient and chlorophyll-a, the microbial contaminants other than cyanobacteria and their toxins? Additionally we managed to evaluate the evolution of biomass and phytoplankton diversity if nutrient supply is continuous as likely if human populations increase on the shores of Lake Victoria.

SURFACE GREENING OF WATER

Cyanobacteria, also known as blue-green algae, cyanobacteria have caused a number of water quality issues including toxin production. Like any other organism, underfavourable conditions of growth resources, cyanobacteria multiply rapidly thereby causing "blooms". The blooms can proliferate due to increase in nutrient discharge from catchments and around major towns and cities.

YSI-EX02 CALIBRATION EQUIPMENT

The EXO2 sonde is a multiparameter instrument that collects water quality data. This allowed the continuous field water quality measurements in Napoleon Gulf, Murchison Bay and Mesocosm experimentations.
