Managing the Resilience of Lakes: A Multi-agent Modeling Approach Ecology and Society
Janssen, Marco A; Indiana University; maajanss@indiana.edu; Carpenter, Stephen R; University of Wisconsin-Madison; srcarpen@wisc.edu.
We demonstrate an approach for integrating social and ecological models to study ecosystem management strategies. We focus on the management of lake eutrophication. A model has been developed in which the dynamics of the lake, the learning dynamics of society, and the interactions between ecology and society are included. Analyses with the model show that active learning is important to retain the resilience of lakes. Although very low levels of phosphorus in the water will not be reached, active learning reduce the chance of catastrophic high phosphorus levels.

Implications of climate change on the management of Rift Valley lakes in Kenya. The case of lake Baringo OceanDocs
Ngaira, Josephine K..
Climate patterns of the World became very variable during the last half of the twentieth century. Causes of this variability/change have been identified as: Sun Spot activity, ozone depletion, decline in the solar beam, with the more pronounced especially in Africa being Increased atmospheric carbondioxide, and albedo change due to anthropogenic factors. The most affected weather elements by the above mentioned factors particularly in the tropics are Rainfall and Temperature, and the climatic environments most affected by the named weather elements are the arid and semi-arid lands which are already moisture constrained. The rift valley in Kenya, where most of the lakes are located experience Arid and Semi-Arid climate. The lakes located in this region are...

The physical limnology of Winam Gulf and Rusinga Channel of Lake Victoria during April-May and August of 2005 OceanDocs
Alexander, R.; Antenucci, J.P.; Attwater, G..
Winam Gulf (Kenya) is a large (surface area ~ 1400 km2) and shallow (<20 m) bay of northeastern Lake Victoria with only one connection to the open lake through Rusinga Channel. To understand the exchange dynamics between Winam Gulf and the offshore waters of Lake Victoria and the hydrodynamics of the region, field studies were carried out from Apr. 22-May 4 and Aug. 5-16 of 2005. A meteorological station (shortwave, total radiation, air temperature, relative humidity, wind speed and direction), thermistor chain (0.75m vertical resolution) and ADCP (40 cm vertical resolution) were deployed in Rusinga Channel in a depth of 20m. Similarly, at an offshore station in northeastern Lake Victoria another thermistor chain was deployed in a water depth of 40 m...
