The Impact of Climate Change and Anthropogenic Activities on Fisheries of Lake Logo, South Wello, Ethiopia
A study was conducted in south Wello zone in Ethiopia to see the impacts of climate change on the fish production of lake Logo. Purposive sampling and focus group discussions were used to generate data on the major anthropogenic activities, and perception of the beneficiaries of the lake about climate change. Besides, meteorological variables were obtained from the National Meteorological Agency and its correlation with fish yield of the lake was calculated. Major anthropogenic activities were identified as deforestation, poor soil and water conservation activities, intensified agricultural activities, urbanization, existence of alien invasive plant species, overfishing, illegal fishing, increased number of fishers, irrigation, and flooding. Fish catch of the lake over the years happened to be in a declining trend. Respondents perceived erratic rain, hotter temperature, flooding, drought and erosion. The meteorological data revealed that the mean annual maximum temperature showed an increasing trend, while the mean annual minimum temperature showed a decreasing trend over the years. Rainfall was found to have an erratic nature. Annual maximum temperature and fish yield had a positive relationship. Mean annual minimum temperature and fish yield had negligible relationship. Mean annual maximum rainfall had a positive relationship with fish catch. However, the mean annual minimum rainfall had no relationship with fish yield. It is highly recommended to apply a holistic and balanced environmental management systems so as to save the loss of aquatic biodiversity in the lake.
