Zielsetzung und Themenschwerpunkte (Objectives and Key Themes)

This thesis investigates the invasion rate of Prosopis juliflora, an invasive species, in the Amibara District of Ethiopia's Afar Regional State, focusing on land use/land cover changes from 1973 to 2004. It aims to analyze the rate of invasion using multi-temporal Landsat imagery data, identify the impacts of the invasion, and explore management techniques to mitigate its spread. The study aims to fill information gaps from image analysis through field surveys.

• The invasion rate of Prosopis juliflora in Amibara District.
• The impacts of P. juliflora invasion on the environment, livelihood, and human health.
• The effectiveness of various management techniques in controlling the spread of P. juliflora.
• The role of community involvement and stakeholder collaboration in managing the invasion.
• The potential for sustainable use of P. juliflora as a resource.
