This article introduces the rationale and the brief review of the content of the selected papers from the International Symposium “Ecohydrology for sustainable water ecosystems and society in Ethiopia” held on 18th-21st of November 2009 in Addis Ababa, Ethiopia” organized by the European Regional Centre for Ecohydrology under the auspices of UNESCO and the Ministry of Water and Energy of Ethiopia, financed by Ministry of Foreign Affairs of the Republic of Poland – within the Polish Aid Programme. The major criterion of papers selection, above scientific quality, was the perspective of use of the information and knowledge provided in their content to improve the sustainability of water, ecosystems and society, for further development of the wisdom and competences applying the theory of Ecohydrology – one of the priorities of the International Hydrological Programme of UNESCO – as a framework.

This study introduced the spatial pattern of PCDD, PCDF and dl-PCB concentration in the sediments of Ethiopian small river-lake system. Among the analyzed samples the highest contamination was observed in the lake littoral (222.11 ng kg-1 d.w.). The lowest concentration was noted at the outflow from the lake (26.65 ng kg-1 d.w.). The WHO-TEQ concentrations showed decreasing trend along the river-lake system with highest value in the inflow (2.32 ng TEQ kg-1 d.w.) and the lowest at the outflow (0.55 ng TEQ kg-1 d.w.). The concentration of PCDD, PCDF and dl-PCB in the lake causes diseases among local population and prevents of use of water resources except from the outflow. Moreover the lake persistence and its ecosystem services provided for the local community were endangered by erosion of land and nutrient load from pastoral landscape, which could generate toxic algal blooms. For reversing the lake pollution the ecohydrological systemic solutions which integrated methodology to prevent all those threats to sustainable water and ecosystems was designed and implemented.
