Project "Implementation of Ecohydrology - a transdysciplinary science - for integrated water management and sustainable development in Ethiopia" no 62/2012
The Project is co-financed by the Polish development cooperation programme 2012 of the Ministry of Foreign Affairs of the Republic of Poland

REASERCH PERFORMED IN 2012

The fifth research year was mainly directed at the following priorities:

IN POLAND

  1. Laboratory analysis
    • Analysis of physicochemical parameters(nitrogen and phosphorus, chlorophyll a, etc.);
    • Qualitative and semi-quantitative assessment of toxigenic cyanobacterial strains responsible for production of microcystins;
    • Analysis of microcystins in water and cells by using screening test (ELISA) and liquid chromatography (HPLC);
    • Analysis of concentration and toxicity of dioxins and dioxin-like compounds and heavy metals;
  2. Supervision of project implementation
  3. Preparation of publications, reports and presentations.

IN ETHIOPIA

  1. Activity 1: Efficiency analysis and optimization of the constructed sedimentation-biofiltration systems (SBS) in Asella Biofarm Park and the city of Debre Tabor (Gumera River catchment).
    • Monitoring of the SBSs functioning (collection of water and sediment samples and their analysis in terms of nitrogen, phosphorus, POPs and oxygen concentrations, and conductivity and pH, parameters);
    • Optimization of the SBSs functioning on the basis of the obtained monitoring results;
    • Re-applying of geofibres on the stream banks in order to reduce soil erosion and downstream transport of organic and mineral matter;
  2. Activity 2: Analysis of the dynamics and mechanism of formation of toxic cyanobacterial blooms in two different ecosystems (Lake Tana and Koka Reservoir).
    • Monitoring of physico-chemical parameters of water (temperature, oxygen concentration, pH and conductivity), concentrations of phosphorus, nitrogen and chlorophyll a;
    • Microscopic analysis of biomass and species composition of phytoplankton;
    • Quality assessment and densitometric (semi-quantitative) analysis of the presence of toxic cyanobacterial strains responsible for the microcystins production;
    • Analysis of cyanobacterial hepatotoxins - microcystins- using ELISA screening test
      and high performance liquid chromatography;
    • Evaluation of the toxicity of microcystins by protein phosphatase inhibition (PPIA).
  3. Activity 3: The dynamics of the algae succession (toxic and nontoxic strains) in small fish ponds used as a source of drinking water for farmers.
    • Evaluation whether ponds used for fish production allow for simultaneous use as a source of drinking water through monitoring of nitrogen and phosphorus concentration, and phytoplankton, zooplankton, and fish density and biomass in selected fish ponds.
  4. Activity 4: Restoration of productivity and biodiversity of the landscape in the field complex of pasture-crop-stream (river basin Ribbe)
    • Restoration of the eroded land of the pastures landscape by using geofibres and phytotechnology;
    • Reduction of land overdrying in the agricultural landscapeby creating amid-fieldafforestation(shelterbelts) combined with fruit trees in order to reduce the wind speed, wind erosion (compensation of the lost farming area by production of fruits);
    • Formation of ecotone zones to prevent bank erosion and construction of small rock dams for reduction of bed erosion of the stream.
  5. Activity 5: Improvement of the efficiency and quality of the tilapia (fish) stocking material
    • Developing methodology for using zooplankton in to improve the quality of juvenile fish and their growth rate;
    • Improvement of the energy balance in fish ponds by reducing heat loss during the night.
