Project 944/2010 and 23/2011 financed by the Ministry for Foreign Affairs Polish Aid Programme for the year 2010 and 2011 "Implementation of Ecohydrology - a transdysciplinary science - for integrated water management and sustainable development in Ethiopia"

REASERCH PERFORMED IN 2010

The third research year out of the planned five, is mainly directed at the following priorities:

IN POLAND

  1. Laboratory analysis
    • Analysis of physicochemical parameters(nitrogen and phosphorus, chlorophyll a, ect);
    • 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 toxic congners of PCDD, PCDF and dl-PCB;
  2. Supervision of project realization, including preparation of information and materials necessary for implementation of activities in Ethiopia (see below);
  3. Preparation of publications, reports and presentations.

      • Improving human health;
      • Assuring sustainability of the developed solutions by linking environmental systems with income generation e.g., use of municipal sewage for bioenergy/biogas production;
      • providing implications for legislation.
    2. Early Warning System for toxic algal blooms
      • Development methodology reversing lake;
      • Mitigating human health risks resulted from toxic algal blooms;
      • Establishing methodology and a laboratory for early warning system for detecting toxic algal blooms and industrial pollution risks.
    3. Concept of introduction of landscape patches, buffering zone and multifunctional land-water ecotones for food production, water retention and reduction of N and P loads
      • Typology of landscapes in Tana Lake basin;
      • Estimation of the heat budget in the landscape structure and water balances for different types of landscape from the perspective of climate change;

  2. Demonstration projects
    1. Sequential biofiltration system (SBFS) for point sources in rural areas
      Challenges to be addressed:
      1. Reducing the impact of rural settlements on stream/river water quality by construction of SBFS;
      2. Construction in agriculture landscape system for water quality protection by separation of sites of animal watering of the river and manual collection in postural landscape.
    2. Conversion of sediments for SBFS and organic sediments into bioenergy and food production
      Challenges to be addressed:
      1. Use of the sediments collected in the SBFS and pre-reservoirs for eroded soil restoration (using phytotechnology) and bioenergy production;
    3. Use of biodegradable geofibers for land erosion control and biofarming
      Challenges to be addressed:
      1. Geofibres for stabilization restored erosion diches by sediment from reservoirs and sludge from SBFS;
      2. Shortening the time for ecological succession of the degraded land by application pf geofibers with seeds of local plants;
      3. Recycling of natural fibres by using cotton/wool waste material for geofibres technology transfer
