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"
The third research year out of the planned five, is mainly directed at the following priorities:
- 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;
- Supervision of project realization, including preparation of information and materials necessary for implementation of activities in Ethiopia (see below);
- Preparation of publications, reports and presentations.
- Elaboration of concepts for ecohydrological system solutions
- Concept for ecohydrological system solutions for urban areas
- Improving sanitation, wastewater treatment of municipal, hospitals, industrial wastes;
- 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.
- 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.
- 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;
- Identification of the key factors effecting resilient and sustainable agriculture;
- Elaboration of guidelines for design of landscape patches in Tana Lake basin.
- Demonstration projects
- Sequential biofiltration system (SBFS) for point sources in rural areas
Challenges to be addressed:
- Reducing the impact of rural settlements on stream/river water quality by construction of SBFS;
- 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.
- Conversion of sediments for SBFS and organic sediments into bioenergy and food production
Challenges to be addressed:
- Use of the sediments collected in the SBFS and pre-reservoirs for eroded soil restoration (using phytotechnology) and bioenergy production;
- Use of biodegradable geofibers for land erosion control and biofarming
Challenges to be addressed:
- Geofibres for stabilization restored erosion diches by sediment from reservoirs and sludge from SBFS;
- Shortening the time for ecological succession of the degraded land by application pf geofibers with seeds of local plants;
- Recycling of natural fibres by using cotton/wool waste material for geofibres technology transfer
