Ethiopia and the Eastern Nile Basin
Arsano, Yacob
Ethiopia is the main source of the Nile River, and the country urgently needs water for irrigation and hydro-electric power development. To-date, however, Ethiopia is the country in the Eastern Nile basin that uses the least amount of water from the Nile run-off. There is no basin-wide agreement on the utilization and management of the water resources of the Nile Basin. Unilateral planning and implementation approaches have hindered the possibilities of cooperation and coordinated development. On the national level, economic and institutional capacities are also limited. Past initiatives as well as the current Nile Basin Initiative (NBI) are outlined regarding how far these dilemmas are dealt with. The paper ends with suggestions on how to deal with open questions and lessons learned from the ongoing NBI process. Aquatic Sciences 2005, (67): pp. 15-27. Available for purchase from: SpringerLink
Dangerous Divisions: Irrigation Disputes and Conflict Transformation in the Ferghana Valley
Bichsel, Christine
PhD Thesis, University of Bern, Switzerland "The present study focuses on irrigation disputes and 'conflict transformation' in Central Asia. It analyses three projects by international and bilateral donors who share common approach to transforming irrgation conflicts in the Ferghana Valley. [...] Three major research foci guide this study. First, it addresses the environment-conflict nexus. It explores the relationship between irrigation and the occurence of inter-group conflict. Second, the thesis examines the prescriptive approach of 'conflict transformation'. It focuses on the norms and values that construe conflict and its mitigation. Third, the research addresses the issue of power. It examines both conflicts and interventions studied for their embeddedness in power relations." For further information, please contact the author

Towards a System Dynamics Framework for Understanding Interactions of Head- and Tail-Users in Irrigation Systems in Kyrgyzstan
Gallati, Justus
Conference paper for the 24th International Conference of the System Dynamics Society July 23-27, 2006 Nijmegen, The Netherlands The paper outlines a conceptual framework for a dynamic model for collective irrigation management. Furthermore a preliminary causal loop diagram for the interaction of upstream- and downstream users is presented. The study builds on the results of a workshop with local participants in Kyrgyzstan on sustainable regional development and on the literature on collective resource management. Download
Integrated faecal sludge treatment and recycling through constructed wetlands and sunflower plant irrigation
Koottatep, Thammarat
"Faecal sludge (FS) from the on-site sanitation systems is a nutrient-rich source but can contain high concentrations of toxic metals and chemicals and infectious micro-organisms. The study employed 3 vertical-flow CW units, each with a dimension of 5×5×0.65 m (width×length×media depth) and planted with cattails (Typha augustifolia). At the solid loading rate of 250 kg total solids (TS)/m2.yr and a 6-day percolate impoundment, the CW system could achieve chemical oxygen demand (COD), TS and total Kjeldahl nitrogen (TKN) removal efficiencies in the range of 80–96%. A solid layer of about 80 cm was found accumulated on the CW bed surface after operating the CW units for 7 years, but no clogging problem has been observed. The CW percolate was applied to 16 irrigation sunflower plant (Helianthus annuus) plots, each with a dimension of 4.5×4.5 m (width×length). In the study, tap water was mixed with 20%, 80% and 100% of the CW percolate at the application rate of 7.5 mm/day. Based on a 1-year data in which 3 crops of plantation were experimented, the contents of Zn, Mn and Cu in soil of the experimental plots were found to increase with increase in CW percolate ratios. In a plot with 100% of CW percolate irrigation, the maximum Zn, Mn and Cu concentrations of 5.0, 12.3 and 2.5 mg/kg, respectively, were detected in the percolate-fed soil, whereas no accumulation of heavy metals in the plant tissues (i.e. leaves, stems and flowers) of the sunflower were detected. The highest plant biomass yield and oil content of 1000 kg/ha and 35%, respectively, were obtained from the plots fed with 20% or 50% of the CW percolate."
