Abstract

Lake Tana is valuable for many people, including the communities who live around the lakeshore, those living on islands and close to the Blue Nile River, which flows from it. The area has been identified as a region for irrigation and hydropower development, which are vital for food security and economic growth in Ethiopia. This report presents findings from an integrated multidisciplinary study that was conducted to investigate the implications of this development. The study comprised three components: i) an environmental flow evaluation; ii) a stakeholder analysis of the impact of current infrastructure and water management; and iii) computer modeling of future water resources development. The study found that existing water resources development, for hydropower generation, has modified flows downstream of the lake, reduced water levels of the lake and significantly decreased flow over the Tis Issat Waterfall. Interviews with stakeholders indicate that the changes have benefited some people but have adversely affected others. Future development will exacerbate pressure on the lake. If all the planned development occurs, the mean water level of the lake will drop by 0.44 meters (m), and the average surface area will decrease by 30 square kilometers (km²) (i.e., 1%) and up to 81 km² (i.e., 2.6%) during some dry seasons. There will be prolonged periods of several years during which water levels will be much lower than they would be naturally. If environmental flow requirements (estimated to average 862 Mm³y-1) are maintained in the reach containing the Tis Issat Waterfall, the mean water level of the lake will reduce by a further 0.37 m and the average lake area will reduce by an additional 26 km². Without careful management these changes are likely to have severe ecological and social consequences. Hard choices must be made about how the water is best utilized. It is important that all stakeholders, including local people, are involved in the decision-making process and benefit from investments. [ABSTRACT FROM AUTHOR]

Abstract

Irrigation development has been identified as an important tool to stimulate economic growth and rural development, and is considered as a cornerstone of food security and poverty reduction in Ethiopia. While a lot of effort is being exerted towards irrigation development, little attempt is being made to quantify the contribution of irrigation to national income. This study is an attempt in that direction by quantifying the actual and expected contribution of irrigation to the Ethiopian national economy for the 2005/2006 and 2009/2010 cropping seasons using the adjusted net gross margin analysis. Our results show that irrigation generates an average income of approximately US$323/hectare (ha) under smallholder-managed irrigation systems compared to an average income of US$147/ha for rainfed systems. This indicates that, after accounting for annual investment replacement cost, the adjusted gross margin from irrigation is 219.7% higher than the gross margin from rainfed agriculture. The gross margin from medium- and large-scale systems was calculated to be US$400/ ha and US$1,308/ha, respectively. Based on our calculations, irrigation contributed approximately 5.7 and 2.5% to agricultural Gross Domestic Product (GDP) and the overall GDP, respectively, during the 2005/2006 cropping season. By the year 2009/2010, the contribution of irrigation to agricultural GDP and overall GDP is estimated to be approximately 9 and 3.7%, respectively. After relaxing some of the underlying assumptions, the future contribution of irrigation to agricultural GDP rises to approximately 12% while the contribution to overall GDP will be approximately 4%. To realize these outcomes, besides the obvious task of developing the planned irrigation infrastructure, there is a need to: i) improve the provision of agricultural inputs including high-value crops, ii) improve the performance of the agricultural extension system to support irrigation to enhance efficiency and productivity, iii) improve market access conditions and marketing infrastructure, and iv) improve the management of schemes to increase efficiency at all levels. Additional policy implications for cost recovery and sustainability of irrigation investment are drawn. [ABSTRACT FROM AUTHOR]
