The construction of dams in Africa is often associated with adverse malaria impacts in surrounding communities. However, the degree and nature of these impacts are rarely quantified and the feasibility of manipulating reservoir water levels to control mosquito breeding has not been previously investigated in Africa. This report describes entomological and epidemiological studies conducted around the Koka Dam and Reservoir in Ethiopia. The research findings confirm the role of the reservoir in increasing malaria transmission and provide evidence that there is potential to use dam operation in integrated malaria control strategies.

Irrigation development has been identified as a means to stimulate economic growth and rural development in Ethiopia. However, little attempt has been made to quantify the contribution of irrigation to national income. Using data from selected irrigation schemes, representing small, medium and large-scale schemes of modern or traditional typologies; the present coverage and planned growth of irrigation, actual and expected contributions of irrigation to the national economy were quantified following the approach of adjusted gross margin analysis. Our results show that irrigation yields 219.7% higher income compared to the rainfed system while its current and future contribution to agricultural GDP is estimated to be about 5.7 and 12% although irrigation covers about 5 and 9% of the total cultivated land area, respectively.

Seminar paper from the year 2021 in the subject Agrarian Studies, grade: A, Haramaya University (Institute of Technology), course: Seiner Seminar, language: English, abstract: This text deals with the impact of irrigation water use on groundwater environment and soil salinity in Ethiopia. Irrigation systems have been under pressure to produce more with lower supplies of water. Various innovative practices can gain an economic advantage while also reducing environmental burdens such as water abstraction, energy use, pollutants, etc. Farmers can better use technological systems already installed, adopt extra technologies, enhance their skills in soil and water management, tailor cropping patterns to lower water demand and usage, reduce agrochemical inputs and more. Water scarcity has been defined as the point at which the aggregate impact of all users impinges on the supply or quality of water under prevailing institutional arrangements to the extent that the demand by all sectors, including the environment, cannot be satisfied fully.

This thesis explores the impact of water harvesting irrigation development through pond, deep well and shallow well on poverty and livelihood in three districts in Northern Ethiopia. The overall working hypothesis of the thesis is that irrigation development has an impact in improving household welfare and reduces the incidence of poverty. The analysis is based on primary household-level data collected from 602 randomly selected households. To analyses the impact descriptive statistics, poverty profile comparison, and econometrics matching method were used. Key conclusions include: First, households{u2019} access to deep well or shallow well irrigation has a significant impact on poverty reduction through increasing household incomes and consumption and overall family employment. It is also highlighted that access to deep well irrigation has a significant effect in reducing household dependency on food aid. However, the thesis{u2019} finding shows no impact of pond water harvesting irrigation in reducing poverty. Second, the empirical results of the econometric matching shows that access to deep well or shallow well irrigation has a significant effects in increasing the consumption expenditure per adult (welfare level) of beneficiary household. However, the thesis found that pond water harvesting does not seem to have significant effect in increasing welfare level of beneficiary households. Thirdly, the cost benefit analysis revealed that investment in shallow well or deep well irrigation is a financially profitable investment to a farmer. However, the economic analysis and sensitivity analysis suggests that only deep well investment is a profitable option from a public investment perspective. The following major recommendation arises on the basis of the findings: the long-term sustainability of shallow or deep well irrigation depends on wise utilization of groundwater resources. Therefore, it is recommended that policy makers take a mixture of policy and regulatory actions to increase the ground water recharge and promote drip irrigations.

The author looks at the feasibility and potential of instituting small-scale irrigation dams to reduce Ethiopia s dependence on rainfed agriculture and the associated food insecurity. He develops a theoretical framework to assess the welfare implications of irrigation development programs and provides empirical evidence from microdam construction and reforestation projects in northern Ethiopia. The author pays particular attention to health-related costs of establishing small-scale irrigation dams in areas prone to waterborne diseases. While the theoretical analyses imply that the net welfare impacts of irrigation dams cannot be known a priori due to potential health costs, the empirical evidence shows that current agricultural yield and farm profit have increased in villages with closer proximity to the dams than in those more distant. The increased disease incidence due to standing pools of water has, however, led to significant declines in the returns from investment in irrigation water. Households with poor health are less likely to adopt productivity-enhancing as well as resource-conserving technologies, which are crucial for achieving the ultimate goal of sustainable agricultural development. The ensuing sickness has also led to reduction in labor allocation to off-farm activities. The findings underline the importance of weighing beforehand the magnitude of potential economic benefits against health costs of water development programs. The overall evidence, however, suggests that carefully designed irrigation dams could significantly improve agricultural production and food security, particularly in areas where waterborne diseases pose negligible risk to health or can be cost-effectively controlled.

The Craft and Science of Coffee follows the coffee plant from its origins in East Africa to its current role as a global product that influences millions of lives though sustainable development, economics, and consumer desire. For most, coffee is a beloved beverage. However, for some it is also an object of scientifically study, and for others it is approached as a craft, both building on skills and experience. By combining the research and insights of the scientific community and expertise of the crafts people, this unique book brings readers into a sustained and inclusive conversation, one where academic and industrial thought leaders, coffee farmers, and baristas are quoted, each informing and enriching each other. This unusual approach guides the reader on a journey from coffee farmer to roaster, market analyst to barista, in a style that is both rigorous and experience based, universally relevant and personally engaging. From on-farming processes to consumer benefits, the reader is given a deeper appreciation and understanding of coffee's complexity and is invited to form their own educated opinions on the ever changing situation, including potential routes to further shape the coffee future in a responsible manner. Presents a novel synthesis of coffee research and real-world experience that aids understanding, appreciation, and potential action Includes contributions from a multitude of experts who address complex subjects with a conversational approach Provides expert discourse on the coffee calue chain, from agricultural and production practices, sustainability, post-harvest processing, and quality aspects to the economic analysis of the consumer value proposition Engages with the key challenges of future coffee production and potential solutions
