This book addresses challenges and opportunities in the Energy-Water-Environment (EWE) nexus, with a particular focus on research and technology development requirements in harsh desert climates. Its chapters include selected contributions presented during the 1st international conference on sustainable Energy-Water-Environment nexus in desert climates (ICSEWEN-19) held at the Qatar Environment and Energy Research Institute (QEERI) in Doha, Qatar in December 2019. This volume is comprised of three main chapters, each describing important case studies and progress on water, energy and environmental questions. A fourth chapter on policies and community outreach on these three areas is also included. This compilation aims to bridge the gap between research and industry to address the socioeconomic impacts of the nexus imbalance as perceived by scientists, industrial partners, and policymakers. The content of this book is of particular importance to graduate students, researchers and decision makers interested in understanding water, energy and environmental challenges in arid areas. Re searchers in environmental and civil engineering, chemistry, hydrology and environmental science can also find unique in-situ observations of the current nexus imbalance in deserts climate to validate their investigations. It is also an invaluable guide for industry professionals working in water, energy, environment and food sectors to understand the rapidly evolving landscape of the EWE nexus in arid areas. The analyses, observations and lessons-learned summarized herein are applicable to other arid areas outside North Africa and the Arabian Peninsula as well, such as central Australia, the southwest of the United States and deserts in central Asia.

This flagship report is a comprehensive review that gives an overall picture of the world's freshwater resources. It analyses pressures from decisions that drive demand for water and affect its availability. It offers tools and response options to help leaders in government, the private sector and civil society address current and future challenges. It suggests ways in which institutions can be reformed and their behaviour modified, and explores possible sources of financing for the urgently needed investment in water. The WWDR4 is a milestone within the WWDR series, reporting directly on regions and highlighting hotspots, and it has been mainstreamed for gender equality. It introduces a thematic approach - 'Managing Water under Uncertainty and Risk' - in the context of a world which is changing faster than ever in often unforeseeable ways, with increasing uncertainties and risks. It highlights that historical experience will no longer be sufficient to approximate the relationship between the quantities of available water and shifting future demands. Like the earlier editions, the WWDR4 also contains country-level case studies describing the progress made in meeting water-related objectives. The WWDR4 also seeks to show that water has a central role in all aspects of economic development and social welfare, and that concerted action via a collective approach of the water-using sectors is needed to ensure water's many benefits are maximized and shared equitably and that water-related development goals are achieved.

Identifies seven priority areas that address the water and energy nexus, namely: (a) Raising awareness and disseminating knowledge; (b) Increasing policy coherence; (c) Examining the water-energy security nexus; (d) increasing efficiency; (e) Informing technology choices; (f) Promoting renewable energy; (g) Addressing climate change and natural disasters.

"This Synthesis publication covers lessons on interlinkages, trade-offs and benefits in managing water, energy and land/agriculture, as well as on protecting the environment derived from several transboundary river basins in Southern Europe, the Caucasus and Central Asia, and one aquifer system in North Africa. These lessons are the result of the collective experience of Parties to the Convention on the Protection and Use of Transboundary Watercourses and International Lakes (Water Convention) and other States, joint bodies for transboundary cooperation, and other stakeholders who participated in carrying out these assessments from 2013 to 2018. This publication also consolidates the methodology which was developed under the Water Convention specifically for the purpose of assessing nexus issues and identifying solutions in transboundary basins. Its development involved a broad range of expertise, gradual refinement upon use, and an intergovernmental review process. The publication was developed in response to a decision by the Meeting of the Parties in 2015 to promote the application of the methodology in other basins worldwide through the sharing of experiences. The publication also aims to foster follow-up action to the nexus assessments. A key dimension of the methodology is the facilitation of multistakeholder dialogues, which convene sector Ministries from riparian countries with often diverging interests in developing and benefitting from a river basin ̶ be it for irrigated agriculture, eco-tourism or energy generation. With the nexus approach, trade-offs and impacts but also mutual interests are identified. This step is subsequently followed by determining jointly with the authorities and stakeholders packages of policy and technical measures to address the problems identified. This intersectoral transboundary dialogue is coupled with a structured analysis, considering technical aspects and governance across sectors. With this composition, the participatory assessment of the nexus applying the methodology provides a better basis from which to address the common challenges of coherence between sectoral policies (as well as between environment and climate policies) and integrated planning. Related shortcomings result in negative impacts causing friction between riparian countries, inefficiencies at different levels, and missed opportunities for more sustainable and cooperative development. The international community explicitly calls for a nexus approach in efforts to implement the Sustainable Development Goals (SDGs). The assessment process can assist countries seeking to initiate, broaden or revisit transboundary cooperation. Furthermore, the resulting insights can also help reinforce national efforts to optimize resource use (e.g. through improved efficiency), improve policy coherence and achieve co-management benefits. The main audiences for this publication are authorities involved in natural resources management, regional organizations and cooperation organizations, international organizations, bilateral development partners, and technical experts."--Publisher's description.

The water-energy nexus, on the one hand, refers to the relationship between the water used for the production of energy, as a renewable resource for hydroelectricity production, and the energy/electricity generation process itself. On the other hand, it refers to the energy consumed in the extraction, treatment, distribution and disposal of different types of water. ESCWA is implementing a UN Development Account Project on "Developing the Capacities of ESCWA Member Countries to Address the Water and Energy Nexus for Achieving Sustainable Developing Goals". The DA project targets to strengthen the capacity of ESCWA member countries to achieve an integrated and sustainable management of water and energy resources to contribute to achieve the Sustainable Development Goals (SDGs). The project is implemented through two parallel and complementary tracks. The first track targets high-level officials in ministries responsible for water and energy while The second track focuses on water and energy public service providers.

Master's Thesis from the year 2018 in the subject Engineering - Civil Engineering, grade: 3.6, Addis Ababa University (Center for Development Studies), course: Environment and Sustainable Development, language: English, abstract: Access to modern energy is a key element in rural development. This thesis identified the Impact of Small Scale Biogas Technology on Household Income and Health in Ada’a Woreda, Oromia Region, Ethiopia. 9 kebeles were purposively selected where there are high number of biogas users. The descriptive statistical significances and the association of the dummy and continuous variables with the dependent variable were tested using chi-square and t-test. Propensity score matching was used to assess the impact small scale biogas technology has on health and income of household. The study found out small scale biogas technology is favorable among users due to; subsidy form the government; relatively cheap comparing to other fuel sources; as it considers the health economic and environmental benefits; as it saves fuel; it being smokeless; its durability; the fact that it cooks quickly; as it effectively uses waste from farm and produces compost for farm use. The result from Propensity score matching indicated that small scale biogas technology has a significant and positive impact on health . So, the impact of small scale biogas technology has an average treatment effect of 8249.2, 5968.5, 9961.5, 8652.3 ETB per annum to household income using nearest neighbor, radius, kernel and stratification methods. The impact of small scale biogas technology on health, the study looked at three outcome variables; cost of the treatment for the victims in the households; the number of days spent for fuel collection per week and; total members of the household affected by indoor air pollution (IAP). The impact of biogas on cost of treatment has an average treatment effect of 320.2, 392.5, 339.2, and 332.8 ETB using nearest neighbor, radius, kernel and stratification methods respectively. The impact of biogas on number days spent for fuel collection has an average treatment effect of -1.5, -1.4, -1.3, and -1.3 days using nearest neighbor, radius, kernel and stratification methods respectively. Lastly the impact of using small scale biogas technology on total members of household that are affected by the illness -1.2, -1.2, -1.2, and -1.2, member using nearest neighbor, radius, kernel and stratification methods respectively. As the technology has a great potential in promoting sustainable and renewable energy, much effort should be done in promoting the technology, awareness raising to non-user household and peer education should be done.

"The Arab countries have much to gain from considering the linkages between water, energy and food security in their pursuit of sustainable development, given the stressors, constraints and strong interdependencies that characterize the relationships between these three sectors in the region. The nexus analytical framework can be applied at various scales of analysis and can accommodate consideration of the varying natural resources endowments and different production and consumption patterns that exist among Arab countries. It can facilitate the examination of the complex challenges that stymie water, energy and food security in the Arab region, such as shared water resources management, decision-making related to the energy mix and energy efficiency in Arab countries, and national efforts to achieve food security in face of water scarcity, land degradation and development objectives. This sixth issue of the ESCWA Water Development Report presents an analytical framework and a series of case studies for understanding the water-energy-food security nexus in the Arab region. The analytical framework considers the linkages that affect the achievement of water, energy and food security through the lens of sustainable development and the achievement of the 2030 Sustainable Development Goals, with a view to mitigating climate change and ensuring access to food, water and sustainable energy for all in the context of a human-rights approach."--Publisher's description.
