1	Water-energy-food nexus in India: a review of interlinkages and challenges for a sustainable development Rakitskaya, Katsiaryna January 2021 (has links) The water-energy-food nexus approach, where closely-connected water, energy and food sectors and their interlinkages are considered together, can be useful to fully understand and address impediments to these sectors’ security and their sustainable development. This study is a review of the current status of the water-energy-food nexus in India, main interlinkages and main challenges to the sustainable development of the nexus. One of the main interlinkages is irrigation in the water-food connection, as the majority of water withdrawn in India is used for agriculture. The water-energy interlinkages are crucial not only in the context of hydropower generation, but also due to the large amounts of water being used for cooling of fossil fuel and nuclear power plants. The pressure on water resources is exacerbated by rainfall reductions in India caused by climate change. Social and economic factors, such as population growth, change in food habits, economic growth and technological advances, further increase the demand for water, energy and food. This all poses significant challenges related to water availability and, as a result, water, food and energy security in India.

2	Environmental System-of-Systems Engineering for integrated Nexus design - Developing participatory approaches to design decision making processes in complex human-nature-technology systems Heitmann, Fabian 11 November 2020 (has links) In this thesis, a conceptual framework and related methodological approaches for complex system design are developed and tested. The approaches are based on insights from the fields of Systems Engineering (SE) and System-of-Systems Engineering (SoSE), as well as Natural Resources Management (NRM). The focus of this thesis is on: 1) the development of the System-of-Systems Design Framework “FRESCO”, 2) the development of a methodological framework for participatory systems design, 3) the application of the framework in two case studies, and 4) the development of an evaluation scheme to qualitatively measure the effectiveness of the methodological framework. The overall objectives of this doctoral dissertation are to highlight synergies between SE and NRM and to develop a methodological framework for designing decision making processes in a human-nature-technology context. The complexity of coupled and complex adaptive systems (CAS) such as the Water-Energy-Food Nexus (WEF-Nexus) and sustainability strategies, influences the design of decision-making processes and strategy building. Integrated process design which is promoted by the developed frameworks can assist in such tasks on an urban, regional, and national level.

3	Water Ties: Towards a Relational Understanding of Water Governance Networks in Tanzania and Ethiopia Stein, Christian 10 July 2019 (has links) This interdisciplinary thesis studies the diverse multi-stakeholder networks that are constitutive of contemporary water governance. It examines collaborative governance networks from a relational perspective in two case study watersheds in Tanzania and Ethiopia. Collaborative and networked governance approaches are increasingly promoted to address complex water challenges, but relatively little is known about how the everyday collaborative relationships (i.e. collaboration practices) among the multiple actors involved in the development, management and use of water, shape contemporary water governance processes. In this thesis, I advance, based on intensive fieldwork data collection, a conceptual and methodological framework for studying collaboration networks pertaining to watershed management. I examine local collaborative governance networks in two watersheds, in Ethiopia and Tanzania, from a relational perspective, using complementary qualitative and quantitative social network research methods. The thesis explores the opportunities and limitations of such collaborative governance networks in their concrete functioning, thereby contributing to a more context-sensitive, and nuanced, understanding of the role of governance networks and collaborative governance approaches in the management of water and related resources.
