<p>Water security can be susceptible to demand increases and climate change impacts. In this case interventions (new infrastructure and/or policies) must be made to meet future demands despite the timing and extent of supply-demand changes are unknown in advance. Given the potential large economic costs of water infrastructure, and the uncertainties in both future supplies and demands, formal planning under uncertainty techniques aiming for robustness and/or adaptability are warranted.</p><p>Staged water infrastructure capacity expansion optimization models help create flexible plans under uncertainty. In these models two types of uncertainties are realized. The first category is the exogenous uncertainty that can be incorporated into the optimization using an a priori scenario ensemble. The second category is the endogenous uncertainty for which the optimized timing and selection of interventions determines when and which uncertainties must be considered. Endogenous uncertainty is therefore ‘decision-dependent’ and cannot be considered as a priori set of scenarios.</p><p>This work describes an extension to an adaptive multistage real options water infrastructure planning optimization problem formulation to incorporate endogenous uncertainty and describe its effect on cost and option selection. We show how endogenous uncertainty propagates when making planning decisions over time on a synthetic case study. The results are contrasted with the deterministic formulation in terms of option activations and the expected present value of the cost.</p>

The Impact

The correlation between the development of a regional economy and the degree of infrastructural development of a country or its territory is a common practice. Considering this, the paper is aimed at studying the impact of water infrastructure on the economic security of regional socio-economic systems in order to develop a water security system for them. A variety of threats against key waterworks can seriously undermine the national economy and water security of regions and cities. Thus, the study analyzes the process of transformation of water infrastructure in the context of ensuring the economic security of regional socio-economic systems. It offers the definition of such categories as “water infrastructure” and “water security of a regional socio-economic system” to formulate a relevant economic policy in Ukraine based on world experience. The study proves the need to attribute water infrastructure to the critical infrastructure sectors of Ukraine and its regions, based on the best world practices in managing water resources and protecting the water infrastructure itself from technogenic, physical, and cyber-physical threats. According to the study results, conceptual bases for ensuring the economic security of regional socio-economic systems are developed, which differ in view of the water security system of the regional socio-economic system, giving priority to the engineering and technical infrastructure of a region.

Residents of the Kathmandu Valley in Nepal face growing water insecurities: too much at times and not enough at others coupled with constant worry about water quality and access. In this rapidly changing city, ancient water infrastructure is a critical mediator of urban water security. Drawing on six years of mixed methods research, I explain the vital role of water heritage for Kathmandu’s water security and urban development by critiquing three common assumptions about water heritage. First, so-called traditional water infrastructure is not a temporary alternative. Second, water heritage is not a living museum. Third, water heritage is not a panacea for modern woes. This article concludes with reflections on the potentials for Kathmandu’s water heritage to address persistent urban insecurities and inequities.

Floods And Droughts

This essay defines the concept of water security and explores the implications of the eternal pursuit of it. I will describe how water security is perceived by wealthy and by poorer nations, the tensions that arise from these differing views, and how these tensions are being resolved in a world in which the geography of economics and power is changing rapidly. I outline a few iconic cases of how societies have built institutions and infrastructure to deal with both floods and droughts. The essay assesses the effects of changes in climate and land use systems, and the differing reactions to the new perception of “nonstationarity”: the idea that these systems are less predictable than they have historically been. The essay concludes with some reflections on the challenges of educating young people seized with passion for the issues of their generation but who may have difficulty taking a long view of water security. Many have been taught about the environmental ravages wrought by water infrastructure, but few understand how these same infrastructure and institutions underpin the water security that the United States has achieved. 1 Similarly, we teach the next generation too little about the remarkable contributions of “thinking practitioners”: experts who are also involved in policy-making and planning–whose work underpins the food, water, and energy security of their societies.

Indus Basin

Water governance and management are important challenges for the River Indus Basin in Pakistan. Water governance refers to social, political and economic factors that influence water management. The water scarcity and water security are a major concern for the state to control its water resources. The study aims to give Sindh water policy by exploring the challenges to Indus Basin in managing water resources and to identify opportunities Indus Basin can look to improve water management. Interviews were conducted from water experts and analysts having 5 years’ experience or more in the water sector of Pakistan through a semi-structured self-developed questionnaire using purposive sampling technique and transcripts were analyzed using thematic content analysis. The findings show that increasing population, climatic change and rising demand of water are major challenges Indus is facing and Indus with time is getting water-scarce therefore need strong institutions, civil society and legislatures to ensure equitable distribution of water and maintain the ecosystem. The study emphasizes that water governance and management are necessary for sustainable use of water. Pakistan, the water stress country needs to address ‘governance’ at a wider scale to solve problems in the Indus Basin for the livelihood of people. The research will benefit the state, water experts, institutions as well as civil society to promote efficient use of water in Indus Basin.
