Invisible landscapes. Historical research and groundwater

Groundwater is an essential part of the planet's water reserves. In modern times, this resource has become increasingly important in determining production methods, modernisation processes and urban settlement patterns, often with contradictory connotations: sometimes a complementary factor, other times a completely alternative resource to the large-scale water infrastructure projects promoted by the state and hydraulic technocracies. Yet, Italian and international historiography has so far paid little attention to groundwater as an object of study in its own right. From a methodological point of view, this requires a close dialogue with other scientific disciplines, involving categories such as the Anthropocene, the hydrosocial cycle and shadow waters, as well as a focus on international historiography, looking in particular at the national or subcontinental contexts that have had to deal with the presence of large underground aquifers.

Embedding Municipal Green Bonds in Mexico City's hydrosocial cycle: 'Green' debt and climate action narratives

Mexico City's municipal "green" bonds (MGBs), issued in 2016 and 2018, financed two water infrastructure projects embedded in the city's hydrosocial cycle (the reciprocal transformation of water and society). The issuance of the MGBs created an entanglement of "green" debt and water circulation, which the city government touted as a successful "green" intervention for climate action. However, this article argues that the MGBs also masked climate injustices and colonial legacies that were already prevalent in Mexico City's water circulation infrastructure, affecting aspects including socio-economic and gender issues. To substantiate this claim, this article adopts climate coloniality and climate justice as analytical lenses and urban political ecology as a methodology to critically examine the "green" label epistemologies and climate action narratives that justify the issuance of MGBs linked to water infrastructure projects.

PV to reduce evaporative losses in the channels of the São Francisco’s River water transposition project

Open water transposition channels in hot and arid regions, like those in the São Francisco River Integration Project (PISF) in Brazil, suffer significant water losses through evaporation. This paper proposes covering these channels with photovoltaic (PV) panels to reduce evaporation while simultaneously generating clean energy. The research aims to quantify water savings and energy generation potential across all channel lengths and assess whether the generated solar power can substitute grid electricity for powering the transposition pumps during peak hours, thereby enhancing energy efficiency. This study analyzed the state-of-the-art of PV generation and calculated their solar potential. Identified the specific characteristics of PISF channels and watercourses considering the regional geography, meteorology, irradiation, and social peculiarities. And, finally, assessed the feasibility of covering the watercourses with solar panels. The results reveal that covering all current PISF channels with PV panels could save up to 25,000 cubic meters of water per day, significantly contributing to water security and improving the quality of life for the local population. Additionally, the project could generate 1200 gigawatt-hours of electricity annually, meeting the energy demands of the transposition pumps during peak hours and promoting energy efficiency within the project. This research paves the way for utilizing PV technology to address water scarcity challenges and enhance the sustainability of water infrastructure projects in arid regions worldwide.

Multivectority of ecological and economic assessment of water resources of Ukraine

The financial and economic mechanism of balanced use of natural resources includes a wide specification of environmental, organizational, economic and financial instruments. The author's vision of the multi-vector nature of the ecological and economic assessment of water resources is outlined, which is a comprehensive approach to the analysis of the use and management of water resources for making informed decisions with the determination of priorities for Ukraine. It is substantiated that formation of fundamental scientific bases for the evaluation of water resources of Ukraine should be based on the use of ecological and economic approaches, in particular: ecological dimension, economic analysis, social dimension, technical analysis, legal and regulatory context, risk analysis, climate change analysis, water infrastructure projects, water conflict management, environmental impact monitoring and assessment, alternative scenarios. A study of publicly available data on the assessment of the use of water resources of Ukraine was conducted. Based on the results of the study, we proposed the structure of a multi-vector model of the tools of the ecological and economic mechanism of water resources assessment, which is systematized according to interrelated instrumental blocks: ecological dimension — assessment of the impact of any water projects or activities on natural ecosystems, aquatic biological resources, and water quality; economic analysis — consideration of economic indicators; social dimension — assessment of the impact of projects on society; technical analysis — analysis of technical solutions, engineering aspects and technological parameters of water projects; legal and regulatory context — consideration of relevant legislative and regulatory requirements; analysis — risk assessment of possible risks and development of strategies for their management. The ecological and economic approach helps ensure balanced use of water resources, taking into account the needs of humanity and the requirements of the environment. On the basis of the multi-vector nature of the ecological and economic assessment of water resources, recommendations on environmental protection, optimal use of resources, social impact of projects, risk management strategies and other important aspects can be provided. The author's approach to theoretical-methodological approaches and methodological provisions regarding the formation of a model of tools for the ecological-economic mechanism of water resources assessment, the effective influence of which is aimed at balancing the ecological, economic and social components of the use of water resources of Ukraine, is proposed. It is substantiated that the functioning of multi-directional tools of the ecological and economic mechanism will ensure both greening and increasing the economic and social effectiveness of the use of water resources, the consolidation of management aspects around strategic tasks and priorities determined by the Basic principles of the state environmental policy of Ukraine for the period up to 2030.

When rain does not run, a fingerprint of uncoordinated water resources development

The management of water resources in a basin can be challenging due to the sharing of water resources among multiple stakeholders and conflicting interests. This often results in imbalanced water resource development across the basin. While small and medium-sized projects are efficiently implemented in the headwater and upstream areas, the commissioning of large reservoirs faces delays due to the substantial investment required and regulatory processes involved. Also, the lack of coordination and synchronization in water resource development between upstream and downstream regions can lead to water scarcity and inefficient utilization of resources in the lower part of the basin. In this study, we assess the occurrence of water scarcity by comparing the frequency of hydrological and meteorological droughts before and after the detected abrupt change in river flow. To facilitate this assessment, we introduced two new indices: the positive to negative phases of hydrological and meteorological droughts. These indices highlight the increasing occurrence of hydrological droughts, which may not necessarily be linked to meteorological droughts during the identified periods. Furthermore, we propose a Monotone drought analysis method to examine the correlation between meteorological and hydrological droughts and address the impact of anthropogenic activities. We applied this analysis in the Sefid-Rud basin, the largest sub-basin in the southern Caspian Sea situated in Iran, which hosts several dams and reservoirs while more dams are in the construction and planning phase. The assessment took place in 24 gauges across the basin from 1978 to 2017 to detect and evaluate the alterations in flow regimes. Our analysis revealed that the unbalanced development of upstream water resources, driven by uncoordinated water infrastructure projects implemented by various decision-makers, has resulted in a decline of available water at critical points within the basin, which will be aggravated with the commissioning of new dams.

Is the media missing the point on the transnational American desalination pipe dream?

AbstractThe media plays a central role in the dissemination of information about globally significant, transboundary issues like world water policy and infrastructure projects. This discussion makes its point of departure on the topic of large‐scale seawater desalination (producing potable ocean water) in the American borderlands and Southwest region, an area that has recently been plagued by droughts, as well as being the subject of much reporting on the feasibility of expanding water infrastructure across the United States and Mexico. In particular, The New York Times has produced a series of stories on water scarcity in the state of Arizona and the “pipe dreams” of building a desalination plant in Mexico that would produce water to be pumped through a national monument, and into major Arizonan metropolitan areas like Phoenix and Tucson. This reportage has been useful in bringing water concerns amidst climate change to a broader audience, simultaneously challenging the well‐known American “growth machine” paradigm. However, when considering the recent scholarship from social scientists and water policy scholars, the media may be missing the point. In this transboundary region, when we consider existing evidence as well as the reports that have emerged in Arizona and Mexico, it becomes clear that water from desalination is a luxury good, and the industry continues to have a dubious political and economic track record when dealing with water providers, public and private. Therefore, more discussions of desalination in world water policy circles need to be asking who is served by desalination, as it increasingly represents a model of the overproduction of water in places that do not need it, therefore entrenching social inequality.

How Should Diverse Stakeholder Interests Shape Evaluations of Complex Water Resources Systems Robustness When Confronting Deeply Uncertain Changes?

AbstractRobustness analysis can support the design and operation of large‐scale water infrastructure projects confronting deeply uncertain futures. However, diverse actors, contextual specificities, sectoral interests, and risk attitudes make it difficult to identify an appropriate robustness metric to rank decision alternatives under deep uncertainty. Here, we clarify how methodological choices affect robustness evaluation using the multi‐actor, multi‐sector Inchampalli‐Nagarjuna Sagar water transfer megaproject in Southern India. We compare a suite of water transfer strategies discovered using evolutionary multi‐objective direct policy search (EMODPS), a strategy proposed by regional authorities and the status quo of no water transfer. We stress‐test these strategies across scenarios that capture climatic and socioeconomic uncertainties and rank them using robustness metrics representing sectoral perspectives and priorities of different actors with varying risk attitudes. Results show a considerable impact of metric choices on robustness rankings of strategies, with compromise solution discovered via EMODPS as robust. The no‐transfer strategy results in the worst water supply robustness with an average volumetric deficit of 17% of total historical demands but emerges as a robust alternative for 6 out of 12 combinations of actor‐sectors with high risk aversion. Also, changes in the amplitude of the Indian Summer Monsoon is identified as the most important uncertain factor determining the failure of strategies. Our findings highlight that the selection of robust solutions should be guided by an understanding of how assumed risk attitudes shape stakeholders' perceptions of vulnerabilities. These findings are generalizable to large infrastructure projects with diverse stakeholders and multisectoral impacts.

The Role of Stakeholders in the Adoption of Public–Private Partnerships (PPPs) in Municipal Water Infrastructure Projects: A Stakeholder Theory Perspective

South Africa receives insufficient rainfall to meet citizens’ water needs and this is compounded by deficiencies in infrastructure for water services because of inadequate investment and a lack of maintenance. Municipal public–private partnerships (PPPs) for water infrastructure are rarely utilised for several reasons. Central to this paper is the evaluation of the role played by various stakeholders in influencing the adoption and subsequent approval of municipal water PPP projects. This study critically examined the role of each stakeholder and how other stakeholders perceive their effectiveness during the approval process of water PPP projects. The conceptualisation and implementation of PPPs involves managing both the public and private stakeholders to achieve the desired outcomes. These diverse stakeholders have different values, anchored by the need for rent extraction (profit maximisation motive) or self-interest, as advanced by stakeholder theory. By means of structured interviews, participants highlighted the limitations of each stakeholder and how these contribute to the negative perception of future PPPs. The obtained data were triangulated with secondary sources. The findings confirmed the pursuit of self-interest by various stakeholders, impacting the pace of PPP adoption of municipal water projects.

Urban water crisis and the promise of infrastructure: a case study of Shimla, India

Urban water configurations evolve through synergetic relationships that are non-linear, spatially variable, and temporally contingent. As urban development grows in complexity, dense water flow networks intensify within the urban landscape and pose a major challenge to urban water governance. At this junction, this study takes up the specific case study of the water crisis in Shimla, a city situated in the Western Himalayas, which was once the summer capital of British India. Shimla witnessed two significant episodes of a severe water crisis in 2016 and 2018, respectively. While the mainstream discourses identified erratic rainfall due to climate change, urban growth, and tourism as the prime causes, the crisis was not marked by absolute scarcity. Multitude configurations of infrastructure politics, distribution, and access produced scarcity, which differentially impacted the people in the city and continues to do so. Marginalized social groups (class, caste, gender, and religion) and people living on the periphery, such as slum dwellers, daily wage laborers, and informal sector workers with inadequate economic and social safety nets seem to have been missing from the discourse. In addition, the crisis events in Shimla have led to institutional changes in the governance of water by establishing a parastatal body for a water utility in the city and the proposal of mega water infrastructure projects for the bulk supply of water from the Sutlej River. Deriving from a situated urban political ecology approach, this study presents an in-depth empirical understanding of the complex urban waterscape of Shimla city, where the tourism industry is a major stakeholder, and a critical analysis of the emerging “new” politics of water, which is also a politics of infrastructure in Shimla's post-crisis phase. It adopts a qualitative research design involving in-depth interviews with different stakeholders in urban water governance in Shimla and a neighborhood-level case study to understand the post-crisis water scenario in the city. Locating the Shimla case study within the broader planetary geography, this study argues that the water crisis, as a context, is dialectical. Despite the implementation of several hydraulic projects and the financialization of nature, the inherent fissures of inequality within the city that cause differential access to water remain.

Multilateral development banks investment behaviour in water and sanitation: Findings and lessons from 60 years of investment projects in Africa and Asia

Abstract Multilateral development banks (MDBs) play a pivotal role in financing water and sanitation infrastructure projects and thus have a major impact on the development of basic services. Although information about the MDBs' investments is publicly available, it is dispersed and not easily comparable. A comprehensive compilation of MDBs' water and sanitation investments has long been lacking. To address this gap, we assess water and sanitation financing by the three MDBs most relevant to Africa and Asia between 1960 and 2020: the World Bank, the African Development Bank, and the Asian Development Bank. We compile a new dataset by drawing on 3,639 water and sanitation projects and assess territorial trends, technology choices, distribution of financial burdens, and reforms to institutional arrangements. We find that MDBs' investments align with changing patterns of urbanization and increasingly finance sanitation infrastructures including non-sewered technologies. However, our results also suggest that institutional reforms have addressed utility efficiency through investment in equipment and skills rather than through increased commercialization and private sector participation. The leverage effect of MDB investment on private financing is negligible, whereas co-financing from local governments dominates.

Exploring Unit Cost Performance for Water Infrastructure Delivery

Various delivery methods are used in the water industry for delivering treatment plant projects, which include the traditional design-bid-build (DBB) method as well as alternative project delivery methods (APDM), such as construction manager at risk (CMAR) and design-build (DB). Research has shown that APDM may improve water infrastructure project delivery performance when compared to DBB. However, utilizing an APDM does not guarantee a project’s successful delivery; other project variables also influence project delivery performance. The objective of this study is to develop exploratory mathematical models to investigate the impact of project-specific delivery factors and attributes on a water project’s success. The authors assess unit cost performance, which is a measure of a water treatment plant’s capacity in million gallons per day, over a project’s total cost. This study consisted of holding an industry expert workshop to review and develop a data collection questionnaire. Information on a total of 15 water treatment plant projects delivered in the US was collected and used to develop multiple linear regression models that explored project-specific key factors and attributes that impact unit cost performance. Results of the regression models revealed four critical variables: (1) use of GMP; (2) project team experience; (3) level of design completed before constructor engagement; and (4) project complexity, to have a statistically significant impact on the unit cost performance of water projects. The findings and contributions of this study can aid water stakeholders in understanding the unit cost performance impact of key project variables on their projects and support them in their project delivery method decisions.

A source tracking framework for attribution of reservoir fluxes in multi-reservoir systems

Reservoir water balance models are required to analyze the impact of alternative designs and operations on the performance of water infrastructure projects spanning multiple basins. However, the impact of such projects on instream ecology and water quality of participating basins remains relatively less explored quantitatively from a design perspective. This is due to the requirement of the complex systems model to simulate processes, which require additional data for parameterization while also increasing simulation time, which affects the performance of optimization algorithms. Here, we propose a conceptual framework to quantify the contribution of water from different basins to various reservoir-related fluxes in a multi-reservoir system. These include water released for demand satisfaction, maintaining minimum environmental flows, and preventing dam failure. For a given reservoir, we quantify the time-varying proportions of water supplied from other reservoirs and from the reservoir’s inflows for each release. We apply this framework to a proposed water transfer project in southern India that caters to the diminishing water supply of the Nagarjuna Sagar (NS) reservoir in the Krishna river basin by transferring water from the Godavari river basin. Our results show that the transferred water majorly caters to the additional demands on the NS reservoir to transfer water further south. We also find that, in general, the transferred water has little to no contribution to satisfying environmental flows downstream of the recipient. However, we do note a very high (up to 50%) contribution of transferred water to environmental flows at the NS reservoir for a few selected realizations of inflows in the monsoon season. Based on prior literature, these releases are concerning given the substantial differences in the ecological composition of fish species in both basins and may lead to invasive species downstream of the NS reservoir. We show how the proposed framework can be used to attribute recipient reservoir releases to donor and recipient inflows and shed light on failure dynamics by identifying fluxes that contribute to failures.

Public–private partnerships as investment models for water infrastructure in South Africa

Developing countries, such as South Africa, have no choice but to look at innovative and/or alternative approaches, such as public–private partnerships (PPPs), as investment models, to ensure that they eliminate their water infrastructure backlogs. The primary objectives of this research were (a) to develop a PPP framework; (b) to identify PPP investment models for water infrastructure; and (c) to determine key categories, criteria and characteristics for cost-effective PPP investment models to ensure the sustainability of the water infrastructure value chain in South Africa. The framework for PPPs identified five broad categories of investment models for the water infrastructure value chain in South Africa. The research results highlight the aspects of PPPs in addressing (a) water infrastructure needs, (b) an implementation strategy for water infrastructure projects, (c) investment policies and (d) the eradication of water infrastructure backlogs. The total investment estimates in the past 20-year period (1998/1999–2019/2020) have been about US$48.36 billion, with the public sector contributing about US$44.32 billion (91.64%) and the private sector only US$4.04 billion (8.36%). Furthermore, the analysis showed that about US$2.75 billion/annum is available based on the current financial arrangements, leaving a financial gap of US$2.83 billion/annum in the water infrastructure value chain.

Would the United States Come to Nazareth’s Aid? Local and International Contests over the City’s Water

This article explores the appeals for aid made by Nazareth’s inhabitants to the US Point Four Program (the predecessor to today’s USAID) to implement a water infrastructure project during the early 1950s. It argues that this was one of several attempts by Palestinians to push back against their exclusion and marginalization by the nascent Israeli state and to retain some measure of autonomy in local governance. Focusing on this settler-colonial setting, and on the role of nonstate actors in what became a protracted and complex conflict, I show how water rights and resource management were embroiled in the political contests that shaped the process of decolonization, at both local and international levels.

How do megaprojects influence institutional change?

Abstract A growing body of research emphasizes the importance of institutions for megaproject performance. Extant studies focus on understanding the characteristics of favourable institutional environments and the governance structures that projects can adopt to navigate both favourable and unfavourable environments. This paper contributes to this research by foregrounding the link between megaprojects and changes in the institutional environments within which they are embedded. Building on a case study of the Thames Tideway Tunnel—the UK’s largest water and sewerage infrastructure project since the privatization of the industry in 1989—the paper presents two distinct ways that projects can interact with formal institutions: institutional compliance and institutional change. A more holistic understanding of the latter is essential because megaprojects can reconfigure production and consumption patterns to the benefit of some and the detriment of others. By contributing to changes in the institutional environment, megaprojects can further entrench these reconfigured patterns into long-enduring formal rules and practices.

The co-constitution of regional politics and massive infrastructures in the Transaqua water project

ABSTRACT Large-scale water infrastructure projects have seen a sudden surge to the top of the political agenda in many countries as a means of addressing developmental goals at both national and regional levels, despite a decline in funding for these projects in the 1990s and 2000s. The Transaqua inter-basin water transfer (IBWT) project, a 2400 km-long canal aiming to connect the Lake Chad and Congo River basins, has been recently hailed by the Lake Chad basin countries, international and regional organizations, and the private sector as the most feasible solution to revitalize Lake Chad’s declining water levels. It has also started to reconfigure the regional politics of two of Africa’s largest basins. This article focuses on this case study and analyses how regional features shape Transaqua and how it simultaneously reconfigures regional politics. Based on concepts such as ‘region’, ‘regionalism’ and ‘regionalisation’ within the international relations discipline and applying mixed methods of discourse, document and media analysis, we show how the project is influencing regional dynamics, alliances and power relations in the Lake Chad and Congo River basins, and how the Transaqua discourse evolves along with regional features such as droughts, water abundance and regional insecurities, despite being in the planning stage.
