ABSTRACT Many river systems in Europe have altered morphology and deteriorated ecosystems due to human interference. We demonstrate how conflicting interests of nature, society and economics in the Dutch–German Ems-Dollard system complicate achieving the nature restoration targeted by the EU Water Framework Directive. This article provides a multidisciplinary perspective on the natural characteristics

ABSTRACT Drawing on the results of the Transforming Irrigation in Southern Africa project, we assess positive transitions in smallholder irrigation schemes. The project’s theory of change is evaluated. Soil monitoring tools and agricultural innovation platforms were introduced in five irrigation schemes in Mozambique, Tanzania and Zimbabwe. The synergies between these interventions increased both crop

ABSTRACT This article explores the factors causing the current poor performance of most government irrigation schemes in sub-Saharan Africa. The literature review finds that the poor performance is not primarily caused by socioeconomic and biophysical conditions inherent to sub-Saharan Africa. African farmers have adapted to diverse biophysical conditions and expanded or contracted their area under

ABSTRACT The mechanisms linking growth and inequality are critical for poverty reduction, yet they remain poorly understood at the micro level, as current knowledge is dominated by country-wide studies. This article evaluates farm income growth and changes in inequality among five smallholder irrigation communities in Mozambique, Tanzania and Zimbabwe. Over the period of study, the poorest sections

ABSTRACT Removal of power subsidies in the agriculture sector has been a very contentious issue in India for decades. Free power and tariffs based on the connected load create incentives for farmers to use groundwater excessively and inefficiently. We argue that a pro rata tariff for electricity in the farm sector that reduces the demand for electricity and irrigation water will not only be socio-economically

Australia experiences a wide range and increasing incidence of extreme hydrological events, including step changes in stream flows, extreme drought, bushfires followed by heavy rain, and storm events, which impact water availability and water quality. This article discusses the management of these events in the provision of water services in urban Australia. These events are being actively and effectively

Based on extensive field information, farmer-led small-scale irrigation systems along the dam-regulated Tekeze River is investigated and the likelihood of future irrigation expansion within the area with modelled potential is discussed, considering facilitating and hampering factors. Due to dam-induced hydrologic alterations, downstream socio-ecological systems have strongly transformed as the irrigated

Sustainable water resources management requires long time series of streamflow data. In this study, a Takagi–Sugeno fuzzy rule-based (FRB) model is developed to reconstruct long periods of missing daily streamflow data which is a common problem in developing countries. The FRB model uses observations of neighbouring stream gauges, and thus is advantageous regarding data and time requirement compared

ABSTRACT This paper reviews principles from decision psychology relevant to understanding and increasing acceptance of urban recycled water, and supplements existing literature by suggesting an additional factor: adaptation insensitivity. We integrate into our discussion previously unpublished results from a study conducted in 2007, which surveyed 2680 respondents in five American cities, identifying

To explore the livelihood problems following development-induced displacement and resettlement, this article selects 234 affected families of the Qianping Reservoir in China and builds a livelihood resilience inferred measurement model to assess and verify their livelihood resilience. The research shows that households that have a reasonable income structure or that resettled near their original residence

Under current Spanish law, domestic use of recycled water is only permitted during an officially declared disaster; however, it could be an option from a regulatory perspective. However, would Spaniards be willing to use recycled water in the home if necessary? This study investigates the public acceptance of recycled water use in Spanish households and identifies the determinants of acceptance. In

Bhutan benefits from surplus power generation and associated export revenues, whereas Nepal suffers from power shortages and import deficits. They have contrasting hydropower development, taking different approaches and relying on different sources of development finance in hydropower projects. This study analyzed effective financing approaches for feasible hydropower projects under geopolitical constraints

ABSTRACT The paper provides a description of the efforts taken by the Orange County Water District (the District; OCWD) to insulate itself from public opposition to its potable reuse project, the Groundwater Replenishment System (GWRS). We emphasize how important it is to first understand the challenges faced by concurrent projects in Southern California, and the development and execution of OCWD’s

In this article we investigate the relationship between productivity and profitability, and their drivers: changes in outputs, output and input prices, technical change, technical efficiency change, and scale and mark-up effects. We apply profit decomposition to the water and sewerage companies in England and Wales in 1991–2016. We find that over this period their profit and productivity increased

To foster poverty reduction in drought-prone Araucanía, the Chilean Irrigation Commission is planning an important expansion of irrigated areas. Scenarios incorporating climate change (2030–2059) were simulated for a pilot basin using the WEAP water allocation model, showing that larger irrigated areas, coupled with higher temperatures and less precipitation, are likely to cause severe seasonal water

Differences about fresh water rarely if ever lead to war between neighbouring nations. However, lack of agreement about equitable water use will sooner or later disrupt water management systems. Similarly, unless fresh water is managed sustainably by both nations, their social and economic development will lag, with ultimate effects on any peace agreement. This Viewpoint describes an existing proposal

ABSTRACT Smallholder irrigation is an important pathway towards better livelihoods and food security in sub-Saharan Africa. This article assesses the contribution of farmer-friendly soil and water monitoring tools, and agricultural innovation platforms, towards household income and food security in two small-scale irrigation schemes in Tanzania. Quantitative and qualitative data from farmer’s field

ABSTRACT Many small-scale irrigation schemes are dysfunctional, and learning, innovation and evaluation are required to facilitate sustainable transitions. Using quantitative and qualitative data from five irrigation schemes in sub-Saharan Africa, we analyze how learning and change arose in response to: soil monitoring tools, which triggered a deep learning cycle; and agricultural innovation platforms

ABSTRACT Over four years, a research-for-development project was implemented at the 25 de Setembro irrigation scheme in Mozambique. The project introduced agricultural innovation platforms to overcome barriers to production such as input and output supply chains and poorly maintained irrigation canals. Soil moisture and nutrient monitoring tools were provided so that farmers could improve their irrigation

This study advances methods of measuring access to water by providing a framework that can be operationalized by practitioners to inform decision and policy making. A modified WPI was developed and deployed in India, with results indicating significant differences between WPI and many indicator scores both between and within administrative territories. Spatial analyses identified significant clustering

ABSTRACT Relying on published literature, we reviewed water-energy-food issues in Lao PDR in the context of a policy shift to more sustainable ‘green growth’ and significantly increased infrastructure investment resulting from China’s Belt and Road Initiative. The BRI provides the prospect for the country to address its infrastructure deficit and transform from a ‘land-locked’ to a ‘land-linked’ country

In 2016, extreme drought and saline intrusion led to widespread damage and livelihood disruption for many people in the coastal region of the Vietnamese Mekong Delta. Through an integrated multi-step approach of literature and stakeholder analysis, focus group discussions and interviews with local governments and farmers, an understanding of the local water governance systems and their functioning

ABSTRACT Contingent valuation is used to elicit irrigators’ willingness to pay for soil moisture tools in irrigation schemes in Africa, with various econometric methods employed to mitigate potential bias. Key results include that there is a neighbourhood effect influencing adoption, and that being located downstream and spending more on irrigation water positively and statistically significantly influenced

Multiple-use water services (MUS) can enhance the benefits communities receive from the productive use of water. This article uses household surveys, water samples, focus groups and key informant interviews to examine the potential of MUS in northern Malawi. Specific attention is given to the role of existing rural water supply options and knowledge held by an established smallholder rice farmer group

This article focuses on a major water use in the Ganges Basin, the Ganges Kobadak Irrigation Project in Bangladesh. The objectives of this article are to assess the present and projected irrigation water requirements, the status of the Ganges River and groundwater resources in the project area, and water allocation strategies to fulfil dry-season irrigation requirements in the short, medium and long

ABSTRACT This study aims to identify governance conditions to realize urban bathing water sites using case study material from two cities in the Netherlands. Urban waters in Europe are increasingly considered an attractive feature for bathing, but research on the realization of urban bathing water sites has been limited. We find that it is important to account for the connectivity between water systems

ABSTRACT Employing the heuristic of intersectionality, this study analyzes household effects and responses to water shortage in Gaborone, Botswana, focusing on residents’ adaptive capacity and vulnerability. Using data collected through qualitative interviews, we find that households from all socio-economic backgrounds face various effects from water shortage and use numerous strategies to reduce exposure

ABSTRACT Successful irrigated agriculture is underpinned by answering two critical questions: when and how much to irrigate. This article quantifies the role of the Chameleon and the Wetting Front Detector, monitoring tools facilitating decision-making and learning about soil-water-nutrient dynamics. Farmers retained nutrients in the root zone by reducing irrigation frequency, number of siphons, and

ABSTRACT This article explores the value of Ostrom’s socio-ecological systems framework and Meadows’s leverage point hierarchy, as structured diagnostics, to define systemic problems and avoid approaches based on linear thinking. These frameworks were applied as an ex post analysis of an irrigation scheme in Zimbabwe, drawing on the scheme’s baseline condition and the intervention outcomes. Strong

Predictive hydroclimate information, coupled with reservoir system models, offers the potential to mitigate climate variability risks. Prior methodologies rely on sub-seasonal, dynamic/synthetic forecasts at short timescales, which challenge application in practice. Here, coupling a local-scale seasonal, statistical streamflow forecast with a reservoir model addresses this gap, to explore hydropower

This article presents a qualitative systematic review of English-language academic articles on approaches adopted by the Chinese government to overcome fragmentation and disconnection in water governance. We find that the Chinese government has deployed technical, institutional and discursive instruments, ranging from ‘hard’ to ‘soft’ ways, to improve connectivity between different administrative levels

Least developed countries, with their unique governance and political-economic conditions, face uncommon and under-researched transboundary hydropolitical issues. We analyze the impact of power and political change on the adoption of the Transaqua water transfer megaproject in Central Africa using process tracing and analysis of documents, interviews and fieldwork. We present the key actors and their

ABSTRACT Agricultural production in sub-Saharan Africa has, in recent times, remained lower than the rest of the world. Many attribute this to factors inherent to Africa and its people, such as climate, soil quality, slavery and disease. This article traces the role of agriculture through history and argues that these are not the main reasons. Before the arrival of European traders, complex agricultural

ABSTRACT In spite of groundwater’s growing importance, the 2008 Draft Articles on the Law of Transboundary Aquifers have yet to be fully adopted by the international community. As states contemplate the future of the draft articles, this article aims to reassess them through the lens of the legal principle of reciprocity. To do so, this article provides a framework for the analysis of law via reciprocity

ABSTRACT Water has been a ‘natural’ management priority for Nestlé since its beginnings, more than 150 years ago. Farmers need water to grow food, factories need water to operate, and consumers need water to prepare their dishes. Water touches every part of Nestlé’s value chain. This article describes how Nestlé’s management has made water a priority for the company over time. Nestlé has become a leading

ABSTRACT By 2060, 70% of Singapore’s total water demand will be used for non-domestic purposes. Effective management of this demand will allow the national water agency, PUB, to achieve significant leverage and take strides in water sustainability as land use nears capacity limits in Singapore. Uptake of water conservation projects was sluggish in the initial years due to the high upfront capital and

ABSTRACT This article focuses on the emerging role of citizens and their increasing contributions to local pluvial flood risk management in the Netherlands.

A typology of physical resources and actions, knowledge and advocacy activities shows evidence of locally focused citizen

China has made substantial progress in transforming water governance to respond to water crises and to support rapid socio-economic development. We aim to critically and comprehensively analyze important innovations in managerial approaches, as well as new developments and associated challenges in water policies, by bringing together cutting-edge research and best practices on water resources management

ABSTRACT In 2015, increases in the domestic water tariff in Saudi Arabia were met with significant opposition. Although the increases were needed to address the technical and financial sustainability of the service in the context of extreme scarcity and high costs, insufficient effort was made to explain the changes and prepare the public. This paper examines the trade-offs surrounding the design of

ABSTRACT Hybridization of ‘green’ and engineered infrastructure, informed by protecting or restoring catchment processes, can resolve interconnected demands on catchment ecosystems, potentially also reversing historic degradation of socio-ecological systems. Pressures are acute in water-scarce, developing regions with episodic rainfall, exacerbated by historic presumptions favouring engineered management

ABSTRACT This article synthesizes the literature on Dutch flood risk governance to analyze how external conditions shaped past and present dynamics of cross-sector collaboration for integrated flood risk management in the Netherlands. It traces the extent to which policy and legal frameworks, socio-economic circumstances, political realities, power relations and conflict situations have influenced

The Campoalegre River basin and its sub-basins present water-use conflicts. This study seeks to analyze these conflicts using a disaggregated quantitative approach, so as to better understand existing and potential water stress. We find that the estimated future flows are not sufficient to meet future demand, which will create significant water stress, particularly in certain sub-basins. A tool is

ABSTRACT In this study, a normalized quadratic cost function was employed to estimate total factor productivity for the water sector in England and Wales over the period 1993–2016. Productivity was then decomposed into technical change and scale effect. Technical change is further broken down into pure technical change, non-neutral technical change, and effects due to scale-augmenting technical change

The Mekong River is important for South-East Asia, where it is shared by six countries and serves 70 million people. Its sensitive ecology is essential for the region’s well-being. Managing the river for economic development while protecting this ecology is challenging. This article investigates the institutions in place for governing the Mekong, as how they interact is significant for the region’s

The Three Gorges Project has benefited shipping development in the upper Yangtze River by improving the waterway channel and thus increasing ship load and port handling capacity. However, the Three Gorges lockage freight volume exceeded the designed capacity in 2011 (19 years sooner than expected), becoming a bottleneck for shipping development. For the predicted freight volume, building of a second

ABSTRACT This article investigates water security in Nepal from the perspective of the water-energy-agriculture (food) nexus, focusing on pathways to water security that originate in actions and policies related to other sectors. It identifies promoting development of Nepal’s hydropower potential to provide energy for pumping as way to improve water security in agriculture. Renewable groundwater reserves

China has emerged as one of the world’s most active markets for public–private partnerships (PPP) in the water sector, while the pace of such development globally has slowed in recent years. This article investigates the dynamics of the development of PPP projects in the Chinese water sector through comparative case studies. Our findings suggest that the unwavering pursuit of PPPs as a policy instrument

ABSTRACT Traditional concerns regarding Hong Kong’s water security have centred on water quantity, quality and pricing. In contrast, this article embraces an integrative conceptualization of water security from a governance perspective. A technocratic and supply-oriented water system may overlook challenges stemming from scalar mismatches at the territorial, institutional and discursive levels, as

China is developing a complicated three-aspect water use control system. Spatially, the system includes river basin, province, prefecture, county, permit, and individual users; temporally, it consists of annual average and annual/seasonal frameworks; and in terms of management objectives, it combines abstraction, consumption and use. Technical consistency is required in volume, space, timing, management

While governments in Canada have a duty to act honourably in the development of legislative actions that may affect Aboriginal or treaty rights, Indigenous peoples’ input and knowledge have largely been excluded from the process. The Ontario provincial government recently sought to remedy this failure by engaging with Indigenous groups in the development and implementation of the Great Lakes Protection

ABSTRACT Against a backdrop of economic and population growth, unpredictable climate patterns and rising costs, it is imperative for Singapore to complement supply-side solutions with demand-management strategies on a systemic level to ensure an efficient, adequate and sustainable supply of water for all.

ABSTRACT Following the call of the UK’s Department for Environment, Food and Rural Affairs in its recent Water Efficiency and Behaviour Change Rapid Evidence Assessment 2018, this article seeks to understand the key barriers to effective information-based interventions to encourage household water efficiency in England and Wales and their implications. We review the evidence on information provision

Despite the various water management explorations in China over the past three decades, China’s water problems remain challenging. Recently the Chinese government introduced the river chief system, a collaborative water governance approach, as an update to the previous water management system. We analyze this reform by establishing an analytical framework based on collaborative governance theory. The

ABSTRACT Cape Town recently suffered severe water shortages triggered by a multi-year drought. These shortages were aggravated by reliance on demand management to balance supply and demand in the rapidly growing city. This article considers the interaction between the supply-side planning system and the less systematic approach used to plan and manage what is characterized as the demand-side system
