Abstract: This study analyses data on perceptions of the adverse impacts of salinity intrusion on rice farming in the Mekong River Delta. Collected via interviews with the head of 441households and several focus group meetings, the data is used to provide an understanding of current adaptation or coping strategies and, from the insights gained, make recommendations for the management of this increasing challenge. We find that most households are concerned about the impact of salinity intrusion on their livelihood and their capacity to cope in the future. Some strategies are already failing and many farmers will struggle to adapt in the medium-term. Censored generalised Poisson regression and negative binomial regression models are used to identify and test the effectiveness of alternative management strategies. The results suggest that farmers have a preference for the construction of dykes as a means to prevent salinity intrusion. We conclude that farmer willingness to support the construction and improvement of dykes can be improved by providing more information and training.

Abstract: The contribution of agriculture to society is undeniable, as is its impact on the environment. Irrigators' decisions to follow best management practices or implement a policy change, to accept a technology, or even to exit farming, all affect society. Hence the decision‐making behavior of irrigators is of interest to politicians, policymakers, and researchers due to their impact on resource use and social concerns for their welfare. There are numerous studies available regarding the decision‐making behavior of irrigators. Most of them concentrate on decisions within a single time frame, single decisions with multiple driving forces, or multiple decisions with a single driving force. We have conducted a comprehensive review of the existing literature related to irrigators' decision‐making behavior. We used a systematic method to identify relevant publications and used qualitative data analysis (content analysis) to analyze trends and/or patterns across the selected articles. This research provided a typology and an overarching high‐level framework of irrigators' decision‐making process irrespective of the types of decisions made. The results of the study demonstrate that it is highly beneficial to integrate both qualitative and quantitative methods in a single study to get a complete picture of irrigators' decision‐making process. This allows us to ensure that we have captured the relevant drivers of decision‐making in highly dynamic and complex environments. Better knowledge of irrigators' decision‐making process allows regulators to shape improved agricultural policy and increase acceptance by irrigators of technologies that allow water managers to allocate resources fairly among different stakeholders.

Abstract: Environmental water management is a relatively new discipline, with concepts, management practice and institutional mechanisms that are still emerging. The efficient and effective use of environmental water to maximize environmental benefits, or environmental water use efficiency , is one such emerging concept. Currently, much of the focus is on allocative efficiency, where the objective is to achieve a better balance between consumptive and environmental water uses in a cost‐effective way. However, this may not provide the most efficient and effective way to manage environmental water in the long term, where managers are seeking productive (or operational) efficiency . Here, the objective is to maximize environmental outcomes relative to the cost of managing the available resource. This paper explores the concept of water use efficiency in the context of environmental water. This article is categorized under: Engineering Water Planning Water Human Water Value of Water

Abstract: A zombie idea is one that has been repeatedly refuted by analysis and evidence, and should have died, but clings to life for reasons that are difficult to understand without further investigation. The perception that investments in modern irrigation systems automatically save water constitutes a zombie idea. On face value, most would accept that modernizing irrigation systems makes sense: agriculture represents 70% of global water withdrawals while physical irrigation efficiencies range between 25% and 50% worldwide—that is, most of the water entering the irrigation system never makes it to the targeted crop. However, the impacts of modern irrigation systems are complex, and as we show, usually have the opposite effect to that intended through altered cropping and water application decisions by farmers, that aggravate water scarcity. This paper investigates how this zombie idea forms why it persists, even when proven wrong by scientific evidence and how to overcome it.

Abstract: The problem of water overallocation in many regions of the world involves how to include environmental flow provisions for long-term sustainability of river systems, especially under scarce supply conditions. Market mechanisms have provided pathways for returning water to rivers for environmental use. We argue that it is important to consider how both market mechanisms and initial water allocation models contribute to achieving satisfactory environmental flow outcomes. The Murray-Darling Basin (MDB) in Australia has had policy processes applied to it for almost twenty years to address these issues, and provides an excellent basis for case-study analysis. Two MDB case studies are used to consider differences in the interpretation and implementation of environmental flow requirements, and the potential for institutional inertia of the systems within which water markets operate. We identify two simplified models from these case studies—one prioritising environmental rights above consumptive extraction and the other prioritising consumptive and environmental rights equally. However, neither of these case-study models provides the full environmental flow spectrum of base in-stream flows to over-bank flush events. Our findings suggest that combining allocation and market-based rights (a third model) offers an effective means to deliver full-spectrum environmental flows. If governments provide prioritised environmental rights for base in-stream ecosystem benefits, together with targeted temporary and permanent water market acquisitions to meet environmental needs associated with over-bank floods and flushes, there will be lower potential for shortfalls relative to targeted environmental flow outcomes.

Abstract: Coase shows how costly resources are (re)allocated via costly institutions, and that transaction costs must therefore be positive. However, Coase did not elaborate on transitions between institutions which incur positive transaction costs that are characterized by numerous institutional complementarities that is, feedback loops that inform the need for, and pathways toward, institutional change. Economic investigations of complementary modes of (re)allocation are rarely undertaken, let alone studies of transitions between modes. However, modes of (re)allocation that achieve similar results at less cost are generally viewed as having production-raising value. This paper measures the costs of transitioning drought management institutions in Italy toward informal, participatory, and consensus-based approaches during several recent drought events. The chosen model is Drought Steering Committees, which offer a substitute for current formal (less flexible) planning approaches, and where lower transaction costs that are associated with the transition are inferred. Our results highlight the relevance of empirical assessments of ‘costly’ transitions based on a historical study of transaction costs, as well as supporting previous works that highlight the value of contextual analysis in economic studies, in order to identify the benefits of institutional investment.

Abstract: Incomplete information may result in multiple factors combining to jointly affect the consequences of decision-making. The typical response to incomplete information has been tests of robustness and a fixed decisions’ capacity to withstand a wide variety of future conditions. But what of reversed contexts, where the revealed future alters decision-making via experience, learning and innovation such that the decision itself changes? In this paper we contrast a commonly applied expected value robustness metric to state contingent analysis which allows for learning and innovation. State contingent analysis views robustness as how decision-makers achieve profits across all future states by reallocating resources ex post to maximize payoffs and/or minimize losses via outputs that are conditionally specific. Consequently, the state-contingent approach enables researchers to identify the benefits and constraints of resource reallocation—rather than fixed decision-making—over plausible scenarios. Within SCA, scenarios can thus be uncoupled from the historical averages to explore rare events, even if never before experienced, including thin- and fat-tailed probability distribution outcomes and their impact on decision-making, innovation and future solutions. A case study assessment of water resource management in a large river basin provides the basis for our comparison. We find that expected value models mask innovation and adaptation reactions by decision-makers in response to external stimuli (e.g., increased droughts) and under-represent water reallocation outcomes. Conversely, state contingent models represent and report decision-maker reactions that can be more readily interpreted and linked to stimuli including policy interventions, expanding the study of complex human-water systems.

Abstract: People's willingness-to-pay values may be inflated by a variety of influences (e.g. hypothetical bias), which means that stated preference validity tests remain relevant. Recently developed inferred valuation approaches may serve to identify and/or reduce inflated stated preference values. However, economic applications of inferred valuation approaches are relatively limited in the literature, and the evidence remains mixed. This paper examines farmers' willingness-to-pay for salinity intrusion mitigation programs in the Mekong River Delta of Vietnam using both conventional contingent and inferred valuation approaches. Inferred valuation estimates were as much as 31 per cent lower than conventional estimates of willingness-to-pay, and averaged about 24 per cent lower across the groups. We discuss these findings, and the role that commitment costs and provision point mechanism payment vehicles may play. Public policy implications for any future salinity intrusion mitigation program are also outlined.
