| Electricity subsidies for farmers are an expensive legacy of past development policies. The result is overuse of both energy and water in groundwater-irrigated agriculture—threatening the financial viability of the power sector and the future of the groundwater resource itself, along with the livelihoods of the millions who depend on it. The most popular solution is the metered tariff, promoted by international donors and many of India’s state governments. But metering is the ideal solution only if the cost of metering and billing 14 million scattered, small users in India, Pakistan and Bangladesh is ignored. Easier, more feasible and more beneficial in the short run in many parts of South Asia would be the use of a rational flat tariff, which avoids the... |

| The need for a radical shift to more iterative and adaptive solutions in sewage management is increasingly recognized, but our ability to achieve such a shift is constrained by inertia to change. Here, we describe planning in two metropolitan areas that are upgrading their sewage systems, based on interviews with central actors and official documents. Using new institutionalism and concentrating on changes in normative, regulative, and cognitive patterns, we analyze if obstacles to the uptake of innovations can be understood in light of how these patterns counteract institutional change. Our aim is to understand obstacles to reformers implementing a wider vision of sewage management. Our study suggests that even though both Buenos Aires and Vancouver... |

| In this paper, we examine the on-the-ground realities of upstream-downstream negotiations and transactions over ecosystem services. We explore the engagement, negotiation, implementation, and postimplementation phases of a “reciprocal water access” (RWA) agreement between village communities and municipal water users at Palampur, Himachal Pradesh, India. We aim to highlight how external actors drove the payments for ecosystem services agenda through a series of facilitation and research engagements, which were pivotal to the RWA’s adoption, and how the agreement fared once external agents withdrew. In the postimplementation period, the RWA agreement continues to be upheld by upstream communities amidst evolving, competing... |

| Uncertainty of late has become an increasingly important and controversial topic in water resource management, and natural resources management in general. Diverse managing goals, changing environmental conditions, conflicting interests, and lack of predictability are some of the characteristics that decision makers have to face. This has resulted in the application and development of strategies such as adaptive management, which proposes flexibility and capability to adapt to unknown conditions as a way of dealing with uncertainties. However, this shift in ideas about managing has not always been accompanied by a general shift in the way uncertainties are understood and handled. To improve this situation, we believe it is necessary to recontextualize... |

| The growing awareness of the complexities and uncertainties in water management has put into question the existing paradigms in this field. Increasingly more flexible, integrated, and adaptive policies are promoted. In this context, the understanding of how to effect policy change is becoming more important. This article analyzes policy making at the micro level, focusing on the behavior of policy entrepreneurs, which we understand here as risk-taking bureaucrats who seek to change policy and are involved throughout the policy-change process. Policy entrepreneurs have received a certain level of attention in the adaptive co-management literature and the policy sciences in past decades. Yet, the understanding of the actions they can take to facilitate... |

| Fresh water resources provide a platform for complex and often emotional issues to develop, particularly in resource scarcity situations. Bulk water infrastructure contains elements of a public good and proved vulnerable to failures in market and government driven allocation strategies. Common to both are uncaptured costs and benefits due to shortcomings in cost quantification techniques. Natural ecosystems stands to lose the most since ecosystem services are often not quantifiable in monetary terms and therefore neglected in allocation decision-making. This paper took on the challenge of expanding current decision-support in order to promote more inclusive long-term water management. A case-study approach with the focus on a choice related problem... |

| Urban areas such as megacities (those with populations greater than 10 million) are hotspots of global water use and thus face intense water management challenges. Urban areas are influenced by local interactions between human and natural systems and interact with distant systems through flows of water, food, energy, people, information, and capital. However, analyses of water sustainability and the management of water flows in urban areas are often fragmented. There is a strong need to apply integrated frameworks to systematically analyze urban water dynamics and factors that influence these dynamics. We apply the framework of telecoupling (socioeconomic and environmental interactions over distances) to analyze urban water issues, using Beijing as a... |

| The present article uses the modified Arkansas off-stream reservoir analysis and the environmental policy-integrated climate models to examine the impacts of on-farm reservoirs and tail water recovery systems in conjunction with other best management practices on profitability, water use, and sediment control for rice-soybean farming operations. Results suggest that, under limited water availability conditions, reservoirs and tail water recovery systems can improve profitability, reduce ground water dependence, and reduce the movement of sediment, nutrients, and pesticides off-farm. Although reservoirs may not be profitable under plentiful water conditions, cost-sharing opportunities may make them a viable means of addressing environmental concerns. |

| The content, structure, and distribution of mental models can be elicited and measured using a variety of methods. In this article we explore a method for eliciting mental models within the context of water use and management in South Africa. This method is consensus analysis, a technique developed in cognitive anthropology. We used it to analyze qualitative data from semistructured interviews, pilesorts, and questionnaires to test quantitatively the degree of sharing and diversity of mental models within and across social groups. The consensus analysis method focused on comparing the mental models of two key stakeholder groups in the Crocodile River catchment in South Africa, i.e., conservationists and irrigators, to better understand the level of... |

| The vegetative growth and yield of strawberry in relation to irrigation levels and soil mulches are still not well known, mainly for different environmental conditions. Two experiments were carried out in Atibaia, SP, Brazil, during 1995, one in a protected environment and the other in an open field, to evaluate the cultivar Campinas IAC-2712, under different irrigation levels and soil mulches (black and clear polyethylene). Three water potential levels in the soil were used in order to define irrigation time, corresponding to -0.010 (N1), -0.035 (N2), and -0.070 (N3) MPa, measured through tensiometers installed at the 10 cm depth. A 2 × 3 factorial arrangement was adopted, as randomized complete block, with 5 replicates. In the protected cultivation, the... |

| ABSTRACT Rationalization of brackish water management in hydroponic crops is one of the ways to expand and manage water supply in shortage areas. Thus, this work was carried out to evaluate the water and physiological relationships of Iceberg lettuce (cv. Tainá) in plants exposed to strategies of replacement of the evapotranspired volume of saline nutrient solutions. Two experiments were conducted in NFT hydroponic system, in which increasing levels of water salinity (0.2, 1.2, 2.2, 3.2, 4.2 and 5.2 dS m-1) were used to prepare the nutrient solutions. In the first experiment, the evapotranspired volume was replaced with the respective brackish water and, in the second one, with public-supply water (0.2 dS m-1). Both experiments were set up in a randomized... |

| ABSTRACT Knowledge of the terms (or processes) of the soil water balance equation or simply the components of the soil water balance over the cycle of an agricultural crop is essential for soil and water management. Thus, the aim of this study was to analyze these components in a Cambissolo Háplico (Haplocambids) growing muskmelon (Cucumis melo L.) under drip irrigation, with covered and uncovered soil, in the municipality of Baraúna, State of Rio Grande do Norte, Brazil (05º 04’ 48” S, 37º 37’ 00” W). Muskmelon, variety AF-646, was cultivated in a flat experimental area (20 × 50 m). The crop was spaced at 2.00 m between rows and 0.35 m between plants, in a total of ten 50-m-long plant rows. At points corresponding to ⅓ and ⅔ of each plant row, four... |

| Recurring water crises, global water initiatives, and demands for water reforms by development banks, have all pushed water up the agenda of most Mekong-region countries. Many changes have already been made. Now decision makers need to know what has worked, what hasn’t, and why. To find out, IWMI has reviewed new water policies, plans and laws, and assessed participation, the new water ‘apex bodies’, and integrated water resources management (IWRM). The findings show that top-down state policies based on ‘blueprints’ are widely applied in a one-size-fits-all approach, without taking local realities into account. Water planning is still largely expert-driven, and focused on procedures and targets. There is little room for decision-making that is based on... |

| The occurrence of diseases and its influence on strawberry yield in a greenhouse as well as its association with water management are still not well known. So, the aim of this work was to evaluate the effect of different water levels and soil mulches on strawberry plant health and yield in a greenhouse. The experiment was carried out at Atibaia, State of São Paulo, Brazil, from April to December 1995. The experimental design was a 2 × 3 factorial, in randomized blocks, with five replications, and consisted of two soil mulches and three water levels. The soil mulches consisted of clear or black plastic. Trickle irrigation was applied whenever the soil water potential reached -10, -35 and -70 kPa at a depth of ten centimeters. Cultivar Campinas IAC 2712 was... |
