The present study attempts to estimate individuals’ willingness to pay for recycled water irrigation, in order to enhance the water supply and ensure the continuation of irrigated agriculture in Nestos catchment. Contingent valuation method has been developed for the investigation of farmers’ preferences, in monetary terms, to adopt this alternative water source for irrigation purposes. The applied method is regularly followed in the framework of environmental valuation. The results of the survey are based on data collected from questionnaires, which were answered by respondents at a river basin scale. In a representative sample of 302 farmers, we find that 64.2% of them expressed a positive stance towards using recycled water, a fact that results in lower environmental impacts. However, findings indicate that participants are willing to pay a significantly less amount of money than they already pay, for freshwater. Additionally, the analysis demonstrates that the use of recycled water in agriculture is more acceptable to respondents who are aware of its environmental benefits. Therefore, the provision of complete information on the welfare of using recycled water for irrigation to farmers may lead to greater adoption intention and a greater environmental benefit.

Abstract One of community empowerment programs implemented by the Ministry of Environment and Forestry is the construction of a Micro Hydro Power Plant (MHP) for communities around forest areas. One of the environmental services provided by forests is hydrological benefit in the form of water source to drive MHP turbines. The existence of the perceived benefit will trigger public awareness to participate in preserving forest functions. Rewards for benefits generated from forests can be manifested through efforts to conserve water resources jointly between the community and the party that manages the area. In this regard, this research is conducted to determine the willingness to pay of MHP users around the North Buton wildlife reserve to maintain the MHP unit and support forest resource conservation activities. This study employes the contingent valuation method (CVM) to calculate the willingness to pay value. The results show that MHP users are willing to pay IDR 2,611.- for each kWh of electric power. The willingness to pay is influenced by the amount of electricity consumption and the amount of income of the respondent. If it is calculated based on the volume of water used, the total willingness to pay for environmental water service is IDR 414.-per 1 liter per second.

Bidding Process

The contingent valuation method was used to estimate willingness to pay (WTP) for the operation and maintenance of an improved water source in the villages of Kigisu and Rubona in rural Uganda. The survey was conducted in August 2011 and administered to 122 households out of 400 in the community, gathering demographic information, health and water behaviors, and using an iterative bidding process to estimate WTP per 20 L for a public tap. The data were analyzed using an ordered probit model, which predicts monetary intervals for households' WTP. The model predicts a mean WTP of 356 Ugandan shillings (USD 0.183) per 20 L from a public tap. It was determined that the number of children in the home and the distance from the existing source are significant in influencing household's WTP, while income, age, and gender are not.

Increasing Demand

Given the increasing demand pressure on water resources coupled with supply holdups and institutional failures, fresh-water resources are increasingly susceptible to depletion and could potentially add to water stress in India. A vast demand-supply gap necessitates water conservation, including recycling measures. India has a great potential in wastewater treatment, and one of the ways to address it is decentralisation of wastewater treatment given its environmental benefits. Based on the Contingent Valuation Method (CVM), this study assesses Delhi urban households’ willingness to pay for the Operation & Maintenance (O&M) costs of a local Wastewater Treatment Plants (WWTP) that supplies residential complexes treated water for toilet-flushing. The study found that if freshwater prices rise sufficiently for consumers, they may be willing to subsidise a decentralized WWTP to cover at least their non-potable water uses. In addition, the co-provision of such public goods can become an important supplement to urban municipal finance.

Ecosystem Protection

Forested watershed provides abundant ecosystem services for water users including catchment area protection, flood regulation, provisioning of clean drinking water and climate regulation. However, the value of ecosystem services only partially takes into account by policy makers and indirectly cause overexploitation of natural resources. This study observes the economic role of women in protecting watershed ecosystem by calculating willingness to pay (WTP). Langat Basin is an imperative watershed that supplying fresh water source and other necessities to approximately 1.2 million people within the catchment area. Langat Basin has getting the effect of hasty growth through industrialization and land development actions. Women within Langat Basin has been selected through face to face interview for measure willingness to pay (WTP) towards ecosystem protection. Single Bounded Dichotomous Choice technique in Contingent Valuation Method (CVM) is engaged to calculate WTP of women. Willingness to pay of women in upstream is RM184.28, followed by women in middle stream is RM168.60 and lastly WTP of women in downstream is RM190.16. The willingness to pay women shows that women has potential to be part of ecosystem protection and signal to policy makers to include women in decision making process especially for environmental perspective.

This report documents a project undertaken for the California Urban Water Conservation Council to create a method to calculate water utility avoided costs and assign economic value to the environmental benefits of raw water savings as a result of implementing urban water conservation programs. It is assumed that water savings associated with implementation of conservation programs can be quantified and represented as a reduction in the demand for water from a particular set of supply sources. This demand reduction may in turn result in a change to the availability of an environmental benefit provided by that source. Environmental valuation, as it is applied here, is relatively new and there are numerous complications, ambiguities, data gaps and differences of opinion in the application of the methodology. For that reason, this report should be considered a pioneering effort to put together all the required elements in a single coherent framework.

This paper presents the major features of two decision support systems (DSS) for river water quality modeling and policy analysis recently developed at the International Institute of Applied Systems Analysis (IIASA), DESERT and STREAMPLAN. DESERT integrates in a single package data management, model calibration, simulation, optimization and presentation of results. DESERT has the flexibility to allow the specification of both alternative water quality models and flow hydraulics for different branches of the same river basin. Specification of these models can be done interactively through Microsoft® Windows commands and menus and an easy to use interpreted language. Detailed analysis of the effects of parameter uncertainty on water quality results is integrated into DESERT. STREAMPLAN, on the other hand, is an integrated, easy-to-use software system for analyzing alternative water quality management policies on a river basin level. These policies include uniform emission reduction and effluent standard based strategies, ambient water quality and least-cost strategies, total emission reduction under minimized costs, mixed strategies, local and regional policies, and strategies with economic instruments. A distinctive feature of STREAMPLAN is the integration of a detailed model of municipal wastewater generation with a water quality model and policy analysis tools on a river basin scale.

Co2 Sink

Curbing greenhouse gas (GHG) emissions to combat climate change is a major global challenge. Although irrigated agriculture consumes considerable energy that generates GHG emissions, the biomass produced also represents an important CO2 sink, which can counterbalance the emissions. The source of the water supply considerably influences the irrigation energy consumption and, consequently, the resulting carbon footprint. This study evaluates the potential impact on the carbon footprint of partially and fully replacing the conventional supply from Tagus–Segura water transfer (TSWT) with desalinated seawater (DSW) in the irrigation districts of the Segura River basin (south-eastern Spain). The results provide evidence that the crop GHG emissions depend largely on the water source and, consequently, its carbon footprint. In this sense, in the hypothetical scenario of the TSWT being completely replaced with DSW, GHG emissions may increase by up to 50% and the carbon balance could be reduced by 41%. However, even in this unfavourable situation, irrigated agriculture in the study area could still act as a CO2 sink with a negative total and specific carbon balance of −707,276 t CO2/year and −8.10 t CO2/ha-year, respectively. This study provides significant policy implications for understanding the water–energy–food nexus in water-scarce regions.

Bangladesh is the most densely populated country in the world. With a total population of around 165 million, the country has constantly been facing food security challenges and other problems. Therefore, increasing food production is one of the feasible solutions to this challenge, and proper agricultural land use for food production bears critical importance. Adopting sustainable irrigation systems and viable technologies would be vital for ensuring efficient use of agricultural land in Bangladesh to safeguard the country's food security. Solar irrigation pumps (SIPs) can be a reliable option in this regard. However, Bangladesh has experienced a prolonged growth rate of SIP installation in the last decade.  The countryhas set a target to install 10000 SIPs by the year 2027, albeit it is a tiny share of the 1.57 million conventional irrigation pumps operating in the country. This study aims to investigate the economic feasibility of the SIPs operating in the northern region of Bangladesh in terms of estimating financial feasibility and environmental benefits. The study is mainly based on primary data collected from the users of SIPs from two Upazilas of Dinajpur and Rangpur districts. A total of 14 SIPs, categorized into large, medium, and small pumps, are selected randomly from the available SIPs in the study areas. The financial analysis reveals that small SIPs are the most profitable option (20% IRR) for investment. Large SIPs are moderately profitable (10% IRR), and their profitability can be improved (10.50% IRR) by introducing additional uses of solar energy. However, medium SIPs are the worst (5% IRR) option for investment. In the study areas, large and medium SIPs are designed for the 'fees for service model', and small SIPs are designed for the 'fees for ownership model'. It is found that the 'fees for ownership model' is more profitable than the 'fees for service model'. Moreover, the net environmental benefit for all SIPs is found almost equal to the given subsidy for installing them. Also, the net environmental benefit per kilowatt peak (kWp) is highest for the small SIPs. This paper recommends that additional use (e.g., husking, grinding, supply excess electricity to grid, and so on) of solar energy can improve the profitability of investmenton SIPs. Further, the government should continue giving grants for installing SIPs and promote 'fees for ownership model' (small SIPs) for personal use. It would speed up the dissemination rate of SIPs and help increase the country's agricultural production and improve the environmental conditions.
