To achieve a good ecological status as proposed by the European Water Framework Directive (WFD; 2000/60/EEC) large investments from urban wastewater authorities are required. The Directive anticipates that cost-effective plans and their economic benefits will offset the high costs required for wastewater upgrading projects. However, urban waste water authorities claim that cost-effective measures are already in place and that little improvement can be made. Current valuation studies have focused either on ecological elements or economic aspects without offering persuading evidence on the cost versus benefits of upgrading projects. To this aim, the current study developed an ecological-economic valuation framework for the comparative assessment of the ecologically sustainable levels in receiving waters and the associated economic effects. The central Wastewater Treatment Plant in Athens (Greece) and the small treatment plant in Vils (Austria) are used as representative case studies.

The current study uses contingent valuation technique to estimate the value of clean water in river Musi in Hyderabad, India. The main source of pollution of the river is untreated domestic and industrial wastewater from the urban area of Hyderabad. Therefore, people’s Willingness To Pay [WTP] for the treatment of their wastewater to different quality levels (Level C, B & A) is estimated using a payment card method. Four variables were considered to influence the willingness to pay - number of years the household lived in Hyderabad; individual perceived importance of controlling water pollution; household income levels and proximity to the river. The results of the logistic regression confirmed that the variables - perceived importance of the respondent of controlling water pollution and household incomes have a significant influence on people’s WTP. Only 30% of the respondents were willing to pay for wastewater to be treated to level C. It was concluded from the survey results that 100% cost recovery of sewerage services and wastewater treatment would not be possible in Hyderabad in the current situation. However, a phased increase in the water tariffs accompanied with simultaneous improvements in service delivery mechanisms and awareness among consumers may be successful in the long-run.

In developing countries the use of wastewater for irrigation can cause considerable harm to public health and the environment. This paper uses contingent valuation to estimate the economic value of safe use of wastewater for crop production on farms within and around Addis Ababa, Ethiopia. We estimate a surprisingly large welfare gain from policies for safe use of wastewater for irrigation. Our study highlights the potential and the possible pitfalls of using nonmarket valuation techniques as an input into public decision making where traditional resource use interacts with public health and environmental concerns in complex ways.

Agricultural water use in agrarian economies is often state subsidized for the enhancement of agricultural productivity while poverty alleviation is also targeted. The Indian agricultural dependent states offer representative examples of undervalued irrigation services mainly sourced by canal networks. However, the current inefficient operation of canal irrigation systems diverts water demand to private initiatives by significantly increasing economic value of agricultural water. The additional recent acknowledgement of economic value encompassed in supportive ecological services enhances the request for reevaluation of agricultural water. The paper attempts to assess the value of irrigation and related ecological services in representative backward clusters of Bihar state in Eastern India. The effects on different landholding groups are analyzed by giving particular emphasis to marginal landholders.

The Indo-Gangetic Basin encompasses most of the fertile landholdings in South Asia. However, low agricultural productivity is observed in the four riparian countries - India, Pakistan, Nepal and Bangladesh - by nailing down rural welfare. Accusations are directed at the inability of water supply sector to ensure high productivity rates and security of subsistence farmers. However, little is known about the demand side and farmers’ perceptions towards the effects of water use on agricultural productivity. To this aim, we conduct an economic assessment through a stated preference approach on crucial institutional and environmental related parameters of agricultural water that could enhance productivity potential. Also, vital socio-demographic elements are examined as influential factors. The analysis is based on an extensive research survey accomplished in selected clusters along the Indo-Gangetic Basin.

In this article the authors assess the empirical challenges of estimating the costs and benefits of using wastewater in agriculture. The wide variation in the characteristics of wastewater irrigation complicates efforts to estimate costs and benefits, and to transfer such estimates across locations. They examine wastewater use in four countries in Africa and Asia, where research has been conducted for many years. They find a significant patchwork of results, but no satisfying overall assessment. The authors suggest focusing on the cost-effectiveness of interventions for risk reduction, rather than economic analyses of the full range of costs and benefits of using wastewater in agriculture.

The hydrograph separation method, previously proposed to quantify base flow, seasonal snowmelt, and glacial melt components in river flows within Upper Indus basin underestimates glacial melt component. This is particularly limiting for highly glacierized watersheds. The limitation has been corrected by a further refinement of the method. The results with the refined procedure are highly consistent with the physical characteristics such as hypsometry and glacier extents of the watershed even though the method itself is completely independent of the physical characteristics of the watershed where it is applied. Glacial melt far outweigh snowmelt in the rivers draining the Karakoram and Zanskar ranges. In the Karakoram, on an annualized basis, glacial melt proportion varies from 43% to 50% whereas snowmelt varies from 27% to 31%. On the other hand, snowmelt dominates over glacial melt in the rivers draining the western Greater Himalayas and the Hindu Kush. Here snowmelt percentage in river discharge varies from 31% to 53% whereas that of glacial melt ranges from 16% to 30%. In the main stem of Upper Indus River, snowmelt fraction in most cases is slightly greater than the glacial melt fraction. In the main stem, snowmelt percentage ranges from 35% to 44% whereas glacial melt percentage ranges from 25% to 36%. Upper Indus River just upstream of Tarbela Reservoir carries annual flows constituted of 70% melt water of which 26% is contributed by glacial melts and 44% by snowmelts. We also show that during the later part of twentieth century and continuing into the early part of twenty first century glacial melt contributions to river discharge has decreased compared to the previous decades. This phenomenon can be ascribed to either basin wide loss of glacial mass in the recent decades in the elevation range from where most of the glacial melt originates or glacier growth and stability due to either reduction in energy inputs or increase in precipitation or both at the high altitude bands wherefrom glacial melt water originates.

A valuation scenario was designed using a contingent-valuation approach and presented to decision makers in business firms in Kenya’s Lake Naivasha basin to test how applicable a water fund might be as a potential financing mechanism for a payment for water-related ecosystem services scheme. The findings indicate that measuring a firm’s willingness to invest in ecosystem services could help determine whether a firm would invest and engage with other stakeholders to pool their investments in ecosystem services. Linking the institutional decision-making behaviour of a firm and its willingness to invest in a water fund is the novelty of this article.

The objective of this research is to quantify the economic value of access to irrigation for agricultural lands in rural Nepal, while controlling for the effects of social institutions that can either enhance or detract from agricultural production and land values. The analysis employs the hedonic pricing method (HPM) and uses self-assessed land value data from the Nepal Living Standards Survey, 2011. For the econometric modeling, a Box-Cox transformation supports the selection of the double log HPM model. Results show that the value of land with access to irrigation water is approximately 46 percent higher than the value of non-irrigated lands with a marginal implicit price of approximately NRs. 150,840 in 2011, (representing about seven times the median rural annual per capita income). Results also show the importance of built irrigation infrastructure, such as canals and tube wells, as well as access to multiple sources of irrigation water. We find that land-owner membership in community-managed irrigation systems and forestry user groups has positive impacts on land values. In consideration of extensive 2015 earthquake damages across large areas of Nepal, the findings support the critical importance of repairing irrigation access, especially to built irrigation infrastructures, and supporting community-managed irrigation and forestry user groups, which often lack the initial capital to initiate projects, for restoring rural well-being.

We utilised a practical approach to integrated ecosystem service valuation to inform decision-making at Shivapuri-Nagarjun National Park in Nepal. The Toolkit for Ecosystem Service Site-based Assessment (TESSA) was used to compare ecosystem services between two alternative states of the site (protection or lack of protection with consequent changed land use) to estimate the net consequences of protection. We estimated that lack of protection would have substantially reduced the annual ecosystem service flow, including a 74% reduction in the value of greenhouse gas sequestration, 60% reduction in carbon storage, 94% reduction in nature-based recreation, and 88% reduction in water quality. The net monetary benefit of the park was estimated at $11 million year-1. We conclude that: (1) simplified cost-benefit analysis between alternative states can be usefully employed to determine the ecosystem service consequences of land-use change, but monetary benefits should be subject to additional sensitivity analysis; (2) both biophysical indicators and monetary values can be standardised using rose plots, to illustrate the magnitude of synergies and trade-offs among the services; and (3) continued biodiversity protection measures can preserve carbon stock, although the benefit of doing so remains virtual unless an effective governance option is established to realise the monetary values.
