Value Of Irrigation Water

This paper aimed to construct an improved economic value estimation model (EVIW model) to assess the economic value of water, which plays an important role in the sustainable development of crop planting and irrigation design, especially in arid areas lacking water resources. Firstly, the current EVIW model was based upon improvements and adjustments to the cost-benefit analysis models of previous researchers. Then, to elaborate the whole process of estimation, an empirical study based on the data of Yanqi Basin was conducted. Subsequently, in order to verify the accuracy of the EVIW model, the economic value of irrigation water in this study area was estimated for a second time using the benefit sharing coefficient method. It was concluded that the estimated results of the current EVIW model are in good agreement with those of the traditional benefit sharing coefficient model. The estimation results of the economic value of irrigation water were found to be highly acceptable in terms of accuracy and scientific rigor.

Purpose The subsidization of events by public authorities at different administrative levels has become increasingly important in recent years. Event portfolios are an important supply component of tourism destinations. The development of a valuation tool with an event performance index (EPI) as the key output should enable public authorities to develop transparent, systematic and fair subsidization practices in the future. The paper aims discuss these issues. Design/methodology/approach Using a theoretical impact model and event evaluation practices, this work develops a new holistic valuation tool for events with key indicators along the dimensions of sustainable development. Basic cost-benefit analysis ideas enrich the approach conceptually. Indicator development was based on a process of elaboration that considered the scientific literature, event stakeholders and municipal representatives. Findings The EPI consists of seven core indicators: size, economic value, touristic value and image, innovative strength, value of networking, value of participation and social exchange and relative ecological burden. The application of this tool to a case study revealed that it generates comprehensive and robust indicators of multifaceted and destination-unspecific event values and supports the process of allocating event subsidies using different remuneration schemes. Straightforward and destination-unspecific indicators assure the transferability and adaptability of the valuation tool to different complex and multifaceted contexts of event subsidization. Originality/value The EPI seeks to reduce complexity and incentivize event organizers to meet future sustainable development goals. Additionally, this work contributes to future discussions of both the form and process of event subsidization.

Municipal sludge has economic value as a low-grade fertilizer as it consists of appreciable amounts of the macro and micronutrients. When using sludge as fertilizer, the economic aspect should be taken into account. In this study, the following specific objectives were identified: (a) to investigate the economic feasibility of using sludge as a fertilizer; (b) to estimate the maximum economic distance sludge can be transported as a fertilizer; and (c) to test the economic feasibility of selling sludge using commercial inorganic fertilizer as a bench mark. The study showed that for anaerobically digested, paddy dried, municipal sludge consisting of 3% N, 2% P, and 0.3% K the economic feasibility of transporting the sludge was limited to a diameter of 20 km in the arid zone, 28 km in the semi-arid zone, 51 km in the sub humid zone, 66 km in the humid zone, and 75 km in the super-humid zone. Therefore, the economic feasibility of using sludge as a substitute for or complementary to commercial inorganic fertilizer is dictated by the distance between the wastewater care work and the farm, sludge nutrient concentration, agro-ecological zone (rain and temperature), and the real-time commercial inorganic fertilizer price.

Sustainable development is a priority for the future of our society. Sustainable development is of particular importance to the Architecture, Engineering, and Construction (AEC) industry, both for new buildings and for the renovation of existing buildings. Great potential for sustainable development lies in the renovation of existing office buildings. This paper introduces a new framework for identifying the best set of renovation strategies for existing office buildings. The framework applies selected green building rating system criteria and cost-effective sustainable renovation solutions based on cost-benefit analysis (CBA), and thus provides a novelty in decision-making support for the sustainable renovation of office buildings at an early-stage. The framework covers all necessary steps and activities including data collection, determination of the required level of renovation, selection of the green building rating system, identification of impact categories and criteria, and final evaluation and decision-making using CBA. The framework can be used in conjunction with different systems and according to different regional characteristics. The applicability of the addressing procedure is shown through a case study of a comprehensive renovation of an office building in the city of Maribor.

Green facilities of urban agriculture offer a fertile ground for green innovation, such as rooftop gardens, green curtains, and indoor plant growing, which create a new forms of urban farming economy. The previous studies for cost-benefit analysis of urban agriculture indicated that green facilities could contribute both quantitative and qualitative benefits. The value of green facility strategies of urban agriculture may often be underestimated without transforming qualitative benefits to quantitative benefits. This study examined the effects of green facilities of urban agriculture development in Taiwan. The market reaction was explored by adopting economic value added (EVA) technique for the measurement of both quantitative and qualitative value contributed by green facilities. The results from this study support that there exists interaction between qualitative factors such as indirect economic benefits and social psychological benefits and quantitative factors, agricultural production and energy saving impacted by green facilities. The study concluded that consumers of urban agricultural crops are willing to pay more for eco-friendly products. The establishment of relationship between urban agricultural production and consumption can contribute to sustainability while generating economic opportunities.

ABSTRACTThis paper applies a household production framework (Becker, 1971) to infer the economic value of a cultural heritage site, namely, the Petroglyph National Monument, situated in Albuquerque, New Mexico, USA. The empirical analysis uses benefit-transfer techniques from three source studies: those of Bergstrom and Cordell (1991) and Boxall et al. (2003), which concern willingness-to-pay to hike and view rock art sites; and those of Rolfe and Windle (2003, 2006), which concern willingness-to-pay by Aboriginal and general populations to preserve a cultural heritage site containing rock art. The benefit-transfer analysis estimates recreational values between 3.75 million and 7 million dollars per year (depending on perceptions of the cultural attribute quality) and a nonuse value of approximately 12.5 million dollars per year. By comparison the annualized costs of developing/operating the study site are 8.5 million dollars per year. Thus a partial cost-benefit analysis suggests the study site yields net economic benefits upwards of 7.8 million dollars per year.

This study constructs a simulation model to evaluate the potential for conflict among residential and agricultural users of water in southern Rhode Island. The model estimates the profitability of irrigation of turf farms and projects the total use and the economic value of irrigation water. The results indicate that the economic value of irrigation water compares favorably with current residential water prices in the area. In addition, substantial demand for irrigation water is projected. Given current rates of growth in turf acreage and residential water use, there appears to be a significant potential for conflict, particularly given the absence of well developed institutions for allocating water among users.

The Cost

The Water Framework Directive 2000/60/EC draw attention to Water Quality Monitoring Networks (WQMN) that allows the acquisition of information regarding water streams. Information could be acquired by a spatial and/or temporal approach. However, there is a cost for monitoring water quality. Hence, to determine the spatio-temporal design of the network, the Economic Value of Information must be known to undertake a cost-benefit analysis. In this study, we show how the calculation of the EVOI can help the network manager to answer questions such as: is the cost of monitoring justified? How to allocate a budget between adding a monitoring station or increasing the frequency of measurement of existing stations?

Current environmental policy guidelines are mainly based on cost-benefit analysis and concerned with the restriction of emissions. Sustainable development, on the other hand, is focusing on determining the optimal strategy for the overall performance of both the environment and the socio-economic system. This paper highlights some of the basic problems when developing strategies with the above aim in mind. The implications for decision making are investigated by means of a fictitious model of the economical and environmental interactions in a lake region.

This study investigates the economic value of irrigation water using data collected from 200 smallholder producers in Makhathini and Ndumo areas, KwaZulu-Natal.The study accounts for psychological capital (individual mind-set and attitude affecting motivation to take initiatives) as an important aspect of farm management. This concept focuses more on the ‘soft’ aspects of farm management, which have not been adequately studied in the context of smallholder farming. A sustainable livelihoods framework is employed as a conceptual framework and the role of psychological capital is integrated to explain the variation in water values. The study employs the residual valuation method to estimate water values, principal component analysis to generate an index for psychological capital, and the general linear model to explain variation in water values. The findings suggest that variation in water values was mainly influenced by the location of the farmer, farmer type, physical capital, social capital, land size, farming experience, crop type and psychological capital. The results reinforce the importance of institutional arrangements and collective bargaining as an important element of managing a smallholder farm to increase the economic value of water. To build and develop positive psychological capital for smallholders, it is recommended that government should re-visit the usual model of ‘hand-outs’ (input, finance). It is time to re-consider direct farmer support that entails being heavily involved in their day-to-day activities (i.e., purchasing inputs and running the irrigation schemes on their behalf). Going forward, the focus should rather be on enabling them to change their behaviour to be self-reliant and own their own destiny through on-farm and off-farm economic activities. Moreover, government and other development partners have to understand the long-term behavioural impact (on farmers) of what they do, for instance, entrenching expectations.
