Assessing the economic impact of redistributing water within a catchment: A case study of the Musi Catchment in the Krishna Basin in India
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Davidson,   Brian; Hellegers,   Petra J.G.J.; Samad,   Madar.
The aim in this paper was to present the details of an economic modeling exercise conducted on the Musi Catchment of the Krishna Basin. The model has the unique characteristic of being able to value the water used on individual crops and in different regions. Thus, the individual values of water used to produce different crops, grown over two different seasons and over five very different regions within a catchment, were determined. This is a significant improvement over previous attempts, where a single value of water in a catchment was derived regardless of what it is used for, when it was used and where it used in the catchment. In addition to the agricultural valuation process, some account was made for the other uses of water and how they should be...

The Problems of Analysing Markets for Irrigation Water
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Davidson,   Brian.
The view that the price of water is too low and that water does not flow to its highest value end use, have led many analysts to conclude that a market for water, in which price can adjust to accommodate changes in the supply and demand for the product, is essential. However, this solution assumes that the market could approach something close to perfect competition, purely by making minor changes within the existing regime of property rights. In this paper it is argued that problems evident in this market stem from a multitude of market failures and characteristics that are particular to it. To understand this case more fully it is necessary to come to terms with the theoretical formulations of the market for water and the practical difficulties...

Economics of Wastewater Treatment and Recycling: An Investigation of Conceptual Issues
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Devi,   Mekala Gayathri; Davidson,   Brian; Boland,   Anne-Maree.
In the context of continuous droughts, the search for alternative water sources and increasing environmental restrictions on discharge of treated wastewater into natural water bodies, treated wastewater recycling offers a potential solution. In this paper the methods needed to assess the questions - to what extent treated wastewater can complement the existing water sources in different sectors and at what cost - are discussed? It was concluded that a comparative Benefit Cost Analysis of different combinations of uses and treatment levels would be a critical component in the development of a decision support tool which could be used by urban planners and water authorities. It was also found that community acceptance of recycled water, distribution of costs...

A framework for efficient wastewater treatment and recycling systems
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Mekala,   Gayathri Devi; Davidson,   Brian; Samad,   Madar; Boland,   Anne-Maree.
Use of un-treated/partially treated wastewater for irrigation in the dry countries of Asia and Africa and recycling of treated wastewater in the water scarce developed countries has become a common practice due to various reasons. While the lack of wastewater treatment to appropriate levels before use is a major problem in developing countries, the high cost of wastewater recycling is the major problem in developed countries. The current paper is part of a doctoral research and presents the conceptual framework for the research and the methodology that can be used to tackle the problems associated with wastewater recycling.

Estimating Distributional Impacts of an Innovation Across Sectors in an Industry: A case study of the Australian wool industry
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Collins,   David J.; Davidson,   Brian.
In this paper an approach that can be used to determine the distribution of a productivity gain on an industry is detailed. In particular, the model developed in this paper extends earlier evaluations by emphasising the crucial role of substitution between inputs across different participants in the supply chain. Crucial to any analysis of an industry are the estimates of the elasticity's of derived demand at each stage and how it changes, as the product is further refined. The wool industry is used to illustrate the effects of an innovation across sectors.

Valuing a Clean River: A case study of Musi River, Hyderabad, India
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Gayathri Devi,   Mekala; Samad,   Madar; Davidson,   Brian; Boland,   Anne-Maree.
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 &amp; 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...
