Assessing the economic impact of redistributing water within a catchment: A case study of the Musi Catchment in the Krishna Basin in India AgEcon
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...

DYNAMICS OF AGRICULTURAL GROUNDWATER EXTRACTION AgEcon
Hellegers, Petra J.G.J.; Zilberman, David; van Ierland, Ekko C..
Agricultural shallow groundwater extraction can result in desiccation of neighbouring nature reserves and degradation of groundwater quality in the Netherlands, whereas both externalities are often not considered when agricultural groundwater extraction patterns are being determined. A model is developed to study socially optimal agricultural shallow groundwater extraction patterns. It shows the importance of stock size to slow down changes in groundwater quality.

WATER AS AN ECONOMIC GOOD IN IRRIGATED AGRICULTURE: THEORY AND PRACTICE AgEcon
Hellegers, Petra J.G.J.; Perry, Christopher J..
This report describes the results of the Water Valuation and Pricing project, which aims to provide insight into the relevance of economics to typical problems found in irrigated agriculture. It first considers the theoretical basis for the use of economic instruments, then considers their usefulness in the context of five case studies of irrigated areas - in Egypt, India, Indonesia, Morocco and Ukraine. The case studies confirm that competition for scarce water and shortage of funds are widespread. The study provides insight into the current price paid for water, the cost of service provision, and the value to irrigators of the water they receive. The analysis shows that volumetric pricing is unlikely to be relevant to demand management because the price...

Water Pricing and Valuation in Indonesia: Case Study of the Brantas River Basin AgEcon
Rodgers, Charles; Hellegers, Petra J.G.J..
The increasing demand for water and limited degree of cost recovery for irrigation water delivery are important challenges for policymakers in Indonesia. To meet the increasing demand for water, it is important to reduce water use in irrigated paddy cultivation, long the dominant consumptive user, and to divert water away from agriculture to domestic and industrial sectors. Reducing water use in irrigated agriculture can be achieved through various means, including rationing, improved user management, and water markets. The appropriate method depends on the situation specific to each basin. In the Brantas Basin in East Java, rationing is already practiced, but often leaves the non-licensed, (non-paying) irrigators with insufficient supplies. Moreover, very...
