EFFECTS OF INCREASED DELTA EXPORTS ON SACRAMENTO VALLEY'S ECONOMY AND WATER MANAGEMENT,

JOURNAL OF THE AMERICAN WATER RESOURCES ASSOCIATION, Issue 6 2003
Stacy K. Tanaka
ABSTRACT: Exports from the Sacramento-San Joaquin Delta are an important source of water for Central Valley and Southern California users. The purpose of this paper is to estimate and analyze the effects increased exports to south of Delta users would have on the Sacramento Valley economy and water management if water were managed and reallocated for purely economic benefits, as if there were an ideal Sacramento Valley water market. Current Delta exports of 6,190 thousand acre-feet per year were increased incrementally to maximum export pumping plant capacities. Initial increases in Delta exports did not increase regional water scarcity, but decreased surplus Delta flows. Further export increases raised agricultural scarcity. Urban users suffer increased scarcity only for exports exceeding 10,393 taf/yr. Expanding exports raises the economic value of expanding key facilities (such as Engle bright Lake and South Folsom Canal) and the opportunity costs of environmental requirements. The study illustrates the physical and economic capacity of the Sacramento Valley to further increase exports of water to drier parts of the state, even within significant environmental flow restrictions. More generally, the results illustrate the physical capacity for greater economic benefits and flexibility in water management within environmental constraints, given institutional capability to reoperate or reallocate water resources, as implied by water markets.

Satellite rural communications: telephony and narrowband networks

INTERNATIONAL JOURNAL OF SATELLITE COMMUNICATIONS AND NETWORKING, Issue 5 2005
Roberto Conte
Abstract Rural communications are important for large and developing countries, and telecommunications systems have been implemented depending upon the available technology at the time. Rural users do not generate the same amount of revenue as urban users do, thus lowering incentives for rural telecommunications investment with service to those regions delayed as long as possible. Voice and data communications are essential to the economic development of a region, and it has been shown that traffic increases rapidly as soon as the service is available. Satellite-based digital networks provide efficient long-distance service to rural communities at lower cost than similar land-based wired networks with acceptable quality. Small earth stations along with Wireless Local Loops can provide both local and long-distance service efficiently and at low cost, offering digital multimedia services on a global scale. This paper focuses on the description of different narrowband technologies used to service rural communities, namely basic telephone and low-bit-rate data (<64 kbps) applications through the use of satellite and terrestrial wireless systems. A basic network economic planning description is presented, and important parameters such as satellite network size, topology and multiple access are identified in order to improve the process of effective and cost-efficient rural communications network design.

Property rights and western United States water markets,

AUSTRALIAN JOURNAL OF AGRICULTURAL & RESOURCE ECONOMICS, Issue 1 2009
Zachary Donohew
This paper addresses water scarcity issues in the American West and examines the allocation of water through the appropriative rights system and the extent markets are used to reallocate water from low- to high-valued uses. The unique physical properties of water make it difficult to bound and measure, which makes defining property rights difficult. Markets are also impeded by disputes over third-party effects due to the interdependencies of water users and complex institutional arrangements that dilute decision-making authority. Analysis of water trading in the western United States indicates that the rate of permanent transfers is increasing over time and urban users are paying higher prices relative to agricultural users.

Regulation versus pricing in urban water policy: the case of the Australian National Water Initiative

AUSTRALIAN JOURNAL OF AGRICULTURAL & RESOURCE ECONOMICS, Issue 3 2006
Joel Byrnes
The Australian National Water Initiative (NWI) builds on the foundations of earlier water reforms, attempts to correct earlier errors in both policy and its implementation, and seeks to better define some of the policy aims with the benefit of hindsight. However, despite the deliberate effort to improve on earlier reforms, the NWI still embodies a significant economic paradox. Although policymakers have shown their faith in the market insofar as allocating water between competing agricultural interests is concerned, they have not shown the same degree of faith in the ability of urban users to respond to price signals. This paper attempts to shed at least some light on this question by examining the responses of a number of State governments across Australia to the NWI. The paper specifically explores the rationale for non-price regulation in the urban context but challenges the long-term viability of this approach. [source]
