Development Of A Sustainable Water Resource Financing Mathematical Model For Donors And End-Users, Sahar Zavareh Aug 2011

Development Of A Sustainable Water Resource Financing Mathematical Model For Donors And End-Users, Sahar Zavareh

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rural villages and underdeveloped communities represent the largest group challenged by poor water supply and sanitation with inequalities in resources to adequately implement potential solutions and even more with their high risk level of financing, funding is particularly challenging for water projects. Innovative financing alone will not eliminate the burdens of rural villages and underdeveloped communities. The purpose of this thesis is to address the lack of sustainable water financing of water projects in rural areas using a novel framework of a mathematical model based on "system dynamics" using optimal feedback control theory to maximize the performance of a water …


Modeling Natural Resources Scarcity And Proverty Effects On Fertility In Honduras, Nepal, And Tanzania, Ayoub Shaban Ayoub Nov 2008

Modeling Natural Resources Scarcity And Proverty Effects On Fertility In Honduras, Nepal, And Tanzania, Ayoub Shaban Ayoub

UNLV Theses, Dissertations, Professional Papers, and Capstones

This dissertation examines whether the vicious circle theory applies in three developing countries characterized by high population growth. According to the vicious circle theory, natural resource scarcity coupled with poverty leads to population growth via positive effects on fertility particularly in rural areas of developing countries. Population growth then leads to a further increase in natural resource scarcity, creating a "feedback loop." This is the first study to use micro-level data to test and control for endogeneity using a two-stage Probit model (IVPROBIT). The existing literature has largely failed to address endogeneity in the relationship between natural resource scarcity and …


The Barriers Present In More Developed Countries And Less Developed Countries Slowing The Implementation Of Substainability, Luke Giovine Apr 1996

The Barriers Present In More Developed Countries And Less Developed Countries Slowing The Implementation Of Substainability, Luke Giovine

UNLV Theses, Dissertations, Professional Papers, and Capstones

In 1996 the natural resource base of the world is being depleted at a rate far below the sustainable level. This is very evident in less developed countries (IDC), where raw limited natural resources are being poorly utilized and/or exported to more developed countries (MDC). The More Developed Countries such as the United States, Japan, and Germany use a high amount of natural resources and energy to maintain their material Standard Of Living (SOL), and this is at rates above what their own country can sustain with its own natural resources within its own borders. Both MDC's and LDC's are …


Updating The Colorado River Compact, Jeffrey A. Freer Apr 1995

Updating The Colorado River Compact, Jeffrey A. Freer

UNLV Theses, Dissertations, Professional Papers, and Capstones

Water is essential to life in the arid environment of the western United States. For centuries, humans have used the Colorado River to fulfill their needs and until the past 100 years, the use of the river was sustainable. Over the last 100 years, the Colorado River has been dammed and diverted to "reclaim" the arid west for man's use. In 1946, a Department of the Interior report stated that "Tomorrow the Colorado will be utilized to the very last drop. Its water will convert thousands of additional acres of sagebrush desert to flourishing farms and beautiful homes for servicemen, …
