Developing A Sustainable Water Supply In The American West: The Case Of Rio Rancho, New Mexico, Hubert B. Stroud, Mary K. Kilmer

Suburban Sustainability

Suburban and urban communities in the American West are challenged by rapid population growth combined with limited natural resources. Supporting sustainable development is of great concern in this region and in similar regions throughout the world. This research examines the sustainability of the water supply within a rapidly growing suburban city in the American West. The city, Rio Rancho, New Mexico, began as an interstate land sales operation and rapidly became a “boom” town, in part because of its location near metropolitan Albuquerque.

Because of a very limited water supply and an increasing demand for water associated with population growth, …

U.S. Oil Reserves And Peak Oil, Trang Luong

Undergraduate Journal of Mathematical Modeling: One + Two

We use calculus methods to estimate the quantity of U.S. oil reserves. We consider a model that consists of an exponential function with four unknown constants. We fit real oil production data to determine the unknown constants. With the constants determined we use the function to find the year in which the U.S. oil production reached its peak. We also estimate the amount of petroleum produced until the end of 2006, and the undiscovered oil reserves to be produced in the future.

Management In A Neotropical Show Cave: Planning For Invertebrates Conservation, Thais Giovannini Pellegrini, Rodrigo Lopes Ferreira

International Journal of Speleology

Lapa Nova is a dolomitic cave about 4.5 km long located in northwestern Minas Gerais state, Brazil. The cave experiences intense tourism, concentrated over a single period of the year, during the Feast of Our Lady of Lapa. In order to evaluate the impacts felt by the invertebrate community from this tourism, a new methodology was proposed. Four types of areas (intense visitation area, outlying visitation areas, moderate visitation areas and no-visitation areas) were sampled for invertebrates. There was one sampling prior and another on the last day of the 128^th feast, to evaluate the effects of visitation on …

The Subterranean Fauna Of A Biodiversity Hotspot Region - Portugal: An Overview And Its Conservation, Ana Sofia P.S. Reboleira, Paulo A.V. Borges, Fernando Gonçalves, Artur R.M. Serrano, Pedro Oromí

International Journal of Speleology

An overview of the obligate hypogean fauna in Portugal (including Azores and Madeira archipelagos) is provided, with a list of obligated cave-dwelling species and subspecies, and a general perspective about its conservation. All the available literature on subterranean Biology of Portugal since the first written record in 1870 until today has been revised. A total of 43 troglobiont and 67 stygobiont species and subspecies from 12 orders have been described so far in these areas, included in the so-called Mediterranean hotspot of biodiversity. The subterranean fauna in Portugal has been considered moderately poor with some endemic relicts and it remains …

Forest Conservation In A Changing World: Natural Or Cultural? Example From The Western Carpathians Forests, Romania, Angelica N. Feurdean

Studia UBB Geologia

In order to plan for the future management of some of the most biodiverse forests of Europe, it is essential that we understand under which condition they arose and the time and processes responsible for their variability. Here, I highlight the main findings from the palaeoecological (pollen and charcoal), archaeological and historical investigation comprising the last 6000 years, in the Apuseni Natural Park, NW Romania and discuss the effect of the past land use and forest management on these forests. I then ask what does it mean in term of conservation values if these forests are not natural but a …

Baia Mare Geological And Mining Park – A Potential New Geopark In The Northwestern Part Of Romania, Marinel Kovacs, Alexandrina Fülöp

Studia UBB Geologia

The Baia Mare region is a very well known mining area, with an excellently studied regional geology in Romania. The geological heritage has been strongly incorporated in the economic and social development of the region which is now subject to the cease of the mining-based activities. The natural heritage, as well as the historical and cultural values of the region, will contribute substantially to the future development. The region of Baia Mare has a high potential for founding a new Geopark in the Gutâi Mts. volcanic area. The main geological, mining/archaeological/historical, ecological and cultural issues of the Baia Mare region …
