Groundwater, Darcy S. Bushnell, Diego Urbina

Water Matters!

Since the late nineteenth century, New Mexicans have been developing the state’s groundwater resources. From hand-dug wells to proposed wells that could penetrate to 12,000 feet, residents have sought sources to supplement and replace surface water. The state relies upon groundwater to supply almost 50 percent of its needs.

As the population grows and drought intensifies, groundwater sources are tapped with increasing urgency. Limited steps are being taken to preserve groundwater through conservation, groundwater recharge, and regulation.

Community Water Systems, Joanne Hilton, Susan Kelly, Sarah Armstrong

Water Matters!

Apart from the major cities along the Rio Grande corridor, much of New Mexico remains relatively rural. Recent studies estimate a 2013population of around 2,085,500 statewide. In the state fiscal year 2011,about 1,836,000 people, or 88 percent of New Mexico’s population obtain their water from community water systems. Approximately 284,000 people, or about14 percent of the population, receive their drinking water from community water systems serving fewer than 5,000 people. As of 2012, there are 1,148 public water systems that provide drinking water in New Mexico. Of these systems, 593are community water systems; of these, 546 serve fewer than 5,000 …

The Rio Grande As An International River, Margaret J. Vick

Water Matters!

The Rio Grande is divided into two major river reaches and has different legal regimes for each. New Mexico is primarily concerned with the Rio Grande from the headwaters in Colorado to Ft. Quitman in Texas, a distance of approximately 670 miles. This section of the river is the subject of the1906 Rio Grande Convention (Treaty) between the United States and Mexico. The lower section of the Rio Grande from Ft. Quitman to the Gulf of Mexico is the subject of the 1944 Rivers Treaty between the United States and Mexico; the 1944 Rivers Treaty also includes the Colorado and …

Conservation Mooring Study, Urban Harbors Institute, University Of Massachusetts Boston

Urban Harbors Institute Publications

Most boaters who moor their vessels in Massachusetts waters have traditionally employed free swinging moorings that use heavy bottom chain. In important sensitive habitats such as eelgrass beds, these types of moorings often have negative impacts on the benthic habitat – from the circular movement of the chain around the anchor point, and/or from the anchor itself.

This document objectively describes the different characteristics of conventional moorings versus conservation moorings designed to minimize disruption to the benthic habitat. This report includes discussions on the following topics:

• Technologies available
• Ecological impacts
• Functional differences
• Economical differences
• Regulatory issues

These comparisons, along with …

Evaluation And Monitoring Of Ash (Fraxinus Spp.) Tolerant To Long-Term Emerald Ash Borer (Agrilus Planipennis [Coleoptera: Buprestidae]) Exposure, Kathryn G. Hietala

Dissertations, Master's Theses and Master's Reports - Open

Invasive insects that successfully establish in introduced areas can significantly alter natural communities. These pests require specific establishment criteria (e.g. host suitability) that, when known, can help quantify potential damage to infested areas. Emerald ash borer (Agrilus planipennis [Coleoptera: Buprestidae]) is an invasive phloem-feeding pest which is responsible for the death of millions of ash trees (Fraxinus spp. L.). Over 200 surviving ash trees were previously identified in the Huron-Clinton Metroparks located in southeast Michigan. Trees were assessed over a four year period and a hierarchical cluster analysis was performed on dieback, vigor, and presence of signs and …

Can Education Improve The Environment? Applying The Pressure-State-Response Environmental Indicator Framework To Environmental Education Program Outcomes, Brian Johnson

Antioch University Dissertations & Theses

The purpose of this study was to investigate the ways in which environmental education (EE) programs are contributing to environmental quality (EQ) improvement. The research applied the Pressure-State-Response (PSR) environmental indicator framework to the reported outcomes of 103 EE programs in order to 1) determine the extent to which existing EE programs are reporting EQ improvement outcomes; and 2) examine the extent to which these programs are impacting indicators in the three areas of the PSR framework. The study consisted of three research phases: evaluation synthesis, semi-structured interviews, and multiple-case study. The study found that 42 of 103 programs (41%) …

Cost Effectiveness Of Recycling: A Systems Model, David J. Tonjes, Sreekanth Mallikarjun

Technology & Society Faculty Publications

Financial analytical models of waste management systems have often found that recycling costs exceed direct benefits, and in order to economically justify recycling activities, externalities such as household expenses or environmental impacts must be invoked. Certain more empirically based studies have also found that recycling is more expensive than disposal. Other work, both through models and surveys, have found differently. Here we present an empirical systems model, largely drawn from a suburban Long Island municipality. The model accounts for changes in distribution of effort as recycling tonnages displace disposal tonnages, and the seven different cases examined all show that curbside …

Degradable Plastics And Solid Waste Management Systems, David J. Tonjes, Krista L. Thyberg

Technology & Society Faculty Publications

Plastics, which are woven into the fabric of modern life, have consequential impacts on the environment. Many of these are associated with end-of-lifetime processes, and include chemical contamination of the environment and effects from litter. Plastics also complicate waste management processes, causing contamination in composting operations, and having poor recovery rates through recycling. Plastics that are not as biologically recalcitrant, that decompose when use is done, have been perceived as solutions to at least some of these problems. The first generation of degradable plastics did not meet marketing claims; some of the more recent formulations, partly as a consequence of …

Municipal Waste Management: Suffolk County Municipal Systems, Services And Infrastructure, Krista L. Greene, Susan Lienau, David J. Tonjes

Technology & Society Faculty Publications

This report describes the municipal waste management systems used by local governments to manage solid waste in Suffolk County, Long Island, New York. There are ten Towns that serve as the primary planners for waste systems in Suffolk County. Many of the 33 villages in Suffolk County have established their own waste management programs and policies. All programs tend to follow the same general plan of the approaches used by their respective Towns, however. All programs provide some degree of recycling services, although the scope of the services varies tremendously.

Gulf-Wide Decreases In The Size Of Large Coastal Sharks Documented By Generations Of Fishermen, Sean P. Powers, F. Joel Frodrie, Steven B. Scyphers, J. Marcus Drymon, Robert L. Shipp, Gregory W. Stunz

University Faculty and Staff Publications

Large sharks are top predators in most coastal and marine ecosystems throughout the world, and evidence of their reduced prominence in marine ecosystems has been a serious concern for fisheries and ecosystem management. Unfortunately, quantitative data to document the extent, timing, and consequences of changes in shark populations are scarce, thwarting examination of long-term (decadal, century) trends, and reconstructions based on incomplete data sets have been the subject of debate. Absence of quantitative descriptors of past ecological conditions is a generic problem facing many fields of science but is particularly troublesome for fisheries scientists who must develop specific targets for …

Carbon Storage And Sequestration By Trees In Urban And Community Areas Of The United States, David J. Nowak, Eric J. Greenfield, Robert E. Hoehn, Elizabeth Lapoint

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Carbon storage and sequestration by urban trees in the United States was quantified to assess the magnitude and role of urban forests in relation to climate change. Urban tree field data from 28 cities and 6 states were used to determine the average carbon density per unit of tree cover. These data were applied to statewide urban tree cover measurements to determine total urban forest carbon storage and annual sequestration by state and nationally. Urban whole tree carbon storage densities average 7.69 kg C m^‒2 of tree cover and sequestration densities average 0.28 kg C m^‒2 of tree …

Evaluating Population Connectivity For Species Of Conservation Concern In The American Great Plains, Samuel A. Cushman, Erin L. Landguth, Curtis H. Flather

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

Habitat loss and fragmentation are widely recognized as among the most important threats to global biodiversity. New analytical approaches are providing an improved ability to predict the effects of landscape change on population connectivity at vast spatial extents. This paper presents an analysis of population connectivity for three species of conservation concern [swift fox (Vulpes velox); lesser prairie-chicken (Tympanuchus pallidicinctus); massasuaga (Sistrurus catenatus)] across the American Great Plains region. We used factorial least-cost path and resistant kernel analyses to predict effects of landscape conditions on corridor network connectivity. Our predictions of population connectivity provide …

Biosecurity published reports

Barrow Island, the second largest island in Western Australia, is a Class A Nature Reserve and home to a variety of rare and endangered fauna and flora, some of which occur nowhere else. To protect fauna and flora it is essential workers and visitors to the island are aware of the risks that a non-indigenous species (NIS) poses to the ecological balance of Barrow Island.

Workers and visitors to Barrow Island need to be aware and keep their eyes open for any unusual fauna and flora that might be in accommodation units, recreation areas or the work place. Reports from …

Governing The Post-Socialist Transitional Commons: A Case From Rural China, Shitong Qiao

Faculty Scholarship

When the collective declines, who manages the collective-owned land? When the socialist state fails, who possesses the state-owned river? This Article concerns the governance of land and natural resources that are still owned by collectives or the state in rural China. No effective community governance has evolved in rural China to fill the authority vacuum left by the dissolution of the people’s commune system. As a result, such land and natural resources have become real commons. In describing these I use the term “transitional commons” to indicate both the crucial influence of the transitional political legal environment in their emergence …

Acequias, Brigette Buynak, Jerold Widdison, Darcy S. Bushnell

Water Matters!

Acequias are community irrigation systems in the villages and pueblos of New Mexico. They have deep roots in two ancient traditions—Pueblo Indian and Spanish. The Pueblos collected and shared water for centuries before the arrival of Spanish colonists in 1598. The Spanish settlers brought technical knowledge and institutional frameworks for governing irrigation systems, which originated in the Moors’ seven-century occupation of Spain. Both traditions remain important to an understanding of New Mexico’s acequia heritage and the continuing relevance of these “water democracies.”Today, these traditions must meld with state law as the legislature has provided that acequias are “political subdivisions” or …

American Indian Water Rights, Michael Osborn, Darcy S. Bushnell

Water Matters!

Pueblos and tribal reservations are located within most of the larger stream systems in New Mexico. Each has claims to rights to use the water in its stream. In New Mexico, Indian rights are significant because of their early priority dates, because of the large amounts of water rights claimed, or both. In some instances, such claims have the potential to displace a significant number of junior water rights.

Common law theories or doctrines pertaining to Indians continue to be judicially refined and to evolve so that discussing the nature and extent of “Indian water rights” is a complex topic.

State And Regional Water Planning, Brigette Buynak, Susan Kelly, Sarah Armstrong

Water Matters!

A statewide water planning effort was initiated by the New Mexico legislature in the 2003 session. The Interstate Stream Commission (ISC),in collaboration with the Office of the State Engineer (OSE) and the Water Trust Board, was tasked with preparing and implementing a comprehensive state water plan. Regional water planning had begun much earlier, prompted by a lawsuit that El Paso filed against New Mexico in 1983, El Paso v. Reynolds.

The State Water Plan Act of 2003 (Act) was intended to promote stewardship of the state’s water resources and to establish clear policies and strategies for management of the state’s …

Deep Water Regulation, Paul Bossert, Kari Olson

Water Matters!

With most of the surface water in New Mexico fully appropriated and with groundwater sources being drawn down and becoming less reliable, the search for new sources of water is reaching further and further afield of traditional sources and methods. Water wells deeper than 2,000 feet have been rare due to the expense of deep drilling and the uncertainty of finding potable water. Yet the combined circumstances of advances in hydrology and the escalating demand for new water have driven the search for water deeper than was previously considered practical.
