A Strategic Analysis For Small Hydro Power (Shp) Development In Himachal Pradesh, India, Steven Spicer
A Strategic Analysis For Small Hydro Power (Shp) Development In Himachal Pradesh, India, Steven Spicer
Undergraduate Review
In addition to India currently being the second most populated country in the world, economists at Goldman Sachs have listed India as one of the five BRICS countries (Brazil, Russia, India, China, and South America) projected to be most dominant economies by 2050. In spite of the rapid growth in India’s economy, there are still many serious issues affecting the majority of its people. The US Energy Information Administration reports that roughly 25% of India’s 1.2 billion people are living without access to electricity; which translates to 300 million citizens without power (EIA, 2013). Various estimates put India’s energy supply …
Environmental Considerations Of Small-Scale Hydroelectric Power Plants In Himachal Pradesh, India, Darwin Werthessen
Environmental Considerations Of Small-Scale Hydroelectric Power Plants In Himachal Pradesh, India, Darwin Werthessen
Undergraduate Review
The need for increased energy production in India is high priority and hydroelectric power has been identified as having the greatest potential for achieving energy independence. The Indian government has continually created more streamlined methods for efficient implementation of hydroelectric facilities with an emphasis on small-scale (<25 MW) and micro (<5 MW) facilities in the more remote regions. Himachal Pradesh has effectively achieved one hundred percent electrification due to these initiatives and realized some of the most successful development in the nation with respect to rural electrification and improved infrastructure such as roads, schools, and hospitals. Hydroelectricity, and especially that produced through run of the river type systems, is generally embraced as a renewable source of energy by many established standards. Small scale run of the river facilities are also heralded for the minimal impact to the environment. However, with increased development and construction in continually industrializing areas, measurable human impacts have increased felt within the environment and ecosystems. Several studies and papers published by the Indian government, as well as the state government of Himachal Pradesh, identify these impacts as low to nonexistent. In contrast, a growing number of studies refute this claim and deserve consideration. There is a diversity of opinion on this subject. Some secondary sources indicate minimal to non-existent environmental impacts stemming from projects less than 25 MW, considered as Small Hydro Power (SHP); while other sources express significant concern. Interviews with government officials and researchers in the Indian states of Himachal Pradesh and Uttarakhand as well as in the capital city of Delhi revealed a wide range of views. This paper presents observations and argues for greater exploration of these issues through future research.
Hydropower Development In Himachal Pradesh: A Stakeholder Equity Analysis, Eliott Rousseau
Hydropower Development In Himachal Pradesh: A Stakeholder Equity Analysis, Eliott Rousseau
Undergraduate Review
Seen as the champion of green energy to some and environmentally disastrous to others, hydropower is a multifaceted issue. As it continues to be developed in India, some of the most remote locations and vulnerable people are being affected. This paper holistically examines the process of hydropower development in rural Himachal Pradesh. The locus of this study is tribal region of Bharmour Tehsil within Chamba District of Himachal Pradesh, India. Aspects pertaining to project commission, the consent process, and government sponsored rural development schemes are examined, with emphasis given to equity among rural stakeholders. The nature of this project was …
Delineation And Characterization Of The Furnace Brook Watershed In Marshfield, Massachusetts: Potential Impact Of Water Supply Extraction, Erik Croll
Undergraduate Review
The Furnace Brook watershed in Marshfield, Massachusetts supplies a coastal community of 25,132 residents with nearly 45% of its town water supply (Marshfield 2012a). As in many other coastal communities, development pressure in Marshfield has increased in recent years, creating a growing demand for freshwater extraction. It has been observed, however, that portions of the stream and Furnace Pond disappear entirely at certain times of year, generally between June and August, depending on the rate of groundwater extraction. This has created a conflict between protecting the designated wetland areas and meeting public pressure for water resources, even within what is …
The Effect Of Hydrochloric Acid Strength On The Nanometer-Scale Dissolution Topography Of Calcite Crystal Surfaces, Jennifer Fruzzetti
The Effect Of Hydrochloric Acid Strength On The Nanometer-Scale Dissolution Topography Of Calcite Crystal Surfaces, Jennifer Fruzzetti
Undergraduate Review
The physico-chemical mechanisms by which rock-forming minerals dissolve in natural fluids are controlled by a number of environmental factors. In this study, we investigate dissolution mechanisms by observing how the nanometer-scale surface topography of calcite is affected by the acidity of etching solutions. Here we report atomic force microscope (AFM) observations of calcite crystal surfaces both before and after chemical etching for 10 seconds in 0.01%, 0.1%, and 1.0% HCl solutions. AFM observations show that unetched, freshly-cleaved calcite {10ī4} crystal surfaces are characterized by flat layers separated by steps oriented parallel to calcite cleavage planes. Calcite {10ī4} crystal surfaces etched …
A Greener Disney, Cidalia Pina
A Greener Disney, Cidalia Pina
Undergraduate Review
Disney brings nature and environmental issues to the forefront with its non-confrontational approach to programming meant for children. This opportunity raises awareness and is relevant to growing environmental concerns. However this awareness is just a cursory start, there is an imbalance in their message and effort with that of their carbon footprint. The important eco-messages that Disney presents are buried in fantasy and unrealistic plots. As an entertainment giant with the world held magically captive, Disney can do more, both in filmmaking and as a corporation, to facilitate a greener planet.
The Invasive Asian Shore Crab, A Dominant Species On Southeastern Massachusetts Beaches: A Cause For Concern, Kimberly Westgate
The Invasive Asian Shore Crab, A Dominant Species On Southeastern Massachusetts Beaches: A Cause For Concern, Kimberly Westgate
Undergraduate Review
The non-native Asian shore is becoming a dominant species in southeastern Massachusetts beaches. A study was conducted to test whether environmental conditions across beaches in southeastern Massachusetts had an effect on the crab species inhabiting those areas. Although this was the main focus, it was found that the invasive Asian shore crab has had an ecological impact on the native crab populations. Six southeastern Massachusetts beaches (Scituate Beach, Plymouth Beach, Mass Trust Estuary, Ellisville Harbor, Gooseberry Island, and Sandwich Marsh) were visited and crab species were counted in measured sites, generally two sites pe r beach. Crab species found were …
Solar And Topographical Breeding Habitat Preferences Of Two Damselflies Calopteryx Aequabilis And Calopteryx Maculata, Christopher St. Andre
Solar And Topographical Breeding Habitat Preferences Of Two Damselflies Calopteryx Aequabilis And Calopteryx Maculata, Christopher St. Andre
Undergraduate Review
As the global climate changes many species are forced to adapt, but if the climate changes beyond their tolerance levels they can face extinction1. Scientists need to work fast in order to mitigate these extinctions. Using field observations of species’ habitats coupled with the use of geographic information systems (GIS), researchers can model the locations of ideal habitats. Using these models, scientists can work to improve conservation efforts by raising the populations of dwindling species or predicting locations to place new subpopulations. Data used in GIS are spatially explicit, so stored within individual data sets and information systems are locational …
Life History Parameters Of The Humpback Whale (Megaptera Novaengliae) In The Waters Of The Gulf Of Maine For The 2007 Feeding Season, Meghan Wert
Undergraduate Review
The humpback whale (Megaptera novaengliae) is an endangered species of baleen whale that feeds in the waters of the Gulf of Maine during the spring, summer and fall. The worldwide population of humpback whales ranges from 60,000 to 80,000 individuals and the population within the Gulf of Maine is estimated between 9,000 to 11,000. Humpback whales are a large baleen whale that reaches an average length of 40 to 50 feet and a weight of 35 to 40 tons. Although protected worldwide since the International Whaling Commission in 1964, this population has increased slowly and is still considered …

Chronological Patterns Of Emergence Of Dragonflies In Carver Pond, Bridgewater, Ma, Chris Haslam
Chronological Patterns Of Emergence Of Dragonflies In Carver Pond, Bridgewater, Ma, Chris Haslam
Undergraduate Review
In this study larval skins of dragonflies were collected counted and studied in order to find peaks and patterns of emergence and correlate with environmental factors. One of the most important stages of the life of a dragonfly is the time when it changes from a larval aquatic insect into a flying adult. This stage takes place when the dragonfly emerges out of its skin called the exuvia. Exuvia were collected from two sites at Carver Pond, Bridgewater, Massachusetts to determine differences in species emergence patterns from May 26, 2003 to July 18, 2003 and correlated with environmental conditions. Peak …

Research Note: Pcbs In The Acushnet River Estuary, Jacek Sulanowski
Bridgewater Review
Much media attention has recently been devoted to potentially toxic substances disseminated throughout various components of the environment. In almost every case these substances had been manufactured and distributed under the assumption that they did not pose a threat to man. Indeed when tested by methods current at the time of their initial introduction the substances were considered benign. It was only later when technologically advanced and more sensitive methods of analyses were developed that the presence of these substances was considered to be of real concern. Unfortunately, in the interval between introduction and detection, the accumulation of these substances …
