Collective Action By Women’S Groups To Combat Drought And Poverty In Northern Kenya, D. Layne Coppock, Solomon Desta, Getachew Gebru, Adan Wako, Ibrahim Aden, Chachu Tadecha, Seyoum Tezera

Environment and Society Faculty Publications

Collective action can be an effective means of local development and risk reduction among rural people, but few examples have been documented in pastoral areas. We conducted extensive interviews for 16 women’s groups residing in northern Kenya. Our objectives were to understand how groups were formed, governed, and sustained and what activities they have pursued. The groups we interviewed were 10 years old, on average. Charter memberships averaged about 24 women, 20 of whom were illiterate. Half of the groups formed after facilitation by a development partner and half formed spontaneously. Groups are governed under detailed constitutional frameworks with elected …

Public Engagement To Prioritize The Pastoral Research Agenda At The Pastoral And Agro-Pastoral Research Center Of Oari In Ethiopia, D. Layne Coppock, Getachew Gebru, Lemma Gizachew, Sintayehu Mesele, Mohammed Hassena, Solomon Desta

Environment and Society Faculty Publications

The Oromia Agricultural Research Institute (OARI) has a mandate to conduct agricultural and livestock research throughout the Regional State of Oromia in Ethiopia. OARI has recently opened a facility near Yabello town on the Borana Plateau called the Pastoral and Agro-Pastoral Research Center. A meeting was held in August 2006 at Yabello that involved representatives from pastoral communities, the private sector, government, and non-governmental organizations. The aim was to engage stakeholders in a process of problem prioritization and set the stage to create new partnerships to better address pressing problems. The final priorities included: addressing a general decline in forage …

Assessment Of Atrazine In A Rural Water Source: Rough River Lake, Kentucky, Scotty Sharp

Masters Theses & Specialist Projects

Atrazine [2-chloro- 4-(ethylamino)-6-(isopropylamino)-l,3,5-triazine], a widely used herbicide in US corn production, impacts quality of drinking water for many rural water supply systems. Four systems at Rough River Lake, Kentucky, have had high levels of atrazine in raw water and in some cases finished water that have exceeded the legal limit of 3 parts per billion (ppb). The Rough River Lake watershed is 1,700-km2, much of which is located in limestone karst. A hypothesis was developed stating that there would be higher concentrations of atrazine in the northeast section of the Rough River Watershed, located in Hardin County, due to the …

Flash Flooding In Eastern Kentucky: An Analysis Of The 3-4 August 2001 Event, Christina Henry

Masters Theses & Specialist Projects

Limited research exists concerning flash flooding in the United States. However, flash floods can occur anywhere and cause more fatalities than any other weather related natural disaster. Eastern Kentucky experienced an average of 41 flash floods per year (1993-2002), yet little research exists for this region. Therefore, this paper presents an analysis of the particularly devastating flash flood event of 3-4 August 2001, which resulted in $15 million worth of property damage and two deaths. Previous studies indicate that flash floods typically occur under relatively 'benign' conditions, the most common characteristics being a quasi-stationary system and high atmospheric moisture. The …

Changes In Land Cover And Soil Conditions For The Yabelo District Of The Borana Plateau, 1973-2003, D. Layne Coppock, Sintayehu Mesele, Heluf Gebrekidan, Lemma Gizachew

Environment and Society Faculty Publications

It has been proposed that the Borana Plateau has markedly changed in terms of land cover and land use in recent decades, but no hard data have been available to critically assess this claim. In addition, systematic analysis of soil properties has been limited. Research was designed to measure changes in land cover/land use over 30 years in the 400-km2 Yabelo District of southern Ethiopia using three satellite images taken at an average interval of 15 years. Samples were also collected to assess variation in the physical and chemical properties of dominant soils. Results indicated that Yabelo District has indeed …

Derelict Blue Crab Trap Impacts On Marine Fisheries In The Lower York River, Virginia, Kirk J. Havens, Donna Marie Bilkovic, David Stanhope, Kory Angstadt, Carl Hershner, Center For Coastal Resources Management, Virginia Institute Of Marine Science

Reports

In Virginia, an examination of existing derelict trap data retrieved from Chesapeake Bay Multispecies Monitoring and Assessment Program (ChesMMAP) trawl surveys shows the potential effect of derelict traps on fish communities in Virginia waters (Bonzek and Latour 2005). Since 2002, ChesMMAP has attempted to sample 90 stations in the mainstem Chesapeake Bay ranging from the southern edge of the Susquehanna Flats to the Bay mouth in all depths to a minimum of 10 feet during each cruise. There are approximately 4-5 cruises per year and a large mesh bottom trawl is used to capture adult fish of a variety of …

Modeling Soil Erosion In The Upper Green River, Ky, Narcisa Pricope

Masters Theses & Specialist Projects

Off-site soil erosion has tremendous impacts on the present state of most river systems throughout the United States, contributing sediments to channels mainly as nonpoint pollution resulting from land-use and agricultural practices and leading to sedimentation downstream and downwind, a decrease in the transport capacity of streams, increase in the risk of flooding, filling reservoirs, and eutrophication. A primary focus in examining the problems associated with soil erosion arid ultimately in proposing control measures should be on identifying the sources of the sediment. Therefore, a model that would be able to assess soil erosion needs to start by identifying the …

A Long-Term Perspective On Drought In The Great Plains And West, Sherilyn C. Fritz

Nebraska Water Center: Faculty Publications

Management of water resources requires an understanding of the full range of natural variability and its consequences. The weather record, which spans the last 100 years or so, provides a snapshot of the contemporary history of drought and its impacts, but this record is relatively short and is inadequate for understanding long-term trends or for evaluating the magnitude of human impacts. A variety of so-called paleoclimatic records - such as tree rings, lake sediments, and sand dunes - record the history of the environment and can be used to extend the record of climatic variation to older intervals of time. …

The Public Interest Test For Water Appropriations, Sandi Zellmer

Nebraska Water Center: Faculty Publications

Nebraska, like most states, imposes a “public interest” review on applications for water appropriations, changes and transfers. However, Nebraska statutes do not provide any specific public interest criteria for use in evaluating applications for new water appropriations or intra-basin transfers. Under Neb. Rev. Stat. § 46-234, an application for a water appropriation may be refused when denial is demanded by the public interest. The director of the Department of Natural Resources (DNR) has the duty of determining whether the public interest demands the denial of a water appropriation, but is given no express statutory criteria to provide assistance in making …

Instream Flow Legislation, Sandi Zellmer

Nebraska Water Center: Faculty Publications

In the west, state law historically considered water left in the stream to be wasted. Western states, which rely heavily on diversions to meet their water needs, have encouraged full appropriation of rivers and streams. In many cases, however, diversions have resulted in the depletion of stream flow reliant ecosystems and adversely affected fish, wildlife, recreation and river navigation.

A comparison of Nebraska law to the water law of other western states demonstrates that Nebraska’s existing instream flow legislation is quite narrow. Nebraska statutes impose a variety of restrictions on instream flow appropriations, many of which are unique and even …

Water As Property, Sandi Zellmer

Nebraska Water Center: Faculty Publications

The issue of whether water is or should be characterized as property under the law raises considerable controversy. In the western United States, water is typically viewed as a form of property, while in the east it is not. Whether water should be treated as property has been the subject of an extensive body of scholarship. Proponents argue that establishing legally protected, secure private property rights encourages maximum utilization of resources. Also, exclusivity and surety of possession can foster wise investment of labor and stewardship. Conversely, the absence of legally protected interests in property ownership can result in a “tragedy …

The Republican, The Platte And Pumpkin Creek: Current Nebraska Water Policy Issues, J. David Aiken

Nebraska Water Center: Faculty Publications

Potential conflicts between surface water users and ground water users are posing perplexing challenges to Nebraska policy makers. Surface water law is the rule of priority, "first in time is first in right," as administered by the Nebraska Department of Natural Resources (DNR). Ground water is primarily the rule of correlative rights, as administered by local natural resources districts (NRDs). Traditionally ground water irrigators have been subject to few restrictions on drilling new wells or how much water could be used (except in the Upper Republican NRD in southwest Nebraska). Now the DNR can ban new wells in overappropriated and …

Myrothecium Verrucaria : A Potential Biological Control Agent For The Invasive 'Old World Climbing Fern' Lygodium Microphyllum, Tainya Cathia Clarke

FIU Electronic Theses and Dissertations

Non native plants are a threat to ecosystems across the globe, some delicate ecosystems like those in South Florida are in greater danger because of the large number of endemics at risk. Old World Climbing Fern (Lygodium microphyllum) has become one of the most invasive and destructive weeds in southern Florida. To date different efforts have been made to control its growth and spread but have not been successful. In light of the highly delicate ecosystem affected by L. microphyllum, a biological paradigm may be a more ecologically sound approach to the containment of this obnoxious weed. …

Using Baits To Deliver Pharmaceuticals To Feral Swine In Southern Texas, Tyler A. Campbell, Steven J. Lapidge, David B. Long

USDA Wildlife Services: Staff Publications

Few studies have evaluated oral delivery systems of pharmaceuticals (e.g., vaccines, fertility control agents, and toxicants) to feral swine (Sus scrofa) in the United States. Our objective was to assess, through a field trial, the percentage of feral swine and non-target animals that remove and consume baits intended to transport pharmaceuticals to feral swine in southern Texas, USA. We hand-placed 1,178 iophenoxic acid (IA)–marked baits distributed over 1,721 ha (68 baits/km²) in April 2005 and monitored species-specific bait removal and consumption using track stations, automated camera systems, and serum IA values from captured animals. Ninety percent …

The Biology Of Introduced Norway Rats On Kiska Island, Alaska, And An Evaluation Of An Eradication Approach, Gary W. Witmer, Patrick Burke, Susan Jojola, Peter Dunlevy

USDA Wildlife Services: Staff Publications

Introduced, invasive rats can cause substantial damage to native flora and fauna, including ground-nesting seabirds, when they become established on islands. We tested a control method for introduced Norway rats on Kiska Island, Alaska, during April-May, 2004, by hand-broadcasting rodenticide pellets (0.005% diaphacinone) over a 4-ha area at the rate of 28 kg/ha. We also gathered data on aspects of rat ecology and distribution, although rats were difficult to detect and capture. The rodenticide bait pellets seemed to have been effective in reducing the Norway rat population, however, this is based on a limited observation of rat sign and captures. …
