Degree Of Sedentarization Affects Risks And Conflicts For The Waso Boran In Northern Kenya, D. Layne Coppock, Abdullahi D. Jillo, Mark N. Mutinda, Abdilla A. Aboud
Degree Of Sedentarization Affects Risks And Conflicts For The Waso Boran In Northern Kenya, D. Layne Coppock, Abdullahi D. Jillo, Mark N. Mutinda, Abdilla A. Aboud

The Waso Borana have lived for over a century in northern Kenya. In the last few decades, however, their ability to maintain their traditions has been severely challenged. Here we report survey results from 540 households in Isiolo District, stratified among three groups differing in terms of lifestyle: sedentary, semi-sedentary, and mobile. In some cases these groups vary with respect to important perceived risks, causes of natural-resource related conflict, and possible solutions to conflict. For example, sedentary respondents often noted concerns over land tenure problems, human diseases, and political incitement. Mobile respondents, in contrast, often noted primary concerns over drought, …

Indigenous to Peru, Chile, and Argentina, the woody plant called Prosopis juliflora (also known by the American common name of “Honey Mesquite”) has spread world-wide in recent decades, including rangelands throughout Latin America, North America, south and central Asia, Australia, and sub-Saharan Africa. A species known for rapid establishment, high adaptability, and fast rates of growth, its dispersal has primarily been a consequence of intentional introduction by well- meaning “technical experts” who wanted to provide a new source of fodder, fuel wood, or a means to combat desertification in arid and semi-arid lands. One problem, however, is that unless Prosopis …
Linking Pastoralists And Exporters In A Livestock Marketing Chain: Recent Experiences From Ethiopia, D. Layne Coppock, Solomon Desta, Getachew Gebru, Seyoum Tezera
Linking Pastoralists And Exporters In A Livestock Marketing Chain: Recent Experiences From Ethiopia, D. Layne Coppock, Solomon Desta, Getachew Gebru, Seyoum Tezera

The Boran of southern Ethiopia have been traditionally viewed as unwilling or unable to engage in large scale, commercialized livestock trade. Here we report on the creation of a new livestock marketing chain from the Borana Plateau to export outlets largely serving the Gulf States. Since 2003 various meetings and exchange tours were organized by collaborating agencies and PARIMA to directly link pastoral producers with livestock exporters and policy makers. This occurred against a backdrop of growing export demand for small ruminants, rapid development of private export industry, formation of well-trained pastoral marketing groups (often dominated by women), and provision …

Continuing Analysis Of Phytoplankton Nutrient Limitation In Farmington Bay And The Great Salt Lake, Wayne A. Wurtsbaugh, Amy M. Marcarelli
Continuing Analysis Of Phytoplankton Nutrient Limitation In Farmington Bay And The Great Salt Lake, Wayne A. Wurtsbaugh, Amy M. Marcarelli
Watershed Sciences Faculty Publications
Farmington Bay is a nutrient-enriched, highly eutrophic embayment of the Great Salt Lake. The highly variable salinity of the bay influences what species of plankton can survive there. Previous analyses suggested that cyanobacteria (blue-green algae) may not be able to survive or fix atmospheric nitrogen at high salinities, thus maintaining the lake in a nitrogen-limited state. To determine the interacting influence of nutrients and salinity on the growth and nitrogen fixation of plankton we performed a 28-day bioassay with water from Farmington and Gilbert Bays in October 2004. We tested the response of the plankton to additions of nitrogen (N) …
Ecological Analysis Of Nutrient, Plankton And Benthic Communities In Farmington Bay And The Great Salt Lake, Utah (2004), Amy M. Marcarelli, Wayne A. Wurtsbaugh

In Fall 2004, the Aquatic Ecology Practicum class at Utah State University finished a third year of research on limnological and ecological characteristics of Farmington Bay and Gilbert Bays of the Great Salt Lake. Our previous research has produced interesting findings in Farmington Bay, including hypereutrophy (Marcarelli et a!. 2001), high phosphorus loading into the Bay, overnight water column anoxia linked to high winds (Wurtsbaugh et a!. 2002), potential predator control of brine shrimp, and high levels of hydrogen sulfide in the sediment and deep brine layer (Marcarelli et a!. 2003). These class findings have lead to increased interest in …

In glaciated mountains, lakes are interspersed through watersheds and connected by streams. Although lakes or streams are frequently studied as individual water bodies, studying them as integrated functional units provides considerable insight on temperature patterns, nutrient transport and other functions. In the Sawtooth Mountains (Idaho), inter-lake distance averages 2.8 km. In summer, lakes are solar collectors, and warm outflow streams as much as 10 C, thus increasing metabolic rates. These streams seldom cool to equilibrium temperatures before encountering another lake, where the waters tend to overflow and mix into the epilimnion. With overflow, N-15 tracer experiments demonstrated that water and …
