Aquatic Diversity In A Changing Tropical Andean Glacierized Catchment: Macroinvertebrates Reveal Possible Important Consequences To The Chimborazo Region As Glaciers Recede And The Climate Continues To Change, Tanner Thomas
Independent Study Project (ISP) Collection
Tropical Andean glaciers are retreating rapidly, and their disappearance will have drastic consequences for the people and ecosystems that depend on them. While they have begun to receive the attention they deserve in scientific literature, much is still not known. Majority of these investigations have taken place on the Volcán Antisana, while other important glacierized systems, like the Volcán Chimborazo have received little attention. This investigation aimed to a) evaluate the possible effects of glacier loss and climate change on aquatic ecosystems by comparing glacial meltwater, non-glacial and mixed streams, and b) to evaluate the effects of pasture intensity on …
Changing Water Resources’ Effect On Livelihoods And Socio-Ecological Relationships In Himalayan Communities Of Nepal, Luke Bazemore
Changing Water Resources’ Effect On Livelihoods And Socio-Ecological Relationships In Himalayan Communities Of Nepal, Luke Bazemore
Independent Study Project (ISP) Collection
The looming threat of climate change will lead to significant alterations in livelihoods and daily practices for individuals across the world. This paper seeks to identify the effects of climate change on hydrological regimes in Himalayan communities in Nepal with particular focus towards livelihood and socio-ecological transformations. Using the socio-ecological systems framework to analyze specific communities and their resource use, along with vulnerability and adaptative capacity analysis, this paper includes a meta-analysis of existing literature. Numerous findings indicated that rural, mountainous communities of Nepal face a variety of environmental impacts which may reduce viability of two significant modes of production: …
The Relationship Between Forest Management And Stream Discharge In Mazumbai And Baga Ii Forest Reserves, Tanga Region, Tanzania, Shannon Duffy
The Relationship Between Forest Management And Stream Discharge In Mazumbai And Baga Ii Forest Reserves, Tanga Region, Tanzania, Shannon Duffy
Independent Study Project (ISP) Collection
Deforestation is known to alter hydrology by reducing interception, transpiration and infiltration capacity, and increasing runoff which all leads to higher stream discharge. For rural Tanzanian communities, surface water resources are crucial for meeting basic needs, so the integrity of headwater catchments need to be maintained to ensure their reliability. The objectives of this study were to a) map the streams in the two forests because none currently exist and b) determine the effect of deforestation on discharge variability. Over fifteen days of data collection, this study analyzed variability of discharge and the degree of correlation between discharge and rainfall …
