Managing The Environmental And Socio-Economic Impacts Of Rohingya Refugees In Bangladesh, Mousume Azad

Master's Projects and Capstones

In August 2017, nearly 1 million Rohingya people fled to Bangladesh to save their lives from the genocide inflicted by the military of Myanmar. At present, over 1.3 million Rohingyas are staying at Cox’s Bazar, Bangladesh, in 34 overcrowded refugee camps. This research examined the environmental impacts especially the change in vegetation cover and land surface temperature as well as the socioeconomic alteration of the host country after the refugee influx. The research found a 5488 ha or 9.58% decrease in forest area, accompanied by an 8.25% increase in refugee settlement areas, an increase in average land surface temperature within …


Improving The Land Trust Model’S Impact On Environmental Conservation In Northern California, Peter Talbot Jun 2023

Improving The Land Trust Model’S Impact On Environmental Conservation In Northern California, Peter Talbot

Master's Projects and Capstones

For years, the land trust sector of California and much of the United States has operated with a dollars and acres mentality that has prioritized fundraising as a result of acreage protected. Within California, nearly 5.8 million acres of land have been protected by 132 land trusts throughout the state. To accommodate for the diverse cross-section of land and the many needs of the population, land trusts take on numerous shapes and sizes. A unique aspect of this diversity is the rich agricultural and natural spaces found throughout the state. This mix of land and variety of land uses has …


Considerations For The Use Of Mycorrhizal Fungi Inoculants In Coal Mine Reclamation And Reforestation In Appalachia: A Guide Of Best Practices And Management Recommendations, Cole Hansen Reistrup May 2023

Considerations For The Use Of Mycorrhizal Fungi Inoculants In Coal Mine Reclamation And Reforestation In Appalachia: A Guide Of Best Practices And Management Recommendations, Cole Hansen Reistrup

Master's Projects and Capstones

Nearly all terrestrial plants form symbiotic relationships with mycorrhizal fungi. These beneficial soil microbes support plant health by increasing plants’ access to nutrients and water, protecting them from pathogens, improving soil properties, and more. A challenge to restoring forests on coal mined land in Appalachia is that mine soils are often degraded in a number of ways, including lacking mycorrhizal fungi, which makes mine soils difficult for trees to grow upon. Substantial improvements to coal mine reforestation success have been made since the development of the Forestry Reclamation Approach in 2005 that provides guidelines for how to create a suitable …


Assessing The Efficacy Of California’S Wildfire And Forest Resilience Action Plan, Chloe Nelson May 2022

Assessing The Efficacy Of California’S Wildfire And Forest Resilience Action Plan, Chloe Nelson

Master's Projects and Capstones

California’s wildfire threat eclipses current forestry management and wildfire mitigation strategies in place to protect people, infrastructure, and the natural environment. Climate change escalates wildfire risks with declining water supply coupled with hotter, drier conditions. California’s Wildfire and Forest Resilience Action Plan attempts to integrate and build upon previously successful wildfire resilience plans to amplify the scale and pace of the state’s land management and community protections. This research assesses the plan’s efficacy to respond to the growing wildfire threat. This study investigates if there is equitable planning for the needs of high-wildfire risk groups living in the WUI and …


The Relationship Between Forest Fires And Forest Dynamics In California’S North Coast Bioregion: How Altered Fire Regimes Have Affected The Vegetative Outcomes Of Oak Woodlands And Mixed Conifer Forests, Max Bencomo May 2020

The Relationship Between Forest Fires And Forest Dynamics In California’S North Coast Bioregion: How Altered Fire Regimes Have Affected The Vegetative Outcomes Of Oak Woodlands And Mixed Conifer Forests, Max Bencomo

Master's Projects and Capstones

Wildfire is a necessary part of ecosystem function in California, but fire suppression and the spread of invasive species have endangered many ecosystems. The North Coast bioregion of California has seen dramatic shifts in forest ecology and vegetative density, largely due to the disruption of historic fire regimes. Historic fire regimes were previously maintained through indigenous land management, but the arrival of European settlers in the 1850’s initiated the changes reflected in current fire regimes. Not only is the North Coast bioregion the hotbed of recent fire activity, it is experiencing decreased counts of heterogeneity within forests while also seeing …


A Comparison Of Fuel Reduction Methods For Wildfire Risk Management And Climate Change Resiliency In Mixed Conifer Forests In The Sierra Nevada, Heather Navle May 2020

A Comparison Of Fuel Reduction Methods For Wildfire Risk Management And Climate Change Resiliency In Mixed Conifer Forests In The Sierra Nevada, Heather Navle

Master's Projects and Capstones

Wildfires in the mixed conifer forests of California’s Sierra Nevada have been a common and natural disturbance for thousands of years, historically occurring every 3 to 30 years. The flora and fauna of the mixed conifer forest have evolved to depend on low to moderate severity wildfires for reproduction, foraging, and habitat. However, the Sierra Nevada has experienced dramatic environmental changes over the past ~150 years as a result of three main factors: wildfire suppression, climate change, and habitat loss. Because of the threat wildfires pose to human lives, property and timber harvest, they have been suppressed to an extent …


The Mexican Water Forest: Benefits Of Using Remote Sensing Techniques To Assess Changes In Land Use And Land Cover, Maria F. Lopez Ornelas May 2016

The Mexican Water Forest: Benefits Of Using Remote Sensing Techniques To Assess Changes In Land Use And Land Cover, Maria F. Lopez Ornelas

Master's Projects and Capstones

In the past 30 years, anthropogenic activities like urbanization, agriculture, road fragmentation and deforestation have resulted in changes in the land use and land cover (LULC) in the Mexican Water Forest. Due to the important ecosystem services, and the natural resources this forest provides, in Mexico, it has become increasingly necessary to use new technologies and tools to support the planning, implementation and integration of forest management and conservation plans, as well as ecological and socioeconomic analysis of this ecosystem. Remote Sensing techniques and Geographic Information Systems (GIS) have been a true technological and methodological revolution in the acquisition, management …


The Role Of The State, Multinational Oil Companies, International Law & The International Community: Intersection Of Human Rights & Environmental Degradation Climate Change In The 21st Century Caused By Traditional Extractive Practices, The Amazon Rainforest, Indigenous People And Universal Jurisdiction To Resolve The Accountability Issue, Marcela Cabrera Luna Dec 2015

The Role Of The State, Multinational Oil Companies, International Law & The International Community: Intersection Of Human Rights & Environmental Degradation Climate Change In The 21st Century Caused By Traditional Extractive Practices, The Amazon Rainforest, Indigenous People And Universal Jurisdiction To Resolve The Accountability Issue, Marcela Cabrera Luna

Master's Theses

Local, national and international conventions that protect indigenous sovereignty and their territories, where many of the resources are extracted from by multinational corporations (MNCs) particularly oil, the number one commodity of the world and cause of climate change, continue to be jeopardized because of the lack of a clear international legal framework that can protect them and potentially hold multinationals accountable for their actions. These practices are causing not only environmental issues to the indigenous and surrounding communities, but climate change is in fact, the real human rights issue of the 21st century and it affects everyone. By using …


Evaluation Of Methods For Control Of Vegetation In Utility Corridors, George V. Rancea May 2014

Evaluation Of Methods For Control Of Vegetation In Utility Corridors, George V. Rancea

Master's Projects and Capstones

Vegetation management programs are now one of the largest budget items for most of the utility companies in the United States. Control methods used in line clearance activities include mechanical trimming, planting management, or use of tree growth regulators (chemicals that suppress the production of gibberellins, the plant hormones that control stem elongation). Choosing the appropriate control method is a decision that vegetation program managers should take based on many factors, like costs, environmental impacts, existing agreements with the landowners, terrain, public perception etc. To find a balance between competing interests – a reliable and economic electric system on one …


Using Field Data To Assess Model Predictions Of Surface And Ground Fuel Consumption By Wildfire In Coniferous Forests Of California, J M. Lydersen, B M. Collins, C M. Ewell, A L. Reiner, J A. Fites, C B. Dow, P Gonzalez, David Saah, J J. Battles Jan 2014

Using Field Data To Assess Model Predictions Of Surface And Ground Fuel Consumption By Wildfire In Coniferous Forests Of California, J M. Lydersen, B M. Collins, C M. Ewell, A L. Reiner, J A. Fites, C B. Dow, P Gonzalez, David Saah, J J. Battles

Environmental Science

Inventories of greenhouse gas (GHG) emissions from wildfire provide essential information to the state of California, USA, and other governments that have enacted emission reductions. Wildfires can release a substantial amount of GHGs and other compounds to the atmosphere, so recent increases in fire activity may be increasing GHG emissions. Quantifying wildfire emissions however can be difficult due to inherent variability in fuel loads and consumption and a lack of field data of fuel consumption by wildfire. We compare a unique set of fuel data collected immediately before and after six wildfires in coniferous forests of California to fuel consumption …
