Forest Loss Trajectories and Palm Oil Extent in Indonesia
Tropical forests provide critically important ecosystem services, and they are particularly important for their levels of biodiversity and for the carbon that they store. Yet despite global efforts to slow or halt deforestation, natural forests in the tropics continue to be cleared, primarily for …

Using real-time forest loss alerts and global deforestation maps to assess the effectiveness of Africa's tropical protected areas
Tropical rainforests harbor a significant portion of the world's remaining biodiversity. Having undergone rapid changes in forest cover over the last two decades, a large amount of irreplaceable biodiversity has been lost. The establishment of protected areas has been a key strategy to hinder the …

China's Forest Product Imports and the Impacts on Tropical Forests
China's forest product imports have surged over the past two decades, fueled by robust economic growth and an inadequate domestic timber supply. In 2017, China implemented a complete logging ban in its natural forests, further widening the domestic timber supply gap. Many observers highlight the …

A Holistic Analysis for Spatiotemporal Interdependencies of Deforestation, Forest Degradation and Landslide Susceptibility in NE Iran
Various biotic and abiotic agents are changing forests. Prolonged human activities substantially could cause not only different changes in forests but also could accelerate natural hazards in the Anthropocene. Despite several remote sensing-based research in forest changes, there is a need for a …

A Global GIS Analysis of Primate Diversity and Biogeography: Assessing Trends in Habitat Loss and Extinction Risk to Inform Primate Conservation
… concentrated in the tropics, and tropical rainforests in particular. Tropical tree cover loss is therefore central to the biodiversity crisis, and unfortunately it is continuing at alarming rates and showing no signs of slowing. This forest loss severely impacts primates, which are one of the …

Impact of environmental law enforcement on deforestation, land use and natural regeneration in the Brazilian Amazon
… arisen as a result of climate change and the loss of tropical forests. Indeed, these challenges present two of the greatest environmental challenges of all time. Nevertheless, Brazil has recently adopted policies that have greatly reduced forest loss over the past decade or more. A strong …

Risks to Global Primate Diversity from Climate Change and Other Pressures
… are widely threatened from the impact of deforestation and other human activities, with many species already facing high risk of extinction. Climate change poses an additional threat to the world's biota. However, the extent to which future climate change poses a risk to primates in …

Social norms, markets and land use in a developing country context
… this household cultivated crop area expansion on forest loss, I construct district-level panel data on annual forest loss and maize price variability from 2007 to 2018 across Ghana’s forest belt. The results indicate that approximately 0.50 percent of forested area in Ghana is lost annually for …

The Effectiveness of Protected Areas in Central Africa: A Remotely Sensed Measure of Deforestation and Access
For protected areas that are extensively forested, the rate of deforestation is one indicator of the integrity of the protected area, and the effectiveness of protected area management. The goal of this study was to examine the deforestation rate in protected areas in Central Africa. Using remote …

Mapping urban forest extent and modeling sequestered carbon across Chattanooga, TN using GIS and remote sensing
… experiencing rapid urbanization and subsequent losses to urban forest area. Using remote sensing and digital image processing, this research 1) applied supervised hybrid classification across Landsat imagery that quantified the extent of urban forest loss across Chattanooga between 1984 and …

Bird use of avocado farms and intact forest in the Dominican Republic
… an increase of avocado farms and a subsequent forest loss. We conducted point-count bird surveys to determine how avian species richness and diversity differ between avocado farms and intact forest, as well as how vegetation differences between farms and forests could impact bird use. We found …

Translating Climate Change Policy: The case of REDD+ in Ghana
The policy of Reducing Emissions from Deforestation and Degradation (REDD+) has been promoted at the global level as an innovative approach to reduce forest loss that contributes to about one-fifth of global climate change. My dissertation brings together theories of policy processes and political …

Comparing density analyses and carnivore ecology in Madagascar's southeastern rainforest
… is renowned for its biodiversity, but also for forest loss, fragmentation, and degradation, making it a global conservation priority. With few studies dedicated to Madagascar's carnivores, little is known about their ecology. My objectives were to 1) compare density estimation techniques …

Measuring tropical forest disturbance and regrowth with spaceborne lidar
The world’s tropical forests are vulnerable, facing threats of deforestation and anthropogenic disturbances, but they are also the site of enormous potential for forest growth. While these changes in tropical forest frontiers are widely agreed to have major implications for global carbon fluxes and …

Bat Activity Across Urban Forest Plantings in Lexington, Kentucky
Urbanization has led to major forest loss and negatively impacts ecosystem services. Urban reforestation efforts, such as Reforest the Bluegrass (RTB) in the Lexington-Fayette metropolitan area of Kentucky, have been implemented to address these negative effects, and to create habitat for …

Predicting biodiversity loss in insular neotropical forest habitat patches
Neotropical forests have experienced high rates of biodiversity loss as a result of burgeoning land-use changes. Habitat conversion into cropland, pastures, and more recently hydroelectric lakes, are leading drivers of forest loss and fragmentation of pristine forests in the world’s most biodiverse …

Dynamics of Forest Cover Extent, Forest Fragmentation and Their Drivers in the Lake Victoria Crescent, Uganda From 1989 to 2009
Despite the important values forests play in the tropics, sustainable forest management still remains a challenge as manifested through continued forest loss. The objective of this study was to provide information on the dynamics of forest cover and their drivers vital for enhancing sustainable …

Forests, Beetles, and Climates in British Columbia's Central Interior: Historical Geographies of Paradigm Change in Forest Science and Management, 1945 - Present
This dissertation explores forest science and management issues in the Central Interior of British Columbia through a historical-geographical lens. I gather evidence that illustrates the combined socio-ecological nature of forest loss, degradation and industrial (i.e., timber supply) crises in the …
