Recent evidence suggests that urban forms and materials can help to mediate temporal variation of microclimates and that landscape modifications can potentially reduce temperatures and increase accessibility to outdoor environments. To understand the relationship between urban form and temperature moderation, we examined the spatial and temporal variation of air temperature throughout one desert city—Doha, Qatar—by conducting vehicle traverses using highly resolved temperature and GPS data logs to determine spatial differences in summertime air temperatures. To help explain near-surface air temperatures using land cover variables, we employed three statistical approaches: Ordinary Least Squares (OLS), Regression Tree Analysis (RTA), and Random Forest …


Bioswales For Stormwater Remediation And Infiltration: Assessing Regulatory Climate And Quantifying Filtration Capacity Of A Claremont Bioswale, Skyler Lewis, Boyu Liu, Paul Picciano, Liana Solis, Char Miller May 2016

Watershed management is critical in ensuring a sustainable water supply. This project is designed to assess the impact of bioswales in the context of Southern California’s climate. The patterns of droughts and floods make these green infrastructure appealing as they offer potential to boost water quality and regenerate local aquifers, while reducing the area of impermeable surfaces in our urban landscape. As bioswales have not been commonly incorporated into infrastructure development, our project focuses on a relatively new bioswale, added in 2012 and located on Pomona College’s campus, to serve as our case study in determining the viability of bioswales …

Sustainable watershed management (SWM) can be achieved through recognition and reflection upon the values of citizens. Collaborative governance consisting of citizens is crucial for successful SWM. Collaborative governance definitely requires an active participatory decision-making process that reflects citizens’ preferences. Citizen preference also tends to substantially change with life pattern and life quality. These shifts can be caused by slight variations in both social priorities and personal preferences for SWM. Therefore, collaborative water governance must be frequently renewed in response to citizens’ values through the participatory framework. The An’yang Stream in South Korea is generally regarded as a representative urban stream …

We analyzed the impact of amenity and biodiversity protection as mandated in national forest plans on the implementation of hazardous fuel reduction treatments aimed at protecting the wildland urban interface (WUI) and restoring fire resilient forests. We used simulation modeling to delineate areas on national forests that can potentially transmit fires to adjacent WUI. We then intersected these areas with national forest planning maps to determine where mechanical treatments are allowed for restoration and fire protection, versus areas where they are prohibited. We found that a large proportion of the national forest lands (79%) can spawn fires that burn adjacent …


Micrometeorological Simulations To Predict The Impacts Of Heat Mitigation Strategies On Pedestrian Thermal Comfort In A Los Angeles Neighborhood, Mohammad Taleghani, David J. Sailor, George A. Ban-Weiss Feb 2016

The urban heat island impacts the thermal comfort of pedestrians in cities. In this paper, the effects of four heat mitigation strategies on micrometeorology and the thermal comfort of pedestrians were simulated for a neighborhood in eastern Los Angeles County. The strategies investigated include solar reflective ‘cool roofs’, vegetative ‘green roofs’, solar reflective ‘cool pavements’, and increased streetlevel trees. Aseries of micrometeorological simulations for an extreme heat day were carried out assuming widespread adoption of each mitigation strategy. Comparing each simulation to the control simulation assuming current land cover for the neighborhood showed that additional street-trees and cool pavements reduced …


Precolonial Institutions And Deforestation In Africa, S. Larcom, Terry Van Gevelt, A. Zabala Feb 2016

Precolonial Institutions And Deforestation In Africa, S. Larcom, Terry Van Gevelt, A. Zabala

Research Collection College of Integrative Studies

We find that local institutions inherited from the precolonial era continue to play an important role in natural resource governance in Africa. Using satellite image data, we find a significant and robust relationship between deforestation and precolonial succession rules of local leaders (local chiefs). In particular, we find that those precolonial areas where local leaders were appointed by ‘social standing’ have higher rates of deforestation compared to the base case of hereditary rule and where local leaders were appointed from above (by paramount chiefs). While the transmission mechanisms behind these results are complex, we suggest that areas where local leaders …

Urban greenery is a favoured approach applied towards reducing urban warmth and climate discomfort, but ascertaining its measured and perceived effectiveness in tropical climates is relatively understudied. To this end, we investigated microclimate differences within an urban park (the Singapore Botanic Gardens) to assess if variations in plot-scale land cover affect both objective (measured) and subjective (surveyed) microclimate data. Over two monsoonal seasons, we obtained data from four distinct sites—a tropical rainforest stand, a palm tree valley, a water-body feature, and the park visitors’ centre. Measured climate data (e.g. air temperature, vapour pressure, wind velocity and globe temperatures) were used …
