Ethnobiology In The City: Embracing The Urban Ecological Moment, Marla R. Emery, Patrick T. Hurley

Environment and Sustainability Faculty Publications

More than half the world's human population resides in cities (United Nations Economic and Social Affairs Population Division 2015). Unpacking this singular statistic, it becomes clear that people come to live in urban environments via numerous routes. Some have lived in cities all their lives and are descendants of city dwellers. In other cases, cities spread and encircle them (Hurley et al. 2008; Unnikrishnan and Nagendra 2015). Increasingly, rural residents are national and transnational migrants to cities, pushed by armed conflict, natural disasters, and economic need or opportunity (United Nations Economic and Social Affairs Population Division 2013). In the case …

A Note On The Temporary Misregistration Of Landsat-8 Operational Land Imager (Oli) And Sentinel-2 Multi Spectral Instrument (Msi) Imagery, James Storey, David P. Roy, Jeffrey Masek, Ferran Gascon, Michael Choate

GSCE Faculty Publications

The Landsat-8 and Sentinel-2 sensors provide multi-spectral image data with similar spectral and spatial characteristics that together provide improved temporal coverage globally. Both systems are designed to register Level 1 products to a reference image framework, however, the Landsat-8 framework, based upon the Global Land Survey images, contains residual geolocation errors leading to an expected sensor-to-sensor misregistration of 38 m (2σ). These misalignments vary geographically but should be stable for a given area. The Landsat framework will be readjusted for consistency with the Sentinel-2 Global Reference Image, with completion expected in 2018. In the interim, users can measure Landsat-to-Sentinel tie …

No. 05: Mapping The Informal Food Economy In Cape Town, South Africa, Jane Battersby, Maya Marshak, Ncedo Mngqibisa

Hungry Cities Partnership

The informal food retail sector is an important component of urban food systems and plays a vital role in ensuring access to food by the urban poor. Yet, policy frameworks both to address food security and to govern the informal sector neglect informal retail in the food system and, as a result, the sector is poorly understood. This discussion paper argues that it is essential to understand the dynamics of the informal food retail sector, which is diverse in terms of products traded as well as the business models utilized. The paper attempts to identify the characteristics of the sector …

Remote Sensing Of Snow Using Bistatic Radar Reflectometry, Abi Komanduru

Open Access Theses

Snow and ice processes are a critical part of the Earth’s hydrological and climate cycles. These processes can serve as an important source of fresh water as well as a cause of flooding. Various missions have been proposed by NASA and ESA for the purpose of remote sensing of snow. This research looks at applying bistatic radar reflectometry to the remote sensing of snow water equivalent. The resulting phase offset from changes in optical path length due to reflection through snow are the primary measurements made. The research uses data from a field campaign in Fraser, CO, involving an instrument …

Mean Hydroclimatic And Hydrological Conditions During Two Climatic Modes In The Devils Lake Basin, North Dakota (Usa), Paul E. Todhunter

Geography & Geographic Information Science Faculty Publications

Proxy variables from palaeolimnological studies of lakes in the Prairie Pothole Region of North America have been used to infer large oscillations during the late Holocene between longer periods of high-salinity–dry conditions and shorter periods of low-salinity–wet conditions producing a normative pattern marked by the absence of hydrological stability. Studies of the historical rise in lake level at Devils Lake have identified 1980 as a transition point between two such hydroclimatic modes. This study uses multiple datasets to characterize the mean hydroclimatological and hydrological conditions of these two climatic modes. Mode 1 is a cool and dry phase, and mode …

Quantifying Terrestrial Ecosystem Carbon Dynamics With Mechanistically-Based Biogeochemistry Models And In Situ And Remotely Sensed Data, Shaoqing Liu

Open Access Dissertations

Terrestrial ecosystem plays a critical role in the global carbon cycle and climate system. Therefore, it is important to accurately quantify the carbon dynamics of terrestrial ecosystem under future climatic change condition. This dissertation evaluates the regional carbon dynamics by using upscaling approach, mechanistically-based biogeochemistry models and in situ and remotely sensed data.

The upscaling studies based on FLUXNET network has provided us the spatial and temporal pattern of the carbon fluxes but it fails to consider the atmospheric CO2 effect given its important physiological role in carbon assimilation. In the second chapter, we consider the effect of atmospheric CO2 …

Fleeing To Fault Zones: Incorporating Syrian Refugees Into Earthquake Risk Analysis Along The East Anatolian And Dead Sea Rift Fault Zones, Bradley Wilson

Graduate Theses and Dissertations

The influx of millions of Syrian refugees into Turkey has rapidly changed the population distribution along the Dead Sea Rift and East Anatolian Fault zones. In contrast to other countries in the Middle East where refugees are accommodated in camp environments, the majority of displaced individuals in Turkey are integrated into local cities, towns, and villages—placing stress on urban settings and increasing potential exposure to strong earthquake shaking. Yet, displaced populations are not traditionally captured in data sources used in earthquake risk analysis or loss estimations. Accordingly, this study presents a district-level analysis assessing the spatial overlap of earthquake hazards …

An Integrated Approach For A Better Understanding Of The Paleo-Hydrology And Landscape Evolution In The Sahara During The Previous Wet Climatic Periods, Abotalib Zaki Abotalib Farag

Dissertations

Paleoclimatic regimes over Saharan Africa alternated between dry and wet periods throughout the Pleistocene Epoch, and it is during the wet periods that the Saharan fossil aquifers were recharged. The present study investigates the role of groundwater-related processes in shaping the Saharan landforms (e.g., theater-headed valleys [THV]; depressions, escarpments, playas, and tufa deposits) over areas occupied by the largest of these aquifer systems, the Nubian Sandstone Aquifer System (NSAS). The present study reviews the suggested hypotheses for the origin of these landforms in the Sahara, and in similar settings elsewhere, and presents evidence in support of the following: during the …
