Drought is a period of abnormally dry weather that leads to hydrological imbalance. Drought assessments determine the characteristics, severity, and impacts of a drought. Climate change adds conceptual and quantitative challenges to traditional drought assessments. This paper highlights the challenges of assessing drought in a climate made non-stationary by human activities or natural variability. To address these challenges, we then identify 10 key research priorities for advancing drought science and improving assessments in a changing climate. The priorities focus on improving drought indicators to account for non-stationarity, evaluating drought impacts and their trends, addressing regional differences in non-stationarity, determining the …

Forest Carbon Modeling Improved Through Hierarchical Assimilation Of Pool-Based Measurements, Yu Zhou, Christopher A. Williams
Geography
Accurate assessment of forest carbon dynamics is a critical element of appraising forest-based Natural Climate Solutions. National forest inventory and analysis (FIA) data provide valuable pool-based estimates of carbon stocks, but have been underutilized to inform carbon cycle modeling for forest carbon dynamics with stand development. This study introduces a hierarchical data assimilation (HDA) framework to optimize modeling parameters by incrementally assimilating measured carbon pool data into the model. We found that most carbon stocks could be reproduced by constrained parameters after each HDA step. Using aboveground live biomass (AGB) alone in HDA was able to reproduce the AGB trajectories …

When Civil Society Defends Authoritarianism: Thai Bhakdi, We Support Prayuth, And Thailand’S Democratic Decline, Igastya Hagarayu Sapta, Luthfi Makhasin
Jurnal Politik
Civil society is often regarded as an essential foundation for democratic consolidation, but in Thailand, civil society also plays a crucial role in maintaining authoritarian rule. This article analyzes how pro-authoritarian civil society movements—Thai Bhakdi and “We Support Prayuth”—emerged and operated in the context of the historical relationship between the military and the monarchy and political polarisation since the 2006 coup. Using the authoritarian civil society (ACS) framework and a comparative historical analysis approach, this study traces how the long-standing divide between reformist and conservative forces created fertile ground for these movements. Thai Bhakdi, rooted in monarchist nationalism, …

The Fading Of Identity Politics And The Rise Of Oligarchy In Selayar, South Sulawesi, Abu Bakar, Gustiana A. Kambo, M. Teguh Setyadi Bahtiar
Jurnal Politik
The fading of identity issues indicates that the direction of local politics in Selayar has shifted and changed. However, this change does not mean that it does not bring new problems to the local political landscape in Selayar, South Sulawesi, Indonesia. We aim to uncover the emergence of oligarchy in place of identity politics as a new phenomenon in the Selayar context. This research uses the concept of oligarchy to understand it, which is described qualitatively. In general, we argue that the failure of identity politics to consolidate power has given birth to oligarchies that are intertwined with familism in …

Notch Formation Due To Freeze-Thaw Action In The North-Facing Valley Cliff Of The Asama Volcano Region, Japan, Yukinori Matsukura
The Geographical Bulletin
There are notches at the base of vertical cliffs located at the foot of Asama Volcano, Japan. In the north-facing cliff, frost weathering is frequently observed on the notch surface in winter. Mean air temperature is below freezing point in winter. There are many fine days in winter, but the sunshine cannot hit the northfacing cliff due to its orientation. These conditions gradually cool the notch zone and make a frozen layer which grows parallel to the notch surface. The maximum frost penetration depth is estimated to be 20 to 30 cm in one winter season. Exfoliation occurs in spring …

Factors Controlling Ground Water Flow To Wells In Crystalline Rocks Based On A Principal Components Analysis, Southeastern Piedmont Of Georgia, Joseph E. Garcia, George A. Brook
The Geographical Bulletin
In a study of the geologic and topographic factors influencing well productivity in the crystalline southern Piedmont region of Georgia, Garcia et al. (1990) found that three variables explained 65 percent of the variation in well productivity. However, many of the nine variables examined could not be included in modeling because of high intercorrelation detracting from the interpretive if not the predictive value of the result. To overcome this problem, data from Garcia et al. (1990) were subjected to a principal components analysis. This technique was used to transform the set of nine highly correlated variables into three uncorrelated components. …

Spatial Patterns Of Visitor Behavior: A Case Study Of The North Carolina Zoological Park, Maurice L. Mckenzie, Keith G. Oebbage
The Geographical Bulletin
This paper explains the spatial patterns of visitor behavior at the North Carolina Zoological Park (NCZP). The NCZP is one of the top ten tourist attractions in the state, but it is unclear what factors influence each individual's decision to visit the zoo. The research reported in this paper partially confirmed many of the theoretical expectations about visitor behavior. Based on the results of a visitor survey, the NCZP is a family attraction that caters to a largely well-educated and affluent audience. Most of those surveyed came from the nearby urban centers, while the rural counties immediately adjacent to the …

The Geography Of Rockfall Hazards In Glacier National Park, Montana, David R. Butler
The Geographical Bulletin
Glacier National Park, Montana, has a long history of falling rock and rockfall accidents. The recent history of rockfall activities and accidents in the Park is documented here. Rockfalls are frequent in spring and autumn months, when temperatures fluctuate across the freezing point. Summer rockfall activity is primarily associated with heavy rainfall. Hazardous rockfalls may occur on any slope aspect, especially in areas where stratigraphic dip parallels the slope. Numerous accidents from falling rock have occurred, but are spatially concentrated in two major and two minor highway zones, as well as i., the backcountry. Visitors to the Park are effectively …

All of us remember the favorite sayings of some of our teachers. When I was a first-year student at the University of the Witwatersrand, Professor J. H. Wellington would start many a lecture by stating "Geography is a field science. What I am about to tell you comes from my field notes. When you go on to graduate school, your success or failure will depend on your ability to do original field research." When I was in the Master's degree program at Northwestern University, a visiting professor, A. E. Moodie, liked to say that "If you cannot map it, it …

Native Texans' Perception Of Yankees, Byron D. Augustin, Dennis E. Fitzsimons
The Geographical Bulletin
Texas now ranks as the third most populous state in the United States. Over the past 40 years, much of the population growth can be attributed to migration from outside the state's boundaries. Not all native Texans look favorably on the new growth patterns. "Yankee" is a term which some native Texans tend to label any new resident who does not enter from Mexico. The purpose of this paper is to delineate those states which are perceived by native Texans to produce Yankees. A second goal is to provide insight into the perception that native Texans have regarding the word …

Heat Island Of The Akron Canton Regional Airport, Ohio, Nirmala Kochar, Thomas W. Schmidlin
The Geographical Bulletin
Air temperatures measured by the National Weather Service at rural airports may not represent the temperatures of the surrounding rural areas because of extensive paved surfaces, buildings, sparse vegetation, and the flow of surface traffic at the airport. These factors may cause the presence of a heat island which is generally an urban phenomenon. The temperature and wind of the Akron-Canton Airport and eight nearby rural sites was studied between December 1987 and October 1988. The results showed that the airport was a heat island for 83% of the calm, clear evenings. An airport heat island did not exist under …

Comparison Of Temporal Differences In Models Of Soil Moisture And Plant Biomass Variability In The Southern Great Plains Of The United States, Stephen J. Walsh
The Geographical Bulletin
Multiple regression models of soil moisture at 15, 61, and 91 cm depths, and for above-ground plant biomass explained 92, 90, 92, and 88 percent of the variability, respectively, through field data collected in 1986. Multiple regression models developed for soil moisture and plant biomass, through data collected in 1985, answered 83, 91, and 82 percent, and 85 percent of the variability, respectively. Field data were collected along a 200 km transect in west-central Oklahoma from May through August 1985 and 1986: four sites were eliminated in 1986 and sampling was changed from weekly to bi-weekly. Air temperature, precipitation levels, …

Research Needs In Physical Geography, Melvin G. Marcus
The Geographical Bulletin
The future of research in physical geography is assessed and discussed. The discussion is divided into three parts: the inevitable generalization and comments on geography; geography's share of research funds; and critical research objectives for the future are selectively surveyed. The comments are hopefully not solely limited to physical geography but to geography in general. In spite of technical innovations the writer suggests field studies, regional information and an assessment of older data ought to be undertaken.
