Critical Agrarian Studies In Theory And Practice, Marc Edelman, Wendy Wolford

Publications and Research

Abstract: In this introductory article we argue for renewed attention to life and labor on and of the land—or what we call the field of Critical Agrarian Studies. Empirically rich and theoretically rigorous studies of humanity’s relationship to “soil” remain essential not just for historical analysis but for understanding urgent contemporary crises, including widespread food insecurity, climate change, the proliferation of environmental refugees, growing corporate power and threats to biodiversity. The article introduces an innovative and varied collection of works in Critical Agrarian Studies and also examines the intellectual and political history of this broader field.

The Potential Of Forest Biomass Inversion Based On Vegetation Indices Using Multi-Angle Chris/Proba Data, Qiang Wang, Yong Pang, Zengyuan Li, Guoqing Sun, Erxue Chen, Wenge Ni-Meister

Publications and Research

Multi-angle remote sensing can either be regarded as an added source of uncertainty for variable retrieval, or as a source of additional information, which enhances variable retrieval compared to traditional single-angle observation. However, the magnitude of these angular and band effects for forest structure parameters is difficult to quantify. We used the Discrete Anisotropic Radiative Transfer (DART) model and the Zelig model to simulate the forest canopy Bidirectional Reflectance Distribution Factor (BRDF) in order to build a look-up table, and eight vegetation indices were used to assess the relationship between BRDF and forest biomass in order to find the sensitive …

Women In The Gis Profession, Livia Betancourt-Mazur, Jochen Albrecht

Publications and Research

In many technical professions, women are underrepresented. While a gender imbalance also has been assumed to exist in the realm of professional GIS, no data existed to corroborate it. The original survey presented here was developed by the authors to add both quantitative and qualitative research about the numbers and current experience of women in GIS to address this knowledge gap. A total of 484 women responded to the survey, providing a healthy sample size and a reliable and informative data set.

A key finding is that some 42 percent of women are, overall, not grossly underrepresented in the GIS …

An Iterative Approach To Ground Penetrating Radar At The Maya Site Of Pacbitun, Belize, Sheldon Skaggs, Terry G. Powis, Clara R. Rucker, George Micheletti

Publications and Research

Ground penetrating radar (GPR) surveys provide distinct advantages for archaeological prospection in ancient, complex, urban Maya sites, particularly where dense foliage or modern debris may preclude other remote sensing or geophysical techniques. Unidirectional GPR surveys using a 500 MHz shielded antenna were performed at the Middle Preclassic Maya site of Pacbitun, Belize. The survey in 2012 identified numerous linear and circular anomalies between 1 m and 2 m deep. Based on these anomalies, one 1 m × 4 m unit and three smaller units were excavated in 2013. These test units revealed a curved plaster surface not previously found at …

Indigenous Ecuadorian Mobility Strategies In The Clandestine Migration Journey, Victoria Stone-Cadena

Publications and Research

Based on testimonials of migration journeys of indigenous Cañaris from southern highland Ecuador, this paper examines strategies of mobility and social networking employed by migrants and facilitators in the human smuggling market. Following a series of economic crises in the late 1990s, Ecuadorian transnational migration increased significantly, with a 55.5 percent increase to the United States between 2000 and 2008, and staggering 12,150 percent increase to Spain between 1998 and 2005. This article focuses on the growth of a regional migration industry in the southern high-land region, and pays special attention to the roles of indigenous Cañari migrants and migration …

Impact Of Irrigation Method On Water Use Efficiency And Productivity Of Fodder Crops In Nepal, Ajay K. Jha, Razan Malla, Mohan Sharma, Jeeban Panthi, Tarendra Lakhankar, Nir Y. Krakauer, Soni M. Pradhanang, Piyush Dahal, Madan Lall Shrestha

Publications and Research

Improved irrigation use efficiency is an important tool for intensifying and diversifying agriculture in Nepal, resulting in higher economic yield from irrigated farmlands with a minimum input of water. Research was conducted to evaluate the effect of irrigation method (furrow vs. drip) on the productivity of nutritious fodder species during off-monsoon dry periods in different elevation zones of central Nepal. A split-block factorial design was used. The factors considered were treatment location, fodder crop, and irrigation method. Commonly used local agronomical practices were followed in all respects except irrigation method. Results revealed that location effect was significant (p < 0.01) with highest fodder productivity seen for the middle elevation site, Syangja. Species effects were also significant, with teosinte (Euchlaena mexicana) having higher yield than cowpea (Vigna unguiculata). Irrigation method impacted green biomass yield (higher with furrow irrigation) but both methods yielded similar dry biomass, while water use was 73% less under drip irrigation. Our findings indicated that the controlled application of water through drip irrigation is able to produce acceptable yields of nutritionally dense fodder species during dry seasons, leading to more effective utilization and resource conservation of available land, fertilizer and water. Higher productivity of these nutritional fodders resulted in higher milk productivity for livestock smallholders. The ability to grow fodder crops year-round in lowland and hill regions of Nepal with limited water storages using low-cost, water-efficient drip irrigation may greatly increase livestock productivity and, hence, the economic security of smallholder farmers.

Assessing Urban Greenhouse Gas Emissions In European Medium And Large Cities: Methodological Considerations, Peter Marcotullio, Andrea Sarzynski, Jochen Albrecht, Niels Schulz, Jake Garcia

Publications and Research

Policymakers need clear, consistent, and reliable information about the location of greenhouse gases and drivers of emitting activity in order to design appropriate mitigating strategies. At the urban scale, there have been challenges in developing consistent and reliable emissions inventories. This chapter examines selected methods to determine greenhouse gas emissions at the urban scale. We describe the various criteria considered when constructing an urban greenhouse gas protocol including the definition of urban, the gasses that are measured, the source they come from, the scope of analysis and how the measurements are undertaken. We then present results for European medium and …

Resistance, Acquiescence Or Incorporation? An Introduction To Land Grabbing And Political Reactions ‘From Below’, Marc Edelman, Ruth Hall, Saturnino M. Borras Jr., Ian Scoones, Ben White, Wendy Wolford

Publications and Research

Political reactions ‘from below’ to global land grabbing have been vastly more varied and complex than is usually assumed. This essay introduces a collection of ground- breaking studies that discuss responses that range from various types of organized and everyday resistance to demands for incorporation or for better terms of incorporation into land deals. Initiatives ‘from below’ in response to land deals have involved local and transnational alliances and the use of legal and extra-legal methods, and have brought victories and defeats. The relevance of political reactions to land grabbing is discussed in light of theories of social movements and …

The Use Of A Statistical Model Of Storm Surge As A Bias Correction For Dynamical Surge Models And Its Applicability Along The U.S. East Coast, Haydee Salmun, Andrea Molod

Publications and Research

The present study extends the applicability of a statistical model for prediction of storm surge originally developed for The Battery, NY in two ways: I. the statistical model is used as a biascorrection for operationally produced dynamical surge forecasts, and II. the statistical model is applied to the region of the east coast of the U.S. susceptible to winter extratropical storms. The statistical prediction is based on a regression relation between the “storm maximum” storm surge and the storm composite significant wave height predicted ata nearby location. The use of the statistical surge prediction as an alternative bias correction for …

Risk Terrain Modeling For Spatial Risk Assessment., Joel M. Caplan, Leslie W. Kennedy, Jeremy D. Barnum, Eric L. Piza

Publications and Research

Spatial factors can influence the seriousness and longevity of crime problems. Risk terrain modeling (RTM) identifies the spatial risks that come from features of a landscape and models how they colocate to create unique behavior settings for crime. The RTM process begins by testing a variety of factors thought to be geographically related to crime incidents. Valid factors are selected and then weighted to produce a final model that basically paints a picture of places where crime is statistically most likely to occur. This article addresses crime as the outcome event, but RTM can be applied to a variety of …

Towards A Theory Of Gis Program Management, Jochen Albrecht

Publications and Research

After a brief flurry of monographs on business and organizational aspects of GIS in the 1990s, little attention has been paid to a systematic approach in support of GIS Program management. Most existing efforts in both public and private enterprises are based on anecdotal evidence. This chapter outlines a range of research questions and the beginning efforts to study modern GIS management practices and help develop a body of knowledge that can be used for the accreditation of GIS Programs and the certification of GIS Program managers.

Female Ghost Or Worker Heroine? – Gender, Space, And Feminist Intervention In Contemporary Taiwan, Anru Lee

Publications and Research

The twenty-five Ladies’ Tomb was the collective burial site of female workers who were drowned during a ferry accident on their way to work at export processing zones in Kaohsiung, Taiwan, in 1973. This essay focuses on the renovation of the tomb in the 2000s, and examines the politics of the feminist movement and the politics of memory as they are expressed through the different meanings bestowed on the deceased women. People involved in the renovation process included the Kaohsiung Association for the Promotion of Women’s Rights (KAPWR), the families of the deceased, and the Kaohsiung City government, all of …

Brooklyn's Thirst, Long Island's Water: Consolidation, Local Control, And The Aquifir, Jeffrey A. Kroessler

Publications and Research

The creation of greater New York City in 1898 promised a solution to the problem of supplying Brooklyn and Queens with water. In the 1850s, the City of Brooklyn tapped ponds and streams on the south side of Queens County, and in the 1880s, dug wells for additional supply. This lowered the water table and caused problems for farmers and oystermen, many of whom sued the city for damages. Ultimately, salt water seeped into some wells from over-pumping. By 1896, Brooklyn’s system had reached its limit. Prevented by the state legislature from tapping the aquifer beneath Suffolk’s Pine Barrens, the …

Self-Reliance Beyond Neoliberalism: Rethinking Autonomy At The Edges Of Empire, Karen Hébert, Diana Mincyte

Publications and Research

Across scholarly and popular accounts, self-reliance is often interpreted as either the embodiment of individual entrepreneurialism, as celebrated by neoliberal designs, or the basis for communitarian localism, increasingly imagined as central to environmental and social sustainability. In both cases, self-reliance is framed as an antidote to the failures of larger state institutions or market economies. This paper offers a different framework for understanding self-reliance by linking insights drawn from agrarian studies to current debates on alternative economies. Through an examination of the social worlds of semisubsistence producers in peripheral zones in the Global North, we show how everyday forms of …

Indicator Analysis For Unpacking Poverty In New York City, Jochen Albrecht, Mimi Abramovitz

Publications and Research

This article presents work that is part of a larger and ongoing research agenda exploring the persistence of health and social problems in some parts of New York City. To this end, the authors have developed a GIS framework that translates a highly diverse set of variables into neighborhood indicators that can help local residents as well as decision makers to understand the relationship between “place” and individual behavior. Using the example of two new indices, Community Loss and Neighborhood Risks, the readers will learn how data can be transformed to emphasize the communal nature of phenomena that is typically …

Le Nature Degli American Studies, Cindi Katz

Publications and Research

Al “Futures of American Studies Institute” di Dartmouth del 2003 lanciai una provocazione sulle “geografie immaginate” dell’americanistica. Volevo mettere in discussione sia le celebrazioni romantiche del “luogo” in quanto elemento in qualche modo autentico e particolare, minacciato da un mondo sempre più globalizzato e controllato dalle multinazionali, sia l’esaltazione della “delocalizzazione” nelle società in rete, negli “spazi di flusso”, nella mobilità senza attrito. Suggerivo che queste, come altre geografie poco studiate, si sposano troppo facilmente con molte correnti dell’eccezionalismo americano.

Remote Sensing Of Soil Moisture In Vineyards Using Airborne And Ground-Based Thermal Inertia Data, Aiman Soliman, Richard J. Heck, Alexander Brenning, Ralph Brown, Stephen Miller

Publications and Research

Thermal remote sensing of soil moisture in vineyards is a challenge. The grass-covered soil, in addition to a standing grape canopy, create complex patterns of heating and cooling and increase the surface temperature variability between vine rows. In this study, we evaluate the strength of relationships between soil moisture, mechanical resistance and thermal inertia calculated from the drop of surface temperature during a clear sky night over a vineyard in the Niagara region. We utilized data from two sensors, an airborne thermal camera (height ≈ 500 m a.g.l.) and a handheld thermal gun (height ≈ 1 m a.g.l.), to explore …

The Role Of Suburbia In The Attribution Of Greenhouse Gas Emissions, Jochen Albrecht, Peter Marcotullio, Andrea Sarzynski, Niels Schulz

Publications and Research

The original goal of the research presented here was to quantify by world region, the contribution of urbanized areas to global greenhouse gas (GHG) emissions (EDGAR, 2011). Regressions on population density and growth rate, GDP, and heating/cooling degree days, as well as a row of other non-significant variables, show that the contribution of urban extents is between 38% and 49% of total emissions (Marcotullio et al., 2012). In spite of using very liberal definitions of urban extents (GRUMP, 2011) this is at the low end of academic estimates (Satterthwaite, 2008; WEO, 2008; Dhakal, 2010). It is no surprise that the …

Global Futures And Government Towns: Phosphates And The Production Of Western Sahara As A Space Of Contention, Mark Drury

Publications and Research

The study of natural resources lends itself to theorizing the politics of nature and the politics of time. The space of Western Sahara, where both remain highly contested, provides an opportunity to consider the ramifications of resources in political conflict at different historical moments. Drawing from environmental histories of North Africa and the Sahara, as well as the anthropology of time, the author focuses on two historical moments. The first, from 1945 to 1972, concerns the discovery of phosphate deposits during the Spanish colonial period and the implications of this discovery for political authority in the Sahara more broadly. The …

Lefsky, Marc Simard, Sassan S. Saatchi, Shihyan Lee, Wenge Ni-Meister, Shilong Piao, Chunxiang Cao, Ramakrishna R. Nemani, Ranga B. Myneni

Publications and Research

The ultimate goal of this multi-article series is to develop a methodology to generate continuous fields of tree height and biomass. The first paper demonstrated the need for Allometric Scaling and Resource Limitation (ASRL) model optimization and its ability to generate spatially continuous fields of tree heights over the continental USA at coarse (1 km) spatial resolution. The objective of this second paper is to provide an assessment of that approach at site scale, specifically at 12 FLUXNET sites where more accurate data are available. Estimates of tree heights from the Geoscience Laser Altimeter System (GLAS) waveform data are used …

The Geography Of Global Urban Greenhouse Gas Emissions: An Exploratory Analysis, Jochen Albrecht, Peter Marcotullio, Amdrea Sarzynski, Niels Schulz, Jake Garcia

Publications and Research

The purpose of this paper is to describe global urban greenhouse gas emissions by region and sector, examine the distribution of emissions through the urban-to-rural gradient, and identify covariates of emission levels for our baseline year, 2000.We usemultiple existing spatial databases to identify urban extent, greenhouse gas emissions (CO2, N2O, CH4 and SF6) and covariates of emissions in a “top-down” analysis. The results indicate that urban activities are significant sources of total greenhouse gas emissions (36.8 and 48.6 % of total). The urban energy sector accounts for between 41.5 and 66.3 % of total energy emissions. Significant differences exist in …

Community Loss: A New Social Indicator, Jochen Albrecht, Mimi Abramovitz

Publications and Research

The Community Loss Index ðCLIÞ, a new social indicator, focuses on the understudied role of place as a source of stress and an aggregator of individual experiences. Building on the relationship between loss and stress, the index attempts to capture collective loss, defined as the chronic exposure by neighborhood residents to multiple resource losses at the same time. Using maps, the article analyzes the spatial distribution of six types of loss in New York City and the characteristics of people who live in high- and low-loss neighborhoods. Regionalization reveals a neighborhood-based concentration of loss, patterns of loss that are both …
