Factors Controlling Pre-Columbian and Early Historic Maize Productivity in the American Southwest,Part 1: The Southern Colorado Plateau and Rio Grande Regions

Maize is the New World’s preeminent grain crop and it provided the economic basis for human culture in many regions within the Americas. To flourish, maize needs water, sunlight (heat), and nutrients (e.g., nitrogen). In this paper, climate and soil chemistry data are used to evaluate the potential for dryland (rain-on-field) agriculture in the semiarid southeastern Colorado Plateau and Rio Grande regions. Processes that impact maize agriculture such as nitrogen mineralization, infiltration of precipitation, bare soil evaporation, and transpiration are discussed and evaluated. Most of the study area, excepting high-elevation regions, receives sufficient solar radiation to grow maize. The salinities of subsurface soils in the central San Juan Basin are very high and their nitrogen concentrations are very low. In addition, soils of the central San Juan Basin are characterized by pH values that exceed 8.0, which limit the availability of both nitrogen and phosphorous. In general, the San Juan Basin, including Chaco Canyon, is the least promising part of the study area in terms of dryland farming. Calculations of field life, using values of organic nitrogen for the upper 50 cm of soil in the study area, indicate that most of the study area could not support a 10-bushel/acre crop of maize. The concepts, methods, and calculations used to quantify maize productivity in this study are applicable to maize cultivation in other environmental settings across the Americas.     

10,000 years of human predation and size changes in the owl limpet (Lottia gigantea) on San Miguel Island,California

To investigate potential human impacts on California Channel Island shellfish stocks over the past 10,000 years, we measured 1718 owl limpet shells from 19 archaeological components on San Miguel Island. Inhabiting the middle intertidal zone of Pacific Coast rocky shores, owl limpets are slow-growing mollusks that can live for 30 years and reach lengths of over 100 mm. Recent ecological studies indicate that owl limpets are highly susceptible to heavy human predation, which results in reduced mean shell sizes among Lottia populations along the coasts of Alta and Baja California. On San Miguel Island, we identified a significant trans-Holocene reduction in mean owl limpet size, beginning more than 6500 years ago and accelerating at least 4400 years ago. Fluctuations in limpet size show no clear correlation with changes in sea surface temperature and marine productivity, suggesting that increased predation by growing human populations was primarily responsible for the reduction in Lottia size over time. Our results provide further evidence that prehistoric peoples significantly influenced nearshore fisheries long before the development of the commercial and industrialized fisheries of historic times.     

Anomalies in Red and Blue II: Towards an understanding of the roles of setting, values, and demography in the 2004 and 2008 U.S. presidential elections

Counties identified as anomalous in the 2004 US presidential election - large metropolitan counties and majority-minority counties that voted Republican and non and small-metropolitan counties that voted Democratic, are the subject of a qualitative analysis to assess why they were exceptions to the conventional wisdom of a Red and Blue America polarized along metropolitan-non-metropolitan and modern versus traditional dimensions. Contacts with professional colleagues, and with media and partisan representatives, and visits to selected counties provided valuable insights and helped us to assess the extent to which the county votes in 2008 reinforced or changed the broad Red and Blue dimensions derived from 2000 to 2004.     

Sex,drink, and state anxieties: governance through the gay bar

Gay bars have been central to the social and cultural geography of queer folk throughout the twentieth century. In North America, Liquor Control Boards have been important in governing homosexuality. In order to explore the spatial governance of homosexuals, this paper uses a Foucauldian governmentality perspective to analyze data from Washington State Liquor Control Board (WSLCB) enforcement and hearing files between 1934 and 1971. While the WSLCB governed heteronormatively, it did so with a relatively light touch through the deployment and selective enforcement of often vague administrative rules. Adherence to the rules, meanwhile, relied upon an ability and willingness to understand authorities’ intentions and imaginations and to self-govern accordingly. Gay bars were somewhat privileged vis-à-vis neighboring straight bars, due to the unintended consequences of certain state practices, a desire by state authorities to closet homosexuality generally, and a propensity for self-governance on the parts of gay bar owners, managers, and patrons. Our findings add nuance to work on Foucauldian studies in geography, work on licensing and regulation, and urban gay histories.     

The new water architecture in southern Africa: reflections on current trends in the light of 'Rio+10'

UN Secretary–General Kofi Annan has identified water and sanitation as a principle area of focus for the forthcoming World Summit on Sustainable Development (WSSD). It is fitting that this meeting is being held in Johannesburg, as water resources management issues are of primary importance to the southern African region. There is a new water architecture being developed in the region, one that hopes to correct abiding structural inequalities of access between and among states, communities and peoples. Part of this new water architecture includes an enhanced role for the private sector and 'the market' in the provision and management of this crucial resource. This is a role that many feel will exacerbate rather than alleviate historically derived problems of underdevelopment. It is a role, therefore, that may undermine many of the positive developments that have taken place in the region over time. If regional leaders are interested in sustainable and equitable water resources management, they must be prepared openly to debate this issue with all interested parties not only at the WSSD, but also in the region and beyond.
