An Empirical Enquiry into the Impact of Urban Planning Policy on Urban Growth

Recent research has stressed the need to evaluate the economic implications of urban planning policy. In this article, we present empirical evidence on the impact of this policy on the population growth of towns and cities. A simple theoretical model serves to highlight the mechanisms whereby this policy may affect urban growth. The model yields a reduced-form equation which we estimate for the towns and cities of Andalusia (Spain). The empirical model strongly supports the claim that urban planning policy considerably affects urban growth and thus, the distribution of population across space. Our results suggest that urban planning policy is contributing to the reduction of diseconomies of agglomeration in larger cities. On the negative side, we find that urban plans are subject to obsolescence, which slows down growth.     

An Index of Social and Economic Development in the Community's Objective-1 Regions of Countries in Southern Europe

In this article we calculate an indicator of social and economic development using the DP₂ distance method to measure the disparities in Objective-1 regions of southern European countries for 2006. In addition to per capita income, socio-economic components such as health, education, employment, scientific and technological development and infrastructure provision have been incorporated into the index. We examine the issue of whether the Europe Union regions included in the Convergence Objective achieved a lower level of development than the regions no longer covered in this objective for the 2007–2013 programming period by establishing a territorial classification based on the value yielded by the variables of the DP₂. Our indicator constitutes a novel contribution insofar as it was constructed using a large number of variables. In essence, we show that not all the regions of the Convergence Objective presented a lower level of economic and social development than those that lost this consideration between 2007 and 2013 and the opposite.     

Who cares in Nicaragua? A care regime in an exclusionary social policy context

In Latin American countries with historically strong social policy regimes (such as those in the Southern Cone), neoliberal policies are usually blamed for the increased burden of female unpaid work. However, studying the Nicaraguan care regime in two clearly defined periods — the Sandinista and the neoliberal eras — suggests that this argument may not hold in the case of countries with highly familialist social policy regimes. Despite major economic, political and policy shifts, the role of female unpaid work, both within the family and in the community, remains persistent and pivotal, and was significant long before the onset of neoliberal policies. Nicaragua's care regime has been highly dependent on the ‘community’ or ‘voluntary’ work of mostly women. This has also been, and continues to be, vital for the viability of many public social programmes.     

The Role of Future Discounting in Subsistence Decisions: The Case of Hohokam Agave Bajada Cultivation

This article demonstrates the relevance of future discounting behavior to studies of prehistoric subsistence strategies. The case study of Agave spp. bajada cultivation among the Classic Period, a.d. 1150–1450, Hohokam of southern Arizona illustrates how slight discounting of future rewards can significantly alter agriculture investment strategies. Despite a higher kcal/hour return than maize agriculture, agave cultivation lessened or ceased in several communities during a time in which intensification would be predicted due to inferred subsistence stress. We surmise the decade-long maturation of agave made it unattractive relative to more immediate return resources in any context that presented risks to land tenure. The cessation of agave cultivation can be understood on two levels of explanation. The long-term investments required by agave and tendency to discount future rewards are the ultimate causes. Political and social instability during the tumultuous Classic period, causing increased insecurity in land tenure, are the proximal causes.     

Railways as a Factor of Change in the Distribution of Population in Spain, 1900–1970

Abstract

The central focus of this work is to test a new methodology to measure the impact of the railway on the distribution of population, in this case in Spain. To achieve this, it was necessary to previously integrate data relating to population and railway lines into a geographical information system. The result was a spatial database that includes population data from homogeneous census series obtained for the municipal scale and the evolution of the railway network in service at corresponding points in time. This allowed the authors to apply spatial-temporal analysis. By so doing, this work constitutes an analysis of a new methodology, as they used exploratory spatial data analysis and geographically weighted regression to detect spatial patterns and estimate the influence of the railway and distance from the coast on population change. The results obtained show that the influence of the railway was very pronounced in some areas, while in others it was just one of the factors that could explain major changes in population distribution.     

Evolution of the Territorial Coverage of the Railway Network and its Influence on Population Growth: The Case of England and Wales, 1871–1931

Abstract

The introduction of the railway network brought with it an unprecedented improvement in accessibility. In this work, the authors analyze the evolution of the territorial coverage of the railway network and its influence on the uneven distribution of population. To carry out this research, they used comparable data on total population obtained from census records relating to civil parishes of England and Wales, taken at 10-year intervals from 1871. The hypothesis that they wished to test was that good access to a railway station was related to significant increases in population. This exercise provides a better understanding of regional variations in population growth and allows the authors to identify current differences between urban and rural areas that have resulted from their historical evolution.     

The southernmost records of Anhingidae and a new basal species of Anatidae (Aves) from the lower–middle Miocene of Patagonia,Argentina

New bird fossils from the Santa Cruz Formation (lower–middle Miocene), Santa Cruz Province, Patagonia, Argentina, are described. They represent an indeterminate species of the extinct anhingid Macranhinga and a new genus and species of basal Anatidae Ankonetta larriestrai. The record of the giant darter Macranhinga constitutes the southernmost record for the family, and expands the known stratigraphic range of the genus, previously restricted to the upper Miocene. Based on an analysis of the fossil anhingid record from South America, we hypothesize that giant darters disappeared from South America in the early Pliocene due to climatic deterioration, regression of marine and freshwater environments, the arrival of placental carnivorous mammals, and also probably by competition with phalacrocoracid cormorants. The new anatid Ankonetta is based on an incomplete but informative tarsometatarsus, with superficial similarities to extant Dendrocygna. A brief overview of several fossil ducks from the Patagonian Cenozoic concludes that most pre-Pliocene examples belong to non-anatine taxa, indicating that plesiomorphic ducks were the dominant anseriforms in those times, a pattern also evident on other continents.
