Aborda, por um lado, a relação entre a economia local no Município de Oriximiná - PA e sua inserção no Comércio Internacional do minério de alumínio. E, por outro, os mecanismos de interação e alianças entre os atores locais público e privado com o setor minerador de alumínio, representado pela Companhia MRN, vis à vis a consecução de um projeto de desenvolvimento local em bases endógenas. O estudo busca compreender como a interação entre interesses públicos/privados, coletivos/individuais, orgânicos/corporativos em âmbito local influenciam no desenvolvimento endógeno do Município. Não obstante, avaliar a dimensão das restrições estruturais, condicionadas pela dinâmica das relações comerciais no setor mundial do minério de Alumínio, aos processos internos de articulação para o desenvolvimento local. O Problema proposto está em compreender como as oportunidades e restrição da explotação de uma mina world class impulsiona processos de desenvolvimento local. Partindo-se da Nova Teoria Econômica aliada à Teoria do Comércio Internacional e Geografia Econômica, buscou-se delinear os parâmetros de inserção da economia mineradora do alumínio local no cenário internacional e suas inter-relações resultantes, sejam estas sob o aspecto tecnológico ou mercadológico. Numa perspectiva local, procurou-se identificar os processos interativos e seu grau de convergência entre Setor Público (via Plano Diretor Municipal) com vistas à concretização de um projeto de desenvolvimento endógeno mediado pela formação de alianças (Clusters) que atendessem às suas respectivas exigências tecnológica, econômica e institucional. Para tanto, o trabalho recorreu às Teorias do Crescimento e Desenvolvimento econômico e dos Sistemas para explicitar os mecanismos que regem as interações entre os atores locais e, em última análise, determinam suas ações sociais no processo de desenvolvimento endógeno. O método adotado é o hipotético-dedutivo utilizando-se instrumentos de coleta de dados secundários e primários. Através de um processo de modelagem computacional e, recorrendo aos Relatórios Fiscais da Prefeitura de Oriximiná e Contábeis da Mineração Rio do Norte buscou-se o aprofundamento sobre a natureza e aplicação dos recursos gerenciados por ambas Instituições. Desenvolve-se ainda, um modelo representativo da dinâmica do desenvolvimento endógeno local tendo o PIB Municipal per capita como proxy através do método de análise multivariada utilizando a técnica da regressão linear múltipla. Desenvolve-se também uma análise da autocorrelação da economia de Oriximiná com o seu entorno a partir da técnica de processamento de dados espaciais geograficamente referenciados bem como a técnica de acessibilidade locacional de Oriximiná. A apresentação dos resultados utiliza modelos simbólicos, tabelas e gráficos diversos. A conclusão é de que a atividade minerária encontra-se descolada do processo de crescimento local por não produzir spillover e por não internalizar o grosso da sua renda no Município dada sua estratégia competitiva. Contudo, a dinâmica local também sofre restrições por conta de sua localização espacial à margem do eixo econômico Regional e pela baixa capacidade empreenditiva e articulatória demonstrada pela administração pública local.

The concept of region raises two related historical problems. First of all, it concerns the epistemological accomplishment of regional history, since the need to provide a total history, one of the main challenges of the Annales movement, undergoes an impact with the notion of local, so that the overflight of the historic totality becomes nowadays an intensive totality. The historian who overflies the reality is replaced by the wanderer historian. In addition to this epistemological question, we can think about the historical feature of spaces. From an ontological point of view, according to the modes of its composition, as well as from the standpoint of its practical constitution, space can be either smooth or striated. These types of space belong to the Gilles Deleuze s nomadology and their definition might improve the characterization and description of historical spaces with regard to a certain contemporary historiographical movement known as the New Cultural History.Key Words: history;space;nomadism.

Based on the candidature of a region in the Swiss Alps as a World Natural Heritage Site (WHS), this article outlines the negotiation process as reflected in the local media. Discussions of the World Heritage issue over a time span of 4 years revealed how the region concerned was discursively constructed and that discursive constructions implied specific views of nature. By elaborating on these conflicting views of nature, we intend to reflect on the implicit meanings that influenced and structured the debate about the WHS and more generally the issues of sustainable regional development. The results show a broadening of the debate from a rather fragmented toward a more inclusive view of nature, which relates to basic assumptions of the global discourse on sustainable development. Additionally, a view of nature as inherited from past generations extended the WHS discussion and thus gave a new dimension to the concept of sustainability.
Market Prices and Food Aid Local and Regional Procurement and Distribution: A Multi-Country Analysis
Resumo:
To date, no research has rigorously addressed the concern that local and regional procurement (LRP) of food aid could affect food prices and food price volatility in food aid source and recipient countries. We assemble spatially and temporally disaggregated data and estimate the relationship between food prices and their volatility and local food aid procurement and distribution across seven countries for several commodities. In most cases, LRP activities have no statistically significant relationship with either local price levels or food price volatility. The few exceptions underscore the importance of market monitoring. (C) 2013 Elsevier Ltd. All rights reserved.

Local and regional procurement (LRP) of food aid is often claimed to lead to quicker and more cost-effective response. We generate timeliness and cost-effectiveness estimates by comparing US-funded LRP activities in nine countries against in-kind, transoceanic food aid shipments from the US to the same countries during the same timeframe. Procuring food locally or distributing cash or vouchers results in a time savings of nearly 14 weeks, a 62 percent gain. Cost-effectiveness varies significantly by commodity type. Procuring grains locally saved over 50 percent, on average, while local procurement of processed commodities was not always cost-effective. (C) 2013 Elsevier Ltd. All rights reserved.

We compare the impacts across a range of criteria of local and regional procurement (LRP) relative to transoceanic shipment of food aid in Burkina Faso and Guatemala. We find that neither instrument dominates the other across all criteria in either country, although LRP commonly performs at least as well as transoceanic shipment with respect to timeliness, cost, market price impacts, satisfying recipients' preferences, food quality and safety, and in benefiting smallholder suppliers. LRP is plainly a valuable food assistance tool, but its advantages and disadvantages must be carefully weighed, compared, and prioritized depending on the context and program objectives.

Region-specific empirically based ground-truth (EBGT) criteria used to estimate the epicentral-location accuracy of seismic events have been developed for the Main Ethiopian Rift and the Tibetan plateau. Explosions recorded during the Ethiopia-Afar Geoscientific Lithospheric Experiment (EAGLE), the International Deep Profiling of Tibet, and the Himalaya (INDEPTH III) experiment provided the necessary GT0 reference events. In each case, the local crustal structure is well known and handpicked arrival times were available, facilitating the establishment of the location accuracy criteria through the stochastic forward modeling of arrival times for epicentral locations. In the vicinity of the Main Ethiopian Rift, a seismic event is required to be recorded on at least 8 stations within the local Pg/Pn crossover distance and to yield a network-quality metric of less than 0.43 in order to be classified as EBGT5(95%) (GT5 with 95% confidence). These criteria were subsequently used to identify 10 new GT5 events with magnitudes greater than 2.1 recorded on the Ethiopian Broadband Seismic Experiment (EBSE) network and 24 events with magnitudes greater than 2.4 recorded on the EAGLE broadband network. The criteria for the Tibetan plateau are similar to the Ethiopia criteria, yet slightly less restrictive as the network-quality metric needs to be less than 0.45. Twenty-seven seismic events with magnitudes greater than 2.5 recorded on the INDEPTH III network were identified as GT5 based on the derived criteria. When considered in conjunction with criteria developed previously for the Kaapvaal craton in southern Africa, it is apparent that increasing restrictions on the network-quality metric mirror increases in the complexity of geologic structure from craton to plateau to rift.

Groundwater pumping from aquifers in hydraulic connection with nearby streams is known to cause adverse impacts by decreasing flows to levels below those necessary to maintain aquatic ecosystems. The recent passage of the Great Lakes--St. Lawrence River Basin Water Resources Compact has brought attention to this issue in the Great Lakes region. In particular, the legislation requires the Great Lakes states to enact measures for limiting water withdrawals that can cause adverse ecosystem impacts. This study explores how both hydrogeologic and environmental flow limitations constrain groundwater availability in the Great Lakes Basin. A methodology for calculating maximum allowable pumping rates is presented. Groundwater availability across the basin is shown to be constrained by a combination of hydrogeologic yield and environmental flow limitations varying over both local and regional scales. The results are sensitive to factors such as pumping time and streamflow depletion limits as well as streambed conductance. Understanding how these restrictions constrain groundwater usage and which hydrogeologic characteristics and spatial variables have the most influence on potential streamflow depletions has important water resources policy and management implications.
