Debris flow susceptibility mapping at a regional scale along the National Road N7, Argentina

A first assessment of debris flow susceptibility at a large scale was performed along the National Road N7, Argentina. Numerous catchments are prone to debris flows and likely to endanger the road-users. A 1:50,000 susceptibility map was created. The use of a DEM (grid 30 m) associated to three complementary criteria (slope, contributing area, curvature) allowed the identification of potential source areas. The debris flow spreading was estimated using a process- and GISbased model (Flow-R) based on basic probabilistic and energy calculations. The best-fit values for the coefficient of friction and the mass-to-drag ratio of the PCM model were found to be ? = 0.02 and M/D = 180 and the resulting propagation on one of the calibration site was validated using the Coulomb friction model. The results are realistic and will be useful to determine which areas need to be prioritized for detailed studies.

Plan de Gestión de la red de senderos ecoturísticos de la Sierra de San Javier, Tucumán- Argentina

El “Parque Sierra de San Javier” és un espai natural al costat d’ un gran nucli urbà, San Miguel de Tucumán (Argentina). A la Sierra es troba la comuna de San Javier, on s’ ha creat el CIC (Centre Integrador Comunitari). És a partir del CIC que s’ elabora un pla integral que inclou el projecte d’ ecoturisme. Aquest projecte es basa en una gestió de la xarxa de camins existents a la Sierra. Es fa un inventari de cadascun dels camins de la xarxa i s’ analitza cadascun d’ ells amb uns índexs de potencial paisatgístic i interpretatiu i es valora també la seva conservació. A partir d’ aquests valors es planteja un pla d’ actuació de recuperació i manteniment, i un pla d’ actuació turística en el que es millora l’ estat del camí; s’ intal•len panells informatius i senyalització. El projecte conté les fitxes d’ informació de cadascun dels itineraris amb un mapa i amb d’ altres informacions d’ interès pels usuaris dels senders

An analysis of the metabolic patterns of two rural communities affected by soy expansion in the North of Argentina

The soy expansion model in Argentina generates structural changes in traditional lifestyles that can be associated with different biophysical and socioeconomic impacts. To explore this issue, we apply an innovative method for integrated assessment - the Multi Scale Integrated Analysis of Societal and Ecosystem Metabolism (MuSIASEM) framework - to characterize two communities in the Chaco Region, Province of Formosa, North of Argentina. These communities have recently experienced the expansion of soy production, altering their economic activity, energy consumption patterns, land use, and human time allocation. The integrated characterization presented in the paper illustrates the differences (biophysical, socioeconomic, and historical) between the two communities that can be associated with different responses. The analysis of the factors behind these differences has important policy implications for the sustainable development of local communities in the area.

The Impact of Trade on Technology and Skill Upgrading Evidence from Argentina

In the last 20 years, wage inequality has increased in many developing countries. Most research on this topic focuses on two alternative causes: trade or skill-biased technical change. Several empirical studies in both developed and developing countries document increases in skill intensity within all sectors, favoring the technological change explanation over trade. Instead, I present and test a model where bilateral trade liberalization increases exporting revenues inducing more firms to enter the export market and to adopt skilled-biased new technologies. I find that the increase in the relative demand of skilled labor does not come from labor reallocation across sectors or firms but from skill upgrading within firms. Firms that upgrade technology faster also upgrade skill faster. Finally, firms entering the export market after liberalization become more skill and technology-intensive than non exporters.

Global Prospects for Dairy in Argentina and Chile: Evidence from Field Visits and Model Simulations, August 2006

We assess the international competitiveness of the dairy industries in Argentina and Chile, combining recent market intelligence gathered from field visits with quantitative simulations of global policy reform scenarios. Both countries exhibit strong potential for export growth but face significant internal and external barriers to expanding their dairy industries. Global policy reforms would resolve some of the international obstacles to their expansion. Argentina has great potential, but it is handicapped by its current macroeconomic policies, trade policy distortions, and the uncertainty associated with policy implementation. Chile is more limited in terms of natural capacity for expansion, but it has a positive trade and investment environment.

Efetividade no diagnóstico da tuberculose em Foz do Iguaçu, tríplice fronteira Brasil, Paraguai e Argentina

Objetivou-se avaliar a efetividade dos serviços de saúde no diagnóstico da tuberculose em Foz do Iguaçu-PR. Realizou-se uma pesquisa avaliativa, com desenho epidemiológico transversal. Foram entrevistados 101 doentes de tuberculose em 2009, utilizando um instrumento baseado no Primary Care Assessment Tool . A análise ocorreu a partir de proporções e respectivos intervalos de confiança (95%) e mediana. O Pronto Atendimento (37%) e a Atenção Básica à Saúde (ABS) (36%) foram os locais mais buscados. O acesso à consulta no mesmo dia alcançou 70%, mas a suspeição da doença foi menor que 47%; a baciloscopia realizada em 50% dos doentes. Concluiu-se que apesar desses serviços atenderem rapidamente, isso não determinou alcance do diagnóstico, levando o doente a procurar os serviços especializados, mais efetivos na descoberta dos casos. A busca pela ABS gerou maior tempo e maior número de retornos para o diagnóstico da tuberculose na tríplice fronteira.
