To anyone who has made a careful study of aeronautics and its possibilities in the commercial world it is evident that South America offers unusual opportunities for development by aircraft, and of all South American countries Peru, on account of its climate, its rich natural resources, its geographical position and its peculiar topographical configairation, is almost ideal. To fully appreciate the significance of this remark it is necessary to have a very clear conception of all those factors which go to make aerial transport a commercial possibility.

Para que uma inserção internacional soberana de uma nação seja viável, deve-se necessariamente dispor de autonomia elevada para decidir acerca de suas políticas internas e externas. No que tange aos recursos naturais sul-americanos, a competição internacional pelas reservas, produção e renda está subordinada às geoestratégias dos Estados hegemônicos, que privilegiam a manutenção da ordem internacional em detrimento da defesa de interesses específicos dos Estados da América do Sul. Neste contexto, o presente artigo busca sistematizar uma estratégia de política externa no qual o uso e proveito dos recursos naturais sul-americanos seja endógeno, realizando uma análise dos principais recursos naturais da região e, simultaneamente, propondo a discussão acerca de uma política externa que abranja a soberania e autonomia dos recursos naturais. Palavras-chave: política externa, recursos naturais, América do Sul, soberania, integração regional.     Abstract: In a competitive and hierarchical international environment, the autonomy in the foreign policy of the States is indispensable for the decision of its internal and external policies. With respect to the South American natural resources, the international competition for reserves, production and income of these funds is subject to geostrategies of hegemonic states, which privilege the maintenance of its status quo in the international system over the defense of specific South America States' interests. In this context, it is essential to formulate a foreign policy strategy in which the use and advantage of South American natural resources is endogenous. By this context, this article aims to conduct an analysis of the main natural resources of the region and, at the same time, proposing the discussion of a foreign policy that covers the sovereignty and autonomy of natural resources. Keywords: foreign policy, natural resources, South America, sovereignty, regional integration.     Recebido em: outubro/2016; Aprovado em: abril/2017.

In a context of accelerated climate change, increasing scarcity, and global population growth, environmentalissues and natural resources have become a matter of heightened concern for international security.Competition for access to and use of scarce natural resources are increasingly part of the nations’ geostrategicpolicies. South America, one of the richest regions in the world in terms of natural resources, especiallywater, attracts the international interest. This article builds up a picture of such water resources and presentsevidence suggesting the urgent need for more effective cooperation among South American states to establishguidelines for the management and defense of the region’s natural wealth.

A questão ambiental e dos recursos naturais, pela mudança climática em curso, crescente escassez e aumento populacional global, se tornou motivo de preocupação e de segurança internacional. A América do Sul se insere nesse contexto devido à sua riqueza natural e hídrica, o que desperta interesse internacional e torna latente a necessidade de marcos regulatórios para essas questões. O presente artigo tem como objetivo traçar um panorama dos recursos naturais sul-americanos, especialmente da água, buscando não apenas ressaltar como esse tema ganha espaço no cenário internacional e no âmbito da segurança, mas evidenciando a necessidade premente de ações compartilhadas entre os Estados sul-americanos na construção de diretrizes para o manejo e defesa dessa riqueza natural da região, algo que envolve inclusive interesses globais. ABSTRACTThe environmental and natural resources issues, because of the ongoing climate change, the growing scarcity, and the global population growth have become a cause of concern and international security. South America is inserted in this context due to its natural and water richness, which attracts international interest and makes latent the need for regulatory frameworks in this area. The objective of this article is draw a scenery of the South American natural resources, especially water, not only to highlight how this issue gains space in the international scene and in the area of international security, but highlighting the urgent need of shared actions among the southern americans states on the construction of guidelines for the management and the defense of this natural wealth of the region, something that involves global interests.Palavras-Chave: Recursos Naturais; América do Sul; Recursos Hídricos; Segurança Internacional; Meio AmbienteKeywords: Natural Resources; South America; Water Resources; International Security; Environment Recebido em 30 de Janeiro de 2018 | Aceito em 24 de março de 2018.Received on January 30, 2018 | Accepted on March 24, 2018.

The Pampean Region contains sedimentary sequences with abundant mammal fossil records, which constitute the chronological outline of the Plio–Pleistocene of South America. These classic localities have been used for more than a century to correlate with other South American regions. Throughout this time, a series of misinterpretations have appeared. To understand the stratigraphic significance of these localities and the geochronological situation of each unit referring to the Pleistocene, a critical historical study of the antecedents was carried out, evaluating the state of each unit. The biostratigraphic studies of the Pampean Region’s mammalian faunas improved the understanding of biogeographic changes taking into account the environmental fluctuations of the Pleistocene.

Equine influenza virus (EIV) is one of the most important respiratory pathogens of horses as outbreaks of the disease lead to significant economic losses worldwide. In this review, we summarize the information available on equine influenza (EI) in South America. In the region, the major events of EI occurred almost in the same period in the different countries, and the EIV isolated showed high genetic identity at the hemagglutinin gene level. It is highly likely that the continuous movement of horses, some of them subclinically infected, among South American countries, facilitated the spread of the virus. Although EI vaccination is mandatory for mobile or congregates equine populations in the region, EI outbreaks continuously threaten the equine industry. Vaccine breakdown could be related to the fact that many of the commercial vaccines available in the region contain out-of-date EIV strains, and some of them even lack reliable information about immunogenicity and efficacy. This review highlights the importance of disease surveillance and reinforces the need to harmonize quarantine and biosecurity protocols, and encourage vaccine manufacturer companies to carry out quality control procedures and update the EIV strains in their products.

Abstract. The geomagnetic field in the Brazilian sector is influenced by the South American Magnetic Anomaly (SAMA) that causes a decrease in the magnitude of the local geomagnetic field when compared to other regions in the world. Thus, the magnetometer network and data set of space weather over Brazil led by Embrace are important tools for promoting the understanding of geomagnetic fields over Brazil. In this sense, in this work we used the H component of geomagnetic fields obtained at different sites in South America in order to compare results from the phase coherence obtained from wavelet transform (WT). Results from comparison between Cachoeira Paulista (CXP) and Eusébio (EUS), and Cachoeira Paulista and São Luis (SLZ), indicated that there exist some phenomena that occur simultaneously in both locations, putting them in the same phase coherence. However, there are other phenomena putting both locations in a strong phase difference as observed between CXP and Rio Grande, Argentina (RGA). This study was done for a specific moderate geomagnetic storm that occurred in March 2003. The results are explained in terms of nonlinear interaction between physical phenomena acting in distinct geographic locations and at different times and scales. Keywords. Geomagnetism and paleomagnetism (time variations – diurnal to secular)

The occasion of honouring the memory of John Brooks, a great friend of Latin America, has helped me vanquish my initial reluctance to tackle a topic that is as broad, varied and still open-ended as the present situation of democracy in South America. As a first measure of my limitations, with the exception of some references to Costa Rica and Mexico, I will not discuss Central America and the Caribbean, not because I feel these regions are unimportant but because, simply, I do not know enough about them. However, when I feel that I am on sufficiently solid ground so as to refer to Latin America as a whole, I will do so.I begin by noting that in contemporary South America some countries satisfy the definition of political democracy. Those countries share two main characteristics. One is that they hold elections under universal adult franchise that, at least at the national level, are reasonably fair and competitive. These are standard criteria in the political science literature. However, having in mind the experience of Latin America and elsewhere in the third world, I believe that we should add that such elections must be institutionalised. By this I mean that all relevant actors expect that elections of this kind will continue being held in the indefinite future so, whether they like or not, it is rational for them to play democracy, not coup-making or insurrection. We should also stipulate that these elections are decisive, in the sense that those who are elected do occupy the respective offices and end their terms in the constitutionally prescribed way; they are not, as it has happened too often in Latin America, prevented from occupying office or thrown out of it because some supra-constitutional power feels that they are the ‘wrong people’.The second characteristic is the enjoyment of certain political rights, especially of opinion, expression, association, movement and access to a reasonably free and pluralist media. Of course, these and other rights are important per se; in addition, they are instrumental – necessary conditions – for the effectuation of the kind of elections I have just specified.

The name Salicornia cuscoensis given to a plant from high Andean saltmarshes near Cusco [Cuzco] and Ayacucho, Peru (South America) is validated by a diagnosis and description. The main morphological characters that separate S. cuscoensis from other closely related species are creeping habit, delicate branches, inflorescence of short and thin spikes, and seed indumentum. The new species clearly differs from other perennial Salicornia taxa growing in high Andean saltmarshes such as S. pulvinata and S. andina. The former forms small compact cushions producing very short, few-flowered inflorescences. The latter shows woody stems and forms larger rounded carpets. Morphologically, S. cuscoensis is also similar to S. magellanica, a species growing along the seashore in southern Patagonia and Tierra del Fuego, but the latter has shorter and wider inflorescences and larger seeds with a different type and arrangement of indumentum. Molecular analyses also supported the separation of S. cuscoensis. Data on habitat, distribution and phylogenetic relationships are presented for the new species and its relatives, and an identification key is given for the South American taxa of the genus Salicornia.

During the warm season 2002-2003, the South American Low-Level Jet Experiment (SALLJEX) was carried out in southeastern South America. Taking advantage of the unique database collected in the region, a set of analyses is generated for the SALLJEX period assimilating all available data. The spatial and temporal resolution of this new set of analyses is higher than that of analyses available up to present for southeastern South America. The aim of this paper is to determine the impact of assimilating data into initial fields on mesoscale forecasts in the region, using the Brazilian Regional Atmospheric Modeling System (BRAMS) with particular emphasis on the South American Low-Level Jet (SALLJ) structure and on rainfall forecasts. For most variables, using analyses with data assimilated as initial fields has positive effects on short term forecast. Such effect is greater in wind variables, but not significant in forecasts longer than 24 hours. In particular, data assimilation does not improve forecasts of 24-hour accumulated rainfall, but it has slight positive effects on accumulated rainfall between 6 and 12 forecast hours. As the main focus is on the representation of the SALLJ, the effect of data assimilation in its forecast was explored. Results show that SALLJ is fairly predictable however assimilating additional observation data has small impact on the forecast of SALLJ timing and intensity. The strength of the SALLJ is underestimated independently of data assimilation. However, Root mean square error (RMSE) and BIAS values reveal the positive effect of data assimilation up to 18-hours forecasts with a greater impact near higher topography.
