<p class="Abstract"><em>T</em><em>he objective of this study is to evaluate the energy resources (ER) and the regulatory framework of the South American countries aiming at the sustainable development and to develop the South America Energy Integration (SAEI) in the long term focusing on structures such as transmission lines and pipelines. The methodology is based on the IERP (Integrated Energy-Resources Planning) and </em><em>the analysis of the EI existing in South America. As result,</em><em> </em><em>the regulatory assessment provided evidence that the current structure is already in place with binational hydroelectric plants and transnational pipelines that promote energy integration. On the other hand, SAIE still needs an institutional evolution that gives more integration and quicker solutions to international arbitration. Finally, the construction of the attributes and sub-attributes and their respective valuations aiming at a SAEI strategy is not trivial, there is a need for the complete assessment of all the attributes and sub-attributes of the four dimensions established in the IERP methodology of the expansion of the SSERs analyzed to provide a strategy for the SAEI.</em><em></em></p>

Balancing the social, economic and environmental priorities for public health is at the core of the United Nations (UN) approaches to sustainable development, including the Sustainable Development Goals (SDGs). The four dimensions of sustainable diets are often presented as health, society, economics, and the environment. Although sustainable diet research has focused on health and the environment, the social and economic dimensions of sustainable diets and food systems should not be forgotten. Some research priorities and sociocultural indicators for sustainable healthy diets and food systems are outlined in this report. The present goal is to improve integration of the social dimension into research on food and nutrition security.

The Impact

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.

&nbsp; This article discusses the political projects of civilizational level, which are designed and implemented in South America. The author examines MERCOSUR as the largest regional civilizational political project, its sociocultural foundation and institutional superstructure; functionality of the &ldquo;core state&rdquo; in formation and maintenance of the South American civilizational political project; problems of development and future implementation. The article reveals conflict potential of MERCOSUR, as well as sociocultural capabilities for its overcoming by the &ldquo;core state&rdquo; of the project. The research was conducted via application of civilizational-project methodology of interpretation of policy, which is based on methodological synthesis of the principles of project approach with provisions of the theory of civilizations. The author was able to determine the value grounds of MERCOSUR, which comprise its sociocultural foundation; identify the countries competing for status of the &ldquo;core state&rdquo; within the framework of this project. The nature of commonality between the key participants of the projects is identified. Problems and prospect of further development of MERCOSUR civilizational projects are defined. &nbsp;

Abstract. The Community Climate Model (CCM3) from the National Center for Atmospheric Research (NCAR) is used to investigate the effect of the South Atlantic sea surface temperature (SST) anomalies on interannual to decadal variability of South American precipitation. Two ensembles composed of multidecadal simulations forced with monthly SST data from the Hadley Centre for the period 1949 to 2001 are analysed. A statistical treatment based on signal-to-noise ratio and Empirical Orthogonal Functions (EOF) is applied to the ensembles in order to reduce the internal variability among the integrations. The ensemble treatment shows a spatial and temporal dependence of reproducibility. High degree of reproducibility is found in the tropics while the extratropics is apparently less reproducible. Austral autumn (MAM) and spring (SON) precipitation appears to be more reproducible over the South America-South Atlantic region than the summer (DJF) and winter (JJA) rainfall. While the Inter-tropical Convergence Zone (ITCZ) region is dominated by external variance, the South Atlantic Convergence Zone (SACZ) over South America is predominantly determined by internal variance, which makes it a difficult phenomenon to predict. Alternatively, the SACZ over western South Atlantic appears to be more sensitive to the subtropical SST anomalies than over the continent. An attempt is made to separate the atmospheric response forced by the South Atlantic SST anomalies from that associated with the El Niño – Southern Oscillation (ENSO). Results show that both the South Atlantic and Pacific SSTs modulate the intensity and position of the SACZ during DJF. Particularly, the subtropical South Atlantic SSTs are more important than ENSO in determining the position of the SACZ over the southeast Brazilian coast during DJF. On the other hand, the ENSO signal seems to influence the intensity of the SACZ not only in DJF but especially its oceanic branch during MAM. Both local and remote influences, however, are confounded by the large internal variance in the region. During MAM and JJA, the South Atlantic SST anomalies affect the magnitude and the meridional displacement of the ITCZ. In JJA, the ENSO has relatively little influence on the interannual variability of the simulated rainfall. During SON, however, the ENSO seems to counteract the effect of the subtropical South Atlantic SST variations on convection over South America.

The Relationship

The purpose of the study is to examine the longitudinal trajectories of five selected South American countries in the period between 1990 and 2018, applying the Quintuple Helix Innovation Model (QHIM). The aim is to analyse the trends of each country through the relationship of its helices using indicators extracted from an international database in order to establish their articulation and synergies to go in search of sustainable development. Within this dynamic, Venezuela represents the axis country of the study and Argentina, Chile, Colombia, and Peru make up the group that allows the comparison. The research focuses attention on two periods of Venezuelan politics since they allow measuring the variations of the countries under study. The base year is 1996 and is called the pre-Hugo Chávez Frias (HCF) period; the cutoff year for the comparison is 2014 and is called the post-HCF period. The study is longitudinal and descriptive. For the analysis, the five knowledge subsystems (helices) of the QHIM were redefined in order to have precise concepts; a database was designed based on World Bank indicators that were later thematically related to each of the helices. The interrelationships between the helices of each country were also specified in order to determine which were the weakest and which had the most positive or negative influence. In order to calculate the percentage variation of the countries, the Data Envelopment Analysis (DEA) method was applied. In this sense, the most relevant finding is related to the decisions made in the last twenty years from the political helix in Venezuela because it deactivated and disarticulated the others, causing that country to collapse.
