The systematic installation of agricultural colonies based on European immigrants in Santa Fe province during the second half of the nineteenth century paved the way for the consolidation of an extensive rainfed agriculture over the fertile Argentine pampas. In this process a group of German land entrepreneurs played a crucial role. This paper aims to make new contributions to the analysis of these actors by working on two case studies, which represent different moments of the evolution of the colonization process. We use deeds of sales and private accounts to study the different logics of action in the market, the variation of profit rates, risks levels and business viability. [ABSTRACT FROM AUTHOR]

The paper addresses vulnerability to Global Environmental Change of rural producers of Mendoza River basin, in Argentina. Vulnerability is a complex phenomenon that is generated at the intersection of environmental, social and economic dimensions. From a qualitative study based on in-depth interviews with producers of the study area, the paper explain the processes affecting actors (exposures / sensitivities) and the practices (adaptations) they develop to address these phenomena. The main idea is that hydroclimatological events act on a number of previous, long-term vulnerabilities defined by access to resources. Also it shows that resources are critical to the development of adaptive capacities, but finds that "availability of resources" and "capacity building" are not phenomena always related by a linear and direct causality. That is, sometimes the mere existence of resources is not enough to foster adaptive capacities. Noting some capacities gaps, the article identifies critical factors that could improve rural actors' capacities and could strengthen them to cope with future global climate events and other factors that affect their living conditions.

During the neoliberal period, the State reconfigured its way of acting in diverse spaces of the society. In that context, the enactment of the Decreto de Desregulación Económica 2284 de 1991 had a deep impact in the Argentinian rural sector. Because of that, we analyze the problematization process of the issue by different agents; the position took by the State materialized in the text of the Decree; and some reactions that it aroused, based in the classic contributions of Oszlak and O'Donnell. In this manner, we deepen our understanding of the strategies and forms of communication that are articulated in the process of adopting a public policy. In methodological terms, we reviewed the content of some discourses published in specialized newspapers between 1990 and 1991 and we apply discourse analysis techniques on the original Decree and two company's advertising. This paper concludes that even when a favorable position about agrarian deregulation had consensus between hegemonic agents, the intensity of the public policy transcended its expectations, empowering profound economic, social and political transformations.

The purpose of this paper is to study the activities of rural extension conducted between 1973 and 1983 by one of the main Argentinean state agencies: the National Agricultural Technology Institute (INTA). Regarding this period, which starts and ends with a democratic transition, an analysis has been made on the content and perspective of the organization's rural extension agenda in relation to the transformations seen in matters of sectoral policies, socioeconomic changes in the rural area, and in the implementation of repressive mechanisms. There has been an evaluation on the operation of INTA's state bureaucracy throughout its processes of institutional reconfiguration: one in 1973 alongside that year's democratic transition and the other in 1976 in hand with Argentina's last dictatorship. In light of documentary sources and interviews, a review has been drafted on institutional directives, nationwide coordination of agricultural policies, and the experiences of the INTA extension workers, primarily located in the Buenos Aires province. Additionally, we have identified the existence of various practices during the previous years of the last dictatorship involving direct contact with rural populations different from those of a more traditional approach, and its limitations have also been highlighted. Finally, we have analyzed the reorientation of the institution rural extension tasks as it underwent a military intervention between 1976 and 1983. [ABSTRACT FROM AUTHOR]

This paper aims at analyzing and comparing two textbooks designed for the third year of High School as regards the way in which they approach the agricultural border advance in Argentina. Both textbooks express the points of view of academic writers, mainly from the field of Geography but also from other Social Sciences as well. Our purpose is to analyze whether the relationship between the type of knowledge proposed by the curriculum of the province of La Pampa and the proposals introduced by the textbooks through the authors’ perspectives is made evident. Departing from this premise, then, we can introduce the following question: Will it be possible to teach and learn this topic from different perspectives and approaches based on the tenets of Social and Critical Geography, taking into account what the National Law of Education (LEN) prescribes? In reference to the proposed aim it will be of crucial importance to promote a comprehensive approach which might lead to a better understanding of the territorial logic of the social subjects. This will in turn lead to understand the different points of view and the multiple dimensions: economic-productive, political, socio-demographic, cultural and environmental which play different roles in the process of soybean production in Argentina’s rural areas, known in Spanish as “sojización.” [ABSTRACT FROM AUTHOR]

Oregano is cultivated in semiarid regions with a negative water balance, therefore is necessary to apply irrigation according water needs. The area of 25 de mayo, La Pampa, which is fed by the Río Colorado, has an irrigation system that makes it suitable for this kind of farming. The goal of this paper was characterize productivity of four oregano ecotypes (Criollo, Mendocino, Cordobés and Compacto) in the irrigated area of 25 de Mayo. Dry matterin flowers and leaves of each ecotype was determined. The results showed that there were no significant differences in yield (p=0.05). However, it should be highlighted that important differences could be observed in the field where, Criollo and Cordobés ecotypes had highest productivity. The yield obtained was highest than in traditional areas, such as Mendoza and Córdoba, which makes the region under study a promising option for oregano production. [ABSTRACT FROM AUTHOR]

This paper represents a contribution to the knowledge about the experience of the Japanese community in rural areas of Argentina, particularly Buenos Aires (state) across the first half of the 20th century. With the objective of updating knowledge about this subject, a comparison was made between communities in peri-urban agricultural colonies: La Capilla, located in Florencio Varela, and Justo José de Urquiza, La Plata. We also focus on the origins, incursions, productive profiles, and the level of participation of Argentine and/or Japanese entities that influenced how each community developed, as well as successful companies and migrant settlement.

Based an ethnographic study on the periphery of the largest and most important irrigated area in central-western Argentina, this paper analyzes the role of persistent ethno-racial and environmental representations that delineate irrigated areas and social groups that possess water and land. The groups located on either side of the most distant irrigation canals are interpellated from modernist paradigms that link water rights, private property, and wine production to European heritage and the idea of progress, while in the non-irrigated area, communal land ownership and pastoralism is associated with indigenous groups of Huarpe descent and the idea of backwardness or regression. Given the fact that both groups are represented as supposedly independent, opposed and separated by the last irrigation canals, this article conceptualizes the latter as an irrigated border. This border, despite being regarded as natural and fixed, is on the contrary artificial and dynamic. It is the product of social and symbolic struggles for water and legitimacy as the socio-cultural group capable of obtaining and controlling water. In this way, not only is the presence of liminal actors who are neither of Huarpe nor European origin highlighted, but also alliances that may lead to the reconfiguration of irrigated areas and sociocultural groups capable of fighting in disputes over natural resources.

The human resource training and knowledge generation adapted to the operating conditions of the various regional productions in Argentina, occupied the attention of experts from the Department of Agriculture, agrarian entities, political and educational sectors, since the early twentieth century. It did not escape this interest a concern about women and farm home. The aim of this paper is to analyze, in this context, the first decades of the "Ramón Santamarina" Farm School of Tandil, an establishment with a rich institutional history that housed the first school of farm home, soon transformed into a farm school and specialized in dairy industry. The transit to the farm household to the preparation of cheese masters, under productivist orientation of schools in the educational proposal of the Department of Agriculture, the social subjects involved, specialization in dairy and its results, are some of the issues discussed, as part of an educational agrarian project not only as a source of labor associated with specific agricultural industries, but also --and perhaps more than anything-- as irradiators of that kind of teaching towards the community.

Due to country requirements or to commercialization standards, in Argentina has increased the number of diagnostic laboratories accredited in the agricultural sector in recent years. These laboratories are also -mostly- directly related to food quality and generally evaluate pesticide residues. The IRAM 301: "General requirements for competence of testing and calibration laboratories" (which is the equivalent to ISO/IEC 17025:2005), is the standard used for testing accreditation through its related entity, and to guarantee the laboratory technical competence. ISTA guidelines, which aim to verify if the testing laboratory is technically competent in order to perform procedures mentioned in its range, can also be applied. In this paper a description of the ISO 17025 and the ISTA guidelines applied to seeds is made, emphasizing strengths, limitations and difficulties for its implementation. We conclude that accreditation is convenient and necessary for achieving value and reliability of results. [ABSTRACT FROM AUTHOR]

This paper falls within the framework of the FAO-INA Agreement that was entered into to "identify new potential irrigated and supplementary-irrigated areas in the basins of northeastern Argentina". The agreement seeks to collect information on monthly reference crop evapotranspiration (ETo), analyze its variability, and show it on isoline maps. The study comprised the central northeastern part of Argentina; the program used was CROPWAT 8.0 – FAO; and climate data were obtained from CLIMWAT 2.0. The information was plotted with ArcView 3.2ª and the variables of interest were interpolated with the Kriging method. Results show that: a) Santiago del Estero is the station with the highest annual ETo: 1767 mm.year-1, while the lowest ETo value is found in Loreto (Misiones) with 1150 mm.year-1; b) the average ETo in January ranges between 160 to 200 mm.month-1, while in July it is between 35 - 90 mm.month-1; c) the average ETo in January in the northeastern part of Cordoba ranges between 165 - 185 mm. month-1 while in July the variability is less pronounced; and d) rainfall in an average hydrological year ranges between 605 and 1825 mm.year-1 with an effective rainfall of 500 and 1400 mm.year-1 that tends to increase towards the northeast.

Agricultural cooperatives are going through a process of restructuring and changing their production model. As a result, they have begun to assume other roles than the classic meaning of cooperativism. However, they are still a system of economic and social organization that is able to combine production development with local and regional economic development. This paper seeks to analyse the specific contribution of the cooperative system to the local and regional rural development process, studying the case and experience of the Unión Agrícola de Avellaneda. The secondary data was obtained from national and provincial sources. Primary information was acquired through a survey of 150 farmers and qualitative information from numerous interviews with economic agents in the area. [ABSTRACT FROM AUTHOR]

This paper addresses the inclusion of agricultural cooperatives in global value chains (GVCs). It focuses on the citrus production system in the southeast of Corrientes province, analysing two export-oriented cooperatives. The study was conducted in a context in which agricultural and food production systems have shifted from a traditional model, based on producing for local markets, to agrifood systems with a global scope. The results of this analysis reveal the importance of strategies to upgrade products, processes and functional aspects, including certification of quality and food safety protocols, investment in technology and brand positioning and marketing in the international context. Together with reshaping internal institutional structures, these strategies have enabled the cases studied to join a buyer-driven GVC where the prevalent form of governance is relational.

At present times, many countries demand quality and added value of the goods they trade. It implies knowledge and technology adaptation in order to obtain agricultural products that are competitive at the international markets. In this regard, Good Agricultural Practices and Social Responsibility regulations, with their certification systems, formally help to demonstrate this "good doing". The aim of this paper is to analyze and promote that Quality Management Systems implementation, particularly Good Agricultural Practices and Social Responsibility regulations, are complementary at being able to comply with the Environmental Law applied to the argentine agricultural area. Its importance focus in that protection, preservation and recognition of the right to a healthy environment before the Constitutional amendment in 1994, was included in the category of the implied rights mentioned in section 33. This was considered as a historical landmark, and was incorporated in the second chapter named "New rights and guarantees", recognized in section 41 including the right to a healthy, equilibrated, suitable to a human development rights, and this directly relates to other rights such as quality of life, development, health, property and information among other.

Legal protection of accumulated and transgenerational developed knowledge by indigenous peoples and local communities, especially those associated with the properties, uses and characteristics of biological diversity, raises some issues and uncertainties. The Intellectual Property Legal Regimen in force, which establishes the basis for the protection of an individual author's work, and the Patent System are not able to protect collective traditional knowledge. The aim of this paper is to discuss not only the limitations that exist in the Argentine legal system to protect them adequately, but also the challenges involved, including from practical problems of registration to deeper issues related to the nature of traditional knowledge and the difficulties to design effective mechanisms to respect the worldview, culture and customary law of the peoples involved and able to prevent their use for commercial applications.

The purpose of this paper is to analyze the female workers' share in the fruit and vegetable labour market in the district of General Pueyrredon, and its articulation with their domestic work, taking into account the characteristics of the workers' households. In this productive space, the transitional female work done in the intensive vegetable crops, which is practiced in the fields and under cover can be proved, as well as in non-traditional fruit crops. Women participate in basic cultural works, especially, in harvesting and selection, conditioning and packing of fruits and vegetables. It is observed how women develop different strategies in order to make both work and family worlds compatible, without disregarding the responsibilities related to the domestic and reproduction duties that determine their possibilities of labour insertion.

Due to the deepening capitalist nature of agricultural production in the pampas region, family farms have had to deal with bigger demands in order to continue working as commodity producers. Even though stressful tendencies have prevailed, the process has not led to the disappearance of this type of production units. This brings up the question about how they have managed to deal with increasingly hostile contexts. In order to answer that question, and trying to find out the clues to their persistence, in this paper we analyze the economic and productive strategies carried out by a group of eleven farmer families of Puan and Adolfo Alsina districts (located in SouthWest Buenos Aires), between the late 1980s and today. Using a qualitative and exploratory approach, we study their economic and productive options taking into account both structural factors - such as labour force organization and land and capital integration- and subjective and cultural aspects.

Vinal (Prosopis ruscifolia G.) is a highly-tolerant to saline stress species of forest-importance native to the Western Chaco Phytogeographical Region. The aim of this paper was to test the hypothesis that supplementing vinal seedlings with CaSO4 lowers their concentration of toxic ions and increases proline concentration allowing for osmotic adjustment. The seedlings were cultivated in a 25% Hoagland solutions whether adding 0.4 mol L-1 of NaCl or not, and whether supplementing it with 5 or 10 mmol L-1 of CaSO4 or not. Both dry matter, mineral composition, relative water content and proline and soluble sugar concentrations were determined. A totally randomized experimental design was used with five repetitions and the results analyzed with ANOVA and the Tukey test. The results obtained endorse the protecting role of Ca+2 by maintaining Ca+2, K+, and Mg+2 concentrations in tissues; the Na+ absorption inhibition; and the osmotic adjustment by synthesizing osmocompatible solutes.

This paper presents and analyzes the archaeological data recovered in Guasapampa Valley (province of Cordoba, Argentina), which consists mainly of engraved and painted rock art panels. The forested mountain landscape has numerous species of trees and shrubs with edible fruits, but it is distinguished by a scarcity of water resources. During the late Prehispanic period (ca. 1400-400 B.P.) the Guasapampa Valley was occupied seasonally by groups established most of the year in the fertile valleys of the east, in agricultural oases up to 20 and 40 km away. The data recovered are significant because they allow us to understand the role of rock art as an active medium for the establishment, negotiation, and reproduction of certain social ties between producers and observers. In this regard, we assume a comparative perspective that allows us to identify particularities of the occupations of southern and northern sections of the valley, especially the features that define the contexts of production and meaning of the art. The differences identified in each section of the valley refer to contrasts and oppositions in the social practices surrounding and produced by this materiality. Thus, we consider the elements that support its definition on the one hand as a means to convey the significance of particular places among minimal affiliational groups who build an open, shared social landscape in the case of the southern section, and on the other hand as territorial markers in the north related to the existence of limits and restrictions on movement and access to resources, including seasonal water wells.

The present paper results from a research project of wider scope, Rural Territorial Development. Territorial management in the Guatraché Department, La Pampa, which shows the findings of research carried out in the Guatraché Department, in the Province of La Pampa. The project aims at producing a panorama of the agricultural activity of this area from the beginnings of the process of colonization in 1879 -which marks the occupation of the territory after the clearing of the aborigines, coinciding with the end of the “Desert Campaign"-, until the present time –which is framed by the complexity of globalization. The province of La Pampa, at that time Territory of Central La Pampa, with its East and South East areas showing climate and soil parameters suitable for the above-mentioned activities, turned into the setting of an intense colonization sustained by various railway companies, pillars of the economic system prevailing in the Argentine Republic in late nineteenth and early twentieth century. As part of this territory, the Guatraché Department was the scenario of an important agricultural and stockbreeding activity -this being so at least until the start of severe climate crises which, along with international events (the Second World War) disrupted the model. After the former, the diversification of farming complemented with stockbreeding, where sheep were gradually replaced by cattle, characterized the activity until the nineties. At that time, a new international scenario marked by globalization, with the liberation of the markets and state decentralization, formed part of the neo-liberal politics of the times. The rural sector was also part of the process and its consequences. [ABSTRACT FROM AUTHOR]
