A sedimentary and micropaleontological study of the Quillagua Formation provides a detailed paleohydrological reconstruction of the lacustrine system which occupied the present-day hyperarid Quillagua-Llamara fore-arc Basin (Northern Chile) from lattermost Miocene to Early Pliocene times.

Fruit production in Chile: bright past, uncertain future

In 2007 (the last agricultural census), Chile had 308, 445 ha of fruit orchards: an increase of almost 32% from the previous census (1997). The most important species were table grapes (20%), avocados (13%) and apples (12%). Some 22% of the fruit crops growing area corresponded to juvenile orchards; within the species with higher proportion of juvenile orchards were prunes (42%) and blueberries (56%). Most orchards are located between latitude 27º18` S (Copiapó) and 40º36´S (Puerto Varas). The industry is driven by the export component which accounts for more than 50% of the fruits produced. In the crop season 2009-2010, approximately 254 million boxes (around 2.5 million tons) were exported, representing over US$ 3.5 million. Processed and fresh fruits represented 8.2 and 26.7% of the total forest and agricultural Chilean exports in 2008, respectively. The main markets for this fruits were USA/Canada (42%) and Europe (32%). The fruit grower receives, on average, 12-16% of the total price of the fruit in its final destination. Each year the fruit industry employs 450.000 people directly, of which 1/3 are permanent. Even though the fruit industry employs the highest proportion of the agricultural labor and the growing area has increased in the last 20 years, the proportion of agricultural employment has decreased from 19.5% in 1989 to 10.8% in 2008. It might also be noted that Chile invests only 0.7% of the GDP in research. In the last 40 years, the fruit industry has been a motor for the Chilean economic development, but the lower rates of currency exchange, the rising costs of energy (oil, electricity), and the increasing scarcity of hand labor have drastically reduced the profitability and are putting at risk the viability of a large proportion of the fruit orchards in Chile. It is estimated that this season around 65% of the orchards will have a negative economic balance in their operations. Higher investment in research, improvements in fruit quality and various orchard management practices, as well as higher financial support from the Government are needed for the long term viability of the fruit industry in Chile.

Electric Motor and Frequency Converter Markets in Latin America and Especially in the Mining Industry of Chile

Latinalaisen Amerikan osuus maailmantaloudesta on pieni verrattuna sen maantieteelliseen kokoon, väkilukuun ja luonnonvaroihin. Aluetta pidetään kuitenkin yhtenä tulevaisuuden merkittävistä kasvumarkkinoista. Useissa Latinalaisen Amerikan maissa on teollisuutta, joka hyödyntää luonnonvaroja ja tuottaa raaka-aineita sekä kotimaan että ulkomaiden markkinoille. Tällaisia tyypillisiä teollisuudenaloja Latinalaisessa Amerikassa ovat kaivos- ja metsäteollisuus sekä öljyn ja maakaasun tuotanto. Näiden teollisuudenalojen tuotantolaitteiden ja koneiden valmistusta ei Latinalaisessa Amerikassa juurikaan ole. Ne tuodaan yleensä Pohjois-Amerikasta ja Euroopasta. Tässä diplomityössä tutkitaan sähkömoottorien ja taajuusmuuttajien markkinapotentiaalia Latinalaisessa Amerikassa. Tutkimuksessa perehdytään Latinalaisen Amerikan maiden kansantalouksien tilaan sekä arvioidaan sähkömoottorien ja taajuusmuuttajien markkinoiden kokoa tullitilastojen avulla. Chilen kaivosteollisuudessa arvioidaan olevan erityistä potentiaalia. Diplomityössä selvitetään ostoprosessin kulkua Chilen kaivosteollisuudessa ja eri asiakastyyppien roolia siinä sekä tärkeimpiä päätöskriteerejä toimittaja- ja teknologiavalinnoissa.

Blueberry production in Chile: current status and future developments

Chile has become a major actor in the blueberry industry as the most important supplier of off-season fresh fruit for the northern hemisphere. Blueberry exports passed from US$ 30 million (around 4,000 tons) in 2000 to US$ 380 million (94,000 tons) in 2011. The characteristics of the major blueberry growing regions (North, Central, South-central and South) are presented in terms of acreage, varieties, management practices, extension of the harvest season, and soil and climatic conditions. Most fruit is from highbush varieties, picked by hand and exported fresh by boat to United States. Largest proportion of fruit is exported from mid December to late January, which coincides with lowest prices. The south-central region (latitudes 34º50' to 38º15' S) was in 2007 the most important one with 5,075 ha (51.1% of area planted). Among the challenges for the Chilean blueberry industry in the near future are: 1. Lower profitability due to lower rates of currency exchange and higher costs, 2 - Greater scarcity and higher cost of labor, 3.- Need for higher productivity and sustainable production practices, 4- Fruit of high and consistent quality, and 5.- Greater investment in research. As a case study the article presents three approaches that can help identify areas with low availability of labor and improve its efficiency. The article shows the use of geomatic tools to establish labor availability, application of growth regulators to reduce crop load, increase fruit size and improve harvest efficiency, and the use of shakers to harvest fresh fruit for long distance markets. More research is needed to improve yields, reduce costs and give greater economical and ecological sustainability to the Chilean blueberry industry.

The kiwifruit in Chile and in the world

The kiwi is a fruit that, has only been in Europe for about 60 years, which signifies a great potential for the development of its consumption and great difficulty in the educational process of the product. Currently there is a growing increase in world production, which to date is above the growth in demand. This means that the kiwi categories are not growing significantly and, on the contrary, the kiwi is at a crossroad that will be resolved in the coming years. The changing global economic scenario affects high-value products such as kiwis, making it hard to predict their commercial results. The worldwide market has clearly indicated through the demand and the prices that it is interested in the sweeter yellow varieties. Asian markets have been and are expected to continue to grow. The increase in world production has also generated overlap in stocks between the hemispheres, which makes it necessary to closely monitor commercial strategies regarding the start and end of the season. In this way, the market entry of the southern hemisphere kiwifruit is conditioned according to the presence of fruit from the Northern Hemisphere. The unique features and uses of the kiwi make it one of the most interesting fruits present in the world. For this reason it is also a fruit with high purchase value. In spite of the described variables and market trends, there is a growing demand for consuming better quality kiwis and willingness to pay a higher price.

Regeneración urbana en Chile y Cataluña. Análisis de estrategias en fases de diseño e implementación

Las ciudades evidencian procesos degenerativos y de desigualdad como resultado del ajuste político-económico a la globalización. Consecuencias de este fenómeno se observan a nivel barrial, lo que no es sólo el resultado del abandono de ciertas áreas sino, frecuentemente, es consecuencia directa o indirecta de acciones públicas. Los gobiernos están desarrollando políticas públicas y acciones para la regeneración de áreas deterioradas, con objetivos diversos, destacando la cohesión social como una prioridad. Este artículo se propone comparar y analizar las intervenciones desplegadas en Cataluña (Llei de Barris) y Chile (programa Quiero mi Barrio). Ambas iniciativas declaran basarse en enfoques integrales, por lo que resulta importante analizar la existencia de mecanismos para la coordinación e implementación de acciones transversales -sociales, físicas y/o económicas- que requieren acciones consorciadas y la inclusión de los principales actores concernidos. Una preocupación del equipo investigador es indagar en la relación entre el diseño de esas políticas y su traducción en prácticas efectivas.

HARVEST LABOR QUALITY AND PRODUCTIVITY:CASE STUDY OF CHERRY GROWING IN CHILE

In Chile, the cherry tree has been one of the fastest growing and most profitable crops in the last ten years. However, increasing production costs, the scarcity of hired labor, and unfavorable exchange rates have reduced the productivity and competitiveness of the Chilean fruit sector. The aim of this article is to evaluate the harvest labor quality in cherry growing in Chile through the use of productivity indicators. A harvest labor evaluation system (HLES) was designed and four indicators were measured: Average Weight of Harvested Box, Average Daily Production per Worker, Percent of Export Fruit, and Percent of Fruit Discarded. Significant differences werefound between the 2010/11 season (with the HLES implementation) and the previous seasons without HLES. The average worker yield, average weight of a filled box, and fruit quality improved, while the amount of discarded fruit decreased. Hired labor management in agriculture is crucial for improving the productivity of the fresh fruit export producers. The use of HLES and the adoption of new technologies could help to solve the competitiveness problem in the Chilean fruit sector.

INCLUDING RISK IN ECONOMIC FEASIBILITY ANALYSIS:A STOCHASTIC SIMULATION MODEL FOR BLUEBERRY INVESTMENT DECISIONS IN CHILE

ABSTRACT The traditional method of net present value (NPV) to analyze the economic profitability of an investment (based on a deterministic approach) does not adequately represent the implicit risk associated with different but correlated input variables. Using a stochastic simulation approach for evaluating the profitability of blueberry (Vaccinium corymbosum L.) production in Chile, the objective of this study is to illustrate the complexity of including risk in economic feasibility analysis when the project is subject to several but correlated risks. The results of the simulation analysis suggest that the non-inclusion of the intratemporal correlation between input variables underestimate the risk associated with investment decisions. The methodological contribution of this study illustrates the complexity of the interrelationships between uncertain variables and their impact on the convenience of carrying out this type of business in Chile. The steps for the analysis of economic viability were: First, adjusted probability distributions for stochastic input variables (SIV) were simulated and validated. Second, the random values of SIV were used to calculate random values of variables such as production, revenues, costs, depreciation, taxes and net cash flows. Third, the complete stochastic model was simulated with 10,000 iterations using random values for SIV. This result gave information to estimate the probability distributions of the stochastic output variables (SOV) such as the net present value, internal rate of return, value at risk, average cost of production, contribution margin and return on capital. Fourth, the complete stochastic model simulation results were used to analyze alternative scenarios and provide the results to decision makers in the form of probabilities, probability distributions, and for the SOV probabilistic forecasts. The main conclusion shown that this project is a profitable alternative investment in fruit trees in Chile.

Freshwater biodiversity and conservation in mediterranean climate streams of Chile.

In Chile, mediterranean climate conditions only occur in the Central Zone (ChMZ). Despite its small area, this mediterranean climate region (med-region) has been recognised as a hotspot for biodiversity. However, in contrast to the rivers of other med-regions, the rivers in the ChMZ have been studied infrequently, and knowledge of their freshwater biodiversity is scarce and fragmented. We gathered information on the freshwater biodiversity of ChMZ, and present a review of the current knowledge of the principal floral and faunal groups. Existing knowledge indicates that the ChMZ has high levels of endemism, with many primitive species being of Gondwanan origin. Although detailed information is available on most floral groups, most faunal groups remain poorly known. In addition, numerous rivers in the ChMZ remain completely unexplored. Taxonomic specialists are scarce, and the information available on freshwater biodiversity has resulted from studies with objectives that did not directly address biodiversity issues. Research funding in this med-region has a strong applied character and is not focused on the knowledge of natural systems and their biodiversity. Species conservation policies are urgently required in this highly diverse med-region, which is also the most severely impacted and most populated region of the country.

The long run development of Chile and the Natural Resources curse. Linkages, policy and growth, 1850-1950

This chapter analyses the effects of Natural Resources on the Chilean economy in the long run -1850-1950-. Specifically, the authors focus their attention on the mining cycles -nitrates and copper- and their impact on the mining activity. We also compare it with the evolution of the industry and whole economy, and how this has affected the economic growth of the country. In that sense, the industrial performance in Chile at the end of the 19th century until the Great Depression is still under debate. The optimistic view of Kirsch -1977- forehead the pessimistic view of Lagos -1966- and Palma -1979-. The new data and its analyses shows a neutral effect of the Natural Resources in the industrial development.

La investigación en Comunicación ante una encrucijada: de la teoría de los campos a la diseminación y diversidad gnoseológica. Estudio inicial comparado entre España, Brasil y Chile

Desde sus inicios, la comunicación fue un espacio de investigación diver - so, complejo, atravesado por múltiples influencias (sociológicas, políticas, económicas y semióticas). En ese contexto, la teoría de los campos (apun- talada por Pierre Bourdieu) brindó las posibilidades de estructuración y de autonomía, como mecanismo de reducir esa diversidad. Sin embargo, en estos años la heteronomía del campo, ha conducido a la comunicación 804 La investigación en Comunicación ante una encrucijada: ... - Víctor Silva Echeto, Jordi de San Eugenio Vela (como en el caso del arte u otras disciplinas) a influenciarse por contextos globales, inter y transdisciplinarios e intermediales (o transmediales), por tanto, no son los medios su objeto de investigación en sí mismos, sino una diversidad gnoseológica. En el artículo, se pone en discusión estos aspec- tos teóricos, contrastándolos con un estudio comparado –inicial– sobre la investigación en comunicación en España, Brasil y Chile, tres de los países con un mayor desarrollo en los últimos años.
