Análisis del proceso de negociación e implementación del TLC entre chile y EE.UU. y su articulación con el régimen internacional de comercio en el sector de la minería

El objetivo del presente estudio de caso es identificar los mecanismos, normas y reglas empleados durante la negociación e implementación del TLC entre Chile y EE.UU. y su articulación con el Régimen Internacional de Comercio en el sector de la minería chilena. De esta manera se analizarán históricamente las principales condiciones políticas y económicas de Chile y EE.UU. que propiciaron la negociación e implementación de un acuerdo entre estas dos economías asimétricas. Así durante el proceso de negociación del TLC se describirán los elementos que se adaptaron a los principios y normas de la Organización Mundial de Comercio, logrando establecer un TLC entre las dos naciones. Finalmente se examinan algunos efectos que tuvo en el sector minero chileno, la puesta en marcha de acuerdo de libre comercio, teniendo en cuenta que dicho sector es altamente sensible para la economía del país latinoamericano.

Las pretensiones geoestratégicas de Colombia luego de su adhesión al Tratado Antártico en 1989

El interés de esta investigación es analizar los antecedentes y desarrollo del interés colombiano en la Antártida, así como la relación de cooperación colombo-chilena y la importancia geoestratégica del continente blanco, a partir de diferentes conceptos: geoestrategia, política exterior colombiana y cooperación internacional. Teniendo en cuenta que la Antártida refleja los intereses geoestratégicos de muchos países desde comienzos del siglo XX, Colombia no puede dejar de lado sus aspiraciones en el Sistema Internacional y por esta razón decide ingresar al Tratado Antártico en 1989, sin embargo, es necesario definir cuáles son las pretensiones geoestratégicas del país suramericano en este territorio y precisar la probabilidad de su cambio de estatus en el mismo que le permita obtener provechos materiales de forma unilateral en materia de recursos, actividad diplomática, política exterior y posición geográfica.

Caracterización de los hábitos alimentarios en población pediátrica de cuatro instituciones escolares

Introducción: La obesidad infantil ha venido en aumento en los últimos años y Colombia no es ajena a esta problemática. Uno de los lugares para intervención son los planteles educativos, en los cuales los escolares son quienes escogen sus alimentos. En el presente estudio se pretendió caracterizar los hábitos alimentarios de una población pediátrica en cuatro instituciones educativas, con el fin de conocer las prioridades infantiles en cuanto a la escogencia de los alimentos, y por ende generar recomendaciones. Metodología: Se realizó un estudio descriptivo multicéntrico que presenta los resultados de encuestas dirigidas a escolares entre 8 y 18 años, usuarios de tiendas escolares. Se realizó un análisis descriptivo de acuerdo a las preferencias de alimentación por institución, por género y por edad entre otros. Resultados: Se incluyeron un total de 512 escolares. La distribución por género y edad fue similar en las cuatro instituciones educativas. Entre los alimentos de preferencia predominaron los alimentos empaquetados, pizza, helados y en menor proporción las frutas. En cuanto a las bebidas predominó la gaseosa y té en botella. Entre las razones para escoger los alimentos predominó “el sabor” seguido de la “facilidad y rapidez” para su consumo; y la principal razón para no escoger los alimentos fue el precio. Discusión: Es necesario hacer intervención desde una temprana edad para generar hábitos de alimentación saludable y equilibrada, al igual que se debería tener un programa de detección de hábitos alimentarios inadecuados en las instituciones escolares para así poder combatirlos.

Notas sobre la presencia mapuche en la literatura chilena (Crítica)

Mauricio Ostria revisa la manera en que el mapuche es presentado en la literatura chilena. Durante la Colonia, ciertos rasgos de los indios mapuches resaltados por La Araucana, de Alonso de Ercilla (valor, rebeldía, destino épico de resistencia), contribuyeron a configurar la identidad del pueblo chileno. Durante la república, la percepción camina entre la admiración y la conmiseración, y el desprecio por el excluido. En el siglo XX predomina la exclusión, la idea del mapuche como un ser moralmente degradado, sin embargo, poetas como Gabriela Mistral y Pablo Neruda se aproximan con distintos puntos de vista, apartados del desprecio. A fines del siglo XX, la mirada multicultural inicia una literatura que pretende dar voz al mapuche, escritores de esta línea son Violeta Cáceres, Clemente Riedemann, y poetas de origen mapuche, como Jaime Luis Huenún, Leonel Lienlaf, Elicura Chihuailaf («la más reflexiva, la más polémica, la más lúcida de las voces mapuches, la más consciente de la función de resistencia e identidad cultural»), son los que más luchan por una nueva percepción del mapuche que, aun ahora, es visto por la sociedad chilena como héroe, bárbaro o víctima.

El extravío del poeta: notas sobre la escritura de Roberto Bolaño (Crítica)

El autor reflexiona sobre una constante en la narrativa del escritor chileno Roberto Bolaño: sus personajes poetas –de muy diversa índole moral y ocupacional– se desplazan de un lugar a otro, en exilio o peregrinaje, en busca de un escritor ausente, nunca lo encuentran, o éste muere antes de que se establezca la comunicación. La práctica de la escritura, problemática por sí misma, convierte al poeta en un ser perdido o en tránsito, extraviado, un ser vacío que escribe «bajo hipnosis», un secretario que toma nota de los sueños y pesadillas de otro, que únicamente discute con algún fantasma sobre la pertinencia de los párrafos que se repiten. El acto de escribir se convierte, en la obra de Bolaño, en un escenario marcado por el vacío y el exilio.

Globalización, ecología y literatura. Aproximación ecocrítica a textos literarios latinoamericanos (Crítica)

Se examinan algunas prácticas textuales literarias latinoamericanas, caracterizadas por presentar visiones profundas de los sujetos humanos y la naturaleza. Se indaga en ellas tanto las relaciones de los sujetos con su medio y la presencia de una conciencia ecológica activa, como la plasmación discursiva de un imaginario vinculado a esa conciencia relacional: la plasmación de vivencias de profunda integración del ser humano con el cosmos. Se indaga tanto los referentes ambientales como la articulación de elementos de la naturaleza en tanto expresión de los sujetos textuales.Todo en el marco de los procesos de globalización y la defensa de los valores culturales regionales.

A survey of dairy effluent management in the south of Chile

A survey was carried out on 55 commercial dairy farms located in the South of Chile during 1995-97. A questionnaire was developed to obtain informed estimates of dairy effluent management on those farms. Information was analysed on an annual basis using a computer spreadsheet linking all the parameters surveyed. In addition, slurry samples were taken for analysis of dry matter content (DM). Herd size varied between 50 and 800 cows per farm. A large proportion of the total volume of effluents produced came from rainfall (46%), dirty water accounted for 29% with only 25% from cow's faeces and urine. The large volume of effluents produced resulted in a reduced storage capacity (on average of 2 months) or more frequent and higher application rates to the field. Only 37% of the farmers knew the application rates of manure and there was a wide range in the quantity used per year (12 m(3)/ha to 300 m(3)/ha). Dairy effluents were applied mainly on grass (71%) throughout the year but, mostly concentrated during the winter and spring time using only surface irrigation system. The total solids contents of effluents was very low, with 62% of the samples being <4% DM. This reflected the large volumes of clean water that the storage tanks received. The information collected has identified problems in effluent management in Chilean dairy farms where research and technology transfer will be necessary to avoid pollution problems.

Analysis of the headspace aroma compounds of walnuts (Juglans regia L.)

The aroma volatiles of walnuts from three different geographical locations were studied. Over 110 compounds were identified in the headspace volatiles, many for the first time as walnut components. Walnuts from China and the Ukraine contained high levels of lipid-derived volatiles, in particular hexanal, pentanal, 1-hexanol and 1-pentanol from linoleic acid breakdown, and 1-penten-3-ol from alpha-linolenic acid breakdown. Chilean walnuts, however, contained high levels of alkylbenzenes of molecular weight 120, with the lipid-derived aldehydes and alcohols present at much lower levels than in the other two walnut samples. The relationship between the fatty acid composition of the walnuts and their volatile composition is discussed. Copyright (C) 2005 John Wiley & Sons, Ltd.

Power, nature and neoliberalism: the political ecology of water in Chile

Since the 1990s, international water sector reforms have centred heavily on economic and market approaches. In regard to water resources management, tradable water rights have been promoted, often supported by the neoliberal model adopted in Chile. Chile's 1981 Water Code was reformed to comprise a system of water rights that could be freely traded with few restrictions. International financial institutions have embraced the Chilean model, claiming that it results in more efficient water use, and potentially fosters social and environmental benefits. However, in Chile the Water Code is deeply contested. It has been criticised for being too permissive and has produced a number of problems in practice. Moreover, attempts to modify it have become the focus of a lengthy polemic debate. This paper employs a political ecology perspective to explore the socio-environmental outcomes of water management in Chile, drawing on a case study of agriculture in the semi-arid Norte Chico. The case illustrates how large-scale farmers exert greater control over water, while peasant farmers have increasingly less access. I argue that these outcomes are facilitated by the mode of water management implemented within the framework of the Water Code. Through this preliminary examination of social equity and the environmental aspects of water resources management in Chile, I suggest that the omission of these issues from the international debates on water rights markets is a cause for concern.

Fenced in: Common property struggles in the management of communal rangelands in central Eastern Cape Province, South Africa

This paper takes as its starting point the assertion that current rangeland management in the central Eastern Cape Province (former Ciskei) of South Africa, is characterised primarily by an ‘open access’ approach. Empirical material drawn from three case-study communities in the region is used to examine the main barriers to management of rangeland as a ‘commons’. The general inability to define and enforce rights to particular grazing resourses in the face of competing claims from ‘outsiders’, as well as inadequate local institutions responsible for rangeland management are highlighted as being of key importance. These are often exacerbated by lack of available grazing land, diffuse user groups and local political and ethnic divisions. Many of these problems have a strong legacy in historical apartheid policies such as forced resettlement and betterment planning. On this basis it is argued that policy should focus on facilitating the emergence of effective, local institutions for rangeland management. Given the limited grazing available to many communities in the region, a critical aspect of this will be finding ways to legitimise current patterns of extensive resource use, which traverse existing ‘community’ boundaries. However, this runs counter to recent legislation, which strongly links community management with legal ownership of land within strict boundaries often defined through fencing. Finding ways to overcome this apparent disjuncture between theory and policy will be vital for the effective management of common pool grazing resources in the region.

Contested institutions? Traditional leaders and land access and control in communal areas of Eastern Cape Province, South Africa

The South African government has endeavoured to strengthen property rights in communal areas and develop civil society institutions for community-led development and natural resource management. However, the effectiveness of this remains unclear as the emergence and operation of civil society institutions in these areas is potentially constrained by the persistence of traditional authorities. Focusing on the former Transkei region of Eastern Cape Province, three case study communities are used examine the extent to which local institutions overlap in issues of land access and control. Within these communities, traditional leaders (chiefs and headmen) continue to exercise complete and sole authority over land allocation and use this to entrench their own positions. However, in the absence of effective state support, traditional authorities have only limited power over how land is used and in enforcing land rights, particularly over communal resources such as rangeland. This diminishes their local legitimacy and encourages some groups to contest their authority by cutting fences, ignoring collective grazing decisions and refusing to pay ‘fees’ levied on them. They are encouraged in such activities by the presence of democratically elected local civil society institutions such as ward councillors and farmers’ organisations, which have broad appeal and are increasingly responsible for much of the agrarian development that takes place, despite having no direct mandate over land. Where it occurs at all, interaction between these different institutions is generally restricted to approval being required from traditional leaders for land allocated to development projects. On this basis it is argued that a more radical approach to land reform in communal areas is required, which transfers all powers over land to elected and accountable local institutions and integrates land allocation, land management and agrarian development more effectively.

The sociocultural contexts and meanings associated with livestock keeping in rural South Africa

This paper complements Vetter’s position paper, ‘Development and sustainable management of rangeland commons – aligning policy with the realities of South Africa’s rural landscape’ (Vetter in this issue). It seeks to advance the debate regarding the contemporary nature of livestock keeping in South Africa. It sheds some anthropological light on the role of ‘culture’ in accounting for people’s values and practices in relation to livestock and reflects on the implications of this for policy-making in this area.

Options for support to agriculture and food security under climate change

Agriculture and food security are key sectors for intervention under climate change. Agricultural production is highly vulnerable even to 2C (low-end) predictions for global mean temperatures in 2100, with major implications for rural poverty and for both rural and urban food security. Agriculture also presents untapped opportunities for mitigation, given the large land area under crops and rangeland, and the additional mitigation potential of aquaculture. This paper presents a summary of current knowledge on options to support farmers, particularly smallholder farmers, in achieving food security through agriculture under climate change. Actions towards adaptation fall into two broad overlapping areas: (1) accelerated adaptation to progressive climate change over decadal time scales, for example integrated packages of technology, agronomy and policy options for farmers and food systems, and (2) better management of agricultural risks associated with increasing climate variability and extreme events, for example improved climate information services and safety nets. Maximization of agriculture’s mitigation potential will require investments in technological innovation and agricultural intensification linked to increased efficiency of inputs, and creation of incentives and monitoring systems that are inclusive of smallholder farmers. Food systems faced with climate change need urgent, broad-based action in spite of uncertainties.
