This paper deals with the explorations conducted by the Welsh settlers in Patagonia since their settlement in 1865. Appealing to mostly unpublished sources, explorations of the early years are especially detailed, as well as their motivations and their consequences.  It is shown that from the very beginning the westbound was perceived as the most favorable and desirable, which anticipate the expansion of the Welsh Colony in this direction some decades later. A classification of the exploratory trips is proposed based on the period and their causes.

Hourly mean values of equivalent temperatures were obtained from the series 1975-86 in Punta Arenas (53°S; 71°W). Mean annual cooling effect was calculated in 1,6°C. Daily and annual variations of equivalent temperatures were analyzed according to the Wace method (Wace 1990).  Results show that oceanic features of the thermal regime of that area are enhanced because of the wind. Several climatic indices were employed to quantify this phenomenon.

En este trabajo se analizan las exploraciones que los colonos galeses realizaron en la Patagonia desde su instalación en ella en 1865. Apelando a fuentes mayormente inéditas, se detallan especialmente las exploraciones de los primeros años, sus motivaciones y sus consecuencias. Se muestra que desde el comienzo el rumbo oeste era percibido como el más favorable y deseable, lo que anticiparía la expansión de la colonia galesa en esa dirección décadas más tarde. Se propone una clasificación de las exploraciones en base al período y las causas de su realización.This project deals with the explorations conducted by the Welsh settlers in Patagonia since their settlement in 1865.

The uniqueness of Patagonia stems not only from its remote location on the world map but from several other geographic factors briefly discussed on this chapter, starting from some climatic features and sharp contrasts not found anywhere else. The last glaciation caused drainage deviations that complicated international boundary delimitation, which, in turn, hastened expansionism based on sheep farming of not always suitable lands. Widespread desertification is the major ecological consequence of this unwise process, developed at the expense of Native Patagonian peoples, some of whom have completely disappeared. From a terrestrial point of view, Patagonia is a geographic cul-de-sac, so aboriginal cultures were materially rudimentary; on the other hand, to seafarers Patagonia was on the inter-oceanic route and was a dangerous coast to be left behind as soon as possible. The unavoidable contact was dramatically contrasting and not always peaceful. With very low demographic density, and despite isolated cases of ecological mismanagement, the region still keeps an aura of pristine nature, enhanced by distance and legend. This chapter may seem incongruent in this volume, but it aims to place the readers in the wider scope of Patagonian geo-history, the human environment in which the research presented here was carried out.

On the basis of research conducted in three contrasting South American ecoregions (southern Patagonia, Argentina; the central Pampas and Campos, Uruguay; and western Amazonia, Brazil), this chapter aims to better understand the complex sets of reasons that have recently led local societies to adopt more sustainable pasture management in South America. After a brief overview of each of the three biomes, representative social–ecological systems of pastoralism are identified with the objective to describe their respective pasture management history, especially the colonization process and the settlement of the pioneers, and the successive farming systems, mainly the practices related to herd and pasture management, are compared. Finally, the main local and national policies regarding the livestock sector and landownership are analyzed. The evolution of the social–ecological systems of pastoralism in these ecoregions was assessed with a three-dimensional model of vulnerability based on the agroecosystem resilience, livelihood improvement, and institutional capability. The evolution of the mental models about livestock has also been analyzed to better understand the current perceptions of the local people and their scenarios for the future of livestock in their social–ecological systems. The results focused on the dynamics of rangeland management, the vulnerability of the pastoral social–ecological systems, and the evolution of the mental models of local people about livestock, so as to discuss the different rhythms of transformation and the existence of critical thresholds. Besides diverse land and social issues, it is imperative to intensify livestock production and increase the offer of new technologies, as well as to identify some relevant human dimension factors, such as the demand of local societies for collective livelihood improvement, the recent national and international environmental policies related to global warming and biodiversity, and the stronger awareness of consumers for sustainable development. In the context of global change, the practices of rangeland management will change in a more sustainable way, resulting in better society–environment interaction and human–nature integration.

ABSTRACT Although widely used elsewhere, multivariate analysis of temperature is not often explored to evaluate temperature patterns in Patagonia, the southern tip of South America. Since there is no general agreement in locating this region within a global temperature-based climatic scheme, classifying temperature regimes using cluster analysis can lead to a better understanding of the Patagonian climate. Working with 14-year long series of daily temperature data in 21 weather-stations south of 40°S, an average linkage clustering is presented within the matrix of correlation among the departures from the monthly temperature averages. Four clusters were identified at the r=0.55 level, the mapping of which is consistent with some ecoclimatic boundaries. This was an unexpected result as deviations rather than actual temperature levels were employed to perform the clustering. Also, the two major clusters adopted a zonal disposition regardless of the main climatic division in Patagonia, i.e. west-east. In this way it is shown that this orography-induced boundary, is merely rain-dependent with little consequence to the temperature regime. Standard deviation of mean annual temperature was also mapped as a complementary tool to depict the oceanic-continental continuum in the area, upon which no uniform criterion exists. Finally, the weather-station that best reflects the interannual variation of temperature was identified in each one of the two main clusters. The correlation among both base stations and the others, showed two extensive homogeneous areas that cover most of Patagonia, while two marginal areas exhibit separate patterns.

The spatial variation of nitrogen availability, mineralization, and immobilization was studied in heavily grazed areas of the Larrea divaricata and Stipa spp. steppe in northern Patagonia in order to identify the interactions between the nitrogen pool and vegetation. For this purpose, four of the most predominant types of vegetation patches and neighboring bare soil patches were selected for study. Soil

Peninsula Valdes shares with the whole of Eastern Patagonia the main features of the regional climate, i.e. scarce rainfall, strong winds and cool-temperate temperatures. Not with standing it has an ill-defined climate because of its geographical location not far from the transitional area, where Pacific and Atlantic air masses merge. Also, because of its latitude (42°–43° S), the southward migration of the subtropical anticyclones is still noticeable over the area in summer. This chapter aims to explain the interplay between large scaled factors as the above-mentioned, and local ones as the almost insularity of the study area. A concise description of the climate is presented through the usual basic elements, temperature, precipitation, and wind. The maritime influence upon these variables is evaluated. It is shown that although mostly commanded by the rain-shadowed westerlies as the entire Patagonia, the climate of Peninsula Valdes has singularities that make it a less arid, more even, and milder climate which presents some Mediterranean features. Historic trends of rainfall and temperature are discussed and appear to be in agreement with global warming projections, according to which future scenarios would be drier and warmer in the Peninsula Valdes region.

The occurrence of windy conditions in Patagonia is well known. However there has been little attempt made concerning the wind cooling effect in the area. Because of windchill, equivalent temperatures may be quite different to the actual temperature. In Patagonia, constancy and wind strength determine a yet unexplored bioclimatic factor. This paper deals with windchill and the resulting equivalent temperatures

La Patagonie est la région la plus australe du continent américain. Elle s’étend entre 36° et 56°de latitude S, et le Cap Horn est situé à moins de 1 000 kilomètres de l’Antarctique. Par sa position, la région se trouve au milieu d’un courant de vents d’ouest dont la progression ne rencontre pas d’obstacle et qui concentrent ainsi une force et une persistance incon‐nues dans l’hémisphère Nord. Ces latitudes, appelées « les 40es rugissants » ou « les 50es hurlants » par les anciens ma‐rins, étaient synonymes de barrières quasi infranchissables à l’époque de la navigation à voile. Tout cela a fini par forger la mauvaise réputation de cette terre inhospitalière et dé‐solée qu’il fallait contourner pour atteindre l’océan Pacifique. La cordillère des Andes, per‐pendiculaire aux vents soufflant du Pacifique, joue un rôle très efficace de barrière de con‐densation et crée un contraste marqué entre la Patagonie occidentale, boisée et très hu‐mide dont une étroite bande appartient au Chili, et la Patagonie orientale, steppique et semi‐désertique qui appartient à l’Argentine.Fil: Coronato, Fernando Raul.

L’établissement d’une colonie galloise en Patagonie, dans le sud de l’Argentine, dans la seconde moitié du XIXe siècle, est une aventure qui se perpétue encore aujourd’hui. Ces colons faillirent bien être rejoints par d’autres, venus d’Armorique. C’était du moins le souhait de l’écrivain
celtisant Charles de Gaulle (l’oncle du général). A travers le courrier de ce dernier et de ses correspondants gallois, cet article nous fait revivre les vicissitudes de ce projet avorté.

La percepción de la cordillera de los Andes al comienzo de la colonización galesa en la Patagonia. 
Se analizó una serie de cartas escritas por los colonos galeses durante los primeros años de su establecimiento en el Chubut, extractando las
referencias a la cordillera de los Andes, a fin de averiguar cómo la
percibían antes de conocerla. Las cartas analizadas son anteriores al viaje
de Musters (1869-70) quien describió las bondades de la región subandina del Chubut, información que se difundió rápidamente en la Colonia. Las fuentes consultadas ponen de manifiesto que, aunque invisible, la cordillera era percibida como mucho más cercana y accesible, o aún como un punto de referencia cotidiano.
Esta concepción errónea, sumada a los comentarios muy favorables que los aborígenes hacían del área cordillerana, acicateó desde el comienzo de la colonización los deseos de los galeses de acceder a esa región. Empero, sucesivos intentos en ese sentido fueron demostrando la verdadera distancia a la que se situaban los Andes, que demoraron veinte años en ser alcanzados.

Los pequeños archipiélagos del litoral chubutense son los únicos de la costa patagónica. La necesidad de preservar su riqueza natural determinó, en 2009, la creación de un Parque pionero en su tipo en el país, co-administrado por Parques Nacionales y la Provincia del Chubut y que abarca tierra firme, islas y aguas costeras1. El parque encierra también una rica historia. Su recortada costa ofreció reparo a todos los navegantes desde el siglo XVI, por lo que fue uno de los tramos costeros más frecuentados (Destefani 1989). Asimismo, la explotación comercial de la fauna costera y sus derivados atrajeron la presencia foránea en la zona. Los vestigios de factorías de faena de anfibios del siglo XIX existentes en las islas Leones y Tova están muy escasamente documentados, por lo que la investigación in situ es especialmente necesaria y atrayente.

In the turn of the 19th century Patagonia was hastily occupied by sheep on not always suitable lands. Widespread desertification is the major ecological consequence of this process developed at the expense of Native-Patagonians. To seafarers, Patagonia was in the inter-oceanic route and was a dangerous coast to be left behind as soon as possible. Nowadays, with very low demographic density, and despite some ecological mismanagement, the region still keeps an aura of pristine nature, enhanced by distance and legend. This chapter may seem incongruent in this volume, but it aims to place the readers in the wider scope of Patagonian geo-history, the human environment in which the research here presented was carried out.
