The international debate on real estate financialization has focused on cities located in “developed” economies. Researchers have found an increasing penetration of financial logics in the production of the city and an expansion of financial innovations on real estate financing. This work aims to discuss with this literature in order to place the Argentine case in perspective through certain indicators, while briefly retrieve the current state of the art. The central hypothesis is that Argentina followed a trajectory of relative disconnection of the international financial system between 2002 and 2015, with consequences in the urban production, which must be nevertheless understood within the framework of a global process of unequal variegated financialization.

One of the main consequences of gentrification is the displacement of poor and vulnerable residents. In the present investigation, we work in a comparative analysis of two resistance movements in the Ecuadorian cities of Quito and Cuenca to understand the processes of organization and protest against different types of displacements generated in historical and patrimonial centers. In both cases, a favorable opportunity structure is evident; strengths and weaknesses respect to the mobilization of resource, but there are important difficulties in the construction of identity and interpretive frameworks. As a result, such movements are effective in resisting direct movements and the chain of movements, but unable to avoid the pressure of displacement and exclusive displacement.

This work aims to explain the origins and evolution of tourism as a sociological and economic phenomenon in Galicia from the beginning of the 19th century. It identifies its phases, its impulse factors -in particular the role played by the extension of the first railway lines by Galicia and towards Galicia-, its modalities and the tourist geography that was drawn during this century.

Investigations on a detailed scale in the field of applied geography are highly conditioned by the availability of sources. Regardless of the area, the sources used to compile official statistics are rapidly changing, frequently interrupting the continuity of previous research, complicating detailed analysis at an intra-urban level. In this paper, alternative sources and a new methodological approach are explored. Socio-demographic studies from territorial perspectives are used to analyze two decisive and discrete processes and features of our cities: demographic and residential social deprivation. With our methodology, the spatial patterns of the deprived population are estimated on an intra-urban scale, incorporating observable and available information on buildings and the surrounding environment. After an approach at the level of the district, deprivation indexes are downscaled to the level of the building. A simple adaptation of this methodology may be exported to other cities.

El treball es focalitza sobre la interpretació de la Gran Recessió a partir d’alguns dels postulats provinents de l’economia clàssica i, en concret, de les teories de D. Ricardo, K. Marx i el complement de J.A. Schumpeter. Hom defensa la importància d’analitzar la crisi a partir d’indicadors que, generalment, es tenen poc en consideració per part de l’economia convencional: la naturalesa endògena de les crisis, l’evolució de la taxa de benefici i l’observació de la tendència a la productivitat del capital.The work focuses on the interpretation of the Great Recession from some assumptions from classical economics and, in particular, the theories of D. Ricardo, K. Marx and complement J.A. Schumpeter. It defends the importance of analyzing the crisis based on indicators that are generally considered to have little of conventional economics: the endogenous nature of the crisis, the evolution of the rate of profit and observation the trend in capital productivity.

It is known that the high-rise, private real estate exploitation in pericentral Santiago, Chile creates exclusionary social stratification. However, newer questions arises about the actions, motivations and expectations of the various intermediary agents that participate in this residential market, an ample range of supply/demand facilitators and financiers. The evidence collected here not only confirms the exclusion of the low and middle-low strata from Santiago’ pericentre, namely those without enough economic capacity or cultural capital to afford the new residence supplied, but also the stratification of the middle class between micro investors, privileged residents, and vulnerable residents.

After decades of low levels of out-migration, internal and international out-flows have increased in the same Spanish areas that experienced large population losses due to migration during most of the XXth century. But, unlike previous periods, the current migrants are highly educated and are moving out of urban areas. Castile and León is a clear example of this dynamic: it is the region with the largest proportion of young adults living outside their region of birth, a trend driven by the highly educated groups.

Nowadays the megaproject growth is a central characteristic of the capital accumulation global spaces. The key actors are the transnational corporations, which influence the States to set their projects. In this context, this paper analyzes, from a critical approach, the growth of the agro-industrial megaprojects of the forestry sector in the agrarian space of Uruguay, which occurred at the beginning of the 21st century, as part of the agribusiness model in the framework of the current phase of global capitalism. Therefore, I systematized the megaprojects principal characteristics, origin, territorial expansion, and impact in local communities. Finally, I conclude that the State is subordinated to the transnational capital domain, because almost 70% of the space and the 84% of the exportation belong to three transnational corporations.

La precipitación máxima probable (PMP) es la base para la estimación de la creciente máxima probable, con la cual se dimensionan y revisan hidrológicamente las grandes obras hidráulicas. Existen dos grupos de métodos para estimar la PMP: meteorológicos y estadísticos. Los primeros son más confiables, pero requieren muchos datos que, por lo general, no están disponibles. Los métodos estadísticos son mucho más simples y sólo utilizan valores de la precipitación máxima diaria (PMD) anual. El método clásico de este grupo es el de David M. Hershfield, expuesto en 1961. Posteriormente, en Inglaterra (NERC, 1975), se desarrolló otro método estadístico basado en la predicción de duración 24 horas y periodo de retorno (Tr) de cinco años, designado M5; este enfoque permite realizar predicciones con diversos Tr. Jónas Elíasson (Elíasson, 1997; Elíasson, 2000) generalizó el método M5 en una técnica regional que sólo requiere dos parámetros estadísticos: el M5 y el coeficiente de variación (Cv). En este estudio, se contrastan en 81 localidades del estado de Zacatecas, México, los resultados del método M5 generalizado (MM5G) contra los del método de Hershfield, previamente calculados con base en los datos de PMD. El MM5G se aplicó utilizando los valores puntuales de M5 y Cv disponibles. Los resultados orientan a recomendar el MM5G para estimar predicciones de PMD con Tr menores de 100 años en sitios sin datos dentro del estado de Zacatecas, México. También se recomienda para estimaciones de la PMP puntual de duración 24 horas, recordando que tal método subestima menos de 16.4% con respecto al resultado del método de Hershfield, cuando Cv es menor de 0.251 y sobreestima, del orden de un 38.0%, cuando Cv excede a 0.386.

Chihuahua es un estado árido que cuenta con pocas fuentes de agua superficial y utiliza para el riego principalmente fuentes de agua subterránea, cuyo volumen extraído tiene tendencia creciente. El acuífero Cuauhtémoc se ha explotado por varias décadas, en particular para el suministro de agua en la agricultura, y registra extracciones de volúmenes de agua mayores a la recarga, lo que ha generado sobreexplotación, con notables abatimientos de los niveles de bombeo. En las zonas de riego no ha sido posible cuantificar con regularidad la variación en superficies sembradas y regadas, así como el volumen empleado de agua. La estimación de estos volúmenes de agua se hizo a partir de la ubicación de los pozos usados para el riego y la evaluación de las superficies cultivadas. Para 2012 se ubicaron 1 317 unidades de riego abastecidas por 1 818 aprovechamientos de agua, cubriendo una superficie física de 55 555 hectáreas regadas, donde 92% del agua utilizada es subterránea; además, se cultivan de temporal poco más de 62 mil hectáreas; sin embargo, el reporte del SIAP para ese año fue de 47 792 hectáreas regadas, 7 763 menos que las detectadas. La superficie cultivada se concentra en dos cultivos: maíz (87.0%) y manzana (11.9%). Sin embargo, mediante la cuantificación de las superficies de cultivos en pie realizado para los años 2015 y 2016, se aprecia que la agricultura ha crecido por fuera de las áreas delimitadas en 2012, lo que implica un mayor consumo de agua subterránea.
