    Beyond property: Rural politics and land-use change in the Colombian sugarcane landscape

    Full text link
    Analysing the sugarcane landscape in the flat valley of the Cauca River (Colombia) reveals that agricultural industrialization in the region required the concentration of land use by regional industrialists and the corresponding exclusion of landowners and poor peasants from territorial decision-making processes. The analytical lens used in this article, based on the use and control over land and land-based natural commons, allows for the characterization of three periods in a non-linear process of articulation and dispute between poor peasant and capitalist agents in the expansion of the sugarcane monoculture during the 20th century. The different constellations of social agents, governmental nexus, and capital enclosures have enacted through mechanisms that, beyond concentrating land property, have managed to deprive rural ethnic communities from their cultural and environmental heritage, traditional economies, and possible futures.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/151270/1/joac12332_am.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/151270/2/joac12332.pd

    Medio siglo de cambios paisajísticos en la montaña mediterránea. Percepción y valoración social del paisaje en la alta Garrotxa (Girona)

    Rural depopulation and abandonment of farming activities have resulted in an intense transformation of the characteristic landscapes of Mediterranean mountains. A dynamic characterized by an intense process of expansion of forested cover in detriment to livestock and agricultural areas. This process, which produces effects such as biodiversity and cultural heritage loss and contributes to the spread of wildfires, can be mapped, quantified and described with high accuracy through the means of digital mapping, geographic information systems and landscape indexes. But what is the perception and valuation of these changes by the stakeholders involved in the management of these territories? This article attempts to answer this question in the protected area of Alta Garrotxa (Girona), where a strong correlation between landscape dynamics and their perception by the stakeholders is revealed. On the other hand, the valuation and future prospects produce diverse and often contradictory points of views that illustrate the existing difficulties to management.<br><br>El despoblamiento rural y el abandono de la actividad agraria han originado una intensa transformación de los paisajes característicos de las montañas mediterráneas. Una dinámica marcada por un intenso proceso de incremento de la superficie forestal en detrimento de las zonas dedicadas a la ganadería y a la agricultura. Este proceso, que repercute en aspectos tan variados como la pérdida de biodiversidad y patrimonio cultural o la proliferación de incendios forestales, puede ser cartografiado, cuantificado y caracterizado con una gran exactitud gracias a la cartografía digital, los sistemas de información geográfica y los índices de paisaje. ¿Pero cuál es la percepción y la valoración de estos cambios por parte de los agentes sociales involucrados en la gestión de estos territorios? En este artículo se intenta dar respuesta a esta pregunta en el espacio protegido del Alta Garrotxa (Girona), donde se pone de manifiesto una elevada coincidencia entre las dinámicas del paisaje y la percepción de estas dinámicas por parte de los agentes sociales. En cambio la valoración social de estos cambios y las perspectivas de futuro generan opiniones diversas y a menudo contradictorias que ilustran las dificultades de gestión existente
