La colonización dirigida, espontánea y estratégica, además de la permanente ampliación de la frontera agrícola para la extracción de recursos naturales, han determinado el uso y zonificación del espacio amazónico en los últimos 50 años. Las drásticas huellas socio-económicos, culturales y ambientales generadas por estos procesos han impactado negativamente la vida de los pueblos ancestrales y la naturaleza. Una consecuencia drástica es el cambio de la comprensión de la territorialidad en el interior de los territorios indígenas, y de la percepción que de aquel cambio tienen el Estado y los actores asentados en el entorno territorial comunitario. El presente estudio aborda el caso del pueblo waorani e inquiere cómo la ampliación de la frontera extractiva intensificaría los impactos negativos del proceso de desterritorialización en el Parque Nacional Yasuní, poniendo en mayor riesgo la integridad física y cultural de los de los pueblos que viven en aislamiento voluntario: Tagaeri y Oñamenane u otros de los cuales no se tiene referencia.   Abstract Targeted, spontaneous and strategic colonization, in addition to the permanent expansion of the agricultural frontier for the extraction of natural resources, has determined the use and zoning of the Amazonian space in the las 50 years. The drastic socioeconomic, cultural and environmental impacts generated by these processes have impated negatively the life of the ancestral peoples and nature. A drastic consequence is the change of the understanding of the territoriality in the interior of the indigenous territories, and the perception that the state and the actors settled in the community territorial environment have of that change. This study addresses the case of the Waorani people and inquires how the expansion of the extractive frontier would intensify the negative impacts of the process of decentralization in the Yasuní National Park, putting at greater risk the physical and cultural integrity of the peoples living in voluntary isolation: Tagaeri and Onamenane or others of which there is no reference.

Forest regrowth is key to achieve restoration commitments, but we need to better understand under what circumstances it takes place and how long secondary forests persist. We studied a recently colonized agricultural frontier in southern Mexico. We quantified the spatiotemporal dynamics of forest loss and regrowth and tested how temporal variation in climate, and spatial variation in land availability, land quality and accessibility affect forest disturbance, regrowth and secondary forest persistence. Marqués de Comillas consistently exhibits more forest loss than regrowth, resulting in a net decrease of 30% forest cover (1991-2016). Secondary forest cover remained relatively constant while secondary forest persistence increased, suggesting that farmers are moving away from shifting cultivation. Temporal variation in disturbance and regrowth were explained by the annual variation in the Oceanic El Niño index combined with dry season rainfall and key policy and market interventions.Across communities the availability of high-quality soil overrules the effects of land availability and accessibility, but that at the pixel-level all three factors contributed to explaining forest conservation and restoration. Communities with more high-quality soils were able to spare land for forest conservation, and had less secondary forest that persisted for longer. Old forest and secondary forests were better represented on low-quality lands and on communal land. Both old and secondary forest were less common close to the main road, where secondary forests were also less persistent. Forest conservation and restoration can be explained by a complex interplay of biophysical and social drivers across time, space and scale. We warrant that stimulating private land ownership may cause remaining forest patches to be lost and that conservation initiatives should benefit the whole community. Forest regrowth and secondary forest persistence competes with agricultural production and ensuring farmers can access restoration benefits is key to success.

This article presents an overview of the environmental history of the Brazilian Cerrado, its environmental characteristics and the processes related to the historical change in the landscapes of this endangered ecosystem. It highlights competing classifications of the Cerrado, the role of politics in establishing them, and the environmental consequences of such classifications. More than just describing an environment, classifying an ecosystem is a political process that involves complex socio-environmental interactions. The sources used points out the different attempts to get to know and "conquered" the Cerrado, bringing together interdisciplinary perspectives from a variety of actors and institutions. Historiographic challenges go beyond environmental descriptions in that the socio-environmental interactions that made up this unique ecosystem are equally complex. This paper’s conclusions reinforce the interdisciplinary role of environmental history in the study of ecosystems and the complex relationship between culture and nature.
