“…Agricultural frontier expansion and land concentration in the Cerrado have historically been favoured by land grabbing, particularly what is known in Brazil as grilagem: the illegal appropriation of public land using false or forged ownership documents (Silva and Sauer 2022). These long-standing patterns of illegal appropriation and concentration have worsened since 2016 (and particularly after 2019), when the government adopted new legal and administrative measures that have been a driving force for land grabbing and the commodification and privatisation of land and natural resources (Sauer, forthcoming).…”

“…Narratives about economic opportunities and social imperatives (such as feeding the world) continue to be replicated and to constitute imaginaries of the Cerrado, reflected in the formal demarcation of Matopiba by the Brazilian government, which has sought to brand this space as an industrial agricultural territory. Some have also argued that the Cerrado (and the Matopiba region in particular) is consolidating its position as a 'sacrifice zone' that feeds the world while avoiding the advance of the agricultural frontier further into the Amazon, a territory that is under closer scrutiny and subject to more stringent environmental regulation (Silva and Sauer 2022).…”

Introduction: Reclaiming the Cerrado – A Territorial Account of a Disputed Frontier

As global agri-food systems come under increasing stress, debates on their future have become highly polarised, exposing fundamental differences in understandings and priorities: industrial production versus traditional rights; short-term yields versus longer-term sustainability; cheap versus healthy food. Brazil is at the core of these debates, with the Cerrado being centre stage since the soybean-powered Green Revolution. Accompanied by deforestation, soil degradation, and depletion of water resources, Brazil’s agricultural production frontier has now moved northwards into the Matopiba region. This issue of the IDS Bulletin explores the ongoing territorial transformation, considering the violent logics of extraction in frontier zones, the grabbing of nature, and the dynamics of resistance in local and international spheres. Exposing both the material and discursive appropriation experienced by the Cerrado, this issue profiles it as a key site of multi-scalar injustices against people and nature that need to be addressed by efforts to secure more just and sustainable agri-food systems.

Forest fires can profoundly impact the hydrological response of river basins, modifying vegetation characteristics and soil infiltration. This results in a significant increase in surface flow and channel runoff. In response to these effects, many researchers from different areas of earth sciences are committed to determining emergency measures to rehabilitate river basins, intending to restore their functions and minimize damage to soil resources. This study aims to analyze the mapping detection capacity of burned areas in a river basin in Brazil based on images acquired by AMAZÔNIA-1/WFI and the AQ1KM product. The effectiveness of the AMAZÔNIA-1 satellite in this regard is evaluated, given the importance of the subject and the relatively recent introduction of the satellite. The AQ1KM data were used to analyze statistical trends and spatial patterns in the area burned from 2003 to 2023. The U-Net architecture was used for training and classification of the burned area in AMAZÔNIA-1 images. An increasing trend in burned area was observed through the Mann–Kendall test map and Sen’s slope, with the months of the second semester showing a greater occurrence of burned areas. The NIR band was found to be the most sensitive spectral resource for detecting burned areas. The AMAZÔNIA-1 satellite demonstrated superior performance in estimating thematic accuracy, with a correlation of above 0.7 achieved in regression analyses using a 10 km grid cell resolution. The findings of this study have significant implications for the application of Brazilian remote sensing products in ecology, water resources, and river basin management and monitoring applications.
