Spatiotemporal mapping of soybean plantations in Rondônia, Western Brazilian Amazon

Abstract: Although soybean production has been increasing in the state of Rondônia in the last decade, soybean planted area has been estimated indirectly using secondary datasets, which has limited understanding of its spatiotemporal distribution patterns. This study aimed to map and analyze spatial patterns of soybean expansion in Rondônia. We developed a classification technique based on Spectral Mixture Analysis (SMA) derived from Landsat imagery and Decision Tree Classification to detect and map soybean plantations … Show more

“…Rising global demand for palm oil for food and biofuels had stimulated the conversion of 2.3 million ha of peat swamp forest for oil palm plantations by 2010 on the Malay Peninsula, Borneo, and Sumatra (Koh, Miettinen, Liew, & Ghazoul, 2011). Biofuel crop plantations are likewise implicated of deforestation in the Amazon in South America, despite cattle farming and soy cultivated for animal feed accounting for over 80% of pasture expansion in the period 2005-2013 (Barona, Ramankutty, Hyman, & Coomes, 2010;da Costa, Matricardi, Pedlowski, Cochrane, & Fernandes, 2017;Gollnow, Hissa, Rufin, & Lakes, 2018;Pendrill, Persson, Godar, & Kastner, 2019). Modeling simulations with an increased global ethanol demand by 2030 predict sugarcane driving expansion of agriculture into the natural vegetation of the Cerrado and Amazon (van der Hilst, Verstegen, Woltjer, Smeets, & Faaij, 2018).…”

“…A área total para a mesorregião (Cerejeiras, Corumbiara, Chupinguaia) é de 1.097.402,95 ha, de acordo com arquivos vetoriais do Instituto Brasileiro de Geografia e Estatística (IBGE) (COSTA et al, 2017). Na classificação não supervisionada foi quantificado 990.820,25 ha de floresta no ano de 1990, já em 2017 foi quantificado 482.305,76 ha, correspondendo respectivamente a 90,28% e a 43,94%.…”

“…Meanwhile, depletion of timber resources in some regions (Eastern Pará, Mid-Northern Mato Grosso and Southeastern Rondônia) leads to an increase of agriculture-based land use in the Amazon, mainly the expansion of soybean cropping fields (Schneider et al, 2002;Veríssimo & Cochrane, 2003;Tritsch & Arvor, 2016;Costa et al, 2017) and pastures. Selective logging frontiers are followed by the expansion of agricultural activities.…”
