“…The conversion of natural forests to monoculture has a number of direct and indirect effects (Savilaakso et al ., ), generally resulting in the loss of both terrestrial species, such as mammals (Azhar et al ., ), birds (Azhar et al ., ), reptiles (Glor et al ., ; Correa et al ., ), arthropods (Turner and Foster, ), butterflies (Koh and Wilcove, ), ants (Fayle et al ., ) and termites (Vaessen et al , 2011), as well as the aquatic ones that inhabit streams, such as macroinvertebrates (Mercer et al ., ; Cunha et al ., ) and fish (Nahum and Santos, ). However, most of the studies with aquatic fauna are essentially descriptive, leaving gaps in our knowledge of the real impact on most aquatic organisms, such as the fish that inhabit streams in oil palm plantations.…”

Effects of Oil Palm Plantations on the Habitat Structure and Biota of Streams in Eastern Amazon

et al. 2016

Oil palm plantations have expanded around the world, increasing concern about its pressure on deforestation rates and the homogenization of the landscape. In this context, the present study aimed to evaluate the impact of oil palm plantations on the physical characteristics of streams in Amazonia and their effects on Heteroptera, Odonata and Fish assemblages. A total of 23 streams were sampled, eight within fragments of primary forest, while 15 were in oil palm plantations. Data were collected on characteristics of the channel morphology, substrate, hydraulics, instream cover for aquatic organisms, riparian vegetation, human impacts and woody debris. Instream cover and proximity of human impacts were the variables that had the greatest effects on the physical structure of the streams, showing variation between streams of forest in pristine areas and oil palm plantations. Of the analyzed parameters, substrate, instream cover and woody debris influence the richness of Heteroptera, Odonata and Fish. The impact of oil palm plantations on local streams depended on the size of the plantations, and they cannot be considered an adequate substitute for lost habitats in efforts to preserve the physical habitat of Amazonian streams. Any type of conversion of the natural forest can have direct or indirect impacts on the dynamics and structure of these environments, with potentially negative consequences for their biodiversity. The maintenance of an adequate buffer zone of native riparian vegetation adjacent to the streams that flow through the plantations recommended, because this appears to be the principal factor determining the physical conditions of these streams.

Cassava, rice, and beans remain an important source of local smallholder production and consumption (Nahum and Santos 2013). This study area also falls within the Belém Center of Endemism, a highly fragmented and fire-prone region that ranks among the most deforested and ecologically threatened eco-regions of Amazônia (Almeida and Vieira 2010).…”

Global models of biophysical suitability for oil palm consistently rank Brazil as having the greatest potential for expansion, with estimates as high as 238 Mha of suitable lands. In 2010, Brazil launched the Sustainable Palm Oil Production Program (SPOPP) to incentivize oil palm development without deforestation on as much as 30 Mha. Here we examine oil palm expansion before and after the SPOPP's launch. In Pará, the major oil palm producing state in Brazil, we analyze the extent and change in oil palm cultivation from 2006−2014 using satellite imagery, ground-truthed verification, site-based interviews, and rural environmental (land) registration data. Between 2006−2014, oil palm area (≥9 ha) expanded >200% to ∼219 000 ha. Of the ∼148 000 ha of oil palm developed, ∼91% converted pasturelands while ∼8% replaced natural vegetation, including intact and secondary forests. Although >80% of all oil palm parcels rest <0.5 km from intact forests, direct conversion of intact forests declined from ∼4% pre-SPOPP (2006−2010) to <1% post-SPOPP (2010−2014).Despite low and declining deforestation rates associated with oil palm expansion in Pará, our results also show a low area of oil palm development overall compared with reported land suitability. To explore potential contributing factors, we conducted semi-structured interviews with researchers, company representatives, and government officials involved in the sector to characterize the perceived factors influencing oil palm development and the role of agro-ecological suitability mapping among them. Interviews indicated that: (1) individual effects of suitability mapping efforts to encourage oil palm expansion on cleared areas, i.e. without deforestation, cannot be disentangled from pre-existing public and private deforestation reduction initiatives; and, (2) socio-economic constraints, e.g. high relative production costs and limited familiarity with this crop, appear to partially explain the major discrepancy between estimated potential suitable areas with realized oil palm development.

“…Mostrando que a expansão da dendeicultura no nordeste paraense promove mudanças no uso da terra e, por conseguinte, nas formas de trabalho. Formam-se territórios do dendê possibilitados por políticas estatais associadas aos interesses empresariais (Nahum, Santos, 2013). Os territórios-rede (Haesbaert, 2004) construídos pela Biopalma, Archer Daniels Midland (ADM), Agropalma, Denpasa, Dentaua, Marborges, Yossan, GuanfengGroup, Belém Bioenergia Brasil (BBB)/PETROBRAS Biocombustível/GALP e Palmasa articulam-se por meio de um conjunto de rodovias, pontes e portos, emergindo a região do dendê na Amazônia paraense, cujo cenário em junho de 2015 é representado na Figura 1.…”

Interpretamos geograficamente a dendeicultura na Amazônia paraense. Diferentemente das perspectivas que focam sua rentabilidade, partimos do território usado no sentido de aprofundar o debate. Concebemos essa atividade como evento que assinala um novo tempo na dinâmica territorial do espaço agrário no nordeste paraense. Desde então é possível identificarmos um período geográfico do dendê tornado possível por um conjunto de ações políticas estatais e empresariais que permitiram a formação de territórios da palma e aprofundaram a concentração de terra nas mãos de poucas empresas. Nos lugares sob a influência da dinâmica desse agronegócio vemos a subordinação do território usado às empresas surgir no horizonte traços de um campo sem camponês.
