“…Oil palm (Elaeis guineensis Jacq.) stands out among oleaginous plants as the crop with the highest oil production per planted area (Sheil et al, 2009) and has become an alternative in public policies that use biofuels in the energy matrix (Kaewmai et al, 2012). It is a species typical of tropical climates originated in Tropical Africa with type-C 3 photosynthesis pathway and indicated for growth between 16° N and 15° S. Oil palm's productivity per planted area unit is high and the species is grown in 43 countries for a total of 16.4 million hectares worldwide (Food and Agriculture Organization of the United Nations, 2014).…”

Oil palm is considered the crop with the highest oil production per planted area unit. This condition has driven the Brazilian government to create the Sustainable Oil Palm Production Program. Since 2009, the agroenergy production chain has used oil palm as a viable and profitable crop to recover deforested areas in the Amazon. The aim of this study was to assess hydric conditions able to indicate the potential to expand oil palm crops in the state of Maranhão, even in the Legal Amazon. The climate database used (average and extreme temperature in degrees Celsius; rainfall values; relative humidity, and vapour-pressure deficit). Water deficit values were was obtained by comparing the potential evapotranspiration of oil palm (ETc) to actual rainfall (ER). Water balance was calculated based on available water capacity of 125 mm.month -1 . Evapotranspiration was obtained using the methodology according to the climate database available to calculate the evapotranspiration rate in an area planted with oil palm in this study. The water deficit values show no restriction in the soil water replacement between January and June. However, from July to December, the water deficit varies between 200 and 300 mm. The levels showed that, in the areas evaluated, oil palm crops will require irrigation. In this period, yield was estimated at 17 tons ha -1 when the water deficit was considered at 210 mm and 14 tons ha -1 for a deficit of 380 mm. This result reinforces that oil palm production may drop by more than 50% due to water deficits and the crop will greatly impact the economy and the environment if the irrigation strategy is adopted in the areas of Maranhão.

“…As a result, environmental impacts associated with palm oil production (Kaewmai et al 2012;Oosterveer 2014) have become a crucial issue in Southeast Asia, South America, and Africa (USAID 2009;Silalertruksa & Gheewala 2013). Several studies reveal that palm oil production contributes to a broad range of environmental problems, including global warming, biodiversity loss, eutrophication, acidification, and photochemical ozone formation.…”

“…Kaewmai et al (2012) indicated that non-CO 2 greenhouse gases have a relatively large share in the total global warming impact of oil palm production in Thailand. In this study, we therefore focus on non-CO 2 greenhouse gases, including methane (CH 4 ) emissions from waste management in the palm oil processes, and nitrous oxide (N 2 O) emissions when applying the nitrogen fertilizers in the oil palm plantations (Kaewmai et al 2012;Silalertruksa & Gheewala 2013).…”

“…Studies on the environmental impacts of palm oil production in relation to the RSPO certification in Thailand are limited. For instance, Patthanaissaranukool et al (2013) and Kaewmai et al (2012) focused on greenhouse gas emissions from palm oil mills but did not address the implications of RSPO. This may be related to RSPO criteria (RSPO P&C) not including specific requirements for reducing greenhouse gas emissions along the production chains of palm oil.…”
