“…Other publication adding relevant information for crop management includes an evaluation of acrocomia's root system (Moreira et al 2019), studies of potential pests, e.g., Raoiella indica and Cyclocephala forsteri (Maia et al 2020;Souza et al 2020), a model to estimate bunches weight (Malaquias et al 2019), and the validation of a prototype for harvesting by mechanical vibration (Grupioni et al 2020). Carbon sequestration in cultivated acrocomia and potential carbon credit generation were assessed for the first time (Moreira et al 2020b). Socio-economic effects and human health impacts of acrocomia-based aviation biofuels contributed to the social dimension of sustainability studies (Wang et al 2019(Wang et al , 2020.…”

“…Estimations of the emission balance of A. aculeata in a timeframe of 30 years result in a negative value (more carbon sequestrated than emitted) ranging from -617 to -956 t CO 2 eq ha −1 (Evaristo et al 2018;Imaflora 2020). This suggests a potential advantage in comparison to the emission balance of African oil palm cultivation (Germer and Sauerborn (2008) estimated that the emission balance of African oil palm ranges from -136 to -1335 t CO 2 eq ha −1 depending on crop management and land-use change) (Evaristo et al 2018;Moreira et al 2020b).…”

Acrocomia spp., a genus of wild-growing palms in the neotropics, is rapidly gaining interest as a promising multipurpose crop. Diverse products can be derived from various components of the palm, the oils being of highest interest. Acrocomia shows similar oil yield and fatty acid composition to the African oil palm (Elaeis guineensis). It is, however, able to cope with a wider range of environmental conditions, including temporary water scarcity and lower temperatures, thus potentially a more sustainable alternative to its tropical counterpart. Acrocomia’s research history is recent compared to other traditional crops and thus knowledge gaps, uncertainty, and challenges need to be addressed. This review attempts to assess the acrocomia’s preparedness for cultivation by highlighting the state-of-the-art in research and identifying research gaps. Based on a systematic literature search following a value web approach, it (a) provides a comprehensive overview of research topics, (b) shows the development of publication activities over time and the drivers of this development, and (c) compiles main findings to assess the acrocomia’s preparedness for commercial cultivation. Our results confirm its multipurpose characteristic as a potential feedstock for manifold sectors. Research has continued to increase over the last decade, especially on A. aculeata and is driven by the interest in bioenergy. Increasing knowledge on botany has contributed to understanding the genetic diversity and genus-specific biology. This has enabled applied research on seed germination and propagation toward domestication and initial plantation activities, mostly in Brazil. Main research gaps are associated with genotype–environment interaction, planting material, crop management, and sustainable cropping systems. Overall, we conclude that acrocomia is at an early phase of development as an alternative and multipurpose crop and its up-scaling requires the integration of sustainability strategies tailored to location-based social-ecological conditions.

“…The use of perennial oleaginous species is a promising alternative because they enable the productive incorporation of marginal areas for agriculture, through a more conservationist soil management approach, using fewer agrochemicals and achieving a greater carbon sequestration capacity (Silva Moreira et al, 2020). In this context, the potential of Acrocomia totai Mart.…”

This work aimed to explore the potential value of the Acrocomia totai defatted kernel meal as an alternative feed ingredient for Nile tilapia (Oreochromis niloticus) diet. In vitro assays were conducted simulating tilapia digestion. Soybean meal was included as a reference and two phytase doses were assayed. After running the gastrointestinal simulations, amino acids bioavailability from soybean meal with phytase addition was higher than in the other treatments. However, when expressed on a crude protein content basis, the relative performance of the treatments with A. totai improved.The protein composition of the raw materials affected their performance because of globulins and specific amino acids such as arginine, lysine and histidine. A higher relative contribution of these last in Acrocomia kernel protein determined their lower compared performance. Phosphorus bioavailability from Acrocomia, expressed on a dry matter basis, was the highest, but increments resulting from phytase addition, expressed on a phytic acid basis, were not significantly different between raw materials. Therefore, no specific affinity between phytase and the raw materials' phytic acid was evidenced. This study demonstrated that A. totai kernel meal has potential as a protein source in aquafeed but also it has limitations: it is a big phytic phosphorus source that is only available with phytase addition.

“…While coffee is an international and consolidated agricultural commodity (Lewin et al, 2004), macauba is a relatively new crop in farming systems around the world (Motoike et al, 2013), experimenting with an expanding crop area where the fruit is rich in oils that can be used in several industrial sectors. A recent study highlighted the potential of the macauba as regards carbon sequestration (Moreira et al, 2020), and cultured agroforestry systems can mitigate change and maintain areas favorable to coffee production (Gomes et al, 2020), minimizing the effects of climate change and generating potential income from the carbon credits market. The benefits of macaubas on the microclimate can also be relevant to the AMF community because it is not yet understood how these microorganisms respond to global climate change (Bennett & Classen, 2020).…”

“…in agroforestry system has been highlighted in the literature (Dias et al, 2011;Viana et al, 2011;Moreira et al, 2018). This is a native palm from tropical regions in the American continent (Dransfield et al, 2008), which produces rich oils from fruit, and can be used in the biodiesel industry (Dias et al, 2011) and in biokerosene for aviation (Boeing et al, 2013), as well exhibit recognized potential for use in land reclamation (Mota et al, 2011) and in carbon credits projects (Moreira et al, 2020).…”

Coffee crop in Brazil is typically grown as a monoculture. However, we hypothesized that agroforestry system is favorable association for arbuscular mycorrhizal fungi (AMF), affecting its community structure and potentially impacting crop productivity and agroecosystem health. This study evaluated how the microclimate, soil depth, macauba field spacing and distance between coffee plants and palms affect the structure of the AMF community. The structure of the AMF community was influenced by the soil depth, microclimate features, soil moisture, maximum air temperature, and photosynthetically active radiation (PAR). The distance at which coffee-macauba influences ecological diversity indices of AMF, and higher diversity are related to the proximity between plants. AMF diversity (Richness and Shannon) in the agroforestry system exceeded that observed in the full-sun coffee in the 0-20 soil depth layer. Our results showed that the microclimate, soil depth, plant density, and distance between coffee from macauba affected the AMF community structure.
