“…Rainfall interception and high stem flow in A. aculeata palms enable water infiltration and minimization of erosive processes (Corrêa et al 2016). Soil erosion in A. aculeata steep cultivation systems could be further prevented by implementing narrow-base terraces, a soil conservation technique to reduce surface runoff (Corrêa et al 2018).…”

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.

In order to contribute to the discussion on how forest development interacts with hydrological processes related to rainfall partitioning, we aimed to characterize the rainfall interception (RI), throughfall (Tf), stemflow (Sf), and net precipitation (NP) in three Cerrado areas at different stages of natural regeneration conduction: treatment 1 = area with 4 years without human intervention; treatment 2 = 10 years; and treatment 3 = 43 years. In all areas, three 400-m2 plots were established, in each of which 12 rain gauges and stemflow collectors were installed on all trees having Diameter at Breast High (DBH) > 5 cm. Data was recorded from December 2015 through November 2016. At treatment 1, Tf corresponded to 100% of gross precipitation (GP) in the micro-basin, while Sf corresponded to 0.01%, RI to 0%, and NP to 100% of GP. At treatment 2, Tf corresponded to 96% of GP, whereas Sf corresponded to 0.19%, RI to 4%, and NP to 96% of GP. At treatment 3, Tf corresponded to 87% of GP, while Sf corresponded to 1.15%, RI to 12%, and NP to 88%. The results revealed significant differences among the study areas. Both RI and Sf increased with advancing natural regeneration, while Tf and NP decreased. Data varied according to vegetation features, like the number and density of individuals and species in each plot, and according to characteristics related to weather and precipitation in the area.

Although the effects of land use changes on hydrological functioning are widely addressed, issues such as which components of the hydrological system are affected, how and on what time scales are still poorly understood. In this context, we evaluated whether forest restoration improves soil water conditions in a Cerrado area, and whether the combined effects of forest structure and hydrological variables influence soil attributes. For this, we monitored three areas in different stages of natural succession over seven months, and evaluated vegetation structure indicators, hydrological indicators and soil indicators. Vegetation structure variables were analyzed with Principal Components Analysis, and to evaluate the direct and indirect effects among the variables we used structural equations modelling. Each successional stage differed in relation to forest structure, affecting the hydrological processes and causing the improvement of soil attributes with forest development. In the initial stage, throughfall was higher due to the more open vegetation, and the soil was more resistant to penetration. With the development of the vegetation, stemflow and interception also increased. As a result of the structural and hydrological changes, the model indicated that soil moisture was influenced directly by throughfall and stemflow, as well as by soil resistance to penetration and infiltration rates, and indirectly by forest structure, which influenced these variables, except infiltration rates. These results suggest that hydrological variables can be good indicators of forest restoration monitoring, providing a direct link to changes in soil conditions.
