“…Given the possible scale of activity that may develop, it is important to understand implications for soil and water sustainability (Cowie et al 2006;Payne 2010;Sochacki et al 2013). Although implications of reforestation have been considered in terms of water yield (Jackson et al 2005;GerbensLeenes et al 2009), water quality (Diaz-Chavez et al 2011) and soil carbon storage (Cowie et al 2006;Harper et al 2012), the impacts on soil water repellency have not been specifically considered, either in terms of ongoing site management in eucalypt plantations or as part of the sustainability criteria for bioenergy plantations (Scarlat and Dallemand 2011). This is despite the reported association of eucalypts with water repellency in plantation-grown Eucalyptus globulus in the Iberian Peninsula (Doerr et al 1998;Ferreira et al 2000;Rodríguez-Alleres and Benito 2011) and in natural forests in Australia (McGhie and Posner 1980;Crockford et al 1991;Prosser and Williams 1998;Harper et al 2000).…”

Abstract. There is an increasing interest in eucalypt reforestation for a range of purposes in Australia, including pulpwood production, carbon mitigation and catchment water management. The impacts of this reforestation on soil water repellency have not been examined despite eucalypts often being associated with water repellency and water repellency having impacts on water movement across and within soils. To investigate the role of eucalypt reforestation on water repellency, and interactions with soil properties, we examined 31 sites across the south-west of Western Australia with paired plots differing only in present land use (pasture v. plantation). The incidence and severity of water repellency increased in the 5-8 years following reforestation with Eucalyptus globulus. Despite this difference in water repellency, there were no differences in soil characteristics, including soil organic carbon content or composition, between pasture and plantation soils, suggesting induction by small amounts of hydrophobic compounds from the trees. The incidence of soil water repellency was generally greater on sandy-surfaced (<10% clay content) soils; however, for these soils 72% of the pasture sites and 31% of the plantation were not water repellent, and this was independent of measured soil properties. Computer modelling revealed marked differences in the layering and packing of waxes on kaolinite and quartz surfaces, indicating the importance of interfacial interactions in the development of soil water repellency. The implications of increased water repellency for the management of eucalyptus plantations are considered.

“…Sustainability of this kind of bioenergy requires minimizing this fossil participation and improving the performance of the water management in bioenergy activities . Biofuels from crops are comparatively more intensive in freshwater use than fossil fuels . For instance, average water consumption in the oil fuels supply‐chain (extraction and refining) is 0.19 m 3 /GJ, and 0.17 m 3 /GJ for synthetic fuels (gas to liquids or carbon to liquids) .…”

Mexico's government has introduced a Law on Climate Change that is unique worldwide; it establishes targets for greenhouse gases reductions at the same level of developed countries despite being an emerging country. This reform represents a crucial challenge for the electrical and transport sectors largely dependent on fossil energy since Mexico is the ninth-largest oil producer in the world. Local industry and academic sectors are called to lead the introduction of renewable energy sources, and particularly to enhance the share of energy from biomass in the local energy basket. Thus, this paper outlines the baseline on regulatory, energy, and carbon markets, and the scientifi c capacity to increase bioenergy utilization in Mexico. Furthermore, it opens a discussion about the steps forward with regard to sustainability and research needs, emphasizing some priorities and principles to develop a bioenergy system environmentally compatible in this country.

Moreover, the concerns due to biofuels production [3][4][5] and the fact that ethanol production is expected to grow in Brazil justify the research presented in this paper.…”

Sustainability has been considered essential for the future consumption of biofuels in large scale and, thus, assessing the impacts on water resources is one of the priorities. The aim of this study is to assess the potential impacts of sugarcane expansion both on the quality and on the quantity of water resources, but using a publicly available database and well‐established statistic procedures. The case studies were defined in São Paulo state, where the bulk of sugarcane production in Brazil is, and more specifically three regions where significant expansion recently occurred: Palmares Paulista, Pontal, and Ribeirão Preto. Time series of streamflows and precipitations (1974–2011) and water quality parameters (1989–2011) were evaluated using non‐parametric tests for detecting trends and abrupt changes. Quality parameters analyzed were concentrations of potassium, total phosphorus, nitrite, nitrate, ammoniacal nitrogen, total solids, dissolved oxygen, and biochemical oxygen demand. Sugarcane cropping data were correlated with streamflows and water quality parameters. Water quality parameters were analyzed vis‐à‐vis sugarcane production and population growth. Significant impacts due to sugarcane cropping were detected only in the case of the smallest basin. In the three studied regions a significant increasing trend of nitrogen and biochemical oxygen demand was observed, but these results can be explained either by sugarcane–ethanol production or by the discharge of sewage and industrial effluents without appropriate treatment. Based on data availability it was not possible to rigorously determine the contribution of large‐scale production of sugarcane cropping to both the quantity and the quality of water resources. © 2016 Society of Chemical Industry and John Wiley & Sons, Ltd
