“…Enzymes activities have been suggested as sensitive indicators of soil biological properties (Dick, 1997;Nannipieri, 1994). The literature assessed showed that natural habitats have the highest enzymes' activity followed by pasture, while sugarcane presented a low enzymes' activity (Cardoso et al, 2016;Brackin et al, 2013;Ye and Wright, 2010;Sant'Anna et al, 2009;Zou and Bashkin, 1998;Magarey et al, 1997).…”

Since the 1950s sugarcane production has grown rapidly from less than 0.5 billion tonnes in the late 50s to reach over 1.9 billion tonnes in 2012 on about 27 million hectares of agricultural land. This expansion has been boosted by the high demand for bioethanol promoted as a sustainable bioenergy source which accounted in 2010 for the biggest share of the global biofuel market. Despite its benefits, the scientific debate on sugar is growing especially that counterarguments are so many, including negative impacts on different interacting ecosystems and human well-being, e.g. bigger stress on land and water resources, environmental externalities on air, a harmful impact on the biodiversity and endemic species, negative environmental externalities, health, and socio-economic aspects. This paper provides a narrative systematic review (SR) of the impacts of sugarcane production on these different ecosystems employing the ecosystem services framework for its acceptance by policy-makers. The references included for the SR were 163 and results showed that the majority of the studies are from Brazil, Australia, South Africa and the USA (≈ 75% of the literature), most of them were from peer-reviewed journals (85%), and most of the case studies adopted a quantitative research approach (93%). The literature assessed showed that sugarcane, like all agro-systems, depends on the practices and techniques to transform negative impacts into positive externalities on ecosystems and human well-being. However, the literature studied failed to include the inter-linkage in sugarcane production impacts’ and therefore to evaluate the related ecosystem services with respect to the Millennium Ecosystem Assessment (MA) framework to account for existing trade-offs. Therefore, the findings are addressed to the scientific community and decision-maker for an intensification of interdisciplinary and integrated research based on the MA framework to cover all ecosystem services, for sustainable development of the sugarcane sector.

Limitations to the Potential of Transgenic Trifolium subterraneum L. Plants that Exude Phytase when Grown in Soils with a Range of Organic P Content

et al. 2005

Growth and P-nutrition of transgenic Trifolium subterraneum L. which express a chimeric fungal phytase gene (ex::phyA) was compared to azygous and wild-type controls in a range of soils that differed in organic P content. Shoot and root growth by plant lines were measured and effects of reducing the influence of soil microorganisms were investigated by pasteurising the soils. Plants that expressed phyA did not have better P-nutrition than control plants after 56 days growth, except in a soil that contained a large concentration of both total organic P and organic P that was amenable to hydrolysis by a plant-derived phytase. Pasteurisation had little effect on the relative P-nutrition of the various plant lines in any of the soils. Roots of transgenic plants that expressed ex::phyA were shorter than controls up to 21 days growth in a number of soils, which resulted in an initial greater P accumulation efficiency. However, greater P accumulation efficiency was only maintained in the soil where significant growth and P nutrition responses were also observed. Availability of inositol phosphates in soil is a major factor that limits the effectiveness of expressing fungal phytase genes in plants as a means to improve P-nutrition. Reducing the influence of rhizosphere microorganisms appeared to have little effect on the P-nutrition of plant lines, but the longer root system produced by control plants may have initially provided them with greater access to soil P resources. This research highlights the inherent difficulty in improving the P-nutrition of plants by the manipulation of single traits in isolation, but does provide some evidence that such approaches can be successful under certain edaphic conditions.
