Growing global trade with organic products has given rise to a debate on the environmental impacts during both production and transport. Environmental hotspots of organic orange juice produced by smallholders in Brazil, processed and imported to Denmark, were identified in a case study using a life cycle approach. Furthermore, small-scale organic orange production was compared with small-scale conventional and large-scale organic orange production in the case study area in Brazil. Transport was the main contributor (58%) to the global warming potential of organic orange juice from small-scale farmers imported to Denmark, followed by the farm stage (23%), especially the truck transport of fresh oranges in Brazil and of reconstituted orange juice in Europe. Non-renewable energy use per hectare was significantly lower on the organic small-scale farms than on the conventional, with a similar pattern for global warming potential and eutrophication. Including soil carbon sequestration in organic plantations widened the difference in global warming potential between organic and conventional. Organic small-scale farms had a higher crop diversity than conventional, which may have a positive effect on biodiversity along with the spontaneous vegetation between the organic orange trees and the absence of toxic pesticides. Comparing small-scale with large-scale organic orange production, crop diversity was higher on the small-scale farms, while global warming potential, eutrophication potential and the use of copper per hectare were significantly lower, indicating that environmental impacts from small-scale differ from large-scale organic farms.

Mangrove soils have unique properties, able to transform and sequester chemical compounds of biogeochemical and ecological importance, including heavy metals. The degeneration of mangrove soils shows the risk of releasing these metals to the environment. We search for improve the knowledge about how disturbance affects the metal fixation and microbial of mangrove soils. This study characterized a mangrove soil along the Graciosa River estuary (Bahia, Brazil), according to selected physical, chemical and microbiological properties. In 2002, soil was collected from an anthropic and from an adjacent natural site. Both sites were re-sampled in 2007, after a vegetal regeneration on the anthropic site. Significant differences between the natural and anthropic surface layers were observed for chemical and physical soil properties. In particular, heavy metals (Co, Cr, Cu, Zn, Ni, Mn and Fe) showed significant differences with depth and lower concentrations were found in the anthropic site, exception to Cd (moderately high). Between 2002 and 2007, the disturbed site showed a decrease for all observed metals, except for Ni. The data also suggest that microbial populations may be favored in the layers of the soil profile most influenced by high and low tides, C1 (0-20 cm) and C5 (99-125 cm). |
