Background The forest fragments of Stryphnodrendron adstringens have disappeared because of the high rate of Brazilian Savannah deforestation for commercial purposes, such as eucalypt, citrus, soy bean, and sugar cane crops that have been intensely cultivated on those areas [1]. Economically, S. adstringens is important for manufacture industries of paints and tanneries, but also is utilized fo...

A preliminary s~rvey was conducted to provide an esti~ate of the seventy of red rot (Glomerella tucumanensis) I~ vanous parts of the sugar industry. The incidence of this dIsea~e was greater in the higher altitude areas, with long growing cycles, and where crops were damaged by sesamia or eldana borers. The most severe case observed was 52% of stalks of NC0376 infected in a field at Kranskop. S...

But are subsidies really the problem? For some crops – most notably cotton and sugar – Northern subsidies clearly are a root cause of low international prices and unfair com...

Energy Poplar (Enhancing Poplar Traits for Energy Applications) is an EC Seventh Framework Programme project aimed at further improving poplar trees as an energy crop. The work is directed to understand and improve traits such as yield and wood properties coupled to Bioethanol production. The project also addresses environmental and economical sustainability questions. The final goal of ENERGYP...

This paper offers an integrated analysis of the forces shaping the emergence of the African slave trade over the early modern period. We focus our attention on two questions. First, why most of the increase in the demand for slaves during this period came exclusively from western Europeans.

Ethanol is mainly produced from sugar cane (Brazil) and corn or other cereals (US), but these sources induced criticisms as for social sustainability, being directly competitive with the food and feed chain. Therefore, a second generation concept was introduced for biofuels, by developing processes for their production from waste biomass or energy crops not competitive with agriculture. However...
