We conducted a study in a cross-border region of Amazonia to analyze the future role of natural forests in producing wood products. French Guiana and the state of Amapa are sharing similar geographical properties. A predominant area of these two territories are dominated by undisturbed tropical forests. In both regions, over 70% of forest areas is under public ownership. Currently the forestry sector in both regions do not have a key role in local economies, with low legal wood production in French Guiana (75 000 m3) as well as in Amapa (around 120 000 m3). Although in Amapá there is a high level of illegality in the sector (85%). In French Guiana and Amapa, forestry activities might represent an economical opportunity to promote endogenous development. The forest sector, including private and public actors, will face strategic choices to respond to increasing demand in wood supply for the coming decades. Strategic choices, based on strong political decisions, include the volume of wood to be produced locally, type of actors involved (i.e. communities, private companies), type of production (timber vs fuelwood) and origin of wood (plantation vs natural forest). Based on a prospective approach, we identified various scenarios, for each region, to reach the wood supply by 2045. First, we interviewed key actors of the forestry sector to obtain the view from their perspective. Second we selected the key variables to construct the scenarios and validated the resulting scenarios through a discussion with all actors. The scenarios identified in French Guiana had the implementation of tree plantation with local species as alternative to natural forest management, while in Amapa they focused on forest management associated with public policy and social factors. These scenarios are providing a framework of discussions that could help actors to focus on long term and to imagine the likely impact of current policy choices on the socioeconomy and conservation of natural forests.

The enzymatic reactions are very important for food. They are responsíble for the formation of highly desirable cornpound, but can cause disorders and undesirable consequences. The physiological behaviour of vegetables and fruits is already known, so that most of its deterioration changes in flavour, colour and nutritional value are caused by enzymes of the Oxidoreductases group, mainly peroxidases (PER) and polyphenol oxidase (PPO); The degradation of pectic polysaccharides involves two important enzymatic processed whose action is due to pectin methytesterase (PME) and po/ygalacturonase (PG) enzymes which affect the consistency and texture of fruit during ripening and postharvest handling. Pineapp/e is a tropical fruit very appreciated by consumers, but its physical-chemical and biochemical composition varies according to the time and place of production, and maturity stage. In order to optimize the extraction process of enzymes PER, PPO, PME and PG from pineapple pulp (ev. Peróla) the methodology of response surface was used (STATISTICA 7.0) to study the effect of pH (from 4.0 to 8.0) and NaCI concentration (from 0.0 to 2.0 M) of lhe buffer solulion used in lhe extraction of lhe enzymes. The results showed that the best conditions for enzymes extraction were 1.0 M NaCl, pH 6.0 for PER (4752.9 UI g), 1.0 M NaCI and pH 3.5 for PME (5.8 UI g), 2.0 M NaCI and pH 7.4 for PG (0,000034 Ulg.h·l) and 2.0 M NaCI and pH 4.0 for PPO (81.6 UI g). |
