The study area is in the western Brazilian Amazon and is the Brazilian site of the Alternatives to Slash and Burn Agriculture (ASB) Programme. Firstly, the area's land use systems are described and entry points for agricultural intensification strategies are suggested. Secondly, the relative scarcity of land and labour is examined. Third, there is a presentation of evaluations of pairs of land-use system alternatives (traditional systems versus proposed more intensive alternatives), regarding adaptability, agronomic sustainability and broader environmental impacts, as well as tradeoffs between intensification and adaptability, plant biodiversity and carbon stocks. Finally the constraints involved in promoting successful intensification are outlined. |

This study aimed to develop and assess the physicoche-mical, sensory parameters, and shelf life estimation of multicomponent snack bars based on tapioca flour, Brazil nut, and açaí or cupuassu pulp. The physicochemical composition of açaí- and cupuassu-flavored snack bars had, respectively, 0.92 and 0.99% ash, 19.22 and 17.02% lipids, 3.02 and 3.03% protein, 1.06 and 1.69% fiber, and 448 and 436 kcal/100 g energy value. The shear stress test showed the consumer needs to bite more strongly to break the açaí-flavored bar. The opposite was observed in the hardness test, in which the bite compression force during mastication was greater for the cupuassu-flavored bar. The bars had water activity below 0.6, which deno-tes microbiological stability. The sensory analysis ranked the bars between ?liked slightly? and ?liked very much,? which was confirmed by the acceptability index above 75% for all attributes assessed. According to the results a significant increase in water activity over storage was observed suggest the packaging used in the tests did not present a satisfactory barrier to water vapor permeability. Only water activity was used to estimate shelf life, which was determined as 58 days and 49 days for the açaí- and cupuassu-flavored bars, respectively. Thus, the snack bars represent an alternative for athletes as well as individuals with celiac disease since they are gluten free |
