Brazil contains two-thirds of remaining Amazonian rainforests and is responsible for the most Amazon forest loss. Primary forest loss in the Brazilian Amazon has declined considerably since 2004 but secondary forest loss has never been quantified. We use a recently developed high-resolution land use/land cover dataset to track secondary forests in the Brazilian Amazon over 14 yr, providing the first estimates of secondary forest loss for the region. We find that secondary forest loss increased by (187 ± 48)% from 2008 to 2014. Moreover, the proportion of total forest loss accounted for by secondary forests rose from (37 ± 3)% in 2000 to (72 ± 5)% in 2014. The recent acceleration in secondary forests loss occurred across the entire region and was not driven simply by increasing secondary forest area but probably a conscious preferential shift towards clearance of a little-protected forest ecosystem (secondary forests). Our results suggest that secondary forests loss has eased deforestation pressure on primary forests. However, this has been at the expense of a lost carbon sequestration opportunity of 2.59?2.66 Pg C over our study period. |

tGlobal demand for organic produce has increased by ca. 20% annually as consumers express increas-ing concerns over pesticide residues in their food. Organic tomato farming under tropical conditions islimited, and studies of production for industrial processing are relatively rare. In this study, we aimed toevaluate a new biotechnological tool with the potential to accelerate the conversion from conventionalto organic industrial tomato production by combining the benefits of (i) the plant growth-promotingbacteria (PGPB) Herbaspirillum seropedicae and (ii) humates. This novel biofertilizer was first applied inplant growth substrate to stimulate seedling growth under greenhouse conditions; subsequently, it wasused as a foliar spray following the transplantation of greenhouse seedlings to field conditions. The ben-efits of vermicompost plus PGPB and humate were evident in both seedling growth and development.Fruit biomass increased significantly relative to control plants after changes in plant metabolism duringearly growth stages. After transplantation to the field, foliar spraying of PGPB and humates enhancednitrate uptake and nitrate reductase activity; it also stimulated the secondary metabolic phenylalanineammonia lyase pathway. This new generation of biological products based on vermicompost, solubleorganic matter and selected beneficial microorganisms provides opportunities for effectively increasingbiological inputs to sustainable food, fiber and energy production. |
