Modelling land sharing and land sparing relationship with rural population in the Cerrado.
Agricultural expansion and intensification enabled growth of food production but resulted in serious environmental changes. In light of that, debates concerning sustainability in agriculture arises on scientific literature. Land sharing and land sparing are two opposite models for framing agricultur...

Multi-temporal flood mapping and satellite altimetry used to evaluate the flood dynamics of the Bolivian Amazon wetlands.
The Bolivian Amazon wetlands are extensive floodplains distributed over the Mamore, Beni, Madre de Dios and Guapore Rivers. Located within the upper Madeira River Basin, the wetlands play important roles in regulating the biogeochemical processes and hydrological cycle of the region. In addition, th...

Reptile species persistence under climate change and direct human threats in north-western Argentina.
Protected areas have been established historically in residual places where the potential for extractive uses is low, implying that places at risk are usually under-protected. Argentina is no exception, with few protected areas established in productive regions that are prone to conversion. Here, us...

Microalgae-mediated bioremediation and valorization of cattle wastewater previously digested in a hybrid anaerobic reactor using a photobioreactor: comparison between batch and continuous operation.
Scenedesmus obliquus (ACOI 204/07) microalgae were cultivated in cattle wastewater in vertical alveolar flat panel photobioreactors, operated in batch and continuous mode, after previous digestion in a hybrid anaerobic reactor. In batch operation, removal efficiencies ranges of 65 to 70% of COD, 98 ...

Biofertilizer replace urea as a source of nitrogen for sugarcane production.
In this study, different nitrogen doses (0, 16, 48, 64, 80, and 96 kg ha−1 ) from two sources, biofertilizer (from anaerobic digestion of cattle wastewater) and urea, were applied to cultivate two sugarcane varieties (RB 867515 and SP 803280). °Brix values higher than 21% were obtained with appli...

Improving drought management in the Brazilian semiarid through crop forecasting.
In this paper, we evaluated the performance of the model AquaCrop for crop yield forecasting in the Brazilian semiarid (BSA) using meteorological observation and Eta model seasonal climate forecasts as input data. The study area is characterized by low rainfall that is poorly distributed throughout ...

Potencial do Cadastro Ambiental Rural (CAR) no controle do desmatamento em assentamentos no município de Novo Repartimento (PA).
Ao avaliar a dinâmica do desmatamento em 15% dos assentamentos federais do Estado do Pará, durante cinco anos, detectou-se haver proporcionalmente mais desmatamentos no interior dos assentamentos do que na área que os circunscreve. Assim, tem-se o Cadastro Ambiental Rural (CAR) como uma contribui...

Improving the use of ground-based radar rainfall data for monitoring and predicting floods in the iguaçu river basin.
This study investigates the efficiency of correcting radar rainfall estimates using a stochastic error model in the upper Iguaçu river basin in Southern Brazil for improving streamflow simulations. The 2-Dimensional Satellite Rainfall Error Model (SREM2D) is adopted here and modified to account for...
