Abstract: Centuries of colonization of the Atlantic Forest biome in Brazil have led its native vegetation cover to be reduced to only 11.7%. On the other hand, regional land changes have fostered natural forest regeneration, since the 1960s, in the region of Paraíba Valley. A fieldwork survey in rural properties was conducted in three municipalities (n = 90, thirty in each municipality), to assess how forest transition is affected by the region´s socioeconomic development and biophysical dimensions of the landscape. To select the municipalities among thirty-four, we applied the modified Thompson Tau technique to detect outlier values for three selected variables: Natural forest cover, eucalyptus plantation cover, and municipal revenue. The outliers were dropped from consideration and the municipality with the maximum value for each variable was selected. Based on the survey and GIS analysis using land-cover maps, topography, and hydrology variables, we concluded that the diminished land-use pressure in the Paraíba Valley, a response to the regional economic development (e.g., increasing labor demand in urban areas pushing rural migration), resulted in the increase of the Atlantic forest cover. Interestingly enough, a counter-migration of people moving to rural areas as a newly valued amenity has the potential to reshape the rural landscape with positive outcomes to the Atlantic forest cover. |

Abstract:The quality of grains and flour can be influenced by genetics, crop management, and environment. The objective of this study was to evaluate the technological quality of wheat grains and flour influenced by the interaction among genotype, nitrogen (N) fertilization and weather conditions in different regions of wheat crop adaptation in southern Brazil, aiming to support farmers and the bakery industry sector in their decision-making processes. The experiment was carried out in three environments (Londrina in rainfed and irrigated conditions; and Ponta Grossa in rainfed) in a randomized block design with a 10 × 2 factorial scheme. Ten wheat genotypes (BRS Sanhaço, BRS Graúna, BRS Gaivota, BRS Gralha-Azul, TBIO Sinuelo, TBIO Mestre, TBIO Sossego, TBIO Sintonia, TBIO Toruk, and Quartzo) and two N rates (40 and 120 kg ha-1) were assessed. The following technological quality analyses were performed in grains or flour: hectoliter weight, thousand-kernel weight, falling number, grain protein concentration, experimental flour extraction (i.e. flour yield), wet gluten concentration, and alveography. Increasing N rates from 40 to 120 kg ha-1 enhanced the concentrations of grain protein and wet gluten. However, it did not influence dough gluten strength and the commercial classification of the flour. Nitrogen fertilization also influenced the flour yield, dough tenacity and elasticity index, depending on the genotype × environment interaction. Environments with higher temperatures favored the flour yield and wet gluten concentration, while lower temperatures increased thousand-kernel weight and falling number. Water deficit increased the dough extensibility and grain protein concentration, whereas higher water availability favored the falling number, dough tenacity, and tenacity/extensibility ratio. Therefore, these outcomes are important drivers for farmers when choosing specific wheat genotypes for the environmental conditions of their farms, when they intend to meet the industrial requirements of mills and food companies that use wheat flour.
