Conversion of cropland to grassland. Author(s): MADARI, B. E. 1. Description of the practice. 2. Range of applicability. 3. Impacts on soil organic carbon stocks. 4. Other benefits of the practice. 5. Potential drawbacks to the practice. 6. Recommendations befor... ... Repository: BDPA Publication year: 2021
Exploring the role of deforestation and cropland expansion in driving a fire-transition in the Brazilian Amazon. Author(s): FERREIRA, J. N. The Brazilian Amazonian Forest is undergoing significant changes in land use and land cover in the last few decades. This land-use transition, besides climate change, may be responsible for the fire r... ... Repository: BDPA Publication year: 2022
Forest carbon emissions from cropland expansion in the Brazilian Cerrado biome. Author(s): VICTORIA, D. de C.; BOLFE, E. L. Abstract. Land use, land use change, and forestry accounted for two-thirds of Brazil?s greenhouse gas emissions profile in 2005. Amazon deforestation has declined by more than 80% over the past decade... ...

Cropland area estimates using Modis NDVI time series in the state of Mato Grosso, Brazil. Author(s): VICTORIA, D. de C.; COUTINHO, A. C. The objective of this work was to evaluate a simple, semi‑automated methodology for mapping cropland areas in the state of Mato Grosso, Brazil. A Fourier transform was applied over a time series... ... Repository: BDPA Publication year: 2012
Mapping Fractional Cropland Distribution in Mato Grosso, Brazil Using Time Series MODIS Enhanced Vegetation Index and Landsat Thematic Mapper Data. Author(s): VICTORIA, D. de C. Mapping cropland distribution over large areas has attracted great attention in recent years, however, traditional pixel-based classification approaches produce high uncertainty in cropland area stati... ...

Reevaluating suitability estimates based on dynamics of cropland expansion in the Brazilian Amazon. Author(s): VICTORIA, D. de C.; BOLFE, E. L. Agricultural suitability maps are a key input for land use zoning and projections of cropland expansion. Suitability assessments typically consider edaphic conditions, climate, crop characteristics, a... ... Repository: BDPA Publication year: 2016
From forest to cropland and pasture systems: a critical review of soil organic carbon stocks changes in Amazonia. Author(s): BALBINO, L. C. Abstract - The impact of deforestation on soil organic carbon (SOC) stocks is important in the context of climate change and agricultural soil use. Trends of SOC stock changes after agroecosystem esta... ... Repository: BDPA Publication year: 2015
Vegetation Fraction Images Derived from PROBA-V Data for Rapid Assessment of Annual Croplands in Brazil. Author(s): SANO, E. E. Abstract: This paper presents a new method for rapid assessment of the extent of annual croplands in Brazil. The proposed method applies a linear spectral mixing model (LSMM) to PROBA-V time series im... ... Repository: BDPA Publication year: 2020
Annual cropland mapping using data mining and OLI Landsat-8. Author(s): OLDONI, L. V.; CATTANI, C. E. V.; MERCANTE, E.; JOHANN, J. A.; ANTUNES, J. F. G.; ALMEIDA, L. ABSTRACT: In the state of Paraná, Brazil, there are no major changes in areas cultivated with annual crops, mainly due to environmental laws that do not allow expansions to new areas. There is a great... ... Repository: BDPA Publication year: 2019
Organic matter composition in density fractions of Cerrado Ferralsols as revealed by CPMAS 13C NMR: Influence of pastureland, cropland and Integrated crop-livestock. Author(s): MACEDO, M. C. M. Repository: BDPA Publication year: 2014
