Classes

Cropland

Represents a cropland land use.

class land_classes.cropland.Cropland(ef_country, transition_matrix_data, land_use_data, past_land_use_data, past_land_use=None, current_land_use=None)

Bases: landcover_lca.land_classes.landuse.LandUse

Represents a cropland land use.

Parameters:

ef_country (-) – The country for which the land use data is being analyzed.
transition_matrix_data (-) – An instance of TransitionMatrixData class containing data for transitions between different land use categories over time.
land_use_data (-) – Land use transition data for future scenarios.
past_land_use_data (-) – Data representing current or past land use scenarios.
past_land_use (-) – The past land use category. Defaults to None.
current_land_use (-) – The current/future land use category. Defaults to None.

- current_land_use

The current/future land use category.

Type:: str

- current_area

The current area of cropland.

Type:: float

- current_area_drained

The current area of cropland that is drained.

Type:: float

- burning_ch4_cropland: Calculates the methane (CH4) emissions resulting from the burning of cropland.

- burning_n2o_cropland: Calculates the nitrous oxide (N2O) emissions resulting from the burning of cropland.

burning_ch4_cropland()

Calculates the methane (CH4) emissions resulting from the burning of cropland. This method assesses CH4 emissions specifically from cropland areas where crop residues and other biomass are burnt, a practice that can significantly contribute to CH4 emissions.

The calculation involves two emission factors: one for the fuel burning in croplands (biomass combustion) and another emission factor (Gef) for CH4 emissions from cropland burning. These factors are sourced from a country-specific database, reflecting regional variations in agricultural practices and crop types.

The total CH4 emissions are estimated by multiplying the current area of cropland that is burnt, the emission factors for fuel burning, and the general emission factor for CH4. The result is converted into tonnes for easier reporting and comparison.

Returns:

The calculated CH4 emissions (in tonnes) from the burning of: cropland. The calculation considers the area of cropland burnt, the specific emission factor for fuel burning in croplands, and the general emission factor for CH4 emissions.

Return type:

float

Notes

ef_cropland_fuel_burning refers to the emission factor for the burning

of cropland fuels in terms of CH4. - ef_ch4_cropland_Gef is the general emission factor for CH4 emissions from cropland burning. - self.current_area represents the current area of cropland being analyzed. - self.land_use_data.cropland.share_burnt indicates the percentage of the cropland area that undergoes burning.

burning_n2o_cropland()

Calculates the nitrous oxide (N2O) emissions resulting from the burning of cropland. This method assesses N2O emissions specifically from cropland areas where crop residues and other biomass are burnt, a practice that can significantly contribute to N2O emissions.

The calculation involves two emission factors: one for the fuel burning in croplands (biomass combustion) and another emission factor (Gef) for N2O emissions from cropland burning. These factors are sourced from a country-specific database, reflecting regional variations in agricultural practices and crop types.

The total N2O emissions are estimated by multiplying the current area of cropland that is burnt, the emission factors for fuel burning, and the emission factor for N2O.
