burning_co2_wetland()

Calculates the carbon dioxide (CO2) emissions resulting from the burning of wetland vegetation and organic matter. This method focuses on CO2 emissions due to the combustion of wetland biomass, which can occur in various scenarios, such as land management practices or wildfires.

These factors are sourced from a country-specific database, reflecting regional variations in wetland composition and burning practices.

The total CO2 emissions are estimated by multiplying the total combined area of the wetland, the proportion of the wetland that is burnt, and the product of the two emission factors.

Returns:

The calculated CO2 emissions (in tonnes) from the burning of wetlands.

The calculation is based on the combined wetland area, the share of wetlands burnt, and the specific emission factors for wetland fuel burning and general CO2 emissions.

Return type:

float

burning_ch4_wetland()

Calculates the methane (CH4) emissions resulting from the burning of wetland vegetation and organic matter. This method assesses CH4 emissions, a potent greenhouse gas, released during the combustion of wetland biomass, which can occur due to natural fires, agricultural burning, or other human activities.

The calculation involves two primary emission factors: one for the combustion of wetland fuels (biomass) and another representing the emission factor (Gef) for CH4 emissions specifically from wetland burning. These emission factors are sourced from a country-specific database to account for regional differences in wetland burning characteristics and fuel types.

The total CH4 emissions are estimated by multiplying the combined wetland area, the proportion of wetland that is burnt, and the product of the two emission factors.

Returns:

The calculated CH4 emissions (in tonnes) from the burning of wetlands.

This method incorporates two emission factors: one for the combustion of wetland fuels (biomass) and another for the emission factor (Gef) specific to N2O emissions from wetland burning. These emission factors are obtained from a country-specific database, which accounts for variations in wetland types and burning practices across different regions.

The total N2O emissions are estimated by multiplying the combined area of the wetland, the proportion of the wetland that is burnt, and the product of the two emission factors.

Returns:

The calculated N2O emissions (in tonnes) from the burning of wetlands.
