چکیده انگلیسی
This study aimed to estimate hazardous and greenhouse gas (GHG) emissions and associated environmental impacts from fuelwood burning and synthetic fertilizer application by tobacco growers in Pakistan during the cropping year of 2014-2015. Primary data regarding fuelwood and synthetic fertilizers consumption were collected through surveys and interviews with tobacco growers in the Khyber Pakhtunkhwa (KP) and Punjab provinces of Pakistan. Annual fuelwood consumption data (t dm/y) were converted into harvested biomass (m3) using a general wood density value of 0.65 t dm/m3. For annual GHG estimations, methodology outlined by the Intergovernmental Panel on Climate Change (IPCC) was applied. The results revealed that fuelwood consumption varies from region to region and amounted to 99,268 t dm and 152,721 m3 during the cropping year 2014-2015. GHG emissions from fuelwood burned by tobacco curing barns are estimated as 160,245 tCO2, 705 tCH4, and 4.74 tN2O in 2014-15. Moreover, consolidated GHG emissions from fuelwood burning in tobacco curing barns in terms of tonne CO2-equivalent using global warming potential for 100-year time horizon is estimated to be 176,564 tCO2e during 2014-15. Similarly, annual nitrogenous fertilizers and urea consumption and consequent N2O and CO2 emissions were 117,223 and 41,084 kg and 347 and 30 tCO2e emissions, respectively. Furthermore, consolidated GHG emissions from synthetic fertilizers consumption in tobacco growing regions are estimated to be 377 tCO2e in 2014-15. Fuelwood harvesting and synthetic fertilizers application by the under study tobacco curing industry is a major cause of GHG emissions and contributes about 0.00094% of the Pakistan's greenhouse gas emissions. The results of a life cycle impact assessment for different synthetic fertilizers applied to produce one kg of green tobacco revealed that NPK (nitrogen-phosphorus-potassium), ammonium nitrate, and urea production and application had the highest contributions to the abiotic depletion, acidification potential, eutrophication potential, and global warming potential impact categories. Therefore, it is imperative to take into account hazardous and GHG emissions mitigation strategies from fuelwood harvesting and synthetic fertilizers application by tobacco growers in Pakistan.
