Review of literature on drivers of GHG emissions from agriculture
| Research | Country/location | Greenhouse gas emissions | Findings |
|---|---|---|---|
| Cui et al. (2018) | Hebei province, China | Carbon emissions | Affluence, urbanization, agricultural population and mechanization increase carbon emissions |
| Long et al. (2018) | China | Carbon intensity | Population, GDP and urbanization have positive impacts |
| Li et al. (2014) | China | CO2 emissions | Population and affluence increase emissions |
| Parajuli et al. (2019) | 86 countries of different regions | CO2 emissions | Increase in agricultural land increases CO2 emissions |
| Lin and Xu (2018) | Provinces of China | Agricultural CO2 emissions | Population, GDP and urbanization have a positive effect, and energy efficiency has a negative effect |
| Xu and Lin (2017) | Provinces of China | Agricultural CO2 emissions | Population, GDP, energy intensity and urbanization have a positive effect |
| Hamilton and Turton (2002) | OECD countries | CO2 emissions | Energy intensity of agriculture increases CO2 emissions |
| Yan et al. (2017) | Selected European countries | GHG emissions | Energy intensity and carbon intensity increase emissions of GHGs |
| Maraseni et al. (2009) | Selected developing and developed countries | GHG emissions | Crop yield, mechanized irrigation and chemical fertilizer use increase emissions |
| West and Marland (2003) | Land samples | CO2 emissions | Increased crop yield and decreased land use can reduce emissions |
| Minami and Neue (1994) | Land samples | Methane emissions | Irrigation intensity affects methane emissions |
| Smith (2005) | Land samples | N2O emissions | Use of fertilizer can affect N2O emissions positively |
| Bhatia et al. (2013) | India | Methane emissions | Rice cultivation increases methane emissions |
| Neumann et al. (2014) | Bangladesh | Methane emissions | Groundwater irrigation can increase methane emissions |
| Johnson, Franzluebbers, Weyers, & Reicosky (2007) | Land samples | N2O emissions | Fertilizer choice and intensity increase N2O emissions |
| Selden and Song (1994) | OECD countries | Different GHGs | Population density has nonlinear effects on emissions |
| Lantz and Feng (2006) | Canada | CO2 emissions | Population has a nonlinear effect on CO2 emissions |
| Ali et al. (2017) | Pakistan | CO2 emissions | Fertilizer use and production of tractors affect CO2 emissions |
| Abbas, et al. (2020) | Pakistan | CO2 emissions | Total population increases emissions, rural population and agricultural land have an insignificant impact |
