摘要

Global greenhouse gas (GHG) emissions have reached 53.0 Gt CO2eq in 2023, marking a 62% increase since 1990. Agriculture contributes a significant one-third of total anthropogenic GHG emissions. The land-based activities, enteric fermentation and supply chain processes primarily constitute the agri-food system’s emissions, which totalled 16 billion tonnes in 2020. Methane (CH4) emissions from enteric fermentation, rice cultivation and nitrous oxide (N2O) emissions owing to the use of nitrogenous fertilizers and soil reactions are of serious concern because of their higher global warming potential (GWP) than carbon dioxide (CO2) and a significant proportion of total GHG emissions from the agriculture sector. The sector’s reliance on fossil fuels, less efficient irrigation systems, synthetic fertilizers and monoculture practices exacerbates these emissions. Climate change issues are escalated through increased GHG emissions that pose challenges, affecting agricultural production through rising temperatures and shifting weather patterns. To minimize the impacts of climate change intensified from global warming and to meet the Paris Agreement’s goals of limiting rise in atmospheric temperature below 1.5 °C, agriculture must adopt best management practices (BMPs) that improve resource use efficiency (RUE), enhance carbon sequestration and lower carbon footprints (CF) in the lifecycle of agricultural produce. Precision agriculture (PA), regenerative agriculture (RA), conservation agriculture (CA), organic farming (OF), balanced fertilisation, limited irrigation, waste recycling, crop and livestock improvement through genome editing and the integration of renewable energy systems are essential for reducing the carbon footprints (CF) and achieving carbon credits (CCs) goals through enhanced carbon sequestration. The use of climate-smart technologies having the potential to turn GHG emission sources into sinks by enhanced soil organic carbon (SOC) sequestration deserves incentivisation for its promotion and widespread adoption., There is a need for robust standards and regulatory principles for the development of effective and transparent systems for measuring and verifying carbon credits (CCs). Awareness of citizens and suitable policy support for the adoption of sustainable farming practices and Research and Development (R&D) for advanced green technologies are essential for balancing the interplay between carbon emissions, climate actions and global food security.
