The main feature of Indian society is that 63% of people live in rural areas, and 58% of the total population relies on agriculture for their livelihood. The growing demand for food and security is putting more pressure on land and climate. Agrarian countries like ours are highly vulnerable to climate conditions such as extreme rainfall, drought, pests, and diseases. Nonetheless, agricultural subsectors, such as livestock, biomass burning, and rice cultivation, emit high levels of greenhouse gases, which are also one of the leading contributors to global climate warming. Carbon dioxide (CO2), methane (CH4), and nitrous oxide (NO2) are the main culprits. heavily emitted from burning stubble, animals, and fertilizers. Agricultural activities alone account for 10–12% of global GHG emissions. After the Green Revolution, India became a food hub for the world, leading to the exploitation of natural resources. To deal with GHG emissions mitigation and adaption, the United Nations Framework Convention on Climate Change (UNFCCC) built the Paris Agreement in November 2015 to limit the world temperature to 1.50–20 °C. The existing literature suggests that policymakers, stakeholders, and communities evaluate current agricultural practices. This study analyses greenhouse gas point sources, which are toxic gases, and reviews current agriculture-related climate policy and best practices to reduce pollutants. Smart farming technologies are suggested.
