New Generation Agronomy for Net-Zero Greenhouse Gas Emissions

Climate change is a reality which poses threats to agricultural production, food, and livelihood security. We must restrict the global average temperature rise to below 1.5°C in the coming four decades which can be achieved by mitigating greenhouse gas (GHG) emissions by 30-50%. Agriculture, specifically agronomy, plays a crucial role not only in reducing GHG emissions but also to sequester carbon for the long term and mitigating climate change. Climate-smart agronomic practices which consider sustainable production, adaptability to climate change vagaries and reduction of GHG emissions need to be promoted both in developed and developing countries. Site-specific technologies with national consideration and international acceptance are necessary to combat climate change. New generation agronomy, including fertilization through micro-irrigation, real-time nutrient management (sensor-based), innovative in-situ residue management, zero tillage in intensive cropping systems, beneficial microbial enrichment in the rhizosphere, nano-fertilizer and pesticide application, drone-based application of inputs and natural farming in high-value crops (cash crop) etc., could be viable options to achieve net-zero emissions.

We welcome manuscripts of cutting-edge technologies/innovations which could curtail emissions and help to achieve the net-zero GHGs from agriculture by 2070.
