Achieving Carbon Neutrality in Agriculture: Strategies for Mitigating Climate Change and Enhancing Sustainability

Abstract

Global warming and climate change have become a burning issue due to the hike in atmospheric concentrations of greenhouse gases (GHG). The rising GHG emissions over the past two centuries have caused significant changes in the global climate. Agriculture plays a prominant role in contributing to these emissions, yet its potential for reducing GHGs remains underutilized. Agriculture serves as both a source and a potential sink for GHGs, making it a critical area for intervention in climate change mitigation efforts. Current agricultural practices, however, face several limitations in addressing GHG emissions. Conventional farming often relies heavily on synthetic fertilizers, leading to substantial nitrous oxide emissions, while livestock farming remains a major source of methane. Additionally, unsustainable land-use practices, such as deforestation and soil degradation, further reduce the capacity of agricultural land to act as an effective carbon sink. These practices, combined with inefficient use of inputs like energy and water, contribute to agriculture's unsustainable carbon footprint. Carbon neutral farming addresses these gaps through a range of practices that maintain and enhance the carbon levels in soils, minimize GHG emission from crop and livestock production, and adoption of farming systems like mixed farming and agro-forestry that reduces emissions while promoting biodiversity. Efficient utilization of fertilizers, energy sources and other farm inputs is crucial, alongside efforts to revitalize soil health. Carbon neutral farming aims to balance the carbon emissions produced by farming activities with equivalent carbon removals or sequestration, resulting in a net-zero carbon footprint. Carbon neutral farming offers a promising pathway to transform agriculture into a sustainable, climate-resilient sector. By reducing emissions, enhancing sequestration, and offsetting remaining carbon footprints, this approach significantly contributes to global climate change mitigation efforts while also improving soil health, increasing biodiversity, and fostering economic viability in farming communities.
