Measuring What Matters: Advancing Agricultural Greenhouse Gases Accounting in Egypt

Abstract

Agriculture is one of the most climate-sensitive sectors in Egypt and is central to national food security, employment, and economic stability. Climate change is already affecting agricultural systems through shifts in cropping seasons, increased frequency and intensity of extreme events such as heat stress, sand and dust storms, flooding, and through sea-level rise and saltwater intrusion in coastal zones. These impacts are exacerbated by water scarcity, groundwater over-abstraction, and ecosystem degradation. Accordingly, Egypt’s National Climate Change Strategy 2050 and its Updated Nationally Determined Contribution (NDC) identify agriculture, irrigation, and water resources as priority sectors for adaptation and resilience building. Agriculture is also a significant source of national greenhouse gas (GHG) emissions. National inventories submitted to the UNFCCC estimate that agriculture and AFOLU accounted for approximately 15–16% of Egypt’s total GHG emissions in 2005 and 2015, driven primarily by nitrous oxide (N₂O) and methane (CH₄) from soils and irrigated systems. However, most estimates rely on IPCC default emission factors due to the absence of country-specific data, introducing substantial uncertainty under Egypt’s arid, irrigated conditions. Country-specific emission factors are essential to improve inventory accuracy, support credible monitoring, reporting and verification (MRV), and guide effective mitigation planning. Field-based GHG measurements provide the empirical foundation for deriving these factors, understanding key emission drivers, validating models for national scaling, and assessing the effectiveness of climate-smart agricultural practices. A phased national measurement strategy; combining standardized protocols, representative field campaigns, and institutional integration into MRV systems; will enable Egypt to reduce uncertainty, strengthen policy decisions, and advance integrated adaptation and mitigation in the agricultural sector.
