{{SignalTerm|type=DS|id=DS-00853|label=Agriculture — Agrifood systems Emissions}} Agriculture and agrifood systems are significant contributors to global greenhouse gas (GHG) emissions, influencing climate dynamics and environmental health. These emissions arise from a variety of agricultural activities including crop cultivation, livestock management, soil management, and food processing. Understanding and quantifying these emissions is essential for assessing their role in global climate change and for developing sustainable food production strategies.

Globally, food systems are estimated to be responsible for approximately one-third of anthropogenic greenhouse gas emissions. These emissions encompass a range of gases, primarily carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), expressed in terms of carbon dioxide equivalent (CO2e) to account for their differing global warming potentials. The complexity of agrifood systems and their emissions reflects the diversity of agricultural practices, geographic conditions, and supply chain processes.

Within the context of environmental monitoring, agriculture-related emissions are examined to inform scientific understanding of their magnitude, sources, and temporal trends. This knowledge supports broader environmental assessments and contributes to integrated frameworks that track human impacts on the climate system.

== Geographic / System Context ==
Agrifood systems emissions are not confined to a specific geographic region but are a global phenomenon linked to agricultural production and food supply chains worldwide. Emissions occur in diverse ecosystems ranging from tropical rainforests cleared for agriculture to temperate croplands and pastoral systems. Variability in agricultural practices, climate, soil types, and land use patterns across regions influences the emission profiles. Consequently, these emissions are studied at multiple spatial scales, from local farm operations to national inventories and global assessments.

== Monitoring and Measurement ==
Monitoring of agriculture and agrifood systems emissions involves a combination of direct measurement, modeling, and inventory approaches. Scientific institutions and agencies employ field measurements such as gas flux monitoring from soils and livestock, remote sensing technologies, and statistical data on agricultural inputs and outputs. Emission factors derived from empirical studies are applied to activity data in greenhouse gas inventories to estimate total emissions. International frameworks and protocols, including those supported by the [https://en.wikipedia.org/wiki/Intergovernmental_Panel_on_Climate_Change IPCC], provide standardized methodologies for reporting and comparing emissions across countries and sectors.

Within the SIGNAL system, this phenomenon is treated as a defined environmental signal whose boundaries and measurement conventions are described below.

== Signal Definition ==
The Agriculture — Agrifood Systems Emissions signal quantifies the total greenhouse gas emissions attributable to agricultural production and associated food system activities. This includes emissions of carbon dioxide, methane, and nitrous oxide expressed as carbon dioxide equivalent (CO2e). The signal encompasses emissions from crop cultivation, livestock enteric fermentation, manure management, soil amendments, rice paddies, and food processing stages directly linked to agricultural outputs.

== Boundary Conditions ==
Boundary inclusions for this signal cover all greenhouse gas emissions directly resulting from agricultural activities and agrifood system processes, including on-farm emissions and emissions from food processing related to agricultural products. Boundary exclusions include emissions from non-agricultural sectors such as transportation unrelated to food distribution, industrial activities outside agrifood processing, and land-use changes not directly connected to agriculture. Emissions from deforestation or land conversion for agriculture are typically accounted for separately under land-use change signals.

== Aggregation Semantics ==
Geographic aggregation of this signal can be conducted at multiple scales, including local, national, and global levels, reflecting the spatial distribution of agricultural activities. Temporal aggregation typically involves annual reporting periods to align with inventory and climate assessment cycles. Cross-signal aggregation may integrate this signal with related environmental signals such as land-use change emissions, forestry emissions, and energy sector emissions to provide comprehensive assessments of anthropogenic greenhouse gas sources. Aggregation notes emphasize the importance of consistent methodological frameworks to ensure comparability across regions and time periods.

== Observational Status ==
Current monitoring of agriculture and agrifood systems emissions relies on established greenhouse gas inventories and scientific studies that provide estimates of emissions and their drivers. Data availability varies by region and agricultural system, with ongoing efforts to improve measurement accuracy and temporal resolution. Future SIGNAL releases may incorporate enhanced datasets, refined emission factors, and improved integration with complementary environmental signals to support more detailed and dynamic assessments.
