Agriculture is a significant contributor to global carbon dioxide (CO2) emissions, primarily through activities related to land use and management. The signal "{{SignalTerm|type=DS|id=DS-00855|label=Agriculture — All sectors without LULUCF Emissions}}" focuses on quantifying CO2 emissions from agricultural activities excluding those related to Land Use, Land-Use Change, and Forestry (LULUCF). This distinction is important for isolating emissions strictly attributable to agricultural production processes rather than changes in land cover or forest management.

Globally, food systems, including agriculture, are responsible for approximately one-third of anthropogenic greenhouse gas emissions, underscoring the relevance of monitoring this sector's emissions separately. Understanding these emissions is critical for assessing agriculture's role in climate dynamics and for informing environmental assessments and mitigation strategies.

This signal provides a structured approach to measure and analyze CO2 emissions from agriculture across all sectors, excluding LULUCF, within a comprehensive environmental monitoring framework.

== Geographic / System Context ==
The signal is not confined to a specific geographic region but encompasses global agricultural activities across diverse ecosystems and climates. Agricultural emissions arise from a variety of sources including crop cultivation, livestock production, soil management, and the use of fertilizers and machinery. These activities occur worldwide, spanning temperate, tropical, and arid zones, reflecting the broad spatial extent of agriculture as a human land use and economic sector.

== Monitoring and Measurement ==
Monitoring CO2 emissions from agriculture involves a combination of direct measurements, modeling, and inventory approaches. Scientific institutions and agencies often rely on national greenhouse gas inventories, remote sensing data, and process-based models to estimate emissions. These methods account for factors such as soil carbon changes, fertilizer application rates, livestock methane emissions, and energy use in farming operations. The integration of such data enables comprehensive assessments of agricultural emissions at various scales.

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

== Signal Definition ==
This signal measures the total carbon dioxide emissions attributable to all agricultural sectors excluding emissions linked to Land Use, Land-Use Change, and Forestry (LULUCF). It captures CO2 released from agricultural production processes such as soil cultivation, fertilizer application, livestock management, and on-farm energy consumption, while specifically excluding emissions or removals associated with changes in land cover or forestry activities.

== Boundary Conditions ==
Boundary inclusions encompass all CO2 emissions generated directly by agricultural activities across all sectors, excluding any emissions or carbon fluxes related to land use changes, deforestation, afforestation, or forest management. Boundary exclusions explicitly omit emissions from LULUCF activities, including carbon stock changes in forests and other land covers, as well as non-CO2 greenhouse gases such as methane and nitrous oxide that may also arise from agriculture but are outside the scope of this signal.

== Aggregation Semantics ==
Geographic aggregation for this signal is global and not limited to specific regions, reflecting the widespread nature of agricultural emissions. Temporal aggregation can vary depending on data availability but typically involves annual estimates to align with greenhouse gas inventory reporting cycles. Cross-signal aggregation may integrate these emissions with other environmental signals related to land use, forestry, and non-CO2 greenhouse gases to provide a comprehensive view of anthropogenic emissions from food systems. Aggregation notes emphasize the importance of consistent definitions and exclusion criteria to ensure comparability across datasets and time periods.

== Observational Status ==
Current monitoring relies on national and international greenhouse gas inventories, supplemented by scientific research and modeling efforts. Data quality and coverage vary by region and depend on reporting protocols and measurement capabilities. Future SIGNAL releases may incorporate improved spatial resolution, temporal frequency, and integration with related signals to enhance understanding of agricultural emissions dynamics and their environmental impacts.
