Summary
This summary is machine-generated.Methane emissions from Egypt's livestock sector fluctuated between 1989-2021, with hotspots in delta regions. Cattle and buffalo contributed most, highlighting the need for accurate greenhouse gas (GHG) data for climate mitigation.
Area Of Science
- Environmental Science
- Agricultural Science
- Climate Change Research
Background
- Livestock farming is a significant source of greenhouse gas (GHG) emissions globally.
- Understanding spatial and temporal methane (CH4) emission variations is crucial for targeted climate change mitigation.
- Egypt's livestock sector, encompassing enteric fermentation and manure management, requires detailed emission analysis.
Purpose Of The Study
- To investigate methane emissions from Egypt's livestock sector from 1989 to 2021.
- To analyze spatial and temporal variations in methane emissions at the governorate level.
- To identify emission hotspots and influencing factors within the Egyptian livestock sector.
Main Methods
- Employed Intergovernmental Panel on Climate Change (IPCC) guidelines and emission factors for methane estimation.
- Calculated emissions for various livestock categories including cattle, buffalo, sheep, goats, and poultry.
- Utilized statistical analysis, including cluster analysis, to examine emission patterns and regional variations.
Main Results
- Methane emissions showed fluctuating patterns, with declines in some governorates (e.g., Kafr El-Sheikh) and increases in others, driven by population dynamics.
- Emission hotspots were identified in Nile Delta governorates (Behera, Sharkia) and agriculturally significant regions (Menia, Suhag).
- Cattle and buffalo were the primary sources of methane emissions, despite sheep and goats having larger populations; manure management contributed minimally (5-6%).
Conclusions
- Methane emission changes were not strongly correlated with specific geographic or climatic boundaries.
- Accurate data collection and adherence to IPCC methodologies are vital for effective GHG emission assessment.
- Targeted mitigation strategies are essential to address climate change impacts within the livestock sector.
