Title: Developing National Baseline GHG Emissions and Analyzing Mitigation Potentials for Agriculture and Forestry Using an Advanced National GHG Inventory Software System
Abstract: National greenhouse gas (GHG) inventories are compiled by governments for all sectors, including agriculture and forestry, and provide historical emissions data for assessing Nationally Appropriate Mitigation Actions (NAMAs). National inventory guidelines have been developed by the Intergovernmental Panel on Climate Change (IPCC), and the Agriculture and Land Use National Greenhouse Gas Inventory (ALU) software is an advanced system applying the IPCC inventory methods, along with functionality to assess GHG mitigation potentials. Two GHG mitigation case studies are provided for rice (Oryza sativa L.) management in the Philippines and livestock and manure management in South Africa. The Philippines example demonstrates that managing rice straw by burning the residues will decrease GHG emissions, relative to the current practice of leaving some rice straw on the field. Rice straw is a substrate that enhances methane emissions when the soil is flooded, and it is a source of nitrogen leading to soil nitrous oxide emissions. However, this option may not be a NAMA because retaining some residue in the field is important for longer-term sustainability of the soil for crop production, as well as the negative effects of burning residues on air quality and human health. For South Africa, enteric methane emissions can be reduced with feed additives in ruminant diets that are managed in confined operations. In addition, GHG emissions from manure management can be reduced with the more widespread use of digesters. The ALU software provides a framework to quantitatively assess mitigation options in a country and inform policy decisions about NAMAs.
