ABSTRACT
In Sub-Saharan Africa, national greenhouse gas (GHG) inventories are computed with non-country specific Emission Factors (EF) of the Intergovernmental Panel on Climate Change (IPCC) Tier I approach. An alternative is Tier II or Tier III approach, which is country-specific using detailed animal performance and feed characteristics data and more accurate EF for developing Nationally Appropriate Mitigation Actions (NAMAs) and Low Emission Development Strategies (LEDS).This study sought to provide improved EF with data from a typical African livestock system sampled in Nandi County in Kenya. The EF were computed from methane production based on animal performance measurements using a sample of 487cows in 127 households across 36 villages spread over three major agro-ecological zones (AEZs). The cows were monitored for a period of one years. The mean EF estimate was50.6kg CH4/head/year for dairy cows (>2yrs), and was 23.4% higher than the IPCC Tier I estimates for unspecified African adult cattle. The dry matter digestibility (DMD) of feeds across the AEZs and seasons (60.0 – 68.4%) were not different and but the daily methane production (DMP) across the AEZs and seasons were significantly different (p
