Colombia has submitted two national communications (NCs 2001, 2010) to the United Nations Framework Convention on Climate Change (UNFCCC), providing information on greenhouse gas (GHG) inventories, and measures to mitigate and facilitate adequate adaptation to climate change, among other information. In 2015, Colombia also presented its First Biennial Update Report (BUR), including the REDD+ technical annex. In 2010 and 2012, GHG emissions from the Agriculture, Forestry and Other Land Use (AFOLU) sector contributed to respectively 58 % and 43% of the national GHG emissions. Since 2013, the United Nations Collaborative Programme on Reducing Emissions from Deforestation and Forest Degradation in Developing Countries (UN-REDD) and the Mitigation of Climate Change in Agriculture (MICCA) Programmes have provided support to Ecuador for the preparation and reporting of the national GHG inventory (NGHGI), AFOLU component, to the UNFCCC. This brief relates the implemented activities and fruitful collaboration that were fundamental in assisting Ecuador in successfully meeting its commitments to the UNFCCC reporting process for the Agriculture and LULUCF sectors.
