Brochure, flyer, fact-sheetThe Global Livestock Environmental Assessment Model (GLEAM)
Quantifying options for low greenhouse gas emissions along livestock supply chains
2024Also available in:
No results found.The FAO Global Livestock Environmental Assessment Model (GLEAM) is a modelling framework that simulates the interactions between livestock production activities and the environment. By quantifying production and the use of natural resources in the livestock sector, GLEAM serves as a crucial tool for policymakers to assess the environmental impacts of livestock supply chains and to identify adaptation and mitigation interventions. This document summarizes and presents highlights and pbjectives of the project "GLEAM-X: web application to support thesustainable transformation towards low carbon livestock", implemented by FAO and founded by the Federal Ministry of Food and Agriculture of Germany, -
ArticleA comprehensive quantification of global nitrous oxide sources and sinks

No results found.Nitrous oxide (N2O), like carbon dioxide, is a long-lived greenhouse gas that accumulates in the atmosphere. Over the past 150 years, increasing atmospheric N2O concentrations have contributed to stratospheric ozone depletion1 and climate change2, with the current rate of increase estimated at 2 per cent per decade. Existing national inventories do not provide a full picture of N2O emissions, owing to their omission of natural sources and limitations in methodology for attributing anthropogenic sources. Here we present a global N2O inventory that incorporates both natural and anthropogenic sources and accounts for the interaction between nitrogen additions and the biochemical processes that control N2O emissions. We use bottom-up (inventory, statistical extrapolation of flux measurements, process based land and ocean modelling) and top-down (atmospheric inversion) approaches to provide a comprehensive quantification of global N2O sources and sinks resulting from 21 natural and human sectors between 1980 and 2016. Global N2O emissions were 17.0 (minimum–maximum estimates: 12.2–23.5) teragrams of nitrogen per year (bottom-up) and 16.9 (15.9–17.7) teragrams of nitrogen per year (top-down) between 2007 and 2016. Global human-induced emissions, which are dominated by nitrogen additions to croplands, increased by 30% over the past four decades to 7.3 (4.2–11.4) teragrams of nitrogen per year. This increase was mainly responsible for the growth in the atmospheric burden. Our findings point to growing N2O emissions in emerging economies—particularly Brazil, China and India. Analysis of process-based model estimates reveals an emerging N2O–climate feedback resulting from interactions between nitrogen additions and climate change. The recent growth in N2O emissions exceeds some of the highest projected emission scenarios3,4, underscoring the urgency to mitigate N2O emissions. -
Book (stand-alone)Analysis and Systematization on Intended Nationally Determined Contributions (INDC) in Latin America and Caribbean (LAC) countries based on the United Nations Framework Convention on Climate Change 2018
Also available in:
The twenty-second session of the Conference of the Parties (COP 22), the twelfth session of the Conference of the Parties serving as the meeting of the Parties to the Kyoto Protocol (CMP 12), and the first session of the Conference of the Parties serving as the meeting of the Parties to the Paris Agreement (CMA 1), were held in Bab Ighli, Marrakech, Morocco, from 7-18 November 2016. The Conference showed how the world is making progress for the implementation of the Paris Agreement, and how the constructive spirit of multilateral cooperation on climate change continues. Governments have set until 2018 to complete the Paris Agreement application standards, in order to ensure trust, cooperation and success in the upcoming years and decades. The agreement adopted at COP21 came into force on November 4, 2016, and, this way, countries have ratified their commitment to struggle to keep the increase in global temperature below 2 degrees centigrade and to achieve an economy free from greenhouse gas (GHG) emissions until the second half of this century. Within this context of challenges and considering the principles, provisions and structures of the United Nations Framework Convention on Climate Change (UNFCCC), the countries have filed documents on their Intended Nationally Determined Contributions (INDC). This analysis and systematization study examines the INDC documents from 32 Latin America and Caribbean (LAC) States.
