    Soils help to combat and adapt to climate change by playing a key role in the carbon cycle 2015
    Healthy soils provide the largest store of terrestrial carbon. When managed sustainably, soils can play an important role in climate change mitigation by storing carbon (carbon sequestration) and decreasing greenhouse gas emissions in the atmosphere. Conversely, if soils are managed poorly or cultivated through unsustainable agricultural practices, soil carbon can be released into the atmosphere in the form of carbon dioxide (CO2), which can contribute to climate change. The steady conversion of grassland and forestland to cropland and grazing lands over the past several centuries has resulted in historic losses of soil carbon worldwide. However, by restoring degraded soils and adopting soil conservation practices, there is major potential to decrease the emission of greenhouse gases from agriculture, enhance carbon sequestration and build resilience to climate change.

    The Proceedings of the Global Symposium on Soil Organic Carbon 2017 (GSOC17) presents the abstracts of all scientific presentations held during the GSOC17. 103 oral presentations and 35 poster presentations built the core of this event triggering fruitful discussions on the state-of-science in measuring, preserving and enhancing soil organic carbon in different soils of the world. The GSOC17 took place from 21 to 23 March at FAO Headquarters and was structured in three themes: Theme 1: Monitorin g, mapping, measuring, reporting and verification (MRV) of SOC Theme 2: Maintaining and/or increasing SOC stocks for climate change mitigation and adaptation Theme 3 - Managing SOC in soils with high SOC - peatlands, permafrost, and black soils; in grasslands, and livestock production systems; and in dryland soils

    Agriculture can play an important role in climate change mitigation while contributing to increased food security and reductions in rural poverty. The Ex-Ante Carbon-balance Tool (EX-ACT) can estimate the mitigation potential of rural development projects generated from changes in farming systems and land use. The study presents and discusses the EX-ACT analysis performed on the World Bankfinanced Land Husbandry, Water Harvesting and Hillside Irrigation Project of the Government of Rwanda. Estim ates of the impact of project activities on greenhouse gas emissions and carbon sequestration demonstrate that the implementation of the LWH project will provide additional environmental benefits by helping to mitigate climate change. Thus it reflects possible synergies between mitigation and rural development goals through a watershed approach.
