The International Network of Black Soils: towards the Symposium

  1. 1. Yuxin Tong, GSP secretariat International Network of Black Soils
  2. 2. U S, Mollisols Argentina, Mollisols China, Isohumisols Russian and Ukraine, ChernozemCanada, Chernozem Black soils are high in soil organic carbon
  3. 3. Black soils constitute an important source of food for many countries and for the world in general, and are often recognized as inherently productive and fertile soils. 16.8 16.6 3.4 2.7 1.7 1.4 42.6 0 5 10 15 20 25 30 35 40 45 China United States of America Argentina Russian Ukraine Canada total Maize + Wheat + Rice + Soybeans Percentageoftheworld o The black soils in northeast China account for 1/3 of China’s commodity grain and 1/5 of China’s total grain. o Black soils in the United States accounts for 21% of the country’s territory. o The total area of black soils accounts for 52.6% of arable lands in the Russian. o Black soils in Argentina account for 32% of the territory.
  4. 4. Their significant soil organic carbon (SOC) content makes them sensitive as potential sinks and sources of greenhouse gases. Isohumisols, Songnen Plain. Northeast China Water erosion Wind erosion Decrease in Soil DepthSOC dynamics in Heilongjiang Province
  5. 5. Mollisols, Illinois, USA Where does the C go? In the atmosphere? How much of it? Soil organic matter decreased by 35.6-52.5% in Argentina. The amount of SOC in Russia and Ukraine have declined by 40%. Decrease in Soil Depth
  6. 6.  Black soils remain very sensitive to anthropogenic intervention. They are prone to severe degradation such as loss of SOC, but also: Guiqing Han; Ivan Vasenev; Miguel Taboada Loss of stable aggregates Salinization or sodification Soil compaction Soil nutrient unbalance Soil biodiversity losses Anthropogenic soil acidity
  7. 7. • Considering the great importance of black soils and their risk of severe degradation, it has become crucial to promote their conservation and sustainable use, • And to unlock their potential in the longer term to support food security while protecting the environment and mitigating climate change. On the basis of recommendation of the FAO’s Global Soil Partnership (GSP) on the UN’s Sustainable Development Goals (SDG) and the discussions and decisions from the Global Symposium of Soil Organic Carbon, the International Network of Black Soil (INBS) has been launched in Rome on 21th of March 2017.
  8. 8. Launch of INBS Mr. Guiqing Han, Heilongjiang Academy of Agricultural Sciences, China Side event: Launch of the International Network of Black Soils (INBS) Ms. Skye Wills, United States Department of Agriculture (USDA), USA Mr. Miguel Taboada, INTA, Argentina Mr. Ivan Vasenev, Timiryazev Academy, Russian Federation
  9. 9. INBS initiative was submitted by China China has 1.03 million km2 black soils China expressed their will to cooperate with black soil countries towards sustainable soil management for food security and climate change mitigation.
  10. 10. Definition of black soils • The preliminary definition of black soils under the International Network of Black Soils is: • Black soils are defined as Chernozems, Kastanozems and Phaeozems based on the World Reference Base (WRB) and Mollisols by the US Soil Taxonomy. Soil types Soil classification INBS Chernozems WRB Kastanozems WRB Phaeozems WRB Mollisols US Soil Taxonomy National black soil types Chernozems Russian classification Isohumisols China classification Chernozemic Canada classification Chernozems Ukraine classification
  11. 11. Black soil distribution in the world based on the WRB, includes Chernozems, Kastanozems and Phaeozems.
  12. 12. Mollisols under US Taxonomy
  13. 13. Objectives Provide a platform for black soil countries to discuss common issues and develop governance guidelines related to the conservation and sustainable management of black soils Develop a report on the global status, current production and challenges in black soils Foster collaboration among these countries towards promoting the sustainable use and management of black soils and identify relevant research gaps Serve as a platform for incorporating real local challenges for knowledge sharing and technical cooperation on black soils management
  14. 14. How will it work? • The network is established under the framework of the Global Soil Partnership (GSP). • Countries with black soils, through their national soil partners, are invited to join this network under clear terms of reference. • The ITPS of the GSP will provide the scientific and technical advice needed. 23 countries have joined the INBS: Armenia, Austria, Argentina, Brazil, Bolivia, Bulgaria, Canada, China, Indonesia, Kyrgystan, Malaysia, Moldova, Mongolia, Mozambique, Nigeria, Romania, Russian, Slovakia, Syria, Turkey, Ukraine, Uruguay, and USA.
  15. 15. Top 20 countries by area of black soil in the world WRB 2034596 1831664 926192 807037 744126 629199 436554 402804 243158 78657 65019 62276 60283 53475 45521 34524 30997 30718 29635 27381 0 500000 1000000 1500000 2000000 2500000 Chernozems + Kastanozems + Phaeozems (km2)

  17. 17. Global Symposium on Black Soils The International Symposium on Black Soils & the 1st Plenary of International Network of Black Soils (ISBS18) will take place in Harbin on 10 - 12 September 2018. The Symposium will discuss and compile the information available in the Concept note and the Framework of INBS. The Symposium will consolidate future cooperation between the members of the INBS, and action plans for the sustainable development of black soils with a focus on soil organic carbon, soil nutrients, soil erosion and soil health.
  18. 18. Thank You for Your Attention • You are all welcome to the Global Symposium on Black Soils in Harbin. • For the benefit of this black treasure of agriculture.
