ITEM 10. INBS – International Network of Black Soils - Yuxin Tong
of Black Soils
U S, Mollisols
Russia and Ukraine,
Black soils are soils that are black in colour
with a high soil organic carbon
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.
o The black soils in northeast China account for 103
million ha and produced 1/3 of China’s
commodity grain and 1/5 of China’s total grain.
o Black soils in United States accounts for 196
million ha, 36.9% of them are using for livestock
o Total area of black soils accounts for 52.6% of
arable lands in the Russian Federation.
o Black soils in Argentina account for 84 million ha
and most of them are used for agriculture.
• Black soils are extensively and
intensively farmed (cereal,
pasture, range and forage
• According to various estimates,
black soils lost over 20-50% of
SOC, and this trend is still
ongoing in most black soil
• The significant decrease of SOC
in black soils contributes to
climate change through
greenhouse gas emissions from
soils especially CO2.

Black soils remain very sensitive to anthropogenic intervention. They are prone
to severe degradation not only on SOC loss, but also on:

Loss of stable aggregates
Salinization or sodification
Soil nutrient unbalance
Soil biodiversity losses
Anthropogenic soil acidity
• Considering the great importance of black soils and their risk of severe
degradation, it has become crucial to promote their conservation and
• 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 in March 2017.
Launch of INBS
Members of INBS
1. Provide a platform for countries with black soils to discuss
common issues related to the conservation and sustainable
management of these soils;
2. Develop a report on the global status, current production and
challenges in black soils;
3. Foster collaboration among these countries towards promoting the
sustainable use and management of black soils and identify
relevant research gaps;
4. Serve as a platform to incorporate real local challenges for
knowledge sharing and technical cooperation on black soil
5. Develop governance guidelines aiming at improved black soils
protection and sustainable soil productivity;
Global Symposium on Black Soils
The International Symposium on Black Soils & First
Plenary of International Network of Black Soils (ISBS18)
have been held in Harbin on 10 - 12 September 2018.
1. The definition of black soils
2. Working plan of INBS
3. Harbin Communiqué
Second Plenary of INBS will hold in Moldova in October 2019
Output 1. The definition of black soils
Black soils, considered the food basket for many countries and for the world, and are often
recognized as inherently productive and fertile soils, are broadly defined under the
International Network of Black soils as soils having the following core characteristics:
• High organic carbon content as per the following:
>1.2% for cold and temperate regions
>0.6% for tropical and sub tropical regions
• Dark to black coloured surface horizons
• Thickness of dark to black soil surface horizons not less than 25 cm.
With the following complementary characteristics:
• A high base saturation >50%
• Strong aggregate stability
• High level of nutrient content
Output 2. Working plan
1. Complete a delineation of the areas identified as Black Soils according to the criteria
adopted at National level;
2. Perform a global assessment of black soils and publish it as a formal report of the Global
3. Black Soils Data streamline as part of a monitoring sub-component of the Global Soil
Information System (GLOSIS);
4. Support implementation the Voluntary Guidelines for Sustainable Soil Management in
the areas designated at National level as black soils;
5. Establish a capacity development programme on the management of black soils;
6. Prepare a policy brief on the importance of black soils and advocate for the
implementation of binding legislation for the full protection of these soils for future
7. Develop the “Best Available Practice” Knowledge Bank as part of INBS Information
Output 3. Harbin Communiqué
The members of the INBS have reached a consensus about a definition of black
soils and have signed on a black soil declaration “Harbin Communiqué” in order
to facilitate monitoring, mapping and sustainable management of black soils.
“Protect black soils, invest in the future”
Why global assessment of black
1. Where are the black soils in the world according to the
definition of INBS?
2. What are the status of black soils?
3. How the black soils contribute to global food security and
