Project 665 - Sustainable use of black soil critical zone

Projet du PICG - réunion 2019

3rd Workshop on Black Soil Research

  • 25-27 October 2019, Chendu, China


The third workshop of Global Black Soil Critical Zone Geo-ecological Survey is planned to held from 25 to 27 October 2019.

The conference themes of the third workshop of IGCP 665 / BASGES in 2019 are as follow:

1. Multi-scale remote sensing and monitoring of global black soil critical zone;

2. Spectral and Multi-scale geochemical survey of global black soil critical zone;

3. Northeast China black soil Critical zone observatory construction and comparative study with global black soil critical zone;

4. To study integrated modeling system of global black soil critical zone based on multidisciplinary collaboration;

5. To study the carbon cycle of black soil and its relationship with climate change and human activities;

6. Microbial research of global black soil critical zone;

7. Establish an international platform for extensive communication and cooperation, data and information sharing in global black soil critical zone.

Through geochemistry, satellite remote sensing, soil spectral method, to carry out the remote sensing geological, geochemical survey, hydrogeology and basic geological survey, comprehensively promote the sky ground soil in the integration of the global black soil critical zone geological ecological investigation and monitoring. Achieve the global black soil critical zone geochemical and remote sensing geological mapping. Strengthen the construction of the northeast China black soil zone long-term observation, and network with the United States critical zone observatory, formation of global black soil critical zone dynamic monitoring network. Meanwhile, based on the mapping and monitoring results, global black soil critical zone soil-water-vegetation-atmosphere model was explored.

Bref résumé du projet

In the northern hemisphere, three major black soil zones located along the mid-latitude across Northeast China, North America and southern Russia-Ukraine, contribute greatly to the world agriculture. However, after several hundred years’ cultivation, they are facing many problems such as erosion, contamination and salinization, which threaten their sustainability. There is urgent need to measure the state and to understand the evolution and the future of the black soil associated ecosystems to support sustainable land use plans. “Earth critical zone” initiative develops an integrated structure to research the near-surface environment of the planet, and provides a good solution to comprehensively study the black soils.

This project will investigate "how the black soil forms and evolves", "what it looks like now" and "where we should go for its sustainable use", involving "multi-spheres", based on "multi-disciplinarily", and using "multi-techniques". An observation system using remote sensing, geochemistry and critical zone observatories will be established for a comprehensive understanding of the black soil critical zone and its mutual impacts with global change. The research might extend to other black soils, e.g., Pampas Prairie in South America if possible. The outcomes including data and observatories will be open to the public for education and research purposes.

The co-leaders are internationally recognized researchers in these topic areas from leading academic institutions in Australia, Canada, Czech Republic, Greece, Russia, United Kingdom, Ukraine, and the United States.
