NEESPI current status and its objectives within northwestern Eurasia

http://neespi.org

Recognition

Pavel Groisman, NEESPI Project Scientist

UCAR at the NOAA National Climatic Data Center,

Asheville, North Carolina, USA

Rationale for NEESPI

1. Strong interactions in the system terrestrial ecosystem - atmosphere hydrosphere -cryosphere - human society and feedbacks to global energy, water, and carbon cycles in the region

2. Strong climatic and environmental changes….

The

NEESPI

Study

Area

NEESPI Study Area includes: Former Soviet

Union, Northern China, Mongolia,

Fennoscandia, & Eastern Europe

NEESPI is an interdisciplinary

program of internationally-

supported Earth systems and

science research that addresses

large-scale and long-term

manifestations of climate and

environmental change.

NEESPI duration ~ 10 years (started in 2004)

The NEESPI Science Plan (available on

http://neespi.org) has elements that address

concerns of WCRP, IGBP, IHDP, and

DIVERSITAS Programs

NEESPI and the actions to develop

its Science Plan were initially

promoted by NASA and Russian

Academy of Sciences (2003-2004).

RAS

Since early 2005, the NEESPI community

has worked to make NEESPI inter-agency

(in the U.S.) and international.

NEESPI AND ITS PAST

• How do Northern Eurasia’s terrestrial ecosystems dynamics interact with and alter the biosphere, atmosphere, cryosphere, and hydrosphere of the Earth?

This question can be reformulated in a pragmatic way as:

• How do we develop our predictive capability of terrestrial ecosystems dynamics over Northern Eurasia for the 21st century to support global projections as well as informed decision making and numerous practical applications in the region?

Our concern is that the changes in this region have the potential to affect the entire Earth System and may already be doing so.

The overarching NEESPI science question:

NEESPI Science plan major focuses• Focus on transient zones that are most vulnerable in

the future changes– Coastal zone– Tundra-forest– Forest-steppe– Steppe-desert– Mountains

• and on “Boundaries”• Focus on feedbacks that make the projection of the

future changes uncertain– Biogeochemical feedbacks– Biogeophysical feedbacks– Human activity

Major concern:

Ecosystems and climate interactions

in the region are very strong.

But, various biogeochemical and

biogeophysical feedbacks are poorly

understood and are difficult to

project.

• In a warmer climate, there will be an intensification of bioproductivity, B+B, and thus a sequestration of some fraction of the anthropogenic CO2 will occur.

• For example, boreal forest located in the regions of greatest warming and a general surface heat deficit is a primary candidate for this negative feedback. But, what if ...

Example: Classical biogeochemical

feedback

… the area of the boreal forests changes?

... the rate of release of methane and CO2

from soil increase?

The above may generate a potential

runaway scenario of a strong

positive biogeochemical feedback.

• Plus, there are several other “if”…

But, what if…

“Uncertainty” is the answer…

Example of hydrology-vegetation feedback.

Net Ecosystem Exchange [positive CO2 flux stands for

source to the atmosphere]. The sign of annual NEE

to have in ~10 years• A suite of process –oriented models for each major

terrestrial process in all its interactions • A suite of global and regional models that

seamlessly incorporate all regionally specific feedbacks associated with terrestrial processes

• An integrated observational knowledge data base for environmental studies

• To bring the Earth System research in the region to the level it deserves

NEESPI Deliverables:

Current NEESPI Statistics (April 2010):

More than 560 scientists from more than

200 institutions of 30 countries are working

on more than 130 individual funded

projects under the Initiative umbrella (with

annual budget ~$15M), several more

projects are in the process of joining

NEESPI. Four major sponsors of NEESPI

remain: the United States, Russia,

European Union, and Japan.

Additionally, NEESPI receives in kind assistance from EU,

US, Russian, Chinese, Japanese, Ukrainian and

International Agencies and Institutions.

Example of in-kind assistance

To support a Summer Workshop-School in Fedorovskoe (Russia, July 2007) on Boreal Forest Environmental Studies, sponsors from– Japan (National Institute of Environmental Sciences),– China (Beijing Normal University), – Russia (Severtsov Institute for Ecology, Russian Foundation for

Basic Research), – Germany (Friedrich-Schiller-University),– USA (NASA, Maryland University), – The International Arctic Research Center, Fairbanks, Alaska,

and – private US and Russian companies

swiftly came together with a 6-digit sum of money.

Two modes of NEESPI expansion• Dedicated Calls (recent NASA and RAS and perspective in

the NIS, EU, and China)

• Freely joined projects

• Benefits of the NEESPI membership

– Improved links to collaborators in Northern Eurasia and to US and EU scientists working on similar problems

– Exchange of ideas, datasets, and knowledge with other team members working on similar problems

– Synergistic approach in working on complex problems

– Priority access to remote sensing and in situ data collected over Northern Eurasia

– Education: student exchange, doctoral and post-doc positions sharing among the Team Institutions

Why we have to be expedient in our research in Northern Eurasia?

The changes are already here and they have been large!

Changes of the northern boundaries of forest and steppe zones along the 39E (past 13x103 years) (Kozharinov

and Puzachenko 2005)

…and large changes are projected…

... were large in the past...

Water (0),Tundra (1), forest-tundra (2), darkleaf taiga (3) and lightleaf taiga

(4), forest-steppe (5), steppe (6), semidesert (7), and polar desert (8).

Biome distribution over n. Eurasia east of 60°E

in current (a) and 2090 (b) climates (Vygodskaya et al. 2007)

In addition to large climatic and environmental changes,

we are facing a non-linearity in environmental and climatic

changes in Northern Eurasia right now due to

– Dramatic retreat of the Arctic sea Ice that is causing

• rampaged coastal erosion (up to 10 m yr-1)

• release of carbon (both, methane and CO2) stored in the frozen shelf and coast (Shakhova et al. 2009), and

• additional source of heat and moisture in early winter

– Impact on the World Ocean thermohaline circulation due to changes in the fresh water inflow into the Arctic Ocean

– Feedbacks to the global carbon budget & climate due to• Permafrost thaw

• Wetlands transformation

• Land cover changes and

• Ecosystems shift

Example 2:

Land use dynamics in the

past 60 years in the Volga

River Basin show that 13

Mln Ha of agricultural land

(or ~20%) have been

replaced by forest (10 Mln)

and reservoirs (3 Mln)

[Golubev, Speranskaya &

Tsitsenko 2003]

… as well as by the changes

caused by human activity:

Example 1:

More than 90% of steppe

and forest-steppe zones in

Northern Eurasia is

currently cropland (orange

areas in the map)

Thus, it looks like within Northern

Eurasia we have to study:

Human activity changes

Climate system changes

Greenhouse gases changes

Ecosystems’ changes

and

their interactions

Problem was not the large changes

themselves but understanding of their

causes and timely projections

• Hydrological cycle

• Human impact on the Baltic Sea Environment

• Changes in extremes (see next slide)
