Land - Atmosphere Project
• off-spring of BAHC, IGAC, GCTE, GAIM• full and pro-active partnership with WCRP, story of a truly
complementary approach• learning from the past, capitalizing on successes of this
collaboration (GEWEX-BAHC, LBA, ...)• stepping stone for future joint programmes (mainly with WCRP
GEWEX)

Biota, Aerosols, Clouds, and Climate
• Biosphere/climate feedback proposed in 1987, in which marine phytoplankton emits a volatile sulfur-containing substance (DMS)
• DMS oxidized to sulfate aerosol particles that serve as cloud condensation nuclei (CCN)
• Increased CCN ->more cloud droplets -> clouds brighter ->reduced amount of sunlight absorbed by the Earth
• Earth cooling -> changing the living conditions for plankton, and thus their rate of DMS emissions
![Page 9: WAGENINGEN UR - CCB CLIMATE CHANGE AND BIOSPHERE RESEARCH CEntre from a misconception to a key thematic focus from the past](https://reader036.vdocuments.us/reader036/viewer/2022070306/5517b84855034645368b61ad/html5/thumbnails/9.jpg)
Biota, Aerosols, Clouds, and Climate
• feedback thought to be relevant mostly to the oceans, continental regions considered always to have high levels of CCN, so that clouds would never be “CCN-starved” and any additional CCN would have little effect
• recent work in the Amazon shows this assumption to be wrong: in the wet season with no detectable anthropogenic input, the balance of natural sources and sinks produces a CCN number concentration almost identical to marine values.

Biota, Aerosols, Clouds, and Climate
• By providing most of the CCN to the natural atmosphere, the biosphere has a strong influence on cloud radiative and microphysical properties, and thereby on both climate and the hydrological cycle.
• This natural regulation mechanism is now in the process of being overwhelmed by anthropogenic emissions

Scenario Projection: 2000-2100
• When climate change is neglected (blue line) the coupled model produces a CO2 trajectory similar to the standard IS92a scenario as used in GCMs (black line).
• When climate-carbon cycle feedbacks are included (red line) we see much higher rates of CO2 increase and climate change.
• By 2100 the fully coupled model produces 970 ppmv and a global warming of 5.5K (c.f. 700 ppmv and 4K without climate-carbon cycle feedbacks).

Climate, Water Quality & Ecosystems
Turbid water A stability landscape of ecosystems (source Scheffer, 2001)
• Aquatic Ecosystems , sometimes are in a seemingly steady state despite human pressures (lack of early warning signals)
• Gradual decline in ecosystem resilience can result in a sudden shift caused by an (climatic) event like a flood or a drought
• Also climate change (T) reduces ecosystem resilience
Clear water

Current political barriers global change & climate issues:
• Spatial & Regional (sectoral) political power structures
• National power structures
• Barriers to sustainability ofcurrent practices in IRWM
How?
• International policy in relation to driversglobal change (emissions, land use, pop. Growth, etc), conventions,like CBD, UNFCCC, CCD, RAMSAR
•Actual measures at local level
