Activities of ICP M&M2004 - 2006andResults of the 21st TF meeting Till Spranger
The 2005 Task Force meeting... • back-to-back with CCE WS: 25 - 29 April 2005, Berlin • 45 participants from 24 NFCs + (Secretariat), WGE, EMEP Centres and ICPs. • ... had the following main subjects: • cooperation with EMEP (land cover, base cation deposition, HM deposition) • call for data results (HM) • Call for data results (N&S: critical loads and dynamic modelling results) • Nitrogen
Cooperation with EMEP • Much higher CL(N, S) exceedances than 1998 dataset • mostly due to land cover specific MSC-West Unified Model • Harmonized Land Cover • Will (hopefully) be available late summer 2005: • CORINE LC where available; SEI elsewhere; hierarchical links to national LC databases by NFCs • Ecosystem classification: EUNIS • Base cation deposition • Important for CL(acid); backup for NFC data • New data available (MSC-West UM) • To be further tested and amended • Historical S, N (and not BC) deposition • Important for dynamic modelling • Heavy metal deposition • Critical load exceedance report with EMEP MSC-East
Heavy Metals: Call for data results See WGE document /10 Add.1; CCE / MSC-East Report • CLs for various effects on ecosystems and on human health • 17 NFCs submitted CL data (16 for Cd, Pb; 9 for Hg), mostly for effects in or via terrestrial ecosystems • Further work on timescales of recovery / damage
Sulfur and Nitrogen: Call for data results See WGE document 2005/10 and CCE Status Report • 14 NFCs submitted revised CL data (overall data from 25 NFCs) • 14 (13) NFCs submitted additional input data for dynamic modelling and target loads • Rest of Europe filled in by background database • ensures that information on sensitive ecosystems is representative on a European scale • „CL and TL data robust for policy application“ (i.e. IAM) • -> can / should be used as basis for Gothenburg Protocol revision and CAFE
Sulfur and Nitrogen: CL exceedances See CCE Status Report • Exceedances have been reduced, but remain widespread especially for eutrophication: • Area exceeded for acidification in 1980 / 2010 • in total Europe: 49% / 7% • in EU25: 49% / 13% • Area exceeded for eutrophication in 1980 / 2010 • in total Europe: 38% / 29% • In EU25: 81% / 66% • Maxima mostly in areas dominated by NH3 emissions
Nitrogen • CLs of nutrient nitrogen remain strongly exceeded even after GP implementation • Strong links to biological processes, climate change • Aim: (dynamic) modelling of biodiversity and other N deposition related effects on a European scale in an IAM framework • Further work necessary on, a.o.: • Choice of effects indicators (e.g. C/N,... ), dose/effect relations, and critical limits • Assessment of interactions between air pollution and climate change (e.g. long-term C and N sequestration, long-term N2O, CH4 etc. emissions) • National approaches (NL, D, SE, DK, ...) • Cooperation with other ICPs, JEG and external networks

Nitrogen and M&M:Links to external developments • NitroEurope etc. (primary research) • COST Action 729 (research synthesis, source-receptor links) • ESF Project (multiple N forms& impacts; management) • International Nitrogen Initiative • CBD Indicators (SEBI 2010):N Deposition
CBD EEA/ECNC SEBI 2010 European Transboundary Nitrogen Activity
COST 729 Challenges • Much knowledge on causal chain and interaction with other cycles • Development and extension of IAM necessary • Source - receptor modelling, including atmosphere biosphere interactions and climatic influences • Non-linearities and coupling with other cycles • Nr affects climate (N2O, aerosols) • Climate change affects SRM through meteo and chemistry • Feedback mechanisms
Conclusions on Nitrogen • CLRTAP effects-based emission abatement policy has been successful for S but not as much for N; it needs to be extended / linked to biodiversity and climate change policies and targets • Multi-media and multi-effect research and policy development needed to • reduce uncertainties • link and optimize management and abatement strategies
Summary: M&M Future • Classic tasks: • Input to Multipollutant and HM Protocol review / possible revision • Input to EU CAFE process • New focus: • Nitrogen deposition – biodiversity – climate change • Aim: Modelling of biodiversity and other effects of nitrogen in an IAM framework • Instruments: • dynamic modelling with feedbacks, using effects indicators such as C/N, BS; • help with extension of IAMs? • Cooperation with CLRTAP internal and external organisations
NitroEurope Challenges • What are the quantitative components of nitrogen budgets for European ecosystems and how do these respond to the drivers of global change? • How much does nitrogen control carbon exchange and net greenhouse gas budgets for European terrestrial ecosystems? • How could a European N emissions strategy contribute to EU objectives in reducing greenhouse gas emissions?
ESF Proposal:Nitrogen in Europe: Assessment of current problems and future solutions • Assessment of alteration of (European) N cycle • Scientific Network Programme (5 years): • Provide overviews of literature, current studies, databases and models relevant for the N cascade • Grants for exchange visits • Workshops • Summer schools • Conferences • Databases, models • Webpage, dissemination
(Other) uses of critical loads data • Review of the EU NEC Directive • CAFÉ / Thematic Strategy • CBA & LCA • Don´t use CLs in full CBA • Use in MCA is OK • Impact factors for LCA • Data rules
