e.g. man-made and climate induced changes in Europe
Water – 20% of all surface water
sources seriously threatened by pollution
Soil Erosion – 17% of total European land area affected,
economic loss around 85 € per ha
Biodiversity – 335 species highly
endangered in Europe
Agriculture – intensification leads to water stress,
soil erosion and biodiversity decline
Urban Settlements and transport networks growing - leads
to soil sealing and fragmentation of landscape
Man-made impact & climate variability – require adaptation
Directives & Regulations – requesting geo-spatial monitoring

Context
 Global Monitoring for Environment and Security
(GMES) aims to provide, on a sustained basis, reliable
and timely geo-information services related to
environmental and security issues in support of public
policy makers’ needs
 GMES is an EU-led initiative, in which ESA implements
the space component and the European Commission
manages actions for developing services, relying on
both in-situ and space-borne remote sensing data.
 GMES basic architecture
 Infrastructures: In-situ and Space data
 Core Mapping Services : Generic products
 Down-stream services: End-users applications
 “Fast Track” Services
 Marine Monitoring
 Emergencies Response

Needs for a Global Land Monitoring Core Service

2
geoland
Why?
 Because environmental protection and civil security are global issues
that require global monitoring to provide an informed basis for action.
 EU 'development' policies




European Consensus on Development (Enviroment, Water, Agriculture, Rural Devl)
European Consensus on Humanitarian Aid
Joint Africa-EU Strategy (AMESD, GMES & AFRICA)
Other relevant policies (Thematic Strategy for Food Security, Environment and
Natural Resources Thematic Program (ENRTP), EU Water Initiative (EUWI))
 International environmental treaties




UN Framework Convention on Climate Change (UNFCCC) (eg. Kioto Protocol).
UN Convention to Combat Desertification (UNCCD)
UN Convention on Biological Diversity (UNCBD)
UN Forum on Forest (UNFF) + UN Millennium Development Goals
 Link with other international initiatives


Global LMCS will be part of GEOSS
Linked to GCOS, GTOS, IGOS, CEOS…

 Definition of product ‘status’:
 Development: Products under development
 Pre-operational: Products generated routinely and available to beta-users
for evaluation. Further improvements are expected after validation.
 Operational: Products generated routinely and validated.
 Accuracy level:
 Threshold accuracy: Minimum acceptable quality.
 Target accuracy: Commitment from the producer.
 Optimal accuracy: Maximum expected accuracy.

Conclusions: Stresa Workshop on Global LMCS

Identification of key products/issues, user requirements

Global Monitoring: Land Cover & LCC, Vegetation & Fires, Water & Soils, Snow &
Ice

Hot-spot Mapping and Thematic Services

Integration of complementary info (EO, in-situ, models)

Architecture: Atmosphere/Marine services could be used as a model

Research/expertise support to operations: quality, validation, improvements, new
products

Need of continuity of products in time, reprocessing

End-to-end information chain: need of integration (EO, in situ data, land surface
models, land cover change, carbon & water cycles, crop monitoring) through land
data assimilation systems and human expertise
