Integrated Land Ecosystem
Atmosphere Process Study
Outgoing Co-Chair: Alex Guenther, UC Irvine
Co-Chair: Hans C Hansson, Stockholm Univ.
Incoming co-chair: Eleanor Blyth, CEH
iLEAPS
Focus on core science of land ecosystem – atmosphere
interactions
Atmosphere
Ensure the social
science aspects in
initiatives and projects
Biosphere
Anthroposphere
iLEAPS Science
H2O, CO2, CH4
N2O, VOCs, pollen,
NOx
O3, N2,
Aerosols
Undisturbed forest
Managed forest
Tropical, Boreal
Temperate
Husbandry
Tree species
Interaction
Crops
Farming practice
Crop type
Vulnerable, marginal or
extreme environments
Cold, dry
wetlands, mountains
Issues: Human Health, Biodiversity, Climate mitigation, Food and fuel security
1. How changing land-use and farming and forestry practice (irrigation, tillage,
fire, draining, fertilisers, grazing, forest husbandry, pest and weed control,
choice of crops or trees) affects the atmospheric chemistry, air quality and
climate (N2O, CO2, H2O, CH4, VOCs, pollen etc)
2. How anthropogenic changes in atmospheric chemistry (CO2, O3) affects plant
productivity (ozone damage, CO2 fertilisation)
3. How vulnerable and marginal ecosystems (very cold, very dry) will be
affected by changes in climate (T, H2O, CO2)
4. How ecosystems (including fire, wetlands and vegetation) emit short lived
carbon: e.g. isoprenes and methane as well as carbon dioxide and its impact
on the atmospheric chemistry
iLEAPS organization
• IPO at Nanjing University, China
– since March 2015
– Nurmira Zhamangulova (Exec. Officer), Aijun Ding (PI)
• Regional offices/nodes
– Regional Future Earth offices
– Node for the MENA countries at the Cyprus Institute
– Institute of Meteorology and Climate Research (IMKIFU), Garmisch-Partenkirchen?
– Other possibilities?
• National offices: Japan, Korea, China
Regional responses to human
intervention
Regions where emissions of reactive compounds, fire, irrigation, or land-cover
change distort the predictions of global models. Adapted from Pitman et al. 2011b.

Project example: Interactions among Managed
Ecosystems, Climate, and Societies (IMECS)
iLEAPS-ESA project: Multivariate analysis of Earth
Observations to produce a Biosphere-Atmosphere Index
including Fire, Soil water stress, Evapotranspiration,
Photosynthesis, Crop productivity, Land use change
Earth Observation Product
Multi-variate Analysis
Product Example:
LULC /Air quality interaction research
Lead: HC Hansson
Air Quality
Climate
Natural ecosystems
Food / Forestry productivity
Land use / change
Products:
Land use/change index (in effect on CO2, O3, BVOC)
Air Quality effect on Ecosystem index ( in effect on productivity CO2, H2O flux)
That is iLEAPS!
