iLEAPS Science Undisturbed forest Vulnerable, marginal or extreme environments CropsManaged forest H2O, CO2, CH4 N2O, VOCs, pollen, NOx O3, N2, Aerosols Interaction Husbandry Tree species Farming practice Crop type Cold, dry wetlands, mountains Tropical, Boreal Temperate 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 (N 2 O, CO 2, H 2 O, CH 4, VOCs, pollen etc) 2.How anthropogenic changes in atmospheric chemistry (CO 2, O 3 ) affects plant productivity (ozone damage, CO 2 fertilisation) 3.How vulnerable and marginal ecosystems (very cold, very dry) will be affected by changes in climate (T, H 2 O, CO 2 ) 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

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.
