373 The Development, Application and Validation of Agri-Environmental Indicators

Oral Session
S06 Soil & Water Management & Conservation Agri-environmental indicators are derived from mathematical models that integrate soil, air, climate, landscape and management (crops, livestock, fertilizers, manure, etc.) information to evaluate the impact of agricultural practices over time at both regional and national levels. These indicators (eg. water contamination by N & P, soil erosion, GHG emissions, biodiversity, etc.) determine whether soil, crop and water management practices are environmentally sustainable and thereby identify soils and climatic regions which may be at risk.  Using this information, researchers and policy makers can target environmentally sensitive areas as well as develop agricultural production systems which are truly sustainable from both and economic and environmental perspective.
