What is it? Why do it? When to do it? How to do it? How to use it? Conditions calling for CEIA Good practice EIA and beyond Large vs. Small projects 2 “ Cooking up ” Cumulative Impact Assessment 3 Key Terms Valued ponent (VEC): “… elements of the natural and human world that are considered valuable by participants in a public review process. ”? Can be valued for economic, social, environmental, aesthetic or ethical reasons ? Important in themselves and/or serve as indicators ? Represent the focus of any EIA or CEIA ? Can be large scale or small scale/specific (lake basin > lake > spawning area) ? Identified and prioritized by stakeholders, experts, weighting schemes 4 Environmental system Valued Ecosystem Component Potential impacts on VECs Issues/ Indicators Air Ambient air quality Pollution, concentration of particulates Respiratory impacts, acid rain Surface water Local river Reduced volume/ changed flow regime, contamination, changes in course, Seasonal drying, low water quality, flooding Groundwater Local aquifers Depletion, contamination Dry or contaminated wells Aquatic resources Populations of fish species in local river/lake Reduced water habitat, pollution, temperature changes Reduced catches, reductions in dependent species Vegetation Local native forest Clearing, logging, increased fires, invasive species, effects of air or water pollution Loss of aesthetic/ cultural/ consumption/ tourism value, disruption of hydrological cycles, erosion Terrestrial fauna Endemics, Red List spp , culturally or economically valued spp , munities and processes Loss of habitat/food sources, hunting, invasive species, effects of air or water pollution Loss of aesthetic/ cultural/ consumption/ tourism value, disruption of ecological processes Zone of Impact: Area passing all VECS which could be impacted by the project … Based on ecology, topography, etc. – not just a s
