  1. New Challenges in the European Area: Young Scientist’s 1st International Baku Forum BAKU CITY, AZERBAIJAN REPUBLIC,  MAY 20 – 25, 2013 NEW APPROACH TO THE MEASUREMENT OF ENVIRONMENTAL IMPACTS: OBJECTIVITY AND REPLICABILITY Sofia Viegas, Portugal

  2. Environmental Impact Assessment(EIA) • crucial preventive tool in environment policy and spatial planning • best way to promote sustainable growth • important to develop efficient tools In particularyto quantifying environmental impacts on Biodiversity

  3. Quantifyingan impact • enables assessing its importance • allows the establishment of effective measures to avoid, minimize and/or compensate for its effects • it is globally accepted that the necessary tools must be objective, accurate and producing scientifically verifiable results

  4. Framework • While accepting the need for expeditious and objective methodologies for EIA, information on how to implement these methodologies is clearly limited • Although there are guidelines to quantify impacts, typically this is not done • At present there is no uniformity of methodologies to assess the impacts, preventing the rigorous and objective comparison between different projects • There is great difficulty in defining such methodologies for biological descriptors (flora and fauna) – given its dynamic nature and the difficulty in parameterizing

  5. Main Goal • create a methodology to quantify environmental impacts on biodiversity • to meet the demands of Portuguese legislation (stemming from European law) • completed with information from several national and international sources that are involved in EIA Extended research was undertaken in order to improve currently used methods

  6. Results • The proposed methodology consists of an algorithm that combines two components: • magnitude(quantity and quality of environmental modified receptor) calculated through indicators that were specifically developed to achieve this goal • incidence(severity of impact) calculated through combining attributes that further describe the impact

  7. Results Impact Value (Vi) = Magnitude × Incidence Sum of the values ​​of the partial impact total impacts numberofimpacts Scale of significance negligible impact verysignificantimpact

  8. Results • An objective, scientifically verifiable and replicablemethod to quantifyimpacts • The end result of this algorithm is a better evaluation of impact • grading it through a scale that characterizes impact in order of significance • allowing the comparison between projects

  9. Discussion • Work done focuses on one important issue in Environmental Impact Assessment: Manage constraints of: • Time • Resources • Costs • Quality • Accuracy • Feasibility Ensure the best quality / price / brevity
