HTML Document OO. 5.4 Identify in strategic planning the negative and positive effects of the different sectoral policies (land-use planning, transport, energy) on priority elements of biodiversity, and take measures to correct or strengthen these effects

Release date 16/06/2009

Activities with potential negative impacts must be identified and investigated in order to determine the exact causes and effects of those activities on biodiversity. These analyses will allow solutions (including better alternatives) to be identified that avoid or minimise the impacts of sectoral policies on biodiversity.

Activities must be boosted that have a potentially positive effect on the conservation and sustainable use of biodiversity. Early discussions between the sectors and biodiversity experts could help identify such ‘win-win' situations and improve the positive interactions.

Through clear and legally binding rules, competent authorities should not approve projects and plans that would lead to irreversible damage for the priority elements of biodiversity, unless justified by imperative reasons of major public interest.

Therefore environmental impact assessment (EIA) and strategic environmental assessment (SEA) procedures must include biodiversity criteria and should refer to relevant national policy documents such as the Belgian Biodiversity Strategy, the CBD and biodiversity-related conventions and agreements.

In order to promote a participative environmental policy, it is important to link the strategic planification (evaluation of impacts of plans and programs related to environment) with public participation, as required by the European Directives.

The Convention on Environmental Impact Assessment in a Transboundary Context (Espoo, 1991) and its protocol and amendments set out the obligations of Parties to assess the environmental impact of certain activities at an early stage of the planning process. It also lays down the general obligation of individual states to notify and consult each other on all major projects under consideration that are likely to have a significant adverse environmental impact across national boundaries.
The assessment of impacts caused on biodiversity by projects and plans is already provided for by the European legislative framework:

  • Directive 85/337/EEC requires an environmental assessment of series of projects that may have an impact on biodiversity
  • Article 6 of the Habitats Directive requires that an appropriate assessment be undertaken for any plan or project which, either alone or in combination with other plans or projects, would be likely to have a significant effect on a Natura 2000 site.
  • The Strategic Environmental Assessment Directive (2001/42/EC) requires that certain plans and programmes from the public sector be made subject to systematic environment assessment. The SEA directive specifically mentions biodiversity as one issue that has to be reported on in the environmental report.

These dispositions have been transposed into the Belgian Federal and Regional legal framework. However, there is a need to provide guidance to the initiators of relevant projects, plans and programmes to assess whether their projects, plans and programmes would be likely to cause any significant effects on biodiversity and if so, whether they should be subject to an SEA (for example, development of guidelines or establishment of an advisory committee including biodiversity experts). Furthermore, a set of criteria on biodiversity aspects to be taken into consideration during the environmental assessment, i.e. in the evaluation report, could also be useful in this regard.
