Questions

These are example answers to some of the key questions at the end of each chapter.

Chapter 1

Q2. Some steps in the EIA process have proved to be more difficult to implement than others. From your initial reading, identify which these might be and consider why they might have proved to be problematic.

  • Answers to this question can vary from country to country, as you will see especially in the examples of international practice in Chapter 10. However there are some common, longstanding and difficult steps.
  • For example , although in the EU there are also considerable variations, reviews over time have highlighted some continuing problems which are common to many of the Member States, including :
    • the limited practice of mandatory monitoring, and associated auditing;
    • variable and partial approaches to participation in the EIA process;
    • very limited consideration of alternatives;
    • over-comprehensive approaches to scoping EIA content (and resulting over-voluminous EISs);
    • failure to include some key elements, such as climate change issues;
    • weak (tiering) linkages between EIA and SEA studies.


Q8. What do you understand by a multi-dimensional approach to the environment, in EIA?

  • Pioneering, and much of contemporary, EIA practice, has focused on the impacts of development actions on the bio-physical environment. This was a deliberate response to a concern about the lack of consideration of such impacts of development.
  • Yet, decision makers are often faced with the dilemma of assessing the wide mix of impacts on both the bio-physical and socio-economic environment and the interactions between the two. Impacts on air and water quality can, for example, have major impacts on human health.
  • Socio-economic impacts have been the 'poor relation' in EIA, but this is slowly changing with more recent practice giving much more attention to 'people impacts'. There are considerable merits in adopting an integrated approach to EIA – one which includes both the bio-physical and socio-economic.
  • However, partly reflecting the growing significance of socio-economic considerations, there has also been an increasing practice of a more semi-detached Socio-Economic Impact Assessment (SIA) activity. A further proliferation has included the major growth area of Health Impact Assessment (HIA), and Equalities Impact Assessment (EqIA).
  • Finally, it should also be noted that the consideration of the environmental dimensions does vary between countries, with relatively more focus on the socio-economic dimensions in developing countries.


Q13. What are the main differences between EIA and SEA?

Table 11.1 (Chapter 11) provides a succinct summary of the main differences ---
