Regarding methods for impact assessment, although RIA Handbook suggests
to state agencies to assess impacts by a quantitative approach, there is no detail

on how this type of assessment can be made. Hence, several RIA reports fail to
quantify the impacts and merely present them in a prescriptive manner.

In addition, RIA Guidelines and RIA Handbook do not separate an assessment
approach for social impact but rather provide general rules applied for all types of
the assessment. This begs the question of whether the study of the experience of

other jurisdictions can help fulfil this absence or not.

The existence of a social dimension of impact assessment
regime in an international level (Chapter 3)

Chapter 3 presents knowledge bodies of impact assessment approaches
from an international level perspective. It focuses on the knowledge bodies found

at international instruments, guidelines and suggestions of institutions widely
adopted internationally. The guidelines published by OECD and EU are examined
by focusing on a social dimension. The objective is to examine the extent to

which OECD and EU instruments provide guidance of impact analysis approaches
and methods.

Key findings from Chapter 3 include the conclusion that after 2010, there is
no guiding document of OECD and EU separating assessment of social impacts.

The impact assessment approaches for all types of impacts are the same. The
knowledge bodies extracted from this study can be applied to the Thai context.
However, RIA in the EU provides specific assessment types, regarded as sub-type

of social impact. Examples are gender impact assessment, environmental
assessment, and health assessment. Another observation is that the structures and

approaches for assessing the impacts under OECD and EU regimes are similar, but
those published by the EU are more comprehensive than those of the OECD.
