Environmental assessment for small- and medium-scale road projects implemented in local authority areas: A case study from Thailand

Trethanya, S and Perera, R (2009) Environmental assessment for small- and medium-scale road projects implemented in local authority areas: A case study from Thailand. Journal of Construction in Developing Countries, 14(2), pp. 55-76. ISSN 1823-6499

Abstract

In developing countries like Thailand, an Environmental Assessment (EA) is conducted only for projects prescribed by environmental legislation. Numerous projects, especially those that are small- and medium-scale in size and scope, are implemented in areas by a local authority without any type of EA. Based on a comparative analysis of the environmental status of large-, medium- and small-scale road development projects implemented by a local authority in Thailand, this paper attempts to justify the enforcement of EAs for medium- and small-scale projects. The justification is mainly based on the perceptions of people affected by these projects. Environmental impact scores, computed on the basis of people's perceptions, reveal that, irrespective of the size of a project, the impacts caused by different sized projects are perceived as similar. Since every development project is implemented for the purpose of human development, this paper proposes to integrate environmental screening and initial EAs into the existing development control measures enforced by urban planning regulations and laws.

Descriptive scope: 5 PCTEA

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
