Like Environmental Impact Assessment, HIA can be made by the following
methodologies:
(i) Ad hoc method
(ii) Checklist
(iii) Matrix
(iv) Network
(v) Overlays
The list of these methods is neither complete nor final. Different methods used in
risk analysis, vulnerability mapping, environmental impact assessment, social
impact assessment, etc., can be used or modified for predicting.
The quality of impact prediction depends on the ethics, value and knowledge of
analysis team and reviewing team. The public participation of the risk exposed area/
community is essential to come out with good management plan. Public participation also depends on knowledge, economic status, social status of the participating
group as different people will have differing status and all are provided with equal
opportunity to express their opinion.
2.4 Ad Hoc Method
In this method, broad areas of health impacts are identified; besides, the nature of
the impacts is qualitatively grouped and explained. Even though this method can be
easily applied, the consultant or the report-preparing personnel can intentionally
hide facts. If the report preparer is not knowledgeable, he/she would usually refer
and reproduce the same facts which he/she is refereeing to.
2.5 Checklist
Checklists identify heath impacts of development activities on selected parameters.
Check lists can be broadly classified into four types:
A. The simple checklist (Table 2.3): This type of checklist is merely a list of parameters and nature of impacts.
B. The descriptive checklist (Table 2.4): This type of checklist contains guidance on
evaluation of the parameters.
C. The scaling checklist (Table 2.5): This checklist is similar to the descriptive but
with supplementary information on the scaling of the parameters.
D. Scaling-weighting (Table 2.6): This type of checklist is similar to scaling checklist but with supplementary information on the subjective evaluation of
parameter.
