ANNEXES

Annex I

Screening of Thana level schemes from environmental considerations

Environmental impacts of small schemes

Name of schemes:

The objective of assessment of environmental impact is either to accept or discard a scheme.

The score will not be counted in the decision matrix.

The various adverse impacts of scheme in environment will be assessed and the degree of impact will be recorded as nil, very low, low, medium, high and very high. The score will be 10 for nil, 8 for very low, 6 for low, 4 for medium, 2 for high and 0 for very high. The following table is to be filled up to get the average score.

Total score =

Average score = Total score/6 =

Any scheme with an average score of less than 5 should be discarded from further analysis.

Amex II

Ranking of Thana level schemes after environmental screening

Ranking of small schemes

There are four variables that would be used while ranking the schemes. These variables are listed in Table 1. Table 1 is to be filled up based on information gathered for every scheme from steps I and ii of the methodology for small schemes.

No.	Variables	Schemes
		1	2	3	4	5
1	B/C ratio	........
2	Number of man-days required during construction (in thousand)	........
3	Net benefited people	........
4	Number of land holdings with area less than or equal to 5 acres	.......

Then a decision matrix as shown in Table s will be prepared as follows.

Each scheme will be given a score between 1 to 10 for every variable in Table 1. Higher score will be given for higher value and will be proportional to the values among the schemes. The scores will be added to get total score at the bottom of the Table 2 for every scheme. The scheme with the highest total score will be given the rank 1, the second highest score will be given rank 2, and so on. If the total score for more than one scheme become equal, then preference will be given to scores obtained for variable no. 1. If that does not solve the problem of ranking, then preference will be given to variable no. 2 and so on.
