Selection of Study Sites for the Warna Basin Case Study

YASHADA, Pune 16 October 2009

Issues in selection

Different levels at which different phenomena work

Different scales Need to be representative as well as to

capture specifities Need to capture different aspects Feasibility within given resources,

contacts etc.

Two kinds of selection

Representative sample of villages, based on broad zonation

Different communities of special interest (here the study will not necessarily be village based)

Different special interest sites, locations (here too the study will not necessarily be village based)

Some degree of chicken and egg problem for selection

Village selection

First, a review of what information we have at hand for zonation

Information from toposheets, isohyets, soil map and census data

We have to base our zonation on the info from these sources

Streams

Spot heights

Contours

DEM

Slope classes

Isohyets

Geology

Soil fertility index `N’

Soil fertility index `P’

Village layer with census information

Suggested zones

According to isohyets:– 2000 mm and above– 800 mm to 2000 mm– Up to 800 mm

According to slope class – Plains (up to 3%)– Others (undulating

Distance to river (Warana main + 2 main tributaries)– On river banks– Away from river bank

Suggested village selection - 1

Three isohyet zones – main reference point Above 2000 mm

– One village from river bank– One village away from river banks

800 to 2000 mm– One village from river bank, plains– One village away from river banks with >3% slope

class

Suggested village selection - 2

Up to 800 mm– One village from river bank, plains– One village away from river banks with >3% slope

class

Plus– One village on National Park fringe upland– Two villages within National park (Satara and

Ratnagiri)

Suggested village selection - 3

Not fully random: need for contacts and co-operation

In at least half of these full scale PBR (with some adaptation) will be attempted (hopefully in all); in the rest, with somewhat reduced scope.

Suggested selection of communities

Dhangars (separate for large and small animal rearing? For buffalo and cows rearing?)

Shifting cultivation Bhois Bagadis Buruds Resettled dam displaced Resettled sanctuary displaced Single women? Religious minorities (Muslims, Lingayats, Jains,

Christians?)

Suggested selection of specific sites

One mining affected site One pollution affected site Special features on the river

– Meander (Kokrud?)– Oxbow lake– A case where malis (river bank forest/gallery forest?) exist and

one where they have disappeared– Two doha

Sacred groves KT weirs (include in vilage selection?)

Thank you for your patience!
