Sustainable Livelihoods and Biodiversity inRiparian Areas in Developing Countries
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!
