1 Mono-decade Change Detection of Water-resources in a Cluster of Villages in the Kala Pahar with specific reference to Taoru-Nuh Aravali Range using High Resolution Satellite Images Dr. Subhan Khan (Chief Scientist, NISTADS, New Delhi) & Mr. Khushpal Dahiya (President, SGSD, V.P.O-Rohat, Distt. – Sonipat)

2 Presentation Structure  Introduction  Vision of the Study  Proposed Approach and Methodology  Implementation Strategy  Data Analysis  Issues Finding

3 Introduction  A jointly implemented project by National Institute of Science Technology and Development Studies (NISTADS) and Society for Geo-informatics & Sustainable Development (SGSD)  Sponsored by NRDMS Division, Department of Science and Technology (DST), Government of India

4 Conceptualization  Most of the settlements in Aravali hills are located in periphery of hills where they found a natural resource of water like pond or stream. Which is the main resource of livelihood for village people and their animals.  In past few decades, a drastic change has been observed in existence of active water bodies in the periphery of Aravali hills which were mainly sourced from Kala Pahar are becoming totally dry.

5 Objectives of the Study  To study the current status of water bodies in comparison to last one decade ( )  To identify the major reasons behind the change. If any?

6 Study Area  The study is restricted to cluster of villages in Taoru Block of Mewat District, Haryana.  It is located between 28 10’ to 28 12’ 15” North and 76 57’ 15” to 77 East covering half dozens of villages in Taoru-Nuh Aravali range fringes including villages namely Chilla, Pachgaon, Buraka, Chharora, Bhajlaka, Salaka, Malaka & Shikarpur.

9 Data Analysis Active Pond in Year 2000 (LISS & PAN Merged Data) Dry Pond in Year 2010 (Q.B. Data)

10 Data Analysis Active Stream in Year 2000 Encroached Stream in 2010

11 SOI Totographic Map & Satellite Image-Change Detection

12 Results  The major reasons attributed to the waterlessness of these water bodies include  deforestation- cutting of trees for meeting the fuel and fodder requirements  Grazing- loss of natural root stock of vegetation due to excessive grazing  These above two factors led to loss of water from Aravalis  uncontrolled & unregulated and illegal mining in the Kala Pahar that poses a grave danger to Aravali region in Mewat; led to diversion of natural flow  considerable encroachments on water flow routes & water outlet from hills to drains leading to water bodies by village people.

13 Recommendations  Creation of check dams and water harvesting structures on watershed basis  Removal of illegal encroachments from the natural streams  Natural Resource Management with people’s active participation and promotion of alternate income generation activities to check illegal cutting of trees/mining/grazing /encroachments, etc.  Plantation and conservation of local tree species of Aravalis
