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 Paharare becoming totally dry.

5. Objectives of the Study • To study the current status of water bodies in comparison to last one decade (2000-2010) • 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.

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
