Abstract
The study was conducted to map and monitor the agroforestry areas in Yamunanagar, Ambala and Panchkula districts of Haryana state from the year 2000 to 2019 through geospatial techniques using LISS-III (2000, 2005 and 2010) and LISS-IV (2015 and 2019) satellite data. Apart from mapping and monitoring, an attempt has been made to identify potential agroforestry sites like scrubs, fallows and piedmont areas on LISS-IV dataset of 2019 by on screen digitization technique for future cultivation of agroforestry species by farmers in the study area. Supervised method of classification technique was adopted to classify LU/LC classes like agroforestry, agriculture, forest, built-up, waterbodies, plantations and riverbed areas. The results of the study revealed that, agroforestry area delineated in Yamunanagar for the year 2000 (3,898.62 ha), 2005 (5,403.17 ha), 2010 (7,134.90 ha), 2015 (14,650.51 ha) and 2019 (17,022.76 ha). In Ambala 2000 (2,696.48 ha), 2005 (3,745.33 ha), 2010 (7,400.92 ha), 2015 (12,350.91 ha) and 2019 (15,552.53 ha). In Panchkula 2000 (1,098.15 ha), 2005 (1,212.8 ha), 2010 (1,784.03 ha), 2015 (2,034.87 ha) and 2019 (2,367.12 ha). The accuracy of the image classification was delineated based on the ground truth data and accuracy found in agroforestry was 90% for Yamunanagar, 95% for Ambala and 93% for Panchkula districts By the extraction of vector layers from the classified raster image, blockwise monitoring of agroforestry areas was delineated and change in various categories of LU/LC by performing overlay analysis in ArcGIS platform was detected and results revealed were (5,678.5 ha) in Yamunanagar, (6,783.6 ha) in Ambala and (1,202.6 ha) in Panchkula, the agriculture areas were converted to agroforestry areas from the year 2000 to 2010 and (14,486.6 ha) in Yamunanagar, (13,534.8 ha) in Ambala and (1,866.2 ha) in Panchkula, the agriculture areas were converted to agroforestry areas from the year 2010 to 2019. Based on the groundwater quality, soil condition and rainfall factor in the study area, potential sites were digitized, the results revealed that, about 10,525.76 ha of the potential sites were identified and mapped in Yamunanagar, around 12,179. 85 ha in Ambala and 4,023 ha in Panchkula districts. Based on the study, it is concluded that with the use of LISS-III and LISS-IV satellite data accurate mapping of agroforestry areas can be delineated which would help the planners in monitoring and identification of hotspots for suitable interventions in the districts.
