| Abstract: |
Utilization of land reclamation area offers the potentiality of increasing greenery as
well as providing forest products. This study refers to the identification of the land
reclamation areas and potential plantation areas on the Bagmati river-basin in the
Terai region of Nepal, and recommends appropriate species for plantation in order
to rehabilitate such areas. Multi-temporal Landsat Satellite Images (Landsat 7 and
Landsat 8) were acquired for 2002 and 2014. Object-based Image Classification
method was used to classify the land cover classes into four broad categories: i) Water,
ii) Sand and gravel, iii) Plantation potential (open areas suitable for plantation) and
iii) Others (forest, agriculture, built-up areas etc.). The Mean Normalized Difference
Water Index (NDWI) values and Mean Brightness values were found to be helpful in
identifying the water and sand & gravel areas from the other land cover classes. The
overall classification accuracy was 0.97 with a kappa coefficient of 0.89 in the case of
the 2014 Image classification. In this study, the land reclamation area referred to the
areas occupied by water, sand & gravel on the river-beds that were converted into
plantation potential and other classes between 2002 and 2014. Similarly, the potential
plantation area referred to the summation of the area of reclaimed land, the area of
‘Others’ class converted into ‘Plantation potential’ class and the area that remained
to be plantation potential on the bed of the Bagmati River and its tributaries between
2002 and 2014. Altogether, 4,819.10 ha land was reclaimed in the study area, and a
total of 5,395.10 ha land was found to be potential for plantation within the study area.
