| Abstract: | Land suitability analysis is prerequisite for sustainable agriculture and it plays a pivotal role in the niche based agricultural
planning in mountain regions. In this paper different parameters viz. climatic (precipitation and temperature), topographic
(elevation), soil type and land cover/land use have been used in order to perform land suitability evaluation for cereals
food-grain crops in Himachal Pradesh using Geographic Information System (GIS). The suitability analysis was performed by
digital processing of geo-referenced data (elevation, climate, soil and landcover) and calculating potential production areas
by combining different types of geographical data through decision rules framed for each crop in ArcView spatial analyst.
Suitable areas have been delineated for cereal crops in the form of land suitability maps. In comparison to the actual area
under cereal crops, the possibility of further expansion under each cereal crop was determined. These discriminated areas
appear suitable for growing these crops and can be harnessed efficiently for achieving long term sustainability and food security. |
