- The planning regions are classified into micro, meso and macro planning regions.
- These planning regions are classified on the basis of physical, economic and ecological factors.
A. Micro Regions:
- Micro regions are ‘smallest’ and ‘lowest’ level of hierarchy of planning region.
- Micro regions are different from adjacent areas in term of certain characteristic and potentialities.
- Any small region has potential for the development and promotion to any single specialization such as agriculture (Punjab plain), Hydro power (HP), Tourism (J&K) etc.
B. Meso Regions:
- Meso regions lie at the middle of the hierarchy of planning region combine in themselves a few micro region.
- At least two micro region combined to form one meso region.
- Meso region are multipurpose region. (ex. Damodar valley basin)
- Meso region posses at least one specialization of production cycle of national importance as well as a number of nodal center of both national and regional significance.
- The main objective of delimiting meso region is to curve out the viable unit for the effective exploitation, conjection and utilizing of resource.
C. Macro Regions:
- Macro region are the largest of all planning regions in the three tier system of planning region.
- It is a large areal unit with greatly diversified natural resources capable of being a self contained region with a self generating economy to support a high quality of life.
- They are formed by combined two or more meso regions.
- The size of macro region for planning purpose also can not be standardized.
