Delineation of agro-climatic zones
Agro-climatic zones are of paramount importance for defining or
delineation of agro-ecological zoning for sustainable use of land resources. The
essential elements in demarcating or defining of an agro-climatic zone are
bioclimates based on thermal regimes, moisture regime and biomass variability (Fig. 5). Thermal regimes indicate to the amount of heat available for plant
growth and development during the growing period. Moisture regimes
represent water availability for crop production and hence they are the vital
to classify the agro-climatic zones. Nine different agro-climatic zones were
delineated by GIS aided integration of thermal regimes, moisture regimes and
biomass map layers (Fig. 5).
