The ratio of gross cropped area to the net sown area is called cropping intensity.Gross Cropped Area (GCA) is the sum of areas under all crops sown during the year, counting area sown more than once in the same year as many times as it is sown. Net Sown Area (NSA) is the total area sown with crops only once during an agricultural year. Cropping intensity is calculated as (Gross Cropped Area / Net Sown Area) * 100. It indicates the degree of multiple cropping practiced on the same land during a year.
