5.6 (2004 prices) prevalent in district mandis. Intrusion of salinity in soil reduces the productivity of the land, inflicting significant opportunity costs as well as restoration costs on the cultivator. Given its role in income and employment in the study area, the Vulnerability Index of Pisciculture (B) has also been estimated from the total fish production and prevailing local market prices. It should be noted that intrusion of salinity from storm surge related inundation diminishes the yield of the fish production, both for sweet and brackish water pisciculture. Similarly, the Vulnerability Index of the Livestock and Animal Husbandry (C) has been estimated by their market value prevalent in the local markets. A = Total value of annual agricultural output ( INR) in ith CD block i B = Total value of fish output ( INR) in ith CD block i C = Total value of livestock ( INR) in ith CD block i All the three indexes have been normalized in the following way, for better inter CD block wise comparison of vulnerability, in parts and also in entirety. Aˆ = i Ai − A A − A max min min Bˆ i = Bi B max − B − B min min Cˆ i Ci = C max − C − C min min Figure 5-2: Vulnerability mapping of the local economy in the coastal districts of West Bengal
5.7 The Composite Vulnerability Index for the Local Economy (E) has been assessed by considering the vulnerability indexes of agriculture, pisciculture and livestock [Refer Table 5-2 and Figure 5-2].
