6.51 (assuming land acquisition cost of Rs. 20,000 per acre). The likely income that can be realized from the fish tank can be in the range of Rs. 0.3-0.5 million, after deducting the cost of investment. This income stream will help meet the annual maintenance cost of shelters as well as other community facilities. Vulnerability of the live stock population as well as the cycle/flood hazard incidence indicate that construction of community cattle shelter should be given top most priority for 3 CD blocks in South 24 Parganas district – namely Basanti, Gosaba and Patharpratima as reflected in Table 6-2.

Mobility Improvement Mobility improvement can significantly alter the magnitude of loss. Firstly during the emergency phase, i.e. during the period for evacuation, rescue, humanitarian assistance – where steps are taken to save lives and provide essential supplies to those most affected. Secondly, during the recovery phase for restoration of normalcy – mostly to allocation of manpower and resources to undertake repair and retrofitting activities. Therefore, it is of enormous importance to upgrade mobility (intraregional as well as intra regional) of these two coastal districts to increase the coping capacity from cyclone and flood hazards. Existing mobility pattern for goods and people indicate predominance of road based modes. However, in some parts of the South 24 Parganas district waterway navigation is extensively used. Identification of the CD blocks has been done based on the level of road connectivity along with degree of hazard proneness, as indicated in the Table 6-3. Table 6 -3. Existing Transportation infrastructure in CD blocks identified for mobility improvement C.D Block Road Connectivity Index Cyclone Hazard Level Unsurfaced Road (km) 0 - 5 Km.

Capacity augmentation and surface quality improvement of existing road links This is done by upgrading the existing unsurfaced roads to Single lane WBM (Water Bound Macadam) roads. Total Expenditure: Rs. 167.3 Crores approximately [Conversion of 4227 kms Unsurfaced road to WBM roads @ Rs. 0.8 million/km] 2. Identification of missing links A detailed look into the village level connectivity indicates that some of the villages are yet to have direct access through surfaced roads. Apart from these, culverts, bridges at key
