ment of rivers in the risk zone should be repaired to avoid breaching. Beyond this, as the storm approaches the area, nothing can be done.

Protection ofcrops against wind

Crop damage by winds can be minimised or prevented by the use of windbreaks (shelterbelts). ttese are natural (e.g. trees, shrubs, or hedges) or artificial (e.g. walls, fences) barriers to wind flow to shelter animals or crops. Properly oriented

and designed shelterbelts are very effective in stabilizing agriculture in the regions where strong wind causes mechanical damage and imposes severe moisture stress on growing crops. Windbreaks prevent the loose soil being lifted by erosion and increase the supply of moisture to the soil in spring.

Tropical cyclones andstorm surge

Coffee and bananas suffer the direct loss of fruits and mechanical damage due to tropical cyclones. Nonetheless, food crop losses were estimated to be higher (35%), while the livestock sector was less affected (8%, of which one fifth was poultry), tte effects of strong winds in coastal areas are seen in stunted and often very sculpted trees providing the evidence of the direction of the strong winds. Fields inundated by the storm surge suffer a loss of fertility due to salt deposition, even after the sea water has receded, tte affected land takes a few years to regain its original fertility.
