The probable impacts of climate change on poverty - UNDP

estimated that 1.39, 1.26 and 14.48 lakhs hectares <strong>of</strong> crop land was affected by flood in 2005, 2006 and 2007,
respectively. Cyclone Sidr has fully destroyed 300,940 ha <strong>of</strong> Transplanted Aman and partially damaged 700,533 ha
(Draft report on cyclone Sidr, CDMP). <strong>The</strong> following table shows yearly damage <strong>of</strong> rice variety by flood and
cyclone.

Usually adverse <strong>impacts</strong> <strong>of</strong> <strong>climate</strong> <strong>change</strong> on soil quality and its subsequent effects on crop are not recognized.
Experts interviewed informed that temperature variation could increase biotic activity <strong>of</strong> the soil and increase
deficiency <strong>of</strong> soil nutrient and likely to reduce crop production. It has also revealed that flood has both positive
and negative impact on soil. In the case <strong>of</strong> land covered by sand which degrades the quality <strong>of</strong> soil while silt
deposition improves soil quality which has positive impact on crop production.
It is evident that the higher the magnitude <strong>of</strong> flood, the higher the damages <strong>of</strong> crop agriculture. It is found that
flood <strong>of</strong> 1998 and 2004 cause significant damage to crops. <strong>The</strong> following figure shows relationship between area
inundated and damage to crop.
