Odisha is one of the most natural calamity-prone states in India. Its unique geographical
position with six big and innumerable small rivers, 480 km long coastal belt along the
Bay of Bengal, and the irregular and unpredictable behavior of monsoons make it highly
susceptible to natural calamities, causing colossal damage to life, property and livelihood
systems. Among the natural calamities frequenting the state, the more common are drought,
flood and cyclone. Over the years, both the frequency and severity of these calamities have
increased considerably and they are striking new areas every year. Droughts and floods have
become an annual affair and cyclones a more or less regular occurrence in the state. These
three calamities affect the state economy, and more particularly its agriculture, extensively.
There is no gainsaying that agriculture is the backbone of the Odisha economy in terms
of its share in Gross State Domestic Product (GSDP) (25.2%) and total employment (57.7%),
and rice is the staple food of the people of Odisha. On account of the subsistence nature of
the crop and the typical agro-climatic conditions in the state, almost all farmers in the state grow rice. On the average, it is grown on an area of 44.5 lakh ha in the state, though there
are fluctuations in area from year to year due to natural calamities. The rice area, on the
average, accounts for 91% of the total area under cereals and 49% of the gross cropped area
in the state. Kharif rice covers 93% of the total area under rice and contributes 89% to total
rice production. Two-thirds of kharif rice is grown under rainfed conditions. During kharif
season, the crop is grown under a variety of unfavorable situations resulting in low yield
(Venkateswarlu et al., 1994). Studies have recorded that droughts and floods occur almost
every alternate year in Odisha (Reserve Bank of India, 1984; and Samal, 2004). Needless to
say rice production is the greatest casualty of the natural calamities in the state. They not only
impose direct loss by destroying the standing crops, but also entail loss of production in many
other indirect ways. From the analysis of 123 years of rainfall data, Sivasamy (2000)
concluded that the present knowledge of the causes of drought does not permit extrapolation
of these events into the future. As the rainfall distribution is highly uncertain, the present
knowledge and existing methodology have limited applicability to predict the exact
distribution of rainfall. Hence, the predictability of rainfall in a particular year and occurrence
of natural calamities like drought, flood and cyclone is very poor. The effects of climate
change in recent years have further exacerbated the occurrence of natural calamities (Johl,
2006; and Bouman et al., 2007). |
