Unique Flood Hazard Atlas: Odisha

Odisha has come out with a unique flood hazard atlas aided by satellite imagery, which is expected to help the coastal state manage floods more efficiently. The atlas was released by Odisha Chief Minister Naveen Patnaik at the State-level Natural Calamity Meeting.

About Flood Hazard Atlas

Need: Atlas would serve as a useful resource of information for policy makers, planners and civil society groups.

Base Period: Atlas is compiled on basis of historic flood inundation captured via satellite imagery over 18 years period from year 2001 to 2018.

Methodology:

Firstly, all satellite data sets were analysed and flood layers were extracted from it, then all flood layers corresponding to a particular year were combined into one inundation layer, so that this layer represents maximum flooded area in 1 year period.

Then all such combined flood layers for a period of 18 years were integrated into flood hazard layer representing observed flood-inundated areas with different frequencies. This layer was integrated with digital database layers of Odisha.

Key Findings of Study

The National Remote Sensing Centre (NRSC) of Indian Space Research Organisation (ISRO), Hyderabad had undertaken a study on Odisha’s flood hazard zonation.

Floods in Odisha: Every year vast areas of Odisha are inundated when there is flooding in major rivers of state, viz. Mahanadi, Subarnarekha, Brahmani, Rushikulya and Baitarani. Also, as per Odisha State Disaster Management Authority (OSDMA), damages due to floods are mainly caused by Mahanadi, Brahmani and Baitarani, which have a common delta where floodwaters intermingle and when in series simultaneously cause havoc.

Flash Floods: Few districts in western and southern part of Odisha are prone to flash floods which are caused due to instant run-off from hilly catchments areas of rivers like, Vamsadhara and Budhabalanga.

Hazard Prone: The entire coastal belt is prone to storm surges, which is commonly accompanied by heavy rainfall which then makes estuary region vulnerable to both storm surges and river flooding. Few districts in Odisha’s western and southern part of are prone to flash floods.

Hazard Categories: As per NRSC analysis during 2001-2018, about 8.96% (13.96 lakh hectares) of land in Odisha was affected by floods. Out of this 13.96 lakh hectare flood-affected area nearly 2.81 lakh hectares of land falls under high inundated flood hazard categories (7-9 times) to very high inundated flood hazard categories (10-14 times).

Odisha Government launches Saura Jalnidhi scheme

Odisha Government has launched Saura Jalnidhi scheme to encourage use of solar energy in irrigation by farmers. Under this scheme, farmers will be given 90% subsidy and 5,000 solar pumps. This will provide irrigation benefits in 2,500 acres of the state. The beneficiary of this scheme will be farmers who have valid farmer identity cards and have minimum 0.5 acres of agricultural land.

Saura Jalnidhi scheme

The scheme was launched as part of state government’s endeavor to increase the use of solar photovoltaic pump sets in those areas so that irrigation facilities can be provided where power system is bad. For this scheme, state government has made a provision of Rs 27.18 crore in the financial year 2017-18.

In the first phase, this scheme will be available in those areas where electricity is not available for running the pump set. This scheme will generate 1.52 lakh human day employments annually and provided livelihood to around 5,000 families and also reduce carbon footprints.

Under this scheme, farmers will be provided with a well-equipped solar pump irrigation system in convergence mode. It will help to reduce burden of input cost on farmers and also increase agricultural income. It will promote the use of green energy and reduce pollution.
