Scope and Approach
- Figure 1 provides an illustration of the framework for hydrology in REWARD. Annex-1 gives the details.
- REWARDS, being a P for R (Program for Results) project, payments are to be made by the World Bank to borrowers only on achieving agreed results.
- A total of 705 MWS (micro-watershed) covering an area of 5,26,695 ha is to be covered under REWARD in Odisha over a period of 5 years starting from May, 2021-22. Out of this, 152 MWS (Set 1) covering 1, 08,498 ha would receive investments for watershed treatment that is based on science (LRI, Hydrology, etc.). In the remaining 4, 18,196 ha. (Set 2), all scientific investigations needed for watershed treatment and management would be collected, ported to the digital library such that draft DPRs (Detailed Project Reports) could be generated from the digital portal using relevant DSSs. The table below shows the timing of inputs needed for the two sets of MWS:
|State||Set 1: Saturation Watersheds – DPRs ready by end of 2 years||Set 2: LRI Assessment Area – Completed by end of 4 years||Total area to be covered under REWARD|
|Odisha||1,08,498 ha||4,18,196 ha||5,26,695 ha|
|LRI & PILOT CLUSTER FOR REWARD|
|SL.NO.||DISTRICT||BLOCK||NO. OF MWS||GEO.AREA IN ha||SL.NO||BLOCK||NO. OF MWS||GEO.AREA IN ha|
- For each set of MWS (Set 1 and 2), a few model MWS sites would be selected for hydrological investigation (including setting up instruments, collecting data, validating models, etc.) such that they represent the whole set. The criteria, inter alia, could be based on geographic formations, dominant soil types, major crops and agro-climate of the area.
- In Set 1 area, once the watershed treatment has been carried out, benchmark sites would be selected (mainly based on LMU) where hydrological monitoring would continue till end of project.
- Comprehensive set of data at the cadastral level (1:8000) on land, its use, shape, soil type, crops grown, etc., classified and grouped into Land Management Units will be available from LRI survey that will be carried out in Set 1 & 2 area under REWARD.
- A consortium of technical partners comprising Agricultural Universities would work together under the leadership of a national institute to carry out the assignment in the entire area. Each partner, including the lead partner would be allotted a defined set of MWS to work in the field. The lead partner, in addition, to carrying out the work in their allotted MWS is expected to provide, guidance, handholding support, training and supervision to other partners.
- For interfacing with the community, especially for demand side management pilots (ground water management and water advisories), REWARD will partner with the Groundwater department and/or hire capable NGOs. Technical partners for hydrology are expected to provide technical backstopping in the form of providing data, advisories, training, technical training materials, etc.
- The IIT Bhubaneswar/OUAT/ IIWM/ IISWC Sunabeda have been identified as technical partner for hydrology in REWARD for Odisha.
- 1) About 25% of the MWS in Set 1 are expected to be selected for post-treatment monitoring and in each a maximum of 3 sites are expected to be selected as benchmarked sites.
2) This should cover the technical approach for Set 1 and Set 2 MWS. It should provide details of methods/models are proposed for use in each component of water balance.
