Rationale for water management under RRA
• Current water crisis is mired in the race to the pumphouse – for irrigated crops.
• The importance of water in RFA is not even recognised as a challenge.
• Moisture management and critical ‘protective’ irrigation are important to improving RFA. These two aspects emerge as priorities in the use of water as a common pool resource –THE BASIS FOR WATER MANAGEMENT PILOTS IN RRA EFFORTS…

Progress – activities (year 1)
• Design of work and integrating RRA work with ACWADAM’s core work on hydrogeology and groundwater management
• Understanding the macro-picture through a situation analysis in a few locations• Instrumentation and data• Kharif planning – in at least three locations
![Page 10: Water Node: RRA](https://reader036.fdocuments.net/reader036/viewer/2022062310/56816698550346895dda83db/html5/thumbnails/10.jpg)
Progress - results• Water: controls –
establishing arguments regarding soils, aquifers and water sources
• Data collection, including data on weather parameters
• Synthesis of data into a GIS frame
• Diversity in controls – geology, soil, water inputs, degree of water use
• Inequitous water access even on local scales
• Scales – watersheds, aquifers, land-parcels

Improving soil moisture and prioritizing areas for protective irrigation
![Page 13: Water Node: RRA](https://reader036.fdocuments.net/reader036/viewer/2022062310/56816698550346895dda83db/html5/thumbnails/13.jpg)
Risks & assumptions• Data collection
• Interface with CPs and other nodes
• Sufficiency and capacities of available Human Resources
• Steady but clearly evolving
• Good progress in about 4 CPs, need to pick up in the others
• Some limitation due to stretched HR but filling gaps with available resources possible
![Page 14: Water Node: RRA](https://reader036.fdocuments.net/reader036/viewer/2022062310/56816698550346895dda83db/html5/thumbnails/14.jpg)
Shorter term…first year+
Basic parameters Completed/ongoing activities• Reconnaissance visits to all the CP sites
completed, with emphasis on understanding argo-hydro-geological setting
• Hydrogeological understanding in terms of the access to irrigation and soil-moisture status plus some understanding between soil –cropping pattern –water utilization understood in case of 3-4 sites
• Developing protocols for polling of water resources/grouping water –users to facilitate protective irrigation in upcoming kharif – under process
• Materials and models being compiled to conduct training and capacity building sessions specifically on water in RFA
• Characterising agro-eco-hydro elements of core CP area
• Situation analysis wrt to some CPs where implementing the interventions regarding protective irrigation are possible
• Developing action plan to facilitate protective irrigation for the maximum coverage of area which area more prone to droughts

Institutional arrangement and support systems
InputsKey results (achieved/expected)• Integration of inputs by water
node and kharif planning – 2-3 locations
• Key inputs to analysis of groundwater and weather-related data, including installation of weather stations in 4 CP locations
• Support in co-ordination of meetings, skypes and in interface with other nodes
• Strong interface in data collections, field support and in development of the framework for baselines, including interface with ResRA
• Project
• Organisation
• Network (Secretariat)
• Other nodes/CPs

Analysis and reflections - 1• Strengthening the
argument of water as protection in RFA
• Layering at a certain scale achieved; convergence easier on some counts

Is groundwater only about
mainstream irrigation??

Analysis and reflections - 2• Given the complex, but
compelling nature of the collaborative framework of RRA, things are moving, albeit slower than expected.
• Key takeaway: development of a specialised pool of HR must be taken up for RRA on a priority basis.
![Page 22: Water Node: RRA](https://reader036.fdocuments.net/reader036/viewer/2022062310/56816698550346895dda83db/html5/thumbnails/22.jpg)
Way forwardWater node• Proposed activities to continue,
into 2nd year with strong interface of research and application component (including data synthesis)
• Rebudgeting for second year, using balance of budget from 1st year
• HR, including interns, will be mobilised to cover more locations – possibly all the 9-10 locations by the end of year 2
Network• Need a plan for conducting
comprehensive capacity building – cutting across thematic nodes and CPs and including a research component
