   • In many areas, the quality of water may not be appropriate for irrigation, resulting in clogging of sprinkler nozzles and other complications.
   • Access to clean water sources is essential for effective sprinkler irrigation.

4. Infrastructure Development:

   • Insufficient infrastructure for water delivery can restrict the reach of sprinkler systems, especially in isolated regions.
   • Investments in rural infrastructure must be prioritized to ensure better accessibility.

5. Agricultural Policies:

   • Inconsistent agricultural policies and a deficiency of long-term strategies can generate uncertainty, deterring farmers from investing in sprinkler irrigation.
   • Well-structured and supportive policies are essential for encouraging sustainable practices.

6. Climate Variability:

   • Shifts in climate patterns may result in unforeseen droughts or excessive rainfall, impacting the operational efficacy of sprinkler systems.
   • Adaptive strategies and resilience planning should be integrated.

Way Forward: Detailed Solutions
