Water management problems related major reservoirs and irrigation systems in Polonnaruwa District, Sri lanka

In Polonnaruwa District, Sri Lanka's dry zone, water scarcity poses significant challenges for agriculture, particularly rice cultivation. A study reveals that current irrigation systems fail to meet farmers' demands in terms of adequacy, reliability, and timeliness, despite the region's potential for increased paddy fields through improved water management. The research analyzes monthly reservoir conditions, including rainfall, irrigated area, water yield, and storage levels, focusing on major reservoirs like ParakramaSamudraya, Giritale, Minneriya, and Kaudulla. It highlights the critical need to address water distribution inefficiencies to sustain food production amid growing competition from domestic and industrial sectors. The findings underscore the urgency of optimizing irrigation scheduling to mitigate water scarcity in this vital agricultural region.
