Description
Summary:A study area covers Ninh Binh Province as a whole that has 67.125 hectares of agricultural land, including 55.125 hectares of arable land. Ninh Binh has 13 major drainage basins. Water resources are unevenly distributed across the catchment areas. Due to a dense drainage system, every year Ninh Binh is hit by heavy flooding during the wet season. With a total length of all channels and a lock-weir network, just 22.4 % of channels are concrete lined, i.e. only every fourth kilometer of channels is concreted, thus leading to high irrigation losses. To tackle current challenges related to the effective use of irrigation systems in Ninh Binh, it is necessary to organize annual inspections and assessments of the current state of water supply networks, irrigation systems, etc.
