Water management units (WMUs) in polders need to be created and managed based on the hydrology of the landscape and the shared interests of those farming within the units. In addition to reducing water management conflict, the creation of small WMUs would allow farmers to take advantage of more productive cropping system options. Such units might be 50 to 100 hectares in size.
