The present article relates to water governance, and within that a specific Hungarian problem, namely, the cumulative water-related damage occurring in the Great Plain (floods, droughts and inland water) and the ambiguous situation of environmental services. Due to the complexity of the problem, the solution itself can only be systematic and can therefore only be solved in the context of integrated and adaptive water management. In Hungarian, this water management is defined as landscape-oriented water management by a research group connected to the Hungarian Academy of Sciences. The possible implementation of landscape-oriented water management has recently emerged in connection with the development of agricultural irrigation. The novelty of this study is the assessment of the new Hungarian Act concerning the irrigation taking into account the different aspects of hydrology, pedology and jurisprudence.
