Integrated water resources management (IWRM) has been defined by the Global Water Partnership (GWP) as "a process which promotes the coordinated development and management of water, land and related resources, in order to maximize the resultant economic and social welfare in an equitable manner without compromising the sustainability of vital ecosystems". == Development== The development of IWRM was particularly recommended in the final statement of the ministers at the International Conference on Water and the Environment in 1992 (so called the Dublin principles). This concept aims to promote changes in practices which are considered fundamental to improved water resource management. In the current definition, IWRM rests upon three principles that together act as the overall framework: # Social equity: ensuring equal access for all users (particularly marginalised and poorer user groups) to an adequate quantity and quality of water necessary to sustain human well-being. # Economic efficiency: bringing the greatest benefit to the greatest number of users possible with the available financial and water resources. # Ecological sustainability: requiring that aquatic ecosystems are acknowledged as users and that adequate allocation is made to sustain their natural functioning. IWRM practices depend on context; at the operational level, the challenge is to translate the agreed principles into concrete action. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Integrated water resources management」の詳細全文を読む スポンサード リンク
