Analysis On Multi-stakeholders’ Flood Adaptative Capacities In The Daying River Basin

Climate change-induced floods are increasing around the world.Formulating climate change adaptation policies and improving the resilience of floods and droughts are strategic measures for countries,governments at all levels,and even individual societies to cope with the impacts of climate change.At present,kinds of research on flood adaptation mostly put forward the necessity and urgency of adaptation policy formulation,but lack relevant analysis and research from policy formulation to grassroots implementation and its effectiveness.Taking the Dayingjiang River Basin,a highincidence area of flood disasters,this paper uses key person interviews and household survey methods to conduct a detailed survey of 3 counties/cities and relevant government departments,and 205 rural households affected by floods in the basin and based on revealing the construction and characteristics of the flood adaptation path of the three types of flood adaptation subjects in the basin,and the disaster reduction results from the formulation of flood prevention measures to the implementation,the flood adaptability of the three types of subjects are assessed to provide Chinese confirmation cases for the study of the effectiveness of climate change adaptation strategies.The main conclusions are as follows:1.The concept of flood control in the river basin has expanded from flood control and flood management to flood adaptation.Flood control countermeasures in river basins have expanded from engineering measures as the mainstay and engineering and non-engineering measures to multi-level and multi-subject consultation and participation in flood control.2.The construction of two sets of top-down flood prevention and disaster reduction systems(relevant government departments – villages/village groups-group survey group-families)with counties as the unit,with flash floods and mudslide geological disasters as the goal and river floods as the goal has been completed,and the timeliness of flood monitoring and early warning and emergency response has been significantly improved3.The monitoring and early warning capabilities of the government-collective-family,the emergency response capability,and the recovery and adjustment capabilities are coordinated with each other,such as the government’s flood control project construction and organization of relocation;the village organizes villagers to carry out berm construction,protect the cultivated land to resume production;and the construction of water barrier facilities for each household,various types of agricultural insurance and other disaster reduction measures,so as to realize the complementarity of governmentvillage-family flood prevention measures,improve flood prevention effectiveness,production,and life recovery capabilities4.Compared with the losses caused by the same magnitude of floods(once in 50years)that occurred in the basin before,the current flood control system has reduced the number of victims,the number of fixed assets such as houses damaged,the area of agricultural disasters and direct economic losses by 67.95%,47.67%,49.28%,and48.46% respectively,indicating that the impact of floods has been greatly reduced and the resilience to floods has been significantly improved.
