Climate change is affecting agricultural production and is expected to continue reducing water availability, potentially necessitating adaptation of related sectors to maintain sustainability of saline land use system highly vulnerable to water shortages.Practically, droughts have posed impacts on salt-affected land use of coastal region in Jiangsu Province.The main purpose of this paper is to determine who is least adaptive and what factors limit its/their adaptive capacity to drought in saline land use system of Jinhai farm located on the coastal reclamation region of north Jiangsu Province, china.We defined vulnerability and adaptive capacity of saline land use system to climate change and variability, evaluated the effects of drought on the coupled natural-human system of Jinhai farm, results indicate that drought has produced sharp reduction in rice yield and farmers income.In order to better understand the adaptive capacity of farmers, we conducted semi-structured interviews with representatives of households and farmer in Jinhai farm and related sectors about the main limit determinants in adaptive capacity.It showes that physical factors restriction (including soil type, surface water, groundwater, and salinization of soil) and social elements involved imperfect irrigation and drainage management, crop selection and arrangement, institution deficits, and governance commonly lowered these farm households adaptive capacity.Though they have taken some adaptation measures such as turning rice field into fish pond, and building channels drawing fresh water, it still seemed lack of long-run and regionally integrative considerations.Our results highlight the importance of a comprehensive and integrative management in beach development and planning with multi-sectors and representative entities participation.
