Abstract: Climate change is affecting agricultural production and is expected to continue reducing water availability, potentially necessitating adaptation adjustment by related sectors to maintain sustainability of saline land use system highly vulnerable to water shortages. The drought in 2010 impacted the salt-affected land use system of the coastal region in Jiangsu Province, China. The main purpose of this paper is to determine which systems are least adaptive, and what factors limit their adaptive capacity to drought, among three typical saline land use systems of Jinhai farm located in the coastal reclamation region of north Jiangsu Province. An analytical framework for analyzing climate impacts and adaptation for saline agriculture is presented. To better understand climate change impacts and the adaptive capacity of saline land use systems, we conducted semi-structured interviews and group discussions with representatives of surrounding households and the farmer on Jinhai farm, experts and officials from government sectors and institutes. From these conversations two impact indicators were picked up and a set of determinants for adaptability and their rankings were derived. There is considerable variability in climate change impacts among different saline land use systems and a concentration of impacts on paddy systems.  Adaptability in addition to climate change is cumulative to the impacts, particularly unsafe water resource planning, irrational land use mode and crop arrangement, and defective institutions and policies. Our results highlight the importance of a comprehensive and integrative land development planning involving water resource and land use arrangements participated in by representatives of stakeholders. Although there has been  much  progress in streamlining  climate  change assessments into sector planning in Dafeng–such as water resources,  agriculture, beach and so on – it is clear that  there is a need to improve institution, policy, market guidelines and technique R&D to ensure more consistent adaptation, especially  considering the rapid evolution of the climate science behind the assessments. Achieving sustainable saline agriculture might require transformative changes in markets, policies, and science.
