Steep slope cultivation agricultural landscapes are widely distributed in the world and significant to crop production. Terrace agricultural systems is one of the common cultivations in steep slope cultivation agricultural landscapes, which is significant in producing vines, orchards, rice, maize, etc. However, these precious landscapes are under the threat because of climate change such as more frequently intensive rainfall events and long period of drought. Improved information on runoff analysis in the terrace systems is significant to the sustainable agronomic practices and reasonable water resource management. The aim of our work is to analyse the threats and challenges of steep-slope agriculture due to climate change and provide examples of resilient water management, to mitigating the agricultural lost due to extreme rainfall and water scarcity. In detail, our work focusses on: (1) To find more practical and effective water management measure in terms of water conservation and environment protection. (2) To designed different kinds of water reservoir for terrace agriculture and simulate the efficiency of water storage on runoff trapping under different climate scenario. (3) To better analyse, through appropriated high-resolution topography-based models, surface hydrology in terrace landscapes. (4) To quantify the flow reduction and water storage amount by applicating of designed water storages facilities. Our study provides the guideline for both farmers and government in constructing reasonable and effective water resource management, which is meaningful for developing sustainable steep slope agricultural landscapes and improving the resilience of terrace cultivation systems in future climatic conditions.
