Effective crop structure adjustment under climate change

Choosing effective responses to the adverse impacts of climate change is a challenging issue worldwide. Crop structure adjustment is a primary strategy to effectively respond to climate change and maximize climatic resources. However, quantitative analysis of crop structure adjustment is a difficult process. This study proposes an effective evaluation method for crop structure adjustment that combines vulnerability and contribution rate assessment. Selection of prior crop with lower vulnerability, higher climate change contribution rate, and lower agricultural technology contribution rate can effectively address the adverse impacts of climate change and maximize climatic resources at a lower cost. A case study comparing spring wheat, potato and naked oat in Wuchuan County of Inner Mongolia, China determined the feasibility and practicality of this method.
