Researching impact of drought on agricultural production and proposing adaptation measures in Quang Nam province

This paper used record of observed rainfall data and rainfall data measured by applying the Tropical Rainfall Measuring Mission (TRMM) to assess the situation of drought and proposes drought adaptation measures under the climate change condition in Quang Nam province. We found that: (i) During 1980-2017, drought in Quang Nam province was quite serious and there was a difference between mountains, midlands and plains; (ii) Droughts in Winter-Spring crop often occurred in Eastern, Southern and Southeast regions of the province. In Summer-Autumn crop, drought appearred very erratic throughout province and there was no specific spatial trend; (iii) According to climate change scenario of the Ministry of Natural Resources and Environment, it is forecasted that by 2035, drought in Winter-Spring crop will be serious in Southern region. In Summer-Autumn crop of 2035, drought will expand throughout midland and delta areas of Quang Nam province; (iv) In order to adapt to drought in the use of agricultural land in Quang Nam province, it is necessary to synchronize construction and non-construction method.
