| Abstract | Over three decades, Ninh Thuan province, a smallest province located in Southest central Vietnam, has suffered much due to the climate change and land use change. These change and the factors have driven them are subject to increasing soil erosion and loss of agricultural production. This study examined the linkage of land use change and climate variation with soil erosion and rice productivity. The findings of the study revealed that climate change has affected strongly to every aspect in this study area. Temperature increased 0.030C/year in the study period. Pecipitation seemed to increase, but may appear to be a favorable phenomenon to some extent. High precipitation of rainfalls in the rainy season and poor rainfalls led to severe floods in rainy season and prolonged droughts in dry season. The extreme weather events have put people in uncertain situations. Land use changed significantly in over a decade. Cultivated land and settlement land increased quickly, while forest and abandoned land reduced accordingly. Due to land use and rainfall pattern change, soil erosion occurred severely because of less vegetation cover and high amount of rainfall in rainy season. The study found that soil erosions increased from 1995 to 2005, and occurred mainly in abandoned land and annual crop land. Finally, although rice productivity and rice production were greater than before, but rice production was more fluctuation because of climate variation. Prolonged drought and severe flood were the main factors, affecting rice production. |
