“…Drought is a phenomenon in which the precipitation is signi cantly less than the multi-year average precipitation during a certain period (Dracup et al, 1980). When the water supply is insu cient to meet the water needs of the population and causes economic losses and human casualties, which is called a drought disaster (Bi et al, 2021). Drought disasters pose a serious threat to climate-sensitive economic sectors, especially the agricultural sector (Simelton et al, 2012.…”

Shandong Province, the main grain-producing area in China, has ranked rst in China in terms of total agricultural output value for many years. However, droughts with high frequency and long duration have been hindering local agricultural production. This paper aims to assess the risk of drought disaster in Shandong Province. Based on the natural disaster system theory, an agricultural drought disaster risk assessment model is developed. This model is applied to assess the agricultural drought hazard, exposure, vulnerability, emergency response and recovery capability, and comprehensive agricultural drought disaster risk year by year from 2012 to 2019. The results show that: (1) There is an aridity trend in Shandong Province. The interannual variation of drought hazard is obvious, and the areas with high drought hazard levels are largely located in the eastern part. (2) Agricultural exposure and vulnerability are mainly concentrated in the western part of Shandong Province. With the decrease in the proportion of the rural population, there is a slight downward trend of agricultural exposure. (3) The interannual variation of emergency response and recovery capability in Shandong Province is relatively stable. Agricultural insurance premiums in all regions have a clear upward trend, which is helpful for disaster risk reduction. (4) Rizhao has been in a high-risk area, moreover, Binzhou, Dezhou, and Liaocheng have gradually become high-risk areas in recent years. The interannual variation characteristics and spatial zoning of agricultural drought risk are explored, it is instructive for risk decision-makers to better develop drought response measures and improve drought resilience.

Climate change has made The Gambia vulnerable to drought hazard. Variability and negative trends in rainfall quantity and mid-season dry spells mainly attributed to the impacts of climate change. The inadequacy in hydrometeorological information puts the agricultural sector at a high risk which employs over 70% of the population. The aim of this study was to establish the intensity and spatiotemporal pattern of drought in The Gambia from 2000-2020 using multiple drought indices. Rainfall data, satellite images, and government policy documents were analyzed to determine the state of drought in The Gambia. Rainfall data, using Standardized Precipitation Index (SPI) and Precipitation Anomaly Percentage (PAP) were calculated and interpolated, and satellite images were processed using Vegetation Condition Index (VCI) to determine drought intensity and spatial distribution. The ndings revealed that drought exists in The Gambia at moderate levels of SPI values (-1.00 to -1.49), (35% of PAP), and VCI of no drought intensity of more than 35%. The most drought prone areas in The Gambia are North Bank Region and Eastern parts of country in both north and south of the Gambia River banks. Recommendations of adaptation practice both on-farm and off-farm such as damming and economic diversi cation was drawn from other parts of the world, to reduce the negative effects of drought hazard in The Gambia.
