“…Droughts are particularly devastating in Pakistan when they occur during crop growing seasons . Therefore, the characterization of drought hazards during different climatic and cropping seasons is essential for the development of effective adaptation and coping strategies (Wang et al 2012). The drought maps prepared in the present study can be used to identify drought prone areas during different climatic and crop growing seasons.…”

“…Drought is a multivariate phenomenon, characterized by its frequency and severity (Reddy and Ganguli 2013). Asian countries have seen a marked increase in the frequency and severity of droughts in recent years (Wang et al 2012). According to a recent Intergovernmental Panel on Climate Change (IPCC) study, the production of rice, maize, and wheat in many parts of Asia has declined over recent decades due to increasing water stress attributed to a combination of increasing temperatures, the increasing frequency of El Niño events, and a reduction in the number of rainy days (Bates et al 2008).…”

Droughts are usually destructive when they coincide with crop growing season. Cross-seasonal drought characterization can better inform drought mitigation efforts. The present study relies on precipitation data from the Global Precipitation Climatology Centre to reconstruct historical droughts during different climatic seasons in Balochistan province, Pakistan. We identified seasonal drought events based on the standardized precipitation index for each season. The distribution of reconstructed drought events was analyzed to determine their seasonality and to calculate their return periods. Using these return periods, we constructed seasonal drought maps. The study revealed that early winter droughts are frequent in the north of Balochistan, where the return periods of moderate, severe, and extreme droughts are 7, 21, and 55 years, respectively. Severe and extreme late winter droughts are more frequent in the upper north, with return periods of 16 and 35 years, respectively. Early summer droughts occur more frequently in the east, returning every 8, 20, and 60 years; late summer droughts occur in the northeast, with moderate, severe, and extreme droughts returning every 8, 22, and 65 years, respectively. Rabi droughts are more frequently in the central and northeaster regions of Balochistan, while more severe kharif droughts occur primarily in the eastern regions. These seasonal droughts were found to be positively correlated with variations in the seasonal rainfall throughout the study area. The findings of this study contribute to our understanding of seasonal drought characteristics and help to inform drought mitigation planning.

“…In its simplest form, the impact of a drought can be measured as the negative deviation in crop yield in a drought year from its previous normal or historical trend (Xiao-jun et al, 2012). The 'value at risk' approach has also been used to estimate probable loss from extreme climatic events, where the loss is measured as the product of severity and frequency of the event, value of assets exposed to the event and their vulnerability to the event (see, ECA, 2009).…”

This study assesses the impacts of recent climate changes on drought-affected areas and the occurrence of droughts during different cropping seasons of Nigeria using the standardized precipitation evapotranspiration index (SPEI). The crop growing seasons are considered because the droughts for those periods are more destructive to national agricultural production. The Mann–Kendall test and binary logistic regression were used to quantify the trends in drought-affected areas and the occurrence of crop droughts with different areal extents, respectively. Gauge-based gridded rainfall and temperature data for the period 1961–2010 with spatial resolutions of 0.5° were used. Results showed an increase in the areal extent of droughts during some of the cropping seasons. The occurrences of droughts, particularly moderate droughts with smaller areal extents, were found to increase for all of the seasons. The SPEI values calculated decreased mostly in the regions where rainfall was decreasing. That is, the recent changes in climate were responsible for the increase in the occurrences of droughts with smaller areal extents. These trends in climate indicate that the occurrence of larger areal extent droughts may happen more frequently in Nigeria in the future.
