Pak Climate Extreme
Announcement

The global warming causes the global climate changes, and Pakistan listed in number eight of the most ten affected countries from 1995-2014 in the world. The natural disasters in response to drought and flood are the most common and frequently occurring hazards in the regions and specifically over Pakistan in a recent couple of century due to environmental, climatic and ecosystem anthropogenic factors. Drought is a complex phenomenon of environmental processes and considered as the stochastic nature of hazards with a prolonged scarcity and dearth character that results from the meager annual precipitation and superficial water contents through impacts on the agricultural, meteorological, hydrological and socio-economic with a potentially significant consequences. Drought is a prolonged event of insufficient rainfall with follow-on extensive damage to crops, resulting in loss of yield. Alike drought, flood is the world’s costliest natural disasters due to extreme climate events under global warming conditions. The soil moisture had a significant role in retains of dry and wet spells in both rain-fed and irrigated conditions and key indicator of drought and flood. The stochastic characterization of drought in the plain of Punjab (Pakistan) was strongly motivated by the fact that the reliance on precipitation data is not sufficient for drought monitoring, taking into account the lack of reliable and complete data, together with proper network information systems, particularly the lower availability of weather-stations in Pakistan.
