Study Notes

Drought Background

  • Drought is a natural hazard, increasingly influenced by climate change
  • Rising temperatures and changing rainfall patterns are significant causes
  • Drought impacts health and global well-being, regional, local, and global levels
  • Four types of drought: hydrologic, agricultural, meteorological, and socioeconomic.
  • Soil moisture deficiency is a major cause of agricultural droughts
  • Machine Learning (ML) can predict drought
  • Early warning and hazard alleviation are crucial for economic and social development

Study Area (Pakistan)

  • Located in South Asia, with diverse topography and climate variations
  • Situated between latitudes 23°30' N–37°30′ N and longitudes 61°E–78°E
  • Characterized by four distinct seasons: winter, spring, summer, and autumn
  • Western and Indian monsoons influence precipitation, with significant variations across the country
  • Mean monthly temperature and precipitation data (1991-2022) show seasonal fluctuations.
  • Agriculture is a major economic sector in Pakistan.
  • Drought is a major recurring hazard, impacting people's lives and livelihoods

Drought in Pakistan

  • Pakistan is highly susceptible to climate change and drought
  • Causes include a temperature rise, reduction in precipitation in arid areas, increases in monsoon regions and accelerated glacial melt
  • Drought and floods are common in certain regions but are closely tied to the weather patterns.
  • Remote sensing and meteorological data are used for drought monitoring and prediction

Drought Monitoring and Prediction

  • Historical data sets for climate characteristics (precipitation, snow cover, relative humidity) are analyzed, along with satellite indicators, to predict drought
  • Machine Learning (ML) techniques are used for efficient drought prediction.
  • Using Remote Sensing and ML techniques are key to better predict drought
  • Existing Drought Indices, like SPEI and RDI, are valuable for drought assessment
