Monitoring agricultural and economic drought: the Australian Agricultural Drought Indicators (AADI)

Natural Hazards and Earth System Sciences
Abstract. Drought events can have significant agricultural and economic impacts, and in many parts of the world their intensity appears to be increasing with climate change. However, drought measurement remains a highly contested space, with a multitude of indicators across both research and operational settings.

Assessment of basin-wise future agricultural drought status across India under changing climate

Journal of Water and Climate Change, 2021
Most of the existing studies on meteorological drought suggest more intense and frequent drought events due to changing climate. However, basin-scale assessment of future agricultural drought is lacking due to many reasons.
