In addition, surface and groundwater supplies may decline during drought, affecting water availability and increasing costs to access water for crop or forage irrigation and watering livestock. With a return to normal precipitation, soil moisture typically recovers long before surface and groundwater supplies are replenished.
What are the effects of drought?
The most dangerous effects of drought with respect to biodiversity are as follows: domestic fauna and wildlife, with those who are kept in very bad conditions;migratory birds from increasingly endangered habitats to remnant wetlands;flora, especially where some species are endangered;another environmental impact of drought is that some waterways, which were previously permanent, but lately have become intermittent.

A common query we ran across in our research was “What is the impact of drought on agriculture?”.
Drought can also contribute to insect outbreaks, increases in wildfire and altered rates of carbon, nutrient, and water cycling—all of which can impact agricultural production, critical ecosystem functions that underpin agricultural systems, and the livelihoods and health of farming communities. Drought in your area?
Plant responses to drought stressAltered root architecture to prevent water loss through transpiration, increased water influx into roots. Increased root to shoot ratio, leaf senescence Stomatal closing to prevent water loss. Increased adaptivity of the plants, seed dormancy Inhibition of stimulatory activity of some phytohormones, and more items.
So, what are the effects of drought and floods in Africa?
More recently, the combined influence of drought, floods, economic instability, and HIV/AIDS threatened the food security of millions in southern Africa (WFP, 2002). At a national level, drought ripples across sectors and impacts on a range of activities.
How did the drought affect the Great Plains?
The drought affected the production of livestock and field crops such as wheat, corn, and soybean production in the Great Plains and Midwest and accounted for $14.5 billion in loss payments by the federal crop insurance program.
