How does a drought affect plants and animals?
When conditions are extremely dry, forbs produce fewer stems, flowers and seeds. Usually, they are a significant source of protein for animals that graze on them. However, during a drought, the stems and leaves are less palatable and nutritious.
Why do plants die when there’s a drought?
During drought, there is lack of water and many processes shut down without water, photosynthesis being one of them. Plants cannot photosynthesise sunlight without water. Without photosynthesis, plants they cannot create glucose to support life processes within the plant.
What happen to plants and crops when there is drought?
Plants and animals depend on water, just like people. When a drought occurs, their food supply can shrink and their habitat can be damaged. Sometimes the damage is only temporary and their habitat and food supply return to normal when the drought is over.
How do droughts affect farmers?
The impact of drought The impact of a drought on crop producers is immediate; for livestock producers it is evident later. Intensive livestock producers managed to maintain production during 2015. However, the weakening product-to-feed ratio, driven by the higher maize and soya bean prices, has reduced profit margins.

What are the effects of drought in Limpopo?
Macroeconomic impacts
| Primary impacts | Secondary impacts |
|---|---|
| Increased evapotranspiration | Crop withering and dying |
| More dust and sandstorms | Increased soil erosion; increased air pollution |
| Decreased soil productivity | Desertification and soil degradation (topsoil erosion) |
| Decreased water resources | Lack of water for feeding and drinking |
