This is PowerPoint presentation about the topic: Drought and desertification. It clearly defines drought and desertification, it's causes, effects as well as how they can be minimised.

1. DROUGHT AND DESERTIFICATION
N MCHUNU

2. DROUGHT

3. • Drought is a long period of low rainfall, which leads to a
shortage of water
• This might have an impact on ecosystems, agriculture and
water supplies
• People and animals are more likely to be affected by drought.

4. CAUSES OF DROUGHT
• Low precipitation over an extended period of time: This lack of
precipitation leads to a water deficit, causing soil moisture levels to
decrease and water sources to deplete.
• High temperatures: Elevated temperatures can intensify drought
conditions. When the temperature arises, it accelerates evaporation
rates from bodies and soil surfaces.
• Increased evaporation: Evaporation is the process by which water
turns into vapor and rises into the atmosphere. It may cause water
bodies, soils, and vegetation to lose more water.

5. IMPACT OF DROUGHT
• Drought may impact negatively farming. The vegetation and
crops need water to grow, drought may damage crops and
vegetation which would make farmers lose much profit.
• Drought results to destruction of ecosystem as there will be
shortage of water for animals to drink which could result to
deaths.

6. WAYS TO MANAGE DROUGHT
• Plantation of drought resistant crops.
• Building of large dams.
• Educating communities about water conservation.

7. DESERTIFICATION

8. • Desertification is the process whereby fertile land becomes
more arid or becomes a desert.
• Desertification is more related to drought as their impacts are
almost the same.
• It is most likely to be concerning the vegetation.

9. CAUSES OF DESERTIFICATION
• Deforestation
• Overgrazing
• Urbanization
• Improper agricultural practices

10. IMPACT OF DESERTIFICATION
• Desertification minimises agriculture which might affect people
who depends on farming for a living.
• Desertification also leads to a destruction of habitats and
ecosystems, leading to a loss of plant and animal species.
• It also results to less food for animals for grazing.

11. WAYS TO DEAL WITH DESERTIFICATION
• Planting more trees.
• Promotion of resistance in lands used for livestock grazing.
• Educating people about the impact of desertification on the
environment.
