How can desertification be managed?

Desertification can be reduced by adopting the following strategies: Planting more trees – the roots of trees hold the soil together and help to reduce soil erosion from wind and rain. Water management – water can be stored in earth dams in the wet season and used to irrigate crops during the dry season.

What are the causes and consequences of desertification?

Overgrazing is the major cause of desertification worldwide. Other factors that cause desertification include urbanization, climate change, overuse of groundwater, deforestation, natural disasters, and tillage practices in agriculture that make soils more vulnerable to wind.

What are the signs of a drought?

Signs of Drought Stress in Trees

• Temporary Wilting. Wilting and drooping leaves will occur during the day.
• Permanent Wilting. As droughts progress, leaves will remain wilted even in the early morning.
• Yellowing Leaves.
• Leaf Scorch.
• Defoliating Trees.
• Bark Cracks.

What are the management of drought?

Drought mitigation measures would include establishing comprehensive early-warning and delivery systems; improved seasonal forecasts; increased emphasis on water conservation (demand reduction); increased or augmented water supplies through greater utilization of groundwater resources, water reutilization, and …

Can plants recover from drought?

Plants have a better chance of surviving drought if they were healthy, vigorous, and mulched before the drought. Once the drought is over, it’s time to assess the damage and take steps to get plants back into shape.

Whats does drought mean?

As a result, the climatological community has defined four types of drought: 1) meteorological drought, 2) hydrological drought, 3) agricultural drought, and 4) socioeconomic drought. Meteorological drought happens when dry weather patterns dominate an area.

What are the management strategies to prevent the effects of droughts?

One strategy is to hold surface water in reservoirs until it is needed. Another strategy is to use new farming practices that require less water. Third, some people suggest that we can avoid drought with cloud seeding—sprinkling small particles into clouds in order to make it rain.

Where do droughts occur?

This can make chronic respiratory illnesses worse and increase the risk for respiratory infections like bronchitis and pneumonia.

How is Drought measured?

The Palmer Z-Index measures short-term drought on a monthly scale. The Palmer Crop Moisture Index (CMI) measures short-term drought on a weekly scale and is used to quantify drought’s impacts on agriculture during the growing season.

Who is affected by droughts?

Drought also affects the environment in many different ways. 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.

What is the longest drought ever recorded?

What is drought write in your own words?

Drought is a continuous period of dry weather, when an area gets less than its normal amount of rain, over months or even years.
