How can we save land from desertification?
Preventive actions include:
- Integrating land and water management to protect soils from erosion, salinization, and other forms of degradation.
- Protecting the vegetative cover, which can be a major instrument for soil conservation against wind and water erosion.
How can we prevent desert?
Strategies to reduce desertification
- Planting more trees – the roots of trees hold the soil together and help to reduce soil erosion from wind and rain.
- Improving the quality of the soil – this can be managed by encouraging people to reduce the number of grazing animals they have and grow crops instead.
How can we solve desert problems?
Solutions. We can more efficiently use existing water resources and better control salinization to improve arid lands, find new ways to rotate crops to protect the fragile soil, and plant sand-fixing bushes and trees.
How can we prevent desert encroachment?
Can you reverse a desert?
If sufficient water for irrigation is at hand, any hot, cold, sandy or rocky desert can be greened. Water can be made available through saving, reuse, rainwater harvesting, desalination, or direct use of seawater for salt-loving plants.
Where are people losing land to desertification?
Like Iran, Mongolia and Pakistan, deserts are expanding in China. The Tengger Desert, located on the southern edge of the Gobi Desert, has grown at an annual rate of more than 1,350 square miles. Many villages have been lost. In Syria, sand dunes are encroaching on agricultural lands and mountain slopes of Nepal are getting eroded.
How can we prevent or reverse desertification and save?
Despite of looking horribly dry and damaged, natural dry-lands will turn green and lush again; soils will mend; water creeks will start flowing and wells will refill with water. While lands degraded to the point of desertification, they’ll remain lifeless. The only effect rainwater will have on them will be erosion and flooding.
How much does it cost to turn desert sand into farmland?
“I can double the farming area using the same amount of water I was using before,” says Faisal. The cost of treatment per hectare (2.4 acres) of desert varies from $1,800-$9,500 (£1,300-£6,900) depending upon the size of the project – which currently makes it too expensive for most farmers.
How is desert control going to help farmers?
Desert Control says initially it will target municipal governments and commercial growers, but eventually would like to make the cost accessible to all growers. “This is a great game changer” for farmers in arid areas, says Kristian.
