What is appropriate technology for desertification?
Appropriate technology means using cheap, sustainable and available materials that local people can use. Stone lines (or bunds) are an example of appropriate technology. This involves building lines of stones along contours (area of land that is the same height).
How are planting pits appropriate technology?
It is a technology that is low cost and requires skills that can be quickly learned. Planting pits are also used to hold more water around the plant and homemade compost is used to provide a fertility boost for the soil.
What are the control of desertification?
1. Afforestation and planting of soil binding grasses can check soil erosion, floods and water logging. 2. Crop rotation and mixed cropping improve the fertility of the soil.
What is the most effective way to protect drylands from desertification?
6.2 What actions can be taken to prevent desertification?
- 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.
What is a type of appropriate technology that can be used for water treatment?
Appropriate technology options in water treatment include both community-scale and household-scale point-of-use (POU) designs. The most reliable way to kill microbial pathogenic agents is to heat water to a rolling boil.
What is appropriate technology geography?
Appropriate technology is one that is suited to the needs, skills, resources, wealth and knowledge of the people who live in a local area, for the environment in which they live.
Why is reducing desertification important?
In Africa and other countries largely dependant on agricultural production, desertification can reduce agricultural yields and make them much more unpredictable. It therefore affects food security of those living in affected areas.
What causes desertification and what are the best way of controlling this?
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.
How can we reduce land degradation?
Prevention and Control Measures for Land Degradation:
- Strip farming: It is & practice in which cultivated crops are sown in alternative strips to prevent water movement.
- Crop Rotation:
- Ridge and Furrow Formation:
- Construction of Dams:
- Contour Farming:
How is desertification prevented and rehabilitated?
Avoid driving off road in a motor vehicle. Do not make bonfires or barbecues or throw waste in nature. Regarding the overexploitation of aquifers: consume seasonal and local products, which, in general, require less water consumption. In many places, aquifers are plan B for household supply in the event of a drought.
What are the causes effects and control measures of desertification?
Various Causes of Desertification
- Overgrazing.
- Deforestation.
- Farming Practices.
- Excessive Use of Fertilizers and Pesticides.
- Overdrafting of groundwater.
- Urbanization and Other Types of Land Development.
- Climate Change.
- Stripping the Land of Resources.
What are the strategies used to reduce the risk of desertification?
Strategies used to reduce the risk of desertification – water and soil management, tree planting and use of appropriate technology. There are many different strategies for reducing the risk of desertification. This includes water management, tree planting, soil management and using appropriate technology.
How is technology used to manage water supplies in the desert?
This is an example of using appropriate technology to manage water supplies in the desert environment. Magic stones (or bunds) are circles of stones placed on the ground to hold water on the soil rather than letting it run quickly over the surface.
How to prevent desertification in the dry subhumid zone?
In the dry subhumid and semiarid zones, conditions equally favor pastoral and cropping land use. Rather than competitively excluding each other, a tighter cultural and economic integration between the two livelihoods can prevent desertification.
How can we restore and rehabilitate desertified drylands?
Effective restoration and rehabilitation of desertified drylands require a combination of policies and technologies and the close involvement of local communities. Examples of actions to restore and rehabilitate ecosystems include: planting trees.
