Desertification may
alter the living conditions of the local flora and fauna that makes it impossible for animals and plants to sustain their populations
. After desertification, regions suffer from water shortages due to climate change and animals may suffer and die since water is vital for all life on our planet.
What are 7 consequences of desertification?
In addition, the delegates considered the varied consequences of desertification, such as
crop failures or decreased yields in rain-fed farmland, the loss of perennial plant cover and thus loss of forage for livestock, reduced woody biomass and thus scarcity of fuelwood and building materials, a decrease in potable
…
What are some long term effects of desertification?
“The [result is]
declines in crop and livestock productivity, loss of biodiversity, increasing chances of wildfires in certain areas
. Naturally, these will have negative impacts on food security and livelihoods, especially in developing countries.”
What are the consequences of desertification Class 8?
3)
Deforestation will cause soil erosion making soil infertile
and lead to desertification:The roots of trees bind the particles of top soil together. Due to this binding of soil particles,the wind and water are not able to carry away the top soil due to which the top soil does not become loose quickly.
What are the effects of desertification on people and the environment?
Desertification, an extreme form of land degradation, is a global phenomenon that is influenced by and has
an impact on climate change and biodiversity loss
. Land degradation causes a decline in land productivity and is therefore likely to lead to increased levels of poverty.
What are the negative impacts of desertification?
The moisture content in the area decreases and soil becomes more vulnerable to both wind erosion and water ero- sion, resulting in problems like decreased water quality,
increased sediment deposits, flooding, and dust storms
.
What are the disadvantages of desertification?
- Farming becomes next to impossible. If an area becomes a desert, then it’s almost impossible to grow substantial crops there without special technologies. …
- Decrease in Crop Yields. …
- Hunger. …
- Flooding. …
- Poor Water Quality. …
- Overpopulation. …
- Poverty. …
- Biodiversity Loss.
What are the 5 consequences of desertification?
outside the immediately affected
areas–downstream flooding, reduced water quality, sedimentation in rivers and lakes, silt sediment in reservoirs and navigation channels, dust storms and sand drifting
; Consequences of desertification (Cont.)
What is the major cause of desertification?
‘Climatic variations’ and ‘Human activities’
can be regarded as the two main causes of desertification. removal of the natural vegetation cover(by taking too much fuel wood), agricultural activities in the vulnerable ecosystems of arid and semi-arid areas, which are thus strained beyond their capacity.
What can we do to stop 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.
What are 3 causes of desertification?
Human activities that contribute to desertification include the
expansion and intensive use of agricultural lands, poor irrigation practices, deforestation, and overgrazing
. These unsustainable land uses place enormous pressure on the land by altering its soil chemistry and hydrology.
People are forced to migrate, with many people – young men in particular
, leaving to work in cities and towns. This puts pressure on already limited urban resources. Disputes occur over land between herdsmen and farmers. Food shortages lead to malnutrition and famine, eg in Ethiopia.
What are the causes and consequences of the deforestation?
- Increase in temperature and Global Warming.
- Increase in pollution.
- Soil erosion.
- Loss of habitat of wild animals.
- Shortage of food and forest produce.
- Leads to natural calamities like floods and droughts.
- Disruption of water cycle.
How does desertification impact my life?
His life has become more complicated because of desertification. … Desertification is the
persistent degradation of dry land ecosystems by human activities and by climate change
. It translates into scarcer rains and decreasing soil quality, which leads to less grazing for livestock and lower crop yield.
What are 5 causes of drought?
- 1) Land and water temperatures cause drought. …
- 2) Air circulation and weather patterns also cause drought. …
- 3) Soil moisture levels also contribute to drought. …
- 4) Drought can also be a supply and demand of water issue.
How does desertification affect the economy?
The impact of desertification on the socio-economic life of rural households leads to
reduction in crop and animal production
, as well as causing, livestock deaths and rise in the prices of foodstuffs.
