Verified Answer
Which of the following is/are the negative consequences of Sandstorms:...
- Sand and dust storms are common meteorological hazards in arid and semi-arid regions.
- They are usually caused by thunderstorms – or strong pressure gradients associated with cyclones – which increase wind speed over a wide area.
Impacts of Sandstorms:
- Negative:
- Affect the Source of Freshwater:
- Very high dust deposition also occurs in the Himalaya-Hindu Kush mountain range and the Tibetan Plateau, the so-called ‘third pole’ that are the sources for fresh water for more than 1.3 billion people in Asia.
- Increases Melting of Ice:
- The deposition of dust on glaciers induces a warming effect, increasing the melting of ice, with direct and indirect impacts on society through numerous issues, including food security, energy production, agriculture, water stress and flood regimes. Hence, statement 2 is correct.
- On Farmland:
- Dust deposition impacted large portions of farmland in Turkmenistan, Pakistan and Uzbekistan.
- Much of this dust is characterised by high salt content, making it toxic for plants.
- It reduces yield, posing a significant threat to the production of irrigated cotton and other crops. Hence, statement 1 is correct.
- Dust deposition impacted large portions of farmland in Turkmenistan, Pakistan and Uzbekistan.
- Affect the Source of Freshwater:
- Positive:
- They can increase the nutrient content in the areas of deposition and benefit vegetation.
- Dust deposited on water bodies can alter their chemical characteristics, triggering both positive as well as adverse outcomes.
- Dust particles that carry iron can enrich parts of oceans, improving the phytoplankton balance and impacting marine food webs. Hence, statement 3 is not correct.
- Hence, option B is correct.
