Questions Related to damaging the forests

If we uncover half of the forest, covering of the earth, what crisis will be produced at most and at first?

  1. Some species will be extincted

  2. Population and ecological imbalance will rise up

  3. Energy crisis will occur

  4. Rest half forests will maintain this imbalance


Correct Option: A
Explanation:

Forest is the home of many of distinct species and even undiscovered species if the forest is uncovered many of the species lost their natural habitat and become extinct which further leads to the following problem like:

  • Rise in population and ecological balance- The number of producer decreases, the dependent consumers will die out of starvation. This lead to rise in ecological imbalance.
  • Energy crises- Due to the decrease in the number of producers.
  • Imbalance in the forest- As the number of producer decreases, the food chain gets disturbed.
So the correct option is 'Some species will be extinct'.

In which of the following agricultural practices is a part of a forest cleared for cultivation and then moving on to a new part for cultivation?

  1. Monoculture

  2. Mixed farming

  3. Field fallow

  4. Shifting cultivation


Correct Option: D
Explanation:

Shift cultivation is a type of agricultural method in which farmer clears the land by burning forest and cultivate that land for short period of time. Once the soil becomes infertile farmer again clear the another land for cultivation. It is also called as jhum cultivation.

'Jhum' cultivation is also known as

  1. Terrace farming

  2. Tribal farming

  3. Shifting cultivation

  4. Farming on a slope


Correct Option: C
Explanation:

Jhum (Shifting) cultivation is a primitive practice of cultivation in States of North Eastern Hill Region of India and people involved in such cultivation is called Jhumia. The practice involves clearing vegetative/forest cover on land/slopes of hills, drying and burning it before the onset of monsoon and cropping on it thereafter. After harvest, this land is left fallow and vegetative regeneration is allowed on it till the plot becomes reusable for the same purpose in a cycle. Meanwhile, the process is repeated in a new plot designated for Jhum cultivation during next year. Initially, when the Jhum cycle was long and ranged from 20 to 30 years, the process worked well.


So, the correct option is 'Option C'.

Shifting cultivation practised in India is called

  1. Sawani

  2. Jhum

  3. Harhi

  4. All the above


Correct Option: B
Explanation:

Shifting cultivation, also known as the slash and burn agriculture (or Jhum cultivation), is the process of growing crops by first clearing the land of trees and vegetation and burning them thereafter. The burnt soil contains potash which increases the nutrient content of the soil. This burnt land is left for 5-8 years, so as to give the soil the time to regain its fertility . It was practised by the nomads in the north- eastern states of India .

So, the correct answer is 'Jhum'

Taungya is

  1. A method of shifting cultivation

  2. Type of agroforestry practice

  3. Protection forestry

  4. Both A and B


Correct Option: D
Explanation:

Taungya is a system whereby villagers & sometimes forest plantation workers are given the right to cultivate agricultural crops during the early stages of forest plantation establishment 

So, the correct answer is 'Both A and B'

In India, Jhum is practised in

  1. Maharashtra

  2. Madhya Pradesh

  3. North-eastern states

  4. Himachal Pradesh


Correct Option: C
Explanation:

Jhum cultivation, also known as the slash and burn agriculture, is the process of growing crops by first clearing the land of trees and vegetation and burning them thereafter. The burnt soil contains potash which increases the nutrient content of the soil. This burnt land is left for 5-8 years , so as to give the soil the time to regain its fertility . It was practised by the nomads in the north- eastern states of India .

So, the correct answer is 'North-eastern states'

The type of pollution which is found the third most is

  1. Land or landscape pollution

  2. Controlled tipping

  3. Noise pollution

  4. UV pollution


Correct Option: A
Explanation:

The three main types of pollution are 1. Air Pollution 2. Water Pollution 3. Soil Pollution. Rapid urbanization, with the consequent increase in population and building construction, has resulted in the reduction of land for the wastes to be disposed of.

Every year solid wastes are increasing tremendously all over the world. Several hazardous chemicals and the mountains of wastes are ultimately dumped on the land. For example sources of soil, pollution is 
1. Industrial wastes, 2. Urban wastes, 3. Radioactive pollutants, 4. Agricultural practices, 5. Biological agents, 6. Soil sediments.
So the correct answer is 'Land or landscape pollution'.

Mine spoil is

  1. Wastes from mines

  2. Wastes from mine processing

  3. Land degraded by mining

  4. Both A and B


Correct Option: C
Explanation:
A spoil tip is a pile built of accumulated spoil – the overburden or other waste rock removed during coal and ore mining.
So, the correct answer is 'land degraded by mining'

Taungya is practice of

  1. Shifting cultivation

  2. Agroforestry

  3. Production forestry

  4. Both A and B


Correct Option: D
Explanation:

Taungya is practice of shifting cultivation and agroforestry. If is a form of agroforestry system. In this, the villagers are given the right to cultivate short term crops during the early stages of forest plantation establishment. This is continued until trees shade crops due to canopy closure. This is done to utilize the land, control weeds, generate extra income.

Thus, the correct answer is 'Both A and B.'

An agroforestry, taungya consists of

  1. Growing crops in between rows of trees

  2. Growing crops after removal of trees

  3. Growing trees on degraded soils

  4. All of the above


Correct Option: A
Explanation:

Taungya system is a form of agroforestry system in which short term crops are grown in the early years of the plantation of a woody perennials species in order to utilize the land, control weeds, reduce establishment costs, generate early income and stimulate the development of the woody perennial species.

So, the correct answer is 'Growing crops in between rows of trees'
