According to Indian forest policy, what percentage of the land area should be under forest cover?

  1. 11%

  2. 22%

  3. 30%

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In India 6, 77,088 square kilometer of land is under forest cover. The figure was 30 percent at the beginning of 20th century.  

As per World Bank estimates the forest cover in India was 22 percent in the year 2000 and 23 percent in 2010. 
The present forest cover is quite small as compared to optimum of 33 percent according to National Forest Policy, 1988.
Since the 1952 NFP (National Forest Policy in India), there has been an advocacy for 33% forest cover with a 60% forest cover in mountainous and hilly regions.

  • Groundwater - water found in shallow aquifers beneath the earth's surface. This water is generally found at depths up to around 2,000 feet deep.
  • Precipitation: It is nothing but the rain water which is an important source of fresh water. In fact it is the purest natural source of fresh water.

  4. (i) - Rajasthan; (ii) - Meghalaya; (iii) - Karanataka and Maharashtra
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

(i) In Meghalaya sacred groves represent a long tradition of environmental conservation based on indigenous knowledge by the tribal communities. They are among the few least disturbed forest patches which are serving as the natural treasure house of biodiversity and a refuge for a large number of endemic, endangered and rare taxa. The general term for sacred groves in the Khasi Hills is 'Khlaw Kyntang' or 'Law Kyntang' or 'Law Lyngdoh' while in the Jaintia Hills it is called 'Khloo Blai'. The sacred groves in the Khasi Hills and Jaintia Hills District are fundamentally based on the traditional religious belief of the tribals i.e., Khasis and Pnars, which is called Seng Khasi and Niam Tre respectively.

(ii) Sacred Groves are found from the western part of Rajasthan to the east of the Aravalli range. These groves are known under various names in Rajasthan as sacred groves (deora, malvan, deorai, rakhat bani, oran, etc.), sacred corridors (deo ghats), temple forests (mandir van) and sacred gardens (baugh). Brandis, as early as 1887, gave initial information on sacred groves of Aravallis. He wrote, 'though very few papers have been published on sacred groves, this does not mean that such areas do not abound in India'. 
(iii) Western Ghats also known as Sahyadri (Benevolent Mountains) is a mountain range that runs parallel to the western coast of the Indian peninsula. Forest clearance was inevitable for farming and yet, there was an overwhelming belief in the sacredness of the woods.  They were important tracts of pre-colonial forest conservation in the Western Ghats. Myriad relics of such groves, exist even today all over the Western Ghats. They may be called Devrai in Maharashtra, Devarkadu in Kodagu and Kavu in Kerala and Tamil Nadu, these forests in pre-colonial landscape, served many functions like the conservation of biodiversity and watershed, moderation of climate and promoted varied wildlife.
So the correct option is ' (i) Meghalaya, (ii) Rajasthan (iii) Karnataka and Maharashtra'.
