2. Land use data is not available for the whole country because most of the north - east states except Assam has not been done fully. In some areas of Jammu and Kashmir occupied by Pakistan and China have also not been surveyed. It is only surveyed for 93% of the total geographical area.

4.

NSA - Net sown area is the area sown in an agricultural year plus net sown area is known as gross cropped area.

Punjab and Haryana have more NSA

6.

• In states like Jharkhand,

Chhattisgarh, Madhya Pradesh and Orissa deforestation due to mining have caused severe land degradation.

• In the states of Punjab, Haryana, western Uttar Pradesh, over irrigation is responsible for land degradation due to water logging leading to increase in salinity and alkalanity in the soil.

Answer - 6 th after attachment↓

$\maltese \pmb{\bold{\: lets \: know \: briefly : -} }$

$\qquad \: \qquad \: \underline{\pmb{ \sf{droughts}}}$

The increase in the concentration of carbondioxide and green house gases like methane , Nitrogen oxide , chloroflurocarbon etc are responsible for increasing temperature on Earth . These gases traps the Earth's heat and cause Global warming which affects the soil with erosion and devoid of vegetative cover occurs will not retain moisture for so long . Hence there would be Droughts and will cause land degradation .

$\qquad \: \qquad \: \underline{\pmb{ \sf{floods}}}$

Rising temperature will lead to the melting of glaciers which will form natural lakes between the mounds of debris and rocks that are left behind by the sliding if glaciers .This means that the glacial lakes will be fled with water from the melting of ice faster than the rare at which that can be drained , this making glacier lakes flood frequently and will lead to land degradation .

$\rm \overbrace {but \: the \: major \: cause \: of \: land \: degradation \: is \: pollution }$

As Air pollution leads Global warming

And because of Global warming Floods and droughts occur .
