Answer 1

(1) 6Conservation of resources is essential because some resources like minerals are non renewable and need conservation for future generations. Conservation is a judicious and careful management of resources by man as improper and overuse can deplete them leading to many ecological problems.
Three methods of soil conservation are:
(i) Terrace farming : Cutting of hilly areas into steps to reduce the flow of running water.
(ii) Strip cropping : Growing of crops in long strips.
(iii) Planting of shelter belts : Shrubs and trees are planted along fields to control the force of wind.

(3)(a) Mining : Mining sites are abandoned after excavation work is complete leaving deep scars in states such as Jharkhand, Chhattisgarh, Madhya Pradesh and Odisha. Deforestation due to mining has caused severe land degradation.
(b) Over irrigation : Over irrigation in the states of Punjab, Haryana, Western Uttar Pradesh, has caused water logging and increase in salinity of soil.
(c) Overgrazing : Overgrazing in states such as Gujarat, Rajasthan, Madhya Pradesh and Maharashtra is a huge cause due to cattle population.
(d) Industries : Mineral processing industry like grinding of limestone for cement industry and calcite and soapstone for ceramic industry generate huge quantity of dust, this retards the process of infiltration of water into the soil.
(e) Industrial Waste : Industrial effluents also have become a major source of land degradation.

(4)Resource Planning. Resource planning refers to the strategy for planned and judicious utilisation of resources. Resource planning is essential for sustainable existence of all forms of life.
Resource planning is essential for India as there is enormous diversity in the availability of resources. For example the state of Rajasthan has vast potential for the development of solar and wind energy but is deficient in water resources.
The cold desert of Ladakh has rich cultural heritage but is deficient in water and some strategic minerals.
The state of Arunachal Pradesh has abundance of water resources but lacks infrastructure which shows mere availability of resources in the absence of technology and institutions hinders development.
This shows that the resource planning is needed at the national, regional, state and local levels for balanced development of a country
