Introduction:
In arid and semi-arid areas, where water availability is limited and the soil is often poor in quality, it is important to find suitable land uses that can maximize the utilization of these resources. Converting lands unsuitable for cultivation into pastures can be a beneficial option in such areas.

Benefits of Converting Unsuitable Lands into Pastures:
1. Utilization of water resources: Pastures require less water compared to crops, making them a more suitable option in arid and semi-arid areas. The limited water availability can be effectively utilized for grazing animals, ensuring sustainable use of water resources.

2. Soil conservation: The soil in arid and semi-arid areas is often prone to erosion and degradation. By converting unsuitable lands into pastures, the vegetation cover and root systems of grasses and forage crops can help prevent soil erosion and improve soil quality over time.

3. Livestock rearing: Pastures provide ample grazing opportunities for livestock, allowing for the development of livestock-based economies in these regions. Livestock farming can provide a sustainable source of income for the local population and contribute to economic growth.

4. Biodiversity preservation: Converting unsuitable lands into pastures can help preserve biodiversity in arid and semi-arid areas. The establishment of diverse grasses and forage crops can attract various animal species, contributing to the conservation of local flora and fauna.

5. Carbon sequestration: Vegetation in pastures plays a crucial role in carbon sequestration, helping to mitigate climate change. The roots of grasses and forage crops store carbon in the soil, reducing greenhouse gas emissions and enhancing the overall carbon balance in the ecosystem.

Conclusion:
In conclusion, converting lands unsuitable for cultivation into pastures in arid and semi-arid areas can provide numerous benefits. It allows for the efficient use of limited water resources, helps prevent soil erosion, supports livestock rearing and local economies, preserves biodiversity, and contributes to carbon sequestration. Therefore, converting unsuitable lands into pastures is a suitable and sustainable option for maximizing the potential of these areas.

Direction: Read the case study given below and answer any three of the questions that follow.If soil erosion and exhaustion are caused by humans; by corollary, they can also be prevented by humans. Nature has its own laws of maintaining balance. Nature offers enough opportunities for humans to develop their economy without disturbing the ecological balance. Soil conservation is a methodology to maintain soil fertility, prevent soil erosion and exhaustion, and improve the degraded condition of the soil. Soil erosion is essentially aggravated by faulty practices. The first step in any rational solution is to check open cultivable lands on slopes from farming. Lands with a slope gradient of 15-25 per cent should not be used or cultivation. If at all the land is to be used for agriculture, terraces should carefully be made. Over-grazing and shifting cultivation in many parts of India have affected the natural cover of land and given rise to extensive erosion. It should be regulated and controlled by educating villagers about the consequences. Contour bunding, Contour terracing, regulated forestry, controlled grazing, over cropping, mixed farming and crop rotation are some of the remedial measures which are often adopted to reduce soil erosion. Efforts should be made to prevent gully erosion and control their formation. Finger gullies can be eliminated by terracing. In bigger gullies, the erosive velocity of water may be reduced by constructing a series of check dams. Special attention should be made to control headward extension of gullies. This can be done by gully plugging, terracing or by planting cover vegetation. In arid and semi-arid areas, efforts should be made to protect cultivable lands from encroachment by sand dunes through developing shelter belts of trees and agro -forestry. Lands not suitable for cultivation should be converted into pastures for grazing.

Directions: Read the following passage carefully:The pressure on land resources is increasing with more demand for food production. This has forced farmers to develop land for agriculture production and adopt intensive and unsustainable land-use techniques that can cause high levels of soil erosion. Increasing pressures of urbanisation and industrialisation and anthropogenic activities such as building of roads, dams, construction activities are also increasing the rate of erosion of the soil in India. The different kinds and increasing extent of erosion contribute to rapid conversion of cultivable lands into wastelands. For example, recent evidence shows that about 20% of the total geographical area of the country has been converted into wastelands.Since the causes of soil erosion differ from one area to the other, different methods such as contour tillage, contour bunding, construction of check dams, terrace farming etc are used to prevent erosion and improve soil quality.Source: Indiawaterportal.org, Aarti Kelkar Khambete, 2021.Q.Which category of land use will increase due to soil erosion?
