2.2. Land Use

Land is among the most important natural resources. It covers only about thirty per cent of the total area of the earth’s surface and all parts of this small percentage are not habitable.

Land is a crucial resource for humans and all living organisms. It only occupies about 30% of Earth's surface. However, not all land can be utilized for living or farming; some areas are too rough or dry.

Think of the Earth as a giant cake. If only a small slice represents land, then not all of that slice is suitable for eating. Some might be burnt, while others could be hard to cut through; similarly, parts of land can be unsuitable for habitation.

The uneven distribution of population in different parts of the world is mainly due to varied characteristics of land and climate. The rugged topography, steep slopes of the mountains, low-lying areas susceptible to water logging, desert areas, thick forested areas are normally sparsely populated or uninhabited.

Population is not distributed evenly because people tend to settle in places that have favorable conditions for living and farming. Rugged or difficult terrains and harsh climates lead to fewer people living there.

Imagine you have a group of friends planning a picnic. Would you choose a rocky, steep hill or a flat, grassy park? Most would opt for the park because it's easier and more comfortable, just like how people prefer living in suitable land.

Land is used for different purposes such as agriculture, forestry, mining, building houses, roads and setting up of industries. This is commonly termed as Land use.

Land serves multiple functions, including agriculture (growing crops), forestry (wood production), mining (extracting minerals) and urban development (constructing buildings and roads). This variety of uses is referred to as land use.

Consider land like a big toolbox. Each tool has a specific job: some tools help you build something (urban development), others help you grow something (agriculture), and some are for digging (mining). Each tool serves a purpose.

The use of land is determined by physical factors such as topography, soil, climate, minerals and availability of water. Human factors such as population and technology are also important determinants of land use pattern.

Physical features of land (like hills or rivers) and conditions like climate and soil type dictate how the land is used. Moreover, human activities, including population density and technological advancements, also shape land use.

Think of baking a cake. The type of cake you make (chocolate, vanilla, etc.) depends on the ingredients (physical factors) you have on hand. Likewise, land use is dependent on what resources and people are available.

Land can also be classified on the basis of ownership as – private land and community land. Private land is owned by individuals whereas, community land is owned by the community for common uses like collection of fodder, fruits, nuts or medicinal herbs.

Land ownership can be categorized mainly into two types: private land, which is owned by individuals or families, and community land, which is collectively owned by a group and used for common benefits.

Consider sharing a playground. It can be thought of as community land where everyone plays together, while your backyard is private land where only your family has access and control.

The vast changes in the land use pattern also reflect the cultural changes in our society. Land degradation, landslides, soil erosion, desertification are the major threats to the environment because of the expansion of agriculture and construction activities.

As society and culture evolve, the way we use land changes. However, this can sometimes lead to negative consequences like land degradation where the quality of land decreases, making it less productive.

Imagine a beautiful garden that is suddenly turned into a parking lot. While it may serve a new purpose, the natural beauty and productivity of the garden are lost, similar to how changing land use can harm the environment.

Therefore, the present rate of degradation of land must be checked. Afforestation, land reclamation, regulated use of chemical pesticides and fertilisers and checks on overgrazing are some of the common methods used to conserve land resources.

To combat land degradation, various strategies must be employed, such as planting trees (afforestation), restoring damaged land (land reclamation), careful use of chemicals, and controlling livestock grazing.

Think of caring for a plant. You water it, ensure it gets sunlight, and sometimes, you even remove weeds. Similarly, conserving land resources requires ongoing care and management.
