Q.Study the following source and answer the Question No. 15 to 17. A Case Study Jhabua district is located in the westernmost agro-climatic zone in Madhya Pradesh. It is, in fact, one of the five most backward districts of the country. It is characterized by high concentration of tribal population (mostly Bhils). The people suffer due to poverty which has been accentuated by the high rate of resource degradation, both forest and land. The watershed management programmes funded by both the ministries of “Rural Development” and “Agriculture”, Government of India, have been successfully implemented in Jhabua district which has gone a long way in preventing land degradation and improving soil quality. Watershed Management Programmes acknowledge the linkage between land, water and vegetation and attempts to improve livelihoods of people through natural resource management and community participation. In the past five years, the programmes funded by the Ministry of Rural Development alone (implemented by Rajiv Gandhi Mission for Watershed Management) has treated 20 percent of the total area under Jhabua district. Which statement is NOT correct regarding Jhabua ? (A) Jhabua is tribal concentrated district. (B) Poverty has increased in the people due to land degradation. (C) State government has provided money to implement watershed management programme. (D) Watershed management programme has outstanding contribution in land treatment.

Land use classification is a vital exercise for a country like India, where agriculture, forestry, and urban expansion compete for every hectare. Among the many categories of land, "wastelands" hold special significance — these are degraded or underutilised lands that could potentially be brought under cultivation, afforestation, or other productive use. But who actually maps and classifies these wastelands?

The answer lies with the National Remote Sensing Centre (NRSC), headquartered in Hyderabad. NRSC is the primary government agency responsible for remote sensing data acquisition, processing, and dissemination in India. It operates under the Indian Space Research Organisation (ISRO), but its specific mandate includes large-scale land use and land cover mapping.

NRSC has carried out multiple cycles of wasteland mapping using satellite imagery, most notably through the Wastelands Atlas of India. This atlas, prepared in collaboration with the Department of Land Resources, classifies wastelands into categories such as gullied land, scrubland, waterlogged areas, salt-affected land, and shifting cultivation areas. The classification is done at a very fine scale — often at 1:50,000 or even 1:10,000 — using high-resolution data from satellites like Resourcesat and Cartosat. …

Land use classification helps us understand how different parts of the land are utilised and categorised. Within this framework, "wastelands" refer to land that is currently unproductive or unsuitable for cultivation. These wastelands can arise from natural causes or, significantly, from human activities that degrade the land over time. The statement highlights the latter: wastelands that become unfit for agriculture specifically due to human actions.

Let's examine the given options in this context:

• i. Shifting cultivation area: Shifting cultivation, also known as 'jhum' cultivation in some parts of India, is an agricultural practice where a patch of forest land is cleared, cultivated for a few years until its fertility declines, and then abandoned for a new patch. While it can be sustainable if practiced with long fallow periods, intensive or rapid shifting cultivation without sufficient time for natural regeneration leads to severe deforestation, soil erosion, loss of topsoil, and nutrient depletion. These human-induced changes render the land degraded and unfit for sustained agriculture.

• ii. Coastal plains: Coastal plains are naturally formed geographical features, typically fertile and often extensively used for agriculture due to their flat terrain and proximity to water. While human activities like industrial pollution, excessive groundwater extraction leading to salinisation, or construction can degrade specific parts of coastal plains, the term "coastal plains" itself does not inherently imply land rendered unfit for agriculture by human activities. Many coastal plains remain highly productive agricultural zones.

• iii. Degraded pastures: Pastures are lands used for grazing livestock. When these pastures are subjected to overgrazing – a direct human activity involving the management of livestock – the vegetation cover is excessively removed. This leads to soil compaction, reduced water infiltration, increased soil erosion, and a decline in soil fertility. Such land becomes "degraded" and loses its capacity to support healthy vegetation, making it unfit for productive agriculture or even sustainable grazing. …

Land use classification and demographic terminology form the backbone of understanding how populations interact with territory. When we study population geography, we rely on precise definitions to measure pressure on land, agricultural capacity, and workforce characteristics. Each term captures a different dimension of the human-land relationship.

Physiological density measures how many people depend on each unit of cultivated land. It divides total population by net cultivated area, giving us a realistic picture of agricultural pressure. A country might have low overall population density but high physiological density if only a small fraction of its land is arable—this tells us far more about food security and farming intensity than crude population density ever could.

Agricultural density narrows the focus further. It takes only the agricultural population—those actually engaged in farming—and divides by net cultivable area. This ratio reveals how many farmers are working each hectare, which speaks directly to farm size, mechanization levels, and rural livelihoods. High agricultural density often signals fragmented landholdings and labor-intensive farming.

Population density is the simplest and most familiar measure: total population divided by total area. It treats all land equally, whether desert, mountain, or fertile plain, and serves as a baseline comparison across regions and countries. …

Understanding Land Use Classification in India

India's land use pattern reflects the evolving priorities of a developing nation—balancing agricultural expansion, urbanization, industrial growth, and environmental conservation. The government tracks these changes through a standardized classification system that divides the country's reporting area into nine distinct categories. Each category tells a story: forests speak to conservation efforts, net area sown reflects agricultural intensity, while categories like barren wasteland or culturable waste reveal land that is either unusable or awaiting development.

The period from 1950-51 to 2014-15 spans India's entire post-independence development journey. At independence, the country was overwhelmingly agrarian, with vast tracts of land lying unused or underutilized. Over the next six decades, population pressure, the Green Revolution, urbanization, and policy interventions reshaped how every hectare was used.

Analyzing the Changes

To identify which category decreased the most, we need to calculate the absolute change for each option:

Forests: Rose from 17% to 23.3%, an increase of 6.3 percentage points. This reflects afforestation programs and stricter forest protection laws, so this option is eliminated.

Permanent pasture and grazing land: Increased marginally from 2.3% to 3.3%, a gain of 1.0 percentage point. The slight rise suggests some recognition of the need for livestock support, though the overall share remains small. Not a decrease at all.

Barren and unculturable wasteland: Dropped sharply from 13.4% to 5.5%, a decrease of 7.9 percentage points. This is the most dramatic fall among all categories. It indicates that land once considered permanently unproductive has either been reclaimed for agriculture, converted to other uses, or reclassified as development spread into marginal areas.

Culturable wasteland: Fell from 8% to 4%, a decrease of 4.0 percentage points. While significant, this decline is smaller than that of barren wasteland. Culturable waste—land that could be farmed but isn't—naturally became a target for agricultural expansion as population and food demand grew. …

To answer this, you first need to understand what the diagram is showing. It gives the percentage of India’s total reporting area occupied by each land-use category at two points in time: 1950-51 and 2014-15. The question asks for the category with the highest difference of increase — meaning the largest positive change in percentage points from the earlier year to the later year.

Let’s look at each of the four options one by one.

Barren and unculturable wasteland actually decreased sharply, from 13.4% to 5.5%. That is a drop of about 7.9 percentage points — a decrease, not an increase. So this option is out.

Net area sown went from 41.7% to 45.5%. That is an increase of 3.8 percentage points. A solid rise, reflecting the expansion of cultivated land in the early decades after independence.

Area under non-agricultural uses jumped from 3.2% to 8.7%. That is an increase of 5.5 percentage points. This category includes land used for settlements, roads, factories, railways, and other infrastructure — all of which grew rapidly with urbanisation and industrialisation.

Current fallow rose from 3.7% to 4.9%, an increase of 1.2 percentage points. That is a modest change.

Understanding how land is used is crucial for a nation's planning and development. Land use classification categorises the total geographical area of a country based on its primary function, such as agriculture, forests, pastures, or non-agricultural uses. This classification helps in assessing resource availability, identifying trends in land utilisation, and formulating policies for sustainable development. The data provided illustrates significant shifts in these categories over several decades in India, reflecting changes in economic priorities, population growth, and environmental awareness.

One of the most important categories in land use classification, especially for an agrarian economy like India, is the 'Net Area Sown'. This refers to the total area of land on which crops are grown and harvested. It essentially represents the actual agricultural land available for cultivation in a given year. An increase in the Net Area Sown often indicates an expansion of agricultural activity, which can be driven by factors like increased food demand, technological advancements in farming, or conversion of other land types into agricultural fields. Conversely, a decrease might suggest urbanisation, industrialisation, or land degradation.

To determine the change in 'Net Area Sown' between the two periods, we simply need to find the difference between its percentage share in 2014-15 and 1950-51. …

The core idea behind this question is reading comprehension. You need to carefully read the provided text and then evaluate each given statement against the information presented in the text. The goal is to find the statement that either directly contradicts the text or cannot be inferred from it. This requires precise attention to detail and understanding the exact wording used in both the source and the options.

Here's a step-by-step analysis of each statement:

1. Analyze Statement (A): "Jhabua is tribal concentrated district."

   • The case study states: "It is characterized by high concentration of tribal population (mostly Bhils)."
   • This directly supports statement (A). Therefore, statement (A) is correct.

2. Analyze Statement (B): "Poverty has increased in the people due to land degradation."

   • The case study states: "The people suffer due to poverty which has been accentuated by the high rate of resource degradation, both forest and land."
   • The word "accentuated" means made more noticeable or intense. This implies that resource degradation (including land degradation) has worsened or increased the existing poverty. This directly supports statement (B). Therefore, statement (B) is correct.

3. Analyze Statement (C): "State government has provided money to implement watershed management programme."

   • The case study states: "The watershed management programmes funded by both the ministries of 'Rural Development' and 'Agriculture', Government of India..." …
