Population Dividend
Population dividend, or demographic dividend as it is called when speaking of economic growth is a term that denotes the potential growth which a country can exploit when a larger part of its population is in the working-age group (15-64 years) rather than dependents (children and the old age). India is among such countries, with 65% of its population being below 35 years old.
Factors Influencing India’s Population Dividend in Coming Years .
1. Education and Skill Development
– The workforce must be equipped with the skills the market needs, which can only come from quality education and vocational training.
2. Job Creation
– India has to create a lot of job opportunities, especially in manufacturing, services, and technology sectors, to accommodate the young population. If not enough job growth, the demographic dividend could become a demographic liability.
3. Healthcare A healthy workforce is pivotal to sustained productivity. The lack of healthcare infrastructure and the newly emerging lifestyle diseases could be the main reasons why such productivity will not be achieved by the working-age population.
4. Gender Inclusion
– The inclusion of women in the workforce is a strong factor in maximizing the demographic dividend. The percent of women who are a part of the workforce in India, at the moment, is really small, which is one of the main economy-constrainers.
5. Regional Disparities – The northern Indian states like Bihar and Uttar Pradesh are seeing a youth surge after enjoying decades of fertility decline and increasing female literacy. On the other hand, the southern states with Kerala and Tamil Nadu are struggling due to the aging population. Such a situation would mean that only a part of this demographic would be representative of a region and, at the same time, may create disparities in the development of different areas of the country.
6. Automation and Technology
The rise of technology innovation, in particular, the expansion of the industry of automation, is expected to result in the reduction of low-skilled jobs. The only way India could ensure that its workforce is ready for this is by investing in the upskilling of its workforce for the upcoming industries.
Population dividends in India are noteworthy concepts of realization. They present a wonderful chance for economic growth. A timely and proper response to this valuable opportunity would require strategic actions in the fields of education, healthcare, job creation, and gender inclusion. If this would not be realized, the potential benefit would be lost and socio-economic challenges would emerge.

1. Effective Procurement Systems
Northern and Western India have robust milk cooperative networks, which ensure regular procurement and accurate measurements, leading to better rates per liter of milk. A prime example is Amul in Gujarat, which plays a crucial role in the region’s dairy success.
2. Livestock Strengths
The region is home to a large population of milch animals, including high-yielding breeds of cattle and buffaloes. For instance, UP has the highest population of buffaloes in India, with breeds like Murrah and Jaffarabadi being prevalent in these states, further boosting milk production.
3. Localized Policy Support
At the district level, milk unions in Northern and Western India have implemented policies that promote dairy development. An example is Banaskantha Milk Union in Gujarat, which has designed 20 different schemes to support its producer members.
4. Cattle Feed Production
States such as Punjab, Haryana, and Himachal Pradesh ensure a steady supply of both green and dry fodder, contributing to enhanced cattle productivity.
5. Veterinary Infrastructure
Higher-income states like Punjab and Haryana have better veterinary infrastructure, which ensures proper care and high productivity of livestock.
Impact of Dairy on Economic Development
1. Poverty Alleviation
The dairy industry provides diverse income opportunities, such as selling milk products, manure, and biogas. In UP, nearly a quarter of households rely on animal husbandry to escape poverty.
2. Employment Generation
The dairy sector is a significant source of employment, particularly for landless farmers. For example, dairy farming generates an average of 193 person-days per year in rural Punjab.
3. Women Empowerment
Dairy farming plays a pivotal role in empowering women, as livestock ownership is one of the few avenues for women’s economic independence. In Gujarat, 36% of milk producers are women.
4. Improved Quality of Life
Dairy products contribute to better nutrition, which leads to improved health and productivity. Punjab and Haryana have the highest per capita milk availability, directly impacting rural populations’ well-being.
Thus, the dairy industry in Northern and Western India plays a critical role in driving economic development, enhancing rural livelihoods, empowering women, and improving food security.

Model Answer
Barrier Effect
The Western Ghats serve as a significant barrier to the monsoonal winds that arrive from the southwest. As these winds encounter the mountains, they are forced to rise, resulting in orographic rainfall. This effect leads to substantial precipitation in the region, with 65% to 80% of annual rainfall occurring between June and September (Source: meteorological studies).
Gaps in the Western Ghats
Despite their overall barrier function, the Western Ghats feature gaps that allow rain-bearing winds to pass through with less precipitation. A notable example is the Palghat Gap, which is approximately 30 kilometers wide and located between the Nilgiri and Anamalai Hills in Kerala. This gap enables winds to cross over to the leeward side, leading to reduced rainfall in the immediate coastal areas (Source: geographic studies).
Variations in Mountain Topography
The topography of the Western Ghats varies significantly. In Karnataka, the broader mountains compel rain-bearing winds to travel greater distances, allowing more time for moisture to coalesce and resulting in higher rainfall (Source: hydrological analyses).
Increased Convection
The gentle slopes of the Karnataka Western Ghats absorb more sunlight, promoting greater convection compared to the steeper slopes found in Maharashtra and Kerala. This enhanced convection contributes to increased rainfall in these areas (Source: climate studies).
Distance from Peak
Interestingly, areas of heavy rainfall are often found up to 50 kilometers away from the mountain peaks. This phenomenon occurs because the distance allows for better moisture accumulation in cloud formations (Source: meteorological research).
Cyclones
Additionally, the Arabian Sea has seen more frequent cyclones in recent years during the onset of the South-West monsoon. The Western Ghats act as a barrier for these cyclonic storms, reducing their intensity and protecting the coastal regions of India (Source: climatological studies).
In summary, the Western Ghats significantly regulate South-West monsoonal rainfall in India’s coastal regions through orographic lifting, variations in topography, and their role in influencing cyclonic activity.

When a farmer plants only one crop species in each field this style of farming creates serious problems for our environment.
Soil Degradation:
-Nutrient Depletion: When farmers keep planting the same crop year after year they drain essential nutrients from their soil which harms its planting ability.
-Erosion: When farmers cultivate monoculture they break up soil on fields which then leads to more erosion on hillsides especially.
-Organic Matter Reduced: When farmers grow only one type of plant in their field their crops produce fewer diverse roots which then leads to reduced organic matter entering the soil and poorer soil conditions.
Biodiversity Loss:
Habitat Destruction: Large-scale single-crop operations destroy natural vegetation which eliminates shelter for nearly all plants insects and animals.
-Pest and Disease Outbreaks: When farmers plant only one type of crop over many acres disease and insect threats become bigger problems that push up pesticide use.
Water Pollution:
-Chemical Runoff: When fertilizer and pesticide use gets out of hand they taint their way through groundwater and surface water systems.
-Increased Water Use: Corn and cotton fields consume large amounts of water which stresses our water supplies.
Climate Change:
See less-Greenhouse Gas Emissions: Monoculture farming depends heavily on fossil fuel tools and synthetic farming compounds which both create CO2 emissions.
-Reduced Carbon Sequestration: Our monoculture farmlands store less carbon because they host lower amounts of plant diversity than diverse natural habitats.

Model Answer
The improper disposal of Construction and Demolition (C&D) waste, particularly in open drains and water channels, leads to blockages during heavy rains, exacerbating urban flooding. For example, the 2015 Chennai floods were worsened by the obstruction of stormwater drains caused by discarded C&D debris (Building Material Promotion Council).
Hydrological Disruption and Ecological Damage
When C&D waste is discarded in sensitive areas like wetlands, riverbeds, or water channels, it disrupts the natural hydrological balance and damages aquatic ecosystems. The Yamuna River in Delhi has experienced significant ecological degradation due to C&D waste dumping in its riverbed (Source: BMPC).
Soil and Water Pollution
C&D waste often releases leachate and fine chemical particles, contaminating soil and groundwater. These pollutants degrade soil quality and contribute to land and water pollution, posing long-term environmental risks.
Fugitive Dust Pollution
C&D activities contribute significantly to fugitive dust pollution, which contains harmful substances such as silica, asbestos, and lead. In Delhi, the construction sector is a major contributor to PM2.5 pollution, which worsens air quality and can lead to smog formation .
Landfill Overload

Model Answer
Challenges Faced by the Sugar Industry in India
Despite India having the largest area under sugarcane cultivation, the yield per hectare is very low (88 metric tons per hectare), which hampers overall sugar production and the supply to mill.
Sugar prices fluctuate due to seasonal demand, varying sugarcane production caused by climate change, and other factors. These fluctuations not only impact the industry but also lead to uncertainty for consumers.
Small mills, outdated production technologies, and heavy excise duties contribute to the high cost of sugar production, leading to reduced profitability.
The entire sugar value chain, including sugarcane procurement prices, distribution, export quotas, and ethanol pricing, is heavily regulated by the government. This regulation prevents the industry from benefiting from global price rise.
Can Ethanol Demand Contribute to Sustainability?
Ethanol blending offers a structural shift by allowing sugar mills to flexibly move between sugar and ethanol production, smoothing out the cyclicality caused by fluctuating sugar production cycles.
Focusing on ethanol production allows sugar factories to operate throughout the year, as the government incentivizes the use of various feedstocks. This can help sustain the livelihoods of sugarcane farmers and mill workers.
By diverting surplus sugarcane into ethanol production, India can manage excess sugar production, helping stabilize sugar prices.
Ethanol production leads to faster payment realization for farmers, as ethanol sales provide quicker returns compared to sugar sales.
The demand for new feedstocks like rice, maize, and jowar can benefit states such as Bihar, a major maize producer.
In conclusion, while ethanol demand can provide significant benefits to the sugar industry, it is crucial to balance the needs of the sugar industry with food security concerns.
