3V Answer in short5 questions
Q.1Define food security according to FAO.v
Solution

This is the FAO (1996) definition emphasizing availability, access, utilization and stability of food.

Answer:

Food security exists when all people, at all times, have physical and economic access to sufficient, safe and nutritious food to meet their dietary needs and food preferences for an active and healthy life.

Q.2What are the basic three components of food and nutrition security?v
Solution

Availability = adequate food production and supply; Access = purchasing power and distribution; Utilization = dietary quality, safe food, health and sanitation that allow nutrient absorption.

Answer:

The three basic components are: availability (sufficient food supply), access (physical and economic access to food), and utilization (proper use of food for nutrition and health).

Q.3What is the role of FCI in the Green Revolution?v
Solution

Emphasize procurement at MSP, storage, distribution and price support functions that facilitated farmer adoption of HYVs and higher production.

Answer:

FCI procured increased cereal production at MSP, maintained buffer stocks, provided storage facilities, and ensured distribution through PDS—helping stabilise prices and encourage farmers during the Green Revolution.

Q.4What are the effects of Green Revolution?v
Solution

List main positive and negative impacts briefly to provide balanced evaluation.

Answer:

Positive effects: large increases in food grain production, self-sufficiency in food, higher farmer incomes, and rural employment in some areas. Negative effects: regional disparities, increased input costs and farmer indebtedness, soil degradation, groundwater depletion, and reduced crop diversity.

Q.5Write some name of the nutrition programmes in Tamil Nadu.v
Solution

5VI Answer in detail5 questions
Q.1Elucidate why the Green Revolution was born.v
Solution

Concise explanation linking causes (food shortages, population pressure, low yields) to measures (HYVs, inputs, irrigation, policy support) and outcomes (increased production, self-sufficiency).

Answer:

The Green Revolution began in India to overcome food shortages and meet the needs of a rapidly growing population after independence. Low agricultural productivity, recurrent famines, and dependence on imports highlighted the need for higher yields. Introduction of high-yielding varieties (HYVs) of wheat and rice, expanded irrigation, increased use of fertilizers and pesticides, mechanization, and government support (credit, extension services and procurement at MSP) were adopted to boost production and achieve self-sufficiency in food grains.

Q.2Explain Minimum Support Price.v
Solution

Include purpose (income protection, production incentive), mechanism (set by government based on CACP recommendations), and role in procurement and buffer stocks.

Answer:

Minimum Support Price (MSP) is a price set by the government to purchase certain crops from farmers to protect them against sharp fall in market prices. MSP ensures farmers a minimum profit for their harvest, encourages production of particular crops, and provides procurement support (often by agencies like FCI) to maintain buffer stocks and food security.

Q.3Elaborate the Public Distribution System.v
Solution

Describe objectives, operational steps (procurement → storage → allocation → distribution), targeting mechanisms (ration cards), and the role of NFSA in entitlement and coverage.

Answer:

The Public Distribution System (PDS) is a government-run program to distribute food grains (rice, wheat, sugar, kerosene earlier) at subsidized prices through fair price shops to eligible households. Objectives: ensure food security, protect vulnerable groups, and stabilize prices. Components: procurement, storage, allocation, and distribution via ration cards and fair price shops. Variants include targeted PDS and universal PDS; the NFSA (2013) provides statutory entitlements to priority households and Antyodaya Anna Yojana beneficiaries.

Q.4What are the factors affecting the purchasing power and explain them.v
Solution

Give short explanation for each factor linking how it increases or decreases consumers' ability to buy goods and services.

Answer:

Main factors: (1) Income levels — higher income raises purchasing power; (2) Price level/inflation — rising prices reduce purchasing power; (3) Employment and wages — stable employment and real wage growth increase purchasing power; (4) Availability of goods — shortages can push up prices and reduce real access; (5) Taxes and subsidies — taxes lower disposable income while subsidies can increase real purchasing power; (6) Credit availability — access to credit can temporarily raise purchasing power.

Q.5What are the main objectives of the new Agricultural Policy?v
Solution

Concise list of policy aims: food security and stable supplies; higher production and productivity; better farmer incomes; diversification and commercialization; sustainable resource management; market/infrastructure reforms; support for research, extension and private investment.

Answer:

The main objectives are: (1) Ensure national food security by increasing foodgrain production and stabilising supplies; (2) Raise farmers' real incomes and improve rural livelihoods; (3) Increase agricultural productivity and efficiency through modern technology, irrigation, inputs and mechanisation; (4) Promote diversification to high‑value crops, horticulture, livestock and fisheries; (5) Ensure sustainable use of natural resources and conserve soil and water; (6) Improve agricultural marketing, price support and access to credit; (7) Encourage private investment and agro‑processing to add value and promote exports; (8) Reduce regional disparities and strengthen research and extension services.

7VII Activity and Project2 questions
Q.1Visit nearby "Uzhavar Sandhai" and collect the information about the functions of market.v
Solution

Provide a short report with observations on: (a) who sells and buys; (b) goods and seasonal variations; (c) price-setting and bargaining; (d) advantages to farmers and consumers; (e) any government/support services observed.

Answer:

Suggested steps: Note services offered (outpatient, maternal/child care, immunization), staff available (doctors, nurses, ASHAs), operating hours, medicine and vaccine availability, referral system, public-health programmes implemented (e.g., nutrition counselling), and patient flow. Prepare a short report summarizing findings and suggestions for improvements.
