Food Security: Challenges, Impacts and Management

Question

Step-by-step solution

1. Step 1

   Get the core idea (1 mark). Food security = all people having reliable access to enough food. Don't just say 'having food' — the keyword is access for everyone, all the time.

2. Step 2

   Add the quality + reliability dimension (1 mark). The FAO definition stresses food that is sufficient, safe and nutritious, available both physically and economically. Mentioning 'nutritious' or 'at all times' earns the second mark.

Question

Step-by-step solution

1. Step 1

   Short-term 1 (1 mark). Emergency food aid — the World Food Programme delivers grain and supplies during a crisis.

2. Step 2

   Short-term 2 (1 mark). Cash transfers — let people buy food locally, which also supports the local market.

3. Step 3

   Short-term 3 (1 mark). Therapeutic feeding for malnourished children (ready-to-use food such as Plumpy'Nut).

4. Step 4

   Long-term 1 (1 mark). Increase production — irrigation, HYVs (Green Revolution) and mechanisation to raise yields.

5. Step 5

   Long-term 2 (1 mark). Appropriate/intermediate technology and land reform — give farmers secure rights and affordable tools.

6. Step 6

   Long-term 3 (1 mark). Education, family planning and women's empowerment → smaller families and stronger long-term capacity; plus reducing food waste.

Question

Step-by-step solution

1. Step 1

   Deaths (1 mark). Direct deaths from starvation plus indirect deaths from disease (cholera, measles) in weakened populations.

2. Step 2

   Malnutrition and long-term ill health (1 mark). Stunting in children, cognitive damage and weakened immune systems that persist for years.

3. Step 3

   Migration/displacement (1 mark). People flee in search of food → refugees and internally displaced people, pressuring neighbouring areas.

4. Step 4

   Rising food prices (1 mark). Scarcity pushes prices up, so even those with some money can no longer afford a balanced diet — access falls further.

5. Step 5

   Economic collapse (1 mark). A weakened workforce and falling agricultural output mean recovery takes years and the country may rely on aid.

6. Step 6

   Social and political impacts (1 mark). Family separation, school dropouts and child labour, plus protests and instability as hunger fuels unrest.

Question

Step-by-step solution

1. Step 1

   Physical — drought/climate (2 marks). Low or unreliable rainfall in regions such as the Sahel reduces harvests; climate change makes droughts and floods more frequent, so output falls and crops fail.

2. Step 2

   Physical — pests, floods and poor soils (1 mark). Locust swarms (East Africa, 2020) and flooding (Bangladesh) destroy standing crops; degraded, infertile soils mean low yields even in good years.

3. Step 3

   Human — conflict (1-2 marks). War destroys farmland and infrastructure, displaces farmers and blocks aid (e.g. South Sudan, Yemen), so food cannot be grown or distributed.

4. Step 4

   Human — poverty and population growth (1-2 marks). Poverty means people cannot afford food even when it exists — most shortages are about access, not absolute supply; rapid population growth and poor transport infrastructure stretch supply and prevent food reaching markets.

Question

Step-by-step solution

1. Step 1

   Name the example (AO1). The Green Revolution in India (from the 1960s, especially the Punjab) introduced high-yield variety (HYV) seeds of wheat and rice, combined with irrigation, chemical fertilisers and pesticides.

2. Step 2

   Explain how it raised production (AO2). HYVs mature faster and respond strongly to fertiliser and water, allowing double-cropping. India's wheat output rose sharply and the country moved from importing grain to becoming broadly self-sufficient — a clear gain in food security.

3. Step 3

   Assess a disadvantage (AO3 — judgement). A key drawback is that the package favoured wealthier farmers who could afford seeds, fertiliser and irrigation, widening inequality; meanwhile heavy fertiliser and pesticide use degraded soils and lowered water tables in the Punjab. So the gain in quantity came with environmental and social costs.

4. Step 4

   Reach an overall judgement. On balance the Green Revolution greatly improved national food availability and prevented famine, but it was not equally beneficial — its sustainability is questioned because the environmental costs threaten future yields.

Question

Step-by-step solution

1. Step 1

   Define both strategies (AO1). Appropriate technology = small-scale, low-cost methods that local people can build and maintain (treadle pumps, drip irrigation, hand tools). GM crops = genetically modified varieties engineered for higher yield, drought tolerance or pest resistance.

2. Step 2

   Strengths of appropriate technology (AO2). Cheap, sustainable and locally controlled, so it suits poor rural farmers, creates no debt and is easy to repair — it spreads benefits widely and builds long-term capacity.

3. Step 3

   Strengths and risks of GM crops (AO2/AO3). GM can deliver large yield gains and resistance to drought or pests on a national scale, but seeds are expensive and often patented, creating dependence on companies, and there are environmental and consumer concerns. Big yields, but limited access for the poorest.

4. Step 4

   Reach a judgement (AO3). For the food security of the poorest in an LIC, appropriate technology is usually more effective because it is affordable and sustainable; GM may raise total output but does little for those who cannot afford the seeds. The best answer often argues for combining both depending on context.
