Define Thomas Malthus' theory on food vs population.

• Population increased faster than food supply
• Population increases geometrically – 1, 2, 4, 8, 16
Food supply only increases arithmetically (1, 2, 3, 4, 5)


State a prediction that Esther Boserup has made

• A rising population
• led to shortages…
• which in turn stimulated innovation/invention…
• which led to technical breakthroughs…
which led to improvements in resource production (food)


Why may a geographer think pessimistically (Malthus)?

• Increasing population
• Greater demand for resources
• Supply rates are growing (arithmetically) slower than demographic growth (geometrically), won’t have enough resources
• Decrease is primary sector due to low wages and lack of land due to high rates of urbanisation


Why may a geographer think positively (Boserup)?

• Mechanisation – ensures more efficient harvest – releases labour for additional work extending area
• Improved infrastructure – refrigeration/fast railway routes to secure high quality crop access to market – e.g. Golden Quadrilateral.
• Use fertilisers – higher yields, increase intensity
• Use pesticides – improve reliability/ cut down crop losses
• Use agrochemicals – to allow double cropping/overcome rainfall reliability.
• Use irrigation – to allow double cropping/overcome rainfall reliability
• Green Revolution – HYV crops supported by fertilisers/irrigation.
Gene Revolution – crop breeding to improve resistance to drought/salt
