<p>India hasn’t outlived its carrying capacity – with adequate technology (of today!) you can feed hundreds of millions using land the size of Rhode Island. High-density farming – fish farms, high-density hydroponics, high-density live poultry warehouses … in Singapore we produce 35-45% of our own food supply (without import) even though we’re nearly 100% urban – quite good for a city-state. Give us a 100 more square kilometres we could be self-sufficient (but of course it wouldn’t be in our comparative advantage).</p>
<p>If for example world food prices shot up such that imports became less attractive, we could easily produce our own food.</p>
