What is city farming and how do you do it?

The majority of the world's resources are used to feed those in the cities, so it's no wonder a movement has started where apartment dwellers can take steps to feed themselves.

The idea of 'city farms' has taken off across the globe as there is concern with rising population growth that the world will no longer be able to feed itself if we rely solely on what is produced in rural areas.

Cities only take up around 2 per cent of Earth's surface, but consume 75 per cent of its resources. The world's population looks set to reach 9 million by 2050 at which time, the current resources will not be enough to sustain everyone, as it expected that most of this growth will occur in the world's cities.

As a result, many are turning to eco-friendly products to bridge the gap, and overseas, a trend for rooftop gardens and greenhouses is emerging as city dwellers aim to take control of what is going on their tables.

The rooftop grange in Brooklyn, New York is one such example. It is the largest rooftop garden in the world and produces enough to sustain an entire suburb.

If you are looking to create your own veggie patch high in the sky, you might make some savings, plus you will be able to sustainably feed yourself.

Home grown vegetables do not use the same harmful chemicals or pesticides used in commercial production so the impact on the environment is reduced.

When you go outside to collect the fruits of your labour, you can also use items such as reusable bags to collect your items. These bags are much more environmentally friendly as they do not end up being sent straight to landfill.

The amount of waste thrown out by the increasing population is also a concern for the future as the world is rapidly running out of space to put all the rubbish that is created, so the more eco-freindly products you use, the better.
