Good morning. In today's lecture, I'm going to talk about urban farming, and why it has become one of the fastest-growing movements in modern city planning.
00:10.42

Let me begin with a definition. Urban farming is the practice of cultivating, processing and distributing food in or around a city. It includes everything from rooftop gardens and community allotments to vertical farms that grow crops in stacked layers under artificial light.

So why has it become so popular? There are three main drivers. First, food security. As cities grow, they depend increasingly on imported food, which leaves them vulnerable to disruption in global supply chains. Producing food locally reduces that dependency.

Second, environmental concerns. Studies have shown that fruit and vegetables grown in cities can travel as little as a few kilometres from farm to table, compared with an average of fifteen hundred kilometres for conventional produce. That dramatic reduction in what we call food miles cuts carbon emissions significantly.

And third, there is a social benefit. Community gardens bring neighbours together, and have been linked to improved mental wellbeing.
01:16.46

But urban farming is not without its challenges. The most obvious is space. Land in cities is expensive, which is why rooftop and vertical farms are becoming more common. A typical vertical farm can produce ten times the yield of a traditional field farm, using a fraction of the water.

Another significant challenge is the energy cost. Vertical farms rely heavily on LED lighting, which can consume large amounts of electricity. A number of recent projects have tried to address this by pairing farms with renewable energy sources, such as solar panels on neighbouring roofs.
01:54.06
narrator_m
There is also the question of skills. Successful urban farmers need to understand not just agronomy, but also business, logistics and, increasingly, data analysis. Some universities have begun offering certificates in urban agriculture to meet this demand.
02:11.41
narrator_m
To conclude, urban farming is not a passing trend. It addresses real problems of food security and sustainability, and I believe we will see it become a standard feature of new city developments over the next two decades. That's all for today. Next week we'll be looking at water management in vertical farms.
