Urban Farming Helps Cities Tackle the Climate Crisis

Growing your own food is fun and possible, even in a tiny space, so everyone should give it a try. Cities are finding ways to encourage more people to grow food locally for a variety of reasons, and they all revolve around dealing with climate change. Cities become more resilient to climate change thanks to the benefits from an increase in urban farming. Those benefits range from local cooling effects from growing plants to the more serious food supply issues felt around the world. There’s no better time than now to try your hand at starting a small food garden.

Apart from private backyard gardens, urban gardening includes larger community gardens, allotment areas and building rooftops that allow people who don’t have backyards to also grow food. Ryerson University in downtown Toronto operates a rooftop farm on its engineering building that has a little under a quarter acre of growing space.

In that little space in the middle of the crowded city, the farm grows about 4,500 kilograms of food every year that supplies the university community and local chefs.

Growing significant amounts of food within the city is not necessarily a new concept. Karen Landman, a professor at the University of Guelph who researches urban gardening, says agriculture used to be a part of North American cities before being gradually zoned out of urban areas after the First World War.

“It’s actually a very old practice,” she said. “There is a lot of land where it could be turned into food production. And if we really had to, we could produce a lot of food. There are other cities in the world where urban agriculture is the primary source of food for many people.”

Canada’s New Budget Support Climate Friendly Farming

This week the Canadian government announced the new budget and in it are some climate-friendly moves. Farmers in Canada who practice sustainable farming practices are going to get a little more help and farmers who are using unsustainable practices will be encouraged to change what they do. Industrial farming is horrible for the environment, and arguably bad for people, so anything we can do to avoid it is helpful. The 20th century witnessed the overuse of fertilizers to make up for unsustainable industrial farming.

Reducing the use of nitrogen fertilizer sits at the heart of those recommendations — as it does in the federal budget. When applied to fields in excess, nitrogen fertilizer is broken down by microbes into nitrous oxide, explained Sean Smukler, a professor of soil science at the University of British Columbia.

That greenhouse gas is roughly 300 times more potent than CO2 and accounts for roughly half of Canada’s agricultural emissions. But soil testing and agronomic support — both of which are also funded in the budget — can help farmers substantially reduce their fertilizer use.

Money will also be available to help farmers plant cover crops and use rotational grazing. Both practices promote soil health, carbon sequestration and better long-term productivity. In the short-term, however, implementing them can be too expensive for many farmers already stretched thin by high costs and low revenues.

This Robotic 2 Acre Vertical Farm Can Replace 720 Acre Normal Farm

A new company based in California is hoping to drastically reshape our food supply in the coming years. Plenty uses vertical farming to lower its land use per crop and robots to help grow and harvest the crops. The results so far have been impressive for the young company and they see a lot of growth on the horizon. One of the benefits of vertical farming is that food is grown closer to where it’s consumed so the carbon footprint of transporting it is basically null.

The company has signed a deal to supply 430 stores with fresh produce in the States while also getting hundreds of millions of investment from various sources. The future of this vertical farming company is one to watch!

Plenty’s climate-controlled indoor farm has rows of plants growing vertically, hung from the ceiling. There are sun-mimicking LED lights shining on them, robots that move them around, and artificial intelligence (AI) managing all the variables of water, temperature, and light, and continually learning and optimizing how to grow bigger, faster, better crops. These futuristic features ensure every plant grows perfectly year-round. The conditions are so good that the farm produces 400 times more food per acre than an outdoor flat farm.

This Guy Only Ate Food He Grew for One Year

The video above tells a story about a person who grew in his garden enough food to eat for a year. Even with a small plot of land one can grow a lot of food. At our house we find that we have food to give away at the end of the summer.

Right now is a perfect time to start planning your garden to get some free food.

I hope that you are inspired to plant some food and support local farmers and growers in your area! We definitely can’t all do what I did, nor do we need to, but in the times we live in we all certainly do something to improve the world around us while increasing our own health and happiness.

Solar Panels Help Crops Grow

Solar panels on grass
Solar energy is the future and it keeps getting better. Not only are renewables cheaper than destructive gas and coal energy they also have other positive effects. Recently it’s been discovered that solar fields can be used as a really good place to grow crops. This is counterintuitive as the solar panels block the sun which plants typically love and to service the panels there needs to be a pathway where crops would thrive.

However, by planting shade-tolerant plants beneath the panels it means workers can still do their job and the plants can do theirs. The plants do well in the shade thanks to the ambient light and the increased humidity from the panels themselves. Neat!

The researchers see potential here (and in similar “agrivoltaics” experiments elsewhere) that is worth investigating and optimizing. Solar panel installations may not be compatible with the machinery used to harvest many crops, and boosting the panels higher off the ground costs extra. But there are configurations for certain crops in certain areas that can make a lot of sense. Farmers could save water, make money from a solar lease, and might even find that workers are much more comfortable and safe working under some shade—all while allowing solar arrays to expand in those areas without competing for land with agriculture.
