Urban agriculture

People grow food in big cities.

They use small plots of land. Some grow food on rooftops.

This helps people get fresh food. It can also help the Earth. Growing food nearby means less travel.

Long ago, people did this too. They grew plants inside city walls.

Some people grow food to make money. Others grow food to help their neighbors. It is a way to work together.

School gardens are also very helpful. They help kids learn about plants.

Gardening is a great way to grow.

Urban agriculture is growing food in cities.

People can grow plants in many ways. They might use small garden plots. Some people even use rooftops.

They can also raise animals or keep bees. This helps people get fresh food. It also helps the Earth. Growing food nearby means less travel for trucks. This can help the climate.

People have done this for a very long time. Long ago, farmers in Mesopotamia grew food inside city walls. In Mexico, the Aztecs used chinampas. These were special gardens built on lakes.

During hard times, like wars, people grew "victory gardens." These gardens helped feed families when food was scarce. In the 1890s, Detroit grew potato patches to help people in need.

Today, many people garden to help their neighbors. Some groups use vacant lots to make cities look better. School gardens are also popular. They help students learn how plants grow.

Gardening is a way to build a strong community.

{ "text": "Urban agriculture means growing, processing, and sharing food right in the middle of a city.

It is not just about planting vegetables in a backyard. This practice includes raising animals, keeping bees, and even farming in water.

Some people do this to help the planet by reducing food miles. This means food does not have to travel far on big trucks.

When food is grown nearby, it can help lower greenhouse gas emissions. Many people also use it to find fresh food and earn money.\n\nThere are many different ways to make an urban farm work.

People might use small community gardens or even rooftops for their plants.

Some groups use a method called permaculture to help nature thrive. In some places, like Bristol, the Severn Project uses gardens to provide 34 tons of food every year.

These projects often help people who are looking for work. Even school gardens are common ways to teach kids about growing food.

These gardens help students learn about plants and healthy eating.\n\nPeople have been farming in cities for thousands of years.

Ancient Mesopotamian cultures grew food in small plots inside city walls around 3500 BC.

In Mexico, the Aztecs used chinampas, which were special gardens built on lakes. The Incas at Machu Picchu used stepped architecture to save water for their crops.

In China, the city of Xi'an has had people farming in the city for a very long time. These ancient methods helped large groups of people live together in big cities.\n\nUrban farming has often helped people during very difficult times.

In the 1890s, Detroit used \"Pingree's Potato Patches\" to help people during an economic depression.

During World War One, many people grew \"victory gardens\" to help feed their country. By 1919, there were 5 million of these plots in the United States.

During the Great Depression, these gardens produced over 2.8 million dollars worth of food. Even during World War Two, victory gardens were used to help the nation stay strong.\n\nToday, urban agriculture connects people in many new ways.

Some groups use gardens to help immigrants keep their cultural traditions alive.

Other groups use vacant lots to make cities look more beautiful.

Some people focus on \"sustainable food networks\" to help the environment.

Others join "local food movements" to change how we buy and eat. These different groups show how much people care about their food and their neighbors.", "media": [ "File:Urban agriculture in Amsterdam.jpg", "File:Mudchute farm cow head.jpg", "File:Rooftop farm at the Essex (65787p).jpg", "File:Tomato plant at Roof garden in Mymensingh, Bangladesh.jpg", "File:Foodrooffarm.jpg", "File:Kaicycle Urban Farm Wellington 05.jpg", "File:City experiment in gardening, New York City LCCN93501876.jpg", "File:Maler der Grabkammer des Sennudem 001.jpg", "File:Tenochtitlan chinampas.jpg", "File:HuertoRomita03.JPG", "File:Victorygarden usa.jpg", "File:Los Angeles Farmers Market 1953-4.jpeg", "File:New crops-Chicago urban farm.jpg", "File:The-rainbow-themed-flowers-are-arranged-in-a-figure-8-formation-This-part-of-the-garden.jpg", "File:Tomato plants growing July 2013 in garbage cans.JPG", "File:Green guerillas.jpg", "File:Urban farm, Baltimore (9373).jpg" ] }

Urban agriculture is the practice of cultivating, processing, and distributing food within urban areas.

This field covers many activities beyond simple vegetable gardening. It includes animal husbandry, which is the raising of livestock. It also involves aquaculture, the farming of aquatic organisms like fish. Beekeeping and horticulture, the art of garden cultivation, are also key components. This practice differs from peri-urban agriculture, which occurs in rural areas near the edges of suburbs. Urban farming helps reduce food miles. This means food travels shorter distances to reach consumers. Shorter travel distances can lower greenhouse gas emissions. This helps in climate change mitigation, which is the effort to reduce global warming.

Practicing urban agriculture requires careful management of the environment. One major challenge is legacy soil contamination. This refers to old pollution left in the ground. Many urban soils contain lead or other heavy metals. These substances can pose risks to human health and food safety. Therefore, farmers must address these contaminants to grow safe food.

Some people use rooftop gardens to find more space.

Others use community gardens to provide food for those in need. These spaces allow people to learn about horticulture through trial and error. In Bristol, the Severn Project provides 34 tons of produce every year. This project also helps people from disadvantaged backgrounds find work.

There are distinct types of urban agricultural sites. The two main categories are gardens and farms. The USDA defines a farm as any place producing $1,000 or more in agricultural products annually. In Europe, people often use the term "city farm" for these spaces.

Gardens are often used for recreation, education, and community building. School gardens are a specific type used to teach students about agriculture. These programs began in the 1890s in Massachusetts. They aim to improve the health and education of young people.

Other sites focus on permaculture, which is a way of farming that mimics natural ecosystems.

History shows that urban farming has existed for thousands of years.

In Mesopotamia, farmers used small plots inside city walls around 3500 BC. In Persia, aqueducts carried mountain water to support desert towns. The famous Hanging Gardens of Babylon are a legendary example from this region. In China, the city of Xi'an has practiced urban agriculture for at least 5,000 years. The Incas at Machu Picchu used stepped architecture to conserve water.

The Aztecs used chinampas, which are lake-based garden plots, to grow food in Mexico. In the Americas, the Pueblo cultures used mesa agricultural plots in the Four Corners region.

Urban agriculture has often served as a tool during economic crises. In the 1890s, Detroit faced a severe economic depression. Mayor Hazen S. Pingree created "Pingree's Potato Patches" to help citizens. These were makeshift gardens used to produce food and income. During World War One, food production became a matter of national security. The United States launched the National War Garden Committee. They used patriotic messages like "Sow the Seeds of Victory." By 1919, there were 5 million victory garden plots in the US. These plots harvested over 500 million pounds of produce.

During the Great Depression, subsistence gardens provided jobs and food. These gardens produced over $2.8 million worth of food for those in need. This helped boost economic growth and spirits during harsh times. During World War Two, the National Victory Garden Program was established. These gardens were called the "first line of defense" for the country. About 5.5 million Americans participated in this movement. They grew over nine million pounds of produce each year. This accounted for 44% of all US-grown produce during the war.

Modern urban agriculture is driven by many different social motivations. Some practitioners belong to the "locavore" movement. Locavores seek to eat food grown locally to support their community. Others focus on social justice or the preservation of immigrant cultures. For example, Hmong American communities use agriculture to maintain cultural ties. Some groups focus on sustainable food networks to help the environment. Others join local food movements to respond to globalization.

These diverse groups continue to reshape how cities function and feed themselves.
