Question

Give 4 ways modern technology has aided food production. Explain​

Answer 1

Answer:

• Modern technology such as chemical fertilizers, pesticides, herbicides, modern agricultural machinery, artificial selection... have been used to increase food production.

• Development and use of chemical fertilizers on farm land a boots levels of nutrients in the soil, increasing crop yields.  

• Development and use of pesticides such as insecticides and fungicides a kill pests that feed on our  crops and damage them.

• Development and use of herbicides a kill weeds that compete with crops for nutrients, light, water and space a increase crop yields.

• Use of modern machinery, such as tractors and combine harvesters à enables land and crops to be managed more efficiently.

• Artificial selection to produce varieties of plants that are suited to particular climates and soil types, and breeds of animal for specific purpose such as optimum meat, milk, and wool production.

Answer 2

Answer:

Explanation:

1. GMOs

The biotechnology used to create genetically modified organisms (GMO) is critical in food technology, and also notorious. A GMO is something that has been genetically engineered to have certain traits, like herbicide resistance, pest resistance, and increased nutritional value. In 1994, the first modified tomato, the Flavr Savr, was approved by the FDA and put on the market. It quickly led to the development of other seeds, and by 1999, one hundred million acres were farmed with genetically engineered crops.

In 1997, just three years after the first genetically modified food hit the grocery shelves, Europe made GMO labels mandatory, but the US still hasn't made a federal regulation. Currently, there are crops in development that are genetically modified to grow in habitats besides their native ones, to increase yield productivity to feed more people. Examples of this include wheat, rice, and other grains. Fish, poultry, and beef are also often modified to increase the quantity of meat by quickening the rate of growth of an animal or by adding proteins or other nutrients to the meat.

2. Precision agriculture

Precision agriculture is often called satellite farming, and refers to the use of GPS tracking systems and satellite imagery to monitor crop yields, soil levels, and weather patterns to increase efficiency on the farm. Precision technology is increasingly important as the issue of feeding 9 billion people by 2050 becomes more apparent. The technology was adopted in the early 1990s, and started with crop yield monitors. Now, there are tools such as weather analysis software and soil testing kits to monitor nitrogen and phosphorous levels.

3. Drones

Farms often span large distances, and farmers need help to monitor the productivity of the areas. Drones are becoming a popular alternative to extra farm hands or satellites, and advanced technology is making the drones more productive. With drones, farmers can locate precisely where a diseased or damaged plant is, more accurately release fertilizer and pesticides, or take photos and have immediate information about a certain area of the farm.

A report released in March by the Association for Unmanned Vehicle Systems International said that drones could create 70,000 jobs after the Federal Aviation Administration approves commercial drones. But in farming, drones may replace more jobs than they create.

4. Internet of Things

Sensors are (and will continue to be) very important to food technology. The Internet of Things has already come to the farm in the forms of irrigation technologies, crop yield monitoring. A system called WaterBee collects data on soil content and other environmental factors using wireless sensors to reduce water waste.

Sensors in grain bins allow farmers to monitor the temperature and moisture levels remotely. John Deere added sensors to some of its equipment to monitor soil moisture or productivity to increase or decrease speed or prevent overlap of fertilizer or seed. Another example of IoT use on farms is Z-Trap, a device used to monitor insects and analyze data on crops remotely using GPS coordinates and wireless sensors. The base station targets specific destructive bug species, but the tool has its own communication network between all the traps on a certain field and uploads the data to a cloud.

5. Food waste tracking

We know that 40% of America's food is thrown away each year. With the help of social media and new technology, this number can be drastically reduced. Strides are being made with apps and web platforms to put the food to good use. Leloca is an app that helps restaurants minimize waste by allowing people to get deals on food (ranging from 30 to 50% off usually) within 45 minutes of a posting at nearby restaurants. Another app, 222 Million Tons, gives a suggested grocery list with a user's selected household size and meal preferences. A particularly innovative platform called LeftoverSwap matches people with leftover food to others in their area who would like to purchase cheap food and pick it up, and they offer anything from pizza to produce.

6. Hackathons

Food-centric hackathons are popping up around the globe to improve the food industry. It is a movement that is gaining traction. Food+Tech Connect held the first food hackathon, and continues to host them annually, including ones that have tackled the Farm Bill, and the meat and restaurant industries. The Future of Food Hackathon and Forum is an assembly of the leading food innovators, chefs, entrepreneurs, and designers to create solutions for the future of food. The Rural Advancement Foundation International and Farm Hack, an open source community for agriculture projects that lists local hackathons and innovations, have launched a collaborative campaign on Kickstarter for Growing Innovation, an online community to share agricultural innovations and maps of sustainable farms.
