Feeding the growing population

By 2050 we are going to need to feed two billion more people. we are going to have to change how we grow crops. Traditionally we simply cut down forest or plow through grasslands to make our farms. To date we have farm land that is equal to the land mass of South America. Furthermore, to raise livestock we have taken even more land about the size of Africa. This has caused the loss of entire ecosystems like the great plains in the us and rain forests across the globe but mostly in south america. Even though we have taken all of this land there are still people that are hungry about 850 million pretty hard to believe right. We are going to have to focus increasing yields on less productive farms, the farms that are in this category are in Africa, Latin America and eastern Europe where they do not have the advanced farming technology. The places where the yield gaps is very low, are where high-tech farming systems have been implicated. We have ways to achieve the high yields we want while also reducing the environmental impacts of nutrient pollution and the destruction of ecosystems. New innovations in water conservation and organic fertilizers are helping as well. The farming industry is finding amazing new ways to target the application of fertilizer and pesticides by using super advanced tractors and other farming equipment, with advanced sensors to test the ground and GPS so the farmers do not even have to drive them. Furthermore now farmers are customizing their blends of fertilizer so that they are tailored for there type of soils, in other words given the soil what it does not have. This helps minimize the runoff of fertilizer in to water ways, which cause toxic algae blooms that kill ecosystems. Also, dealing with water old surface irrigation, like what we see in Virginia’s tobacco country, is being replaced by subsurface drip irrigation systems which save a ton of water. It would be much easier to feed all the people of 2050 if more of what we grew ended up feeding people and not livestock. Today about 50 percent ends up going to people and the other 50 goes to animals, make bio fuels, and other industrial products. It is really inefficient to feed our livestock¬† for every 100 calories of feed we only get 12 from chicken, 10 from pork, and 3 from beef. We also need to cut down on our waste because someone else could eat the food that we throw away and let go bad every day. So we should be able to feed 9 billion or even 10 billion in the future if we just keep innovating.

  1. This was a very interesting blog, and really opened my eyes to what we may experience in the near future. As a people we need to collectively prepare for the population increase. Overall, great blog . and I cant wait to hear more.

  2. This topic is very interesting because this will be a problem in our society in the future. The problem is that our population is continuing to grow and we might not have enough resources to help our future. I agree that we should not cut down a lot of trees. These trees are ecosystems that we are destroying for farms. I agree with what you said about cutting down on our waste. We need to cut down on waste because our waste can cause pollution in the future. The decomposition process can also cause methane gas. Methane gas is a very explosive gas that can contribute to global warming. I agree with your blog and how we need to start innovating in order to feed everyone.
