Listening lecture: Challenges in global food production

20th March at 2pm to 4 pm

First we watch a video and i wrote points up:

Main causes for malnutrition are
1. Insufficient grain reserves = riittämättömät vilja varastot
2. Fluctuating energy prices = energian hinnan vaihtelut
 - this effects transport in food production
3. Population trends = väestön kehitys
  -18 million new people every year more to feed
4. Rapid economic growth
5. Speculators = keinottelijat
6. Extreme weather = äärimmäiset sääolosuhteet

How to help pour people in developing countries to have enough food
1. Increase investment = lisätä investointeja
  - to grain reserves and agriculture
2. Protect natural resources = suojella luonnon varoja
3. Boost research and development = edistää tutkimusta ja kehitystä
  - better seeds and tools


Food production should increase by 70% by 2050 to meet the increasing demand for food. Milk, eggs and meat production won't be solution. It takes a lot more energy and land to produce animal products than vegetables and grain. 30-50% of food is wasted, half in developing countries and half on developed countries. In developing countries because inadequate management and storage. In developed countries mostly during processing, retailing or household. Wasted food is an environmental stress in addition it increases demand for food.
If we would stop wasting food only 4% growth in agricultural land is needed by 2050. More water is also needed and again produce animal products takes many times more water than produce grain.

Climate change will be a huge problem for agriculture in 2050.

Here is something i learned.
