Introduction:

The population of the world is growing rapidly. In 1950, there were 2.5 billion people on earth, in 2010 the number had grown to 6.9 billion people. Estimations say that the world population will increase to 8-9 billion by 1950.

&nbsp;

A big part of the population in the world today do not have a sufficient amount of food to eat on a daily basis. In 2010, an estimated 882 million people were living in food-insecurity, i.e. on less than 2,100 calories/person/day.

In 2010, the percentage of people living with food-insecurity worldwide were in Asia 64%, Sub-Saharan Africa 24%, and Latin-America 5%.

In Sub-Saharan Africa, predictions say that in 2020 there will be 1 billion people, and more than half of them will be food insecure.

&nbsp;

When looking at production of food from the perspective of the growing world population, it looks problematic, especially when considering how many hundreds of millions of people that already live in food-insecurity. From this perspective it looks like will not be possible to feed the increasing billions.

&nbsp;

Looking from other angels, there might be other opportunities for how food can be produced.

Today all food we eat is produced on 0.2 ha/person worldwide. This is just a fact based on number of hectares grown, divided with 6.9 billion. But not all land is equally productive.

&nbsp;

There are nations where people are fed on less land. In China, food for almost the entire population of 1.3 billion people are produced on 0.1 ha of land per person. This is a country where food insecurity is less than in other parts of Asia. To be able to reach this productivity, land has to be well utilized and work well organized. Just from this perspective, many new ways of using and organizing land comes to mind. And there are many other questions around food production today.

&nbsp;

One essential question is about productivity. How much food is it possible to produce per ha?

This depends on what the soil consists of, and how it is treated to secure fertility. It also depends on access to water, and how the water is used. Then methods for how the crops are grown are essential for the productivity.

In Sub-Saharan Africa the yields in 2010 were less than 37% of the yields in Asia in tons/ha. This is partly due to insufficient and traditional methods in Africa and it shows that much could be done.

&nbsp;

Another question is land distribution. Many places in the world today land is not available. There are big land owners who grow on only a part of their land, other parts are not used, while at the same time other people need land.

Some countries in Africa does not have this problem, land is plentiful, and it is possible to get the right to use land from governments and local communities, such as in Mozambique.&nbsp;&nbsp;&nbsp;

&nbsp;

There are also questions about how to organize the farming if you were to do it in a country. How is it possible for people to become more productive, so they can secure a surplus-production of food for a market. Should there be big common farm production, smaller production in units, small individual farming, a combination, or something different? Cuba has some experience here, where productivity is low on big state farms, but much higher on small units and family farms.

&nbsp;

Other questions are about who the food producers are? Is agriculture promoted among youth to be both economically sustainable and give food security?&nbsp;

&nbsp;

Other questions are about food quality, how to produce healthy food that is a must for healthy people! Here biodynamic farming will play an important role.
