Technology
The purpose of this report is to find out to what extent that we should rely on technology to secure an adequate global food supply. In agriculture the term technology includes the following methods and ideas. Therefore I have to find out if these can secure an adequate global food supply in the future. However firstly it is necessary to consider what an adequate global food supply actually is. The minimum calorie intake for humans is around about 2300 - 2599. Referring to the map of Nutrition and Malnutrition around the world, to achieve an adequate global food supply all of the land that is shaded in either white, red or orange (i.e. below 2300 calories per person) should be bought up to 2300 calories or above. These are the areas where famine is lightly to be widespread. In the future supplying an adequate global food supply will depend on food supply and population growth. Currently the areas of low food availability are those areas of high population growth. An example of this is Figure 1, showing that it is the developing countries where the population is increasing. In order to answer this I need to find information relevant to:
However this was not actually the case is china was not included in these calculations. The book is outdated and the more recent figures may tell a different story. Because there are so many people malnourished today the current levels of food production will have to be increased more than proportional to growth, if the majority of humans are to be supplied with an adequate diet. The trend is also clear the other way around, where countries like Mongolia, Peru, Tanzania and Zambia have a low technology level also have a poor food supply. As long as this situation continues then it is almost impossible for technology to help, fundamental changes in economy and society must happen first. They are also the countries that have the lowest calorie per person intake, which means that they are also the countries that suffer from a poor food supply, the developing ones. Brown also argues that: 9 Yields will not increase because they are already high now, fertiliser use is high, and soil erosion and lower water availability for agriculture will cause soil fertility to decline. They argue that there is little backlog of unused technology and carrying capacity of rangeland has been exceeded. However the question is to what extent do we need technology to supply people with an adequate diet across the world. The population will continue to grow over the next 20 years (figure 1). However there are alternative views and arguments against using technology to secure an adequate global food supply. (Figure 2) The countries that are shaded red and orange in figure 3 are the countries that have the biggest population growth rate. htm Information included what the green revolution was and its results. It was the same in Asia where there was a 9% increase in food per person by 1990, but there were also 9% more hungry people.
