Subsistance of Agriculture Productivity
The twentieth century is described as the century of major technological revolutions. Technology has allowed, among other things, a victory on major diseases, increased mobility of men and goods, the conquest of the sky and space, long-distance communications, the computer revolution.
This article focuses on these advances without, which it would have been much slower and partial: the control of access to food. It is an essential which, paradoxically, has become a large part of humanity access so obvious – at least in Western nations well equipped – the concern is passed to the second plan, even forgotten . This revolution is based on a tremendous increase in agricultural productivity.
Easy access to an abundant supply of cheap and quality is certainly a powerful public health policy, the major twentieth century, although all regions of the world have not benefited either synchronously or shared this improvement.
This progress is particularly pressing the tremendous increase in agricultural productivity, accelerating the phenomenon after the end of the Second World War, freeing arms for other industries and to a continued decline in the price of agricultural commodities.
But this development has been shared so far? Shared between the company and farmers? Shared between farmers in different countries? Was it sustainable, given the means used to obtain it?
The increase in productivity per unit area in agriculture is based on several technical factors: the breeding and advances in genetics, fertilizers, pesticides for plant protection, irrigation, drainage and mechanization.
