Calorie switch the key to feeding future billions: researchers
(AFP) – 1 day ago
PARIS — Feeding Earth's expected population of nine billion by 2050 will need a switch in eating habits and farming practices if inequalities and environmental overload are to be avoided, French researchers said on Wednesday.
Teams from two institutes sketched projections for what could happen over the next four decades as the world's population swells by around 2.5 billion.
The statistical basis for their study was food production between 1961 and 2003, a period that included the "green revolution" of rice production that especially benefited Third World countries.
The researchers put forward one scenario that followed historical trends in food output and use of land in an open-market manner.
Under this projection, production would grow by 2050 thanks to intensive farming.
However, the movement towards meat production would also accelerate, inequalities between the nutritionally rich and nutritionally poor would widen, and environmental issues -- as today -- would only be addressed after they have become a problem.
A rival scenario sees low-intensity,...
