New models for sustainable agriculture - The global agri-food system is fragile, sensitive to fluctuations in the availability of resources

The global agri-food system is fragile, sensitive to fluctuations in the availability of resources (farmable land, water, nutrients, fuel, etc..) and to changes in climate, dietary habits, etc.. The paper investigates new agricultural models able to sustain the impact of climate change and demographic growth, guaranteeing productivity that is sufficient for all.

Agriculture is a complex system and increasingly fragile. For decades it was considered to be an accumulation of low level technological and scientific activity. But in recent decades, along with its relative importance in the economy of industrialized nations, the level of attention given to agriculture from public opinion has decreased.  However, for a few years, the market crisis, the decrease of the rate of growth in productivity and the emergence of serious distribution problems have brought the agri-food sector to the center of the international political and economic debate once again.

To support the great phenomena of demographic, climate, geopolitical, and economic changes that affect the planet, agriculture must search and find new medium-long term solutions.

Reaching  more sustainable agriculture may occur through the gradual adoption of agricultural models able to: produce healthy and good quality food; access global commercial circuits; be “in balance” relative to the natural environment (also with the aid of adequate production efficiency); sustain the impact of climate change; and contribute to sustainable  development.
