Answer:
The global demand for food, water and energy is expected to increase by about 40 to 50 percent by 2030.
This is driven in part by an expanding population, rapid urbanization, greater prosperity and changing diets.
Meeting the increasing demand requires smarter, greener and more efficient food systems – especially as the climate changes and natural resources become scarcer.
“Doubling food production by 2030 will not come from putting more fertile land into production but mainly from sustainably intensifying production – that is, getting more from agricultural lands already in use – and from using marginal lands, such as drylands,” said Alessandro Flammini, an FAO natural resources officer.
The FAO Investment Days, which this year focused on innovations in agriculture, showcased technologies and practices for restoring degraded lands and growing food in the desert.
