FAO Media Centre: Scarcity and degradation of land and water: growing threat to food security   Leave a comment

“Prospects for the future

FAO estimates that by 2050, rising population and incomes will require a 70 percent increase in global food production. This equates to another one billion tonnes of cereals and 200 million tonnes of livestock products produced each year.

“For nutrition to improve and for food insecurity and undernourishment to recede, future agricultural production will have to rise faster than population growth and consumption patterns adjusted,” says SOLAW.

More than four-fifths of production gains will have to occur largely on existing agricultural land through sustainable intensification that makes effective use of land and water resources while not causing them harm.

Recommendations

Improving the efficiency of water use by agriculture will be key, according to the report. Most irrigation systems across the world perform below their capacity. A combination of improved irrigation scheme management, investment in local knowledge and modern technology, knowledge development and training can increase water-use efficiency.

And innovative farming practices such as conservation agriculture, agro-forestry, integrated crop-livestock systems and integrated irrigation-aquaculture systems hold the promise of expanding production efficiently to address food security and poverty while limiting impacts on ecosystems.

FAO recently highlighted its vision for the sustainable intensification of agricultural production in its publication, Save and Grow: A New Paradigm for Agriculture, released earlier this year.

Another area where improvement is needed is increasing investment in agricultural development. Gross investment requirements between 2007 and 2050 for irrigation water management in developing countries are estimated at almost $1 trillion. Land protection and development, soil conservation and flood control will require around $160 billion worth of investment in the same period, SOLAW reports.

Finally, greater attention should be paid not only to technical options for improving efficiency and promoting sustainable intensification, but also to ensuring that national policies and institutions are modernized, collaborate together and are better equipped to cope with today’s emerging challenges of water and land resource management.”
