- The challenge of providing sufficient food for an ever-more hungry planet has never been greater.
- The number of areas reaching the limits of their production capacity is fast increasing.
- Water scarcity is growing and salinization and pollution of groundwater and degradation of water bodies and water-related ecosystems are rising.
Widespread degradation and deepening scarcity of land and water resources have placed a number of key food production systems around the globe at risk, posing a profound challenge to the task of feeding a world population expected to reach 9 billion people by 2050, according to a new FAO report published.
The State of the World’s Land and Water Resources for Food and Agriculture (SOLAW) notes that while the last 50 years witnessed a notable increase in food production, “in too many places, achievements have been associated with management practices that have degraded the land and water systems upon which food production depends.”
Today a number of those systems “face the risk of progressive breakdown of their productive capacity under a combination of excessive demographic pressure and unsustainable agriculture use and practices,” the report says. No region is immune: systems at risk can be found around the globe, from the highlands of the Andes to the steppes of Central Asia, from Australia’s Murray-Darling river basin to the central United States.
At the same time, as natural resource bottlenecks are increasingly felt, competition for land and water will become “pervasive,” the report suggests. This includes competition between urban and industrial users as well as within the agricultural sector – between livestock, staple crops, non-food crop, and biofuel production. And climate change is expected to alter the patterns of temperature, precipitation and river flows upon which the world’s food production systems depend. As a result, the challenge of providing sufficient food for an ever-more hungry planet has never been greater, SOLAW says — especially in developing countries, where quality land, soil nutrients and water are least abundant.
“The SOLAW report highlights that the collective impact of these pressures and resulting agricultural transformations have put some production systems at risk of breakdown of their environmental integrity and productive capacity. These systems at risk may simply not be able to contribute as expected in meeting human demands by 2050. The consequences in terms of hunger and poverty are unacceptable. Remedial action needs to be taken now,” said FAO Director-General Jacques Diouf.
