Making transport sustainable for all city residents is a prominent part of the New Urban Agenda, the outcome document of the Habitat III conference. Making that vision a reality presents challenges to city leaders who struggle to address the immediate need to move people from homes to jobs with limited resources.

As the global wild fish catch peaked in the 1990s, aquaculture—or fish farming—has grown rapidly to meet world fish demand, more than doubling production between 2000 and 2012. New research shows that aquaculture production will need to more than double again between now and 2050 to meet the demands of a growing population.
The question is: Can aquaculture grow sustainably?
The United Nations’ new population growth projections show that the world is set to reach nearly 9.6 billion by 2050. This growth holds serious implications for global food security. Absent other effective measures to control dietary shifts and reduce food loss and waste, the world will need to produce about 70 percent more food annually by 2050 to meet global demands. That is a big task, and even harder to do without converting millions more hectares of forests into farmland, contributing to climate change.
Today is World Food Day, a chance for people all over the world to focus on approaches to end global hunger. Celebrated each year to commemorate the founding of the UN Food and Agriculture Organization (FAO), this day provides us with an opportunity to assess where the world is today in regard to food security – and what we’ll all have to do in the future to achieve it.
How Do You Feed 9 Billion People by 2050?
For much of the planet, food security isn’t a concern on just one day of the year—it’s a daily struggle. According to the FAO, 870 million of the world’s poor are already undernourished, and yet global human population is projected to increase from 7 billion to more than 9 billion by 2050. To sufficiently feed these people, worldwide food availability will need to increase by at least 52 percent from 2007 levels.
Yet agriculture is already having huge impacts on the world’s environment and resources. For instance, agriculture is the direct driver of about 80 percent of tropical deforestation. Agriculture is responsible for up to 85 percent of the world’s consumption of freshwater, and nutrient runoff is a major cause of water quality degradation globally. And according to WRI’s Climate Analysis Indicators Tool (CAIT), food production accounts for up to 27 percent of global greenhouse gas emissions per year due to deforestation, livestock, energy consumption on farms, and fertilizer use.
