A sustainable food future will require reductions in greenhouse gas emissions from agriculture even as the world produces substantially more food. The production of rice, the staple crop for the majority of the world’s population, emits large quantities of methane, a potent greenhouse gas.
creating a sustainable food future
The world is on a path to need almost 70 percent more crops in 2050 than those it produced in 2006. To close that crop gap without large price increases or clearing more valuable forests and savannas, yields are going to have to grow 33 percent more in the next 44 years than they did in the last 44.
Using advances in molecular biology to breed better crops can sustainably secure more of the global food supply.
The world needs to close a 69 percent gap between the crops produced in 2006 and the crops the world is on a course to need by 2050.
Quantifiable indicators of the environmental sustainability of agriculture—by which we mean minimizing the environmental impacts of agriculture—are an important tool for helping move the world toward a sustainable food future.
How does the world feed more than 9 billion people in the year 2050 in a manner that not only advances economic development but also reduces agriculture’s impact on the environment? How will we know if we’re on the right path?
WRI recently reviewed a number of existing indicators on the environmental sustainability of agriculture and identified gaps. Our analysis uncovers a need for improvements in indicators as well as the data underlying them—in particular, what we call the “3Ps, 5 themes, and 7 criteria.”
Report Presents New Findings and Recommendations for Sustainable Aquaculture
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?
Fish—including finfish and shellfish—are an important item in the human food basket, contributing 17 percent of the global animal-based protein supply in 2010. They are an especially valuable food source in developing countries, where more than 75 percent of the world’s fish consumption occurs.
Improving Productivity and Environmental Performance of Aquaculture, Installment 5 of Creating a Sustainable Food Future, explores the potential role of fish farming, i.e., aquaculture in meeting global fish demand in 2050. This chart reveals aquaculture’s growth from 1950-2050, globally, and projects that aquaculture production will need to more than double by midcentury.
The world is projected to hold a whopping 9.6 billion people by 2050. Figuring out how to feed all these people—while also advancing rural development, reducing greenhouse gas emissions, and protecting valuable ecosystems—is one of the greatest challenges of our era.
So what’s causing the global food challenge, and how can the world solve it? We begin to answer these questions through a series of graphics below.

Actions Needed to Improve Food Production and Consumption to Close the Projected 70 Percent Gap by 2050
The world’s agricultural system faces a great balancing act. To meet different human needs, by 2050 it must simultaneously produce far more food for a population expected to reach about 9.6 billion, provide economic opportunities for the hundreds of millions of rural poor who
COPENHAGEN//WASHINGTON — The World Resources Institute (WRI) today announced the first step in designing a global standard for measuring food loss and waste.
Innovative farmers are beginning to demonstrate how agroforestry and other relatively simple practices can significantly boost food production in Africa’s drylands. In fact, according to a new WRI working paper, improving land and water management on just 25 percent of sub-Saharan Africa’s 300 million hectares of prime cropland would result in an additional 22 million tons of food. This strategy could go a long way towards sustainably feeding Africa—and the world.
The world’s food production systems face enormous challenges. Millions of farmers in developing countries are struggling to feed their families as they contend with land degradation, land use pressures, and climate change.
The world’s population will rise from just over 7 billion in 2012 to nearly 9.6 billion by 2050. Most of the world’s regions have already achieved or are close to achieving replacement level fertility.
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.
How can the world feed more than 9 billion people by 2050 in a manner that advances economic development and reduces pressure on the environment? Answering it requires a “great balancing act” of three needs—each of which must be met simultaneously.
