10 Ways to Cut Global Food Loss and Waste

This post is the third installment of WRI’s blog series, “Creating a Sustainable Food Future.” The series explores strategies to sustainably feed 9 billion people by 2050. All pieces are based on research being conducted for the 2013-2014 World Resources Report.

An amazing 24 percent of all food calories produced today go uneaten. Reducing this loss and waste is a critical step toward generating enough food for a population set to reach more than 9 billion by 2050.

Fortunately, there are low-cost methods that can begin saving food immediately in both the developing and the developed world. WRI’s new working paper, Reducing Food Loss and Waste, identifies a number of these strategies. Some methods cut loss “close to the farm,” while others reduce waste “close to the fork.”

Reducing Food Loss Close to the Farm

Improved storage methods

Simple, low-cost storage methods can drastically cut food loss, especially for small-scale farmers in the developing world, who frequently lose food to factors like pests, spoilage, and transportation damage. For example, a system developed by researchers at Purdue University in which grain is stored in three interlocking plastic bags locks out pests and keeps grain fresh for months. The Food and Agriculture Organization has built more than 45,000 small, metal storage silos—just big enough for use by a single farmer—in 16 different countries. These silos have cut food loss during the storage phase to almost zero. Even using a plastic crate instead of a plastic sack during transport can cut loss dramatically by preventing bruising and squashing.

By the Numbers: Reducing Food Loss and Waste

This post is the second installment of WRI’s blog series, “Creating a Sustainable Food Future.” The series explores strategies to sustainably feed 9 billion people by 2050. All pieces are based on research being conducted for the 2013-2014 World Resources Report. Look for the next installment tomorrow, which will highlight a number of solutions to reduce food loss and waste.

The world produces about 4 billion tons of food per year, or about 6 quadrillion calories. That’s a large amount, but what’s really shocking is that nearly one-quarter of these calories go uneaten.

This food is lost or wasted in a number of ways. It might rot in the fields, get eaten by pests in storage, or be thrown away by a grocer or consumer, just to name a few. It’s a problem that must be mitigated: The world will need about 60 percent more calories per year by 2050 in order to adequately feed the projected population of more than 9 billion people. WRI’s new working paper, Reducing Food Loss and Waste, shows that cutting current rates of food loss and waste in half would reduce the size of this food gap by about 22 percent.

The new paper, part of the ongoing 2013-2014 World Resources Report: Creating a Sustainable Food Future working paper series, looks at the scale of the food loss and waste challenge and examines how we as a global community can start tackling this issue. The paper and tomorrow’s blog post explore a number of practical, affordable strategies for governments, businesses, and households to reduce their loss and waste immediately.

But first, it’s important to understand the extent of the problem. Here are several facts and figures that reveal just how much food the world loses and wastes:

Demystifying the Role of Ecosystem Services in Impact Assessments

Ensuring that development projects benefit both people and the planet is becoming more and more of a priority.

Environmental and social impact assessments (ESIA) have been in use for decades to consider the effects of projects such as dams, highways, and oil and gas development. Over the years, ESIAs have evolved to cover both environmental and social impacts, including health and human rights.

However, the assessments often study social or environmental factors separately from one another, missing the many ways in which they interact.

In 2012, important financial institutions--the International Finance Corporation and the Equator Principles Financial Institutions--took a welcome step towards promoting a more holistic approach to impact assessment, requiring their clients to address ecosystem services as part of their due diligence.

Incorporating the concept of ecosystem services into ESIA can ensure that affected stakeholders, project developers, financial, and governmental institutions understand the full scope of a proposed project’s impacts on people and the environment. But as I recently learned at the annual conference of the International Association for Impact Assessment (IAIA) two weeks ago, there’s a lot of uncertainty about what the concept of “ecosystem services” really means and how it can be applied to conducting impact assessments. It’s a good time to clear up confusion on this critically important yet complex issue.

Making the Right Choice on Indonesia’s Forest Moratorium

This piece originally appeared in the Jakarta Post. It was co-written with Dino Patti Djalal, Ambassador of the Republic of Indonesia and WRI Board member.

Ending months of uncertainty, President Susilo Bambang Yudhoyono of Indonesia made a courageous decision last week to extend the country’s forest moratorium. The new Presidential Instruction adds another two years of protection for over 43 million hectares of primary forests and peat land — an area the size of Japan.

This was a bold decision by a leader known for his commitment to sustainability. Extending the moratorium is a victory for the Indonesian people, business, and the planet.

The moratorium will directly benefit more than 80 million Indonesians who rely on forests for their livelihood. Many of these people are extremely poor and have struggled to gain recognition for their land rights. Extending the moratorium provides an opportunity to address these crucial issues.

The Great Balancing Act: 3 Needs for a Sustainable Food Future

This post is the first installment of WRI’s blog series, “Creating a Sustainable Food Future.” The series explores strategies to sustainably feed 9 billion people by 2050. All pieces are based on research being conducted for the forthcoming World Resources Report.

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? This is one of the paramount questions the world faces over the next four decades.

Answering it requires a “great balancing act” of three needs—all of which must be met simultaneously.

Balancing 3 Needs

  1. The world needs to close the gap between the amount of food available today and the amount required in 2050. According to new WRI analysis, we’ll need about 60 percent more food calories in 2050 than in 2006 if global demand continues on its current trajectory. This gap is in part a function of increasing population and wealth. The United Nations projects that the global population will likely grow from 7 billion in 2012 to 9.3 billion by 2050. At least 3 billion more people are likely to enter the global middle class by 2030, and they will almost certainly demand more resource-intensive foods like meat and vegetable oils. At the same time, approximately 870 million of the world's poorest people remain undernourished even today.

Indonesia Extends its Forest Moratorium: What Comes Next?

Indonesia’s President Susilo Bambang Yudhoyono made a bold and courageous decision this week to extend the country’s forest moratorium. With this decision, which aims to prevent new clearing of primary forests and peat lands for another two years, the government could help protect valuable forests and drive sustainable development.

Enacted two years ago, Indonesia’s forest moratorium has already made some progress in improving forest management. However, much more can be done. The extension offers Indonesia a tremendous opportunity: a chance to reduce emissions, curb deforestation, and greatly strengthen forest governance in a country that holds some of the world’s most diverse ecosystems.

Boosting Achievements from Indonesia’s Forest Moratorium

Indonesia ranks as one of world’s biggest greenhouse gas emitters, largely due to the clearing of forest and peat lands. The forest moratorium aims to address this problem by prohibiting the award of new licenses to clear or convert primary natural forests and peat lands to agriculture or other uses. This will encompass an area of over 43 million hectares of land. Forest users with existing licenses are still allowed to operate in these regions, and there are several exceptions to the rule.

A Conversation with Nirarta “Koni” Samadhi on Indonesia’s Forests

How can Indonesia—the world’s fourth-most populous country and an emerging economic powerhouse—reduce deforestation and promote sustainable development across its vast, rapidly changing landscape?

That was a question recently posed by Nirarta “Koni” Samadhi, Deputy for the Indonesian President's Delivery Unit on Development Monitoring and Oversight and Chair of the REDD+ Task Force Working Group on Forest Monitoring. At an informal meeting of forest and development experts at WRI’s offices in Washington, D.C., Koni explored possible answers, while reporting on the Indonesian government’s efforts to map and monitor forests and improve land use policies across the country.

Koni shared some of his insights with us in a video interview. Check it out below.

Food and Fuel: 2 Grand Challenges Facing Us this Earth Day

Since the very first Earth Day more than four decades ago, the environmental movement has tackled a wide range of problems, including air pollution, contaminated water, deforestation, biodiversity loss, and more. But this Earth Day, I propose that there are two fundamental issues the movement must address over the coming decade if it is ever to defuse the tension between development and the environment. In fact, these two issues underlie many, if not most, of the world’s environmental challenges.

I’m referring here to the human quest for food and the human quest for fuel.

Unsustainable Food Production

Food production has significant―but often underestimated―impacts on the environment. Take climate, for instance: About one-quarter of the world’s annual greenhouse gas emissions are agriculture-related. In particular, nearly 13 percent of global emissions comes from livestock, fertilizer use, and farm-related energy consumption, while another 11 percent results from the clearing of forests and other ecosystems, primarily for agriculture.

Can Nutrient Trading Shrink the Gulf of Mexico's Dead Zone?

The Gulf of Mexico has the largest dead zone in the United States and the second-largest in the world. Dead zones form when excessive amounts of nitrogen and phosphorous wash into waterways and spur algal blooms, depleting the water of oxygen and killing fish, shrimp, and other marine life. The Gulf of Mexico dead zone can range between an astounding 3,000 and 8,000 square miles. At its largest, it’s about the size of Massachusetts.

Reducing this growing dead zone problem is a huge scientific, technical, economic, and political challenge. It’s a conundrum that agricultural and environmental experts from across the United States will deliberate this week at the Gulf of Mexico Hypoxia Task Force meeting in Louisville, Kentucky.

One new approach they’ll discuss is voluntary nutrient trading. According to a new study conducted by WRI staff for the EPA, this strategy could be used in the Mississippi River Basin to cost-effectively reduce nitrogen and phosphorous pollution and shrink the Gulf of Mexico dead zone.
