Agricultural Population Growth Marginal as Nonagricultural Population Soars

The global agricultural population—defined as individuals dependent on agriculture, hunting, fishing, and forestry for their livelihood—accounted for over 37 percent of the world’s total population in 2011, the most recent year for which data are available. This is a decrease of 12 percent from 1980, when the world’s agricultural and nonagricultural populations were roughly the same size. Although the agricultural population shrunk as a share of total population between 1980 and 2011, it grew numerically from 2.2 billion to 2.6 billion people during this period.

Between 1980 and 2011, the nonagricultural population grew by a staggering 94 percent, from 2.2 billion to 4.4 billion people—a rate approximately five times greater than that of agricultural population growth. In both cases growth was driven by the massive increase in the world’s total population, which more than doubled between 1961 and 2011, from 3.1 billion to 7 billion people.

It should be noted that the distinction between these population groups is not the same as the rural-urban divide. Rural populations are not exclusively agricultural, nor are urban populations exclusively nonagricultural. The rural population of Africa in 2011 was 622.8 million, for instance, while the agricultural population was 520.3 million.

Although the agricultural population grew worldwide between 1980 and 2011, growth was restricted to Africa, Asia, and Oceania. During this period, this population group declined in North, Central, and South America, in the Caribbean, and in Europe.

In 2011, Africa and Asia accounted for about 95 percent of the world’s agricultural population. In contrast, the agricultural population in the Americas accounted for a little less than 4 percent. Especially in the United States, this is the result of the development and use of new and innovative technologies as well as the increased use of farm machinery, chemical fertilizers, pesticides, and irrigation systems that require less manual labor.

Putting a Dollar Value on Food Waste Estimates

By Carol Dreibelbis

The UN Food and Agriculture Organization (FAO) estimates that about one-third—or 1.3 billion metric tons—of all food produced for human consumption goes to waste each year. While it is easy to recognize the enormity of this number, it is much more difficult to make sense of it in a useful way. An October 2012 study by Jean Buzby and Jeffrey Hyman of the U.S. Department of Agriculture seeks to make food waste estimates more meaningful by attaching a dollar value.

The study measures the value of food loss in the United States at the retail (“supermarkets, megastores like Walmart, and other retail outlets”) and consumer (“food consumed at home and away from home”) levels. Findings indicate that US$165.6 billion worth of food was lost at these levels in 2008. This translates to the loss of an average of US$1.49 worth of food per person per day—totaling about US$544 per person per year—at the retail and consumer levels. At the consumer level, alone, the average American wasted almost 10 percent of the amount spent on his or her food in 2008.

Food losses on this scale are concerning, especially when viewed in the context of a growing global population. As the study explains, “The United Nations predicts that the world population will reach 9.3 billion by 2050 and this growth will require at least a 70 percent increase in food production, net of crops used for biofuels.” Considering that a reduction of food loss at the consumer and retail levels by just one percent would keep US$1.66 billion worth of food in the food supply, limiting food waste could play a major role in feeding future populations.

Food waste also places an unnecessarily heavy burden on the environment. The production, processing, storage, and transportation of food that ultimately goes to waste still consumes natural resources and other inputs, while also releasing greenhouse gases and other pollutants that stem from the food system. For example, the study points out that the production of wasted food consumes over 25 percent of all freshwater used in the U.S. and around 300 million barrels of oil.

Earlier this week, the White House Rural Council released a report highlighting the economic importance of reauthorizing the Farm Bill, the United States’ primary food and agriculture policy tool.

The bill—which impacts food prices, environmental conservation programs, international trade, agricultural research, food and nutrition programs, and the well being of rural communities—has been stalled in congress for over a year, in part due to disagreement over reductions to the food stamp program. House Republicans aim to cut $40 billion in food stamp funds over the next 10 years, while Senate Democrats aim to cut only $4 billion.

According to Agriculture Secretary Tom Vilsack, failure to pass the bill before the end of the year could double milk prices for Americans, spark retaliatory tariffs from Brazil, and leave livestock producers who have been hit by storms and drought without standard federal assistance.

The Obama Administration’s report, which urges Congress to reauthorize as soon as possible, highlights the potential benefits of a new Farm Bill. According to the Administration, the new bill could:

  1. Build on recent momentum of the U.S. agriculture economy, a key engine of economic growth;
  2. Continue federal conservation efforts, working alongside a record number of farmers and ranchers to conserve soil and water resources; (more…)

PodPonics, an indoor urban agriculture project that grows lettuce in PVC pipes inside used shipping containers, is just one of a new crop of up-and-coming urban agricultural innovators. The U.S. company, created by Dan Backhaus and Mark Liotta, currently operates a collection of six “pods,” or containers, in downtown Atlanta, Georgia, and is in the process of developing a plot of land next to Atlanta International Airport.

According to Backhaus and Liotta, growing the produce in shipping containers has many advantages. The size and scale of the containers makes it easy to standardize the light, temperature, and watering of the plants. For this reason, the PodPonics model is applicable to many different locales and situations. Backhaus and Liotta call this the “local everywhere” approach—emphasizing local production and consumption while maintaining a global focus.

Part of this global focus includes a strong dedication to environmental responsibility. Standardizing inputs allows PodPonics to conserve resources that typically are wasted in large-scale production. The closed environment of the pods prevents fertilizer runoff and allows for the recycling of water and nutrients. The pods also use energy during off-peak hours, which utilizes leftover energy in the system, helping to stabilize the city’s energy grid.

UN Says Sustainable Farming Can Help Close Global Emissions Gap

The Emissions Gap Report 2013—which involved 44 scientific groups in 17 countries and was coordinated by UNEP—measures the difference between the pledges that countries have made to cut emissions and the targets required to keep global temperature change below 2 degrees Celsius (°C).

The report finds that if the global community does not embark immediately on wide-ranging actions to narrow the greenhouse emissions gap, the chance of remaining on the least-cost path to keeping global temperature rise below 2°C this century will diminish quickly and lead to a host of challenges.

Based on the current trajectory, greenhouse gas emissions in 2020 are likely to reach 8–12 gigatons of carbon dioxide-equivalent (GtCO2e)—roughly comparable to 80 percent of current emissions from the world’s power plants. This is above the level that would provide a likely chance of remaining on the least-cost pathway; to be on track to stay within the 2°C target, emissions should reach a maximum of 44 GtCO2e by 2020, the report says.

Reductions in emissions from agriculture, an often-overlooked source of emissions, could help to close the emissions gap, the authors say. They estimate that emission-reduction potentials for the sector range from 1.1 GtCO2e to 4.3 GtCO2e.

Worldwide, agriculture contributes between 14 and 30 percent of human-caused greenhouse gas emissions because of its heavy requirements for land, water, and energy. The agriculture sector releases more emissions than every car, train, and plane in the global transportation sector.

Activities such as operating fuel-powered farm equipment, pumping water for irrigation, raising dense populations of livestock in indoor facilities, managing soils, and applying nitrogen-rich fertilizers all contribute to agriculture’s high greenhouse gas footprint.

UNEP attributes an estimated 38 percent of agricultural emissions to nitrous oxide from soils, 32 percent to methane from enteric fermentation in ruminant livestock, 12 percent to biomass burning, 11 percent to rice production, and 7 percent to manure management. Direct agricultural emissions account for 60 percent of global nitrous oxide emissions and 50 percent of global methane emissions, according to the report. (more…)

By Victoria Russo

Almost all food begins with a seed. Even when people eat meat or other animal products, those animals were most likely fed on grasses or grains that began as seeds. Seeds are the basis of plant life and growth, and without them, the world would go hungry.

The world is home to hundreds of thousands of species of plants, and it requires a diverse variety of seeds to satisfy nutritional and environmental needs. Today, Nourishing the Planet takes a closer look at five seed banks that aim to protect biodiversity and help feed the world.

1. Kew’s Millennium Seed Bank Project, Wakehurst, England

How many plant species can you think of? Of the roughly 400,000 known species, the Millennium Seed Bank aims to conserve 25 percent in the form of seeds by 2020. The seed bank is located on the grounds of Britain’s Royal Botanical Gardens, which were constructed by King Henry VII and are now considered a UNESCO World Heritage Site. Focused on conserving seeds from plants that can be used for food production, the Millennium Seed Bank currently holds seeds from over 10 percent of all plant species.

Millennium in Action

The Royal Botanical Gardens has been collecting research on seed saving since 1898 and has had a formal seed bank for 40 years. In recent years, it has concentrated on collecting seeds from environments that are most vulnerable to climate change. In addition to developing new crop varieties that are more adaptable to changing environments, the Millennium Seed Bank Project has implemented an international education program in an attempt to preserve ecosystems worldwide. A large part of its educational outreach program has taken place in rural regions of Africa, in countries including Kenya, Botswana, Burkina Faso, and Namibia. Promoting projects from nutrition to forestry to sustainable agriculture, the Millenium Seed Bank Project is working to feed the world and sustain the environment.

2. Navdanya, Uttrakhand, India

Since 1987, Vandana Shiva, who created Navdanya, has dedicated her life to protecting seed diversity. Navdanya is an agricultural research center that seeks to protect seed biodiversity and the livelihoods of small farmers. The organization believes that people should have a right to save and share seeds, and has created a seed bank that conserves only unpatented seeds.

Navdanya in Action

Since its creation, the Navdanya seed bank has conserved around 5,000 crop varieties, focusing largely on the preservation of grain species. The 54 community seed banks that Navdanya has piloted have preserved nearly 3,000 species of rice alone. In addition to protecting seed biodiversity, Navdanya aims to spread agricultural information through educational campaigns.

3. Svalbard Global Seed Vault, Svalbard, Norway

Preserving seeds for long periods of time requires extremely cold temperatures and low humidity. That’s why Svalbard Global Seed Vault, located deep in the permafrost-covered mountains of Svalbard, was deemed the ide
