Innovation of the Month: Cereal Banks Protect Against Famine and Empower Women Across the Sahel

Share

By Caitlin Aylward

Drought and high food prices in 2012 threatened the food security of over 18 million people in the Sahel Region of Africa, which includes parts of Chad, Niger, Mali, Mauritania, Burkina Faso, Senegal, Gambia, Cameroon, and northern Nigeria. The Sahel is prone to drought, and is becoming increasingly so with climate change. Consequently the people in this region are experiencing more frequent bouts of food insecurity and malnutrition.

Fortunately, organizations such as the World Food Program (WFP) and Care are joining forces to create all-women-managed cereal banks in villages throughout the Sahel that not only help protect against seasonal famine, but also empower women as agents of food security in their communities.

Cereal banks are community-led grain distribution projects that store grain after harvests, and then loan grain when food is scarce during what is known as the ‘lean season.’

In 2009, WFP and Care established exclusively women-operated cereal banks to help ensure the availability of grain supplies year round. These community cereal banks loan grain below market price, helping protect against market speculation, and enabling even the poorest women to purchase food for their families during times of scarcity. The women are expected to repay the loans, but at very low interest rates and only after they have harvested their own crops.

Camu Camu: A Little Fruit that Packs a Big Punch

Share

By Eleanor Fausold

Sometimes the best things come in small packages. Camu camu (Myrciaria dubia) is a tiny fruit native to the Amazon region of South America that is rising in popularity, as both an element in local treats and a main component in dietary supplements. Although its high level of acidity once made it unpopular for consumption, the fruit is now valued for its exceptionally high vitamin C content and is, consequently, growing in demand in health-food stores around the world.

Also known as camocamo in Peru and cacari in Brazil, among other names, the camu camu tree can grow up to 40 feet high. The species thrives in swamps along rivers and lakes such as the Rio Mazán near Iquitos, Peru, and in Amazonian Brazil and Venezuela. The base of the camu camu’s trunk is frequently underwater, and the tree’s lower branches are often submerged for long periods during the rainy season.

Despite its frequent submersion, the camu camu tree produces fragrant flowers with tiny white petals and tiny fruits that turn from yellow to a maroon or purple-black color as they ripen. In the right growing conditions, a single tree can produce as many as 1,000 fruits per year, which are harvested by boat.

Known for its extremely high vitamin C content (half-ripe fruits have been found to contain 1,950 to 2,700 milligrams per 100 grams of edible fruit, an amount greater than that found in 50 oranges), the camu camu fruit has a very acidic taste. In fact, until fairly recently, the fruit was used almost exclusively as fish bait and the tree, when dead, was used as a source of firewood.

EU Bans Class of Pesticides Thought Harmful to Bees

Share

By Laura Reynolds

On April 29, the European Union voted to largely ban the use of neonicotinoids, a type of pesticide, for two years beginning in December 2013. The ban had 15 member state supporters, including France, Germany, and Poland; eight opponents, including the United Kingdom; and four abstaining votes.

The ban restricts the use of three pesticides—imidacloprid, clothianidin, and thiamethoxam—on flowering crops, which honeybees depend on for pollen and hive health. Environmental groups, beekeepers, scientists, and the public hailed the ban as a victory for the precautionary principle, which urges caution and careful scientific study in circumstances where the effects of a chemical or action on the environment are not sufficiently clear.

Neonicotinoids are thought to be particularly harmful for insects because the chemical is applied directly to a plant’s seed instead of its leaves or flowers. This makes the pesticide present in the plant’s pollen. Neonicotinoids are also persistent chemicals, meaning that they do not degrade within weeks or months, but rather remain in the nerve systems of insects, causing systemic and lasting damage.

In the United States, a coalition of beekeeping companies and environmental groups sued the Environmental Protection Agency in March over its approval of neonicotinoids for domestic use. The groups cited a lack of scientific understanding of the pesticides’ effect on bees and other insects, and drew a possible connection between the chemicals and the ongoing collapse of honeybee hives across the country and worldwide.

This bee population crisis, known as colony collapse disorder, emerged in 2005, and scientists have not yet identified a clear cause. Numerous peer-reviewed scientific studies have both confirmed and denied a link between neonicotinoids and beehive collapse. Scientists agree that viruses, mites, drought, and loss of native habitat could also be contributing to the collapse.

Emissions from Agriculture and Livestock Continue to Grow

Share

By Laura Reynolds

In 2010, global greenhouse gas emissions from the agricultural sector totaled 4.7 billion tons of carbon dioxide (CO₂) equivalent, up 13 percent over 1990. Agriculture is the third largest contributor to global emissions by sector, following the burning of fossil fuels for power and heat, and transportation. In 2010, emissions from electricity and heat production reached 12.5 billion tons, and emissions from transport totaled 6.7 billion tons.

Despite their continuing rise, emissions from agriculture are growing at a much slower rate than the sector as a whole, demonstrating the increasing carbon efficiency of agriculture. From 1990 to 2010, the volume of agricultural production overall increased nearly 23 percent, according to data compiled by the United Nations Food and Agriculture Organization (FAO) for its program, FAOSTAT. FAO released a new GHG Emissions database for agriculture, forestry and other land use changes in Dec 2012, which can be found here.

According to FAO, methane accounts for just under half of total agricultural emissions, nitrous oxide for 36 percent, and carbon dioxide for some 14 percent. The largest source of methane emissions is enteric fermentation, or the digestion of organic materials by livestock, predominantly beef cattle. This is also the largest source of agricultural emissions overall, contributing 37 percent of the total.

Livestock contribute to global emissions in other ways as well. Manure deposited and left on pastures is a major source of nitrous oxide emissions because of its high nitrogen content. When more nitrogen is added to soil than is needed, bacteria convert the extra nitrogen into nitrous oxide and release it into the atmosphere. Emissions from manure on pasture in Asia, Africa, and South America together account for as much as 81 percent of global emissions from this source. These emissions from the three regions increased 42 percent on average between 1990 and 2010, reflecting an increase in range-based livestock populations; elsewhere, these emissions either decreased or stagnated.

Global Food Prices Continue to Rise

Share

By Sophie Wenzlau

Continuing a decade-long increase, global food prices rose 2.7 percent in 2012, reaching levels not seen since the 1960s and 1970s but still well below the price spike of 1974. Between 2000 and 2012, the World Bank global food price index increased 104.5 percent, at an average annual rate of 6.5 percent.

The price increases reverse a previous trend when real prices of food commodities declined at an average annual rate of 0.6 percent from 1960 to 1999, approaching historic lows. The sustained price decline can be attributed to farmers’ success in keeping crop yields ahead of rising worldwide food demand. Although the global population grew by 3.8 billion or 122.9 percent between 1961 and 2010, net per capita food production increased by 49 percent over this period. Advances in crop breeding and an expansion of agricultural land drove this rise in production, as farmers cultivated an additional 434 million hectares between 1961 and 2010.

Food price volatility has increased dramatically since 2006. According to the United Nations Food and Agriculture Organization (FAO), the standard deviation—or measurement of variation from the average—for food prices between 1990 and 1999 was 7.7 index points, but it increased to 22.4 index points in the 2000–12 period.

Although food price volatility has increased in the last decade, it is not a new phenomenon. According to World Bank data, the standard deviation for food prices in 1960–99 was 11.9 index points higher than in 2000–12. Some price volatility is inherent in agricultural commodities markets, as they are strongly influenced by weather shocks. But the recent upward trend in food prices and volatility can be traced to additional factors including climate change, policies promoting the use of biofuels, rising energy and fertilizer prices, poor harvests, national export restrictions, rising global food demand, and low food stocks.

Perhaps most significant has been an increase in biofuels production in the last decade. Between 2000 and 2011, global biofuels production increased more than 500 percent, due in part to higher oil prices and the adoption of biofuel mandates in the United States and European Union (EU). According to a 2012 study by the University of Bonn’s Center for Development Research, if biofuel production continues to expand according to current plans, the price of feedstock crops (particularly maize, oilseed crops, and sugar cane) will increase more than 11 percent by 2020.

Aquaponics: An Interview with Sweet Water Organics’ Matt Ray

Share

Nourishing the Planet’s Kimberlee Davies spoke recently with Matt Ray, the principal farmer for Sweet Water Organics, an aquaponics training organization in Milwaukee, about his experience in the field of aquaponics.

Sweet Water Organics uses aquaponics technology to grow food in downtown Milwaukee.

What is aquaponics? How did you become involved?

Aquaponics has been around for centuries. It was traditionally a technique in tropical climates, using floating bamboo rafts with vegetation in fresh water pools. This was simply the adaptation of agriculture to the tropics. The technique has become cutting edge over the last 20 years. We can adapt aquaponics to today’s geographies and culture.

Aquaponics is a blending of aquaculture (the raising of aquatic animals) and hydroponics (growing plants in water without soil). In aquaponics, aquatic animals serve as the nutrition base for the plants. The great thing about aquaponics is that it is a closed system; it doesn’t have to flow in one pipe and out of another.

I saw it begin to pop up in the late 1980s, starting with the Virgin Islands, Australia, and even Asia, where fish are grown symbiotically with rice paddies. Forward-thinking farmers and activists began to develop the practice in non-tropical climates, and academics began researching the field. Twenty years later, we have a lot more people doing it. Scientific data has emerged to support the spread and success of this technique. It’s possible to take the nuts and bolts and adapt them to wherever you are. It’s going to work and it can be replicated.

Argan Oil: Too Much of a Good Thing?

Share

By Carol Dreibelbis

Most people have heard of the health benefits of using olive oil instead of butter or other saturated animal fats. The monounsaturated fats in olive oil have been shown to reduce levels of harmful cholesterol, and as a result nutrition experts have touted it and other aspects of the Mediterranean Diet as heart healthy.

But olive oil isn’t the only celebrated oil from that region of the world. In Morocco, argan oil has been consumed by the Berber people for centuries. Berbers add the deep yellow, toasty-flavored oil to couscous, serve it alongside bread, or eat it on its own. Argan oil has been shown to reduce cholesterol and triglycerides in the blood, and recent research by France’s Institut Pasteur, Morocco’s Lipoproteins and Atherosclerosis Research Laboratory, and others suggests that it might contribute to the prevention of various cancers, cardiovascular diseases, and diabetes.

Beyond the health benefits of consuming argan oil, there are also important environmental benefits associated with its production. The same deep root systems that make argan trees well adapted to heat and frequent drought in southwestern Morocco also protect the land against soil erosion and desertification. Meanwhile, argan trees provide shade and protection for crops or pastureland, presenting opportunities for agroforestry.

Arguably, however, the most noteworthy impact of argan oil production is social. This rare oil has captivated a global audience, primarily because of its use in cosmetics. As a result, market prices have been on the rise (making it the most expensive edible oil in the world), and argan oil producers—largely local Moroccan women—have been reaping the benefits.

Because the process of extracting argan oil is extremely labor intensive (it can take 50 kilograms of seeds to produce just half a liter of oil), the women who produce it by hand are frequently part of production co-operatives, such as the UCFA (Union des Cooperatives des Femmes de l’Arganeraie). Founded in 1999, this innovative co-operative produces and markets argan oil and is supported by the Moroccan government as both a conservation and development strategy. Today, the UCFA unites 22 smaller women’s co-operatives. The women who make up these groups gain status, a steady income, and, in some cases, an education through their work.

Yet the argan oil boom has been a double-edged sword. Argan trees and the area in which they grow are threatened by overuse and deforestation. A study by the University of California, Davis finds that “the boom has predictably made households vigilant guardians of fruit on the tree, but it has not incited investments in longer term tree and forest health.” While the development of a UNESCO Biosphere Reserve in Morocco is a step in the right direction, it will be both economically and environmentally critical for the same non-governmental groups, development agencies, and government offices that supported argan oil production in the first place to keep sustainability in mind.

To Combat Scarcity, Increase Water-Use Efficiency in Agriculture

Share

By Sophie Wenzlau

This blog was originally published as part of an online consultation organized by The Broker  on the role of water in the post-2015 development agenda. Click here to read the original post.

The South Centre has argued that “as oil conflicts were central to 20th century history, the struggle over freshwater is set to shape a new turning point in the world order.” Water scarcity, which already affects one in three people on earth, is set to increase in magnitude and scope as the global population grows, increasing affluence drives up demand, and the climate changes. According to the UN Convention to Combat Desertification (UNCCD), “half the world’s population will be living in areas of high water stress by 2030, including 75 to 250 million people in Africa.” In the Sahel region of Africa, desertification caused by overgrazing, unsustainable farming, and the collection of wood for fuel is already responsible for systemic crop failure, soil erosion, and devastating famine. Failure to act on water scarcity will lead to more of the same.

Though water scarcity will surely play a defining role in the 21st century, the assumption that ‘water wars’ are inevitable is overly deterministic and assumes the worst of people. Historically, the need to manage trans-group or trans-boundary water basins has actually tended to facilitate cooperation between groups with competing interests. In the last fifty years, there have been only 37 incidents of acute conflict over water, while during the same period, approximately 295 international water agreements were negotiated and signed. According to Nidal Salim, director of the Global Institute for Water, Environment, and Health, the potential to peacefully overcome water scarcity does exist; it depends on political will, trust between nations, and real manifestations of cooperation.

To peacefully overcome water scarcity, leaders at all levels must prioritize efforts to cooperatively increase water-use efficiency, reduce water waste, and manage demand.

Increasing efficiency in irrigation—which is responsible for the consumption of 70 percent of the world’s total water withdrawal—would be a sensible place to start. Improved water management in agriculture could increase global water availability, catalyze development, reduce soil erosion, and lead to increased and diversified agricultural yields, augmenting our ability to feed a population projected to reach 9 billion by 2050.

New Reports Reveal the Human and Financial Costs of Large-Scale Land Acquisitions

Share

By Laura Reynolds

The Rights and Resources Initiative (RRI), a coalition of groups working for the rights of rural people to access and use their local natural resources, recently released two reports on the state of large-scale land acquisitions and investments, also known as land grabs.

The reports looked at the financial risk associated with international land investments and gave an overview of the setbacks and progress made in land tenure during 2012.

Investors, often from foreign countries, have turned to land development in recent years because of the high profits that can be made from activities such as mining, industrial food production, logging, and production of rubber or biofuels. But these investments often come with high costs as well, according to a December report from RRI. In addition to the human rights abuses and environmental destruction that can coincide with large-scale land acquisitions, investors can face an increase in their operational costs of as much as 2,800 percent.

The report, “The Financial Risks of Insecure Land Tenure: An Investment View,” profiles five foreign land investments that failed because of a lack of transparency or legality, resulting in financial hardship for the investors. In 2005, the Swedish ethanol producer SEKAB attempted to purchase 400,000 hectares in Zanzibar, Tanzania, to cultivate biofuel crops, but public outcry and the company’s failure to follow policy and environmental protocols led creditors to adandon the project and forced SEKAB to sell its assets at a loss of over $20 million.

In Grand Cape Mount, Liberia, the Malaysia-based multinational Sime Darby, the world’s largest producer of palm oil, had planned to develop 220,000 hectares for oil palm and rubber plantations after signing a 63-year concession with the national government. But land tenure disputes and large-scale rioting have repeatedly disrupted operations, putting the project’s long-term feasibility at risk.

An Interview with Tilahun Amede: Improving Water Resource Management in the Nile Basin

Share

By Carol Dreibelbis

In October 2012, Nourishing the Planet’s Carol Dreibelbis spoke with Tilahun Amede of the International Crops Research Institute for the Semi-Arid Tropics (ICRISAT). ICRISAT aims to empower people living in drylands around the world to overcome poverty, hunger, and a degraded environment through better agriculture.

For the past several years, Dr. Amede has been involved in research-for-development projects on rainwater management strategies in the Nile River Basin. He has worked for the International Water Management Institute and the International Livestock Research Institute to lead the CGIAR Challenge Programme on Water & Food’s Basin Development Challenge for the Nile.

Dr. Amede has also worked as a senior research fellow at the International Center for Tropical Agriculture and as an assistant professor at Hawassa University in Ethiopia. He has been making a valuable contribution to the fields of agronomy and water management in Africa for over 20 years, and has published more than 40 papers in peer reviewed journals.

What is a “Basin Development Challenge,” and what makes these research programs effective?

Each Basin Development Challenge (BDC) works at the river-basin level to identify one big agricultural challenge. Research then focuses on developing interventions that can improve livelihoods and ecosystem services in ways that benefit all countries in the river basin. BDCs emphasize collective action and cooperation to achieve these goals. In the drought-prone Nile basin, rainwater management has the potential to increase agricultural productivity and improve water access for all member countries.
