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.

From Waste to Food to Fuel: Rice Production and Green Charcoal in Senegal

By Andrew Alesbury

Inadequate management of human waste is a dire problem in much of the developing world. Swelling urban populations can make matters worse by exposing increasingly dense populations to illnesses carried by human waste. Some, however, are making good use of the surplus sewage. Rather than allow the urine and fecal matter to lie fallow, some have taken to utilizing it for agricultural purposes in lieu of synthetic or inorganic fertilizers. This practice not only makes fertilizer more readily available to farmers who might not have easy access to it in conventional forms, it is also significantly less expensive than using inorganic and synthetic fertilizers, which are often imported. Furthermore, the use of human fertilizer can sometimes be a crop-saving tactic when water is in short supply.

It is with these benefits in mind that groups like AgriDjalo, a small limited liability company focused on rice cultivation, are looking to start projects in Senegal that use urban biomass (primarily human waste) to fertilize rice fields. With over 40 percent of Senegal’s almost 13 million inhabitants living in urban areas, there is an abundant supply of human fertilizer.

AgriDjalo’s project could have the added benefit of decreasing reliance on rice imports. In 2012 alone, Senegal imported 820,000 metric tons of rice, accounting for over 6 percent of its total imports and presenting a considerable strain on the nation’s trade balance. As the second largest rice importer in Sub-Saharan Africa and one of the top ten worldwide, Senegal has much to gain, both in terms of income generation and decreased import dependency, from an increase in domestic rice production.

Innovation of the Week: Community Animal Health Workers

Share

By Brandon Pierce

Animal health services for livestock owners in several parts of sub-Saharan Africa are limited because of poor infrastructure and high delivery costs. To address this deficiency, the UN Food and Agriculture Organization (FAO) has supported the training and use of Community Animal Health Workers (CAHWs) in these regions. CAHWs are community members who have been trained in basic animal health care. The FAO is taking steps to standardize how CAHWs are trained and to connect them with reliable sources of needed drugs and materials.

In Ethiopia, government supply systems often run out of the drugs livestock owners need for animal healthcare, which makes it difficult for CAHWs to effectively care for livestock. To meet the high demand for drugs, the FAO has worked to establish private pharmacies in Ethiopia and establish partnerships with CAHWs. So far, these efforts have been successful: over 30 pharmacies have been established, and these pharmacies have been linked to 600 CAHWs. To further improve CAHW programs, the Ethiopian government has developed minimum requirements and standards—such as the availability of training manuals for workers.

Kenya has also benefitted from the FAO’s CAHW program. During the 1990s, many Kenyan livestock owners were unable to afford the cost of treatment for their animals. Today, various CAHW programs—including the Community Livelihood Empowerment Project—have improved the availability of animal healthcare, reduced the cost of treatment, and ultimately improved livestock owners’ livelihoods.

Zeer Pots: A Simple Way to Reduce Post-Harvest Food Waste

Post-harvest food losses occur mainly in the developing world, and can be attributed to poor storage facilities, inadequate distribution networks, and low investment in food production. Improved storage conditions could drastically reduce this food waste, yet technologies must be affordable and realistic to be sustainable in these regions.

According to the United Nations Food and Agriculture Organization, in Guinea, where up to 80 percent of citizens depend on agriculture for their incomes, about 20 percent of crops are lost in the post-harvest stage. These losses reduce the profit for farmers and increase prices for consumers. In developing countries where the majority of disposable income is spent on food, post-harvest losses can be financially damaging.

In Zambia, storage containers are commonly built out of twigs, poles, or plastic bags. Unsealed, unrefrigerated containers such as these can allow contamination from pests, rodents, and fungi. In hot climates, perishable foods such as berries and tomatoes typically do not last longer than two days without refrigeration. Without proper storage facilities, rural farmers have to watch their ripened crops succumb to rot, infestation, and mold.

Practical Action, a nongovernmental organization that works with farmers in Southern Africa, Latin America, and South Asia, encourages the use of earthenware refrigerators called zeer pots to help prevent post-harvest food waste. The pot-in-pot refrigerator design keeps fruits and vegetables cool by harnessing the principle of evaporative cooling. These pots can extend the shelf life of harvested crops by up to 20 days by reducing storage temperature.

The design consists of a large outer pot and a smaller inner pot, both made from locally available clay. Wet sand is added between the two pots and is kept moist. Evaporation of the liquid in the sand draws heat out of the inner pot, in which food can be stored.

By Kimberlee Davies

With one of the lowest GDPs and highest malnutrition rates in the world, Ethiopia desperately needs food security investment and innovation. The U.S. Agency for International Development (USAID) recently awarded a contract to CNFA, a Washington, D.C.-based nonprofit, to implement the Agricultural Growth Program–Livestock Growth Project (AGP-LGP) in Ethiopia. The program, sponsored by USAID’s Feed the Future initiative, will encourage growth in the farming sector by increasing the competitiveness and value of Ethiopia’s livestock. CNFA expects the program to create roughly 2,600 new jobs and to improve the nutrition of 200,000 households.

In 2009, Feed the Future—a U.S. executive initiative resulting from the 2009 World Summit on Food Security—selected 20 countries, including Ethiopia, to work with on strengthening food security. Ethiopia was chosen for its high level of need and the Ethiopian government’s openness to partnership. Currently, Ethiopia’s annual per capita income is only US$170, and 30 percent of children under five are underweight. Livestock contribute to the livelihood of 60 to 70 percent of the population.

CNFA already has enacted a similar livestock program in Kenya. The Kenya Drylands Livestock Development Program (KDLDP) was one of the first programs implemented in Africa under Feed the Future, and has successfully increased livestock value and yields through improved production, marketing, and market access. Fattening animals and processing livestock products near production areas results in higher prices, thereby increasing local incomes and promoting employment among underemployed groups such as women, youth, and the elderly. AGP-LGP will apply CNFA’s past success to Ethiopia.

Worldwide, 195 million children suffer from malnutrition, which adversely affects their development and overall well-being. Approximately 26 percent of these children live in sub-Saharan Africa. And according to the International Food Policy Research Institute, the number of malnourished children in the region will rise 18 percent between 2001 and 2020. Fortunately, innovations such as school feeding programs and kitchen vegetable gardens are working to combat malnutrition and hunger in African children.

One organization, Seeds for Africa, has been instrumental in helping children gain access to local, nutritious fruits and vegetables. A central part of this organization’s work is teaching children the value of growing their own food by helping them to establish kitchen gardens and fruit tree orchards. Seeds for Africa funds kitchen vegetable garden development at primary schools in Malawi, Kenya, Uganda, and Sierra Leone.

In Kenya, Seeds for Africa coordinator Thomas Ndivo Muema has helped primary schools in the Nairobi region establish vegetable gardens and orchards of 200 fruit trees and has also supplied water tanks. In Uganda, fruit trees and vegetable gardens have been established at 77 schools around Kampala, the capital city. And in Sierra Leone, Seeds for Africa coordinator Abdul Hassan King has helped oversee tree planting projects in 50 primary schools and advised kitchen vegetable gardens operating at 15 other schools.

In 2011, Kellogg UK donated £6434 (US$9,946) to
